0540 AM CDT SAT AUG 23 2008
AREAS AFFECTED...PARTS OF NRN FL INTO THE FL PANHANDLE
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 231040Z - 231245Z
TORNADO POTENTIAL APPEARS TO BE INCREASING. IT IS STILL UNCLEAR
WHETHER THIS WILL BE MORE THAN AN ISOLATED/BRIEF TORNADO THREAT
THROUGH MID MORNING...BUT TRENDS ARE BEING CLOSELY MONITORED.
AS THE CIRCULATION CENTER OF FAY CONTINUES TO SLOWLY MIGRATE WEST OF
THE FLORIDA BIG BEND REGION...AN INFLUX OF VERY MOIST BOUNDARY LAYER
AIR ON SOUTHERLY LOW-LEVEL FLOW OFF THE EASTERN GULF OF MEXICO IS
CONTRIBUTING TO DEEPENING CONVECTIVE DEVELOPMENT IN A DEVELOPING
CONFLUENCE BAND ON THE EASTERN PERIPHERY OF THE SYSTEM. THIS
EXTENDS SOUTH SOUTHWEST THROUGH NORTH NORTHWEST OF CROSS
CITY...WHERE LOW-LEVEL SHEAR IS NOT QUITE AS STRONG AS IN THE
EASTERLY REGIME FARTHER NORTH. HOWEVER...CLOCKWISE CURVED LOW-LEVEL
HODOGRAPHS ARE STILL SIZABLE AND SUPPORTIVE OF TORNADIC
POTENTIAL...PARTICULARLY WHERE THE BOUNDARY LAYER IS MOST UNSTABLE
NEAR IMMEDIATE COASTAL AREAS.
