AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
630 PM CDT MON AUG 6 2012
.AVIATION...
00Z TAFS... SCATTERED SHOWERS/STORMS WILL AFFECT PARTS OF THE AREA
THIS EVENING. ACTIVITY MAY LINGER OVERNIGHT INTO TUES MORNING BUT
CHANCES TOO LOW FOR MENTION IN TAF. SHOWERS/STORMS WILL BE
POSSIBLE TUESDAY AFTERNOON WITH BEST CHANCE IN WESTERN OKLAHOMA
AND WESTERN NORTH TEXAS. VARIABLE AND GUSTY WINDS WILL BE POSSIBLE
NEAR ANY STORM.
&&
.PREV DISCUSSION... /ISSUED 359 PM CDT MON AUG 6 2012/
DISCUSSION...
AFTERNOON MOIST CONVECTION HAS INCREASED ALONG A SURFACE
TROUGH/STATIONARY BOUNDARY FROM SOUTHERN OK THROUGH WEST
CENTRAL OK. EXPECT MOST OF THIS ACTIVITY TO COME TO END AFTER
SUNSET TONIGHT...WITH ONLY MODEST MID LEVEL SUPPORT FROM A WEAK
SHORTWAVE TROUGH MOVING OVERHEAD WITHIN NW FLOW ALOFT. VERY
SIMILAR CONDITIONS WILL IMPACT THE FA TOMORROW THROUGH LATE
TOMORROW NIGHT. HIGHER DEWPOINTS ACROSS THE SOUTH WILL SUPPORT
HEAT INDEX VALUES HIGH ENOUGH FOR A HEAT ADVISORY TO BE ISSUED FOR
TOMORROW AFTERNOON. POPS WERE INCREASED A BIT...ESPECIALLY ACROSS
THE NORTHERN ZONES FOR TOMORROW NIGHT...AS SEVERAL SHORTWAVE
TROUGHS MOVE ACROSS THE SOUTHERN PLAINS THROUGH EARLY WED MORNING.
BY WEDNESDAY AFTERNOON...THE RIDGE WILL SHIFT WELL TO THE WEST AND
THE MOST POTENT SHORTWAVE TROUGH WILL TRAVERSE THE MIDWEST. BOTH
THE NORTHERLY FLOW ALOFT AND AN ASSOCIATED COLD FRONT WILL RESULT
IN INCREASED RAIN CHANCES WED. FOR NOW...THE BEST CHANCES APPEAR
THEY WILL BE ALONG AND SOUTH OF THE I44 CORRIDOR THROUGH LATE WED
NIGHT AND EARLY THURSDAY MORNING. THIS IS WHERE THE BEST MOISTURE
PROFILES WILL RESIDE ALONG AND JUST AHEAD OF THE FRONT. IF THE
FRONT AND SHORTWAVE TROUGH ARE SLOWER THAN EXPECTED...THEN POPS
MAY NEED TO BE SHIFTED NORTHWARD AND INCREASED FOR THE ENTIRE FA
THROUGH WED NIGHT. ALTHOUGH THE CENTER OF THE RIDGE WILL
GENERALLY REMAIN WEST OF THE FA THROUGH THE WEEK...ALL BUT THE GFS
CONTINUE TO SUGGEST VERY WARM 850MB TEMPS AND HIGHER THICKNESSES
SO WE HAVE REMAINED WELL ABOVE THE VERY COOL MEX AS A RESULT.
