AREAS AFFECTED...FL PENINSULA NWD TO SRN GA

VALID 071747Z - 071915Z

ISOLATED WET MICROBURSTS AND MARGINALLY SEVERE HAIL POSSIBLE THROUGH
THE AFTERNOON ACROSS MUCH OF THE FL PENINSULA NWD INTO SRN GA.

AIR MASS ACROSS FL INTO SRN GA HAS BECOME VERY UNSTABLE /MLCAPE
3000+ J/KG/...GIVEN COOL MID-LEVEL TEMPERATURES /AROUND -8 C AT 500
MB/ COMBINED WITH A WARM AND VERY MOIST BOUNDARY LAYER. 
THUNDERSTORMS...A FEW STRONG...HAVE ALREADY DEVELOPED ALONG THE FL
WEST COAST SEA BREEZE AND ALONG A WEAK SURFACE BOUNDARY MOVING EWD
ACROSS SRN GA. ADDITIONAL STORMS WILL DEVELOP ALONG THESE SURFACE
BOUNDARIES AND LAKE/CONVECTIVE OUTFLOW BOUNDARIES AS THE AIR MASS
CONTINUES TO DESTABILIZE THIS AFTERNOON.  WEAK DEEP LAYER SHEAR WILL
TEND TO FAVOR PULSE-TYPE STORMS...WITH FAIRLY HIGH FREEZING/WET-BULB
ZERO HEIGHTS AND A MOIST ENVIRONMENT SUPPORTING WET MICROBURSTS AS
THE PRIMARY THREAT.
