1219 PM CDT TUE APR 26 2005

AREAS AFFECTED...NRN FL...SRN GA

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 261719Z - 261915Z

AREA IS BEING MONITORED FOR POSSIBLE WW.

SURFACE RIDGING ACROSS EASTERN GULF/SOUTH ATLANTIC COASTAL AREAS IS
BEGINNING TO SLOWLY WEAKEN...AS LOW-LEVEL WARM ADVECTION REGIME
OVERSPREADS REGION...DOWNSTREAM OF APPROACHING LARGE-SCALE TROUGH
AXIS.  SIGNIFICANT INCREASES IN SURFACE TEMPERATURES/DEW POINTS HAVE
BECOME EVIDENT ALONG NORTHERN FLORIDA GULF COASTAL AREAS...AND
INLAND THERMAL/MOISTURE ADVECTION WILL CONTINUE THIS AFTERNOON.

ONGOING CONVECTIVE ACTIVITY ACROSS THE FLORIDA PANHANDLE APPEARS TO
BE SUPPORTED BY ENHANCED DIVERGENT UPPER FLOW FIELD BETWEEN
INTERACTING BELTS OF STRONGER FLOW ACROSS THE SOUTHEAST.  THIS IS
EXPECTED TO SPREAD ACROSS THE REMAINDER OF NORTHERN FLORIDA/
SOUTHERN GEORGIA THROUGH THE REMAINDER OF THE AFTERNOON.

VERTICAL SHEAR PROFILES ARE CURRENTLY VERY FAVORABLE FOR SUPERCELLS.
 THOUGH LOW-LEVEL HODOGRAPHS MAY WEAKEN SOME AS LOW-LEVEL JET VEERS
THIS AFTERNOON...ONGOING DESTABILIZATION OF BOUNDARY LAYER MAY
COMPENSATE FOR THIS...SUPPORTING RISK FOR AN ISOLATED TORNADO OR
TWO.
