AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
417 AM CST WED FEB 2 2011

.DISCUSSION...
COMBINATION OF WIND AND VERY COLD TEMPERATURES WILL PRODUCE WIND
CHILL WELL BELOW ZERO IN A LOT OF AREAS OVER THE NEXT 24 HOURS.
SO NO PLANS TO ADJUST WIND CHILL ADVISORY. CURRENT WIND CHILLS IN
WARNING AREA RANGE FROM -17 TO -21 BELOW AND WILL LIKELY LET WARNING
EXPIRE AROUND MID-MORNING.

SOME LIGHT ECHOS THIS MORNING BETWEEN LBB/MAF BUT ECHOS ARE HAVING
A HARD TIME REACHING FAR WESTERN TEXAS COUNTIES. GFS INDICATES SOME
WEAK WAA AROUND 7H LATER THIS MORNING BUT EXPECT FLURRIES AT
BEST. WITH TROUGH/UPPER LOW MOVING FARTHER SOUTH TODAY...BETTER
OPPORTUNITY FOR CLOUD COVER SHOULD BE ACROSS WESTERN PARTS OF FA.

VERY COLD AIR THAT ORIGINATED OVER THE YUKON/NORTHWEST TERRITORIES
WILL BE SLOW TO MODIFY OVER THE NEXT FEW DAYS. WITH LIGHTER WINDS
AND FEW CLOUDS...AT LEAST NORTH...TEMPS SHOULD DIP WELL BELOW ZERO
WITH DECENT SNOW COVER. A NORTHERLY WIND COMPONENT AT OKC IS NOT
A FAVORABLE WIND FOR LOW MIN TEMPERATURES HOWEVER.

NEXT TROUGH/UPPER LOW WILL LIFT ACROSS NORTH TEXAS/SOUTHEAST
OKLAHOMA ON FRIDAY. LOW CLOUDS WILL LIFT NORTH INTO AT LEAST
SOUTH CENTRAL/SOUTHEAST OKLAHOMA AHEAD OF THIS FEATURE...BUT
LITTLE IN ANY PRECIP SHOULD OCCUR.

SATURDAY INTO SUNDAY SHOULD SEE TEMPERATURES WARM TO NEAR NORMAL
...BEFORE ANOTHER STRONG FRONT APPROACHES SUNDAY NIGHT INTO
MONDAY. EC MUCH FASTER WITH THE FRONT...BUT ENSEMBLE MEAN GIVES
SOME SUPPORT TO SLOWER 00Z GFS. SHORTWAVE THAT APPROACHES IN
NORTHWEST FLOW/ AND DECENT FRONTOGENETIC FORCING WILL SUPPORT
SOME SNOW/RAIN. SNOWFALL AMOUNTS WITH THIS SYSTEM WILL LIKELY
BE ON THE LIGHTER SIDE. DID ADJUST TEMPS DOWN SEVERAL DEGREES
FOR HIGHS ON TUESDAY.

458 PM CST WED FEB 2 2011

.DISCUSSION...COLD CONTINUES THIS AFTERNOON WITH TEMPS STRUGGLING
TO GET OUT OF THE TEENS. WINDS HAVE BEGUN TO DIMINISH BUT STILL
SHOULD BE ENOUGH WIND WITH THE FALLING TEMPS TO KEEP WIND CHILL
ADVY IN PLACE. LOW TEMPS TONIGHT MAY BE AFFECTED BY MID/HIGH
CLOUDS ASSOCIATED WITH UPPER SYSTEM MOVING THROUGH NM. OTRW WILL
KEEP LOW POPS IN THE SE FOR FRIDAY AS PREVIOUSLY MENTIONED UPPER
SYSTEM LIFTS NEWD THROUGH TX. TEMPS SHOULD WARM LATE IN THE WEEK
WITH READINGS APPROACHING NORMAL BY THE WEEKEND.

HOWEVER...WARM UP WILL BE SHORT LIVED WITH ANOTHER SHOT OF COLD AIR
EXPECTED BY EARLY NEXT WEEK. WILL ALSO KEEP THE POPS IN SUNDAY
NIGHT INTO MONDAY NIGHT AS S/W ZIPS THROUGH IN NW FLOW.

455 AM CST THU FEB 3 2011

.DISCUSSION...
THE SNOW PACK CONTINUES TO KEEP SHORT RANGE MODELS BIASED TOO
WARM... SO TEMPERATURE GRIDS HAVE BEEN ADJUSTED MUCH COOLER.
AN UPPER LOW WAS SPINNING ACROSS NEW MEXICO. NAM AND ECMWF ARE IN
GOOD AGREEMENT WITH THE LOW DIGGING INTO OLD MEXICO... THEN
LIFTING NORTHEAST ACROSS WESTERN AND NORTHERN TEXAS ON FRIDAY. THE
ARRIVAL OF THE UPPER LOW WILL BRING LOW POPS OF -SN ACROSS
SOUTHEASTERN OKLAHOMA FOR FRIDAY. SATURDAY WILL BE A BRIEF
WARM UP... AS THE ARCTIC AIR WILL LIFT TO THE NORTH AND EAST.
HOWEVER... NORTHWEST FLOW ALOFT WILL BRING ANOTHER DISTURBANCE INTO
OUR AREA SATURDAY NIGHT... WITH ANOTHER BLAST OF COLD AIR
ARRIVING. OMEGA FIELDS SHOW EVIDENCE OF WEAK UPWARD FORCING
ASSOCIATED WITH THE DISTURBANCE TO PRODUCE ANOTHER ROUND OF -SN
ACROSS PORTIONS OF THE AREA. HOWEVER... ISENTROPHIC FIELDS AT THIS
TIME ARE NOT VERY IMPRESSIVE... AND SHOW STRONG DOWNGLIDE BY 12Z
SUNDAY. GFS BRINGS THE PRECIPITATION FURTHER SOUTH INTO OUR
AREA... WHILE ECMWF KEEPS IT ACROSS OUR NORTH. AS A RESULT...
SLIGHTLY HIGHER POPS ARE ACROSS NORTHERN OKLAHOMA FOR SUNDAY.

AREA FORECAST DISCUSSION

238 PM CST THU FEB 3 2011

.DISCUSSION...
UPPER LOW OVER SOUTHERN NM/NORTHERN OLD MEXICO WILL MOVE EAST
ACROSS THE SOUTHERN PLAINS TONIGHT AND FRIDAY. THIS SYSTEM HAS
BROUGHT MID-LEVEL CLOUDS TO PARTS OF THE FA WHICH ARE EXPECTED TO
PERSIST OVERNIGHT INTO FRIDAY. WITH THE CLOUD COVER TEMPERATURES
TONIGHT WILL REMAIN SLIGHTLY WARMER THAN LAST NIGHT IN MANY
LOCATIONS. HOWEVER... WILL STILL BE COLD WITH LOWS RANGING FROM
AROUND ZERO IN THE NORTH TO THE LOW TEENS ALONG THE RED RIVER. THE
UPPER LOW WILL ALSO BRING A CHANCE OF LIGHT SNOW OR SNOW FLURRIES
TO APPROXIMATELY THE SOUTHEAST HALF OF THE FA BY FRIDAY. SOME
ACCUMULATIONS WILL BE POSSIBLE. HOWEVER... THESE ARE NOT EXPECTED
TO BE LARGE WITH THE GREATEST AMOUNTS... MAYBE UP TO AN INCH...
EXPECTED IN SE PORTIONS OF THE FA. TEMPERATURES WILL CONT TO
GRADUALLY WARM FRIDAY AND SATURDAY WITH MOST PLACES EXPECTED TO
CLIMB ABOVE FREEZING SATURDAY.

NW FLOW ALOFT WILL AFFECT THE SOUTHERN PLAINS THIS WEEKEND INTO
EARLY NEXT WEEK. MODELS SHOW SEVERAL DISTURBANCES THAT WILL MOVE
THROUGH THIS FLOW... BRINGING SEVERAL CHANCES FOR LIGHT SNOW/SNOW
FLURRIES SAT NIGHT THROUGH SUNDAY NIGHT. SNOW ACCUMULATIONS OF AN
INCH OR TWO WILL BE POSSIBLE IN SOME LOCATIONS BY MONDAY BUT NO
SIGNIFICANT PRECIP IS EXPECTED. A COLD FRONT WILL ALSO MOVE ACROSS
THE REGION SUNDAY BRINGING ANOTHER ROUND OF COLD AIR THAT WILL
CONTINUE INTO THE MIDDLE OF NEXT WEEK.

MORE SIGNIFICANT WINTER PRECIPITATION MAY BE POSSIBLE TUESDAY AND
WEDNESDAY. MODELS SHOW A SHORTWAVE MOVING SE TOWARDS THE SOUTHERN
PLAINS TUESDAY THEN MOVING ACROSS THE REGION WEDNESDAY. RIGHT NOW
THIS SYSTEM DOES NOT LOOK AS STRONG AS THE ONE FROM EARLIER THIS
WEEK. HOWEVER... THE SYSTEM COULD STILL PRODUCE SEVERAL INCHES OF
SNOW IN SOME LOCATIONS ALONG WITH GUSTY WINDS AND COLD WIND CHILLS.
BEING SIX TO SEVEN DAYS AWAY MANY THINGS CAN CHANGE BUT RIGHT NOW
TUESDAY AND WEDNESDAY LOOKS LIKE THE NEXT CHANCE FOR IMPACTFUL SNOW
ACCUMULATIONS IN PARTS OF THE FA.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
436 AM CST FRI FEB 4 2011

.DISCUSSION...
TOUGH CALL ON HEADLINES IN SE OK THIS MORNING. SNOW LIKELY TO BE
LIGHT AND POWDERY AND WIND WILL HAVE MINIMAL EFFECT AS FAR AS ANY
BLOWING. BUT THERE IS ENOUGH CONCERN REGARDING THE INTENSITY AND
TRACK OF THE UPPER LOW OVER TX... AND EXPECTED HIGH SNOW-TO-WATER
RATIOS IMPROVE THE CHANCES OF AT LEAST SOME LOCAL 2-3 INCH
AMOUNTS. WE WILL ISSUE AND ADVISORY THROUGH 22Z FOR A FEW ZONES IN
SE AND FAR SCENTRAL OK. SNOW SHOULD TAPER OFF AND END BY THIS EVENING.

LEANING TOWARD THE COOL SIDE OF GUIDANCE TEMPS NEXT COUPLE DAYS...
AT LEAST WHERE THERE IS SNOW COVER. THIS MEANS HIGHS MUCH LOWER
THAN THE NAM-BASED MET GUIDANCE. INTERESTING THAT THE NAM12 SFC-T
FIELDS CAPTURE THE SNOW FIELD AND KEEP MOST OF IT IN THE LOW 30S
OR LESS EACH DAY THROUGH MONDAY... BUT THE MET HAS OKC UP TO 48
SATURDAY. KEEPING MOST OF THE SNOW AREAS IN THE 30S EVEN INTO
SATURDAY BUT AT LEAST MOST AREAS FINALLY SHOULD CREEP ABOVE
FREEZING FOR A WHILE.

SYSTEM SWINGING QUICKLY THROUGH FROM THE NW SAT NIGHT AND SUPER
BOWL SUNDAY NEEDS TO BE WATCHED FOR ADDITIONAL ACCUMULATIONS.
HEAVY AMOUNTS APPEAR UNLIKELY GIVEN UNFAVORABLE LOW-LEVEL WINDS
AND GENERAL LACK OF MOISTURE... BUT MODELS SUPPORT A BAND/SWATH OF
AT LEAST LIGHT SNOW STREAKING ESE ACROSS MAINLY CENTRAL/S OK. GFS
NOW DROPS 4-7 INCHES OVER SW OK. POPS HAVE BEEN INCREASED OVER
MOST OF THE AREA BUT FOR NOW ARE BEING HELD IN THE 30-40 RANGE.

YET ANOTHER SYSTEM DROPS SE TOWARD THE AREA TUE-WED COINCIDING
WITH YET ANOTHER ARCTIC AIR MASS INVADING THE AREA. MIDWEEK
TEMPERATURES HAVE BEEN LOWERED FROM THE LATEST GFS-MOS GUIDANCE -
CONSIDERABLY IN SOME CASES. ECMWF AND GFS AGREE ON THE ARCTIC
INTRUSION COMMENCING ON TUESDAY AND GOING INTO FULL GEAR BY
TUESDAY NIGHT WITH MORE STRONG WINDS AND BRUTAL WIND CHILLS... AND
PROBABLY MORE SNOW AND BLOWING SNOW.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
328 PM CST FRI FEB 4 2011

.DISCUSSION...THERE IS MUCH INTEREST IN WHAT WILL BE A CONTINUED
COLD PATTERN FOR THE NEXT WEEK...WITH AT LEAST TWO MORE
OPPORTUNITIES FOR SNOW.

AN UPPER LOW TRACKING THROUGH OKLAHOMA AND NORTH TEXAS TODAY...HAD
LITTLE OPPORTUNITY TO AMPLIFY...GIVEN THAT IT WAS OVERRIDING A
STABLE COLD DOME. BUT THE BROAD LARGE SCALE ASCENT...COUPLED WITH
VERY COLD UPPER LEVEL TEMPERATURES...RESULTED IN A DENDRITIC SNOW
GROWTH PROCESS...AND GENEROUS SNOWFALL OF 1-3 INCHES NEAR INTERSTATE
35...AND 3-5 INCHES FARTHER EAST. THE LOW WAS SLOW MOVING...WITHOUT
A REAL KICKER SYSTEM. IT WAS OPENING UP...THOUGH...AND WHATEVER SNOW
FALLS THIS EVENING SHOULD BE LIGHTER AND LIGHTER...WITH LITTLE
ADDITIONAL ACCUMULATION.

FLOW WILL THEN RESPOND TO AN APPROACHING DIP IN THE NORTHERN JET
STREAM. INCREASED WESTERLY FLOW AT ALL LEVELS SHOULD YIELD CLEARING
OVERNIGHT. WITH DRY AIR ADVECTING OVER THE SNOW FIELD IN A DOWNSLOPE
FASHION...SUSPECT THERE WILL NOT BE ANY SIGNIFICANT FOG...THOUGH
PATCHY SHALLOW FOG DUE TO MELTING/SUBLIMATION IS POSSIBLE. MID LEVEL
CLOUDS WILL INCREASE ON SATURDAY...BUT SKIES SHOULD BE AT LEAST
PARTLY SUNNY...WITH TEMPERATURES FORECAST ABOVE FREEZING FOR AT
LEAST A FEW MIDDAY HOURS.

THE NORTHERN STREAM CLIPPER SYSTEM THEN ARRIVES SATURDAY NIGHT AND
SUNDAY. IT HAS BEEN DIFFICULT TO EXTRACT THE MOST PERSISTENT AND
MEANINGFUL SIGNALS FROM THE MODELS REGARDING THIS SYSTEM. OUR
TAKE...HOWEVER...IS THAT WHATEVER LOW LEVEL WARMING TAKES PLACE
SATURDAY SHOULD BE QUICKLY REDUCED BY POST FRONTAL LIFT AND
EVAPORATIVE COOLING ASSOCIATED WITH THE CLIPPER SYSTEM. WE SHOULD
EXPERIENCE A MINIMAL PERIOD OF COLD LIGHT RAIN THAT WILL CHANGE
QUICKLY OVER TO SNOW. QPF IN THE NAM HAS BEEN LIGHT OR AT LEAST
INCONSISTENT...AS THE 18Z RUN NOW PAINTS A THIN STRIPE OF 1-3
INCHES. THE PATTERN OF HEIGHT FALLS...STEEP MID LEVEL LAPSE
RATES...AND LIFT IN THE DENDRITIC CRYSTAL ZONE...ARGUES TOWARD A
MORE WIDESPREAD ACCUMULATION OF SNOW THAT MAY AFFECT MOST IF NOT ALL
OF OUR FORECAST AREA. MAXIMUM AMOUNTS WOULD BE LOCATED NEAR THE
TRACK OF GREATER HEIGHT FALLS THROUGH WESTERN AND SOUTHERN OKLAHOMA
AND WESTERN NORTH TEXAS. WITH SUPPORT OF THE ECMWF AND GFS...WE
BUMPED SNOW GRIDS UP TO REFLECT 1-3 INCHES ACROSS THE REGION. WITH
SNOW TO LIQUID RATIOS LIKELY TO BE NEAR OR GREATER THAN AVERAGE...WE
WOULD NOT BE SURPRISED TO SEE LOCAL REPORTS OF 4 TO 5 INCHES MUCH
LIKE WE RECEIVED TODAY. SINCE THIS IS NOT UNTIL THE THIRD AND FOURTH
PERIODS...AND GIVEN SOME LACK OF MODEL CONVERGENCE...WE WILL NOT
ISSUE AN ADVISORY JUST YET...BUT SUSPECT ONE WILL BE NEEDED.
FORTUNATELY...WINDS SHOULD NOT BE TOO STRONG WITH THIS SYSTEM...BUT
GUSTS OVER 20 MPH ARE LIKELY.

AFTER A BRIEF AND LIMITED WARM UP ON MONDAY...WE SEE ANOTHER WEATHER
SYSTEM TAKE SHAPE TUESDAY AND WEDNESDAY. UNLIKE THE CLIPPER
SYSTEM...THIS ONE COMES IN AT A FLATTER ANGLE...AND HAS MORE
POTENTIAL TO UNDERGO AMPLIFICATION. THE DEGREE OF AMPLIFICATION WILL
DEPEND ON THE TIMING OF THE NEXT ARCTIC COLD FRONT ALONG WITH THE
STRENGTH OF THE UPPER WAVE...SOMETHING THAT WILL NOT BE SAMPLED BY
THE INLAND UPPER AIR NETWORK UNTIL MONDAY MORNING. THEREFORE...THERE
IS A LARGER AMOUNT OF UNCERTAINTY REGARDING THIS SYSTEM. WE ARE
CONFIDENT...HOWEVER...THAT THE SYSTEM WILL BRING VERY COLD WEATHER
AND INCREASED WINDS BY WEDNESDAY...AND THAT SOME SNOW ACCUMULATION
IS LIKELY OVER PART OR MOST OF THE REGION. THE 12Z GFS REPRESENTS ONE
EXTREME...WITH A VERY EARLY ARRIVAL OF COLD AIR AND LITTLE
AMPLIFICATION OF THE UPPER WAVE...WHILE THE 12Z ECMWF REPRESENTS
ANOTHER EXTREME...WITH THE SURFACE AND UPPER FEATURES ACTING IN
CONCERT TO GENERATE A STRONG WINTER STORM. WITH THE GFS TENDENCY TO
MOVE SYSTEMS TOO QUICKLY...WE LEANED CLOSER TO THE ECMWF IN
SPREADING HIGH CHANCE POPS AND GREATER WIND SPEEDS INTO WEDNESDAY.
FOLLOWING THE ARCTIC FRONT...REGARDLESS OF THE INTENSITY OF
SNOWFALL...THE COLD AIR IS LIKELY REMAIN IN PLACE THROUGH THE END OF
NEXT WEEK. AGAIN...THE STORM MAY COME INTO BETTER FOCUS OVER THIS
WEEKEND...BUT CERTAINLY BY MONDAY...AS THE UPPER TROUGH MOVES INLAND.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
424 AM CST SAT FEB 5 2011

.DISCUSSION...
DOWNSLOPE FLOW AND LACK OF SNOW COVER SHOULD ALLOW NW AND FAR W OK
TO WARM UP TODAY. ELSEWHERE IT WILL BE A STRUGGLE BECAUSE OF THE
SNOW... BUT MOST AREAS SHOULD GET ABOVE FREEZING FOR THE FIRST
TIME SINCE MONDAY OR MONDAY NIGHT.

CLOUDS INCREASING TODAY AND TONIGHT AHEAD OF NEXT SYSTEM
APPROACHING FROM THE NW. ASSOCIATED COLD FRONT MOVES THROUGH
TONIGHT WITH LITTLE MORE THAN A WIND SHIFT... BUT THE UPPER SYSTEM
STILL COULD LAY OUT A STREAK OF LIGHT PRECIP TONIGHT INTO
SUNDAY... MOST LIKELY AFFECTING NW/NCENTRAL TX AND S OK. NEW NAM
HAS A NARROW BAND OF 1-3 INCH SNOW CENTERED NEAR THE RED RIVER
FROM LATE TONIGHT THROUGH EARLY EVENING SUNDAY. GFS HAS A SIMILAR
BAND WHILE ECMWF KEEPS HIGHEST TOTALS OVER HIGHER TERRAIN OF
NM/WTX. ECMWF SCENARIO COULD BE RIGHT CONSIDERING THERE IS STILL
SOME QUESTION OF PRECIP TYPE DURING AT LEAST PART OF THE EVENT.
ALL IN ALL THIS LOOKS MOST LIKELY TO BE ANOTHER ADVISORY-TYPE
EVENT... BUT BECAUSE OF UNCERTAINTIES ON HOW FAR N-S THE
ACCUMULATION BAND WILL END UP WE WILL FOLLOW THE GUIDANCE TRENDS
AND BRING POPS BACK DOWN INTO THE HIGH-CHANCE RANGE. THIS ONE IS
LIKELY TO HAVE SOME EFFECT ON TRAVEL CONDITIONS FOR THOSE HEADING
DOWN TO THE SUPER BOWL FROM THE N ON SUNDAY.

THE NEXT SYSTEM DUE IN AROUND TUE-WED HAS THE POTENTIAL TO BE
MORE TROUBLESOME. ARCTIC HIGH IS POISED OVER NW CANADA TO DELIVER
ANOTHER SHOT OF UNSEASONABLY COLD AIR TO THE REGION BEGINNING TUE.
MODELS NOW IN BETTER AGREEMENT ON TIMING OF NEXT UPPER TROUGH.
PRECIP MAY START MON NIGHT N... BUT MORE LIKELY TO START TUE IN
MOST AREAS BEFORE PEAKING TUE NIGHT AND TAPERING OFF WED. THIS ONE
LIKELY TO FEATURE MORE WIND... MORE SNOW... AND COLDER AIR THAN
THE ONE TONIGHT/SUNDAY. THIS COULD BE ANOTHER RELATIVELY HIGH-
IMPACT EVENT. LATEST ECMWF HAS SFC WINDS 15-25KT ALL AREAS AND
6-10 INCHES OF SNOW OVER MUCH OF OK WITH SFC TEMPS INTO THE SINGLE
DIGITS BY WED. NEW GFS NOT AS BAD IN TERMS OF SNOW AND COLD BUT
STILL HAS 6+ INCHES OVER E OK AND TEMPS IN THE TEENS ENTIRE AREA.
WOULD ANTICIPATE A LOT OF MODEL-TO-MODEL AND RUN-TO-RUN CHANGES
NEXT SEVERAL DAYS. WE WILL NEED TO KEEP A CLOSE EYE ON THIS ONE.

COLDEST AIR SETTLES OVER THE AREA ALONG WITH THE SFC HIGH WED
NIGHT AND THU. AFTER THAT THERE ARE ACTUAL SIGNS THAT THE
E-PACIFIC UPPER HIGH/RIDGE... AND THUS THIS MISERABLE PATTERN...
WILL BREAK DOWN LATE NEXT WEEK. THIS EVENTUALLY WOULD ALLOW
TEMPERATURES TO RETURN TO NEAR OR EVEN ABOVE CLIMATOLOGY BY NEXT
WEEKEND.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
308 PM CST SAT FEB 5 2011

.DISCUSSION...
OBSERVATIONS CLEARLY INDICATE THAT SIGNIFICANT MODIFICATIONS HAVE
OCCURRED OVER THE REGION THE PAST 24 HOURS. U/A DATA SHOWS THAT
WE HAVE WARMED SOME 15C IN LOWER LEVELS OF ATMOSPHERE. WITH
INCOMING AIRMASS NOT ALL THAT COLD...WE MAY HAVE TROUBLE WITH
CONVERSION OF RAIN TO SNOW LATE TONIGHT AND TOMORROW
MORNING...WHEN LIFT IS AT ITS BEST. THE EXCEPTION WILL BE ANY
HEAVY BANDS OF PRECIPITATION WHERE MELTING EFFECTS WILL ALLOW
ENOUGH COOLING FOR ACCUMULATING SNOWS. COLD AIR SHOULD BECOME
DEEP ENOUGH TOWARD AND AFTER NOON TOMORROW FOR ALL SNOW...BUT THE
LIFT AND AMOUNT/INTENSITY OF PRECIPITATION WILL BE ON A DOWNWARD
TREND.

MANY FLIES IN THE OINTMENT HOWEVER. THERE ARE A LOT OF VARIABLES
TO ACCOUNT FOR LOWS TONIGHT AND PRECIP TYPE AND TEMPS TOMORROW. WE
HAVE THE REMAINING SNOW COVER. IMPRESSIVE DOWNSLOPE WARMING MOST
AREAS. INCREASING/THICKENING CLOUD COVER WHICH WILL MINIMIZE COOLING
TONIGHT. ALTHOUGH TEMPS WILL GET COLDER WHERE WE HAVE THE
REMAINING SNOW COVER...WE WILL WARM THE OVERNIGHT LOWS CLOSE TO
OR SLIGHTLY WARMER THAN GUIDANCE VALUES. WITH THAT BEING TYPED...WE
CANNOT ABSOLUTELY RULE OUT FREEZING DRIZZLE OR FREEZING RAIN OVER
SNOWPACK LATE TONIGHT AND EARLY TOMORROW MORNING. WITH MUCH...MUCH
HIGHER DEWPOINTS OWED TO EROSION OF SNOWPACK...AND MOST OF THEM
ARE NOW WARMER THAN THE MID-UPR 20S...WE ARE HEDGING SURFACE/BLYR
WET BULBS WILL STAY AOA FREEZING.

BRIEF WARM UP AGAIN AHEAD OF TUESDAY/WEDNESDAY STORM SYSTEM.
ALTHOUGH THIS APPEARS TO BE ANOTHER VERY COLD AND WINDY SYSTEM...WE
DO NOT SEE ANY SIGNS THAT THIS EVENT WILL BE AS STRONG AS LAST
WEEKS BLIZZARD.

AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE NORMAN OK
500 AM CST SUN FEB 6 2011

.DISCUSSION...
FOCUS TODAY IS ON THE S HALF OF THE AREA... S OF I-40... WHERE
PRECIP IS INCREASING AND MESONET METEOGRAMS SHOW TENDENCIES
SUGGESTIVE OF HEAT BURSTS. SFC COLD FRONT FINALLY MOVING S THROUGH
CENTRAL OK AND INTO NCENTRAL TX. GRADUAL COOLING MAY CHANGE PRECIP
OVER TO SNOW... BUT MUCH OF IT THIS MORNING MAY FALL AS RAIN OR A
RAIN/SLEET MIX WHERE HIGHER REFLECTIVITIES ARE BEGINNING TO
APPEAR. AT THIS TIME THIS STILL LOOKS LIKE A LOW-END EVENT WITH
PERHAPS AN INCH OR 2 OF SNOW OR SLEET/SNOW ACCUMULATIONS IN SOME
AREAS. NO HEADLINES ARE ANTICIPATED BUT WE OF COURSE WILL CONTINUE
TO MONITOR. ANY LINGERING PRECIP SHOULD BE OUT OF OUR SE ZONES BY
EARLY-MID EVENING.

MORE TROUBLE BREWING LATER IN THE WEEK AS ALL INDICATIONS POINT TO
ANOTHER SIGNIFICANT COLD INTRUSION AND ANOTHER PROBABLE HIGHER-END
WINTER STORM TUE INTO WED. 1042-MB SFC HIGH IS POISED OVER CANADA
TO MOVE S. THIS AIR WILL ARRIVE IN N/NW OK EARLY TUE MORNING
FOLLOWED BY FALLING DAYTIME TEMPS AND INCREASING N-NE WINDS BEHIND
THE ARCTIC FRONT AS IT MOVES INTO CENTRAL/SW OK BY EARLY EVENING
AND THROUGH THE REST OF THE AREA BY 12Z WED. BY THAT TIME WIND
CHILLS LIKELY TO BE BACK DOWN INTO THE -5 TO -20 RANGE N AND NW OF
THE FRONT.

SNOW MAY BEGIN IN NW OK TUE AFTERNOON BUT THE MAIN EVENT APPEARS
LIKELY TO BE TUE NIGHT INTO WED. WE CREATED SOME 6-H SNOW ACCUM
GRIDS BASED ROUGHLY ON MODEL SNOWFALL CONSENSUS AND FORECAST
QPF... WHICH YIELD WIDESPREAD 6-10 INCH STORM TOTALS ACROSS MOST
OF N AND CENTRAL OK BY WED EVENING. STANDARD DISCLAIMERS WILL
APPLY DUE TO PROBABLE VARIANCE IN THE MODEL FORECASTS OF THE TRACK
AND SPEED OF THE SYSTEM. REGARDLESS OF THE WHERE AND HOW-MUCH
ASPECTS OF THE SNOW... BLOWING/DRIFTING AND DANGEROUS COLD ARE
ALMOST CERTAIN TUE NIGHT AND WED. WINDS DO NOT LOOK AS STRONG WITH
THIS ONE SO ANOTHER BLIZZARD LIKE LAST WEEK IS UNLIKELY... BUT THE
IMPACT IS LIKELY TO BE SIGNIFICANT NONETHELESS.

LONGWAVE PATTERN DEAMPLIFIES AFTER THE TUE-WED STORM AND THE EAST-
PACIFIC RIDGE FINALLY GETS HAMMERED DOWN BY NEXT WEEKEND. PATTERN
SUPPORTS A DRY AND WARMER REGIME BY END OF NEXT WEEK... ALTHOUGH
RESIDUAL SNOW COVER AND THE RENOWNED STUBBORNNESS OF THESE ARCTIC
AIR MASSES TO LET GO WILL LIKELY SLOW THE WARMING.

310 PM CST SUN FEB 6 2011

.DISCUSSION...MAIN FOCUS IS ON THE MID WEEK WINTER STORM POTENTIAL.
THERE ARE...HOWEVER...SHORT TERM ISSUES AS WELL. A VERY GRADUAL
DIGGING OF COLD AIR INTO THE BASE OF AN UPPER TROUGH...HAS RESULTED
IN WEAK CYCLOGENESIS ALONG A SURFACE FRONT IN NORTHEAST TEXAS TODAY.
A BROAD BUT SOMEWHAT BROKEN FRONTAL BAND OF LIGHT RAIN EXISTS NORTH
OF THE FRONT. MODELS FORECAST LIFTING TO PERSIST THROUGH THE
EVENING...MAINLY FROM WICHITA FALLS TO SEMINOLE AND EASTWARD. WEAK
LOW LEVEL HEATING DURING THE DAY HAS KEPT THE PRECIPITATION AS
RAIN...BUT COLD ADVECTION AT 925-850 MB...COUPLED WITH SURFACE
COOLING...MAY ALLOW SOME SNOW TO THE GROUND THIS EVENING. WE DO NOT
EXPECT MUCH ACCUMULATION...IF ANY.

WHILE THE PRIMARY FRONT WAS IN NORTH TEXAS...A SECOND...BACKDOOR
ARCTIC...FRONT...WAS APPROACHING THROUGH KANSAS. ON MONDAY THIS
FRONT WILL SEPARATE SOMEWHAT MILD AIR IN OUR SOUTHWEST ZONES FROM
CHILLY AIR TO THE NORTH AND EAST. THIS WILL ALSO SERVE AS A FOCUS
FOR FRONTOGENESIS WHEN THE MID WEEK SYSTEM BEGINS TO APPROACH ON
TUESDAY. WE THEREFORE ADDED A MENTION OF FREEZING DRIZZLE TO THE
GRIDS LATE MONDAY NIGHT THROUGH TUESDAY...AS THE FRONTAL ZONE
MOISTENS UP...BUT BEFORE LIFT BECOMES DEEP ENOUGH TO SUPPORT SNOW.

REGARDING THE POTENTIAL WINTER STORM...WE STRONGLY CONSIDERED A
WINTER STORM WATCH ON THIS SHIFT...BUT THROUGH COLLABORATION WITH
SURROUNDING OFFICES...CHOSE TO DEFER TO THE NEXT SHIFT. MODELS ARE
CONSISTENT IN THE SWATH OF HEAVIEST SNOW BEING ACROSS THE MAIN BODY
OF OKLAHOMA...WITH LESSER AMOUNTS INTO TEXAS. THERE IS STILL SOME
QUESTION...THOUGH...AND RUN TO RUN INCONSISTENCY...AS TO THE TIMING
OF INITIAL ONSET AND THE DEGREE TO WHICH THE FRONTAL WAVE AMPLIFIES
TUESDAY NIGHT AND WEDNESDAY. THE SNOWFALL AMOUNTS IN THE SREF MEAN
ARE LIGHTER THAN THE OPERATIONAL MODELS...THOUGH STILL SUPPORTIVE OF
WINTER STORM CRITERIA...ESPECIALLY GIVEN THE GUSTY WINDS AND LOW WIND
CHILLS EXPECTED. WE TENDED TO LIKE THE SREF MEAN SNOWFALL...ROUGHLY
3-6 INCHES...AS THIS SYSTEM DOES NOT YET SHOW ANYTHING BUT AN OPEN
TROUGH AT 700 MB...AND IS PROGRESSIVE IN NORTHWESTERLY FLOW...RATHER
THAN TURNING THE CORNER AND UNDERGOING CYCLOGENESIS IN SOUTHWESTERLY
FLOW...WHICH WOULD UNDOUBTEDLY LEAD TO HEAVIER SNOWFALL. GIVEN THAT
THE PERIODS OF INTEREST ARE JUST BEYOND 48 HOURS...WE WILL LET THE
UPPER SYSTEM COME INTO THE UPPER AIR NETWORK THIS EVENING...LETTING
THE NIGHT SHIFT TAKE A LOOK AT MODEL TRENDS BEFORE PUTTING OUT WHAT
WE WOULD THINK SHOULD BE A FAIRLY LIBERAL WINTER STORM WATCH.

.UPDATE...
PRECIPITATION CONTINUES TO DIMINISH ACROSS THE SOUTHERN PART OF THE
FORECAST AREA THIS EVENING. TEMPERATURES HAVE REMAINED WARM ENOUGH
FOR LIQUID PRECIPITATION... ALTHOUGH A CHANGE TO LIGHT
SNOW/FLURRIES STILL LOOKS POSSIBLE AS THE TEMPERATURES COOL. HAVE
ADJUSTED THE WEATHER GRIDS TO KEEP MORE LIQUID PRECIPITATION LATE
THIS EVENING BUT STILL MAINTAINING A MIX. MID-LEVEL CLOUDS ACROSS
MUCH OF THE AREA HAVE KEPT TEMPERATURES RELATIVELY WARM. MIN
TEMPERATURES OVERNIGHT MAY STAY HIGHER THAN CURRENT FORECAST BUT
WITH SOME CLEARING MOVING INTO THE NORTHWEST PORTION OF THE AREA
MAY STILL MAKE THE FORECAST MINS LATE... ALTHOUGH HAVE ADJUSTED
HOURLY TEMPERATURE GRIDS TO SLOW THE COOLING DOWN OVERNIGHT.

WENT AHEAD AND ISSUED THE WINTER STORM WATCH FOR TUESDAY NIGHT AND
WEDNESDAY AT THE BEGINNING OF THE SHIFT AS THERE HAS BEEN A
SOMEWHAT PERSISTENT SIGNAL FOR AT LEAST THE POTENTIAL OF 4+
INCHES OF SNOW SOMEWHERE OVER THE FORECAST AREA. AS ALWAYS THERE
IS STILL SOME UNCERTAINTY IN THE EXACT STORM PATH... BUT
CONFIDENCE IS SUFFICIENT FOR A WATCH AT THIS STAGE. 00Z NAM
ISENTROPIC ANALYSIS IN THE 285K THROUGH 295K LAYERS SHOWS A GOOD
FETCH OF MOISTURE FROM THE SOUTH LIFTING OVER THE FRONTAL ZONE ON
TUESDAY NIGHT AND WEDNESDAY.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
404 AM CST MON FEB 7 2011

.DISCUSSION...
MAIN FOCUS THIS MORNING HAS BEEN ON FINE-TUNING THE QPF AND SNOW
ACCUMULATION GRIDS TUE-WED - TO THE EXTENT POSSIBLE AS WE ARE
STILL ROUGHLY 48 HRS FROM THE TIME OF MOST RAPIDLY-DETERIORATING
CONDITIONS. FURTHER CHANGES ARE LIKELY... BUT FOR NOW WE ARE STILL
COMING UP WITH WIDESPREAD 4-10 INCH TOTALS ACROSS THE NORTHERN 3/4
OF THE AREA. DISCREPANCIES CONTINUE BETWEEN MODELS WITH 06Z NAM
RUNNING A SWATH OF 10-15 INCHES ACROSS OUR N ZONES WHILE ECMWF AND
GFS HAVE 4+ TOTALS SPREADING FARTHER S INTO N TX. WE WILL LET THE
EXISTING WINTER STORM WATCH RIDE AT THIS TIME. AN EXTENSION
FARTHER S MAY BE NEEDED LATER... BUT CURRENT INDICATIONS ARE THAT
THE WORST OF IT WILL HOLD OFF UNTIL 5TH PERIOD/WEDNESDAY FOR AREAS
NOT ALREADY IN THE WATCH.

LOW-LEVEL WARM ADVECTION AND NORTHWARD MOISTURE TRANSPORT WILL BE
WELL UNDERWAY BY TUE MORNING COURTESY OF 50-KT LLJ. LIGHT PRECIP
MAY BREAK OUT AS EARLY AS MON NIGHT IN FAR N OK... ALTHOUGH MORE
LIKELY TO BE FARTHER N IN AREA OF INCREASING UPSLOPE FLOW AND LOW-
LEVEL MOISTURE CONVERGENCE OVER CENTRAL PLAINS. MAIN EVENT COULD
BEGIN LATE TUE IN NW OK... BUT TUE NIGHT WILL BE WHEN MOST AREAS
SEE SIGNIFICANT AND POSSIBLY RAPID DETERIORATION OF CONDITIONS.
STRONG INCREASE IN SFC THERMAL GRADIENT WITH THE ARCTIC FRONT TUE
NIGHT BEARS TESTIMONY TO THE STRENGTH OF THE LOW-LEVEL
FRONTOGENETIC FORCING TAKING PLACE. PRECIP INCREASING AND
SPREADING SE WITH/BEHIND SFC FRONT WHILE N WINDS INCREASE. POPS
ARE INCREASED TO CATEGORICAL ALL AREAS TUE NIGHT. THERE MAY BE A
RELATIVELY-BRIEF PERIOD OF WINTRY MIX NEAR THE FRONTAL ZONE TUE
NIGHT BEFORE A QUICK TRANSITION TO SNOW AND BLOWING SNOW. AFTER
ANOTHER MAJOR MESS WED MORNING OVER MUCH OF THE AREA... PRECIP
SHOULD SHUT DOWN FROM W TO E DURING THE DAY. MODEL QPFS ARE IN
GOOD AGREEMENT ON THIS TIMING. ARCTIC AIR WILL BE FLOODING INTO THE
AREA THE WHOLE TIME AND WILL SEND WIND CHILLS BACK DOWN BELOW ZERO
BY WED MORNING IN MOST AREAS. ONCE AGAIN WE WILL LIKELY END UP
WITH WIND CHILL ADVISORIES TO REPLACE ANY WARNINGS BY LATE WED.

NOTE THAT SFC WINDS WILL INCREASE DURING THE EVENT BUT DO NOT LOOK
AS STRONG AS THE ONE LAST WEEK. ALTHOUGH BLOWING AND DRIFTING WILL
BE CONSIDERABLE... AND IN FACT MAY BE WORSE THAN THE LAST ONE IF
SNOW AMOUNTS ARE HEAVIER... WE DO NOT ANTICIPATE BLIZZARD
CONDITIONS AT THIS TIME.

DRY AND COLD WED-THU WITH WED NIGHT LIKELY TO BE THE COLDEST IN
TERMS OF ACTUAL TEMPERATURES. WE WILL FINALLY PUT AN END TO THIS
PATTERN THEREAFTER AS THE E-PAC RIDGE BREAKS DOWN AND THE FLOW
BECOMES ZONAL ACROSS THE CONUS. THIS NORMALLY WOULD LEAD TO A
QUICK AND SUBSTANTIAL WARMUP... BUT THE RESIDUAL SNOW COVER MAY
DELAY THE RETURN OF ABOVE-NORMAL TEMPS UNTIL LATE IN THE WEEKEND
OR EARLY NEXT WEEK. NEEDED TO IMPROVISE ON HIGH/LOW TEMPS FOR THIS
FORECAST AS GUIDANCE IS LIKELY WARMING US UP TOO MUCH TOO FAST.
TMAX/TMIN GRIDS BEYOND WED ARE A CONSENSUS BLEND OF ADJACENT GRIDS.

AREA FORECAST DISCUSSION

317 PM CST MON FEB 7 2011

.DISCUSSION...MIDDAY UPGRADE TO WINTER STORM WARNING WAS BASED ON
REMARKABLE MODEL CONSISTENCY REGARDING WARNING CRITERIA...4 TO 8
INCH...SNOW AMOUNTS WITHIN THE BORDERS OF OKLAHOMA. GREATER
UNCERTAINTY EXISTS TOWARD THE BORDERS...ESPECIALLY SOUTH INTO
TEXAS...WHERE MID LEVEL ASCENT WILL BE OF SHORTER DURATION...AND
MODEL SNOWFALL DROPS TO NEAR OR JUST BELOW WARNING CRITERIA OF 4
INCHES. WITH TWO FORECAST CYCLES LEFT BEFORE THE ONSET OF SNOW IN
OUR TEXAS COUNTIES...WE OPTED TO DEFER AN ADVISORY-VERSUS-WARNING
DECISION TO LATER SHIFTS.

IN OKLAHOMA...HOWEVER...IT LOOKS AS THOUGH THIS FRONTAL STORM
SYSTEM...DESPITE REMAINING OPEN/ NOT DEVELOPING A CLOSED LOW/...
WILL BE A VERY EFFICIENT SNOW PRODUCER. THE TEMPERATURE PROFILES ARE
JUST SO FAVORABLE FOR MODERATE TO HEAVY SNOWFALL...GIVEN THAT THE
COLD AIR IS ALREADY IN PLACE...AND WILL GET COLDER...PLACING A DEEP
LAYER OF -10 TO -20 C AIR COINCIDENT WITH THE STRONGEST LIFT IN THE
CLOUD LAYER. STEEP LAPSE RATES ABOVE 600 MB SHOULD ALSO ENHANCE SNOW
GROWTH IN THE UPPER PART OF THE CLOUD...THUS SEEDING THE REST OF THE
CLOUD WITH NUCLEI FOR GROWTH BY ACCRETION.

THE ECMWF HAS BEEN A MODEL OF CHOICE PRIMARILY FOR ITS HANDLING OF
THE SURFACE COLD AIR AND INITIAL ONSET OF PRECIPITATION. THE 12Z GFS
CAME IN VERY CLOSE TO THE ECMWF. THE NAM IS THE MOST NOTABLE OUTLIER
IN THE SENSE THAT IT PROBABLY DOES NOT MOVE THE COLD AIR QUICKLY
ENOUGH TUESDAY IN THE WAKE OF A NORTHERN STREAM WAVE. THE NAM ALSO
INDUCES A STRONGER PRESSURE WAVE AT LOW LEVELS ALONG THE FRONT ON
WEDNESDAY...WHICH RESULTS IN CYCLOGENESIS AND EVEN GREATER SNOWFALL
THAN APPEARS IN OUR FORECAST. WHILE THE NAM AT LEAST REPRESENTS ONE
POSSIBILITY WITHIN THE SPECTRUM...IT DOES NOT HAVE SUPPORT FROM
OTHER GUIDANCE...AND DOES NOT APPEAR LIKELY...AS THE MID LEVEL
FORCING SHOULD REMAIN LOCATED WELL NORTH OF THE FRONT.

WHILE WE LEFT THE GRIDDED FORECAST LARGELY INTACT FROM THE PREVIOUS
SHIFT...THERE WERE A FEW CHANGES. WE INCREASED POPS TUESDAY AND
ADDED MENTION OF FREEZING DRIZZLE IN THE NORTH...WHICH MAY EVEN
BEGIN LATE TONIGHT. THE DRIZZLE WILL LIKELY OCCUR AS THE LOW LAYERS
SATURATE WITHIN STRONG UPGLIDE...AND BEFORE MID LEVEL ASCENT IS
SUFFICIENT TO GET SNOW GROWTH. MODELS...INCLUDING THE SREF...PLACE
ACCUMULATING SNOW IN NORTHERN OKLAHOMA BY TUESDAY AFTERNOON...SO THE
WINTER STORM WARNING BEGINS THERE AT 3 PM. AND WE EXTENDED THE END
OF THE EVEN INTO WEDNESDAY EVENING OVER SOUTHEAST OKLAHOMA.

VERY LOW WIND CHILLS WILL DEVELOP DURING THE STORM...AND A WIND
CHILL ADVISORY MAY BE NEEDED AFTER THE WINTER STORM WARNING EXPIRES.
WINDS WILL AVERAGE 20 TO 25 MPH. SOME GUSTS TO 40 ARE LIKELY. NEAR
BLIZZARD CONDITIONS MAY EXIST WEDNESDAY MORNING. THE WINDS WILL
DECREASE MORE QUICKLY IN THE WAKE OF THIS SYSTEM...EVEN BY
WEDNESDAY AFTERNOON...COMPARED TO THE PREVIOUS WINTER STORM.

AFTER THIS STORM...THE LONG WAVE PATTERN TRANSITIONS TO ONE
FEATURING LESS BLOCKING TO OUR EAST...AND A MORE PROGRESSIVE ZONAL
FLOW THAT WILL FEATURE SOME MILDER WEATHER AT LEAST.

454 AM CST TUE FEB 8 2011

.DISCUSSION...
TODAY WILL BE QUITE DIFFERENT FOR DIFFERENT PARTS OF OUR FORECAST
AREA. COLD EAST WINDS AND OCCASIONAL SNOW WILL BE TYPICAL IN THE
NORTH... WHILE OUR SOUTHERN COUNTIES WILL BE RELATIVELY MILD FOR
EARLY FEBRUARY.

THE COLD AIRMASS WILL EDGE SOUTH DURING THE DAY... BRINGING THE
SNOW WITH IT. AFTER SNOW BEGINS TO ACCUMULATE... THE MODERATE
NORTH TO NORTHEAST WINDS WILL START BLOWING IT AROUND. BY THIS
EVENING... RAIN AND SNOW WILL EXTEND AS FAR SOUTH AS I-40...
PERHAPS FARTHER.

THE PROVERBIAL WINTRY MIX IS LIKELY ACROSS OUR SOUTHERN COUNTIES
THIS EVENING... AND EVEN DURING THE NIGHT IN OUR FAR SOUTHEAST
COUNTIES. THIS WILL HOLD DOWN SNOWFALL ACCUMULATIONS SOMEWHAT IN
THOSE AREAS... BASICALLY THE SOUTHERN HALF OF OKLAHOMA... AND OUR
TEXAS COUNTIES.

AS THE STORM SYSTEM SHIFTS TOWARD THE EAST... ALL THE
PRECIPITATION WILL TURN TO SNOW... THEN END FROM WEST TO EAST
DURING THE DAY ON WEDNESDAY. COLD AIR WILL CONTINUE TO FLOW
SOUTH... AND TEMPERATURES WILL NOT RECOVER VERY MUCH DURING THE
DAY. VERY COLD OVERNIGHT LOWS ARE IN STORE FOR THE NEXT SEVERAL
NIGHTS.

AFTER THE STORM DEPARTS... THE FLOW WILL BECOME MORE WESTERLY...
SO WE WILL HAVE NOT ONLY MORE A MORE MODERATE AIRMASS BEING
BROUGHT EAST... BUT A DOWNSLOPE COMPONENT TO THE WINDS. ALL THIS
MEANS A STRONG WARM-UP... EXCEPT THAT THE SNOW ON THE GROUND WILL
COUNTER THE WARM-UP VERY SIGNIFICANTLY. BY SUNDAY... MOST OR ALL OF
THE SNOW SHOULD BE GONE... AND TEMPERATURES WILL BE CLOSER TO THE
SEASONAL NORMALS. A SLIGHT COOL-DOWN IS EXPECTED ON MONDAY... BUT
NOTHING LIKE TODAY/TONIGHT.

AFTER THE PRESENT WINTER STORM DEPARTS... NO FURTHER PRECIPITATION
IS EXPECTED THROUGH THE 7-DAY FORECAST PERIOD.

WITH THIS FORECAST ISSUANCE... WE WILL ISSUE A WINTER WEATHER
ADVISORY FOR KNOX AND BAYLOR COUNTIES IN TEXAS... AND UPGRADE THE
WINTER STORM WATCH IN OUR OTHER 6 TEXAS COUNTIES TO A WARNING.

STRENGTHENING LOW PRESSURE... NOW CENTERED OVER N NM... WILL SHIFT

AVIATION WEATHER ACROSS OK AND TX TODAY. AS THE POSITION OF THE
LOW CHANGES... WIND DIRECTIONS ACROSS OK/N TX WILL SHIFT GRADUALLY

MAJOR WINTER STORM IS EXPECTED TO AFFECT ALL OUR TAF SITES THIS

CLOSED... AT LEAST IN THE MORNING... DUE TO DRIFTING/DRIFTED SNOW.

.DISCUSSION...
UPDATED GRIDDED FORECAST TO REMOVE MENTION OF FREEZING RAIN MOST
LOCATIONS. CURRENT AND FORECAST SOUNDINGS COLD ENOUGH FOR A
QUICK TRANSITION FROM RAIN TO SNOW WHERE BOUNDARY LAYER
TEMPERATURES ARE WARM ENOUGH FOR INITIAL MIX. SOME SLEET WILL BE
POSSIBLE AT ONSET OF PRECIPITATION LATE THIS AFTERNOON AND THIS
EVENING AS FINE-SCALE MODEL OUTPUT IS SHOWING SIGNALS FOR THUNDER
SLEET NEAR AND JUST NORTH OF FRONT. THIS WOULD MAINLY BE AN ISSUE
FROM WESTERN NORTH TEXAS THROUGH SOUTHWEST AND CENTRAL OKLAHOMA
EARLY TO MID-EVENING BEFORE COMMENCEMENT OF HEAVY SNOW.

DID NOT ALTER SNOWFALL TOTALS WITH THIS UPDATE. WIDESPREAD 4 TO 6
INCHES STILL APPEAR LIKELY...WITH HIGHER TOTALS OF AS MUCH AS 8
TO 10+ INCHES STILL APPEARING POSSIBLE IN ANY BANDED STRUCTURES
THAT DEVELOP ACROSS CENTRAL AND NORTHERN PORTIONS OF OKLAHOMA
OVERNIGHT. WHAT IS A CERTAINTY ACROSS THE REGION WILL BE
DRASTICALLY COLDER CONDITIONS TONIGHT INTO THURSDAY.

.DISCUSSION...
MODERATE SNOW AND BLOWING SNOW HAS MOVED INTO NORTHWEST OKLAHOMA...
WITH MINOR ACCUMULATIONS BEGINNING TO BE REPORTED NEAR THE
PANHANDLES BORDER. SHOULD SEE THE SNOWFALL INTENSITIES RAMP UP
ACROSS NORTHWEST AND WESTERN OKLAHOMA OVER THE NEXT SEVERAL HOURS.
THE SWATH OF MODERATE TO HEAVY SNOWFALL WILL DEVELOP FURTHER EAST AS
THE MAIN STORM SYSTEM SHIFTS FROM COLORADO OVER OKLAHOMA. THERE MAY
BE A SHORT PERIOD OF SOME SLEET... AND MAYBE EVEN THUNDER SLEET
ALONG A NARROW STRIP NEAR THE INTERSTATE 44 CORRIDOR PRIOR TO THE
SWITCHOVER. EVEN WITH A PERIOD OF SLEET... MOST MODELS CONTINUE TO
BE PRETTY CONSISTENT WITH WIDESPREAD 6+ INCHES OVER A LARGE PORTION
OF OUR CWA... WITH SOME LOCATIONS OVER THE NORTHERN HALF OF OKLAHOMA
PICKING UP CLOSE TO 10 INCHES. THE SNOW TOTALS OVER NORTHWEST
OKLAHOMA WILL HAVE TO BE WATCHED... AS HI RESOLUTION MODELS SHOWING
A PERIOD OF INTENSE SNOWFALL RATES AND SOMEWHAT HIGHER TOTALS. WE
WILL GO AHEAD AND LEAVE CURRENT TOTALS AS IS FOR NOW... ADJUSTING AS
NECESSARY THROUGH THE EVENING.

THE OTHER ISSUE WITH THIS STORM IS THE VERY COLD TEMPERATURES THAT
WILL OVERSPREAD THE AREA. MILD TEMPERATURES THIS AFTERNOON FROM
INTERSTATE 40 SOUTH WILL BE KNOCKED DOWN 20 TO 30 DEGREES BY
TOMORROW MORNING. VERY LITTLE RECOVERY WILL OCCUR TOMORROW AS
WELL... WHICH WILL MAKE IT FEEL QUITE UNBEARABLE OUTSIDE.

AS CONSISTENT AS THE MODELS HAVE BEEN WITH THIS WINTER STORM... THEY
HAVE ALSO BEEN CONSISTENT IN ENDING THE HEAVIER PRECIPITATION ENDING
FAIRLY QUICKLY FROM WEST TO EAST TOMORROW MORNING. GUSTY NORTHERLY
WINDS WILL KEEP BLOWING AND DRIFTING SNOW THROUGH THE AFTERNOON.

AFTER THE STORM MOVES EAST... A DRY FORECAST WILL DOMINATE THE
EXTENDED... AS THE LARGE SCALE PATTERN SHIFT WILL BE IN FULL FORCE.
WILL CONTINUE TO UNDERCUT GUIDANCE THROUGH SATURDAY DUE TO LINGERING
SNOW COVER. AFTER THAT... TEMPERATURES SHOULD BE AT OR JUST ABOVE
MID FEBRUARY AVERAGES.

.UPDATE...
PRIMARY PRECIPITATION BAND HAS SET UP FROM NORTH CENTRAL OKLAHOMA
SOUTHWEST INTO THE TEXAS PANHANDLE WITH THE PRECIPITATION
INCREASING SIGNIFICANTLY IN THE TEXAS PANHANDLE OVER THE LAST
COUPLE OF HOURS. IN THE NORTHERN OKLAHOMA BAND... SNOWFALL
ESTIMATES FROM LAW ENFORCEMENT INCLUDE 3 TO 4 INCHES AT BUFFALO...
4 TO 5 INCHES AT BLACKWELL AND AROUND 2 INCHES IN ENID SO FAR.
ALTHOUGH THE HEAVY SNOW EVENT IS ONGOING ACROSS THE NORTHERN TWO
TIERS OF COUNTIES IN OKLAHOMA... THE HEAVY SNOW BAND OVER THE
TEXAS PANHANDLE WILL MOVE EAST AND BECOME THE PRIMARY FEATURE OVER
WEST CENTRAL AND CENTRAL OKLAHOMA LATE THIS EVENING AND OVERNIGHT.

FARTHER SOUTHEAST... LIGHT RADAR REFLECTIVITIES HAVE CORRESPONDED
WITH SOME REPORTS OF LIGHT SNOW AND SLEET ACROSS CENTRAL AND
SOUTHERN OKLAHOMA. ALTHOUGH THE RADAR MAY BE OVERSHOOTING SOME OF
THE PRECIPITATION WITH FORCING AT SUCH LOW LEVELS.

HAVE MADE SOME RELATIVELY MINOR UPDATES TO THE PACKAGE THIS
EVENING... MAINLY TO UPDATE THE TIMING OF THE PRECIPITATION
/ESPECIALLY IN THE SOUTHEAST/... INCREASE WIND GUSTS /ESPECIALLY
IN THE SOUTHWEST/... AND REDUCE MIN TEMPERATURES IN MANY AREAS.
GIVEN THE SNOWFALL RATES AND EXPECTED EVOLUTION... THE PREDICTED
SNOWFALL AMOUNTS STILL LOOK REASONABLE. .26.

KWWR AND KPNC/ WITH THE FIRST SNOW BAND. RADAR SHOWS SNOW
INCREASING ACROSS WEST CENTRAL OKLAHOMA NEAR KCSM AND KHBR AND

426 AM CST WED FEB 9 2011

.DISCUSSION...
WIDESPREAD SNOW... SOME OF IT QUITE HEAVY... IS OCCURRING OVER
NEARLY ALL OUR FORECAST AREA AT THIS TIME. MODERATE TO STRONG
NORTH WINDS ARE ALSO CAUSING BLOWING AND DRIFTING TO OCCUR.

WE EXPECT THE HEAVIEST BANDS OF SNOW... NOW OVER NORTHERN
OKLAHOMA... TO SHIFT EAST RATHER QUICKLY... AND SHOULD BE EXITING
OUR FORECAST AREA BY THE BEGINNING OF THE FIRST PERIOD OF THIS
FORECAST. AS A RESULT... THE HEAVIEST SNOWFALL EXPECTED THIS
MORNING... AFTER ABOUT 7 AM... WILL BE OVER OUR SOUTHEASTERN
COUNTIES. BLOWING/DRIFTING SNOW ARE EXPECTED TO CONTINUE... MAINLY
OVER THE SOUTHWEST QUADRANT OF OKLAHOMA... AND ADJACENT PARTS OF
WESTERN NORTH TEXAS... WHERE WINDS WILL CONTINUE TO BE STRONGEST.

THE SNOW SHOULD TAPER OFF QUICKLY AS THE DAY PROGRESSES... AND THE
LAST FLAKES SHOULD FALL OVER OUR FAR SOUTHEAST COUNTIES LATE THIS
AFTERNOON. NEW SNOW ACCUMULATIONS AFTER NOON WILL BE RELATIVELY
LIGHT... ALTHOUGH AN INCH OR TWO WILL STILL BE POSSIBLE OVER
SOUTH-CENTRAL AND SOUTHEAST OKLAHOMA.

TONIGHT WILL BE VERY COLD... WITH FRESH SNOW COVER... LIGHT
WINDS... AND GENERALLY CLEAR SKIES. LOW TEMPERATURES WILL DIP
BELOW ZERO OVER MUCH OF NORTHERN AND CENTRAL OKLAHOMA... AND
SINGLE DIGITS WILL BE THE RULE TO THE SOUTH.

THE EXTENSIVE... AND HEAVY... SNOW COVER WILL RESULT IN A VERY
FEEBLE TEMPERATURE RECOVERY TOMORROW... AND TOMORROW NIGHT WILL BE
COLD AGAIN... BUT NOT QUITE AS COLD.

THE LARGE-SCALE WEATHER PATTERN CHANGES SIGNIFICANTLY LATE THIS
WEEK AND NEXT WEEK. MUCH WARMER WEATHER WILL RETURN TO THE
SOUTHERN PLAINS. HOWEVER... ANY LINGERING SNOW COVER WILL GREATLY
LIMIT THE WARM-UP... AS SOLAR RADIATION WILL GO FIRST TO MELTING
SNOW... AND THEN EVAPORATING THE MOISTURE LEFT BEHIND.
NEVERTHELESS... ALONG THE FRINGES OF THE SNOW... RELATIVELY
UNMODIFIED WARM AIR WILL STILL BE ABLE TO RAISE TEMPERATURES
MARKEDLY.

A FEW WEAK UPPER-LEVEL WAVES ARE FORECAST TO PASS OVER OKLAHOMA
AND NORTH TEXAS DURING THE LAST SEVERAL DAYS OF THE FORECAST...
BUT AT THIS TIME... IT APPEARS THAT MOISTURE WILL BE TOO LIMITED
TO WARRANT ANY MENTION OF RAIN CHANCES.

WE WILL NOT MAKE ANY CHANGES TO THE CURRENT WARNINGS AND
ADVISORY... HOWEVER... WE WOULD EXPECT THAT THE WARNING WILL BE
TERMINATED FROM WEST TO EAST DURING THE DAY... AND MAY BE REPLACED
WITH A WIND CHILL ADVISORY.

SNOWFALL OBSERVATIONS IS AVAILABLE AS A LOCAL STORM REPORT/LSR/ AND
PUBLIC INFORMATION STATEMENT/PNS/ FROM OUR OFFICE...AS WELL AS IN

THE STORM SYSTEM HAD LARGELY EXITED...ALTHOUGH COLD AIR CONTINUED TO
SPILL SOUTHWARD INTO THE BASE OF A LARGE TROUGH NOW CARVED OUT OVER
THE U.S. STREETS AFTERNOON STRATOCUMULUS AND SNOW FLURRIES WILL
DIMINISH WITH NIGHTFALL. WIND SPEEDS WILL ALSO COME DOWN

THERE IS NO WELL DEFINED HIGH PRESSURE CENTER TO SLIDE THROUGH THE
REGION. WITH CLEAR SKIES AND TEMPERATURES FALLING TO THE SINGLE
DIGITS ABOVE AND BELOW ZERO TONIGHT...WHAT LIGHT WIND THERE
IS...WILL MAINTAIN WIND CHILL TEMPERATURES CLOSE ADVISORY CRITERIA
IN SOME AREAS...AND SOLIDLY IN ADVISORY RANGE ACROSS NORTHERN
OKLAHOMA. GIVEN THAT ARCTIC OUTBREAKS OF THIS MAGNITUDE...AND
WIDESPREAD FRESH SNOW COVER...ARE RELATIVELY RARE...WE WILL CONTINUE
A WIND CHILL ADVISORY THROUGH MORNING TO HIGHLIGHT THE STILL
HAZARDOUS OUTDOOR CONDITIONS.

THE 12Z GFS AND NAM ARE GOOD INTO THE WEEKEND...THEN THE ECMWF WAS
PREFERRED IN THE EXTENDED...BUT MODEL DIFFERENCES ARE MINOR. WE
ANTICIPATE A STEADY WARMING TREND. SOME OF OUR WEST AND SOUTHWEST
COUNTIES WILL RISE JUST ABOVE FREEZING THURSDAY...AND WIDESPREAD SUN

TEMPERATURES...THE MOS GUIDANCE APPEARED TOO WARM IN THE FACE OF
SNOW COVER...BUT DOWNSLOPE WIND...SUNSHINE...AND SUBSTANTIALLY
WARMER 850 MB TEMPS LED US TO RAISE TEMPS A BIT FROM THE PREVIOUS
