VALID 161300Z - 171200Z

...NO SVR TSTM AREAS FORECAST...

COLD TROUGH WILL BE DEVELOPING INTO WRN U.S TODAY WITH MUCH OF ERN
U.S. UNDER A SLOWLY BUILDING FLAT RIDGE.  THE SUBTROPICAL STREAM
ACROSS THE GOM AND SRN FL FORECASTED TO SLOWLY WEAKEN AS ONE LAST
PERTURBATION TRAVERSES FL PENINSULA TODAY.

ANY THUNDERSTORMS THIS FORECAST PERIOD WILL BE CONFINED TO FAR S FL
WHERE A VERY MOIST AND WEAKLY UNSTABLE ENVIRONMENT EXISTS. 
SUFFICIENT LIFT ACROSS STATIONARY SFC BOUNDARY JUST S OF KEYS TO
MAINTAIN A LOW THREAT OF EMBEDDED THUNDERSTORMS THRU THE AFTERNOON. 


ONLY OTHER AREA WHERE A FEW STRIKES COULD OCCUR...MOSTLY TONIGHT...
WOULD BE SRN PLATEAU UNDER DEVELOPING COLD TROUGH. THREAT APPEARS TO
BE TOO LIMITED TO SUPPORT A 10% COVERAGE.
