AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
300 PM CDT FRI APR 30 2010

.DISCUSSION...
SCATTERED STRONG TO SEVERE THUNDERSTORMS CONTINUE ALONG PACIFIC
FRONT/DRYLINE STRETCHING FROM FAR NWRN AR INTO SERN OK. LOW LEVEL
MOISTURE IS OBVIOUS...WITH SFC DEWPOINTS RUNNING CLOSE TO 70F IN SE
OK...AND THUNDERSTORMS HAVE SHOWN A SIGNIFICANT INCREASE IN
INTENSITY OVER THE PAST 1-2 HOURS. WITH SFC BASED CAPES RUNNING
AROUND 1500 J/KG AND STRONG SHEAR IN PLACE (0-6KM SHEAR AROUND
50KTS)...EXPECT SEVERE THUNDERSTORMS TO CONTINUE THE REMAINDER OF
THE AFTERNOON AND INTO THE EARLY EVENING BEFORE EXITING THE FORECAST
AREA. DISCRETE SUPERCELL DEVELOPMENT...INCLUDING A TORNADIC
POTENTIAL...WILL BE POSSIBLE.

FOR TOMORROW...WEAK SURFACE FRONT/DEWPOINT BOUNDARY SHOULD LAY
ACROSS SE OK/WCNTRL AR SATURDAY MORNING...AND MAY LIFT N SOME IN
RESPONSE TO SFC PRESSURE FALLS/WEAK CYCLOGENESIS OVER ERN TX. WEAK
CAP WILL LIKELY EXIST S OF THE BOUNDARY EARLY IN THE DAY...BUT
SHOULD EVENTUALLY DEVELOP ENOUGH INSTABILITY FOR SCT TSTM DEVELOP IN
THE WARM SECTOR BY LATE MORNING OR EARLY AFTERNOON. FORECAST BULK
SHEAR APPEARS SUFFICIENT TO SUPPORT A FEW SEVERE STORMS...MAINLY
ACROSS FAR SERN OK INTO WCNTRL AR.

BULK OF SHORT RANGE GUIDANCE ALSO DEVELOP A PROMINENT ZONE OF
ISENTROPIC UPLIFT (300-305K SFC) ACROSS CNTRL OK...WITH A SECONDARY
BAND OF PRECIPITATION DEVELOPING FROM CNTRL OK INTO NE OK LATE IN
THE DAY AND INTO THE EVENING.

UPPER FLOW REMAINS SWLY INTO SUNDAY...ALTHOUGH BEST LOW-LEVEL
MOISTURE SHOULD BE SHUNTED TO OUR E BY THIS TIME. WILL HANG ON TO
SOME LOW POPS MAINLY ACROSS FAR ERN OK AND WRN AR. WEAK SFC BOUNDARY
MAKES A RUN AT THE AREA ON MONDAY...BUT PLAN ON KEEPING FORECAST DRY
AS MOISTURE REMAINS MARGINAL.

EXTENDED...
A PIECE OF THE MEAN WRN TROF SHOULD BREAK OFF AND PUSH E ACROSS TX
MONDAY NIGHT INTO TUESDAY. CURRENT THINKING IS THAT THIS SYSTEM
SHOULD REMAIN JUST FAR ENOUGH S TO PRECLUDE POPS FOR OUR AREA.

12Z ECMWF/GFS IN REASONABLE AGREEMENT FOR THE REMAINDER OF THE WEEK.
SLY FLOW AHEAD OF APPROACHING FRONT WILL BE FAVORABLE FOR VERY WARM
AFTERNOON TEMPS BOTH TUESDAY AND WEDNESDAY. DIFFERENCES NOTED IN
TIMING OF FRONT BY THURSDAY...AND HAVE SIDE WITH THE SLOWER ECMWF
FOR NOW. COOLER WEATHER LIKELY BY THE END OF THE WEEK AS THE FRONT
FINALLY PUSHES S OF THE AREA.
