...SYNOPSIS/FORECAST...
WATER VAPOR LOOPS THIS MORNING INDICATE A SHORTWAVE TROUGH
PROGRESSING EWD ACROSS THE ERN GULF OF MEXICO...AND THIS FEATURE IS
FORECAST TO TRACK ACROSS THE FL PENINSULA BEFORE EMERGING OVER THE
WATERS OF THE WRN NORTH ATLANTIC. MID-LEVEL ASCENT ACCOMPANYING THE
TROUGH WILL AID IN MAINTAINING MARGINAL INSTABILITY AMIDST SFC
DEWPOINTS IN THE MIDDLE 50S TO THE MIDDLE 60S. THESE FACTORS WILL
SUPPORT ISOLATED NON-SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE FL
PENINSULA...AND PORTIONS OF THE COASTAL PLAIN OF GA AND SRN SC.
GREATER THUNDERSTORM COVERAGE IS ANTICIPATED OFF THE COAST OF THE
ERN FL PENINSULA ATOP THE RELATIVELY WARM GULF STREAM CURRENT.
ELSEWHERE ACROSS THE LOWER 48 STATES...THE LACK OF ANY SUBSTANTIAL
INSTABILITY SHOULD PREVENT THE DEVELOPMENT OF THUNDERSTORMS THROUGH
THE PERIOD.
