VALID 081200Z - 091200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
BROAD CYCLONIC FLOW WILL BE PRESENT IN THE MID/UPPER LEVELS OVER THE
CNTRL/ERN CONUS...WHILE ONE EMBEDDED SHORTWAVE TROUGH MOVES SEWD
ACROSS PARTS OF THE NRN/CNTRL PLAINS AND A SECOND EMBEDDED SHORTWAVE
TROUGH MOVES FROM THE OH VALLEY TOWARD THE MID-ATLANTIC AND OFF THE
EAST COAST. FARTHER WEST...A MID/UPPER-LEVEL RIDGE WILL BUILD NNEWD
ACROSS PARTS OF THE NWRN STATES...WHILE A CLOSED LOW OVER THE FAR
ERN PACIFIC MOVES SSEWD NEAR THE COAST OF BAJA CALIFORNIA.

...S FL THIS AFTERNOON...
NWLY TO NLY FLOW BEHIND A REMNANT SFC FRONT...ORIENTED NE TO SW
ACROSS THE SRN FL PENINSULA...WILL EXPAND SWD AND COVER A LARGER
PART OF S FL TODAY COMPARED TO YESTERDAY. THIS WILL OCCUR AS WEAK
SFC LOW PRESSURE SHIFTS NEWD ACROSS THE SWRN N ATLANTIC. IN
RESPONSE...THE BOUNDARY LAYER WILL BECOME LESS MOIST/UNSTABLE AS
RELATIVELY DRIER AIR OVER NRN/CNTRL PARTS OF THE FL PENINSULA IS
TRANSPORTED SWD. AN EXCEPTION MAY EXIST OVER A NARROW CORRIDOR
ADJACENT TO THE FAR SERN COAST INCLUDING ERN BROWARD AND ERN
MIAMI-DADE COUNTIES AND THE UPPER KEYS. IN THIS AREA...THE
BACKGROUND SFC PRESSURE GRADIENT IS FORECAST TO REMAIN SUFFICIENTLY
WEAK TO POTENTIALLY SUPPORT THE DEVELOPMENT OF A COASTAL SEA BREEZE
CONVERGENCE ZONE...OWING TO DIABATIC HEATING OVER LAND. THE INFLUX
OF THE MARINE LAYER IN ASSOCIATION WITH THE SEA BREEZE CIRCULATION
COINCIDENT WITH PEAK HEATING MAY INCREASE BUOYANCY WITHIN THE
AFOREMENTIONED CORRIDOR. AND...WITH LOW-LEVEL CONVERGENCE ATTENDANT
TO THE SEA BREEZE BOUNDARY...AN ISOLATED THUNDERSTORM OR TWO WILL BE
POSSIBLE IN THIS CORRIDOR.

...DEEP S TX TODAY...
WEAK WAA ABOVE THE RELATIVELY COOL LAYER IN THE LOW LEVELS IS ONLY
EXPECTED TO SUPPORT VERY WEAK ELEVATED INSTABILITY /MUCAPE VALUES
BELOW 100 J PER KG/. AS SUCH...THE THREAT FOR THUNDERSTORMS IS TOO
LOW FOR ANY THUNDER PROBABILITIES AT THIS TIME.
