AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
318 AM CDT WED AUG 20 2014

.DISCUSSION...
WEAK UPPER VORT MAX CURRENTLY OVER NORTH TEXAS WILL LIFT NNE TODAY
INTO THE REGION AROUND DEVELOPING UPPER HIGH OVER THE GULF COAST STATES.
THIS SHOULD PROVIDE AT LEAST A LIMITED CHANCE FOR ISOLATED SHOWERS/
THUNDERSTORMS ACROSS EASTERN OKLAHOMA AND NORTHWEST ARKANSAS THIS
AFTERNOON. IN ADDITION...POTENTIAL FOR INCREASED CLOUD COVER COULD
KEEP HIGH TEMPERATURES A DEGREE OR TWO COOLER THAN WOULD OCCUR
OTHERWISE.

MAIN WEATHER STORY WILL BE THE HOT/HUMID CONDITIONS AS THE SLOW
WARMING TREND CONTINUES THROUGH THE WEEKEND AS UPPER HIGH BUILDS
INTO THE ARKLATX REGION. HEAT INDICES IN THE 100-105 DEGREE RANGE
ARE LIKELY EACH AFTERNOON THURSDAY THROUGH SATURDAY. UPPER HIGH
BEGINS DRIFTING NORTH IN MIDDLE MISSISSIPPI RIVER VALLY INTO EARLY
NEXT WEEK WHICH MAY SHAVE A COUPLE OF DEGREES OFF OF HIGHS...HOWEVER
ABOVE NORMAL TEMPERATURES ARE EXPECTED TO CONTINUE THROUGH THE
EXTENDED PERIODS. LIMITED PRECIPITATION CHANCES RETURN BY TUESDAY
OF NEXT WEEK AS LOW LEVEL MOISTURE BEGINS TO INCREASE. GENERALLY
STAYED CLOSE TO THE WARMER ECMWF GUIDANCE THROUGH THE WEEKEND
GIVEN RECENT TEMP TRENDS OVER THE LAST FEW DAYS.
