THUNDERSTORMS WILL CONTINUE DEVELOPING OVER PORTIONS OF THE SRN FL

BOUNDARY EXTENDS FROM NEAR SARASOTA SEWD TO N OF LAKE OKEECHOBEE.
OTHER BOUNDARIES EXIST FROM S OF LAKE OKEECHOBEE TO NEAR MIAMI. THE
ATMOSPHERE REMAINS MODERATELY UNSTABLE WITH MINIMAL CAP...AND STORMS
SHOULD CONTINUE DEVELOPING NEXT FEW HOURS. VERTICAL SHEAR PROFILES
ARE WLY UNIDIRECTIONAL...GENERALLY AOB 25 KT AND SUPPORTIVE OF
MULTICELLS.

SURFACE HEATING HAS BEEN MODERATED BY ANVIL DEBRIS. ALSO DEWPOINTS
HAVE BEEN IN THE PROCESS OF MIXING DOWNWARD SIGNIFICANTLY ALONG
PORTIONS OF THE SWRN COAST...POSSIBLY DUE IN PART TO THE INFLUENCE
