AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
404 AM CDT FRI JUL 25 2014

.SHORT TERM...
UPPER LEVEL RIDGING WILL REMAIN IN CONTROL OF THE WEST TEXAS WEATHER
TODAY RESULTING IN THE CONTINUATION OF THE MID-SUMMER HEAT. A SLIGHT
UPTICK IN PROGGED 1000-500 MB THICKNESSES AND 850/700 MB
TEMPERATURES SUGGEST THAT HIGHS WILL BE A COUPLE DEGREES HIGHER THAN
ON THURSDAY FOR MOST SPOTS. AFTERNOON TEMPERATURES WILL PEAK IN THE
UPPER 90S TO AROUND 100 DEGREES ON THE CAPROCK...WITH 100 TO 104
DEGREES COMMON IN THE ROLLING PLAINS. AS HAS OCCURRED THE LAST
COUPLE OF DAYS...THIS HEAT AND RESIDUAL LOW-LEVEL MOISTURE COULD BE
ENOUGH TO FORCE AN EXTREMELY ISOLATED AND BRIEF LATE DAY
SHOWER...THOUGH COVERAGE AND DURATION WOULD BE VERY LOW...WITH POPS
UNDER 5 PERCENT AND MOSTLY SUNNY SKIES. ANOTHER WARM NIGHT WILL
FOLLOW TONIGHT WITH LOWS RANGING FROM THE UPPER 60S NORTHWEST TO
MIDDLE 70S EAST. THIS TOASTY PATTERN DOES RAISE CONCERN FOR HEAT
RELATED ILLNESSES...THOUGH IT APPEARS AFTERNOON HEAT INDICES WILL
GENERALLY REMAIN A COUPLE DEGREES SHY OF THE HEAT ADVISORY THRESHOLD
OF 105 DEGREES.

&&

.LONG TERM...
HOT TEMPERATURES WILL CONTINUE SATURDAY AND SUNDAY WITH GUIDANCE
PROGGING THE WARMEST MID-LEVEL TEMPS DURING THIS TIME. HIGHS WILL BE
NEAR TO SLIGHTLY ABOVE 100F FOR MOST LOCATIONS. ACROSS THE ROLLING
PLAINS...WHERE THE HIGHEST DEWPOINTS WILL BE FOUND...HEAT INDICES
ARE EXPECTED TO BE CLOSE OR SLIGHTLY BELOW THE AIR TEMP AND WE
DON/T EXPECT ANY EXCESSIVE HEAT HIGHLIGHTS AT THIS TIME. ON
SUNDAY...A VIGOROUS SHORTWAVE WILL DIVE OUT OF THE CENTRAL
CANADIAN PROVINCES INTO THE MIDWEST...DRAGGING A COLD FRONT SOUTH
THROUGH THE CENTRAL PLAINS. THE FRONT IS EXPECTED TO SPARK
SCATTERED TSTM ACTIVITY AS IT INTERACTS WITH THE HIGHER TERRAIN IN
SRN COLO AND NRN NM. INCREASING NW FLOW ALOFT MAY DIRECT SOME OF
THIS ACTIVITY SEWD INTO OUR NW COUNTIES SUNDAY EVENING. THE FRONT
WILL LIKELY SLIP INTO OUR CWA SUNDAY NIGHT AND MONDAY...ALTHOUGH
THE EXACT PROGRESSION IS UNCERTAIN. THIS SHOULD BRING AT LEAST A
MODEST DROP IN TEMPS AND A BETTER CHANCE OF TSTM DEVELOPMENT
MONDAY AFTERNOON AND EVENING WITH THE FRONT /HOPEFULLY/ IN THE
AREA AND BETTER MID-LVL INSTABILITY AS THE UPPER RIDGE SHIFTS TO
THE WEST. IN GENERAL...OUR CWA SHOULD SEE A PERIOD OF NW FLOW
ALOFT...AND MOIST UPSLOPE FLOW AT THE SURFACE TUES THROUGH
THURS...WHICH WILL KEEP RAIN IN THE FORECAST DURING THAT PERIOD.
THE DETAILS REMAIN UNCLEAR HOWEVER. MEDIUM-RANGE GUIDANCE SHOWS A
STRONG PREFERENCE FOR THUNDERSTORM ACTIVITY ALONG AN AXIS RUNNING
FROM SRN COLO...SEWD ACROSS THE PANHANDLES...INTO WRN OKLA AND THE
RED RIVER VALLEY. THIS PUTS OUR NE ZONES IN THE BEST LOCATION FOR
RAIN...WITH CHANCES TAPERING DOWN TO THE SOUTH AND WEST. GUIDANCE
ALSO SUGGESTS A WELL-DEVELOPED MCS WED NIGHT...TIED TO A DISTINCT
SHORTWAVE DIVING THROUGH THE PLAINS. IF THIS OCCURS...IT MAY DRIVE
A REINFORCING SHOT OF COOL AIR THROUGH THE AREA THURSDAY. BY LATE
WEEK...GUIDANCE SHOWS A DEEP TROUGH OVER THE EASTERN U.S. WITH THE
UPPER RIDGE AXIS BACK ACROSS THE DESERT SW AND GREAT BASIN. THE BEST
FOCUS FOR RAIN IN THIS PATTEN MAY BE TO OUR SOUTH AND WEST...BUT
UPPER-FLOW MAY BE STRONG ENOUGH TO BRING SOME ACTIVITY EASTWARD
INTO OUR WRN COUNTIES. AS FOR TEMPS...AFTER MAXING OUT OVER THE
WEEKEND...WE SHOULD SEE THEM GRADUALLY FALLING BACK THROUGH MID-
WEEK. THU MAY BE THE COOLEST DAY OF THE PERIOD...WITH HIGHS ONLY
IN THE 80S. IN THE FORECAST PATTERN WE WOULD USUALLY EXPECT ONLY A
GRADUAL...MODEST WARMING TREND HEADING INTO NEXT WEEKEND.

.AVIATION...
CONTD VFR WITH LIGHT SELY WINDS VEERING S-SW AFTER 06Z. PRESENTLY
JUST A FEW SMALL SHRA/TSRA ARE FOUND ABOUT 40S LBB MOVG W...BUT
THESE WILL DECAY BY SUNSET AND NOT AFFECT THE TERMINAL.

&&

.PREV DISCUSSION... /ISSUED 314 PM CDT THU JUL 24 2014/

SHORT TERM...
ANALYSIS OF THE 12Z UPA DATA SHOWS THAT THE RIDGE CONTINUES TO
SLOWLY SETTLE OVER THE AREA ALTHOUGH HEIGHTS ARE STARTING TO FALL
JUST A BIT COMPARED TO THE SAME TIME YESTERDAY.  DECENT CU FIELD HAS
DEVELOPED ACROSS THE AREA THIS AFTERNOON AND IS A BIT MORE EXPANSIVE
COMPARED TO YESTERDAY.  WITH THE RIDGE ON TOP OF US RESULTING IN
SUBSIDENCE AND DEEPER MOISTURE TOO FAR WEST AND EAST OF US...IT
APPEARS THAT CHANCES FOR ANY STORM DEVELOPMENT ARE SLIM TO NONE.
RUC/HRRR/AND ARW-WEST ARE ALL STILL TRYING TO GENERATE SCATTERED
STORMS THIS AFTERNOON WHILE THE NAM/GFS/TTU WRF KEEP THINGS DRY.
WILL GO WITH NO POPS FOR TONIGHT ACROSS THE FORECAST AREA WITH MILD
TEMPERATURES FOR MORNING LOWS FRIDAY.  HIGHS HAVE BEEN PROBLEMATIC
THE LAST COUPLE OF DAYS...MOS GUIDANCE HAS BEEN CONSISTENTLY
OVERDOING TEMPS BY 3-5 DEGREES ACROSS THE REGION.  VERIFICATION
NUMBERS SHOW THAT BY FAR THE BEST PERFORMING FIELDS FOR TEMPERATURES
HAVE BEEN EITHER THE BIAS CORRECTED CONSENSUS RAW OR WEIGHTED MODEL
FIELDS AND HAVE OPTED TO GO WITH THE WEIGHTED MODELS FOR HIGHS
TOMORROW.  THIS KEEPS TEMPS IN THE MID TO UPPER 90S FOR THE CAPROCK
WITH 99 TO 102 FOR THE ROLLING PLAINS.

JORDAN

LONG TERM...
THE EXTENDED FORECAST MAY START OFF HOT AND DRY...BUT WILL END
DRAMATICALLY DIFFERENT AS COOLER AND WETTER CONDITIONS ARE
ANTICIPATED.

THE UA RIDGE WILL CONTINUE TO BE A DOMINATING SYNOPTIC FEATURE ON
SATURDAY...THOUGH IT WILL BE LESS AMPLIFIED COURTESY OF AN UA LOW
SYSTEM THAT WILL TRANSLATE EAST ACROSS SRN CANADA. DESPITE A
FLATTER UA RIDGE...THE SLIGHT UPTICK IN MID-UPPER LEVEL THICKNESS
VALUES AND 850 MB TEMPS RANGING BETWEEN 27-32 DEGREES C SUGGEST HOT
TEMPS WILL ENDURE /UPPER 90S TO LOWER TRIPLE DIGIT READINGS/.
RELATIVELY WEAK EMBEDDED IMPULSES WILL ROUND THE UA RIDGE AND AID TO
IGNITE STORMS ACROSS NE NEW MEXICO SATURDAY EVENING. A FEW MODEL
SOLUTIONS SHOW THE PRECIP ACTIVITY POSSIBLE NEARING THE FAR SW TX
PANHANDLE BY THE EVENING...THOUGH VERY WEAK STEERING FLOW WILL
LIKELY MAINTAIN THE ACTIVITY ACROSS THE PANHANDLES AND ERN NEW
MEXICO.

LATE WEEKEND INTO EARLY NEXT WEEK...THE AFOREMENTIONED UA LOW WILL
DIVE SE ACROSS THE GREAT LAKES REGION THUS CAUSING THE UA RIDGE TO
RETROGRADE TOWARDS THE DESERT SW. AS SUCH...NW FLOW ALOFT WILL
SHARPEN. THE NAM IS A BIT QUICKER IN SHOWING THIS EVOLUTION AND AS A
RESULT...IS QUICKER IN DEPICTING THE ARRIVAL OF A COLD FRONT AND
ASSOCIATED PRECIP SUNDAY EVENING. THE GFS AND ECMWF ON THE OTHER
HAND ARE A TAD SLOWER ON ALL COUNTS...THEREBY SHOWING THE COLD FRONT
AND PRECIP IMPINGING ON THE FA LATE SUNDAY NIGHT/EARLY MONDAY
MORNING. HENCE...A FEW DETAILS STILL NEEDS TO BE HASHED OUT.
NONETHELESS...A COOLER AND WETTER TREND IS STILL BEING EXHIBITED
NEXT WEEK...AS MOUNTAINOUS CONVECTION ACROSS NEW MEXICO COULD
PROPAGATE ACROSS THE REGION THANKS TO NW FLOW ALOFT AND THE PRESENCE
OF A COLD PASSAGE. FURTHERMORE...ANOTHER COLD FRONT IS BEING
DEPICTED ON WEDNESDAY AND WITH PWATS ENDURING ABOVE 1.00
INCH...ADDITIONAL RAIN CAN NOT BE RULED OUT. WILL THEREFORE MAINTAIN
THE INHERITED SLIGHT CHANCE/CHANCE POPS COMMENCING SUNDAY
NIGHT-WEDNESDAY. INCREASING CLOUDINESS AND RAIN CHANCES WILL HAVE AN
EFFECT ON TEMPS...WITH HIGHS IN THE UPPER 80S TO LOWER TO MIDDLE 90S
EXPECTED FOR NEXT WEEK.

PREV DISCUSSION... /ISSUED 356 AM CDT THU JUL 24 2014/

SHORT TERM...
THE PERSISTENT UPPER RIDGE CENTERED OVER NRN NM AND SRN COLO WILL
TEND TO ELONGATE E-W TODAY...WHICH SHOULD RESULT IN A SLIGHT
INCREASE IN HEIGHTS ACROSS OUR CWA. WATER VAPOR IMAGERY SHOWS A WEAK
DISTURBANCE AND DEEPER MOISTURE FIELD STRETCHING FROM SRN OKLA INTO
WEST-CENTRAL TX. THIS DISTURBANCE WILL MOVE TO THE SOUTHWEST AROUND
THE UPPER HIGH TODAY...SKIRTING OUR SRN ZONES. LARGE-SCALE
SUBSIDENCE ASSOCIATED WITH THE RIDGE SHOULD SUPPRESS MOST BUT
PERHAPS NOT ALL CONVECTION. ISOLATED SHOWER AND T-STORM ACTIVITY IS
POSSIBLE ACROSS OUR SRN COUNTIES THIS AFTERNOON...BUT THE COVERAGE
SEEMS TOO LOW TO ADD TO THE FORECAST AT THIS TIME. TEMPERATURES MAY
BE JUST SLIGHTLY WARMER TODAY GIVEN THE SUBTLE WARMING ALOFT...HIGHS
SHOULD BE IN THE MIDDLE TO UPPER 90S ON THE CAPROCK AND UPPER 90S TO
ABOUT 102 IN THE ROLLING PLAINS. ANY DIURNAL CONVECTION SHOULD DIE
OFF QUICKLY IN THE EVENING WITH A MOSTLY CLEAR AND MILD NIGHT
EXPECTED.

LONG TERM...
FOR THE REST OF THIS WEEK...PRECIPITATION LOOKS MORE
UNLIKELY...SPECIFICALLY FOR FRIDAY AND SATURDAY EVENINGS. A FEW
SHORT WAVES ARE STILL PROGGED TO MOVE EASTWARD AROUND THE TOP OF
THE RIDGE BUT LOOK TO BE TOO FAR NORTH TO AFFECT THE REGION. THE
PANHANDLES MAY SEE MOST OF THE ACTIVITY FROM THESE SHORT WAVES.
FURTHERMORE...WEAK FLOW ALOFT WILL NOT BE CONDUCIVE FOR CONVECTION
TO MAKE IT INTO THE SOUTH PLAINS. NORTHWEST FLOW IS STILL FORECAST
TO STRENGTHEN NEXT WEEK AS THE RIDGE MOVES WEST AND AMPLIFIES.

PRECIPITATION MAY BEGIN AS EARLY AS SUNDAY WITH A COLD FRONT
APPROACHING THE AREA ON SUNDAY AND BECOMING QUASI-STATIONARY FROM
MONDAY THROUGH MID WEEK. A DRYING TREND DURING THE REST OF THE
WEEK MAY BE ERASED BY A SIGNIFICANT INCREASE IN PRECIPITABLE WATER
VALUES BEHIND THE FRONTAL BOUNDARY FOR NEXT WEEK. EXACT DETAILS
REMAIN UNCLEAR THIS FAR OUT IN THE FORECAST BUT THE EXTENDED

DISTURBANCE AND DEEPER MOISTURE FIELD STRETCHING FROM SRN OKLA INTO
WEST-CENTRAL TX. THIS DISTURBANCE WILL MOVE TO THE SOUTHWEST AROUND
THE UPPER HIGH TODAY...SKIRTING OUR SRN ZONES. LARGE-SCALE
SUBSIDENCE ASSOCIATED WITH THE RIDGE SHOULD SUPPRESS MOST BUT
PERHAPS NOT ALL CONVECTION. ISOLATED SHOWER AND T-STORM ACTIVITY IS
POSSIBLE ACROSS OUR SRN COUNTIES THIS AFTERNOON...BUT THE COVERAGE
SEEMS TOO LOW TO ADD TO THE FORECAST AT THIS TIME. TEMPERATURES MAY
BE JUST SLIGHTLY WARMER TODAY GIVEN THE SUBTLE WARMING ALOFT...HIGHS
SHOULD BE IN THE MIDDLE TO UPPER 90S ON THE CAPROCK AND UPPER 90S TO
ABOUT 102 IN THE ROLLING PLAINS. ANY DIURNAL CONVECTION SHOULD DIE
OFF QUICKLY IN THE EVENING WITH A MOSTLY CLEAR AND MILD NIGHT
EXPECTED.

&&

.LONG TERM...
FOR THE REST OF THIS WEEK...PRECIPITATION LOOKS MORE
UNLIKELY...SPECIFICALLY FOR FRIDAY AND SATURDAY EVENINGS. A FEW
SHORT WAVES ARE STILL PROGGED TO MOVE EASTWARD AROUND THE TOP OF
THE RIDGE BUT LOOK TO BE TOO FAR NORTH TO AFFECT THE REGION. THE
PANHANDLES MAY SEE MOST OF THE ACTIVITY FROM THESE SHORT WAVES.
FURTHERMORE...WEAK FLOW ALOFT WILL NOT BE CONDUCIVE FOR CONVECTION
TO MAKE IT INTO THE SOUTH PLAINS. NORTHWEST FLOW IS STILL FORECAST
TO STRENGTHEN NEXT WEEK AS THE RIDGE MOVES WEST AND AMPLIFIES.

PRECIPITATION MAY BEGIN AS EARLY AS SUNDAY WITH A COLD FRONT
APPROACHING THE AREA ON SUNDAY AND BECOMING QUASI-STATIONARY FROM
MONDAY THROUGH MID WEEK. A DRYING TREND DURING THE REST OF THE
WEEK MAY BE ERASED BY A SIGNIFICANT INCREASE IN PRECIPITABLE WATER
VALUES BEHIND THE FRONTAL BOUNDARY FOR NEXT WEEK. EXACT DETAILS
REMAIN UNCLEAR THIS FAR OUT IN THE FORECAST BUT THE EXTENDED
PORTION OF THE FORECAST STILL DOES LOOK WETTER AND COOLER.

LONG TERM...
SOMEWHAT SIGNIFICANT CHANGES WERE MADE IN THE LONG TERM NEXT WEEK
WITH HIGHER CONFIDENCE IN A COOLER AND WETTER PATTERN. IN THE
MEANTIME...HEIGHTS THIS WEEK WILL DECREASE WITH A FLATTENING
RIDGE. THIS RIDGE WILL FLATTEN FROM A PROGRESSIVE SYSTEM MOVING

SATURDAY. TEMPERATURES AREA WIDE LOOK TO BREAK 100 DEGREES. AT THE
MOMENT...IT LOOKS AS THOUGH HEAT ADVISORY CRITERIA WILL NOT BE MET
ALTHOUGH WILL COME CLOSE BOTH OF THESE AFTERNOONS.

WE STILL START TO SEE WEAK NORTHWEST FLOW AS EARLY AS FRIDAY AS
THE FLATTENED RIDGE MOVES BACK WEST. A FEW WEAK IMPULSES WILL MOVE
OVER TOP OF THE RIDGE FRIDAY AND SATURDAY GENERATING CONVECTION
OFF THE FRONT RANGE AND HIGHER TERRAIN OF EASTERN NEW MEXICO. BUT
ATMOSPHERIC FLOW WILL STILL BE WEAK WHICH WILL LIMIT THE ABILITY
OF CONVECTION TO MOVE INTO WEST TEXAS. STRONGER NORTHWEST FLOW
WILL TAKE SHAPE EARLY NEXT WEEK AS WE MAKE A PATTERN CHANGE.

THE AFOREMENTIONED UPPER LOW MOVING ACROSS SOUTHERN CANADA WILL
DIP DOWN INTO THE GREAT LAKES REGION BEING ABSORBED WITHIN THE
LONGWAVE TROUGH OVER THE EASTERN US. THIS SYSTEM WILL SEND A COLD
FRONT TO THE AREA EITHER ON SUNDAY OR MONDAY AND STALL OUT FOR A
FEW DAYS. THIS FRONT MAY PROVIDE A FOCUS FOR CONVECTION FOR
SEVERAL CONSECUTIVE DAYS NEXT WEEK FROM SUNDAY THROUGH WEDNESDAY.
ALTHOUGH PRECIPITATION CHANCES MAY BE DEPENDENT ON WHEN ANY SHORT
WAVES MOVE THROUGH THE NORTHWEST FLOW. IT IS STILL TOO EARLY FOR
TIMING ON ANY SHORT WAVES BUT THE GFS AND ECMWF BOTH SHOW A
STRONGER SHORT WAVE ON TUESDAY EVENING.

MORE. ANOTHER MILD NIGHT IS IN STORE WITH LOWS MAINLY IN THE MID 60S
TO MID 70S WITH LITTLE CLOUD COVER EXPECTED.

&&

.LONG TERM...
SOMEWHAT SIGNIFICANT CHANGES WERE MADE IN THE LONG TERM NEXT WEEK
WITH HIGHER CONFIDENCE IN A COOLER AND WETTER PATTERN. IN THE
MEANTIME...HEIGHTS THIS WEEK WILL DECREASE WITH A FLATTENING
RIDGE. THIS RIDGE WILL FLATTEN FROM A PROGRESSIVE SYSTEM MOVING
ACROSS SOUTHERN CANADA. HOWEVER...THICKNESS VALUES WILL RISE
WHICH WILL LEAD TO WARMER TEMPERATURES TOPPING OUT ON FRIDAY AND
SATURDAY. TEMPERATURES AREA WIDE LOOK TO BREAK 100 DEGREES. AT THE
MOMENT...IT LOOKS AS THOUGH HEAT ADVISORY CRITERIA WILL NOT BE MET
ALTHOUGH WILL COME CLOSE BOTH OF THESE AFTERNOONS.

WE STILL START TO SEE WEAK NORTHWEST FLOW AS EARLY AS FRIDAY AS
THE FLATTENED RIDGE MOVES BACK WEST. A FEW WEAK IMPULSES WILL MOVE
OVER TOP OF THE RIDGE FRIDAY AND SATURDAY GENERATING CONVECTION
OFF THE FRONT RANGE AND HIGHER TERRAIN OF EASTERN NEW MEXICO. BUT
ATMOSPHERIC FLOW WILL STILL BE WEAK WHICH WILL LIMIT THE ABILITY
OF CONVECTION TO MOVE INTO WEST TEXAS. STRONGER NORTHWEST FLOW
WILL TAKE SHAPE EARLY NEXT WEEK AS WE MAKE A PATTERN CHANGE.

THE AFOREMENTIONED UPPER LOW MOVING ACROSS SOUTHERN CANADA WILL
DIP DOWN INTO THE GREAT LAKES REGION BEING ABSORBED WITHIN THE
LONGWAVE TROUGH OVER THE EASTERN US. THIS SYSTEM WILL SEND A COLD
FRONT TO THE AREA EITHER ON SUNDAY OR MONDAY AND STALL OUT FOR A
FEW DAYS. THIS FRONT MAY PROVIDE A FOCUS FOR CONVECTION FOR
SEVERAL CONSECUTIVE DAYS NEXT WEEK FROM SUNDAY THROUGH WEDNESDAY.
ALTHOUGH PRECIPITATION CHANCES MAY BE DEPENDENT ON WHEN ANY SHORT
WAVES MOVE THROUGH THE NORTHWEST FLOW. IT IS STILL TOO EARLY FOR
TIMING ON ANY SHORT WAVES BUT THE GFS AND ECMWF BOTH SHOW A
STRONGER SHORT WAVE ON TUESDAY EVENING.

.PREV DISCUSSION... /ISSUED 648 PM CDT TUE JUL 22 2014/

UPDATE...
MOST OF THE THUNDERSTORMS ACROSS THE SOUTH PLAINS HAVE DIMINISHED
ACROSS THE SOUTH PLAINS WITH THE EXCEPTION OF A FEW WEAK REMAINING
CELLS...LIKELY DUE TO A COMBINATION OF THE LOSS OF PEAK DIURNAL
HEATING AND THE STABILIZING EFFECT OF OUTFLOW FROM EARLIER
ACTIVITY. MUCH MORE VIGOROUS ACTIVITY CONTINUES FARTHER NORTH
ACROSS THE TEXAS PANHANDLE WHERE STRONGER FLOW ALOFT HAS ALLOWED
STORMS TO BECOME MORE ORGANIZED. THUS...UPDATED POPS TO REMOVE
MENTION ACROSS PORTIONS OF THE REGION...PARTICULARLY ACROSS THE
SOUTHERN ROLLING PLAINS AND MUCH OF THE CENTRAL AND SOUTHERN SOUTH
PLAINS AS WELL. THERE REMAINS A POSSIBILITY THAT AT A FEW STORMS
MAY SKIRT OUR NORTHWESTERN COUNTIES THROUGH THE EARLY OVERNIGHT
HOURS...AND THUS MAINTAINED POPS ACROSS THESE AREAS THROUGH 06Z.
BEYOND THIS TIME...MOST OF THE THUNDERSTORM ACTIVITY WILL LIKELY
HAVE DIMINISHED.

AVIATION...
VFR CONDITIONS ARE EXPECTED AT BOTH TERMINALS 00Z WEDNESDAY
THROUGH 00Z THURSDAY. ISOLATED THUNDERSTORMS ACROSS THE SOUTH
PLAINS WILL DIMINISH THIS EVENING AND ARE NOT EXPECTED TO IMPACT
EITHER TERMINAL.

SHORT TERM...
COMBINATION OF THINGS HAVE COME TOGETHER TO PRODUCE SCATTERED
THUNDERSTORMS ACROSS THE SOUTHERN HALF OF THE FORECAST AREA THIS
AFTERNOON.  OUTFLOW BOUNDARIES FROM STORMS OVERNIGHT LAST NIGHT WERE
DRAPED ACROSS TWO AREAS THIS AFTERNOON...ONE EAST OF LUBBOCK ALONG
THE EDGE OF THE CAPROCK AND THE OTHER WEST OF LUBBOCK ALONG A
LEVELLAND TO SEAGRAVES LINE.  SECOND THING WAS AMPLE MOISTURE AT
BOTH 850 AND 700 HPA AS SHOWN IN THE 12Z UPA ANALYSIS ALONG WITH
SOMEWHAT HIGHER LAPSE RATES AT KAMA COMPARED TO KMAF.  THIRD WAS
SEEN IN A 24 HOUR WATER VAPOR LOOP...THE REMNANTS OF A THE LARGE
AREA OF CONVECTION ACROSS KS/OK/TX PANHANDLE YESTERDAY EVENING ALONG
WITH THE OVERNIGHT CONVECTION CLOSER TO HOME WAS LOCATED ACROSS THE
AREA.  THIS FEATURE MAY PROVIDE SOME MID-LEVEL COOLING ALONG WITH
RESIDUAL LIFT THAT HELPED TO GET STORMS GOING THIS AFTERNOON.
MODELS HAVE BEEN OFF ON THE LOCATION OF CONVECTION WITH MOST OF THE
OPERATIONAL RUNS TOO FAR NORTH WITH DEVELOPMENT OF THE STRONGER
STORMS BUT WE ARE STARTING TO SEE SOME DEVELOPMENT ACROSS THE
NORTHERN PORTIONS AS WELL.

STEERING FLOW IS RELATIVELY WEAK WITH THE CENTER OF THE RIDGE AT 500
HPA LOCATED NORTHWEST OF THE AREA.  6 KM BULK SHEAR VALUES WERE
GENERALLY AT OR BELOW 10 KTS ACROSS THE REGION WITH THE STRONGEST
WINDS AROUND 250 HPA.  NORTH TO NORTHEAST 25 KT WIND IS HELPING TO
STEER THE STRONGER ACTIVITY TOWARDS THE SOUTHWEST AND EASTERLY
SURFACE FLOW IS ALSO HELPING TO PUSH THE STRONGER OUTFLOW WINDS TO
THE WEST AS WELL.  BIGGEST FORECAST UNCERTAINTY IS HOW LONG STORMS
WILL LAST INTO THIS EVENING AS POCKETS OF AIRMASS ARE STABILIZED BY
OUTFLOW BOUNDARIES AND NEW AREAS OF CONVECTION GENERATED ALONG
COLLIDING BOUNDARIES.  CONFIDENCE IS HIGH THAT WE SHOULD SEE MOST OF
THIS ACTIVITY DISSIPATE AFTER SUNSET AS WE LOSE SURFACE-BASED
INSTABILITY AND AS THE REMNANTS OF THE FORCING ALOFT MOVE SOUTHEAST
OF THE AREA.  WILL CARRY SOME ISOLATED POPS THROUGH 1 AM FOR ALL BUT
THE NORTHERN ROLLING PLAINS WHICH LOOKS TO BE TOO FAR REMOVED FROM
FORCING FOR ANY CHANCE AT SEEING PRECIPITATION.

TOMORROW SHOULD SEE THE RIDGE CONTINUE TO STRENGTHEN AND BUILD OVER
THE REGION SO TEMPERATURES WILL LIKELY BE A FEW DEGREES WARMER
ACROSS THE SOUTH PLAINS WITH NO CHANCE AT PRECIPITATION.  ONLY THING
THAT COULD IMPACT HIGH TEMPERATURES WILL BE ANY REMNANT CLOUD
COVER...SIMILAR TO WHAT WE SAW TODAY.  HOWEVER...MOST OF THE CLOUDS
BEING PRODUCED BY CURRENT STORMS ARE ALREADY OVER THE SOUTHERN HALF
OF THE FORECAST AREA AND SHOULD BE REMOVED FROM THE REGION BY
TOMORROW AFTERNOON.

LONG TERM...
THE UA RIDGE CONTINUES TO BE THE MAIN STORY FOR THE EXTENDED
FORECAST...AS IT WILL MORE OR LESS BE CENTERED ACROSS THE SOUTHERN
PLAINS THROUGH AT LEAST THE BEGINNING OF THE WEEKEND. MODEL
SOLUTIONS SHOW THE UA RIDGE FLATTENING A BIT DURING THE SAID
PERIOD...HOWEVER INCREASING MID-UPPER LEVEL THICKNESS VALUES SUGGEST
TEMPS WILL SOAR INTO THE UPPER 90S TO LOWER TRIPLE DIGIT
READINGS...WHICH IS SOME 10-12 DEGREES ABOVE CLIMO. HOT DAYS
FOLLOWED BY WARM NIGHTS /UPPER 60S TO LOWER TO MIDDLE 70S/ DOES
RAISE CONCERNS FOR POTENTIAL HEAT ADVISORY CONDITIONS...HOWEVER IT
APPEARS THE HEAT INDEX WILL BE SEVERAL DEGREES BELOW CRITERIA.
EMBEDDED WEAKNESS WILL BE ROUNDING THE UA RIDGE AND AID IN IGNITING
STORMS NE OF THE FA...AS WELL AS ACROSS THE HIGHER MOUNTAINOUS
TERRAIN OF NE NEW MEXICO. FLOW ALOFT WILL BE RELATIVELY WEAK AND
MOST OF THE PRECIP ACTIVITY MAY BE HARD-PRESSED TO IMPACT THE
REGION...THOUGH SOLUTIONS HINT AT PERHAPS NON-ZERO CHANCES FRIDAY
AND SATURDAY NIGHTS ACROSS THE SW TX PANHANDLE.

BY THE END OF THE WEEKEND INTO EARLY NEXT WEEK...AN UA LOW WHICH
SKIRTED EAST ACROSS SRN CANADA WILL DIVE SE TO ACROSS THE GREAT
LAKES REGION...WHICH WILL PROMOTE THE OPPRESSIVE UA RIDGE TO
RETROGRADE WEST TO NEAR THE FOUR-CORNERS REGION /THUS NO LONGER
CENTERED DIRECTLY OVERHEAD/. THIS WILL MAKE WAY FOR A BACKDOOR COLD
FRONT SUNDAY/MONDAY AND THE POTENTIAL FOR PRECIP ALONG THE
FRONT...AS WELL AS COOLER CONDITIONS /HIGHS IN LOWER TO MIDDLE 90S
BY EARLY NEXT WEEK/. FURTHERMORE WITH NW FLOW ALOFT BECOMING
ESTABLISHED...THIS WILL AID IN PROPAGATING STORMS FROM NEW MEXICO TO
ACROSS THE FA AS HINTED AT BY LONG TERM SOLUTIONS. A LINGERING COLD
FRONTAL BOUNDARY AND AN UPSLOPE SFC REGIME MAY CAUSE ADDITIONAL
CHANCES FOR PRECIP ON TUESDAY. WILL THEREFORE MAINTAIN INHERITED
SLIGHT CHANCE POPS ACROSS THE NRN ZONES SUNDAY NIGHT-TUESDAY.

THE UA RIDGE CONTINUES TO BE THE MAIN STORY FOR THE EXTENDED
FORECAST...AS IT WILL MORE OR LESS BE CENTERED ACROSS THE SOUTHERN
PLAINS THROUGH AT LEAST THE BEGINNING OF THE WEEKEND. MODEL
SOLUTIONS SHOW THE UA RIDGE FLATTENING A BIT DURING THE SAID
PERIOD...HOWEVER INCREASING MID-UPPER LEVEL THICKNESS VALUES SUGGEST
TEMPS WILL SOAR INTO THE UPPER 90S TO LOWER TRIPLE DIGIT
READINGS...WHICH IS SOME 10-12 DEGREES ABOVE CLIMO. HOT DAYS
FOLLOWED BY WARM NIGHTS /UPPER 60S TO LOWER TO MIDDLE 70S/ DOES
RAISE CONCERNS FOR POTENTIAL HEAT ADVISORY CONDITIONS...HOWEVER IT
APPEARS THE HEAT INDEX WILL BE SEVERAL DEGREES BELOW CRITERIA.
EMBEDDED WEAKNESS WILL BE ROUNDING THE UA RIDGE AND AID IN IGNITING
STORMS NE OF THE FA...AS WELL AS ACROSS THE HIGHER MOUNTAINOUS
TERRAIN OF NE NEW MEXICO. FLOW ALOFT WILL BE RELATIVELY WEAK AND
MOST OF THE PRECIP ACTIVITY MAY BE HARD-PRESSED TO IMPACT THE
REGION...THOUGH SOLUTIONS HINT AT PERHAPS NON-ZERO CHANCES FRIDAY
AND SATURDAY NIGHTS ACROSS THE SW TX PANHANDLE.

BY THE END OF THE WEEKEND INTO EARLY NEXT WEEK...AN UA LOW WHICH
SKIRTED EAST ACROSS SRN CANADA WILL DIVE SE TO ACROSS THE GREAT
LAKES REGION...WHICH WILL PROMOTE THE OPPRESSIVE UA RIDGE TO
RETROGRADE WEST TO NEAR THE FOUR-CORNERS REGION /THUS NO LONGER
CENTERED DIRECTLY OVERHEAD/. THIS WILL MAKE WAY FOR A BACKDOOR COLD
FRONT SUNDAY/MONDAY AND THE POTENTIAL FOR PRECIP ALONG THE
FRONT...AS WELL AS COOLER CONDITIONS /HIGHS IN LOWER TO MIDDLE 90S
BY EARLY NEXT WEEK/. FURTHERMORE WITH NW FLOW ALOFT BECOMING
ESTABLISHED...THIS WILL AID IN PROPAGATING STORMS FROM NEW MEXICO TO
ACROSS THE FA AS HINTED AT BY LONG TERM SOLUTIONS. A LINGERING COLD
FRONTAL BOUNDARY AND AN UPSLOPE SFC REGIME MAY CAUSE ADDITIONAL
CHANCES FOR PRECIP ON TUESDAY. WILL THEREFORE MAINTAIN INHERITED
SLIGHT CHANCE POPS ACROSS THE NRN ZONES SUNDAY NIGHT-TUESDAY.

SHORT TERM...
REMNANT SHOWERS AND CLOUD SHIELD CONTINUE TO BEND SOUTHWARD OVER THE
UPPER LEVEL RIDGE AXIS CURRENTLY NEAR THE TEXAS-NEW MEXICO BORDER.
THIS REGION HAS HAD MAXIMUM UPPER DIVERGENCE THE PAST 12 HOURS OR SO
WHILE A MESO-SCALE CONVECTIVE VORTICITY MAXIMUM LOOKS LIKE A REAL
POSSIBILITY TO REMAIN NEAR OUR WESTERN BORDER INTO THE MIDDAY
HEATING PERIOD. THE UPPER RIDGE WILL EXPAND NORTHWEST AND BUILD

LONG TERM...
THE UPPER LEVEL RIDGE WILL CONTINUE TO OPPRESS THE AREA THROUGH
THE LONG TERM FORECAST. THE RIDGE WILL FLATTEN AND ELONGATE AS A
SYSTEM MOVES THROUGH SOUTHERN CANADA AND THEN INTO THE GREAT
LAKES. SEVERAL WEAKNESSES WILL COME OVER THE TOP OF THE RIDGE
TOWARDS THE END OF THE WEEK AND THROUGH THE WEEKEND. HOWEVER...THE
AMOUNT OF MOISTURE IN THE ATMOSPHERE WILL BE LOWER THAN OBSERVED
IN THE PAST FEW DAYS. MODELS DO AGREE IN DEVELOPING CONVECTION OFF
THE HIGHER TERRAIN TO THE WEST IN RESPONSE TO THESE WEAKNESSES. IT
REMAINS HIGHLY UNCERTAIN ON WHETHER THIS ACTIVITY WOULD BE ABLE TO
REACH WEST TEXAS GIVEN THE PROXIMITY OF THE RIDGE AND WEAK
ATMOSPHERIC FLOW. ALTHOUGH THE RIDGE WILL FLATTEN...THICKNESSES
WILL RISE BY THE END OF THE WEEK LEADING TO TEMPERATURES AROUND
TEN DEGREES ABOVE SEASONAL AVERAGES. AT THE MOMENT...WE LOOK TO
REMAIN SEVERAL DEGREES SHORT OF HEAT ADVISORY CRITERIA.

AFTER THE AFOREMENTIONED UPPER LEVEL LOW DIVES INTO THE GREAT
LAKES...THE RIDGE WILL UNDERGO A RETROGRADE WESTWARD AND
AMPLIFICATION. MODELS SHOW THE SYSTEM IN THE GREAT LAKES SENDING
DOWN A COLD FRONT ON MONDAY. THIS MAY LEAD TO COOLER CONDITIONS

UPDATE...
MINOR UPDATE TO READJUST POPS AND TWEAK SEVERAL OTHER SHORT TERM
GRIDS. ISOLATED CONVECTION THAT DEVELOPED ACROSS THE WESTERN SOUTH
PLAINS THIS AFTERNOON HAS LONG SINCE DISSIPATED. HOWEVER...A
DECENT LINE OF SLOW-MOVING STORMS HAS CONGEALED FROM PARTS OF
SOUTHWEST KANSAS THROUGH THE NORTHWEST TEXAS PANHANDLE INTO
NORTHEAST NEW MEXICO. THE CONVECTION WITHIN THE LINE WAS GENERALLY
EDGING EASTWARD...BUT NEW DEVELOPMENT HAS OCCURRED ON THE SOUTHERN
FLANK AS AN OUTFLOW BOUNDARY CONTINUES TO ADVANCE SOUTHWARD TOWARD
CLOVIS AND BOOTLEG. THIS OUTFLOW WILL LIKELY MOVE INTO THE FAR
NORTHWEST ZONES SHORTLY...AND WITH A RELATIVELY MOIST/UNSTABLE
20-30 KNOT SOUTHEASTERLY LLJ IN PLACE...ADDITIONAL CONVECTIVE
DEVELOPMENT COULD OCCUR THROUGH THE LATE EVENING HOURS. THAT
SAID...CONVECTIVE INHIBITION DOES CONTINUE TO INCREASE...AND ASIDE
FROM THE LOW-LEVEL FORCING WITH THE OUTFLOW...LARGE SCALE SUPPORT
IS LACKING UNDER THE UPPER RIDGE. THUS...HOW FAR SOUTHEAST THE
CONVECTION CAN BE MAINTAINED AND DEVELOP IS IN QUESTION.
HENCE...WE HAVE REORIENTED THE POP/WX GRIDS TO REFLECT A 15-25
PERCENT CHANCE OF STORMS ACROSS THE FAR SOUTHWEST TEXAS PANHANDLE
AND NORTHWESTERN SOUTH PLAINS...WHILE REMOVING THE ISOLATED
THUNDER MENTION ACROSS THE SOUTHWEST SOUTH PLAINS. IF STORMS CAN
MAKE IT INTO THE AREA...THE SLOW STORM MOTION AND PWATS AROUND 1.3
INCHES COULD SUPPORT A FEW HEAVIER DOWNPOURS...THOUGH THE ACTIVITY
SHOULD GRADUALLY DECREASE IN COVERAGE AND INTENSITY THROUGH THE
LATE EVENING HOURS. IN ADDITION...WE DID TWEAK THE
DEWPOINT...TEMPERATURES AND SKY COVER GRIDS IN THE NEAR TERM TO
ACCOUNT FOR RECENT OBSERVATIONS AND TRENDS. NO OTHER CHANGES WERE
MADE ATTM.

PREV DISCUSSION... /ISSUED 341 PM CDT MON JUL 21 2014/

SHORT TERM...
CONVECTIVE INITIATION IN PROGRESS ACROSS LEA AND ROOSEVELT COUNTY IN
EASTERN NEW MEXICO ALONG THE TEXAS BORDER...WITH PORTIONS OF
BAILEY-COCHRAN-YOAKUM COUNTIES FOLLOWING SUIT AS INDICATED BY
SATELLITE AND RADAR...SOUTHEAST SURFACE WINDS AND DEEP MOISTURE
CONVERGING WITHIN A THERMAL LOW OVER NORTHEAST NEW MEXICO CURRENTLY
POSITIONED UNDER AN UPPER LEVEL RIDGE CENTERED ACROSS THE SOUTHERN
ROCKIES WILL SUPPORT ISOLATED THUNDERSTORMS THAT WILL TAPER OFF
DIURNALLY LATER THIS EVENING...WITH ANEMIC UPPER LEVEL STEERING
FLOW...STORMS WILL BE RELATIVELY STATIONARY AND COULD RESULT IN SOME
HEAVY RAINFALL FOR SOME SPOTS IN BAILEY-COCHRAN-YOAKUM COUNTIES
LATER THIS EVENING...THUNDERSTORM ACTIVITY WILL DIE DOWN TONIGHT
WITH WARM OVERNIGHT LOWS BOTTOMING OUT IN THE LOW-MID 70S FOR MOST.

TUESDAY WILL UNFOLD SIMILARLY TO TODAY...WARM START WILL LEAD
TO AN INCREMENTALLY HOTTER DAY WITH HIGHS APPROACHING 100 THROUGHOUT
THE SOUTHERN TEXAS PANHANDLE AND WEST TEXAS...WITH A WEAK SURFACE
FRONT EXTENDING DOWN INTO WEST TEXAS LATE TUESDAY AND ANOTHER
THERMAL LOW DEVELOPING IN EASTERN NEW MEXICO...THUNDERSTORMS LATE
TUESDAY AFTERNOON WITH POTENTIAL OF MORE COVERAGE...BUT SIMILAR TO
TODAY...SEVERE POTENTIAL WILL BE LOW.

LONG TERM...
UPPER HIGH WILL CONTINUE TO DOMINATE OUR WEATHER PATTERN BUT DESPITE
WARM TEMPERATURES ALOFT AND SOME WEAK SUBSIDENCE...VERY HUMID AIR
REMAINS BENEATH THE RIDGE AND WE EXPECT AT LEAST ISOLATED COVERAGE
OF STORMS NEAR THE NEW MEXICO BORDER THIS AFTERNOON/EVENING AND
AGAIN TUESDAY AFTERNOON AND EVENING. MODELS ARE SHOWING A VORTICITY
LOBE ROTATING NEAR THE CENTER OF THE HIGH AND SLIGHTLY ENHANCING
CONVECTIVE ENVIRONMENT/POTENTIAL. INTRODUCED ISOLATED POPS ACROSS THE SW
PANHANDLE TUESDAY. FOR THE REMAINDER OF THE WEEK...UPPER RIDGE LOOKS
AS IF IT WILL BEGIN TO RETROGRADE AND EVEN WEAKEN SLIGHTLY TOWARD
THE END OF THE WEEK...WITH NW FLOW RETURNING. STILL VERY WARM
TEMPERATURES TO CONTINUE WITH HIGH IN THE 90S TO NEAR 104 IN THE
SOUTHERN ROLLING PLAINS BY THE END OF THE WEEK. HIGHEST HEAT INDICES
IN THE ROLLING PLAINS WILL REMAIN A FEW DEGREES BELOW 105 SO NO HEAT
ADVISORY NEEDED ATTM. WILL NEED TO WATCH TRENDS CLOSELY HOWEVER.

LATE IN THE WEEKEND...SOME DISAGREEMENT IN MEDIUM RANGE MODELS.
ECMWF (00Z RUN) KEEPS UPPER RIDGE ACROSS NE NM WHILE GFS MOVES UPPER
HIGH BACK TOWARD THE 4 CORNERS AREA IN AN INCREASINGLY AMPLIFIED
FLOW. WITHOUT AN UPDATED ECMWF RUN TO VERIFY...BASED THIS FCST ON
12Z GFS SOLUTION WITH STRONGER NW FLOW DEVELOPING LATE SUNDAY INTO
MONDAY WITH FRONT MOVING SOUTH INTO PANHANDLE. RAIN CHANCES ALTHOUGH
NOT HIGH...WOULD INCREASE IN THAT SCENARIO...AND BUMPED UP POPS AND
CLOUD COVER SLIGHTLY IN THAT TIME FRAME. JAMES

EXPECTING ISOLATED THUNDERSTORMS NEAR THE NEW MEXICO/TEXAS BORDER
LATER THIS EVENING...WELL TO THE WEST OF KCDS AND KLBB...WE WILL
SEE SOME CU DEVELOP LATER THIS AFTERNOON BUT OTHERWISE VFR
CONDITIONS THROUGH THE FORECAST PERIOD.

PREV DISCUSSION... /ISSUED 233 AM CDT MON JUL 21 2014/

SHORT TERM...
WE WILL SEE CONTINUED HEIGHT RISES TODAY UNDERNEATH A BUILDING
RIDGE. A SURFACE TROUGH WHICH HAS BEEN POSITIONED WELL INTO EASTERN
NEW MEXICO WILL BE CLOSER TO WEST TEXAS TODAY. CONVECTION WILL
LIKELY TRY TO INITIATE WITHIN THIS TROUGH AXIS ALTHOUGH THE
EXPANDING RIDGE WILL HAVE SOMETHING TO SAY ABOUT THAT. LOW LEVEL
CONVERGENCE FIELDS ARE MAXIMIZED IN THE EXTREME WESTERN PANHANDLE
SOUTHEASTWARD INTO EAST-CENTRAL NEW MEXICO. A WEAK AXIS OF HIGHER
THETA-E VALUES WILL BE WITHIN THIS SURFACE TROUGH. THE THETA-E
VALUES WILL BE SOMEWHAT LESS POTENT THAN OBSERVED IN THE PREVIOUS
FEW DAYS. THIS WILL STILL GENERATE ROBUST SURFACE INSTABILITIES
BETWEEN 2000 AND 3000 J/KG BY LATE IN THE AFTERNOON. ALMOST NO FLOW
IN THE MIDDLE TO UPPER ATMOSPHERE WILL GIVE LITTLE MOVEMENT TO
CONVECTION THAT DOES DEVELOP. CONVECTION THAT DOES DEVELOP COULD
PRODUCE A ROGUE WIND GUST GIVEN NEARLY 40 DEGREE DEW POINT
DEPRESSIONS. MUCH DEEPER MONSOONAL MOISTURE WILL RESIDE WELL WEST OF
THE REGION IN ARIZONA INTO WESTERN NEW MEXICO.

LONG TERM...
LITTLE TO DISAGREE WITH AS UPPER RIDGE CONTINUES EXPANDING JUST TO
OUR NORTHWEST TUESDAY AND WEDNESDAY. BETTER AGREEMENT TODAY THAT A
WAVE DIPPING THROUGH THE GREAT LAKES WEDNESDAY WILL HAVE MINOR
IMPACT THIS FAR WEST BENEATH THE OPPRESSIVE RIDGE...WITH AT MOST A
MINOR LIGHT WIND SHIFT PERHAPS SETTLING SOUTHWARD EARLY THURSDAY
MAINLY AFFECTING THE EASTERN PANHANDLE AND ROLLING PLAINS. THE
UPPER RIDGE IS EXPECTED TO FLATTEN SLIGHTLY AND ELONGATE AS A
TIGHTLY WOUND SYSTEM ROTATES FROM THE PACIFIC NORTHWEST WEDNESDAY
NIGHT INTO SOUTH-CENTRAL CANADA BY THE EARLY WEEKEND. THIS MAY
SHOVE A MORE VALID WIND SHIFT BOUNDARY SOUTHWARD TOWARDS THE
REGION BY MONDAY NEXT WEEK AS RIDGE RETROGRADES AND AMPLIFIES INTO
CLASSIC FOUR-CORNERS PATTERN. SO...MIGHT EXPECT THIS WOULD PRODUCE
VALID COOLING AND PERHAPS SOME IMPROVEMENT IN SHOWER PROSPECTS
DAYS 8 AND BEYOND. UNTIL THEN...BULK OF EVIDENCE POINTS TOWARDS
TEMPERATURES IN THE 5-10 DEGREES ABOVE NORMAL RANGE. SMALL CHANCE
THE ROLLING PLAINS COULD FLIRT WITH HEAT ADVISORY CONDITIONS...
MAINLY LATE IN THE WEEK. AIRMASS WILL SLOWLY DRY EARLY TO MID WEEK
AT LEAST...THOUGH SOLUTIONS AGREE MOISTURE LEVELS WILL IMPROVE
EASTERN ZONES BY THE END OF THE WEEK AND WEEKEND WHICH COULD THEN
TRANSLATE INTO ELEVATED HEAT INDICES. RMCQUEEN

UPDATE...
CONVECTION HAS BEEN LARGELY CONFINED TO THE HIGHER TERRAIN OF NEW
MEXICO AND SOUTHWEST TEXAS THIS EVENING...WITH LITTLE PROPAGATION
TO THE EAST. A COUPLE OF ISOLATED SHOWERS/STORMS HAVE BRIEFLY
ATTEMPTED TO DEVELOP EAST OF THE HIGHER TERRAIN BUT THEY HAVE HAD
LITTLE SUCCESS IN SUSTAINING THEMSELVES. COOLING TEMPERATURES AND
INCREASING CONVECTIVE INHIBITION...COUPLED WITH A LACK OF LARGER
SCALE FORCING...FAVOR LITTLE IN THE WAY OF ADDITIONAL CONVECTIVE
DEVELOPMENT. GIVEN THIS...WE HAVE REMOVED THE ISOLATED POPS ACROSS
THE WESTERN ZONES FOR THE REMAINED OF TONIGHT. THE DEWPOINT AND
WIND GRIDS WERE ALSO ADJUSTED SLIGHTLY TO ACCOUNT FOR RECENT
OBSERVATIONS AND TRENDS. NO OTHER CHANGES WERE MADE AT THIS POINT.

SHORT TERM...
MODEL AND OBSERVATIONAL TRENDS SEEM TO AGREE WITH BUILDING UPPER
LEVEL RIDGE. THIS HIGH PRESSURE SYSTEM STRENGTHENS TO 595 DM TONIGHT
WITH AXIS FROM SRN NM INTO THE WESTERN SOUTH PLAINS AND PANHANDLE.
WARM AIR ALOFT AND SUBSIDENCE ASSOCIATED WITH THIS FEATURE WILL
SQUASH ALL BUT ISOLATED CONVECTION THIS EVENING AND TONIGHT. THINK
EVEN THAT WILL BE SHORT LIVED BUT MAY DEVELOP ALONG DECENT
INSTABILITY AXIS FROM SERN NM INTO THE WRN PANHANDLE...WHERE SPC
MESOANALYSIS IS INDICATING 3000+ J/KG CAPE AT 3 PM. VERY WEAK WIND
SHEAR WILL INHIBIT ORGANIZATION AND MOVEMENT OF ANY UPDRAFTS THAT
CAN BREAK THROUGH SUBSIDENCE INVERSION SEEN ON BOTH KAMA AND KMAF
SOUNDINGS AROUND 10K FEET. SLY LOW LEVEL JET MAY AGAIN FEED A FEW

LONG TERM...
QUIET WEATHER CONTINUES TO BE THE STORY FOR THE LONG TERM. HIGH
PRESSURE WILL REMAIN OVERHEAD THROUGH THE END OF THE WEEK. A /COLD/

WILL PUSH THE HIGH PRESSURE THAT HAS RESIDED OVER US TO THE WEST
PLACING US IN NORTHWESTERLY FLOW. BOTH GLOBAL MODELS BRING DOWN A

1229 PM CDT SUN JUL 20 2014

.AVIATION...
UPPER RIDGE EXERTING MORE INFLUENCE. CUMULUS CLOUDS HAVE BEEN
SLOWER TO FORM...AND WILL BE LESS NUMEROUS TODAY. WE STILL EXPECT
ISOLATED SHOWERS/STORMS LATE AFTN/EVE ALONG THE NM BORDER IN AXIS
OF HIGHER INSTABILITY...BUT THEY WILL BE FEWER AND LIKELY
DISSIPATE QUICKER LATER TODAY...AND AS MENTIONED IN PREVIOUS
AVIATION DISCUSSION...THEY ARE EXPECTED TO REMAIN WELL WEST OF THE
LUBBOCK AND CHILDRESS TERMINALS. THERE IS AN OUTSIDE CHANCE OF A
FEW LOW CLOUDS AT KCDS MONDAY MORNING BUT NOT CONFIDENT ENOUGH TO
MENTION IN TAF AT THIS TIME.

&&

.PREV DISCUSSION... /ISSUED 626 AM CDT SUN JUL 20 2014/

AVIATION...
VFR IS EXPECTED THROUGH THE TAF PERIOD. ISOLATED THUNDERSTORMS ARE
ANTICIPATED TO DEVELOP WELL WEST OF THE TAF SITES BUT NOT AFFECT
THE TERMINALS THIS EVENING.

PREV DISCUSSION... /ISSUED 417 AM CDT SUN JUL 20 2014/

SHORT TERM...
AN UPPER RIDGE WILL BEGIN ITS BURGEONING EXTENSION TODAY AND WILL
LEAD TO SIGNIFICANT INCREASES IN HEIGHTS AND THICKNESS VALUES.
DESPITE THIS EXPANDING RIDGE...CONVECTION IS STILL EXPECTED TO
INITIATE OFF THE HIGHER TERRAIN OF NEW MEXICO THIS AFTERNOON AND
EVENING. HOWEVER...THE RIDGE WILL LEAD TO LESS COVERAGE THAN
OBSERVED IN THE PAST FEW DAYS. CONVECTION WILL HAVE A TOUGH TIME
MOVING INTO WEST TEXAS WITH WEAKER FLOW ALOFT.
ALTHOUGH...INSTABILITY WILL BE JUST AS ROBUST AS IN PREVIOUS DAYS
WITH HEALTHY INSTABILITIES BETWEEN 2000-3000 J/KG. SEVERE CHANCES
WITH THIS ACTIVITY REMAIN LOW GIVEN THE WEAK FLOW AND WARM
TEMPERATURES ALOFT.

LONG TERM...
THE UPPER LEVEL HIGH PRESSURE RIDGE WILL BECOME A CONSTANT FOR THE
WEEK AHEAD WITH CENTER JUST NORTHWEST OF OUR AREA. THIS WILL FAVOR
ABOVE NORMAL THOUGH NOT EXCEEDINGLY HOT TEMPERATURES...AND
SUPPRESSED THUNDER CHANCES. THERE REMAINS SLIGHT DISAGREEMENT ON
HANDLING OF A WAVE INTO THE MID-WEST EARLY IN THE WEEK AND
SUBSEQUENT PLAY OF A WEAK FRONT SOUTHWARD INTO THE SOUTHERN
PLAINS WITH ECMWF MORE-SO THIS OUTCOME THAN GFS. ONCE AGAIN WE
WILL PLAY THIS AS A 50-50 SPLIT THOUGH LEAVE OUT THUNDER MENTION
AS HEIGHTS LOOK TOO OPPRESSIVE. AN ENERGETIC LOW PRESSURE SYSTEM
CROSSING THE PACIFIC NORTHWEST LATE IN THE WEEK MAY SEND A MORE
ACTIVE FRONT SOUTHWARD INTO THE AREA AS IT EMERGES AND DEEPENS IN
THE EASTERN U.S. LATE NEXT WEEKEND. EFFECTS FROM THIS SYSTEM
ARE MAINLY DAY EIGHT AND BEYOND. RMCQUEEN

WITH THIS ACTIVITY REMAIN LOW GIVEN THE WEAK FLOW AND WARM
TEMPERATURES ALOFT.

&&

.LONG TERM...
THE UPPER LEVEL HIGH PRESSURE RIDGE WILL BECOME A CONSTANT FOR THE
WEEK AHEAD WITH CENTER JUST NORTHWEST OF OUR AREA. THIS WILL FAVOR
ABOVE NORMAL THOUGH NOT EXCEEDINGLY HOT TEMPERATURES...AND
SUPPRESSED THUNDER CHANCES. THERE REMAINS SLIGHT DISAGREEMENT ON
HANDLING OF A WAVE INTO THE MID-WEST EARLY IN THE WEEK AND
SUBSEQUENT PLAY OF A WEAK FRONT SOUTHWARD INTO THE SOUTHERN
PLAINS WITH ECMWF MORE-SO THIS OUTCOME THAN GFS. ONCE AGAIN WE
WILL PLAY THIS AS A 50-50 SPLIT THOUGH LEAVE OUT THUNDER MENTION
AS HEIGHTS LOOK TOO OPPRESSIVE. AN ENERGETIC LOW PRESSURE SYSTEM
CROSSING THE PACIFIC NORTHWEST LATE IN THE WEEK MAY SEND A MORE
ACTIVE FRONT SOUTHWARD INTO THE AREA AS IT EMERGES AND DEEPENS IN
THE EASTERN U.S. LATE NEXT WEEKEND. EFFECTS FROM THIS SYSTEM
ARE MAINLY DAY EIGHT AND BEYOND. RMCQUEEN

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
1145 PM CDT SAT JUL 19 2014

.AVIATION...
THERE IS A CHANCE THAT -SHRA OR -TSRA MAY AFFECT KLBB THROUGH 07
UTC. OTHERWISE...THE OVERNIGHT POTENTIAL FOR ANY THUNDER OR PRECIP AT
EITHER TERMINAL OVERNIGHT IS VERY LOW. THE POTENTIAL FOR LOWERED
CEILINGS SUNDAY MORNING DUE TO STRATUS ALSO APPEARS VERY LOW. VFR
CONDITIONS ARE EXPECTED THROUGH THE DAY SUNDAY.

&&

.PREV DISCUSSION... /ISSUED 1039 PM CDT SAT JUL 19 2014/

UPDATE...
THE STRONG/SEVERE CONVECTION IN EASTERN NM EARLIER THIS EVENING
HAS FINALLY MADE ITS WAY ACROSS THE TX/NM LINE...BUT IT HAS
WEAKENED CONSIDERABLY AS IT HAS DONE SO. GIVEN THAT THIS ACTIVITY
IS TENDING TO GUST OUT AND WITH THE COOLING BOUNDARY LAYER AND
INCREASING INHIBITION...WE EXPECT THIS GENERAL TREND TO CONTINUE.
THAT SAID...SOME LINGERING CONVECTION COULD PERSIST FOR SOME TIME
INTO THE OVERNIGHT HOURS GIVEN THE MODEST AND MOIST SOUTHERLY LOW
LEVEL JET IN PLACE. IN ADDITION...WE WILL HAVE TO SEE IF THE
ISOLATED TO WIDELY SCATTERED SHOWERS/STORMS IN NORTHEAST NM AND
THE WESTERN OKLAHOMA PANHANDLE CAN COMPLETE THEIR SOUTHEAST JOURNEY
INTO THE CWA...THOUGH ODDS OF THIS ARE PRETTY LOW. GIVEN THIS WE
HAVE DECREASED POPS FOR ALL BUT THE FAR WESTERN/SOUTHWESTERN
ZONES THROUGH THE REMAINDER OF THE NIGHT. NO OTHER ADJUSTMENTS
WERE MADE ATTM.

PREV DISCUSSION... /ISSUED 832 PM CDT SAT JUL 19 2014/

UPDATE...
THE ONGOING FORECAST REMAINS LARGELY IN PLACE...ASIDE FROM A FEW
MINOR ADJUSTMENTS TO THE WIND...DEWPOINT AND SKY GRIDS TO ACCOUNT
FOR THE MOST RECENT OBSERVATIONS AND TRENDS. CONVECTION THAT
ORIGINATED ACROSS THE HIGHER TERRAIN OF NM THIS AFTERNOON HAS MADE
DECENT PROGRESS EASTWARD...THOUGH IT HAS ALSO SHOWN A RECENT
WEAKENING TREND. HOWEVER...ADDITIONAL SCATTERED CONVECTION HAS
DEVELOPED MORE RECENTLY IN AN AREA OF CONVERGENCE ACROSS EASTERN
NM...WITH ADDITIONAL SCATTERED THUNDERSTORMS NOTED FROM NORTHEAST
NM INTO EXTREME SOUTHEAST CO AND THE WESTERN OKLAHOMA PANHANDLE. THE
GENERAL STEERING FLOW IS TO THE EAST AND SOUTHEAST...THOUGH AT A
FAIRLY SLOW PACE AS IS EVIDENT BY THE MINIMAL EASTWARD PROGRESSION
OF THE ROOSEVELT AND LEA COUNTY ACTIVITY. STILL...WITH GOOD
MOISTURE AND INSTABILITY ACROSS THE WESTERN ZONES...AND THE SOUTH
TO SOUTHEASTERLY LLJ EXPECTED TO INCREASE MODESTLY FROM 20 KNOTS
NOW TO AROUND 30 KNOTS BY 06Z THERE STILL REMAINS A GOOD CHANCE
SOME OF THE WESTERN AND NORTHWESTERN ZONES COULD EXPERIENCE A
STORM LATER TONIGHT...ESPECIALLY IF THE SCATTERED CONVECTION CAN
CONGEAL AND DEVELOP A DECENT COLD POOL. THE LATEST HIGH-RESOLUTION
GUIDANCE SUPPORTS TWO POSSIBILITIES...FIRST A SMALL CLUSTER MOVING
OUT OF EASTERN NM OVER THE NEXT COUPLE OF HOURS...WITH A SECOND
CLUSTER POTENTIALLY MOVING IN FROM THE NORTHWEST LATER TONIGHT.
NOT TOO CONFIDENT ON THE DETAILS OF HOW THINGS WILL ACTUALLY PLAY
OUT...BUT THE CURRENT EVIDENCE SUPPORTS THE SOLID CHANCE POPS
ACROSS THE WESTERN AND NORTHWESTERN ZONES. THUS...NO CHANGES HAVE
BEEN MADE TO THE POP AND WEATHER GRIDS ATTM. THE FAIRLY ROBUST
INSTABILITY COULD SUPPORT AN ISOLATED STRONG OR SEVERE STORM
THROUGH LATE EVENING WHILE THE RELATIVELY SLOW STORM MOTIONS AND
HIGH PWATS COULD LEAD TO LOCALLY HEAVY DOWNPOURS AS WELL.

PREV DISCUSSION... /ISSUED 640 PM CDT SAT JUL 19 2014/

AVIATION...
THERE IS A POSSIBILITY THAT SOME TSRA ACTIVITY WELL TO THE NORTH
AND WEST OF THE AREA THIS EVENING COULD AFFECT THE TERMINALS LATE
TONIGHT AND EARLY SUNDAY MORNING. WE INCLUDED THIS POTENTIAL IN
THE KLBB TAF BUT KEPT IT OUT OF KCDS DUE TO LOWER CONFIDENCE. THE
THREAT OF LOW STRATUS APPEARS MUCH LOWER THAN PREVIOUS NIGHT...BUT
IT IS NOT OUT OF THE QUESTION THAT THE CONVECTION COULD PRODUCE A
PERIOD OF LOWERED CEILINGS. VFR CONDITIONS EXPECTED FOR SUNDAY
AFTER 12 UTC OR SO.

PREV DISCUSSION... /ISSUED 253 PM CDT SAT JUL 19 2014/

SHORT TERM...
MOST OF THE REGION WILL REMAIN HIGH AND DRY FOR THE NEXT 24 HOURS.
THE EXCEPTION WILL BE THE WESTERN SOUTH PLAINS AND SOUTHWESTERN
PANHANDLE WHICH WILL LIKELY SEE A FEW THUNDERSTORMS LATE THIS
EVENING INTO THE EARLY MORNING HOURS. A MOIST UNSTABLE AIRMASS
CONTINUES ACROSS THE REGION WITH THE HIGHER THETA-E AIR GENERALLY
WEST OF I-27. WE EXPECT A FEW STORMS TO DEVELOPS ACROSS EASTERN NEW
MEXICO AND DEVELOP/PROPAGATE SOUTH SOUTHEAST BY LATE EVENING AIDED
BY STRENGTHENING LOW LEVEL JET. COVERAGE WILL BE MORE LIMITED TOWARD
THE CENTRAL SOUTH PLAINS. KEPT CHANCE POPS THROUGH TONIGHT FROM
ROUGHLY PLAINS TO LUBBOCK TO MEMPHIS. FAVORED TIME FRAME WILL BE
FROM 03-09Z. LOWS TONIGHT RATHER MILD FROM 65-71.

DOESN`T APPEAR THAT LOW CLOUDS WILL BE AS MUCH OF A THREAT SUNDAY
MORNING...ALTHOUGH THEY CANNOT BE RULED OUT...ESPECIALLY ACROSS THE
ROLLING PLAINS. UPPER HIGH BEGINS TO EXERT MORE OF AN INFLUENCE
SUNDAY AFTERNOON...WITH HIGHS BOUNCING BACK ABOVE NORMAL...FROM 93 IN
THE SOUTHERN PANHANDLE TO NEAR 100 IN THE SOUTHERN ROLLING PLAINS.
STILL SLIGHT CHANCE ALONG THE NEW MEXICO BORDER BUT LOWER POPS
AREAWIDE. JAMES

LONG TERM...
THUNDERSTORM ACTIVITY WILL BEGIN TO DECREASE AFTER SUNDOWN TOMORROW
NIGHT WITH POSSIBLY A FEW SHOWERS LINGERING BEFORE MIDNIGHT ACROSS
OUR NORTHWESTERN ZONES. THE UPPER LEVEL HIGH TO OUR WEST WILL THEN
MOVE ALMOST DIRECTLY OVERHEAD BY MONDAY WHICH WILL LEAVE US IN A
FAIRLY BENIGN AND HOT PATTERN THROUGH THE END OF THE WEEK. THE ONLY
POSSIBLE EXCEPTION WILL COME AROUND THE MIDDLE OF THE WEEK AS MODELS
CONTINUE TO SHOW A WEAK FRONT PUSH SOUTHWARD. THE GFS GETS THE FRONT
AS FAR AS THE TEXAS PANHANDLE BEFORE DISSIPATING WHAT IS LEFT OF IT.
THIS WOULD GIVE THE PANHANDLE...AND POSSIBLY OUR NORTHWESTERN
ZONES...A CHANCE OF PRECIP TUESDAY MORNING. THE ECMWF ON THE OTHER
HAND BRINGS THE FRONT TO THE TX/NM STATE LINE BY TUESDAY MORNING
BEFORE THE UPPER LEVEL HIGH SHIFTS SLIGHTLY WESTWARD WHICH SLOWLY
PUSHES THE FRONT INTO THE FA ON WEDNESDAY AND EXITING THE FA THURSDAY
AFTERNOON. THIS WOULD KEEP TEMPS ON THE /MILDER/ SIDE AS SURFACE
EASTERLY FLOW WOULD HELP BRING IN SOME COOLER AIR. THIS PROJECTION
WOULD ALSO GIVE US A CHANCE AT RAIN AREA WIDE OVER THE COURSE OF 2
DAYS. DUE TO MODEL SPREAD AND BOTH GLOBAL MODELS BEING CONSISTENT I
HAVE CONTINUED OUR TREND OF RIDING THE MIDDLE OF THE ROAD. I HAVE
KEPT MENTIONABLE POPS OUT OF THE FORECAST FOR THE TIME BEING BUT AM
STARTING TO SLOWLY LEAN TOWARDS THE ECMWF AS IT HAS BEEN MORE
CONSISTENT THAN THE GFS WHO HAS CHANGED THE PROJECTION OF THE FRONT
SLIGHTLY WITH EACH RUN.

BY THE WEEKEND THE HIGH WILL BEGIN TO BE DETERIORATED SOMEWHAT AS A
LOW SKIRTS TO THE NORTH ACROSS THE CA/TX LINE PUTTING US IN VERY
WEAK ZONAL FLOW BEFORE THE HIGH BUILDS WESTWARD PUTTING US IN
NORTHWESTERLY FLOW BY EARLY NEXT WEEK. BOTH MODELS PUSH ANOTHER
FRONT SOUTHWARD BY LATE MONDAY AND BOTH BRING THE FRONT INTO AT
LEAST OUR NORTHERN ZONES. THE ECMWF ACTUALLY BRINGS THE FRONT ALL
THE WAY THROUGH. THIS WOULD AGAIN GIVE US ANOTHER SHOT AT GENERAL
THUNDERSTORMS. ALDRICH

PANHANDLE WHICH WILL LIKELY SEE A FEW THUNDERSTORMS LATE THIS
EVENING INTO THE EARLY MORNING HOURS. A MOIST UNSTABLE AIRMASS
CONTINUES ACROSS THE REGION WITH THE HIGHER THETA-E AIR GENERALLY
WEST OF I-27. WE EXPECT A FEW STORMS TO DEVELOPS ACROSS EASTERN NEW
MEXICO AND DEVELOP/PROPAGATE SOUTH SOUTHEAST BY LATE EVENING AIDED
BY STRENGTHENING LOW LEVEL JET. COVERAGE WILL BE MORE LIMITED TOWARD
THE CENTRAL SOUTH PLAINS. KEPT CHANCE POPS THROUGH TONIGHT FROM
ROUGHLY PLAINS TO LUBBOCK TO MEMPHIS. FAVORED TIME FRAME WILL BE
FROM 03-09Z. LOWS TONIGHT RATHER MILD FROM 65-71.

DOESN`T APPEAR THAT LOW CLOUDS WILL BE AS MUCH OF A THREAT SUNDAY
MORNING...ALTHOUGH THEY CANNOT BE RULED OUT...ESPECIALLY ACROSS THE
ROLLING PLAINS. UPPER HIGH BEGINS TO EXERT MORE OF AN INFLUENCE
SUNDAY AFTERNOON...WITH HIGHS BOUNCING BACK ABOVE NORMAL...FROM 93 IN
THE SOUTHERN PANHANDLE TO NEAR 100 IN THE SOUTHERN ROLLING PLAINS.
STILL SLIGHT CHANCE ALONG THE NEW MEXICO BORDER BUT LOWER POPS
AREAWIDE. JAMES

LONG TERM...
THUNDERSTORM ACTIVITY WILL BEGIN TO DECREASE AFTER SUNDOWN TOMORROW
NIGHT WITH POSSIBLY A FEW SHOWERS LINGERING BEFORE MIDNIGHT ACROSS
OUR NORTHWESTERN ZONES. THE UPPER LEVEL HIGH TO OUR WEST WILL THEN
MOVE ALMOST DIRECTLY OVERHEAD BY MONDAY WHICH WILL LEAVE US IN A
FAIRLY BENIGN AND HOT PATTERN THROUGH THE END OF THE WEEK. THE ONLY
POSSIBLE EXCEPTION WILL COME AROUND THE MIDDLE OF THE WEEK AS MODELS
CONTINUE TO SHOW A WEAK FRONT PUSH SOUTHWARD. THE GFS GETS THE FRONT
AS FAR AS THE TEXAS PANHANDLE BEFORE DISSIPATING WHAT IS LEFT OF IT.
THIS WOULD GIVE THE PANHANDLE...AND POSSIBLY OUR NORTHWESTERN
ZONES...A CHANCE OF PRECIP TUESDAY MORNING. THE ECMWF ON THE OTHER
HAND BRINGS THE FRONT TO THE TX/NM STATE LINE BY TUESDAY MORNING
BEFORE THE UPPER LEVEL HIGH SHIFTS SLIGHTLY WESTWARD WHICH SLOWLY
PUSHES THE FRONT INTO THE FA ON WEDNESDAY AND EXITING THE FA THURSDAY
AFTERNOON. THIS WOULD KEEP TEMPS ON THE /MILDER/ SIDE AS SURFACE
EASTERLY FLOW WOULD HELP BRING IN SOME COOLER AIR. THIS PROJECTION
WOULD ALSO GIVE US A CHANCE AT RAIN AREA WIDE OVER THE COURSE OF 2
DAYS. DUE TO MODEL SPREAD AND BOTH GLOBAL MODELS BEING CONSISTENT I
HAVE CONTINUED OUR TREND OF RIDING THE MIDDLE OF THE ROAD. I HAVE
KEPT MENTIONABLE POPS OUT OF THE FORECAST FOR THE TIME BEING BUT AM
STARTING TO SLOWLY LEAN TOWARDS THE ECMWF AS IT HAS BEEN MORE
CONSISTENT THAN THE GFS WHO HAS CHANGED THE PROJECTION OF THE FRONT
SLIGHTLY WITH EACH RUN.

BY THE WEEKEND THE HIGH WILL BEGIN TO BE DETERIORATED SOMEWHAT AS A
LOW SKIRTS TO THE NORTH ACROSS THE CA/TX LINE PUTTING US IN VERY
WEAK ZONAL FLOW BEFORE THE HIGH BUILDS WESTWARD PUTTING US IN
NORTHWESTERLY FLOW BY EARLY NEXT WEEK. BOTH MODELS PUSH ANOTHER
FRONT SOUTHWARD BY LATE MONDAY AND BOTH BRING THE FRONT INTO AT
LEAST OUR NORTHERN ZONES. THE ECMWF ACTUALLY BRINGS THE FRONT ALL
THE WAY THROUGH. THIS WOULD AGAIN GIVE US ANOTHER SHOT AT GENERAL
THUNDERSTORMS. ALDRICH

STRATUS BEGINNING TO ERODE ACROSS WEST TEXAS. SHOULD SCT AT BOTH
TERMINALS SHORTLY. THUNDERSTORMS ARE EXPECTED TO DEVELOP ACROSS
ERN NM AND DEVELOP S/SE INTO PARTS OF WEST TEXAS MAINLY WEST OF
THE KLBB TERMINAL...BUT KEPT PROB30 AT KLBB FOR A FEW HOURS AFTER
03Z AS LOW LEVEL JET PROVIDES GOOD INFLOW DURING THE LATE EVENING

AVIATION...
LOW CIGS HAVE RETURNED TO THE REGION THIS MORNING AND WILL PERSIST
UNTIL LATE MORNING SIMILAR TO YESTERDAY. HOWEVER...LOWER
CONFIDENCE EXISTS IN LOW CIGS AFFECTING THE KLBB TERMINAL. AT THE
MOMENT...LOW CLOUDS WERE JUST EAST OF THE TERMINAL BUT WERE
DEVELOPING WEST OF THE TERMINAL. CONTINUED DEVELOPMENT IS EXPECTED
AND THUS HAVE INCLUDED A TEMPO IN THE TAF FOR MVFR CIGS. A COMPLEX
OF THUNDERSTORMS WILL BE POSSIBLE LATE TONIGHT INTO EARLY SUNDAY
MORNING WITH HIGHER CONFIDENCE AFFECTING KLBB THAN KCDS.

PREV DISCUSSION... /ISSUED 406 AM CDT SAT JUL 19 2014/

SHORT TERM...
OUR TYPICAL SUMMERTIME WEATHER PATTERN WILL CONTINUE FOR THE FIRST
HALF OF THE WEEKEND. CHANCES OF CONVECTION WILL BE A LITTLE HIGHER
TODAY THAN YESTERDAY. A WEAK SHORT WAVE WAS MOVING OVER TOP THE
RIDGE MOVING TOWARDS THE FOUR CORNERS EARLY THIS MORNING. THIS
FEATURE WILL PROVIDE A LITTLE EXTRA BOOST IN THE ATMOSPHERE BEFORE
THE RIDGE EVENTUALLY TAKES OVER LATER IN THE WEEKEND.
FURTHERMORE...WE WILL SEE HEIGHT FALLS AFTER 00Z THIS EVENING AFTER
SIGNIFICANT HEIGHT RISES BEFORE THIS TIME PERIOD. THE LOW LEVEL
THETA-E AXIS WILL BE SHIFTED EASTWARD THIS AFTERNOON WHICH WILL
GREATLY IMPROVE THE CONVECTION CHANCES FOR US. THIS WILL LEAD TO
HEALTHY INSTABILITIES PROGGED TO BE BETWEEN 2000 AND 3000 J/KG
WITHIN THIS AXIS. ADDITIONALLY...NEAR SEASONAL AVERAGE PRECIPITABLE
WATER VALUES WILL CLIMB TO AROUND 120-140 PERCENT OF NORMAL. INITIAL
MOVEMENT OF CONVECTION WILL BE TO THE SOUTHEAST. TOWARDS THE
DIMINISHING STAGE OF CONVECTION...MOVEMENT WILL BE MORE TOWARDS THE
SOUTH WITH 850MB WINDS VEERING TO THE SOUTHWEST. THERE WILL STILL BE
SOME FLOW IN THE COLUMN BEFORE THE RIDGE BUILDS INTO THE AREA NEXT
WEEK. ALTHOUGH...CHANCES OF SEVERE REMAIN LOW.

LOW STRATUS WAS BEGINNING TO FORM OVER THE ROLLING PLAINS EARLY THIS
MORNING AND IS ANTICIPATED TO INCREASE IN COVERAGE BY DAYBREAK.
MODELS ARE LESS BULLISH WITH THIS CLOUD DECK STICKING AROUND THE
ROLLING PLAINS THROUGH MUCH OF THE AFTERNOON.
THEREFORE...TEMPERATURES SHOULD BE MUCH WARMER FOR TODAY.

LONG TERM...
THERE ARE FEW CONCERNS THIS FORECAST AS SOLUTIONS IN AGREEMENT
THAT A 6000-ISH METER RIDGE AT THE 500 MILLIBAR LEVEL WILL BUILD
JUST TO OUR NORTHWEST CENTERED OVER SOUTH-CENTRAL COLORADO EARLY
NEXT WEEK. THIS SUPPORTS STILL THE GENERAL WARMTH AND DRYNESS IN
GOING FORECAST REQUIRING LITTLE CHANGE. A COUPLE THINGS TO WATCH
INCLUDE A WAVE ROUNDING THE UPPER RIDGE LATE SUNDAY IN TANDEM WITH
ANOTHER WEAK WAVE CROSSING THE NORTHERN TIER...PULLING A BIT MORE
PRECIPITABLE WATER THROUGH WESTERN ZONES INTO THE PANHANDLE. WE
HAVE ADDED LOW MENTION OF THUNDERSTORMS LATE SUNDAY WESTERN BORDER
AREA AS UPPER HEIGHTS NOT YET COMPLETELY DISMISSIVE OF STORM
CHANCES THOUGH FLOW WILL BE QUITE WEAK. BY WEDNESDAY...THIS SAME
SHORTWAVE DUO STILL APPEARS TO DEEPEN OVER THE GREAT LAKES AND
MISSOURI VALLEY MORE PER THE ECMWF THAN GFS...DRAGGING A STRONGER
COLD FRONT SOUTHWARD INTO OUR AREA. HEIGHTS ALOFT SHOULD QUASH

.AVIATION...
SMALL THUNDERSTORM COMPLEX PROPAGATING SOUTH-SOUTHEASTWARD THROUGH
EASTERN NM SHOULD REMAIN WELL WEST OF THE TERMINALS LATE TONIGHT.
HOWEVER...RELATIVELY MOIST UPSLOPE FLOW HAS ALREADY RESULTED IN
DEWPOINT DEPRESSION FALLING INTO THE SINGLE DIGITS. THIS RAISES
CONCERN FOR POTENTIAL LOW CLOUD DEVELOPMENT AT THE TERMINALS LATER
TONIGHT...AND HAVE INSERTED TEMPO GROUPS TO ACCOUNT FOR THIS.
THINK CIGS/BR WILL MOST LIKELY BE IN THE MVFR CATEGORY...THOUGH
IFR CONDITIONS COULD OCCUR TOO. ANY SUB-VFR CIGS SHOULD
SCATTERED/LIFT BY MID TO LATE MORNING...WITH VFR CONDITIONS
THEREAFTER. ADDITIONALLY...AFTERNOON THUNDERSTORMS ORIGINATING
OVER THE HIGHER TERRAIN OF NM MAY MAKE A STRONGER EASTWARD PUSH
SATURDAY EVENING...PERHAPS EVENING THREATENING KLBB TOWARD THE END
OF THE TAF PERIOD. THAT SAID...CONFIDENCE IN CONVECTION DIRECTLY
AFFECTING THE TERMINALS TOMORROW EVENING IS TOO LOW TO INCLUDE
ATTM.

.PREV DISCUSSION... /ISSUED 251 PM CDT FRI JUL 18 2014/

SHORT TERM...
THE SYNOPTIC PATTERN LATE THIS AFTN WAS COMPOSED OF UA TROUGHINESS
ACROSS THE UPPER MISSISSIPPI VALLEY WITH UA RIDGING ACROSS THE
DESERT SW...LEADING TO NW FLOW ALOFT PREVAILING ACROSS THE SOUTHERN
PLAINS. LOOKING AT THE SFC...THE UPSLOPE SFC REGIME THAT ENCOMPASSED
THE SOUTHERN PLAINS EARLIER THIS MORNING...HAS SINCE VEERED TO THE
S-SE ON THE CAPROCK...WITH LIGHT AND VARIABLE/NE WINDS OCCURRING OFF
THE CAPROCK. LOW CLOUDS HAVE SLOWLY ERODED FROM SOUTH TO
NORTH...SETTING UP AN OBVIOUS TEMP GRADIENT OF UPPER 70S TO LOWER
80S ACROSS THE SRN LOCALES TO LOWER-MIDDLE 70S ELSEWHERE. WILL
EXPECT CLOUD DECKS TO LIFT THROUGHOUT THE REMAINDER OF THE AFTN INTO
EARLY EVENING. OROGRAPHIC EFFECTS AND DAYTIME DESTABILIZATION HAVE
RESULTED IN THE DEVELOPMENT OF THUNDERSTORMS ACROSS CNTRL AND NE NEW
MEXICO. NW FLOW ALOFT COULD AID IN STORMS NEARING THE FAR SW TX
PANHANDLE/NW SOUTH PLAINS LATER THIS EVENING AND TONIGHT...HOWEVER
RELATIVELY WEAK STEERING FLOW COULD MITIGATE THIS OCCURRENCE FROM
COMING TO PASS.

OVERNIGHT INTO TOMORROW MORNING...LIGHT S-SE SFC WINDS WILL
ENCOURAGE CONTINUAL LOW LEVEL MOISTURE AND THUS...THE DEVELOPMENT OF
LOW CLOUDS AND/OR FOG MAY ONCE AGAIN BECOME REALIZED. TOMORROW
AFTN...THE UA RIDGE CENTERED WEST OF THE REGION WILL SLOWLY EXPAND
EAST AND PROMOTE RISING 500 MB HEIGHTS AND THICKNESS VALUES...HENCE
RESULTING IN WARMER TEMPS /UPPER 80S TO LOWER 90S/. NW FLOW ALOFT
WILL ENDURE AND STORMS ACROSS THE HIGHER TERRAIN OF EAST NEW MEXICO
MAY ONCE AGAIN MAKE A RUN FOR THE FAR WEST AND NW SOUTH PLAINS.
STEERING FLOW IS A TAD BETTER AND WILL THEREFORE MAINTAIN A SLIGHT
CHANCE ACROSS THE AFOREMENTIONED AREA.

LONG TERM...
WEATHER IN THE LONG TERM IS EXPECTED TO BE QUIET THROUGH THE NEXT
WEEK. HIGH PRESSURE WILL BE POSITIONED TO OUR WEST PUTTING US IN
WEAK NORTHWESTERLY FLOW FOR LATE SATURDAY. MODELS HAVE BEEN FAIRLY
CONSISTENT WITH MOVING A WEAK SHORTWAVE AROUND THE EDGE OF THE HIGH
DEVELOPING SOME CONVECTION ON THE MOUNTAINS OF NORTHERN NM AND
MOVING THE SHOWERS AND THUNDERSTORMS INTO OUR NORTHWEST ZONES ALONG
A LEE TROF. DRY AIR AND ACTUAL UPPER LEVEL FORCING REMAIN IN
QUESTION BUT FOR NOW I SEE NO NEED TO ADJUST POPS THAT ARE IN PLACE
FOR SATURDAY NIGHT INTO EARLY SUNDAY MORNING. THROUGH NEXT WEEK WE
CONTINUE TO STAY ON THE EASTERN EDGE OF THE AFOREMENTIONED UPPER
LEVEL HIGH. THE GFS KEEPS THE HIGH JUST A BIT WEAKER THAN THE
ECMWF...WHO HAS MAX HEIGHTS OVERHEAD AT 600DM...AND KEEPS HEIGHTS
AVERAGED BETWEEN 594 TO 597DM. THIS WILL KEEP TEMPS NICE AND TOASTY
AT THE SURFACE WITH HIGHS IN THE UPPER 90S BEING EASILY OBTAINABLE.
AREAS OFF THE CAPROCK WILL BE WARMER PUSHING INTO THE LOW 100S AT
TIMES. THE RECENT RAINS WILL HELP ADD A SAUNA EFFECT OUT EAST AS
WELL. ONE ITEM OF INTEREST IS A WEAK FRONT THAT IS BROUGHT SOUTHWARD
BY BOTH GLOBAL MODELS BY MID WEEK. BOTH THE ECMWF AND THE GFS DRAPE
THE FRONT ACROSS THE REGION AND DEVELOP SOME PRECIP ALONG THE
FRONTAL BOUNDARY. THE BIGGEST DIFFERENCES BETWEEN THE 2 MODELS ARE
THAT THE GFS HAS THE UPPER LEVEL HIGH CENTERED CLOSER OVERHEAD THAN
THE ECMWF AND KEEPS THE FRONT TO THE NORTH OF THE FA. SINCE THE
ECMWF HAS THE CENTER OF THE HIGH FARTHER WEST...THAT WILL HELP PUSH
THE FRONT FARTHER SOUTH AND INTO THE FA. SINCE MOISTURE WILL BE
LINGERING AT THE SURFACE...GENERAL CONVECTIVE DEVELOPMENT SHOULD NOT
BE HARD TO COME BY. THIS WOULD ALSO COOL TEMPS BY A FEW DEGREES BUT
STILL KEEP US IN THE 90S. I HAVE OPTED TO RAISE POPS BUT KEEP THEM
BELOW MENTION DUE TO RUN TO RUN INCONSISTENCIES. BY NEXT WEEKEND THE
RIDGE WILL BEGIN TO FLATTEN GIVING WAY TO MORE ZONAL FLOW AS A LOW
SKIRTS THE CA/US BORDER. THIS WILL SLOWLY PUSH THE RIDGE FARTHER
WESTWARD AND OPEN UP A CHANCE FOR MORE NORTHWESTERLY FLOW AND
POSSIBLE A SHOT AT RAIN.

NATIONAL WEATHER SERVICE LUBBOCK TX
646 PM CDT FRI JUL 18 2014

.AVIATION...
VFR CONDITIONS HAVE DEVELOPED AT THE TERMINALS THIS AFTERNOON AND
THEY ARE EXPECTED TO BE THE PREDOMINATE MODE THROUGH THE TAF
CYCLE. THERE IS A LOW CHANCE OF A RETURN OF MVFR TO IFR CIGS
TOWARD DAWN AT KLBB AND KCDS...BUT CONFIDENCE IN THIS IS TOO LOW
FOR INCLUSION IN THE TAFS ATTM. OTHERWISE...WINDS WILL REMAIN ON
THE LIGHT SIDE VEERING MORE SOUTHERLY ON SATURDAY. ANY CONVECTION
SHOULD REMAIN WELL TO THE WEST AND NORTHWEST OF THE TERMINALS
THROUGH TONIGHT AND AGAIN SATURDAY AFTERNOON.

&&

.PREV DISCUSSION... /ISSUED 251 PM CDT FRI JUL 18 2014/

SHORT TERM...
THE SYNOPTIC PATTERN LATE THIS AFTN WAS COMPOSED OF UA TROUGHINESS
ACROSS THE UPPER MISSISSIPPI VALLEY WITH UA RIDGING ACROSS THE
DESERT SW...LEADING TO NW FLOW ALOFT PREVAILING ACROSS THE SOUTHERN
PLAINS. LOOKING AT THE SFC...THE UPSLOPE SFC REGIME THAT ENCOMPASSED
THE SOUTHERN PLAINS EARLIER THIS MORNING...HAS SINCE VEERED TO THE
S-SE ON THE CAPROCK...WITH LIGHT AND VARIABLE/NE WINDS OCCURRING OFF
THE CAPROCK. LOW CLOUDS HAVE SLOWLY ERODED FROM SOUTH TO
NORTH...SETTING UP AN OBVIOUS TEMP GRADIENT OF UPPER 70S TO LOWER
80S ACROSS THE SRN LOCALES TO LOWER-MIDDLE 70S ELSEWHERE. WILL
EXPECT CLOUD DECKS TO LIFT THROUGHOUT THE REMAINDER OF THE AFTN INTO
EARLY EVENING. OROGRAPHIC EFFECTS AND DAYTIME DESTABILIZATION HAVE
RESULTED IN THE DEVELOPMENT OF THUNDERSTORMS ACROSS CNTRL AND NE NEW
MEXICO. NW FLOW ALOFT COULD AID IN STORMS NEARING THE FAR SW TX
PANHANDLE/NW SOUTH PLAINS LATER THIS EVENING AND TONIGHT...HOWEVER
RELATIVELY WEAK STEERING FLOW COULD MITIGATE THIS OCCURRENCE FROM
COMING TO PASS.

OVERNIGHT INTO TOMORROW MORNING...LIGHT S-SE SFC WINDS WILL
ENCOURAGE CONTINUAL LOW LEVEL MOISTURE AND THUS...THE DEVELOPMENT OF
LOW CLOUDS AND/OR FOG MAY ONCE AGAIN BECOME REALIZED. TOMORROW
AFTN...THE UA RIDGE CENTERED WEST OF THE REGION WILL SLOWLY EXPAND
EAST AND PROMOTE RISING 500 MB HEIGHTS AND THICKNESS VALUES...HENCE
RESULTING IN WARMER TEMPS /UPPER 80S TO LOWER 90S/. NW FLOW ALOFT
WILL ENDURE AND STORMS ACROSS THE HIGHER TERRAIN OF EAST NEW MEXICO
MAY ONCE AGAIN MAKE A RUN FOR THE FAR WEST AND NW SOUTH PLAINS.
STEERING FLOW IS A TAD BETTER AND WILL THEREFORE MAINTAIN A SLIGHT
CHANCE ACROSS THE AFOREMENTIONED AREA.

LONG TERM...
WEATHER IN THE LONG TERM IS EXPECTED TO BE QUIET THROUGH THE NEXT
WEEK. HIGH PRESSURE WILL BE POSITIONED TO OUR WEST PUTTING US IN
WEAK NORTHWESTERLY FLOW FOR LATE SATURDAY. MODELS HAVE BEEN FAIRLY
CONSISTENT WITH MOVING A WEAK SHORTWAVE AROUND THE EDGE OF THE HIGH
DEVELOPING SOME CONVECTION ON THE MOUNTAINS OF NORTHERN NM AND

BKN-OVC MVFR CLOUD DECKS PERSISTED AT BOTH TAF SITES THIS
AFTERNOON...AS LOW CLOUD DECKS WERE SLOW TO LIFT. COMPUTER MODELS
HINT AT LOW CLOUDS SCOURING OUT/LIFTING TO VFR BY MID-DAY.
OTHERWISE...E-SE WINDS WILL ENSUE WITH HINTS OF THE RETURN OF MVFR

PREV DISCUSSION... /ISSUED 423 AM CDT FRI JUL 18 2014/

SHORT TERM...
A FAVORABLE SET UP WILL BE IN PLACE FOR CONVECTION ON THE HIGHER
TERRAIN OF NEW MEXICO. HOWEVER...THIS CONVECTION WILL LIKELY
STRUGGLE TO REACH WEST TEXAS. EASTERLY WINDS THIS MORNING WILL VEER
TO THE SOUTHEAST THIS AFTERNOON. PRECIPITABLE WATER VALUES WILL ALSO
DECREASE TODAY BUT WILL STILL BE AROUND SEASONAL VALUES. THIS MAY BE
A LITTLE MISLEADING THOUGH WITH A SIGNIFICANT DRY AIR INTRUSION AT
MID AND UPPER LEVELS. LOW LEVEL MOISTURE WILL REMAIN ABUNDANT WITH
HIGH INSTABILITY TO THE WEST OF THE REGION. HOWEVER...THIS
INSTABILITY WILL QUICKLY DECREASE INTO WEST TEXAS COINCIDENT WITH THE
LOW LEVEL THETA-E AXIS. FURTHERMORE...HEIGHT RISES TODAY WILL ACT TO
SUPPRESS CONVECTION.

LOW STRATUS THIS MORNING IS SHOWING INDICATIONS IN MODEL GUIDANCE
THAT IT WILL HANG ONTO THE ROLLING PLAINS AT LEAST THROUGH THE EARLY
AFTERNOON. THIS WILL LEAD TO ANOTHER ABNORMALLY COOL DAY FOR THE
ROLLING PLAINS AS WELL AS THE REST OF THE AREA. LOW CLOUDS MAY MAKE
A RUN AT THE AREA FOR SATURDAY MORNING FROM THE SOUTHEAST BUT LOOKS
TO ENCOMPASS A SMALLER PORTION OF THE REGION.

LONG TERM...
EXCELLENT AGREEMENT BETWEEN SOLUTIONS ON THE BUILDING UPPER LEVEL
RIDGE JUST TO OUR NORTHWEST IN THE DAYS AHEAD...PEAKING WEDNESDAY-
ISH WITH NEARLY 6000 METERS OF HEIGHT AT THE 500 MB LEVEL. THIS
WILL LEAD TO OBVIOUS WARMING AND DRY PERIOD LATE IN THE WEEKEND
INTO NEXT WEEK...THOUGH FOR LATE SATURDAY AND EVEN PERHAPS LATE
SUNDAY IN THE FAR NORTHWEST...THERE MAY YET BE JUST ENOUGH FLOW
WITH ATMOSPHERE STILL ONLY WEAKLY CAPPED FOR AT LEAST LOW THUNDER
CHANCES. SATURDAY WILL SEE LOW LEVEL CONVERGENCE AS WELL WITH
MODEST SURFACE TROUGH PERHAPS LEADING TO THUNDERSTORM GENERATION
NOT TOO FAR WEST INTO EASTERN NEW MEXICO...BOOSTING OPPORTUNITY
JUST SLIGHTLY. HEAT INDICES WILL INCREASE BY TUESDAY AND WEDNESDAY
IN THE ROLLING PLAINS...THOUGH LATEST CALCULATIONS REMAIN SHORT OF
ACTION LEVELS. WE CONTINUE TO LEAN IN GENERAL SLIGHTLY UNDER MOST
GUIDANCE MAXIMUM TEMPERATURES DURING THIS PERIOD. EASTERLY
COMPONENTS ALSO EXPECTED TO SLIGHTLY INCREASE LATE NEXT WEEK WITH
THE RIDGE CENTER TO OUR NORTHWEST WHICH SHOULD LIMIT THE HEAT FOR
MOST OF OUR AREA. RMCQUEEN
