...NO SVR TSTM AREAS FORECAST...

A WEST SOUTHWESTERLY FLOW PATTERN WILL BE IN PLACE OVER MUCH OF THE

STATES. AT THE SFC...A LARGE AREA OF HIGH PRESSURE WILL REMAIN OVER
THE ERN SEABOARD AND MS VALLEY SUNDAY KEEPING LOW-LEVEL MOISTURE IN
PLACE ACROSS FL. ELY ONSHORE FLOW ACROSS ERN FL WILL HELP ENHANCE
LOW-LEVEL CONVERGENCE WHICH ALONG WITH DESTABILIZATION WILL MAKE
SOME THUNDERSTORM DEVELOPMENT POSSIBLE SUNDAY AFTERNOON.
HOWEVER...INSTABILITY AND DEEP LAYER SHEAR ACROSS FL SHOULD NOT BE
SUFFICIENT FOR SEVERE THUNDERSTORM DEVELOPMENT. ELSEWHERE ACROSS THE
CONUS...THUNDERSTORM ACTIVITY IS NOT EXPECTED SUNDAY AND SUNDAY
