230 PM CDT FRI AUG 24 2007

.DISCUSSION...
THUNDERSTORMS HAVE CONTINUED TO DEVELOP MOST OF THE DAY FROM WRN INTO
NERN OK...ALONG/NEAR OLD OUTFLOW BOUNDARY AND BROAD ZONE OF
DIFFERENTIAL HEATING. PERSISTENT CLOUD COVER HAS HELD DOWN
INSTABILITY SOME...BUT AREAS ACROSS NE OK SHOULD HAVE THE BEST LATE
AFTERNOON SHEAR (0-6KM AROUND 35-40 KTS). ACCORDINGLY...A FEW SEVERE
THUNDERSTORMS WILL BE POSSIBLE THE REMAINDER OF THE DAY.

WILL ALSO NEED TO KEEP AN EYE ON THE HEAVY RAINFALL POTENTIAL ACROSS
NE OK. PWS ARE RUNNING AROUND 2 INCHES AND VERY IMPRESSIVE H85
MOISTURE TRANSPORT WAS NOTED ACROSS NCTNRL/NERN OK. TRAINING OF
CELLS ALONG THE WEAK OUTFLOW(S) REMAINS A DISTINCT
POSSIBILITY...WITH LOCALLY HEAVY RAINFALL POSSIBLE. THE MOST
SIGNIFICANT RAINFALL OVER THE PAST WEEK HAS REMAINED S OF THE AREA
OF CONCERN...SO WE/RE NOT PLANNING ON ANY FLASH FLOOD HEADLINES AT
THIS TIME.

SURFACE BOUNDARY(S) EXPECTED TO PUSH INTO SE OK/WCNTRL AR BY
SATURDAY. PRIMARY FOCUS FOR STORMS SHOULD REMAIN W...BUT WITH
BOUNDARY ACROSS THE REGION...WILL MAINTAIN 20/30 POPS.

BOUNDARY SHOULD WASH OUT BY SUNDAY...WITH SLY FLOW RETURNING. SHOULD
BE ANOTHER HOT AND STICKY DAY...WITH TEMPS BOUNCING BACK INTO THE
MID/UPPER 90S.

EXTENDED (TUESDAY THROUGH FRIDAY)...
UPPER FLOW WILL GRADUALLY BECOME MORE AMPLIFIED DURING THIS
PERIOD...WITH NWLY FLOW DEVELOPING ACROSS THE REGION AS RIDGE BUILDS
IN THE WRN STATES.

AFTER ANOTHER HOT DAY ON TUESDAY...PLAN ON INTRODUCING LOW POPS
WEDNESDAY AS WEAKNESSES IN THE UPPER FLOW APPEAR AND COLD FRONT
NEARS. GFS/ECMWF IN REASONABLE AGREEMENT THAT FRONT WILL MOVE
THROUGH THE AREA THURSDAY...WITH DRIER AIR FILTERING S THURSDAY
NIGHT INTO FRIDAY. IF THIS HOLDS TRUE...LESS OPPRESSIVE TEMPS ARE IN
THE OFFING...WITH OVERNIGHT LOWS IN THE 60S GOING INTO NEXT WEEKEND.

DISCUSSION...
SHOWERS AND THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON ALONG AND NORTH
OF AN OUTFLOW BOUNDARY THAT EXTENDS FROM NEAR SPRINGFIELD MISSOURI
TO NEAR TULSA OKLAHOMA. THIS ACTIVITY WILL CONTINUE TO INCREASE
THROUGH THE AFTERNOON AND INTO THE EVENING HOURS AS THE AIRMASS ACROSS
THE REGION BECOMES INCREASINGLY UNSTABLE. SOME OF THE THUNDERSTORMS
COULD BECOME SEVERE THIS AFTERNOON AND EVENING. WIND GUSTS OF 80 MPH
AND LARGE HAIL WILL BE THE PRIMARY CONCERN. HOWEVER...THERE WILL BE
ADEQUATE DEEP LAYER SHEAR FOR SUPERCELL DEVELOPMENT. THE THREAT FOR
SEVERE THUNDERSTORMS WILL SUBSIDE AS WE MOVE INTO THE OVERNIGHT HOURS.

AS THE SEVERE WEATHER THREAT DIMINISHES...THE RISK FOR HEAVY RAIN
WILL INCREASE AS THE LOW LEVEL JET INCREASES OVERNIGHT AND AN
UPPER LEVEL DISTURBANCE SWEEPS ACROSS THE REGION.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
SPOTTER ACTIVATION MAY BE NEEDED.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
SATURDAY...THUNDERSTORM POTENTIAL.
SUNDAY...DANGEROUS HEAT POTENTIAL.
MONDAY...DANGEROUS HEAT POTENTIAL.
TUESDAY...NO HAZARDS.
WEDNESDAY...THUNDERSTORM POTENTIAL.
THURSDAY...THUNDERSTORM POTENTIAL.

EXTENDED DISCUSSION...
THUNDERSTORMS FROM TONIGHT MAY LINGER INTO THE DAY SATURDAY.
DRY AND WARM WEATHER WILL OCCUR AS HIGH PRESSURE ALOFT WILL
CONTROL THE WEATHER EARLY NEXT WEEK.  THUNDERSTORM CHANCES
WILL RETURN TO THE FORECAST DURING THE MIDDLE OF NEXT WEEK
AS A COLD FRONT MAY MOVE INTO THE AREA.
