AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
406 AM CST TUE FEB 28 2012
.DISCUSSION...
MOISTURE AND MODEST THERMAL ADVECTION THIS MORNING INTO
THE AFTERNOON SHOULD RESULT IN WIDELY SCATTERED LIGHT
RAIN SHOWERS WITH PERHAPS BETTER COVERAGE OUT WEST EARLY
THIS MORNING. 00Z NSSL WRF AND HRRR SIMILAR WITH BETTER CHANCES
FOR PRECIP EARLY THIS AFTERNOON LIFTING NORTH AND EAST OF FA.
BY MID TO LATE AFTERNOON...A DRYLINE WILL MIX INTO FAR WESTERN
OKLAHOMA AND THE ADJACENT AREA OF WESTERN NORTH TEXAS. DEEP MIXING
BEHIND THE DRYLINE SHOULD CREATE MODERATE TO HIGH END RED FLAG
CONDITIONS...ESPECIALLY ACROSS NORTHWEST OKLAHOMA. NEAR/JUST
ABOVE SEVERE WIND GUSTS MAY OCCUR FOR A FEW HOURS LATE THIS
AFTERNOON ACROSS FAR NORTHWEST OKLAHOMA. CONSIDERED A HIGH WIND
WARNING FOR 3 OR 4 COUNTIES BUT FOR NOW WILL KEEP THIS AREA IN A
WIND ADVISORY.
STORM CHANCES WITH THIS SYSTEM APPEAR TO BE LIMITED...AT LEAST IN
COVERAGE. THE NSSL WRF ATTEMPTS INITIATION NEAR THE DRYLINE LATE
IN THE AFTERNOON WITH PERHAPS A BETTER CHANCE ACROSS EASTERN PARTS
OF THE FA DURING THE EARLY TO MID EVENING. ANY STORM THAT CAN
REALIZE BETTER INSTABILITY...WILL POSE A RISK OF PRODUCING
DAMAGING WINDS AND LARGE HAIL.
ANOTHER TROUGH/SYSTEM WILL IMPACT THE SOUTHERN PLAINS THURSDAY INTO
FRIDAY. ALTHOUGH TEMPERATURES WILL BE RATHER WARM THURSDAY WITH
INCREASING WINDS...HUMIDITY LEVELS MAY REMAIN HIGH ENOUGH MOST
AREAS TO ALLEVIATE FIRE WEATHER CONCERNS. THIS SYSTEM WILL PUSH
A COLD FRONT ACROSS THE AREA LATE THURSDAY INTO FRIDAY. THE BEST
OPPORTUNITY FOR STORMS WILL BE ACROSS SOUTHEAST OKLAHOMA.
THIS SYSTEM WILL BRING SOME COOLER AIR FOR THE FIRST PART OF THE WEEKEND
BUT TEMPERATURES WILL WARM AGAIN GOING INTO EARLY NEXT WEEK. ANOTHER
SYSTEM MAY HELP INCREASE RAIN/STORM CHANCES NEXT TUESDAY INTO WEDNESDAY.
