AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
1124 PM CST WED MAR 7 2012

.AVIATION...
WIDESPREAD SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP
OVERNIGHT AS A COLD FRONT SLIDES SOUTHWARD ACROSS THE REGION.
PERSISTENT MVFR/IFR CIGS AND VSBYS ARE EXPECTED THROUGH THE DAY
AS COLD AIR FILLS IN BEHIND THE FRONT AND RAIN CHANCES REMAIN
HIGH. WINDS WILL SHIFT FROM SOUTHEAST AHEAD OF THE FRONT...TO
NORTHEAST AND GUSTY BEHIND IT. IN ADDITION TO SHOWERS AND
STORMS...SOME LIGHT SNOW OR SLEET MAY DEVELOP AT TAF SITES ACROSS
NORTHWEST OKLAHOMA LATE THIS AFTERNOON. RAIN CHANCES WILL PERSIST
THROUGH THE END OF THE TAF PERIOD.

&&

.PREV DISCUSSION... /ISSUED 906 PM CST WED MAR 7 2012/

UPDATE...
SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP ALONG AND
BEHIND THE COLD FRONT THIS EVENING. THE COLD FRONT IS PROGRESSING
SOUTH A LITTLE BIT FASTER THAN PREVIOUSLY FORECAST SO HAVE
ADJUSTED GRIDS TO SHOW SLIGHTLY FASTER MOVEMENT. ALSO ADJUSTED
POPS FOR CURRENT AND EXPECTED POSITION OF ACTIVITY. SOME OF THE
ELEVATED THUNDERSTORMS MAY PRODUCE HAIL TONIGHT BUT WIDESPREAD
SEVERE WEATHER IS NOT EXPECTED. WILL SEND UPDATES SHORTLY.

MAXWELL

PREV DISCUSSION... /ISSUED 542 PM CST WED MAR 7 2012/

AVIATION...
VFR CIGS ACROSS THE REGION WILL LOWER TONIGHT AHEAD OF A
SOUTHWARD MOVING COLD FRONT. WIDESPREAD AND PROLONGED MVFR/IFR
CIGS AND VSBYS ARE EXPECTED TONIGHT THROUGH TOMORROW AFTERNOON AS
THE COLD FRONT CONTINUES SOUTHWARD...BRINGING RAIN AND ISOLATED
THUNDERSTORMS ALONG AND BEHIND THE FRONT. GUSTY NORTH TO
NORTHEAST WINDS WILL DEVELOP BEHIND THE FRONT...ESPECIALLY
TOMORROW AFTERNOON.

PREV DISCUSSION... /ISSUED 236 PM CST WED MAR 7 2012/

DISCUSSION...
SOUTH WINDS CONTINUE TO PULL MOISTURE NORTHWARD INTO THE AREA AHEAD
OF STORM SYSTEM CURRENTLY OVER NORTHERN AZ. THIS SYSTEM WILL BECOME
CLOSED-OFF AND BEGIN ITS SLOW EASTWARD DRIFT TONIGHT INTO THE
UPCOMING WEEKEND. AS THIS OCCURS THERE WILL BE A CHANCE OF RAIN
BEGINNING TONIGHT... WHICH WILL BE MAINLY ASSOCIATED WITH A SFC COLD
FRONT THAT WILL MOVE SOUTHEAST ACROSS OKLAHOMA INTO NORTH TEXAS. A
FEW ELEVATED THUNDERSTORMS ALSO POSSIBLE BEHIND THE FRONT OVERNIGHT.
COULD DEVELOP SOME STRONGER STORMS DURING THE DAY ON THURSDAY ACROSS
PORTIONS OF SOUTHEAST OKLAHOMA... BUT SHOULD SHIFT SOUTHEAST OF AREA
QUICKLY AS SFC FRONT PUSHES THROUGH.

THIS IS A MORE SIGNIFICANT COLD FRONT THAN WE HAVE SEEN FOR A WHILE
AND EXPECT TO SEE FALLING TEMPS LATE TONIGHT AND CONT THROUGH THE
DAY TOMORROW BEHIND THE FRONT. THIS MAY ALLOW SOME MIX PRECIP TO
OCCUR BY LATE IN THE DAY ACROSS NORTHWEST OK. AFTER LOOKING AS
FORECAST SOUNDINGS IT APPEARS THAT SOME SLEET MAY BE POSSIBLE
NORTHWEST/PORTIONS OF WESTERN OK THEN TRANSITION TO SNOW THU NIGHT.
COULD BE SOME ACCUMULATIONS... MAINLY ON GRASSY SURFACES. COLD RAIN
CHANCES CONT FRI INTO SAT.

MODELS CONT TO DIFFER WITH UPPER LOWS EASTWARD PROGRESSION AND HOW
TO HANDLE PIECE OF ENERGY THAT WANTS TO TRANSLATE AROUND THE LOW
OVER THE WEEKEND. HOWEVER... LATEST RUNS OF BOTH THE NAM AND ECM
HAVE COME MORE IN LINE WITH THE GFS IN DEVELOPING TWO CLOSED LOWS BY
EARLY IN THE WEEKEND AND THEN SWINGING THE SECONDARY LOW THROUGH THE
AREA ON SUNDAY. IT STILL APPEARS THE BETTER RAIN CHANCES WILL CONT
TO BE ACROSS EASTERN OKLAHOMA OVER THE WEEKEND... BUT MAY BE A BIT
MORE DELAYED LINGERING THROUGH SUNDAY AND SUNDAY NIGHT.  A QUICK
WARM UP IS STILL ANTICIPATED INTO EARLY NEXT WEEK.
