.DISCUSSION...
AVIATION DISCUSSION FOR THE 00Z TAFS IS BELOW.

.AVIATION...
THE AVIATION FORECAST REMAINS TRICKY.

WENT WITH MORE OPTIMISTIC CONDITIONS THAN THE PREVIOUS TAFS.
GENERALLY BELIEVE VFR/MVFR CONDITIONS WILL PREVAIL WITH THE
HIGHEST CHANCES FOR VFR OVER NORTHERN OKLAHOMA. THERE IS A CHANCE
FOR IFR OR LOWER CONDITIONS AT NEARLY ANY SITE...ESPECIALLY NEAR
KLAW AND KSPS...BUT DID NOT MENTION DUE TO LOW CONFIDENCE OF
OCCURRENCE.

-DZ OR -FZDZ MAY DEVELOP SOUTH OF KHBR-KOUN AFTER 06Z...BUT DID
NOT MENTION DUE TO LOW CONFIDENCE OF OCCURRENCE.

.PREV DISCUSSION... /ISSUED 238 PM CST SUN MAR 1 2015/

DISCUSSION...
WITH THIS ISSUANCE...WE WILL NOT ISSUE ANY NEW WINTER WEATHER
ADVISORIES. HOWEVER...A SPECIAL WEATHER STATEMENT WILL BE ISSUED
TO HIGHLIGHT AREAS THAT COULD SEE VERY LIGHT FREEZING PRECIP. NOT
OUT OF THE QUESTION ONE MAY BE NEEDED LATE TONIGHT AND EARLY
MONDAY ACROSS PORTIONS OF WESTERN NORTH TEXAS AND SOUTHERN
OKLAHOMA WHERE FREEZING DRIZZLE OR VERY LIGHT FREEZING RAIN
SHOWERS MAY DEVELOP. THERE ARE ALREADY TRAVEL ISSUES ACROSS THE
REGION...AND THIS WILL BE COMPOUNDED LATE TONIGHT AS SLUSHY/WET
UNTREATED ROADWAYS AND WALKWAYS REFREEZE. ADDITIONAL IMPACTS FROM
ANY LIGHT PRECIP IS CURRENTLY EXPECTED TO BE SHORT IN DURATION AND
NOT EXPECTED TO ADD MUCH TO REFREEZING ISSUE. ALL SHORT TERM
GUIDANCE NOT VERY AGGRESSIVE WITH ANY DENSE FOG/FREEZING FOG
ISSUES BUT WE WILL GO AHEAD AND MENTION FOG IN THE FORECAST.

TURN OVER TO NON-FREEZING/FROZEN PRECIP LATE TOMORROW MORNING FOR
A WHILE...AT LEAST UNTIL NEXT SURGE OF ARCTIC AIR ARRIVES LATE
TUESDAY. TRENDS OF MODELS STILL SHOW POSSIBILITY OF MAINLY LIGHT
RAIN TRANSITIONING TO FREEZING RAIN AND SLEET BEFORE ENDING AS
SNOW ON WEDNESDAY. NO SIGNIFICANT AMOUNTS EXPECTED. PRIOR TO THIS
TRANSITION THERE WILL BE A CHANCE FOR A FEW STORMS MAINLY OVER FAR
SOUTHEAST PORTIONS OF OKLAHOMA. NO SEVERE WEATHER CURRENTLY
EXPECTED.

THEREAFTER...MODERATION OF TEMPERATURES AND DRY WEATHER EXPECTED
INTO NEXT WEEKEND.

.AVIATION...
01/18Z TAFS...IFR CONDITIONS WILL DECREASE IN COVERAGE ACROSS
CENTRAL AND SOUTHERN OKLAHOMA AND DOWN AROUND KSPS FIRST FEW HOURS
OF FORECAST. DRIZZLE EXPECTED TO BECOME LESS WIDESPREAD AND CIGS
SHOULD RISE INTO MVFR MOST LOCATIONS THIS AFTERNOON. VFR PRIMARILY
ACROSS FAR NORTH-CENTRAL. WITH SNOW COVER AND SLIGHT UPSLOPE FLOW
OVERNIGHT WILL CONTINUE WITH GUIDANCE AND BRING IFR CONDITIONS
BACK TO MOST TERMINALS AFTER 03Z.

&&

.PREV DISCUSSION... /ISSUED 945 AM CST SUN MAR 1 2015/

UPDATE...
MADE A FEW MINOR TWEAKS TO THE FORECAST FOR TODAY. WITH LIGHT
NORTHEASTERLY WINDS AND OVERCAST SKIES...DECREASED AFTERNOON
TEMPERATURES SEVERAL DEGREES. TEMPERATURES SHOULD GENERALLY REMAIN
AT OR BELOW FREEZING MOST OF THE DAY ACROSS NORTHERN AND WESTERN
OKLAHOMA. OTHERWISE...HIGHS WILL RANGE FROM THE LOWER 30S CENTRAL
TO MID 30S ACROSS SOUTHERN OKLAHOMA AND NORTH TEXAS. WITH FREEZING
TEMPS HANGING ON A BIT LONGER...KEPT MENTION OF DRIZZLE OR
FREEZING DRIZZLE IN THROUGH THE AFTERNOON. TRAVEL CONDITIONS WILL
REMAIN POOR ON UNTREATED AND SECONDARY ROADS...AS ONLY MODEST
MELTING WILL OCCUR...AND ROADS LIKELY ICE OVER ONCE AGAIN TONIGHT.

AUSTIN

PREV DISCUSSION... /ISSUED 527 AM CST SUN MAR 1 2015/

AVIATION...
IFR CEILINGS ARE EXPECTED MOST OF THE TIME UNTIL 021200. LIGHT
FREEZING DRIZZLE WILL BE INTERMITTENT IN THE SOUTHEAST HALF OF
OKLAHOMA UNTIL MID-DAY TODAY. WARM AND MOIST AIR ALOFT WILL AGAIN
BRING A CHANCE FOR FREEZING RAIN EARLY MONDAY IN SOUTHERN OKLAHOMA
AND ADJACENT PARTS OF NORTH TEXAS.

PREV DISCUSSION... /ISSUED 325 AM CST SUN MAR 1 2015/

DISCUSSION...
THE WINTER WEATHER ADVISORY HAS BEEN EXTENDED THROUGH MOST OF THE
MORNING FOR MUCH OF SOUTHWEST, CENTRAL AND SOUTH CENTRAL OKLAHOMA.
LIGHT FREEZING DRIZZLE CONTINUES IN MOST OF THESE AREAS AND THE
ADVECTION PATTERN ASSOCIATED WITH IT IS FORECAST TO MAINTAIN UNTIL
A FEW HOURS AFTER SUNRISE. THE PREVIOUSLY-ISSUED ADVISORY FOR NW
OK WILL EXPIRE AT 6 AM AFTER A LOW RISK FOR SOME SLEET PASSES TO
THE NORTHEAST. THE COLD SURFACE LAYER WILL HOLD THROUGH MONDAY AND
WINDS IN THE BOUNDARY LAYER WILL CONTINUE WEAK TRANSPORT OF
MOISTURE OVER THE TOP OF THE COLD AIRMASS. PERIODS OF DRIZZLE OR
SOMETIMES LIGHT RAIN ARE POSSIBLE UNTIL THIS PATTER ERODES ON
TUESDAY. SURFACE TEMPERATURES MONDAY MORNING WILL BE BELOW
FREEZING. ALTHOUGH CHANCES ARE LOW AND MAINLY IN THE SOUTH, ANY
DRIZZLE WOULD FREEZE AT NIGHT. TUESDAY BRINGS A BIG CHANGE WITH
MODELS INDICATING A RAPID REMOVAL OF THE COLD AIR FROM SOUTHWEST
OKLAHOMA TOWARD THE EAST AND NORTHEAST AHEAD OF A STRONG COLD
FRONT. THE ECMWF AND GFS AND SURROUNDING OFFICE CONSENSUS IS THAT
THE FRONT WILL MOVE INTO NORTHERN OKLAHOMA MID-DAY TUESDAY AND
BRING QUICKLY FALLING TEMPERATURES. THERE IS A BRIEF WINDOW FOR
THUNDERSTORMS TUESDAY AFTERNOON MAINLY SOUTH AND EAST OF OKLAHOMA
CITY. A CHANCE OF SNOW, AND POSSIBLY SLEET COME EARLY WEDNESDAY
WITH THE APPROACH OF A FAST-MOVING WAVE IN THE NORTHERN BRANCH OF
PREVAILING WINDS. PRESENTLY,THERE ARE LIKELY POPS FOR MIXED
PRECIPITATION IN SOUTHEAST OKLAHOMA LATER WEDNESDAY. DRIER WEATHER
AND INCREASING TEMPERATURES FOLLOW INTO THE WEEKEND.

CHANGES TO PRECIPITATION TYPE AND TEMPERATURES.

DISCUSSION...
LOWERED EXPECTED HIGHS TODAY SEVERAL DEGREES...MOSTLY 20S INSTEAD
OF TEMPS AROUND AND ABOVE FREEZING. SOUTHERN PORTIONS OF OKLAHOMA
AND WESTERN NORTH TEXAS TO WILL APPROACH OR PERHAPS EXCEED THE
FREEZING MARK BRIEFLY THIS AFTERNOON. TEMPERATURES EXPECTED TO
THEN REMAIN STEADY OR SLOWLY CLIMB THROUGH THE EVENING AND NIGHT.

AS FAR AS PRECIPITATION TYPE...WILL SPEED UP NORTHWARD PROGRESSION
OF TRANSITION TO SLEET AND FREEZING DRIZZLE AND MID LEVEL TEMPS
INCREASE AND DRY.

PREV DISCUSSION... /ISSUED 601 AM CST SAT FEB 28 2015/

AVIATION...
IFR CONDITIONS ARE WITH LOW CEILINGS ARE EXPECTED IN SNOW THIS
MORNING IN WESTERN AND CENTRAL OKLAHOMA. LIGHT SNOW WILL GIVE WAY
TO PERIODS OF LIGHT SLEET AND FREEZING RAIN THIS AFTERNOON AND
OVERNIGHT. FREEZING FOG IS EXPECTED TO DEVELOP EARLY SUNDAY.

PREV DISCUSSION... /ISSUED 416 AM CST SAT FEB 28 2015/

DISCUSSION...
ANOTHER AREA OF LIGHT SNOW IS MOVING THROUGH WESTERN AND NORTHERN
OKLAHOMA THIS MORNING, LIKELY TO GIVE 1 TO 3 INCHES. LESSER SNOW
AMOUNTS ARE EXPECTED FARTHER SOUTH WHERE SNOW WILL MIX THROUGH THE
TRANSITIONS TO SLEET AND FREEZING RAIN AS STRONG WARMING OCCURS
ABOVE THE BOUNDARY LAYER AND WORKS IT WAY TOWARD THE SURFACE
THROUGH THE DAY. AS THE MAIN WAVE HELPING MORNING SNOW PRODUCTION
IN THE NORTH MOVES OFF TO THE NORTHEAST, LESS SYNOPTIC LIFT WILL
EXIST IN SOUTHERN AREAS, BUT THE WARM ADVECTION WILL STILL CREATE
A GOOD CHANCE THROUGH THE AFTERNOON FOR THE PRECIPITATION
TRANSITION. A WINTER WEATHER ADVISORY REMAINS EFFECTIVE THROUGH
THE DAY IN MOST AREAS. CURRENTLY WE EXPECT A CHANCE FOR FREEZING
RAIN SATURDAY NIGHT TRANSITION TO ALL RAIN BY MID-DAY SUNDAY.
BECAUSE POPS ARE RELATIVELY LOW, THE ADVISORIES WILL EXPIRE AT 6
PM TODAY.

A WEAK FRONT LATER SUNDAY WILL BRING A WIND SHIFT, BUT NOT MUCH
COLDER AIR. STRONG WARMING ALOFT AND MIXING TO THE SURFACE WILL
BRING TEMPERATURES INTO THE 60S TUESDAY AFTERNOON. MOISTURE AND AN
UPPER LEVEL WAVE WILL BRING RAIN TO SOUTH CENTRAL AND SOUTHEAST
OKLAHOMA AND A CHANCE ELSEWHERE BEFORE A COLD FRONT MOVES ACROSS
LATER IN THE DAY. AFTER A COLD DAY WEDNESDAY, DOWNSLOPE FLOW AND
THE EVENTUAL PASSAGE OF THE LINGERING UPPER LONG-WAVE TROUGH
SHOULD BRING DRIER AND WARMER CONDITIONS AFTER WEDNESDAY.

TO PERIODS OF LIGHT SLEET AND FREEZING RAIN THIS AFTERNOON AND
OVERNIGHT. FREEZING FOG IS EXPECTED TO DEVELOP EARLY SUNDAY.

PREV DISCUSSION... /ISSUED 416 AM CST SAT FEB 28 2015/

DISCUSSION...
ANOTHER AREA OF LIGHT SNOW IS MOVING THROUGH WESTERN AND NORTHERN
OKLAHOMA THIS MORNING, LIKELY TO GIVE 1 TO 3 INCHES. LESSER SNOW
AMOUNTS ARE EXPECTED FARTHER SOUTH WHERE SNOW WILL MIX THROUGH THE
TRANSITIONS TO SLEET AND FREEZING RAIN AS STRONG WARMING OCCURS
ABOVE THE BOUNDARY LAYER AND WORKS IT WAY TOWARD THE SURFACE
THROUGH THE DAY. AS THE MAIN WAVE HELPING MORNING SNOW PRODUCTION
IN THE NORTH MOVES OFF TO THE NORTHEAST, LESS SYNOPTIC LIFT WILL
EXIST IN SOUTHERN AREAS, BUT THE WARM ADVECTION WILL STILL CREATE
A GOOD CHANCE THROUGH THE AFTERNOON FOR THE PRECIPITATION
TRANSITION. A WINTER WEATHER ADVISORY REMAINS EFFECTIVE THROUGH
THE DAY IN MOST AREAS. CURRENTLY WE EXPECT A CHANCE FOR FREEZING
RAIN SATURDAY NIGHT TRANSITION TO ALL RAIN BY MID-DAY SUNDAY.
BECAUSE POPS ARE RELATIVELY LOW, THE ADVISORIES WILL EXPIRE AT 6
PM TODAY.

A WEAK FRONT LATER SUNDAY WILL BRING A WIND SHIFT, BUT NOT MUCH
COLDER AIR. STRONG WARMING ALOFT AND MIXING TO THE SURFACE WILL
BRING TEMPERATURES INTO THE 60S TUESDAY AFTERNOON. MOISTURE AND AN
UPPER LEVEL WAVE WILL BRING RAIN TO SOUTH CENTRAL AND SOUTHEAST
OKLAHOMA AND A CHANCE ELSEWHERE BEFORE A COLD FRONT MOVES ACROSS
LATER IN THE DAY. AFTER A COLD DAY WEDNESDAY, DOWNSLOPE FLOW AND
THE EVENTUAL PASSAGE OF THE LINGERING UPPER LONG-WAVE TROUGH

DISCUSSION...
ANOTHER AREA OF LIGHT SNOW IS MOVING THROUGH WESTERN AND NORTHERN
OKLAHOMA THIS MORNING, LIKELY TO GIVE 1 TO 3 INCHES. LESSER SNOW
AMOUNTS ARE EXPECTED FARTHER SOUTH WHERE SNOW WILL MIX THROUGH THE
TRANSITIONS TO SLEET AND FREEZING RAIN AS STRONG WARMING OCCURS
ABOVE THE BOUNDARY LAYER AND WORKS IT WAY TOWARD THE SURFACE
THROUGH THE DAY. AS THE MAIN WAVE HELPING MORNING SNOW PRODUCTION
IN THE NORTH MOVES OFF TO THE NORTHEAST, LESS SYNOPTIC LIFT WILL
EXIST IN SOUTHERN AREAS, BUT THE WARM ADVECTION WILL STILL CREATE
A GOOD CHANCE THROUGH THE AFTERNOON FOR THE PRECIPITATION
TRANSITION. A WINTER WEATHER ADVISORY REMAINS EFFECTIVE THROUGH
THE DAY IN MOST AREAS. CURRENTLY WE EXPECT A CHANCE FOR FREEZING
RAIN SATURDAY NIGHT TRANSITION TO ALL RAIN BY MID-DAY SUNDAY.
BECAUSE POPS ARE RELATIVELY LOW, THE ADVISORIES WILL EXPIRE AT 6
PM TODAY.

A WEAK FRONT LATER SUNDAY WILL BRING A WIND SHIFT, BUT NOT MUCH
COLDER AIR. STRONG WARMING ALOFT AND MIXING TO THE SURFACE WILL
BRING TEMPERATURES INTO THE 60S TUESDAY AFTERNOON. MOISTURE AND AN
UPPER LEVEL WAVE WILL BRING RAIN TO SOUTH CENTRAL AND SOUTHEAST
OKLAHOMA AND A CHANCE ELSEWHERE BEFORE A COLD FRONT MOVES ACROSS
LATER IN THE DAY. AFTER A COLD DAY WEDNESDAY, DOWNSLOPE FLOW AND
THE EVENTUAL PASSAGE OF THE LINGERING UPPER LONG-WAVE TROUGH
SHOULD BRING DRIER AND WARMER CONDITIONS AFTER WEDNESDAY.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
1044 PM CST FRI FEB 27 2015

.DISCUSSION...
ANOTHER WIDESPREAD ROUND OF ACCUMULATING SNOW IS EXPECTED
AFTER 2 AM TONIGHT INTO SATURDAY.

LATEST RADARS INDICATED ONE BAND OF SNOW ASSOCIATED WITH
FRONTOGENESIS AROUND 800 MB FROM NEAR CHICKASHA TO NORMAN TO
SEMINOLE...WHICH IS FORECAST TO WEAKEN OVER THE NEXT FEW HOURS AS
IT MOVES NORTHEAST. ADDITIONAL LIGHT SNOW CONTINUES ACROSS
SOUTHERN OKLAHOMA AND WESTERN NORTH TEXAS. ACCUMULATIONS FROM
THESE FEATURES ARE EXPECTED TO BE LIGHT...GENERALLY A DUSTING TO
ONE INCH THROUGH THE NIGHT.

THE NEXT ROUND IS JUST GETTING STARTED OVER THE PANHANDLES
TO OUR WEST. THIS WILL MOVE EAST AND IMPACT THE AREA LATE TONIGHT
INTO SATURDAY. THE I-35 CORRIDOR WILL BEGIN TO BE IMPACTED IN THE
6 AM TO 8 AM RANGE. LIGHT TO MODERATE SNOW WILL BE THE MAIN
WEATHER TYPE...THOUGH SOME SLEET AND EVEN FREEZING RAIN MAY OCCUR
OVER SOUTHERN OKLAHOMA AND WESTERN NORTH TEXAS AS WARMER AIR
ALOFT MOVES IN. KEPT ACCUMULATIONS IN THE 1 TO 4 INCH RANGE WITH
THE HIGHEST ACCUMULATIONS IN NORTHERN OKLAHOMA WHERE BANDING OF
MODERATE SNOW IS HIGHEST...ALTHOUGH LATEST HRRR RUNS HAVE BEEN
SHIFTING THE HEAVIEST SNOW FARTHER SOUTH CLOSER TO I-40.

DURING THE DAY ON SATURDAY INTO SUNDAY MORNING...LIGHT ICE
ACCUMULATION FROM FREEZING DRIZZLE AND LIGHT RAIN FREEZING RAIN
WILL BE ANOTHER BIG CONCERN...AND WILL ONLY ENHANCE SLICK AND
HAZARDOUS TRAVEL. ALTHOUGH ICE AMOUNTS ARE EXPECTED TO BE LIGHT
AND GENERALLY UNDER 0.10 INCH...GLAZING MAY BE WIDESPREAD.

SLICK AND HAZARDOUS TRAVEL WILL CONTINUE THROUGH SUNDAY IN MANY
LOCATIONS. SOME IMPROVEMENT MAY OCCUR AS EARLY AS LATE SATURDAY
AFTERNOON IN FAR SOUTHERN OKLAHOMA AND WESTERN NORTH TEXAS WHERE
TEMPERATURES WILL RISE ABOVE FREEZING FIRST.

THE FIRST ROUND OF THIS MULTI-PART WEATHER EVENT IS STARTING TO
WIND DOWN. THROUGH MIDNIGHT...SIGNIFICANT SNOWFALL SHOULD BE
RESTRICTED TO THE SOUTHERN THIRD OR SO OF OKLAHOMA...AND WESTERN
NORTH TEXAS. THINGS BEGIN TO TURN VERY COMPLICATED TOMORROW...AS
HIGHER TEMPERATURES START TO ADVANCE NORTH. THIS WILL...OVER THE
COURSE OF THE WEEKEND...TURN THE SNOW TO SLEET...FREEZING
RAIN...AND THEN RAIN...WITH VARIOUS COMBINATIONS THEREOF DURING
THE TRANSITION PERIOD.

THE PREVIOUSLY-ISSUED ADVISORIES APPEAR TO MAKE SENSE FOR THE
REST OF TODAY/THIS EVENING. HOWEVER...THE EVENING SHIFT WILL NEED
TO TAKE ANOTHER LOOK AT SNOW/ICE ACCUMULATION POTENTIAL
OVERNIGHT...ESPECIALLY OVER SOUTHERN OKLAHOMA AND WESTERN NORTH
TEXAS. THIS MAY REQUIRE AN EXTENSION OF OUR CURRENT ADVISORY FOR
THAT AREA.

THE MAIN BRUNT OF THE NEXT UPPER-LEVEL WAVE SHOULD AFFECT THE
NORTHERN TWO ROWS OF COUNTIES IN OKLAHOMA TOMORROW. SNOWFALL
SHOULD BE SUFFICIENT TO WARRANT THE WINTER WEATHER ADVISORY THAT
WILL BE NEW WITH THIS FORECAST UPDATE.

FREEZING RAIN WILL PROBABLY REQUIRE ADDITIONAL ADVISORIES OVER THE
WEEKEND...BUT UNCERTAINTY IN TIMING AND LOCATION PRECLUDE ISSUING
THEM NOW.

BY TUESDAY...MOST OF THE WINTER WEATHER WILL TEMPORARILY MAKE WAY
FOR A SPRINGLIKE DAY...COMPLETE WITH A CHANCE OF THUNDERSTORMS
OVER THE SOUTHEASTERN HALF OR SO OF OKLAHOMA. AT THIS
TIME...SEVERE WEATHER APPEARS TO BE UNLIKELY.

IN KEEPING WITH THE THEME OF WILD EXTREMES OF WEATHER...ANOTHER
STRONG COLD FRONT IS SCHEDULED TO ARRIVE TUESDAY AFTERNOON IN
NORTHWEST OKLAHOMA...AND LATE TUESDAY EVENING IN THE SOUTHEAST.
SOME LIGHT SNOW OR OTHER FREEZING/FROZEN PRECIPITATION WILL BE
POSSIBLE WITH THIS SYSTEM...BUT IT DOES NOT LOOK LIKE A
SIGNIFICANT EVENT. AND...BY THE END OF THE WEEK...TEMPERATURES

ONGOING LIGHT TO MODERATE SNOW WILL RESULT IN IFR CONDITIONS

SITES. ADDITIONAL SNOW IS EXPECTED TO DEVELOP ACROSS WESTERN
OKLAHOMA AFTER 10Z. THIS AREA OF SNOW WILL MOVE EASTWARD THROUGH

QUICK UPDATE... DECENT BAND OF SNOW CONTINUES TO DEVELOP ALONG A
NARROW GRADIENT OF STOUT MID- LEVEL FORCING ALONG/NEAR THE RED
RIVER IN SWRN OK/WRN N TX. REPORTS THROUGH 930AM OF ISOLATED
AMOUNTS OF 1-2 INCHES WITHIN THIS BANDING. GIVEN STRENGTH OF THE
BAND ON KFDR... EXPECT AN ADDITIONAL ACCUMULATION OF 1 INCH...
WITH TOTALS OF 1 TO 4 INCHES NOT OUT OF THE QUESTION ACROSS
PORTIONS OF SWRN OK AND WRN N TX. PROFILES CONTINUE TO MOISTEN
ACROSS CENTRAL OK... BUT BEST FORCING LOOKS TO REMAIN ALONG SRN
OK/NRN TX. HOWEVER... EXPECT SOME LIGHT... MAYBE SOME MODERATE
BURSTS OF SNOW ACROSS CENTRAL OK DEVELOPING AFTER 18Z... BUT STILL
ONLY EXPECT A DUSTING TO 1 INCH FOR OKC METRO AND LOCATIONS ACROSS
NRN OK.

PREV DISCUSSION... /ISSUED 552 AM CST FRI FEB 27 2015/

AVIATION...
SNOW WILL INCREASE WEST TO EAST THIS MORNING ACROSS WESTERN AND
SOUTHERN OKLAHOMA AND ADJACENT PARTS OF NORTH TEXAS. THE WAVE
PRODUCING THIS AREA OF SNOW WILL MOVE INTO SOUTHEAST OKLAHOMA BY
MID-DAY. IFR CEILINGS ARE EXPECTED. LATE TONIGHT LIGHT SNOW WILL
MOVE ACROSS NORTHERN OKLAHOMA WITH REDUCED VISIBILITY AND LOWER
CEILINGS. WINDS WILL MAINTAIN NORTHEAST OR EAST.

PREV DISCUSSION... /ISSUED 403 AM CST FRI FEB 27 2015/

DISCUSSION...
THE FIRST OF TWO SHORT WAVE TROUGHS IS APPROACHING WESTERN
OKLAHOMA THIS MORNING. SNOW WILL SPREAD INTO WESTERN OKLAHOMA
SHORTLY. THE MAIN ENERGY OF THIS WAVE WILL MOVE ACROSS THE RED
RIVER AREA TODAY. AN ADVISORY FOR UP TO 4 INCHES OF SNOW REMAINS
EFFECTIVE FOR THIS AREA WITH PART OF NORTH TEXAS LIKELY TO HAVE
CLOSER TO THIS HIGHER AMOUNT. THE SNOW WILL SPREAD INTO SOUTHEAST
OKLAHOMA DURING THE AFTERNOON. AFTER A RELATIVE LULL IN
PRECIPITATION TONIGHT, A SECOND UPPER WAVE WILL MOVE ACROSS THE
PANHANDLES AND NORTHERN OKLAHOMA SATURDAY MORNING. THE ATMOSPHERE
WILL STILL REMAIN SUFFICIENTLY COLD AND MOIST FOR SNOW HERE. IT
APPEARS THAT HEAVIER SNOW WILL REMAIN IN KANSAS WITH UP TO A
COUPLE INCHES LIKELY IN NORTH CENTRAL OKLAHOMA BEFORE LATE
SATURDAY AFTERNOON. STRONG WARM ADVECTION ABOVE THE SURFACE LAYER
IS FORECAST BY SEVERAL MODELS FOR THE SECOND HALF OF SATURDAY OVER
THE SOUTHERN TWO-THIRDS OF OKLAHOMA. THIS WOULD ALLOW WEAKER WAVES
THAT MAY PASS OVER OKLAHOMA SATURDAY NIGHT AND SUNDAY MORNING TO
PRODUCE A BRIEF PERIOD OF FREEZING RAIN OR SLEET BEFORE SURFACE
TEMPERATURES EXCEED FREEZING LATER SUNDAY MORNING. AFTER A WARMER
SUNDAY AFTERNOON AND A WEAK FRONT MONDAY, STRONGER SOUTH WINDS AND
MILD CONDITIONS ARE EXPECTED TUESDAY. THIS WILL BE ASSOCIATED WITH
INCREASING UPPER SOUTHWEST FLOW AND GIVE A CHANCE FOR RAIN AND
THUNDERSTORMS WITH THE PASSAGE OF A WAVE EMBEDDED IN THE
SYNOPTIC-SCALE UPPER TROUGH. A COLD FRONT IS EXPECTED WEDNESDAY
AND POSSIBLY ANOTHER CHANCE FOR SNOW BEFORE THE LARGE-SCALE TROUGH
FINALLY MOVES EAST OF OKLAHOMA LATER WEDNESDAY OR THURSDAY.

SNOW WILL INCREASE WEST TO EAST THIS MORNING ACROSS WESTERN AND

PRODUCING THIS AREA OF SNOW WILL MOVE INTO SOUTHEAST OKLAHOMA BY

THE FIRST OF TWO SHORT WAVE TROUGHS IS APPROACHING WESTERN
OKLAHOMA THIS MORNING. SNOW WILL SPREAD INTO WESTERN OKLAHOMA
SHORTLY. THE MAIN ENERGY OF THIS WAVE WILL MOVE ACROSS THE RED
RIVER AREA TODAY. AN ADVISORY FOR UP TO 4 INCHES OF SNOW REMAINS
EFFECTIVE FOR THIS AREA WITH PART OF NORTH TEXAS LIKELY TO HAVE
CLOSER TO THIS HIGHER AMOUNT. THE SNOW WILL SPREAD INTO SOUTHEAST
OKLAHOMA DURING THE AFTERNOON. AFTER A RELATIVE LULL IN
PRECIPITATION TONIGHT, A SECOND UPPER WAVE WILL MOVE ACROSS THE
PANHANDLES AND NORTHERN OKLAHOMA SATURDAY MORNING. THE ATMOSPHERE
WILL STILL REMAIN SUFFICIENTLY COLD AND MOIST FOR SNOW HERE. IT
APPEARS THAT HEAVIER SNOW WILL REMAIN IN KANSAS WITH UP TO A
COUPLE INCHES LIKELY IN NORTH CENTRAL OKLAHOMA BEFORE LATE
SATURDAY AFTERNOON. STRONG WARM ADVECTION ABOVE THE SURFACE LAYER
IS FORECAST BY SEVERAL MODELS FOR THE SECOND HALF OF SATURDAY OVER
THE SOUTHERN TWO-THIRDS OF OKLAHOMA. THIS WOULD ALLOW WEAKER WAVES
THAT MAY PASS OVER OKLAHOMA SATURDAY NIGHT AND SUNDAY MORNING TO
PRODUCE A BRIEF PERIOD OF FREEZING RAIN OR SLEET BEFORE SURFACE
TEMPERATURES EXCEED FREEZING LATER SUNDAY MORNING. AFTER A WARMER
SUNDAY AFTERNOON AND A WEAK FRONT MONDAY, STRONGER SOUTH WINDS AND
MILD CONDITIONS ARE EXPECTED TUESDAY. THIS WILL BE ASSOCIATED WITH
INCREASING UPPER SOUTHWEST FLOW AND GIVE A CHANCE FOR RAIN AND
THUNDERSTORMS WITH THE PASSAGE OF A WAVE EMBEDDED IN THE
SYNOPTIC-SCALE UPPER TROUGH. A COLD FRONT IS EXPECTED WEDNESDAY
AND POSSIBLY ANOTHER CHANCE FOR SNOW BEFORE THE LARGE-SCALE TROUGH
FINALLY MOVES EAST OF OKLAHOMA LATER WEDNESDAY OR THURSDAY.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
552 AM CST FRI FEB 27 2015

.AVIATION...
SNOW WILL INCREASE WEST TO EAST THIS MORNING ACROSS WESTERN AND
SOUTHERN OKLAHOMA AND ADJACENT PARTS OF NORTH TEXAS. THE WAVE
PRODUCING THIS AREA OF SNOW WILL MOVE INTO SOUTHEAST OKLAHOMA BY
MID-DAY. IFR CEILINGS ARE EXPECTED. LATE TONIGHT LIGHT SNOW WILL
MOVE ACROSS NORTHERN OKLAHOMA WITH REDUCED VISITLITY AND LOWER
CEILINGS. WINDS WILL MAINTAIN NORTHEAST OR EAST.

.PREV DISCUSSION... /ISSUED 403 AM CST FRI FEB 27 2015/

DISCUSSION...
THE FIRST OF TWO SHORT WAVE TROUGHS IS APPROACHING WESTERN
OKLAHOMA THIS MORNING. SNOW WILL SPREAD INTO WESTERN OKLAHOMA
SHORTLY. THE MAIN ENERGY OF THIS WAVE WILL MOVE ACROSS THE RED
RIVER AREA TODAY. AN ADVISORY FOR UP TO 4 INCHES OF SNOW REMAINS
EFFECTIVE FOR THIS AREA WITH PART OF NORTH TEXAS LIKELY TO HAVE
CLOSER TO THIS HIGHER AMOUNT. THE SNOW WILL SPREAD INTO SOUTHEAST
OKLAHOMA DURING THE AFTERNOON. AFTER A RELATIVE LULL IN
PRECIPITATION TONIGHT, A SECOND UPPER WAVE WILL MOVE ACROSS THE
PANHANDLES AND NORTHERN OKLAHOMA SATURDAY MORNING. THE ATMOSPHERE
WILL STILL REMAIN SUFFICIENTLY COLD AND MOIST FOR SNOW HERE. IT
APPEARS THAT HEAVIER SNOW WILL REMAIN IN KANSAS WITH UP TO A
COUPLE INCHES LIKELY IN NORTH CENTRAL OKLAHOMA BEFORE LATE
SATURDAY AFTERNOON. STRONG WARM ADVECTION ABOVE THE SURFACE LAYER
IS FORECAST BY SEVERAL MODELS FOR THE SECOND HALF OF SATURDAY OVER
THE SOUTHERN TWO-THIRDS OF OKLAHOMA. THIS WOULD ALLOW WEAKER WAVES
THAT MAY PASS OVER OKLAHOMA SATURDAY NIGHT AND SUNDAY MORNING TO
PRODUCE A BRIEF PERIOD OF FREEZING RAIN OR SLEET BEFORE SURFACE
TEMPERATURES EXCEED FREEZING LATER SUNDAY MORNING. AFTER A WARMER
SUNDAY AFTERNOON AND A WEAK FRONT MONDAY, STRONGER SOUTH WINDS AND
MILD CONDITIONS ARE EXPECTED TUESDAY. THIS WILL BE ASSOCIATED WITH
INCREASING UPPER SOUTHWEST FLOW AND GIVE A CHANCE FOR RAIN AND
THUNDERSTORMS WITH THE PASSAGE OF A WAVE EMBEDDED IN THE
SYNOPTIC-SCALE UPPER TROUGH. A COLD FRONT IS EXPECTED WEDNESDAY
AND POSSIBLY ANOTHER CHANCE FOR SNOW BEFORE THE LARGE-SCALE TROUGH
FINALLY MOVES EAST OF OKLAHOMA LATER WEDNESDAY OR THURSDAY.

THE 00Z AVIATION DISCUSSION FOLLOWS...

AVIATION...
VFR CONDITIONS ARE EXPECTED THROUGH THE OVERNIGHT HOURS. CHANCE OF
SNOW WILL INCREASE ACROSS WESTERN OKLAHOMA AFTER 12Z. THIS WILL
MOVE EASTWARD THROUGH THE MORNING. CONFIDENCE FOR SNOW IS HIGH
ENOUGH TO INCLUDE -SN AT ALL TAF SITES EXCEPT KPNC. EXPECT MVFR TO
IFR CONDITIONS IN AREAS OF SNOW. SNOW WILL END WEST TO EAST LATE
AFTERNOON. WINDS WILL VEER FROM MORE OF A NORTHERLY COMPONENT TO
EASTERLY COMPONENT THROUGH THE TAF PERIOD.

MAHALE

PREV DISCUSSION... /ISSUED 349 PM CST THU FEB 26 2015/

DISCUSSION...
AN ACTIVE WEATHER PATTERN KICKS OFF LATE TONIGHT... WITH SNOW MOVING
IN FRIDAY MORNING AND WINTRY AND WET WEATHER CONTINUING THROUGH THE
WEEKEND INTO EARLY NEXT WEEK.

THE WEAK SHORT WAVE TROUGH WILL CONTINUE TO TRACK S/SE ACROSS THE
FOUR CORNERS INTO NRN NM/PANHANDLES OVERNIGHT. A WEAK WAVE... IT IS
NOT CARRYING TOO MUCH SOURCE MOISTURE WITH IT AND WITH SFC/BL WINDS
ACROSS THE REGION OUT OF THE N/NE... AND THE MID-LEVEL S/SW WINDS...
MOISTENING OF PROFILES ACROSS THE REGION WILL BE DEPENDENT ON THE
INCREASING MID-LEVEL ASCENT THROUGH FRI AM. WITH THIS IN MIND...
INITIAL ONSET OF SNOW FRI AM WILL BE DELAYED UNTIL AROUND 6AM FOR
FAR WRN OK/WRN N TX. SNOW CHANCES WILL INCREASE THROUGH THE MORNING
AS STOUT ISENTROPIC ASCENT CONTINUES ACROSS SRN/SWRN OK AND WRN N
TX. EXPECT ONE OR TWO SNOW BANDS TO DEVELOP ACROSS THE RED RIVER
VALLEY/TEXOMA BUT HOW WIDE... WHERE... AND WHAT TIME...REMAIN THE
BIG QUESTION MARKS. EXPECT SNOW CHANCES WILL SLOWLY ADVANCE EASTWARD
THROUGH NOON... WITH LIGHT SNOW DEVELOPING ACROSS CENTRAL AND
NORTHERN OKLAHOMA THROUGH THE AFTN. OVERALL... FORCING ALOFT STILL
APPEARS WEAKER THROUGH THE AFTN... SO IT WILL BE DIFFICULT TO
MODERATE SNOWFALL. AS FOR AMOUNTS... 1 TO 3 INCHES ACROSS FAR
WESTERN AND SRN OK AND WESTERN NORTH TEXAS IS NOT OUT OF THE
QUESTION... WITH THE BEST CHANCE ALONG THE WRN OK/NRN TX RED RIVER
VALLEY REGION. EXPECT A DUSTING TO AROUND AN INCH FOR LOCATIONS
ACROSS CENTRAL AND NRN OKLAHOMA.

FRIDAY NIGHT... LIGHT SNOW AND FLURRY CHANCES WILL CONTINUE AS THE
INITIAL WAVE LIFTS E/NE. AT THE SAME TIME... SFC/BL FLOW WILL BEGIN
TO VEER TO THE S/SE... ALONG WITH AN INCREASING WARM NOSE BETWEEN
APPROXIMATELY 900 TO 800MB. THIS WILL RESULT IN A WINTRY MIX
DEVELOPING ACROSS TEXOMA/SRN OK EARLY... SLEET/FZRA... WITH LIGHT
SNOW LINGERING ACROSS CENTRAL INTO NRN OK. THE TRANSITION LINE WILL
BEGIN TO MOVE NORTH THROUGH THE DAY AS THE WARM NOSE INCREASES
ACROSS THE REGION. A TRANSITION TO RAIN IS EXPECTED THROUGH THE
LATE AFTN ACROSS WRN N TX AND FAR SRN OK.

TEMPS WILL CONTINUE TO RAISE OVERNIGHT INTO SUNDAY... WITH RAIN
DEVELOPING ACROSS THE SRN HALF OF OK/WRN N TX AND A RA/FZRA MIX
ACROSS THE NRN HALF OF OK. BY SUNDAY AFTN ANY PRECIP SHOULD BE ALL
RAIN WITH HIGHS IN THE 40S. THIS TREND WILL CONTINUE INTO MONDAY AS
FZRA CHANCES RETURN ACROSS NRN OK THROUGH THE MORNING AND RAIN IN
THE AFTN. NO MAJOR IMPACTS ARE EXPECTED... WITH LITTLE TO NO ICE
ACCUMULATIONS.

ACTIVE PATTERN CONTINUES INTO TUESDAY... AS THE WRN TROUGH FINALLY
BEGINS TO ADVANCE INTO THE CENTRAL CONUS. RAIN CHANCES WILL INCREASE
ON TUESDAY WITH A FEW RUMBLES OF THUNDER AS WELL ACROSS CENTRAL AND
SRN OK IN THE AFTN AND TEMPS IN THE 60S. BY NEXT THU... IT LOOKS
LIKE ANOTHER FRONT COMES IN... WITH A POSSIBLY RETURN TO WINTER LIKE
WEATHER.
