AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
345 PM CDT WED MAY 26 2010

.DISCUSSION...
ONGOING SCATTERED CONVECTION WILL LIKELY CONTINUE A FEW HOURS PAST
SUNSET WITH ISOLATED STRONG DOWNBURSTS POSSIBLE. ADDITIONAL
FEATURES OF NOTE ARE LOCAL MID LEVEL VORT MAXIMA CURRENTLY AIDING
CONVECTION OVER WESTERN OKLAHOMA. LATEST RUC MAINTAINS THESE
FEATURES AND SLOWLY MOVES THEM EASTWARD HAVING THEM IN VICINITY
FOR THURSDAY. WHILE MOST MODEL DATA SUGGEST LESSER CONVECTIVE
COVERAGE THURSDAY AFTERNOON...MINIMAL CHANGE IN THE UNSTABLE AND
WEAKLY CAPPED AIRMASS ALONG WITH POTENTIAL UPPER FORCING AT LEAST
SUPPORTS ISOLATED THUNDERSTORM POTENTIAL FOR ALL AREAS. AGAIN
DAMAGING DOWNBURST WINDS WOULD BE POSSIBLE WITH THE STRONGEST
STORMS. FOLLOWED CLOSE TO PERSISTENCE FOR LOWS/HIGHS THROUGH TOMORROW.

HIGH PRESSURE TO CONTINUE TO BUILD INTO THE MISSISSIPPI RIVER
VALLEY AS UPPER LOW TRACKS FURTHER WESTWARD ACROSS THE SOUTHEASTERN
UNITED STATES. THIS ACTION WILL GRADUALLY USHER IN A DRIER AND
MORE STABLE AIRMASS ACROSS THE REGION BUT NOT BEFORE ANOTHER WARM
AND MUGGY DAY FRIDAY. WHILE ISOLATED STORMS ARE AGAIN POSSIBLE
THIS DAY...FORECAST SOUNDINGS SHOW WEAK YET DEEP DOWNWARD MOTION
ON OVERHEAD WHICH SHOULD LIMIT COVERAGE.

ABOVE NORMAL TEMPS CONTINUE THROUGH THE WEEKEND...WITH INITIALLY
DRIER DEWPOINTS QUICKLY RECOVERING SATURDAY INTO SUNDAY WITH HUMID
CONDITIONS RETURNING. FLOW ALOFT TO BECOME FLATTER ALLOWING WAVE
PASSING ACROSS THE NORTHERN PLAINS TO DRAG A FRONT THROUGH THE
AREA SUNDAY INTO MONDAY. THIS WILL BRING THE NEXT CHANCE OF A MORE
WIDESPREAD RAIN EVENT. TEMPERATURES AT OR ABOVE NORMAL WILL LIKELY
PERSIST INTO MUCH OF NEXT WEEK.
