IFR CEILINGS ARE EXPECTED MOST OF THE TIME UNTIL 021200. LIGHT
FREEZING DRIZZLE WILL BE INTERMITTENT IN THE SOUTHEAST HALF OF

THE WINTER WEATHER ADVISORY HAS BEEN EXTENDED THROUGH MOST OF THE

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

IT NOW LOOKS LIKE THE SNOW IS CONFINED TO EXTREME NORTHEAST OKLAHOMA
AND FAR NORTHWEST ARKANSAS AT THIS HOUR. FREEZING RAIN IS BECOMING MORE
OF AN ISSUE WITH AREAS OF FREEZING RAIN AND SLEET ACROSS SOUTHEAST
OKLAHOMA AND NORTHWEST ARKANSAS. A SOUTHWESTERLY LOW LEVEL JET OF
AROUND 60 MPH CONTINUES TO CREATE ISENTROPIC LIFT ACROSS THE REGION
THIS EVENING PRODUCING THE AREAS OF FREEZING RAIN AND SLEET. THIS IS
EXPECTED TO PERSIST FOR A GOOD DEAL OF THE NIGHT. HAVE INCREASED ICE
AMOUNTS SOME ACROSS EAST-CENTRAL OKLAHOMA INTO WESTERN ARKANSAS. STILL
BELOW WARNING CRITERIA. THE HRRR SHOWS THE PRECIP TAPERING OFF AROUND 3 AM.
WILL SEE MAINLY FREEZING DRIZZLE ACROSS THE REMAINDER OF NORTHEAST OKLAHOMA.

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.

...UPDATE...

.DISCUSSION...
A LOW PRESSURE SYSTEM CONTINUES TO DIVE SOUTHWARD ALONG THE WEST
COAST THIS MORNING WHILE A WAVE OVER CENTRAL CANADA BEGINS TO DROP
SOUTHWARD. THIS HAS ALLOWED FOR MORE OF THE SOUTHERN STREAM UPPER
LEVEL FLOW TO PUSH OVER THE REGION WITH LOW/MID LEVEL SOUTHWESTERLY
FLOW AND INCREASING WARM AIR ADVECTION OVER EASTERN OKLAHOMA AND
NORTHWEST ARKANSAS. THUS...IN RESPONSE...LIGHT TO MODERATE SNOW
CONTINUES TO SPREAD ACROSS MUCH OF EASTERN OKLAHOMA AND NORTHWEST
ARKANSAS LATE THIS MORNING.

LATEST NAM SOLUTION CONTINUES TO DEVELOP A MID LEVEL FRONTOGENIC
BAND PUSHING ACROSS FAR NORTHEAST OKLAHOMA INTO THE AFTERNOON
HOURS..WHILE THE 12Z GFS RUN HAS BACKED OFF SOME ON THIS COMPARED
TO THE 06Z RUN. CURRENT THINKING IS THAT ADDITIONAL SNOWFALL
AMOUNTS OF 3-4 INCHES...WITH LOCALLY HIGHER AMOUNTS COULD BE
POSSIBLE IF THIS BAND STAYS TOGETHER AND MOVES OVER FAR NORTHEAST
OKLAHOMA. ACROSS THE REST OF NORTHEAST OKLAHOMA AND NORTHWEST
ARKANSAS AN ADDITIONAL 1 TO 3 INCHES COULD BE POSSIBLE INTO THIS
EVENING. THUS...HAVE UPGRADED THE ADVISORY TO A WARNING FOR FAR
NORTHEAST OKLAHOMA AND WILL CONTINUE WITH AN ADVISORY FOR THE REST
OF THE CWA.

ACROSS SOUTHEAST OKLAHOMA INTO WEST CENTRAL ARKANSAS...THICKNESS
VALUES ARE EXPECTED TO INCREASE ALONG WITH A MID LEVEL WARM NOSE
THIS AFTERNOON AND EVENING WHICH WILL ALLOW FOR PRECIP TO BECOME
MORE OF A SNOW/SLEET MIX TO A POSSIBLE RAIN/FREEZING RAIN MIX.
THIS MIXED PRECIP CONTINUES TO LOOK LIKE IT SHOULD PUSH NORTHWARD
THROUGH THE EVENING AND OVERNIGHT TONIGHT...WITH LOCATIONS ALONG
THE OKLAHOMA KANSAS BORDER BEING THE LAST TO SWITCH OVER TO MIX
PRECIP.

TEMPS THIS AFTERNOON LOOK TO WARM LITTLE ACROSS MUCH OF NORTHEAST
OKLAHOMA AND NORTHWEST ARKANSAS...WITH WARMING CLOSER TO/JUST
ABOVE THE FREEZING MARK FOR SOUTHEAST OKLAHOMA. MORNING UPDATE
WILL BE TO ADJUST POP/WX GRIDS AND ALSO SNOW AMOUNT GRIDS BASED ON
THE MENTIONED ABOVE AND LATEST TRENDS.

.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.

.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.

DISCUSSION...
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
SHOULD REBOUND TO A FEW DEGREES BELOW THE SEASONAL AVERAGE.

MOST OF THE SNOW HAS TAPERED OFF THIS EVENING BUT NOT BEFORE A
NARROW MESOSCALE BAND OF VERY HEAVY SNOW DUMPED 5-7 INCHES
NORTH AND NORTHWEST OF TULSA. THE SECOND ROUND OF PRECIPITATION IS
ALREADY UNDERWAY HOWEVER AS AREAS OF SNOW ARE DEVELOPING ACORSS
PARTS OF CENTRAL AND SOUTHERN OKLAHOMA AS WARM ADVECTION
INCREASES. THE HRRR INDICATES THESE SNOW AREAS WILL EXPAND SLOWLY
NORTH OVERNIGHT AND INTENSIFY AROUND SUNRISE. AS A RESULT...HAVE
EXPANDED AND EXTENDED THE WINTER WEATHER ADVISORY TO INCLUDE OUR
ENTIRE FORECAST AREA FROM NOW UNTIL MIDNIGHT SATURDAY NIGHT. THE
ADVISORY WILL LIKELY NEED TO BE EXTENDED INTO SUNDAY MORNING IN
SOME PLACES.

THE HEAVIEST SNOWFALL IS STILL EXPECTED TO FALL ACROSS NORTHEAST
OKLAHOMA AND FAR NORTHWEST ARKANSAS SATURDAY MORNING INTO EARLY
AFTERNOON. A CHANGEOVER TO SOME LIGHT SLEET AND EVENTUALLY LIGHT
FREEZING RAIN AND/OR FREEZING DRIZZLE WILL OCCUR FROM SOUTH TO
NORTH SATURDAY AFTERNOON AND EVENING. ALTHOUGH THE FREEZING
RAIN/DRIZZLE IS EXPECTED TO BE LIGHT...TRAVEL PROBLEMS ARE LIKELY
EVEN DOWN TO THE RED RIVER GIVEN THE VERY COLD ANTECEDENT
TEMPERATURES.

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

.DISCUSSION...
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.

LOOK TO BE ACROSS SOUTHEAST OKLAHOMA WHERE AROUND ONE INCH...WITH
POSSIBLY LOCALIZED HIGHER AMOUNTS...WILL BE POSSIBLE NEAR THE RED
RIVER. AT THE ONSET OF PRECIP...THE SNOW WILL HAVE TO FIGHT
THROUGH DRIER AIR AT THE SURFACE WHICH COULD HELP TO LIMIT OVERALL
ACCUMULATIONS. FURTHER TO THE NORTH ACROSS NORTHEAST OKLAHOMA INTO
NORTHWEST ARKANSAS THE DRIER AIR SHOULD HELP TO KEEP SNOWFALL
AMOUNTS TO LESS THAN A HALF INCH...WITH MOST LOCATIONS BEING
LITTLE TO NO ACCUMULATION TO A COUPLE TENTHS. CURRENT WINTER
WEATHER HEADLINES CONTINUE TO LOOK REASONABLE AND WILL LET THE
ADVISORY RUN AS IS. MOST OF THE PRECIP LOOKS TO TAPER OFF THIS
EVENING...THOUGH AT LEAST A SLIGHT CHANCE OF ADDITIONAL LIGHT SNOW
LOOKS TO BE POSSIBLE OVERNIGHT TONIGHT. CHANCES THEN RAMP UP AGAIN
SATURDAY INTO SUNDAY AS ANOTHER SHORTWAVE AND COLD FRONT APPROACH
THE REGION.

THE COLD AIRMASS COMBINED WITH CLOUDY CONDITIONS SHOULD ALSO KEEP
TEMPS FROM WARMING ALL THAT MUCH WITH HIGHS IN THE LOW 20S TO

THE FIRST OF TWO SHORT WAVE TROUGHS IS APPROACHING WESTERN

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

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

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

ACROSS THE REGION. AHEAD OF THE APPROACHING WAVE...ACROSS EASTERN
OKLAHOMA AND NORTHWEST ARKANSAS...MOSTLY CLOUDY CONDITIONS WERE
COMMON WITH TEMPS IN THE MID TEENS TO MID 20S FROM NORTH TO SOUTH.

THE WAVE WILL CONTINUE TO SHIFT EASTWARD WITH CHANCES FOR SNOWFALL
INCREASING THIS AFTERNOON INTO THIS EVENING. GREATER CHANCES STILL
LOOK TO BE ACROSS SOUTHEAST OKLAHOMA WHERE AROUND ONE INCH...WITH
POSSIBLY LOCALIZED HIGHER AMOUNTS...WILL BE POSSIBLE NEAR THE RED
RIVER. AT THE ONSET OF PRECIP...THE SNOW WILL HAVE TO FIGHT
THROUGH DRIER AIR AT THE SURFACE WHICH COULD HELP TO LIMIT OVERALL
ACCUMULATIONS. FURTHER TO THE NORTH ACROSS NORTHEAST OKLAHOMA INTO
NORTHWEST ARKANSAS THE DRIER AIR SHOULD HELP TO KEEP SNOWFALL
AMOUNTS TO LESS THAN A HALF INCH...WITH MOST LOCATIONS BEING
LITTLE TO NO ACCUMULATION TO A COUPLE TENTHS. CURRENT WINTER
WEATHER HEADLINES CONTINUE TO LOOK REASONABLE AND WILL LET THE
ADVISORY RUN AS IS. MOST OF THE PRECIP LOOKS TO TAPER OFF THIS
EVENING...THOUGH AT LEAST A SLIGHT CHANCE OF ADDITIONAL LIGHT SNOW
LOOKS TO BE POSSIBLE OVERNIGHT TONIGHT. CHANCES THEN RAMP UP AGAIN
SATURDAY INTO SUNDAY AS ANOTHER SHORTWAVE AND COLD FRONT APPROACH
THE REGION.

THE COLD AIRMASS COMBINED WITH CLOUDY CONDITIONS SHOULD ALSO KEEP
TEMPS FROM WARMING ALL THAT MUCH WITH HIGHS IN THE LOW 20S TO

PRODUCING THIS AREA OF SNOW WILL MOVE INTO SOUTHEAST OKLAHOMA BY

THE FIRST OF TWO SHORT WAVE TROUGHS IS APPROACHING WESTERN

UPDATED PRECIP/WX...

.DISCUSSION...
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.
