AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
256 PM CDT MON JUL 16 2007

.DISCUSSION...
ISOLATED SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP
ACROSS EASTERN OKLAHOMA AND NORTHWEST ARKANSAS THIS AFTERNOON
AND INTO THE EARLY EVENING HOURS AS THE CAP ACROSS THE AREA
WEAKENS WITH DAYTIME HEATING. THE LARGEST CONCENTRATION OF
ACTIVITY WILL BE IN THE FAVORED TERRAIN AREAS OF SOUTHEAST OKLAHOMA
AND NORTHWEST ARKANSAS. THERE IS ALSO A BIT A MID-LEVEL SHEAR AXIS
IN PLACE ACROSS THE REGION THAT WILL AID IN THE DEVELOPMENT OF
THE THUNDERSTORMS.  SOME OF THESE STORMS COULD BECOME SEVERE WITH
DOWNBURST WINDS OF AROUND 65 MPH THE MAIN CONCERN. THIS ACTIVITY IS
EXPECTED TO DIMINISH AFTER SUNSET WITH THE LOSS OF HEATING.

WILL CONTINUE TO SEE ISOLATED AFTERNOON AND EVENING SHOWERS AND
THUNDERSTORMS THROUGH WEDNESDAY. WILL BEGIN TO INCREASE POPS ACROSS
NORTHEAST OKLAHOMA AND NORTHWEST ARKANSAS STARTING ON THURSDAY
WITH THE APPROACH OF A COLD FRONT. THE GFS AND ECMWF MODELS ARE IN
PRETTY GOOD AGREEMENT THAT THE FRONT WILL MOVE THROUGH THE AREA ON
FRIDAY. SO...I WILL TREND THE FORECAST IN THAT DIRECTION.  WILL GO
WITH CHANCE POPS AS THE FRONT MOVES THROUGH THE REGION WITH POPS TAPERING
OFF FROM THE NORTH FRIDAY NIGHT INTO SATURDAY.

A DRY PERIOD IS ANTICIPATED SATURDAY NIGHT THROUGH EARLY NEXT WEEK AS
HIGH PRESSURE BUILDS INTO THE REGION AT THE SURFACE AND ALOFT.
