AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
325 PM CDT WED AUG 20 2014

.SHORT TERM...
CU FIELD CONTINUES TO DEVELOP AND THICKEN ALONG SURFACE TROUGH
RUNNING ACROSS OUR WRN ZONES...WITH A FEW ECHOES BEGINNING TO SHOW
UP ACROSS PARMER COUNTY AT 230 CDT. WATER VAPOR IMAGERY SHOWS THE
SUB-TROPICAL MOISTURE PLUME BENDING INTO WEST TEXAS...WITH A COUPLE
WEAK RIPPLES APPARENT MAINLY OVER NM...WHICH MAY RESULT IN SOME
MINOR ASCENT OVER WTX. PRECIP H2O VALUES WITHIN THE PLUME ARE NOT
QUITE AS ROBUST AS PREVIOUS INDICATIONS...ABOUT 1.2 INCHES PER RUC
ANALYSIS...WHICH IS JUST SLIGHTLY ABOVE AVG FOR THIS TIME OF YEAR.
STILL...LOCALIZED DOWNPOURS ARE POSSIBLE WITH RELATIVELY SLOW CELL
MOTION AND SOME INCREASE IN DEEP-LAYER MOISTURE EXPECTED BY EARLY
EVENING. STRONG WIND GUSTS WILL ALSO BE POSSIBLE IN THE VICINITY OF
THE STORMS GIVEN ABOUT 1000 J/KG OF DOWNDRAFT CAPE.

WE WILL KEEP THE HIGHEST POPS IN THE VICINITY OF THE SURFACE TROUGH
WITH DIMINISHING CHANCES FARTHER EAST...MAINLY WEST OF I-27. IT IS
NOT OUT OF THE QUESTION THAT WE COULD SEE A ROGUE SHOWER OR TWO OFF
THE CAPROCK BUT CHANCES APPEAR TOO SLIM TO MENTION IN THE FCST.
ACTIVITY SHOULD COME TO AN END BY MID-EVENING OR SO WITH ANOTHER
MILD AND QUIET NIGHT EXPECTED.

THE OVERALL PATTERN SHOULD CHANGE VERY LITTLE ON THURSDAY AS THE CWA
WILL REMAIN IN BETWEEN AN UPPER RIDGE OVER THE CENTRAL GULF COAST
AND A TROUGH MOVING THROUGH THE GREAT BASIN AND DESERT SW. THE
SURFACE TROUGH MAY DEVELOP A BIT FARTHER WEST ON THU...PERHAPS JUST
WEST OF THE STATE LINE...WHICH IN TURN MAY TAKE THE BEST CONVERGENCE
AND AFTERNOON CONVECTIVE INITIATION CHANCES TO THE WEST AS WELL.
HOWEVER...WITH SOME LINGERING UNCERTAINTY REGARDING THE POSITION OF
THE FEATURES WE WILL KEEP A BROAD AREA OF SLIGHT CHANCE ON THE
CAPROCK...WITH LOW CHANCE CATEGORY NEAR THE STATE LINE. HIGH TEMPS
THU ARE EXPECTED TO BE LOW TO MID 90S ON THE CAP...WITH MID TO UPPER
90S IN THE ROLLING PLAINS.

&&

.LONG TERM...
A WEAK SWLY FLOW ALOFT WILL DOMINATE THE SOUTH PLAINS THROUGH
EARLY NEXT WEEK AS THE REGION IS SANDWICHED IN BETWEEN TROUGHING
IN THE WEST AND STOUT RIDGING OVER MUCH OF THE MS RIVER VALLEY.
THE MOST DAY-TO-DAY VARIABILITY INVOLVES THE PLACEMENT AND
DEPTH OF MONSOONAL MOISTURE IN THIS OTHERWISE BENIGN SWLY FLOW
AND NAMELY HOW WELL THIS TRANSLATES INTO PRECIP CHANCES.
HOWEVER...A SUBTLE UPTICK IN THIS FLOW IS EXPECTED BY FRIDAY AS AN
OPEN WAVE LIFTS NORTHEAST FROM THE DESERT SOUTHWEST AND SPREADS
WEAK HEIGHT FALLS ACROSS OUR WRN COUNTIES. OF INTEREST...WATER
VAPOR SHOWS THIS WAVE IS ALREADY SOURCING SOME TROPICAL MOISTURE
FROM LOWELL...SO THE INGREDIENTS MAY BE COMING TOGETHER FOR A
BONAFIDE UNSETTLED PERIOD BY LATE FRIDAY FOR AREAS NEAR THE TX-NM
BORDER. ALTHOUGH MODELS ARE NOT OVERLY BULLISH WITH QPF ON FRI...WE
FEEL THE AFOREMENTIONED DETAILS WARRANT A DECENT CHANCE FOR PRECIP
IN OUR W-NWRN COUNTIES.

THE WEEKEND LOOKS TO FEATURE A GRADUAL EASTERLY DISPLACEMENT TO
THE LINGERING MONSOONAL MOISTURE PLUME...PERHAPS POISED MORE
SQUARELY OVER THE SOUTH PLAINS AND INTO OUR NERN ZONES AKIN TO THE
GFS. OPTED TO EXPAND SLIGHT CHANCE POPS EWD THROUGH THE WEEKEND TO
ACCOUNT FOR THIS TRANSITION...BUT THE PARENT MOISTURE PLUME MAY
VERY WELL BECOME EXHAUSTED BY THIS TIME AND REDUCED TO A SHALLOW
AND INSIGNIFICANT DEPTH.

NEXT WEEK STILL HOLDS SOME PROMISE FOR A COLD FROPA CONTINGENT ON
THE BEHAVIOR OF TROUGHING SHOWN TO OCCUPY THE NRN ROCKIES SOUTH
TO THE FOUR CORNERS. THE STRONGEST SOUTHWARD PUSH TO THIS FRONT
IN THE NRN PLAINS IS STILL FAVORED TO OCCUR LATE THIS WEEKEND IN
RESPONSE TO SURFACE CYCLOGENESIS NEAR OR JUST NORTH OF THE 49TH
PARALLEL...THOUGH RECENT MODELS NOW DELAY THIS FROPA LOCALLY BY
SOME 24 TO 48 HOURS GIVEN SECONDARY TROUGHING THROUGH THE FOUR
CORNERS WHICH WOULD EFFECTIVELY SLOW THE FRONT. MUCH DOUBT IS
THEREFORE CAST ON ANY NOTABLE COOLDOWN POTENTIAL BEFORE WEDNESDAY
AND ESPECIALLY ANY FURTHER CHANCES FOR PRECIP.

.AVIATION...
VFR CONDITIONS WILL PREVAIL AT BOTH TERMINALS NEXT 24 HRS. THERE
IS A REMOTE CHANCE OF TSRA IN THE VICNITY OF KLBB AND/OR KCDS
BETWEEN ABOUT 22 UTC AND 02 UTC BUT BULK OF THE CONVECTIVE ACTIVITY
EXPECTED TO REMAIN TO THE WEST. BREEZY S-SW SFC WINDS MAY BE
INFLUENCED BY AN T-STORM OUTFLOW BOUNDARY THIS EVENING...OTHERWISE
WE EXPECT TYPICAL DIURNAL VARIATION.

AVIATION...
INCREASING MOISTURE TO THE WEST OF KLBB TODAY WITH THUNDER CHANCES
EXPECTED TO REMAIN WEST AS WELL. MODEST SURFACE TROUGH WITH GUSTY
SOUTHERLY BREEZES LATE MORNING AND AFTERNOON. RMCQUEEN

PREV DISCUSSION... /ISSUED 337 AM CDT WED AUG 20 2014/

SHORT TERM...
THE EASTERN EDGE OF MONSOONAL MOISTURE WILL BEND ACROSS OUR WESTERN
ZONES THIS AFTERNOON AND EVENING WITH WEAK DYNAMIC SUPPORT BUT STILL
A LOW CHANCE FOR THUNDER. THIS APPEARS WELL HANDLED BY THE PREVIOUS
FORECAST AND RELATIVELY FEW CHANGES WERE MADE. A WEAK IMPULSE WILL
PULL OUT OF THE ROCKIES AS A SLIGHTLY MORE VIGOROUS WAVE SKIMS BY TO
THE NORTH...ALL AS UPPER RIDGE WILL BE IN THE PROCESS OF RELOCATING
EASTWARD DURING THE NEXT 24 HOURS. PRECIPITABLE WATER VALUES STILL
LOOK ON PACE TO IMPROVE CLOSE TO 1.5 INCHES NEAR WESTERN BORDER AND
CELL MOVEMENT WILL REMAIN RELATIVELY SLOW. ALSO...WE SHOULD SEE A
BIT INCREASED LOW LEVEL FLOW WITH SLIGHTLY DEEPER SURFACE TROUGHING
AND SLIGHTLY MORE DYNAMIC THUNDERSTORMS. BUT OVERALL HAZARDOUS
WEATHER RISK STILL APPEARS TOO LOW TO INCLUDE MENTION FOR NOW. THE
BULK OF STORM ACTIVITY IS LIKELY TO END BY MIDNIGHT WITH DEBRIS MID
LEVEL CLOUDS THROUGH THE LATE NIGHT WHICH WILL HOLD UP TEMPERATURES
CENTRAL AND EAST. A SEASONABLY WARM DAY IS EXPECTED TODAY...PERHAPS
UP A DEGREE OR TWO AS THE UPPER RIDGE TRANSLATES EAST. ONCE AGAIN...
FEW SIGNIFICANT CHANGES. RMCQUEEN

LONG TERM...
GLOBAL MODELS ARE COMING MORE INTO AGREEMENT WITH THE WEATHER
PATTERN FOR THE NEXT WEEK. AS PREVIOUSLY EXPECTED...A LEE TROF WILL
BE DRAPED ACROSS THE REGION WHICH WILL HELP SET US UP FOR A SHOT AT
PRECIP THURSDAY AFTERNOON/EVENING AS A SHORTWAVE TRAVELS AROUND THE
WESTERN EDGE OF THE RIDGE OVER EASTERN NM. I HAVE EXPANDED POPS
FARTHER EAST WITH SLIGHT CHANCES EXTENDING TO THE EDGE OF THE
CAPROCK WESTWARD AND KEPT CHANCES OVER OUR WESTERN ZONES. RAIN
CHANCES PERSIST EVERY AFTERNOON/EVENING THROUGH SUNDAY FOR THE
WESTERN THIRD OF THE FA AS THE SURFACE TROF STAYS PUT UNTIL THE MAIN
CHUNK OF ENERGY WITH THE TROF TO OUR WEST MAKES ITS WAY INTO THE
REGION IN THE FORM OF A SHORTWAVE. THE MAIN LONGWAVE TROF TO OUR
WEST WILL CONTINUE THROWING ENERGY OUR WAY INTO EARLY NEXT WEEK
KEEPING SOME HOPE FOR CONVECTION/PRECIP. FOR NOW...HOWEVER...POPS
HAVE BEEN KEPT JUST BELOW MENTION UNTIL THE WRINKLES CAN BE IRONED
OUT OF THE RUN TO RUN MODEL DIFFERENCES. BY MID WEEK A RIDGE WILL
BUILD BACK TO OUR WEST PUTTING US IN COOL NORTHWESTERLY FLOW. TEMPS
FOR THE NEXT WEEK WILL BE AROUND SEASONAL...POSSIBLY JUST
ABOVE...FOR THE FA WITH HIGHS IN THE UPPER 80S IN THE NORTHWEST ZONES
AND MID TO UPPER 90S IN THE EAST ZONES. LOWS WILL BE IN THE LOW 60S
OUT WEST TO THE LOW 70S OUT EAST.

POSSIBLITY OF MVFR STRATUS REACHING AS FAR NORTH AS THE SOUTH
PLAINS. ISOLATED TO SCATTERED TSRA EXPECTED TO DEVELOP WEDNESDAY
AFTN VCNTY OF THE TEXAS-NM STATE LINE WEST OF KLBB THEN TO MOVE TO
THE EAST AND NORTHEAST. THESE STORMS WILL APPROACH KLBB BUT

THE EVENING.

AVIATION...
ISOLATED SHOWERS LIKELY TO REMAIN SOUTH OF BOTH TERMINALS THIS
EVENING. SLIGHTLY HIGHER LOW LEVEL MOISTURE TO ADVECT INTO THE
AREA TONIGHT...PUT WINDS LIKELY TO STAY UP ENOUGH TO KEEP FOG AT
BAY. STRATUS NOT COMPLETELY OUT OF THE QUESTION...BUT SINCE NOT A
STRONG SIGNAL APPEARING IN THE MODELS WILL LEAVE OUT OF THE TAFS
ATTM.

PREV DISCUSSION... /ISSUED 319 PM CDT TUE AUG 19 2014/

SHORT TERM...
EARLY AFTERNOON ANALYSIS SHOWS A WEAK MID-LEVEL SHEAR AXIS
STRETCHING FROM CENTRAL OKLA DOWN TO THE BIG BEND. FAIRLY DEEP
MOISTURE RESIDED ACROSS THE AREA...ESPECIALLY OFF THE CAPROCK WHERE
PWATS ARE IN EXCESS OF 1.5 INCHES. SURFACE WINDS ARE PRETTY
WEAK...BUT TWO AREAS OF CONVERGENCE ARE APPARENT...ONE NORTH-SOUTH
AXIS IN THE ROLLING PLAINS AND ONE RUNNING FROM THE NW PERMIAN BASIN
INTO ERN NM. WE EXPECT A FEW TSTMS TO DEVELOP IN THESE AREAS THROUGH
EARLY EVENING. STORMS MOTION SHOULD BE VERY SLOW WITH ANY CELLS
QUICKLY BECOMING OUTFLOW DOMINANT. WE COULD SEE A STRONGER OUTFLOW
OR TWO PRODUCE VERY GUSTY WINDS. ANY ACTIVITY SHOULD DIMINISH BY MID
EVENING WITH SKIES BECOMING PARTLY CLOUDY OVERNIGHT. THE LOW-LEVEL
JET WILL BE A BIT STRONGER TONIGHT WHICH SHOULD KEEP ANY FOG AT
BAY...ALTHOUGH IT IS NOT OUT OF THE QUESTION SOME LOW STRATUS COULD
FORM EARLY WED MORNING. ON WEDNESDAY...SUB TROPICAL MOISTURE PLUME
CURRENTLY OVER NM AND FAR WEST TX WILL BEND NEWD INTO WEST
TEXAS...AND GUIDANCE SUGGESTS A LOW-LVL THETA-E RIDGE WILL DEVELOP
FROM SW TX INTO THE CENTRAL TX PANHANDLE...CUTTING ACROSS OUR WRN
ZONES. A WEAK MID-LEVEL TROUGH ADVANCING INTO NM WILL BRING SOME
SUBTLE LIFT AND SLIGHTLY STRONGER WESTERLY COMPONENT TO THE MID-LVL
WIND FIELD OVER OUR WRN ZONES. SCATTERED T-STORMS MAY DEVELOP NEAR
THE TX-NM BORDER BY MID TO LATE AFTERNOON. NO SEVERE WX IS
EXPECTED...BUT LOCALLY HEAVY RAIN AND STRONG WIND GUSTS WILL BE
POSSIBLE. TEMPS ARE EXPECTED TO REMAIN ABOUT THE SAME WED...WITH
HIGHS IN THE LOW 90S WEST TO MID 90S EAST.

LONG TERM...
SEMI-DIRTY UPPER RIDGE CURRENTLY OVER WEST TX IS SHOWN TO RELOCATE
WELL TO OUR EAST NEAR THE MISSISSIPPI RIVER VALLEY BY THURSDAY
MORNING WHILE REMAINING LARGELY UNCHANGED THROUGH EARLY NEXT WEEK.
THE MEAN UPPER FLOW LOCALLY WILL BE LARGELY FROM THE SOUTHWEST AND
AT TIMES CYCLONIC AS A FEW DECAYING WAVES GRAZE THE REGION. THE
TIMING OF THE FIRST OF THESE WAVES IS STILL IN QUESTION AS THE 12Z
ECMWF REMAINS THE LAGGARD COMPARED TO THE GEFS MEAN AND ESPECIALLY
THE GFS WHICH IS SOME 36 HOURS FASTER. WPC IS FAVORING A BLENDED
APPROACH FOR NOW WITH THIS FEATURE WHICH SEEMS BEST SUPPORTED BY
THE GEFS MEAN...SO FRIDAY MAY SEE AN EVEN BETTER OPPORTUNITY FOR
PRECIP ACROSS THE WESTERN HALF OF OUR CWA AS THIS WAVE GLANCES THE
REGION. HOWEVER...THE INHERITED POP GRIDS HOWEVER WERE LEFT LARGELY
IN CHECK THROUGH THE ENTIRE LONG TERM WINDOW AS CONFIDENCE IN THESE
SUBTLE DETAILS IS A BIT MURKY.

AT THE VERY LEAST THE MEAN AXIS OF MONSOONAL MOISTURE/HIGHER PWATS
WILL RESIDE NEAR THE NM STATE LINE THROUGH EARLY NEXT WEEK
COINCIDENT WITH A NEARLY STATIONARY SURFACE TROUGH. SUBTLE
EASTWARD SHIFTS TO THIS MOISTURE AXIS ARE CERTAINLY POSSIBLE JUST
ABOUT ANY DAY...BUT THIS MOISTURE WILL BE THINNING/NARROWING AS IT
FIGHTS A WESTWARD EXTENSION OF THE UPPER HIGH ATTEMPTING TO
RECLAIM WEST TX. POPS THEREFORE REMAIN SILENT AFTER FRI NIGHT.

BY EARLY NEXT WEEK...A SEASONABLY STRONG TROUGH TRACKING FROM THE
NRN ROCKIES INTO THE NRN PLAINS MAY SEND A SLOW-MOVING COLD FRONT
INTO OUR TERRITORY...BUT THIS IS TOO DISTANT TO CONSIDER
ENTERTAINING FURTHER OPPORTUNITIES FOR PRECIP. MAX TEMPS THROUGH
THE EXTENDED STILL LOOK TO REMAIN A TOUCH ABOVE CLIMO GIVEN NO
NOTABLE CHANGE TO DAILY THICKNESS TRENDS.

SHORT TERM...
EARLY AFTERNOON ANALYSIS SHOWS A WEAK MID-LEVEL SHEAR AXIS
STRETCHING FROM CENTRAL OKLA DOWN TO THE BIG BEND. FAIRLY DEEP
MOISTURE RESIDED ACROSS THE AREA...ESPECIALLY OFF THE CAPROCK WHERE
PWATS ARE IN EXCESS OF 1.5 INCHES. SURFACE WINDS ARE PRETTY
WEAK...BUT TWO AREAS OF CONVERGENCE ARE APPARENT...ONE NORTH-SOUTH
AXIS IN THE ROLLING PLAINS AND ONE RUNNING FROM THE NW PERMIAN BASIN
INTO ERN NM. WE EXPECT A FEW TSTMS TO DEVELOP IN THESE AREAS THROUGH
EARLY EVENING. STORMS MOTION SHOULD BE VERY SLOW WITH ANY CELLS
QUICKLY BECOMING OUTFLOW DOMINANT. WE COULD SEE A STRONGER OUTFLOW
OR TWO PRODUCE VERY GUSTY WINDS. ANY ACTIVITY SHOULD DIMINISH BY MID
EVENING WITH SKIES BECOMING PARTLY CLOUDY OVERNIGHT. THE LOW-LEVEL
JET WILL BE A BIT STRONGER TONIGHT WHICH SHOULD KEEP ANY FOG AT
BAY...ALTHOUGH IT IS NOT OUT OF THE QUESTION SOME LOW STRATUS COULD
FORM EARLY WED MORNING. ON WEDNESDAY...SUB TROPICAL MOISTURE PLUME
CURRENTLY OVER NM AND FAR WEST TX WILL BEND NEWD INTO WEST
TEXAS...AND GUIDANCE SUGGESTS A LOW-LVL THETA-E RIDGE WILL DEVELOP
FROM SW TX INTO THE CENTRAL TX PANHANDLE...CUTTING ACROSS OUR WRN
ZONES. A WEAK MID-LEVEL TROUGH ADVANCING INTO NM WILL BRING SOME
SUBTLE LIFT AND SLIGHTLY STRONGER WESTERLY COMPONENT TO THE MID-LVL
WIND FIELD OVER OUR WRN ZONES. SCATTERED T-STORMS MAY DEVELOP NEAR
THE TX-NM BORDER BY MID TO LATE AFTERNOON. NO SEVERE WX IS
EXPECTED...BUT LOCALLY HEAVY RAIN AND STRONG WIND GUSTS WILL BE
POSSIBLE. TEMPS ARE EXPECTED TO REMAIN ABOUT THE SAME WED...WITH
HIGHS IN THE LOW 90S WEST TO MID 90S EAST.

LONG TERM...
SEMI-DIRTY UPPER RIDGE CURRENTLY OVER WEST TX IS SHOWN TO RELOCATE
WELL TO OUR EAST NEAR THE MISSISSIPPI RIVER VALLEY BY THURSDAY
MORNING WHILE REMAINING LARGELY UNCHANGED THROUGH EARLY NEXT WEEK.
THE MEAN UPPER FLOW LOCALLY WILL BE LARGELY FROM THE SOUTHWEST AND
AT TIMES CYCLONIC AS A FEW DECAYING WAVES GRAZE THE REGION. THE
TIMING OF THE FIRST OF THESE WAVES IS STILL IN QUESTION AS THE 12Z
ECMWF REMAINS THE LAGGARD COMPARED TO THE GEFS MEAN AND ESPECIALLY
THE GFS WHICH IS SOME 36 HOURS FASTER. WPC IS FAVORING A BLENDED
APPROACH FOR NOW WITH THIS FEATURE WHICH SEEMS BEST SUPPORTED BY
THE GEFS MEAN...SO FRIDAY MAY SEE AN EVEN BETTER OPPORTUNITY FOR
PRECIP ACROSS THE WESTERN HALF OF OUR CWA AS THIS WAVE GLANCES THE
REGION. HOWEVER...THE INHERITED POP GRIDS HOWEVER WERE LEFT LARGELY
IN CHECK THROUGH THE ENTIRE LONG TERM WINDOW AS CONFIDENCE IN THESE
SUBTLE DETAILS IS A BIT MURKY.

AT THE VERY LEAST THE MEAN AXIS OF MONSOONAL MOISTURE/HIGHER PWATS
WILL RESIDE NEAR THE NM STATE LINE THROUGH EARLY NEXT WEEK
COINCIDENT WITH A NEARLY STATIONARY SURFACE TROUGH. SUBTLE
EASTWARD SHIFTS TO THIS MOISTURE AXIS ARE CERTAINLY POSSIBLE JUST
ABOUT ANY DAY...BUT THIS MOISTURE WILL BE THINNING/NARROWING AS IT
FIGHTS A WESTWARD EXTENSION OF THE UPPER HIGH ATTEMPTING TO
RECLAIM WEST TX. POPS THEREFORE REMAIN SILENT AFTER FRI NIGHT.

BY EARLY NEXT WEEK...A SEASONABLY STRONG TROUGH TRACKING FROM THE
NRN ROCKIES INTO THE NRN PLAINS MAY SEND A SLOW-MOVING COLD FRONT
INTO OUR TERRITORY...BUT THIS IS TOO DISTANT TO CONSIDER
ENTERTAINING FURTHER OPPORTUNITIES FOR PRECIP. MAX TEMPS THROUGH
THE EXTENDED STILL LOOK TO REMAIN A TOUCH ABOVE CLIMO GIVEN NO
NOTABLE CHANGE TO DAILY THICKNESS TRENDS.

.AVIATION...
VFR CONDITIONS WILL PREVAIL AT BOTH TERMINALS FOR THE NEXT 24
HOURS. THERE IS A LOW...ABOUT 20 PERCENT...CHANCE OF TSRA IN THE
VICINITY OF EITHER TERMINAL THIS AFTERNOON AND EARLY
EVENING...ALONG WITH THE POSSIBILITY OF A GUSTY T-STORM OUTFLOW
BOUNDARY. ALSO...THERE IS A CHANCE OF PATCHY LOW CEILINGS EARLY
WED MORNING...BUT CONFIDENCE IS LOW AT THIS TIME.

&&

.PREV DISCUSSION... /ISSUED 639 AM CDT TUE AUG 19 2014/

UPDATE...
HAVE UPDATED ZONES AND ISSUED DENSE FOG ADVISORY FOR AREAS WEST OF
THE CAPROCK ESCARPMENT. STRONG MOISTURE ADVECTION HAS BROUGHT
ABOUT RAPID FORMATION OF 1KFT FOG DECK WHICH SHOULD PERSIST AT
LEAST UNTIL MID MORNING BEFORE STARTING TO MIX OUT.

AVIATION...
FIRST CONCERN WILL BE IFR CONDITIONS AT KLBB. STRATUS/FOG FORMED
RAPIDLY EARLIER THIS MORNING AS MOIST AIR STREAMED INTO THE
REGION. CURRENT INDICATIONS SUGGEST FOG MAY DISSIPATE AROUND 14Z
THOUGH GIVEN DEPTH AND INTENSITY...MAY PERSIST AN HOUR OR TWO
LONGER.  UPPER LEVEL WEAKNESS IN THE CENTRAL US RIDGE ALONG WITH
MID LEVEL ANTICYCLONIC CIRCULATION SHOULD BE SUFFICIENT TO
INITIATE TSTMS MAINLY S OF KCDS AND E OF KLBB THIS AFTERNOON. SOME
UNCERTAINTY IN COVERAGE/EXTENT EXISTS AND WILL PUT LIKELIHOOD OF
CONVECTION ABOUT 15 PCT AT KLBB AND 20 PCT AT KCDS MAINLY BETWEEN
21Z AND 02Z. CONFIDENCE NUMBERS PRECLUDE EXPLICIT MENTION OF TSTM
IN TAF ATTM THOUGH TRENDS MAY DICTATE OTHERWISE LATER TODAY.
STRONG DOWNBURSTS WILL LIKELY BE AN ISSUE INVOF STORMS.

PREV DISCUSSION... /ISSUED 351 AM CDT TUE AUG 19 2014/

SHORT TERM...
FLOW ACROSS NORTH AMERICA IS CHARACTERIZED BY TROUGHINESS ON BOTH
COASTS WITH RIDGING ALONG 100W WITH THE EXCEPTION OF A WEAKNESS
LOCATED OVER CENTRAL TEXAS.  BROAD SYNOPTIC SCALE LIFT IS EVIDENT
FROM NWRN MEXICO INTO THE GREAT BASIN WITH ANOTHER LOBE ASSOCIATED
WITH THE AFOREMENTIONED WEAKNESS ACROSS THE SWRN 2/3RDS OF TEXAS.
THE BEST...ALBEIT WEAK UPPER LEVEL DIV-Q FIELDS WILL REMAIN OVER SE
TX THOUGH A FEW RIPPLES OF ENERGY AHEAD OF APPROACHING SOCAL LOW
WILL PROVIDE SOME EXTRA LIFT MAINLY TO OUR NORTHWEST.  MORE
IMPORTANTLY THOUGH MAY BE THE FACT THAT SUBSIDENCE ALOFT WILL BE
WEAK IN AN AIRMASS SUCH AS WE HAVE THIS MORNING.  GUIDANCE SUGGEST
THAT MONSOON-DERIVED MOISTURE WILL ADVECT INTO THE SOUTHEASTERN PART
OF OUR AREA LATER THIS MORNING MOST NOTABLY AT H7.  THIS WILL HELP
AID IN DESTABILIZATION AND SHOULD BE SUFFICIENT TO ESTABLISH
SCATTERED DEEP CONVECTION THOUGH SUBSIDENT INVERSION AROUND 550MB
MAY SERVE TO SUPPRESS UPDRAFTS INITIALLY.  WITH ANEMIC SHEAR
PROFILES...FAIRLY SHORT DURATION PULSE STORMS WITH OUTFLOW
REGENERATION PROCESSES APPEAR PROBABLE WITH STRONG WIND GUST
POTENTIAL.  INSOFAR AS SPATIAL EXTENT...THIS IS A BIT TRICKY.  A
WEAK AND BROAD MID LEVEL CIRCULATION SHOULD HELP PULL DRIER AIR FROM
THE NORTH AND NORTHEAST AROUND TO OUR WESTERN ZONES.  THETA E FIELDS
FROM THE SFC TO H7 DO SHOW A MINOR MAXIMUM FROM S TO N ACROSS OUR
CENTRAL ZONES.  HIGHS TODAY SHOULD BE A JUST A COUPLE OF DEGREES
ABOVE SEASONAL AVERAGES.

LONG TERM...
WED WILL START OFF WITH A DEVELOPING LEE TROF AS A CLOSED LOW OVER
SOCAL BEGINS ITS PUSH TOWARDS THE REGION. MODELS HAVE BEEN FAIRLY
CONSISTENT WITH DEVELOPING CONVECTION ALONG THIS TROF OVER OUR
WESTERN COUNTIES...WITH THE ECMWF SHOWING THE GREATEST COVERAGE. FOR
NOW THE INHERITED SLIGHT CHANCE POPS OVER OUR WESTERN ZONES LINE UP
WELL WITH THE FORECAST AND WILL REMAIN UNCHANGED. MODELS BEGIN TO
DIVERGE SLIGHTLY BEYOND WED NIGHT ON HOW THE CLOSED LOW OVER SOCAL
WILL EVOLVE. THE GFS OPENS THE LOW AND KICKS IT EASTWARD FAIRLY
QUICKLY WHILE THE NAM AND ECMWF BOTH HOLD THE LOW BACK OVER THE
NORTHERN BAJA PENINSULA UNTIL FRI MORNING...WHICH SEEMS A BIT MORE
FAVORABLE THAN THE GFS. THE AFOREMENTIONED LEE TROF WILL STILL BE
DRAPED ACROSS OUR WESTERN ZONES ON THUR WHICH WILL BRING ANOTHER
CHANCE FOR CONVECTION THUR EVENING. HIGHEST PRECIP CHANCES WILL BE
KEPT ALONG THE TX/NM STATE LINE AS ENERGY FROM THE LOW WILL STILL BE
TO THE WEST OF THE FA. AS WE GET INTO THE WEEKEND...WE WILL BE IN A
PATTERN OF HAVING A TROF TO OUR WEST AND RIDGE TO OUR EAST. USUALLY
THIS WOULD BE A FAIRLY FAVORABLE PATTERN FOR PRECIP...HOWEVER IT
LOOKS LIKE THE HIGH WILL BULGE JUST A BIT FARTHER WEST THAN WOULD BE
WANTED FOR STORMS WHILE THE TROF STAYS JUST A BIT TOO FAR NORTH.
WHILE WE MAY NOT BENEFIT FULLY FROM THE MONSOONAL MOISTURE...AREAS
TO OUR WEST AND NORTH SHOULD RECEIVE BENEFICIAL RAINS INTO MID
NEXT WEEK. TEMPS THROUGH NEXT WEEK SHOULD STAY AROUND SEASONAL

NATIONAL WEATHER SERVICE LUBBOCK TX
610 AM CDT TUE AUG 19 2014

.UPDATE...
HAVE UPDATED ZONES AND ISSUED DENSE FOG ADVISORY FOR AREAS WEST OF
THE CAPROCK ESCARPMENT. STRONG MOISTURE ADVECTION HAS BROUGHT
ABOUT RAPID FORMATION OF 3KFT FOG DECK WHICH SHOULD PERSIST AT
LEAST UNTIL MID MORNING BEFORE STARTING TO MIX OUT.

&&

.AVIATION...
FIRST CONCERN WILL BE IFR CONDITIONS AT KLBB. STRATUS/FOG FORMED
RAPIDLY EARLIER THIS MORNING AS MOIST AIR STREAMED INTO THE
REGION. CURRENT INDICATIONS SUGGEST FOG MAY DISSIPATE AROUND 14Z
THOUGH GIVEN DEPTH AND INTENSITY...MAY PERSIST AN HOUR OR TWO
LONGER.  UPPER LEVEL WEAKNESS IN THE CENTRAL US RIDGE ALONG WITH
MID LEVEL ANTICYCLONIC CIRCULATION SHOULD BE SUFFICIENT TO
INITIATE TSTMS MAINLY S OF KCDS AND E OF KLBB THIS AFTERNOON. SOME
UNCERTAINTY IN COVERAGE/EXTENT EXISTS AND WILL PUT LIKELIHOOD OF
CONVECTION ABOUT 15 PCT AT KLBB AND 20 PCT AT KCDS MAINLY BETWEEN
21Z AND 02Z. CONFIDENCE NUMBERS PRECLUDE EXPLICIT MENTION OF TSTM
IN TAF ATTM THOUGH TRENDS MAY DICTATE OTHERWISE LATER TODAY.
STRONG DOWNBURSTS WILL LIKELY BE AN ISSUE INVOF STORMS.

PREV DISCUSSION... /ISSUED 351 AM CDT TUE AUG 19 2014/

SHORT TERM...
FLOW ACROSS NORTH AMERICA IS CHARACTERIZED BY TROUGHINESS ON BOTH
COASTS WITH RIDGING ALONG 100W WITH THE EXCEPTION OF A WEAKNESS
LOCATED OVER CENTRAL TEXAS.  BROAD SYNOPTIC SCALE LIFT IS EVIDENT
FROM NWRN MEXICO INTO THE GREAT BASIN WITH ANOTHER LOBE ASSOCIATED
WITH THE AFOREMENTIONED WEAKNESS ACROSS THE SWRN 2/3RDS OF TEXAS. THE
BEST...ALBEIT WEAK UPPER LEVEL DIV-Q FIELDS WILL REMAIN OVER SE TX
THOUGH A FEW RIPPLES OF ENERGY AHEAD OF APPROACHING SOCAL LOW WILL
PROVIDE SOME EXTRA LIFT MAINLY TO OUR NORTHWEST.  MORE IMPORTANTLY
THOUGH MAY BE THE FACT THAT SUBSIDENCE ALOFT WILL BE WEAK IN AN
AIRMASS SUCH AS WE HAVE THIS MORNING.  GUIDANCE SUGGEST THAT
MONSOON-DERIVED MOISTURE WILL ADVECT INTO THE SOUTHEASTERN PART OF
OUR AREA LATER THIS MORNING MOST NOTABLY AT H7.  THIS WILL HELP AID
IN DESTABILIZATION AND SHOULD BE SUFFICIENT TO ESTABLISH SCATTERED
DEEP CONVECTION THOUGH SUBSIDENT INVERSION AROUND 550MB MAY SERVE TO
SUPPRESS UPDRAFTS INITIALLY.  WITH ANEMIC SHEAR PROFILES...FAIRLY SHORT
DURATION PULSE STORMS WITH OUTFLOW REGENERATION PROCESSES APPEAR
PROBABLE WITH STRONG WIND GUST POTENTIAL.  INSOFAR AS SPATIAL
EXTENT...THIS IS A BIT TRICKY.  A WEAK AND BROAD MID LEVEL
CIRCULATION SHOULD HELP PULL DRIER AIR FROM THE NORTH AND NORTHEAST
AROUND TO OUR WESTERN ZONES.  THETA E FIELDS FROM THE SFC TO H7 DO
SHOW A MINOR MAXIMUM FROM S TO N ACROSS OUR CENTRAL ZONES.  HIGHS
TODAY SHOULD BE A JUST A COUPLE OF DEGREES ABOVE SEASONAL AVERAGES.

LONG TERM...
WED WILL START OFF WITH A DEVELOPING LEE TROF AS A CLOSED LOW OVER
SOCAL BEGINS ITS PUSH TOWARDS THE REGION. MODELS HAVE BEEN FAIRLY
CONSISTENT WITH DEVELOPING CONVECTION ALONG THIS TROF OVER OUR
WESTERN COUNTIES...WITH THE ECMWF SHOWING THE GREATEST COVERAGE. FOR
NOW THE INHERITED SLIGHT CHANCE POPS OVER OUR WESTERN ZONES LINE UP
WELL WITH THE FORECAST AND WILL REMAIN UNCHANGED. MODELS BEGIN TO
DIVERGE SLIGHTLY BEYOND WED NIGHT ON HOW THE CLOSED LOW OVER SOCAL
WILL EVOLVE. THE GFS OPENS THE LOW AND KICKS IT EASTWARD FAIRLY
QUICKLY WHILE THE NAM AND ECMWF BOTH HOLD THE LOW BACK OVER THE
NORTHERN BAJA PENINSULA UNTIL FRI MORNING...WHICH SEEMS A BIT MORE
FAVORABLE THAN THE GFS. THE AFOREMENTIONED LEE TROF WILL STILL BE
DRAPED ACROSS OUR WESTERN ZONES ON THUR WHICH WILL BRING ANOTHER
CHANCE FOR CONVECTION THUR EVENING. HIGHEST PRECIP CHANCES WILL BE
KEPT ALONG THE TX/NM STATE LINE AS ENERGY FROM THE LOW WILL STILL BE
TO THE WEST OF THE FA. AS WE GET INTO THE WEEKEND...WE WILL BE IN A
PATTERN OF HAVING A TROF TO OUR WEST AND RIDGE TO OUR EAST. USUALLY
THIS WOULD BE A FAIRLY FAVORABLE PATTERN FOR PRECIP...HOWEVER IT
LOOKS LIKE THE HIGH WILL BULGE JUST A BIT FARTHER WEST THAN WOULD BE
WANTED FOR STORMS WHILE THE TROF STAYS JUST A BIT TOO FAR NORTH.
WHILE WE MAY NOT BENEFIT FULLY FROM THE MONSOONAL MOISTURE...AREAS
TO OUR WEST AND NORTH SHOULD RECEIVE BENEFICIAL RAINS INTO MID
NEXT WEEK. TEMPS THROUGH NEXT WEEK SHOULD STAY AROUND SEASONAL
AVERAGES...POSSIBLY JUST A BIT ABOVE.

VFR CONDITIONS WILL CONTINUE THROUGH THE NEXT 24 HOURS.

.PREV DISCUSSION... /ISSUED 232 PM CDT MON AUG 18 2014/

SHORT TERM...
A FEW SHOWERS AND THUNDERSTORMS ROTATING WWD FROM AN UPPER LOW
SITTING OVER WEST CENTRAL TEXAS TO SKIRT ACROSS THE FAR SRN ZONES
THIS AFTN BUT CURRENTLY THINK THAT SINCE THESE ARE LIKELY SO
DEPENDENT ON INSTABILITY THEY ARE UNLIKELY TO CONTINUE MUCH PAST 00Z
IF AT ALL. ATTM WILL WITH POPS JUST BELOW SLIGHT CHANCE MENTION IN
THE POST-00Z TIME FRAME AS EXPECT ANY ACTIVITY LIKELY TO REMAIN JUST
SOUTH OF THE FCST AREA IN AREA OF HIGHER SFC DEW POINTS AND SLIGHTLY
BETTER DEEPER MOISTURE PER WATER VAPOR IMAGERY.

FOCUS THEN SHIFTS TO TUESDAY. MODELS PROG THE LOW NEAR SAN ANGELO TO
GET PICKED UP TUESDAY BY INCREASING SWLY FLOW OVER THE REGION AS THE
RIDGE OVER THE ROCKIES BREAKS DOWN IN IN RESPONSE TO AN UPPER LOW
DIVING SWD ALONG THE CALIF COAST. AS A RESULT WILL SEE INCREASED MID
LEVEL MOISTURE...SLIGHTLY COOLER MID LEVEL TEMPERATURES...AND A
SLIGHT INCREASE IN LOW LEVEL MOISTURE WORK NWD DURING THE DAY.
HOWEVER...MODELS HAVE A RELATIVE DEARTH OF QPF ACROSS THE FCST AREA
AND OBJECTIVE GUIDANCE IS EVEN MORE PESSIMISTIC. OF NOTE IS THAT THE
LOW WILL BEGIN FILLING AS IT STARTS ITS MOVE TO THE NORTH WITH
DECREASING MID LEVEL MOISTURE AND WARMER MID LEVEL TEMPS THAN SEEN
TODAY...SO THAT LIKELY HAS MUCH TO DO WITH THE LIMITED PRECIP IN THE
MODELS. THAT SAID...RECENT DAYS HAVE SEEN REALITY BEING A LITTLE
WETTER THAN MODELS HAVE BEEN INDICATING SO CERTAINLY THINK THERE IS
A POSSIBILITY OF SEEING SOME ISOLATED SHOWERS DEVELOP DURING PEAK
HEATING TUESDAY AFTN ALTHOUGH EXPECT COVERAGE TO BE QUITE LIMITED.
STILL...SITUATION SUPPORTS INSERTING MENTION OF SLIGHT CHANCE
TUESDAY AFTN. WILL PLACE THAT MENTION ACROSS THE ROLLING PLAINS
WHERE MODELS CURRENTLY PROG THE BEST COMBINATION OF DEEP MOISTURE AND
COOL POOL ALOFT. TEMPS LIKELY TO BE A BIT COOLER THAN PREVIOUSLY
EXPECTED AS WELL GIVEN THE ABOVE FACTORS AND WILL TREND TOWARD THE
COOLER MET NUMBERS FOR MOST OF THE FCST AREA.

LONG TERM...
FEW CHANGES MADE TO THIS ITERATION OF THE LONG TERM
FORECAST...ALTHOUGH MEDIUM RANGE GUIDANCE APPEARS TO BE GRADUALLY
CONVERGING ON A COMMON SOLUTION DURING THE LATE WEEK AND WEEKEND
TIME FRAME.  OVER THE NEXT SEVERAL DAYS...THE LARGE SCALE UPPER FLOW
PATTERN WILL GRADUALLY TRANSITION TO A HIGHLY AMPLIFIED
PATTERN...WITH A RELATIVELY DEEP TROUGH DIGGING INTO THE MOUNTAIN
WEST...AND A STOUT UPPER HIGH ROUGHLY ALIGNED WITH THE MISSISSIPPI
VALLEY.  THIS WILL PLACE WEST TEXAS ALMOST DIRECTLY BETWEEN THE
TWO...WITHIN A REGIME OF INCREASING SOUTHWESTERLY UPPER FLOW.  AS
THIS OCCURS...THE MONSOONAL MOISTURE PLUME WILL BEGIN TO SHIFT
EASTWARD...WHICH IS EXPECTED TO INTRODUCE CHANCES FOR PRECIPITATION
ACROSS AT LEAST THE WESTERN SOUTH PLAINS BEGINNING WEDNESDAY
AFTERNOON.

AT THIS POINT...GUIDANCE IS STILL RELATIVELY SPLIT ON
THE SYNOPTIC EVOLUTION...AS THE ECMWF IS APPROXIMATELY 24 HOURS
SLOWER IN EJECTING A POTENT SHORTWAVE NORTHEASTWARD ALONG THE
PERIPHERY OF THE STOUT UPPER HIGH.  WHENEVER THIS OCCURS...LIKELY
DURING THE THURSDAY/FRIDAY TIME FRAME...THE WESTERN SOUTH PLAINS WILL
STAND A REASONABLE CHANCE TO SEE SCATTERED THUNDERSTORM
DEVELOPMENT...ALTHOUGH WITH A STRONG SOUTHERLY COMPONENT TO THE
STEERING FLOW IT REMAINS RELATIVELY UNCERTAIN JUST HOW FAR EAST THIS
ACTIVITY WILL EXTEND INTO THE REGION.  WHILE TIMING REMAINS A
CONCERN...THE LATEST ITERATION OF THE ECMWF SEEMS TO BE CATCHING ON
TO THE FASTER TROUGH EJECTION...ALTHOUGH AS MENTIONED BEFORE IT
REMAINS MUCH SLOWER THAN THE GFS.  GIVEN THE TREND THOUGH...HAVE
OPTED TO SLIGHTLY INCREASE POPS ACROSS THE EXTREME WESTERN SOUTH
PLAINS ALONG THE TEXAS NEW MEXICO STATE LINE FOR THE LATE THURSDAY
TIME FRAME...AND HAVE MAINTAINED SLIGHT CHANCES ACROSS
WESTERN AND NORTHERN PORTIONS OF THE SOUTH PLAINS THROUGH FRIDAY
EVENING AS WELL.  ANOTHER POINT WORTH NOTING DURING THE
THURSDAY/FRIDAY TIME FRAME IS A MARKED INCREASE IN WIND SHEAR
ASSOCIATED WITH THE PASSING UPPER WAVE...WHICH MAY LEAD TO MORE
ORGANIZED THUNDERSTORMS THAN WE`VE SEEN IN THE RECENT
PAST...INCLUDING POTENTIALLY A BRIEF WINDOW FOR STRONG TO SEVERE
THUNDERSTORMS.

BEYOND LATE FRIDAY UNCERTAINTY REMAINS HIGH...ALTHOUGH THERE WILL
LIKELY BE A LULL IN ACTIVITY AS THE AFOREMENTIONED TROUGH EXITS THE
REGION AND THE WESTERN PERIPHERY OF THE RIDGE BUILDS SLIGHTLY
WESTWARD.  THIS MAY NOT BE ENOUGH TO PREVENT A FEW
SHOWERS/THUNDERSTORMS ACROSS THE NORTHWESTERN SOUTH
PLAINS...ESPECIALLY IF WE CAN MAINTAIN SOME WESTERLY COMPONENT OF
THE UPPER STEERING FLOW...BUT WILL CONTINUE TO KEEP BELOW EXPLICIT
MENTION UNTIL MORE CERTAINTY EXISTS.  THROUGHOUT THE PERIOD...LITTLE
VARIATION IN TEMPERATURES CAN BE EXPECTED...WITH SLIGHTLY ABOVE
NORMAL HIGH TEMPERATURES IN THE LOW 90S TO NEAR 100 DEGREES...AND
LOWS BETWEEN THE LOW 60S TO LOW 70S.

STAND A REASONABLE CHANCE TO SEE SCATTERED THUNDERSTORM
DEVELOPMENT...ALTHOUGH WITH A STRONG SOUTHERLY COMPONENT TO THE
STEERING FLOW IT REMAINS RELATIVELY UNCERTAIN JUST HOW FAR EAST THIS
ACTIVITY WILL EXTEND INTO THE REGION.  WHILE TIMING REMAINS A
CONCERN...THE LATEST ITERATION OF THE ECMWF SEEMS TO BE CATCHING ON
TO THE FASTER TROUGH EJECTION...ALTHOUGH AS MENTIONED BEFORE IT
REMAINS MUCH SLOWER THAN THE GFS.  GIVEN THE TREND THOUGH...HAVE
OPTED TO SLIGHTLY INCREASE POPS ACROSS THE EXTREME WESTERN SOUTH
PLAINS ALONG THE TEXAS NEW MEXICO STATE LINE FOR THE LATE THURSDAY
TIME FRAME...AND HAVE MAINTAINED SLIGHT CHANCES ACROSS
WESTERN AND NORTHERN PORTIONS OF THE SOUTH PLAINS THROUGH FRIDAY
EVENING AS WELL.  ANOTHER POINT WORTH NOTING DURING THE
THURSDAY/FRIDAY TIME FRAME IS A MARKED INCREASE IN WIND SHEAR
ASSOCIATED WITH THE PASSING UPPER WAVE...WHICH MAY LEAD TO MORE
ORGANIZED THUNDERSTORMS THAN WE`VE SEEN IN THE RECENT
PAST...INCLUDING POTENTIALLY A BRIEF WINDOW FOR STRONG TO SEVERE
THUNDERSTORMS.

BEYOND LATE FRIDAY UNCERTAINTY REMAINS HIGH...ALTHOUGH THERE WILL
LIKELY BE A LULL IN ACTIVITY AS THE AFOREMENTIONED TROUGH EXITS THE
REGION AND THE WESTERN PERIPHERY OF THE RIDGE BUILDS SLIGHTLY
WESTWARD.  THIS MAY NOT BE ENOUGH TO PREVENT A FEW
SHOWERS/THUNDERSTORMS ACROSS THE NORTHWESTERN SOUTH
PLAINS...ESPECIALLY IF WE CAN MAINTAIN SOME WESTERLY COMPONENT OF
THE UPPER STEERING FLOW...BUT WILL CONTINUE TO KEEP BELOW EXPLICIT
MENTION UNTIL MORE CERTAINTY EXISTS.  THROUGHOUT THE PERIOD...LITTLE
VARIATION IN TEMPERATURES CAN BE EXPECTED...WITH SLIGHTLY ABOVE
NORMAL HIGH TEMPERATURES IN THE LOW 90S TO NEAR 100 DEGREES...AND
LOWS BETWEEN THE LOW 60S TO LOW 70S.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
1222 PM CDT MON AUG 18 2014

.UPDATE...
WILL ISSUE A QUICK UPDATE TO INSERT MENTION OF ISOLATED SHOWERS
ACROSS THE SERN ZONES WHERE A FEW SMALL SCALE SHOWERS HAVE ALREADY
DEVELOPED. THIS AREA IS ON THE NWRN PERIFERY OF AN UPPER LEVEL LOW
CENTERED OVER WEST CENTRAL TEXAS. ALSO SEEING SOME DECENT
INSTABILITY THERE AS TEMPS HAVE WARMED INTO THE UPPER 80S WHILE
DEW POINT TEMPS HOLD IN THE MID 60S. CONTINUED MODEST LOW LEVEL
MOISTURE ADVECTION INTO THAT AREA SUGGESTS SHOWER POTENTIAL TO
LAST THROUGH THE AFTN.

SHORT TERM...
A FAIRLY BENIGN WEATHER PATTERN IS IN STORE FOR TODAY AND TONIGHT AS
A RIDGE OF HIGH PRESSURE SITS OVER THE REGION. WV SHOWS A SHORTWAVE
ALONG THE EDGE OF THE RIDGE WELL SOUTH OF THE FA WHICH IS WHERE THE
BEST CHANCES FOR PRECIP WILL BE TODAY. BIGGEST CHANGE TO THE
FORECAST IS HIGHS BEING LOWERED BY A DEGREE OR TWO AS 500 MB HEIGHTS
ARE SLIGHTLY LOWER THAN YESTERDAY. OVERNIGHT LOWS WILL BE RELATIVELY
MILD RANGING FROM THE MID 60S TO THE LOW 70S.

LONG TERM...
UPPER LEVEL RIDGE WILL BEGIN TO SHIFT EASTWARD MORE OR LESS
BISECTING THE COUNTRY N/S BY LUNCHTIME ON TUESDAY WHILE UPPER LEVEL
LOW DIGS INTO SRN CALIFORNIA NORTH OF A PROGGED TROPICAL SYSTEM
AROUND 20N121W. THIS TROPICAL FEATURE CONTINUES TO COMPLICATE THE
EJECTION STRATEGY OF THE SOCAL LOW WITH THE GFS MUCH MORE
PROGRESSIVE THAN INDICATED BY THE ECM. EITHER WAY...WE ARE LOOKING
FOR SOUTHWESTERLY FLOW ALOFT DURING MUCH OF THE EXTENDED. THAT
MEANS THE SURFACE TROUGH TO OUR WEST WILL TAKE ON A SLOSHING
NATURE AND BRING A RISK OF STORM ACTIVITY ESPECIALLY OUT WEST.

WITH THE SLOWED PROGRESSION OF THE UPPER LOW...GUIDANCE HAS BACKED
OFF ON THE RISK OF STORMS ALONG THE TX/NM STATE LINE ON TUESDAY.
HOWEVER...AT ISO-SCT CB DEVELOPMENT WILL PROBABLY APPROACH/IMPINGE
ON THE NORTHWESTERN ZONES WED AFTN AND AGAIN ON THURSDAY ALONG
THETA-E RIDGE. CURRENT THINKING IS THAT EITHER OF THE TWO EJECTION
STRATEGIES WILL PROBABLY SUPPORT MENTIONABLE POPS INTO FRIDAY.
HOWEVER...BEYOND THAT...WILL ELECT TO KEEP THINGS DRY GIVEN

.SHORT TERM...
THE MID-LEVEL MOISTURE PLUME THAT BROUGHT SCATTERED THUNDERSTORMS TO
PARTS OF THE CWA THE PAST COUPLE OF DAYS HAS NOW SHIFTED TO THE
SOUTH AND EAST OF THE AREA...TAKING THE BETTER DEEP LAYER MOISTURE
AND THUNDERSTORM CHANCES WITH IT. EVEN SO...SURFACE DEWPOINTS REMAIN
IN THE 50S TO LOW 60S...WITH PWATS STILL HANGING AROUND TO SLIGHTLY
ABOVE 1 INCH. THIS RESIDUAL MOISTURE COUPLED WITH STRONG HEATING WAS
RESULTING IN MODEST MLCAPES OF 1000-1500 J/KG WITH MINIMAL CIN AS OF
THE 19Z SPC MESOSCALE ANALYSIS. THESE FACTORS ALONG WITH LIGHT
UPSLOPE FLOW COULD YET TRIGGER A ROGUE SHOWER OR STORM ALMOST
ANYWHERE IN THE AREA...THOUGH THE DRYING UPPER LEVELS AND BUILDING
UPPER LEVEL RIDGING FROM THE WEST SHOULD TEND TO LIMIT OVERALL STORM
DEVELOPMENT...COVERAGE AND DURATION. IN GENERAL...HAVE MAINTAINED
UNMENTIONABLE POPS AROUND 10 PERCENT FOR MUCH OF THE FA...WITH THE
EXCEPTION OF THE FAR SOUTHERN ZONES WHERE WEAK SURFACE CONVERGENCE
WAS OCCURRING ALONG A RESIDUAL BOUNDARY...AND BETTER CUMULUS
DEVELOPMENT HAS BEEN NOTED IN VISIBLE SATELLITE IMAGERY. IF/WHERE
STORMS DEVELOP THE WEAK WIND SHEAR ENVIRONMENT WILL SUPPORT
PULSE-TYPE ACTIVITY CAPABLE OF PRODUCING GUSTY WINDS. IN
ADDITION...A SLOW SOUTH OR SOUTHWEST STORM MOTION ALONG WITH
SUFFICIENT MOISTURE MAY ALLOW FOR A FEW LOCALLY HEAVY DOWNPOURS. ANY
CONVECTION SHOULD QUICKLY DIMINISH THIS EVENING WITHOUT ANY NOTABLE
UPPER LEVEL SUPPORT.

THE UPPER RIDGING CENTER ACROSS THE SOUTHWEST WILL EDGE THIS WAY
INTO MONDAY...WITH NORTHEASTERLY MID-LEVEL FLOW PROGGED TO BRING
EVEN DRIER AIR ALOFT OVER THE SOUTH PLAINS. THIS WILL FURTHER SQUASH
STORM CHANCES ON MONDAY...WITH A DRY DAY THE MOST LIKELY RESULT.

IT WILL BE ANOTHER MILD NIGHT TONIGHT...WITH LOWS IN THE 60S AND
LOWER 70S. TYPICAL AUGUST HEAT WILL FOLLOW AGAIN TOMORROW WITH HIGHS
SEVERAL DEGREES ABOVE AVERAGE.

&&

.LONG TERM...
MODELS CONTINUE TO PROG THE BREAKDOWN OF THE WRN CONUS UPPER RIDGE
EARLY IN THE WEEK AS AN UPPER LOW NOTED OVER PUGET SOUND THIS AFTN
SAGS SWD ALONG THE WEST COAST. FCST AREA WILL END UP IN THE AREA
BETWEEN THIS LOW OVER CALIF AND THE BERMUDA HIGH THAT IS PROGGED
TO AMPLIFY OVER THE SERN CONUS AND OHIO VALLEY. WILL ALSO SEE A
SERIES OF SHORT WAVE TROUGHS EJECTED FROM THE WEST COAST TROUGH
ACROSS THE CNTL AND NRN PLAINS. THE COMBINATION OF THESE FEATURES
WILL DRAW MID-LEVEL MONSOONAL MOISTURE EWD ACROSS NEW MEXICO
TOWARD THE SRN HIGH PLAINS...POSSBILY AS EARLY AS TUESDAY WITH
BEST CHANCES FOR PRECIP ACROSS THE WRN PART OF THE FCST AREA
COMING THURSDAY. WILL INSERT MENTION AT THIS POINT FOR WEDNESDAY
AND THURSDAY WITH POSSIBLITY OF EXPANSION TO TUESDAY...FRIDAY AND
SATURDAY SHOULD CONFIDENCE INCREASE WITH FUTURE MODEL RUNS. THIS

MONDAY MORNING. WINDS WILL BE LIGHT AS THEY SHIFT AROUND THE DIAL
FROM NORTHEAST EARLY THIS AFTERNOON TO EASTERLY BY LATE AFTERNOON

COUNTIES AS RESIDUAL SURFACE BOUNDARIES REMAIN FROM LAST NIGHTS
STORMS. HIGH TEMPS WILL BE WARM BUT WILL BE NOT OUT OF CONTROL AS
WINDS AT THE SURFACE WILL BE OUT OF THE EAST/EAST NORTHEAST FOR
MUCH OF THE DAY.

LONG TERM...
HIGH PRESSURE ALOFT WILL SHIFT EASTWARD TOWARD WEST TEXAS THROUGH
THE FIRST PART OF THIS COMING WEEK AS TROUGH DEEPENS ALONG THE
CALIFORNIA COAST.  THIS TROUGH CONTINUES TO BE HANDLED SOMEWHAT

CONVERGING ON A PATTERN OF VERY SLOW EASTWARD PROGRESSION AS HAS
BEEN EVIDENCED BY THE ECM SOLUTION THE PAST FEW NIGHTS.
SOUTHWESTERLY FLOW ALOFT LOOKS TO BE A BIT MORE LIKELY LATE IN THE

MID/HIGH CLOUDS OVERNIGHT WILL THIN BY DAYBREAK THEN RETURN SUN

TODAY AS WINDS ALOFT TURN MORE NERLY PUSHING MOISTURE AXIS SOUTH.

&&

PREV DISCUSSION... /ISSUED 241 PM CDT SAT AUG 16 2014/

SHORT TERM...
BIGGEST CHALLENGE TODAY IS QUANTIFYING STORM CHANCES OVER THE NEXT
24 HOURS WITHIN WEAKLY FORCED FLOW...THOUGH AN OVERALL DOWNWARD
TREND IN COVERAGE IS EXPECTED FROM YESTERDAY.

EARLY AFTERNOON WATER VAPOR IMAGERY SHOWS THAT THE MONSOONAL
MOISTURE PLUME WAS CONTINUING TO BEND MORE EASTWARD FROM SOUTHERN
NEW MEXICO AND FAR WEST TEXAS THROUGH MUCH OF OKLAHOMA AND NORTH
TEXAS...INCLUDING OVER THE SOUTH PLAINS. HOWEVER...THE RICHEST
TROPOSPHERIC MOISTURE HAS SHIFTED JUST TO THE SOUTH AND EAST OF THE
CWA BEHIND A WEAK EMBEDDED MID-LEVEL SHORTWAVE TROUGH...THOUGH
ANOTHER POCKET OF REMNANT RICHER MID-LEVEL MOISTURE IS IN PLACE
ACROSS THE WESTERN OKLAHOMA AND TEXAS PANHANDLES. ALOFT...THE
MID-LEVEL STEERING FLOW HAS TURNED MORE NORTH-TO-SOUTH BEHIND THE
WEAK DEPARTING SHORTWAVE AND DOWNSTREAM OF THE EXPANSIVE
SOUTHWESTERN HIGH. AT THE SURFACE...A RATHER WEAK AND SOMEWHAT
ERRATIC WIND FIELD WAS IN PLACE WITH A WEAK PRESSURE GRADIENT OVER
THE SOUTH PLAINS REGION. SURFACE MOISTURE WAS HOLDING IN PLACE WITH
DEWPOINTS FROM THE MIDDLE 50S TO LOWER 60S COMMON AND COUPLED WITH
STRONG HEATING...THIS WAS YIELDING MODEST INSTABILITY AND WEAKENING
CONVECTIVE INHIBITION. THIS ENVIRONMENT COULD SUPPORT AN ISOLATED
THUNDERSTORM ALMOST ANYWHERE AS WE HEAD THROUGH PEAK HEATING. THAT
SAID...CONVECTIVE ACTIVITY CURRENTLY DEVELOPING ACROSS THE WESTERN
PANHANDLES AND NORTHEAST AND EAST-CENTRAL NEW MEXICO WILL LIKELY
BRING THE BEST SHOT OF STORMS TO AFFECT THE FA LATE THIS AFTERNOON
AND THIS EVENING AS THEY TRACK SOUTHWARD AND SOUTHEASTWARD.
HENCE...WE HAVE MAINTAINED A SCATTERED THUNDERSTORM MENTION ACROSS
MOST OF THE WESTERN ZONES THROUGH THIS EVENING. ANOTHER POSSIBLE
FOCUS FOR CONVECTIVE DEVELOPMENT WILL BE IN THE ROLLING PLAINS WHERE
SOUTHERLY BREEZES IMPINGE UPON THE LIGHT WIND FIELD TO THE NORTH.
RESPECTABLE PWATS IN EXCESS OF 1.2 INCHES AND SLOW STORM MOTIONS
WILL AGAIN SUPPORT A LOCALLY HEAVY RAIN THREAT WHILE A HOT AND
DEEPLY MIXED BOUNDARY LAYER WILL FAVOR GUSTY OUTFLOWS WITH THE
STRONGER STORMS. ANY ACTIVITY WILL GRADUALLY DECREASE AND SHIFT
SOUTHWARD THROUGH THE LATE EVENING HOURS.

A NORTHEAST COMPONENT TO THE MID-LEVEL FLOW WILL THEN BRING IN
SLIGHTLY DRIER AIR ALOFT TOMORROW...AND THIS SHOULD FURTHER LIMIT
STORM CHANCES BY SUNDAY AFTERNOON THOUGH A ROGUE SHOWER/STORM CAN
NOT BE COMPLETELY RULED OUT. WE DID MAINTAIN A MINIMAL STORM MENTION
ACROSS THE FAR SOUTHERN ZONES WHERE THERE IS SOME INDICATION A
CONVERGENT SURFACE BOUNDARY COULD BE PRESENT AND LOCALLY ENHANCE CI
CHANCES. OTHERWISE...IT WILL BE YET ANOTHER MILD NIGHT TONIGHT AND
HOT DAY TOMORROW WITH TEMPERATURES REMAINING SLIGHTLY ABOVE
MID-AUGUST AVERAGES.

LONG TERM...
THE FCST AREA WILL BE ON THE WRN END OF THE BERMUDA HIGH THROUGH
NEXT WEEK AS A TROUGH DEVELOPS OVER THE WRN CONUS. MODELS HAVING
SOME TROUBLE RESOLVING THE EVOLUTION OF THE TROUGH...SO FCST
BECOMES MORE UNCERTAIN TOWARD THE LATTER PART OF THE WEEK AS
POTENTIAL EXISTS TO BRING SOME NOCTURNAL CONVECTION INTO THE WRN
ZONES. HOWEVER...WILL LEAVE THAT MENTION OUT UNTIL PICTURE BECOMES
CLEARER. OTHERWISE...SEASONALLY WARM WITH TEMPS AT OR JUST BELOW
MOS. MODELS CONTINUE TO DRY THE MID LEVELS EARLY IN THE WEEK...
AND FOR THE MOST PART KEEP THEM THAT WAY. SOME INDICATION THAT
SOME DEEPER MOISTURE COULD MIGRATE NWD INTO THE FCST AREA TOWARD
WEDNESDAY WITH AN OUTSIDE CHANCE OF SOME SHOWERS. MORE LIKELY
OUTCOME IS SOME INCREASE IN CLOUD COVER AND SUBTLE DOWNWARD TREND
TO DAYTIME TEMPS.

.AVIATION...
VFR CONDITIONS EXPECTED NEXT 24HRS. CONVECTION THIS EVENING

SHORT TERM...
BIGGEST CHALLENGE TODAY IS QUANTIFYING STORM CHANCES OVER THE NEXT
24 HOURS WITHIN WEAKLY FORCED FLOW...THOUGH AN OVERALL DOWNWARD
TREND IN COVERAGE IS EXPECTED FROM YESTERDAY.

EARLY AFTERNOON WATER VAPOR IMAGERY SHOWS THAT THE MONSOONAL
MOISTURE PLUME WAS CONTINUING TO BEND MORE EASTWARD FROM SOUTHERN
NEW MEXICO AND FAR WEST TEXAS THROUGH MUCH OF OKLAHOMA AND NORTH
TEXAS...INCLUDING OVER THE SOUTH PLAINS. HOWEVER...THE RICHEST
TROPOSPHERIC MOISTURE HAS SHIFTED JUST TO THE SOUTH AND EAST OF THE
CWA BEHIND A WEAK EMBEDDED MID-LEVEL SHORTWAVE TROUGH...THOUGH
ANOTHER POCKET OF REMNANT RICHER MID-LEVEL MOISTURE IS IN PLACE
ACROSS THE WESTERN OKLAHOMA AND TEXAS PANHANDLES. ALOFT...THE
MID-LEVEL STEERING FLOW HAS TURNED MORE NORTH-TO-SOUTH BEHIND THE
WEAK DEPARTING SHORTWAVE AND DOWNSTREAM OF THE EXPANSIVE
SOUTHWESTERN HIGH. AT THE SURFACE...A RATHER WEAK AND SOMEWHAT
ERRATIC WIND FIELD WAS IN PLACE WITH A WEAK PRESSURE GRADIENT OVER
THE SOUTH PLAINS REGION. SURFACE MOISTURE WAS HOLDING IN PLACE WITH
DEWPOINTS FROM THE MIDDLE 50S TO LOWER 60S COMMON AND COUPLED WITH
STRONG HEATING...THIS WAS YIELDING MODEST INSTABILITY AND WEAKENING
CONVECTIVE INHIBITION. THIS ENVIRONMENT COULD SUPPORT AN ISOLATED
THUNDERSTORM ALMOST ANYWHERE AS WE HEAD THROUGH PEAK HEATING. THAT
SAID...CONVECTIVE ACTIVITY CURRENTLY DEVELOPING ACROSS THE WESTERN
PANHANDLES AND NORTHEAST AND EAST-CENTRAL NEW MEXICO WILL LIKELY
BRING THE BEST SHOT OF STORMS TO AFFECT THE FA LATE THIS AFTERNOON
AND THIS EVENING AS THEY TRACK SOUTHWARD AND SOUTHEASTWARD.
HENCE...WE HAVE MAINTAINED A SCATTERED THUNDERSTORM MENTION ACROSS
MOST OF THE WESTERN ZONES THROUGH THIS EVENING. ANOTHER POSSIBLE
FOCUS FOR CONVECTIVE DEVELOPMENT WILL BE IN THE ROLLING PLAINS WHERE
SOUTHERLY BREEZES IMPINGE UPON THE LIGHT WIND FIELD TO THE NORTH.
RESPECTABLE PWATS IN EXCESS OF 1.2 INCHES AND SLOW STORM MOTIONS
WILL AGAIN SUPPORT A LOCALLY HEAVY RAIN THREAT WHILE A HOT AND
DEEPLY MIXED BOUNDARY LAYER WILL FAVOR GUSTY OUTFLOWS WITH THE
STRONGER STORMS. ANY ACTIVITY WILL GRADUALLY DECREASE AND SHIFT

.AVIATION...
THERE WILL BE A SLIM CHANCE OF A THUNDERSTORM AFFECTING THE
TERMINALS LATER THIS AFTERNOON INTO THIS EVENING...THOUGH
CONFIDENCE OF A DIRECT IMPACT IS TOO LOW TO INCLUDE EXPLICITLY.
OUTSIDE OF ANY THUNDERSTORM IMPACTS VFR CONDITIONS WILL PREVAIL
ALONG WITH LIGHT...THOUGH SOMEWHAT VARIABLE...WINDS.

&&

.PREV DISCUSSION... /ISSUED 1102 AM CDT SAT AUG 16 2014/

UPDATE...
WE HAVE COMPLETED A MINOR UPDATE TO ADJUST SEVERAL OF THE GRIDDED
FIELDS TO BETTER REFLECT THE CURRENT OBSERVATIONS AND TRENDS.
LIGHT BUT SOMEWHAT CHAOTIC SURFACE WINDS /MOSTLY WESTERLY TO
NORTHERLY/ WERE IN PLACE AS OF 15Z...IN THE WAKE OF A GOOD SURGE
OF MONSOONAL MOISTURE THAT WAS NOW SHIFTING JUST TO THE SOUTH AND
SOUTHEAST OF THE CWA. THIS MOISTURE AND AN EMBEDDED DISTURBANCE
WAS GENERATING A FEW SHOWERS AND AN OCCASIONAL ISOLATED STORM
ARCHING FROM WESTERN NORTH TEXAS INTO THE NORTHERN PERMIAN
BASIN...WITH A LIGHT DIMINISHING BAND OF ELEVATED SHOWERS ALSO
NOTED ACROSS THE FAR SOUTHWEST SOUTH PLAINS...ASSOCIATED WITH
CONVERGENT 850 MB FLOW. IT APPEARS THE BEST CHANCE OF SHOWERS
THROUGH THE REMAINDER OF THE MORNING AND EARLY AFTERNOON WILL
RESIDE OUTSIDE OF THE FA TO THE SOUTH AND EAST AS WELL AS TO THE
NORTH. HOWEVER...WE DID MAINTAIN A SLIM SHOWER MENTION FOR MUCH OF
THE PERIPHERY OF THE CWA THROUGH THE REMAINDER OF THE MORNING.

THE QUESTION THEN BECOMES WHERE WILL RENEWED AFTERNOON AND EVENING
CONVECTION FIRE? IT APPEARS A WEAKLY CONVERGENT SURFACE
TROUGH/BOUNDARY WILL LIKELY SETUP SOMEWHERE NEAR OR IN OUR
SOUTHEASTERN ZONES...AND THIS COULD BE THE FOCUS FOR ISOLATED
DEVELOPMENT. IN ADDITION...SCATTERED CONVECTION IS EXPECTED TO
FIRE ACROSS THE HIGHER TERRAIN OF NORTHEAST NM AS WELL AS THE
WESTERN OK/TX PANHANDLES /AIDED BY A CONVECTIVELY ENHANCED MID-
LEVEL DISTURBANCE/. THIS CONVECTION WILL BE DIRECTED SOUTHWARD AND
WILL AFFECT OUR WESTERN ZONES THROUGH THE EVENING HOURS. PWATS
WILL BE DOWN SOMEWHAT FROM YESTERDAY...THOUGH STILL RESPECTABLE
AOA 1 INCH...AND COULD SUPPORT A FEW LOCALLY HEAVY DOWNPOURS. IN
ADDITION...A HOT AND DEEPLY MIXED BOUNDARY LAYER WILL FAVOR GUSTY
OUTFLOWS WITH ANY STRONGER PRECIPITATION CORES. WE DID RECONFIGURE
POPS SLIGHTLY...WHILE MAINTAINING A SCATTERED MENTION ACROSS THE
NORTHWEST/WESTERN ZONES THIS AFTERNOON/EVENING...WITH A SLIGHT
CHANCE OVER THE REMAINDER OF THE FA WHERE FORCING IS LESS CERTAIN.

PREV DISCUSSION... /ISSUED 325 AM CDT SAT AUG 16 2014/

SHORT TERM...
SHOWERS AND THUNDERSTORMS THIS MORNING ARE SLOWLY DISSIPATING AS
THEY PROGRESS EASTWARD ACROSS THE SOUTH PLAINS AND THE ROLLING
PLAINS. SOME SHOWERS ACROSS SOUTHEASTERN NM MAY MAKE THEIR WAY INTO
OUR SOUTHWESTERN ZONES EARLY THIS MORNING...HOWEVER ADDITIONAL
RAINFALL AMOUNTS SHOULD BE LIGHT. MORE CHANCES FOR RAIN WILL COME
AGAIN LATER THIS AFTERNOON AND EVENING AS ANOTHER SHORTWAVE MOVES
AROUND THE UPPER LEVEL HIGH THAT IS CURRENTLY TO OUR WEST. SHOWER
COVERAGE WITH THIS SHORTWAVE WILL BE LESS THAN LAST NIGHT AS THE
BULK OF THE ENERGY WITH THE WAVE WILL BE JUST TO OUR WEST. THE BEST
COVERAGE CHANCES WILL BE ALONG THE TX/NM STATE LINE. ISOLATED SHOWER
AND THUNDERSTORM ACTIVITY WILL BE POSSIBLE ELSEWHERE ACROSS THE FA
AS A LINGERING SURFACE TROF STAYS IN THE AREA. ACTIVITY WITH THIS
WILL MOST LIKELY BE LIMITED DUE TO LACK OF STRONG UPPER LEVEL LIFT
WHICH IS DISPLACED TO THE WEST. SHOWER ACTIVITY WILL DECREASE OVER
NIGHT INTO TOMORROW MORNING AS THE SHORTWAVE MOVES AWAY FROM THE
AREA. TEMPERATURES TODAY SHOULD BE SIMILAR TO THAT OF YESTERDAY
AVERAGING AROUND THE MID 90S ON THE CAPROCK WITH UPPER 90S TO NEAR
100 OFF THE CAPROCK.

LONG TERM...
NOT MUCH CHANGE ANTICIPATED THIS FCST PACKAGE AS UPPER HIGH
CONTINUES OUT NEAR THE FOUR CORNERS WITH A WEAKNESS IN THE RIDGE
ACROSS CENTRAL TEXAS THROUGH THE REMAINDER OF THE WEEKEND. IT
WOULD APPEAR THAT THE BEST RAIN CHANCES SHOULD REMAIN TO OUR SOUTH
AND SOUTHEAST LATE SUNDAY INTO MONDAY.  TROUGH DIGS ALONG THE WEST
COAST EARLY NEXT WEEK WHILST UPPER HIGH SLOWLY MOVES BACK IN OUR
DIRECTION. THIS SCENARIO LOOKS A BIT MORE CLEAR THAN LAST NIGHT
THOUGH BEYOND TUESDAY SOLUTIONS DIFFER AS THE ECM EJECTS THE
SYSTEM TO OUR NORTH WHEREAS THE GFS HANGS IT OUT WEST.
NEVERTHELESS...WILL CONTINUE TRENDS OF DRYING THINGS NEXT WEEK
ALONG WITH SLOWLY INCREASING TEMPS. STORMS MAY APPROACH OUR
WESTERN ZONES LATE NEXT WEEK BUT WILL KEEP POPS SILENT FOR NOW AS
DYNAMICS REMAIN QUITE WEAK WITH HIGH MODEL SPREAD.

AGAIN LATER THIS AFTERNOON AND EVENING AS ANOTHER SHORTWAVE MOVES
AROUND THE UPPER LEVEL HIGH THAT IS CURRENTLY TO OUR WEST. SHOWER
COVERAGE WITH THIS SHORTWAVE WILL BE LESS THAN LAST NIGHT AS THE

COVERAGE CHANCES WILL BE ALONG THE TX/NM STATE LINE. ISOLATED SHOWER

NOT MUCH CHANGE ANTICIPATED THIS FCST PACKAGE AS UPPER HIGH

THUNDERSTORM CHANCES WILL QUICKLY DWINDLE OVER THE NEXT HOUR BUT
RAIN SHOWERS WILL LIKELY PERSIST FOR SEVERAL HOURS AT BOTH TAF
SITES. ADDITIONAL THUNDERSTORM DEVELOPMENT MAY BE POSSIBLE AGAIN
SATURDAY EVENING AT EITHER TAF SITE BUT CONFIDENCE IS TOO LOW TO
MENTION IN THE TAF AT THE MOMENT.

PREV DISCUSSION... /ISSUED 303 PM CDT FRI AUG 15 2014/

SHORT TERM...
THE PRIMARY FOCUS IN THE SHORT TERM REVOLVES AROUND IMPROVING
THUNDERSTORM CHANCES THROUGH TONIGHT...WITH LINGERING CHANCES
PERSISTING INTO SATURDAY.

SEVERAL UPPER LEVEL LEVEL DISTURBANCES EMERGING EASTWARD ACROSS THE
CENTRAL AND NORTHERN PLAINS HAVE HELPED TO SUPRESS THE NORTHEASTERN
PERIPHERY OF THE UPPER RIDGE THAT HAS EXERTED A STRONG INFLUENCE ON
THE SOUTH PLAINS THE LAST FEW DAYS AND PROVIDED DRY WEATHER. THIS
MODEST PATTERN SHIFT HAS ALLOWED THE MID/UPPER LEVEL MONSOONAL
MOISTURE PLUME TO SHIFT EASTWARD...WITH THE 18Z SATELLITE DERIVED
TOTAL PRECIPITABLE WATER PRODUCT SHOWING VALUES OF 100-120 PERCENT
OF NORMAL NOW SPILLING ACROSS ROUGHLY THE NORTHWEST HALF OF THE CWA.
THE IMPROVED MOISTURE ALOFT...COUPLED WITH A SURFACE LEE TROUGH THAT
HAS ALSO BEEN DRAGGED EASTWARD AND WAS TRAILING FROM THE CENTRAL
TEXAS PANHANDLE SOUTHWESTWARD INTO FAR SOUTHEAST NEW MEXICO...WILL
LIKELY BE ENOUGH TO GENERATE ISOLATED TO SCATTERED THUNDERSTORMS
THROUGH THE LATE AFTERNOON HOURS. IN FACT...A FEW SHOWERS WERE
ALREADY NOTED DEVELOPING JUST EAST OF LAZBUDDIE TO MULESHOE LINE AS
OF 1940Z. THIS ACTIVITY WAS DEVELOPING IN AN ATMOSPHERE
CHARACTERIZED BY RELATIVELY HIGH PWATS /NEAR 1.4 INCHES/...MODEST
INSTABILITY /MLCAPES AOB 1000 J/KG/...WEAK WIND SHEAR AND RATHER
LIGHT STEERING FLOW. THUS...DO NOT EXPECT MUCH ORGANIZATION TO THE
ACTIVITY...THOUGH THE SLOW STORM MOTIONS COUPLED WITH THE ABUNDANT
MID/UPPER LEVEL MOISTURE COULD SUPPORT LOCALLY HEAVY RAINFALL.
ADDITIONALLY...DEWPOINT DEPRESSIONS OF 30-40 DEGREES ALONG WITH A
DEEPLY MIXED BOUNDARY LAYER COULD SUPPORT STRONG WIND GUSTS WITH THE
MORE INTENSE PRECIPITATION CORES. THIS ACTIVITY WILL TRACK
EASTWARD...THOUGH THE EASTWARD EXTENT MAY BE THWARTED SOMEWHAT AS IT
ADVANCES OUT OF THE THETAE RIDGE AXIS AND ENCOUNTERS A LESS
FAVORABLE THERMODYNAMIC ENVIRONMENT. MOST NWP SUGGEST THE BULK OF THE
CONVECTION WILL STAY ALONG AND WEST OF A QUITAQUE TO LUBBOCK TO NEW
MOORE LINE THROUGH LATE THIS EVENING. IN ADDITION...MORE WIDESPREAD
CONVECTION CURRENTLY DEVELOPING OVER THE HIGHER TERRAIN OF EASTERN
NEW MEXICO MAY ATTEMPT TO ORGANIZE INTO A SMALL MCS AND TRANSLATE
SOUTHEASTWARD THIS EVENING...WHICH COULD FURTHER ENHANCE STORM
CHANCES FOR MANY SPOTS ON THE CAPROCK WELL INTO THE EVENING HOURS.

THE BEST UPPER LEVEL MOISTURE...ALONG WITH A POSSIBLE CONVECTIVELY
ENHANCED EMBEDDED DISTURBANCE...WILL THEN SAG SOUTHEASTWARD OVER THE
AREA THROUGH THE LATE NIGHT HOURS AND INTO SATURDAY. THIS MAY KEEP
AT LEAST LOW SHOWER/STORM CHANCES GOING THROUGH MUCH OF THE NIGHT
WHILE ALSO EXPANDING TO INCLUDE MUCH OF THE REMAINDER OF THE FA.
THERE IS SOME CONCERN CLOUD COVER AND POSSIBLE SHOWERS COULD LINGER
ACROSS THE SOUTHEASTERN ZONES WELL INTO THE DAY ON SATURDAY. IF THIS
DOES HAPPEN IT WOULD BOTH KEEP TEMPERATURES DOWN FROM WHAT ARE
CURRENTLY FORECAST AS WELL AS LIMIT RENEWED AFTERNOON CONVECTIVE
DEVELOPMENT IN THIS AREA. CONFIDENCE IN THIS IS NOT OVERLY
HIGH...THOUGH WE DID TRIM FORECAST HIGHS DOWN SLIGHTLY. A SURFACE
TROUGH WILL AGAIN BE SITUATED ACROSS THE AREA TOMORROW
AFTERNOON...LIKELY DISPLACED A LITTLE FURTHER SOUTH THAN TODAY. IN
ADDITION...ANY RESIDUAL OUTFLOWS ALONG WITH ANOTHER POSSIBLE UPPER
LEVEL DISTURBANCE APPROACHING FROM THE NORTHWEST WILL KEEP AT LEAST
A CHANCE OF STORMS IN THE FORECAST FOR THE ENTIRE AREA TOMORROW
AFTERNOON...THOUGH HOW TONIGHT/S ACTIVITY PLAYS OUT WILL HELP
DICTATE THE DETAILS.

IT WILL BE ANOTHER MILD NIGHT TONIGHT WITH LOWS IN THE MIDDLE 60S TO
LOWER 70S ON THE CAPROCK...AND LOW TO MIDDLE 70S COMMON IN THE
ROLLING PLAINS. HIGHS SATURDAY WILL BE MOSTLY IN THE 90S.

LONG TERM...
RAIN CHANCES NOT LOOKING AS GOOD LATE WEEKEND INTO EARLY WORK WEEK
AS A MID/UPPER LEVEL LOW MOVES SWD TO THE PERMIAN BASIN BY SUNDAY.
AS A RESULT WILL SEE BETTER RAIN CHANCES BEGIN TO SHIFT TO TRANS
PECOS...PERMIAN BASIN AND CONCHO VALLEY FOR SUNDAY AFTN. WILL HOLD
ONTO SOME SLIGHT CHC POPS EXTREME SRN ZONES THROUGH SUNDAY WITH
POSSIBILITY OF THE LOW MOVING SLOWER THAN CURRENTLY PROGGED. MID
AND UPPER LEVELS PROGGED TO BEGIN DRYING MONDAY WITH DEEPER
MOISTURE ROTATING NWD AROUND THE FCST AREA FROM NM NEWD TO THE
CNTL HIGH PLAINS WHERE IT GETS PICKED UP BY STRONGER WESTERLIES
ALOFT. AS A RESULT APPEARS UPCOMING WEEK DOMINATED BY VERY LIMITED

THE BIGGEST CONCERN THIS TAF CYCLE REVOLVES AROUND THUNDERSTORM
CHANCES AT THE TERMINALS. IT APPEARS LBB MAY HAVE A SOMEWHAT
BETTER SHOT THAN CDS TO EXPERIENCE CONVECTION FROM LATE THIS
AFTERNOON INTO TONIGHT...BUT OVERALL CONFIDENCE IN A DIRECT IMPACT
IS STILL A LITTLE TOO LOW TO INCLUDE EXPLICITLY IN THE TAFS...WITH
THE BEST STORM CHANCES RESIDING TO THE WEST OF THE TERMINALS.
HOWEVER...WE DID INCLUDE A VCTS REMARK AT LBB FROM 22Z WELL INTO
THE EVENING. OBVIOUSLY CONVECTIVE TRENDS WILL HAVE TO BE
MONITORED CLOSELY AND AMENDMENTS WILL BE POSSIBLE WITH SUB-VFR
CONDITIONS AND STRONG AND ERRATIC WINDS POSSIBLE NEAR ANY STORMS.

EVENING. LATEST HIGH-RESOLUTION AND SHORT-RANGE NWP CONTINUE TO
FAVOR CONVECTIVE INITIATION BY MID/LATE AFTERNOON ALONG/NEAR A
SURFACE TROUGH THAT WILL STRETCH FROM THE CENTRAL PANHANDLE INTO
FAR SOUTHEAST NEW MEXICO. THIS WILL OCCUR WITHIN A MID/UPPER LEVEL
MONSOONAL MOISTURE PLUME THAT WAS NOW SHIFTING EASTWARD OVER THE
SOUTH PLAINS REGION...SEEN VISUALIZED IN SATELLITE AND RAOB DATA.
PWATS ARE PROGGED TO PEAK NEAR 1.5 INCHES ACROSS THE NORTHWESTERN
HALF OF THE CWA BY LATE TODAY...BEFORE THE DEEPEST MOISTURE SLOWLY
SHIFTS SOUTHEASTWARD THROUGH SATURDAY. THIS INCREASED TROPOSPHERIC
MOISTURE ALONG WITH RATHER WEAK STEERING FLOW /AND SLOW STORM
MOTIONS/ COULD SUPPORT A FEW LOCALLY HEAVY DOWNPOURS FOR THOSE
LUCKY ENOUGH TO GET UNDER ANY STRONGER CELLS. IN ADDITION...A
DEEPLY MIXED BOUNDARY LAYER AND RELATIVELY HIGH CLOUD BASES COULD
SUPPORT HYBRID-TYPE MICROBURSTS RESULTING IN STRONG WINDS WITH THE
MOST INTENSE STORMS THIS AFTERNOON INTO THIS EVENING. GIVEN
THIS...WE HAVE UPDATED THE HWO TO INCLUDE A MENTION OF LOCALLY
HEAVY RAIN AND GUSTY WINDS THIS AFTERNOON/EVENING. THE ACTIVITY
MAY EVEN TRY TO CONGEAL INTO A WEAKLY ORGANIZED MCS THIS EVENING
AS IT TRANSLATES SLOWLY TO THE SOUTH AND EAST...THOUGH A LESS
FAVORABLE THERMODYNAMIC ENVIRONMENT MAY TEND TO LIMIT ITS EASTWARD
EXPANSE. OVERALL...ONLY MINOR ADJUSTMENTS MADE TO EXPAND THE
SLIGHT CHANCE AND CHANCE POPS A LITTLE EASTWARD...BUT STILL
FAVORING THE NORTHWEST HALF OF THE CWA. SOME ISOLATED ELEVATED
ACTIVITY COULD LINGER WELL INTO THE NIGHT OR EVEN EARLY SATURDAY
AS THE RICH MID/UPPER LEVEL MOISTURE REMAINS ANCHORED OVER THE AREA
AND COUPLES WITH A POSSIBLE WEAK EMBEDDED MID-LEVEL DISTURBANCE
AND A MODEST SOUTHERLY LOW-LEVEL JET.

EARLY MORNING WV IMAGERY SHOWS CONVECTION OVER NM TAPERING OFF WITH
JUST A FEW SHOWERS LINGERING OVER THE MOUNTAINS. THE SHORTWAVE THAT
HELPED TRIGGER THIS CONVECTION IS MAKING ITS WAY EASTWARD AROUND A
593 HIGH. THIS SHORTWAVE WILL MOVE INTO THE REGION BY LATER THIS
AFTERNOON. THIS ALONG WITH AN ALREADY PRESENT LEE TROF WILL HELP
DEVELOP CONVECTION ACROSS OUR NORTHWESTERN ZONES BY THE LATE
AFTERNOON/EARLY EVENING. MODELS ARE IN FAIRLY GOOD AGREEMENT WITH
CONVECTION DEVELOPING INTO A WEAK MCS ALONG A SURFACE THETA E
AXIS ASSOCIATED WITH A SURFACE TROF AND SLOWLY PROGRESS IT
SOUTHEASTWARD THROUGH THE EVENING INTO THE EARLY NIGHT HOURS. WEAK
UPPER LEVEL FLOW ASSOCIATED WITH THE HIGH SHOULD PREVENT A FAST
MOVING MCS. THESE SHOWERS AND THUNDERSTORMS HAVE THE LIKELIHOOD TO
PRODUCE MODERATE RAINFALL AS PWATS WILL BE HIGH...AROUND 1.5
INCHES.

WHILE CONVECTIVE ACTIVITY SHOULD DIMINISH OVERNIGHT...MODELS HINT AT
A SMALL COMPLEX LINGERING INTO THE EARLY MORNING ACROSS THE SOUTHERN
SOUTH PLAINS...POSSIBLY A PRODUCT OF OUTFLOW FROM EARLIER STORMS

1152 PM CDT THU AUG 14 2014

.AVIATION...
THUNDERSTORMS ARE EXPECTED TO DEVELOP NORTHWEST OF THE KLBB
TERMINAL THIS AFTERNOON BUT VERY SLOW MOVEMENT TO THESE STORMS IS
EXPECTED. THEREFORE...UNCERTAINTY REMAINS HIGH IF ANY STORMS WILL
IMPACT THE KLBB TERMINAL THIS AFTERNOON AND EARLY EVENING.
OTHERWISE...VFR WILL PREVAIL.

&&

PREV DISCUSSION... /ISSUED 302 PM CDT THU AUG 14 2014/

SHORT TERM...
NARROW AXIS OF TSTORMS PRESENTLY UNDERWAY FROM THE SACRAMENTOS TO
NEAR SANTA ROSA/NM ARE EXPECTED TO FALL SHORT OF OUR AREA LATER
TODAY DUE TO LITTLE IN THE WAY OF PROPAGATION POTENTIAL INTO AN
INCREASINGLY HOSTILE ENVIRONMENT DOMINATED BY AN UPPER RIDGE.

EFFECTS OF THIS RIDGE WILL BE ON THE DECLINE OVERNIGHT AND
ESPECIALLY FRIDAY AS THE SUBTROPICAL HIGH ASSUMES A MORE WESTERLY
LONGITUDE. THIS PROCESS IS IN RESPONSE TO A SHORTWAVE TROUGH
/CURRENTLY NEAR THE COLORADO PLATEAU/ THAT WILL TRACK SLOWLY E-SE
AND GARNER WEAKLY CYCLONIC NORTHWEST FLOW FOR THE SOUTH PLAINS ON
FRIDAY. MODELS ARE OPTIMISTIC IN SHIFTING A PORTION OF THE MID/UPPER
LEVEL MONSOONAL MOISTURE ACROSS A GOOD CHUNK OF THE CWA DURING THE
DAY...HOWEVER THE RICHEST PWATS ARE PROGGED TO RESIDE IN OUR NWRN
ZONES WHERE VALUES COULD REACH 1.5 INCHES. THIS REGION WILL ALSO BE
NEAR A DIFFUSE SURFACE TROUGH...BUT OVERALL LIFT IS OF THE TYPICAL
MUTED VARIETY FOR THIS TIME OF YEAR WITH ONLY A GLANCING BLOW
EXPECTED FROM THE AFOREMENTIONED S/W TROUGH AND A MEAGER 30 KNOT JET
MAX AT 300MB. NONETHELESS...DIURNAL HEATING COMBINED WITH THESE
FACTORS SHOULD SUPPORT AT LEAST SPOTTY PRECIP DEVELOPMENT FRI AFTN
IN OUR NW ZONES BEFORE OUTFLOWS AND WEAK NW STEERING FLOW EXPAND
THESE CHANCES OVER THE REMAINDER OF THE AREA AFTER 00Z.

ALTHOUGH THICKNESSES ARE SHOWN TO RISE A TOUCH BY TOMORROW...HAVE
KEPT MAX TEMPS ON THE COOLER SIDE OF MOS GIVEN PERIODS OF DENSE
CIRRUS SPILLING AROUND THE DEPARTING HIGH.

LONG TERM...
UPPER RIDGING WILL BE CENTERED ACROSS THE DESERT SOUTHWEST THROUGH
MUCH OF ALL OF THE EXTENDED WITH THE SOUTH PLAINS REGION ON THE
EASTERN PERIPHERY OF THIS RIDGING. THIS SHOULD SECURE A RATHER
TYPICAL WARM STRETCH OF MID-AUGUST WEATHER...WITH HIGHS GENERALLY
PEAKING A FEW DEGREES ABOVE AVERAGE...PERHAPS GRADUALLY DECREASING
TOWARD AVERAGE BY THE END OF THE LONG TERM.

AT LEAST LOW STORM CHANCES WILL LINGER IN THE FORECAST THIS WEEKEND
AS ANY RESIDUAL OUTFLOW BOUNDARIES FROM FRIDAY/S CONVECTION COMBINE
WITH WHAT REMAINS OF THE MONSOONAL MOISTURE PLUME. IN ADDITION...A
COUPLE OF WEAK/SUBTLE EMBEDDED UPPER LEVEL DISTURBANCES COULD PROVIDE
A LITTLE LIFT AS THEY ROUND THE EASTERN SIDE OF THE RIDGE. ALSO...A
WEAK FRONT WILL MOVE INTO THE PLAINS...THOUGH IT STILL APPEARS THIS
FRONT WILL STALL TO OUR NORTH BEFORE RETREATING BACK NORTH. THINGS
BECOME LESS CLEAR NEXT WEEK AS THE MEDIUM RANGE MODELS ADVERTISE A
MID-LEVEL WEAKNESS DEVELOPING AND PERSISTING SOMEWHERE OVER THE
LONE STAR STATE. THE ECMWF FAVORS A FURTHER WEST POSITION FOR THIS
WEAKNESS WHICH WOULD KEEP AT LEAST LOW THUNDER CHANCES IN THE
FORECAST THOUGH MUCH OF NEXT WEEK. HOWEVER...THE GFS AND DGEX KEEP
THE WEAKNESS TO OUR EAST WITH A GREATER INFLUENCE FROM THE EASTERN
EXTENT OF THE UPPER HIGH...THUS KEEPING THE SOUTH PLAINS GENERALLY
DRY. GIVEN THE DIFFERENCES...WE HAVE DECIDED NOT TO MAKE ANY
CHANGES TO THE POP/WX FIELDS FOR NEXT WEEK UNTIL THINGS COME INTO
BETTER AGREEMENT.

THUNDERSTORMS COULD THREATEN TO AFFECT THE KLBB TERMINAL NEAR THE
END OF THIS TAF PERIOD BUT CONFIDENCE IS TOO LOW TO MENTION AT THE

SHORT TERM...
NARROW AXIS OF TSTORMS PRESENTLY UNDERWAY FROM THE SACRAMENTOS TO
NEAR SANTA ROSA/NM ARE EXPECTED TO FALL SHORT OF OUR AREA LATER
TODAY DUE TO LITTLE IN THE WAY OF PROPAGATION POTENTIAL INTO AN
INCREASINGLY HOSTILE ENVIRONMENT DOMINATED BY AN UPPER RIDGE.

EFFECTS OF THIS RIDGE WILL BE ON THE DECLINE OVERNIGHT AND
ESPECIALLY FRIDAY AS THE SUBTROPICAL HIGH ASSUMES A MORE WESTERLY
LONGITUDE. THIS PROCESS IS IN RESPONSE TO A SHORTWAVE TROUGH
/CURRENTLY NEAR THE COLORADO PLATEAU/ THAT WILL TRACK SLOWLY E-SE
AND GARNER WEAKLY CYCLONIC NORTHWEST FLOW FOR THE SOUTH PLAINS ON
FRIDAY. MODELS ARE OPTIMISTIC IN SHIFTING A PORTION OF THE MID/UPPER
LEVEL MONSOONAL MOISTURE ACROSS A GOOD CHUNK OF THE CWA DURING THE
DAY...HOWEVER THE RICHEST PWATS ARE PROGGED TO RESIDE IN OUR NWRN
ZONES WHERE VALUES COULD REACH 1.5 INCHES. THIS REGION WILL ALSO BE
NEAR A DIFFUSE SURFACE TROUGH...BUT OVERALL LIFT IS OF THE TYPICAL
MUTED VARIETY FOR THIS TIME OF YEAR WITH ONLY A GLANCING BLOW
EXPECTED FROM THE AFOREMENTIONED S/W TROUGH AND A MEAGER 30 KNOT JET
MAX AT 300MB. NONETHELESS...DIURNAL HEATING COMBINED WITH THESE
FACTORS SHOULD SUPPORT AT LEAST SPOTTY PRECIP DEVELOPMENT FRI AFTN
IN OUR NW ZONES BEFORE OUTFLOWS AND WEAK NW STEERING FLOW EXPAND
THESE CHANCES OVER THE REMAINDER OF THE AREA AFTER 00Z.

ALTHOUGH THICKNESSES ARE SHOWN TO RISE A TOUCH BY TOMORROW...HAVE
KEPT MAX TEMPS ON THE COOLER SIDE OF MOS GIVEN PERIODS OF DENSE
CIRRUS SPILLING AROUND THE DEPARTING HIGH.

LONG TERM...
UPPER RIDGING WILL BE CENTERED ACROSS THE DESERT SOUTHWEST THROUGH
MUCH OF ALL OF THE EXTENDED WITH THE SOUTH PLAINS REGION ON THE
EASTERN PERIPHERY OF THIS RIDGING. THIS SHOULD SECURE A RATHER
TYPICAL WARM STRETCH OF MID-AUGUST WEATHER...WITH HIGHS GENERALLY
PEAKING A FEW DEGREES ABOVE AVERAGE...PERHAPS GRADUALLY DECREASING
TOWARD AVERAGE BY THE END OF THE LONG TERM.

AT LEAST LOW STORM CHANCES WILL LINGER IN THE FORECAST THIS WEEKEND
AS ANY RESIDUAL OUTFLOW BOUNDARIES FROM FRIDAY/S CONVECTION COMBINE
WITH WHAT REMAINS OF THE MONSOONAL MOISTURE PLUME. IN ADDITION...A
COUPLE OF WEAK/SUBTLE EMBEDDED UPPER LEVEL DISTURBANCES COULD PROVIDE
A LITTLE LIFT AS THEY ROUND THE EASTERN SIDE OF THE RIDGE. ALSO...A
WEAK FRONT WILL MOVE INTO THE PLAINS...THOUGH IT STILL APPEARS THIS
FRONT WILL STALL TO OUR NORTH BEFORE RETREATING BACK NORTH. THINGS
BECOME LESS CLEAR NEXT WEEK AS THE MEDIUM RANGE MODELS ADVERTISE A
MID-LEVEL WEAKNESS DEVELOPING AND PERSISTING SOMEWHERE OVER THE
LONE STAR STATE. THE ECMWF FAVORS A FURTHER WEST POSITION FOR THIS
WEAKNESS WHICH WOULD KEEP AT LEAST LOW THUNDER CHANCES IN THE
FORECAST THOUGH MUCH OF NEXT WEEK. HOWEVER...THE GFS AND DGEX KEEP
THE WEAKNESS TO OUR EAST WITH A GREATER INFLUENCE FROM THE EASTERN

PREV DISCUSSION... /ISSUED 254 PM CDT WED AUG 13 2014/

SHORT TERM...
UPPER LEVEL HIGH PRESSURE RIDGE WILL REMAIN ACROSS WEST TEXAS
THROUGH THURSDAY. SUBSIDENCE WARMING EVIDENT IN CURRENT AND FORECAST
SOUNDINGS IN 700-400 MB LAYER WILL PREVENT INITIATION OF DEEP MOIST
CONVECTION. SHORTWAVE TROF WILL MOVE NORTHEASTWARD FROM UTAH LATE
TODAY INTO WYOMING BY THURSDAY AFTERNOON. THE EFFECT ACROSS OUR
REGION WILL BE A SLIGHTLY DEEPENING SURFACE LOW PRESSURE TROF FROM
THE CENTRAL HIGH PLAINS INTO WEST TEXAS...AN ASSOCIATED VERY SLIGHT
UPTICK IN SURFACE WINDS AND A 25-30 KNOT S/SW LOW LEVEL JET EARLY
THUR ACROSS THE WESTERN SOUTH PLAINS INTO THE PANHANDLE. MOS TEMPS
ON TRACK AND ACCEPTED WITH MINOR ADJUSTMENTS. JAMES

LONG TERM...
UPPER RIDGING WILL PROVIDE TEMPERATURES ON THE HIGH SIDE OF AVERAGE
THROUGH MUCH OR ALL OF THE EXTENDED. HOWEVER...THE CENTER OF THE
UPPER HIGH WILL SHIFT FROM WEST TEXAS TODAY TO THE DESERT SOUTHWEST
LATE WEEK WHERE IT MAY REMAIN FOR THE REST OF THE LONG TERM. A
DISTURBANCE CURRENTLY LIFTING THROUGH THE FOUR CORNERS WILL PIVOT
AROUND THE NORTHERN PERIPHERY OF THE UPPER HIGH AND IN ADVANCE OF AN
UPPER LOW THAT WILL LINGER OVER THE PACIFIC NORTHWEST THROUGH
FRIDAY. THE NORTHWESTERN UPPER LOW WILL THEN GRADUALLY OPEN AND MOVE
EASTWARD ALONG THE CANADIAN BORDER THROUGH EARLY NEXT WEEK.

THE LEAD PASSING SHORTWAVE TROUGH WILL HELP DRAW A THINNING PLUME
OF MONSOONAL MOISTURE OVER THE SOUTH PLAINS REGION FRIDAY INTO
SATURDAY. ALTHOUGH THE PRIMARY LIFT WITH THIS INITIAL WAVE WILL BE
WELL TO THE NORTH THERE COULD BE A LITTLE EMBEDDED SUPPORT WITHIN
THE MONSOONAL MOISTURE PLUME CLOSER TO HOME AND WHEN COUPLED WITH A
SURFACE TROUGH SHIFTING EASTWARD OUT OF NEW MEXICO...IT COULD
SUPPORT ISOLATED TO SCATTERED CONVECTIVE DEVELOPMENT. THE BEST STORM
CHANCES WILL LIKELY BE CONFINED TO THE CAPROCK FRIDAY AFTERNOON AND
EARLY EVENING...BUT THEN WILL EXPAND TO INCLUDE THE ENTIRE AREA BY
LATE FRIDAY NIGHT INTO SATURDAY. THIS DIRTY RIDGE WILL THEN
PERSIST...IN SOME FORM OR ANOTHER...THOUGH MUCH OF THE REMAINDER OF
THE EXTENDED...THOUGH DETAILS IN THE SUBTLE FORCING IN THIS WEAK
FLOW REGIME REMAIN TOUGH TO PINPOINT. A WEAK COLD FRONT WILL FOLLOW
THE INITIAL SHORTWAVE PASSAGE SATURDAY...WITH A SECONDARY FRONT
MOVING DOWN THE PLAINS BEHIND THE WEAKENING UPPER LOW EARLY NEXT
WEEK. AT THIS POINT IT APPEARS BOTH FRONTAL SURGES MAY STALL JUST
SHORT OF THE CWA...THOUGH IF THEY CAN MAKE IT THIS FAR SOUTH THEY
COULD PROVIDE ADDITIONAL FOCI FOR CONVECTIVE INITIATION. FOR
NOW...WE HAVE EXPANDED THE SLIGHT CHANCE POPS THROUGH THE
WEEKEND...WITH SUB-MENTIONABLE 10-14 PERCENT POPS FOR THE REMAINDER
OF THE EXTENDED WHEN FORCING FOR ISOLATED TO SCATTERED CONVECTION IS
A LITTLE MORE UNCERTAIN.

SHORT TERM...
UPPER LEVEL HIGH PRESSURE RIDGE WILL REMAIN ACROSS WEST TEXAS
THROUGH THURSDAY. SUBSIDENCE WARMING EVIDENT IN CURRENT AND FORECAST
SOUNDINGS IN 700-400 MB LAYER WILL PREVENT INITIATION OF DEEP MOIST
CONVECTION. SHORTWAVE TROF WILL MOVE NORTHEASTWARD FROM UTAH LATE
TODAY INTO WYOMING BY THURSDAY AFTERNOON. THE EFFECT ACROSS OUR
REGION WILL BE A SLIGHTLY DEEPENING SURFACE LOW PRESSURE TROF FROM
THE CENTRAL HIGH PLAINS INTO WEST TEXAS...AN ASSOCIATED VERY SLIGHT
UPTICK IN SURFACE WINDS AND A 25-30 KNOT S/SW LOW LEVEL JET EARLY
THUR ACROSS THE WESTERN SOUTH PLAINS INTO THE PANHANDLE. MOS TEMPS
ON TRACK AND ACCEPTED WITH MINOR ADJUSTMENTS. JAMES

LONG TERM...
UPPER RIDGING WILL PROVIDE TEMPERATURES ON THE HIGH SIDE OF AVERAGE
THROUGH MUCH OR ALL OF THE EXTENDED. HOWEVER...THE CENTER OF THE
UPPER HIGH WILL SHIFT FROM WEST TEXAS TODAY TO THE DESERT SOUTHWEST
LATE WEEK WHERE IT MAY REMAIN FOR THE REST OF THE LONG TERM. A
DISTURBANCE CURRENTLY LIFTING THROUGH THE FOUR CORNERS WILL PIVOT
AROUND THE NORTHERN PERIPHERY OF THE UPPER HIGH AND IN ADVANCE OF AN
UPPER LOW THAT WILL LINGER OVER THE PACIFIC NORTHWEST THROUGH
FRIDAY. THE NORTHWESTERN UPPER LOW WILL THEN GRADUALLY OPEN AND MOVE
EASTWARD ALONG THE CANADIAN BORDER THROUGH EARLY NEXT WEEK.

THE LEAD PASSING SHORTWAVE TROUGH WILL HELP DRAW A THINNING PLUME
OF MONSOONAL MOISTURE OVER THE SOUTH PLAINS REGION FRIDAY INTO
SATURDAY. ALTHOUGH THE PRIMARY LIFT WITH THIS INITIAL WAVE WILL BE
WELL TO THE NORTH THERE COULD BE A LITTLE EMBEDDED SUPPORT WITHIN
THE MONSOONAL MOISTURE PLUME CLOSER TO HOME AND WHEN COUPLED WITH A
SURFACE TROUGH SHIFTING EASTWARD OUT OF NEW MEXICO...IT COULD
SUPPORT ISOLATED TO SCATTERED CONVECTIVE DEVELOPMENT. THE BEST STORM
CHANCES WILL LIKELY BE CONFINED TO THE CAPROCK FRIDAY AFTERNOON AND
EARLY EVENING...BUT THEN WILL EXPAND TO INCLUDE THE ENTIRE AREA BY
LATE FRIDAY NIGHT INTO SATURDAY. THIS DIRTY RIDGE WILL THEN
PERSIST...IN SOME FORM OR ANOTHER...THOUGH MUCH OF THE REMAINDER OF
THE EXTENDED...THOUGH DETAILS IN THE SUBTLE FORCING IN THIS WEAK
FLOW REGIME REMAIN TOUGH TO PINPOINT. A WEAK COLD FRONT WILL FOLLOW
THE INITIAL SHORTWAVE PASSAGE SATURDAY...WITH A SECONDARY FRONT
MOVING DOWN THE PLAINS BEHIND THE WEAKENING UPPER LOW EARLY NEXT
WEEK. AT THIS POINT IT APPEARS BOTH FRONTAL SURGES MAY STALL JUST
SHORT OF THE CWA...THOUGH IF THEY CAN MAKE IT THIS FAR SOUTH THEY
COULD PROVIDE ADDITIONAL FOCI FOR CONVECTIVE INITIATION. FOR
NOW...WE HAVE EXPANDED THE SLIGHT CHANCE POPS THROUGH THE
WEEKEND...WITH SUB-MENTIONABLE 10-14 PERCENT POPS FOR THE REMAINDER
OF THE EXTENDED WHEN FORCING FOR ISOLATED TO SCATTERED CONVECTION IS
A LITTLE MORE UNCERTAIN.
