AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
354 AM CDT MON JUN 20 2011

.DISCUSSION...
A LOT OF BUSINESS TO TAKE CARE OF THIS MORNING. FIRST OFF... ONE
MORE DAY OF VERY HOT TEMPERATURES ACROSS PORTIONS OF SW OK AND
N-TX WHERE THE AFTERNOON HEAT INDEX VALUES WILL RANGE FROM 105 TO
NEAR 110. GIVEN THE CUMULATIVE HEAT AND WARM OVERNIGHT
TEMPERATURES OF THE PAST SEVERAL DAYS... WILL CARRY A HEAT
ADVISORY AGAIN FOR THIS AFTERNOON. MEANWHILE... THE STRONG SOUTH
TO SOUTHWEST WINDS TODAY WILL COMBINE WITH LOW HUMIDITIES AND HOT
TEMPERATURES TO ONCE AGAIN CREATE EXTREME WILDFIRE CONDITIONS
ESPECIALLY OVER THE WESTERN PORTIONS OF OK AND N-TX. SPEAKING OF
THE WINDS... WILL CONTINUE THE CURRENT WIND ADVISORY INTO MUCH OF
THE MORNING AS SPEEDS CURRENTLY ARE SUSTAINED AT 30 MPH WITH
GUSTS FREQUENTLY ABOVE 40 MPH IN SEVERAL LOCATIONS. SHOULD SEE THE
EXCESSIVE SPEEDS DIMINISH SOMEWHAT BY LATE MORNING ALTHOUGH IT
WILL CONTINUE TO BE QUITE BREEZY THROUGH THE REMAINDER OF THE DAY.

WHILE SOME ISOLATED SHOWERS NOT OUT OF THE QUESTION THIS
MORNING... THE BEST RAIN CHANCES WILL BE LATER THIS AFTERNOON AND
TONIGHT. A STRONG UPPER LEVEL STORM SYSTEM LOCATED OVER CENTRAL
AND SOUTHERN ROCKIES THIS MORNING WILL MOVE OUT INTO THE CENTRAL
AND SOUTHERN PLAINS LATER TODAY AND TONIGHT. THIS SHOULD WEAKEN
THE CAP OVER THE REGION WHILE ALSO PUSHING A DRYLINE AND MERGING COLD
FRONT SOUTHEAST ACROSS THE CWA. EXPECT T-STORMS TO DEVELOP NEAR
THE COLD FRONT AND DRYLINE BY MID TO LATE AFTERNOON FROM N-CENTRAL
OK INTO PORTIONS OF SW OK AND WESTERN N-TX. ACTIVITY WILL CONTINUE
TO ADVANCE EASTWARD DURING THE EVENING. UNFORTUNATELY IT APPEARS
THAT THE FAR WESTERN PORTIONS OF THE CWA WILL AGAIN BE WATER-STARVED
AS MOST OF THE ACTIVITY WILL OCCUR FARTHER TO THE EAST. SOME
SEVERE STORMS WILL LIKELY OCCUR THROUGH THIS EVENING... PRODUCING
STRONG WINDS AND LARGE HAIL. SURFACE WINDS BEHIND THE FRONT MAY
BECOME QUITE GUSTY ACROSS NW OK TONIGHT AS SPEEDS AROUND 500
METERS ARE FORECAST TO REACH 40 KTS.

SCATTERED STORMS MAY LINGER MAINLY ACROSS THE SOUTH AND EAST
TOMORROW AND TOMORROW NIGHT. THE FRONT WILL USHER OUT THE VERY
HOT TEMPERATURES THAT HAVE PLAGUED MUCH OF WESTERN OK AND N-TX THE
PAST SEVERAL DAYS... RESULTING IN HIGHS ON TUESDAY TO FINALLY DROP BELOW
100 DEGREES... JUST IN TIME FOR THE FIRST DAY OF SUMMER.

IN THE LONGER TERM... DRY WEATHER IS EXPECTED ON WEDNESDAY. WE WILL
MAINTAIN LOW POPS ACROSS MAINLY THE NORTHWEST HALF OF THE CWA FROM
THURSDAY INTO THE WEEKEND FOR THE POSSIBILITY THAT A FEW STORMS
THAT DEVELOP OVER THE COLORADO HIGH PLAINS INTO KANSAS MAY
EVENTUALLY DRIFT INTO PARTS OF OK. TEMPERATURES WILL BEGIN TO
CREEP BACK INTO THE TRIPLE DIGITS OVER PARTS OF SW OK AND N-TX BY
THURSDAY OR FRIDAY... BUT LIKELY NOT TO THE EXCESSIVELY HIGH
VALUES OBSERVED IN MANY AREAS OVER THE PAST SEVERAL DAYS.
