...NO SVR TSTM AREAS FORECAST...
...SOUTHEAST INTO THE GULF COAST REGION...
SURFACE COLD FRONT EXTENDING ROUGHLY FROM THE MID ATLANTIC INTO THE
SRN APPALACHIANS AND CENTRAL GULF COAST AT MID MORNING WILL CONTINUE
ADVANCING SEWD THROUGH THE PERIOD. THIS WILL CONFINE RICH LOW LEVEL
MOISTURE...ALONG WITH APPRECIABLE INSTABILITY AND PRIMARY POTENTIAL
FOR SCATTERED THUNDERSTORMS...ACROSS THE SOUTHEAST AND GULF COAST
REGIONS TODAY. ALTHOUGH ABUNDANT LOW LEVEL MOISTURE AND SEASONABLY
WARM SURFACE CONDITIONS WILL BOOST MLCAPE TODAY...INSTABILITY WILL
BE TEMPERED BY RELATIVELY WARM TEMPERATURES ALOFT. IN
ADDITION...LIMITED DEEP LAYER SHEAR WILL PERSIST AS WSWLY FLOW
THROUGH THE MID/UPPER LEVELS REMAINS QUITE WEAK. THUS...A FEW
CLUSTERS OF STORMS WILL LIKELY INTENSIFY OVER PORTIONS OF
SRN/CENTRAL GA INTO SC/ERN-CENTRAL NC LATER TODAY AHEAD OF ADVANCING
FRONT...AND INVOF GULF/SEA BREEZES OVER FL/CENTRAL GULF COAST.
HOWEVER...OUTSIDE OF A FEW STRONG GUSTS...OVERALL RISK OF SEVERE
REMAINS QUITE LOW.
...SOUTHWEST INTO THE SRN ROCKIES...
POCKET OF RELATIVELY COOL MID LEVEL AIR BELOW MID/UPPER LEVEL
ANTICYCLONE OVER THE GREAT BASIN WILL LIKELY SUPPORT WEAK
INSTABILITY OVER PORTIONS OF SERN AZ INTO NRN NM/FAR SRN CO WITH
AFTERNOON HEATING. PW/S REMAIN AROUND .6 INCHES THIS MORNING WHICH
SHOULD BE SUFFICIENT FOR ISOLATED...NON-SEVERE THUNDERSTORMS OVER
HIGHER TERRAIN THIS AFTERNOON.
