AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
253 PM CDT THU JUL 16 2009

.DISCUSSION...
SCATTERED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED THIS
AFTERNOON ACROSS EAST-CENTRAL OKLAHOMA AND WEST-CENTRAL
ARKANSAS IN THE VICINITY OF AN OUTFLOW BOUNDARY LEFT OVER
FROM LAST NIGHTS CONVECTION. THIS BOUNDARY IS CURRENTLY
LOCATED NEAR A KRUE-KMLC-KSNL LINE. OTHER SCATTERED SHOWERS
AND THUNDERSTORMS HAVE BEGUN TO DEVELOP ACROSS SOUTHEAST
KANSAS AND EVEN INTO NORTHEAST OKLAHOMA IN ASSOCIATION WITH
AN OUTFLOW BOUNDARY LEFT OVER FROM THE DECAYING NORTHERN
KANSAS MCS. THIS BOUNDARY IS GENERALLY FROM A KMCI-KCFV-KPNC.
THIS DEVELOPMENT IS BEING ENHANCED BY A MID-LEVEL SHORTWAVE
MOVING FROM THE CENTRAL PLAINS IN THE MISSISSIPPI VALLEY.
ANY OF THESE STORMS WILL HAVE THE POTENTIAL TO BECOME
SEVERE LATE THIS AFTERNOON AND INTO THIS EVENING AS THE
AIRMASS ACROSS THE REGION CONTINUES TO DESTABILIZE. THE MAIN
CONCERNS WILL BE WIND GUSTS TO AROUND 70 MPH AND LARGE HAIL.
THE THREAT FOR SHOWERS AND THUNDERSTORMS WILL DIMINISH OVERNIGHT
AS THE SYNOPTIC COLD FRONT THAT IS CURRENTLY ACROSS NORTHERN KANSAS
SWEEPS THROUGH THE REGION LATER TONIGHT AND INTO FRIDAY MORNING.

THE EXCESSIVE HEAT WARNING WILL BE ALLOWED TO EXPIRE AT 7 PM ACROSS
EXTREME SOUTHEAST OKLAHOMA AS THE HEAT IS EXPECTED TO BREAK AFTER
THIS AFTERNOON WITH THE APPROACH OF THE AFOREMENTIONED COLD FRONT.

NOTICEABLY COOLER AND DRIER CONDITIONS ARE EXPECTED THROUGH THE
WEEKEND AND INTO EARLY NEXT WEEK AS HIGH PRESSURE BUILDS IN THE
WAKE OF THE COLD FRONT AND THE UPPER LEVEL RIDGE RESPONSIBLE FOR
THE MINI HEATWAVE RETREATS TO THE WEST.

WILL SEE ANOTHER CHANCE OF SHOWERS MONDAY NIGHT INTO TUESDAY AS
A FRONTAL BOUNDARY APPROACHES THE AREA.
