...NO SVR TSTM AREAS FORECAST...
...SERN STATES...
ALTHOUGH UPPER LEVEL LOW IS LOCATED WELL NWWD OF THE REGION IN THE
GREAT LAKES AREA...RELATIVELY STRONG MID LEVEL FLOW AND WEAK
SHORTWAVE TROUGHS WERE TRAVERSING NEWD FROM THE SOUTH CENTRAL GULF
OF MEXICO ACROSS THE ATLANTIC COASTAL STATES THIS EVENING. A COLD
FRONT STRETCHED FROM THE UPPER OH VALLEY SSWWD INTO THE SRN
APPALACHIANS...BUT THE STRONGEST SURFACE CONVERGENCE WAS LOCATED
WITH A TROUGH THAT EXTENDED FROM THE CENTRAL CAROLINAS SWWD INTO THE
ERN FL PANHANDLE. MUCAPE VALUES RANGED FROM AROUND 1200 J/KG IN THE
FL PENINSULA TO LESS THAN 500 J/KG IN SERN GA/ERN CAROLINAS.
THUNDERSTORMS ARE EXPECTED BE MOST NUMEROUS ACROSS THE FL PENINSULA
WHERE INSTABILITY WILL BE THE GREATEST. HOWEVER... ISOLATED
THUNDERSTORMS ARE ALSO POSSIBLE THIS EVENING ALONG AND EAST OF THE
SURFACE TROUGH WHERE MASS CONVERGENCE SHOULD PROVIDE SUFFICIENT LIFT
FOR CONVECTION.
