AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
518 AM CST WED NOV 25 2009

.AVIATION...
OTHER THAN A FEW CIRRUS CLOUDS ACROSS NORTHERN OKLAHOMA... EXPECT
CLEAR SKIES AND UNLIMITED VISIBILITIES THROUGH THE PERIOD AS HIGH
PRESSURE COVERS THE SOUTHERN PLAINS. A MINOR FRONT WILL PASS
THROUGH ALL TAF SITES DURING THE DAY TODAY... SLIGHTLY SHIFTING
THE WIND DIRECTION AND RAISING SPEEDS FOR THE REST OF THE DAYTIME
HOURS.  LIGHT AND VARIABLE WINDS ARE EXPECTED AFTER SUNSET.

.PREV DISCUSSION... /ISSUED 416 AM CST WED NOV 25 2009/ 

DISCUSSION...
A LARGE AREA OF SURFACE HIGH PRESSURE WILL REMAIN IN CONTROL OF
THE WEATHER ACROSS THE SOUTHERN PLAINS UNTIL THIS WEEKEND. AS A
RESULT... SUNNY DAYS AND CLEAR NIGHTS WILL BE THE RULE... WITH
MILD TEMPERATURES AND LIGHT WINDS. A WEAK FRONT WILL PASS THROUGH
THE SOUTHERN PLAINS TODAY... DOING LITTLE MORE THAN CAUSE A
TEMPORARY SHIFT IN WIND DIRECTION. WINDS WILL BEGIN TO INCREASE ON
FRIDAY... AS THE NEXT STORM SYSTEM BEGINS TO APPROACH FROM THE WEST.

THIS STORM SYSTEM WILL BRING A CHANCE OF RAIN TO MOST OF OKLAHOMA
AND NORTH TEXAS BY LATE IN THE WEEKEND... AND EARLY NEXT WEEK. THE
GREATEST CHANCES... AS USUAL... WILL BE ACROSS THE SOUTHEAST HALF
OF OUR FORECAST AREA. AS THE MAIN STORM SYSTEM MOVES AWAY FROM US
ON MONDAY AND TUESDAY... RAIN CHANCES WILL DIMINISH AGAIN. AT THIS
TIME... IT APPEARS THAT TEMPERATURES WILL BE A LITTLE TOO WARM FOR
FROZEN PRECIPITATION... BUT THERE IS STILL A POTENTIAL FOR SNOW
MIXING WITH THE RAIN IF MODELS SHIFT FEATURES A LITTLE FARTHER
SOUTH AGAIN.

AFTER ANOTHER PERIOD OF MILD WEATHER AROUND THE MIDDLE OF NEXT
WEEK... BOTH THE GFS AND ECMWF PULL A RATHER COLD CANADIAN AIRMASS
SOUTH INTO THE SOUTHERN PLAINS... PROBABLY COLDER THAN ANY WE HAVE
SEEN SO FAR THIS SEASON. BUT... THAT IS BEYOND THE RANGE OF THIS
FORECAST.
