AREAS AFFECTED...FL...SRN GA

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 041653Z - 041830Z

THUNDERSTORMS WILL INCREASE IN COVERAGE ACROSS NRN/CNTRL FL AND SRN
GA OVER THE NEXT FEW HOURS. DAMAGING WINDS WILL BE POSSIBLE WITH THE
STRONGER CELLS. A WW MAY BECOME NECESSARY EARLY THIS AFTERNOON
ACROSS THE REGION.

LATEST WATER VAPOR IMAGERY SHOWS A WELL-DEFINED CIRCULATION MOVING
ACROSS NCNTRL FL ATTM. LARGE-SCALE ASCENT ON THE NRN SIDE OF THE
CIRCULATION WILL MOVE EWD ACROSS NRN FL AND SRN GA THIS AFTERNOON
AIDING SCATTERED THUNDERSTORM DEVELOPMENT. SFC DATA SHOWS DEWPOINTS
RANGING FROM 70 TO 75 F ACROSS MUCH OF THE REGION WITH AN AXIS OF
INSTABILITY EXISTING FROM SE GA SWD ACROSS NRN AND CNTRL FL WHERE
MLCAPE VALUES RANGE FROM 2000 TO 3500 J/KG. IN ADDITION...THE
WSR-88D VWP FROM TALLAHASSEE SHOWS ABOUT 30 KT OF DEEP LAYER SHEAR
WHICH SHOULD BE SUFFICIENT FOR STRONG TO SEVERE MULTICELL STORMS.
STEEPENING LOW-LEVEL LAPSE RATES MAINLY FROM TALLAHASSEE EWD SHOULD
RESULT IN ISOLATED DAMAGING WIND GUSTS WITH THE STRONGER CELLS.
