VALID 061725Z - 061830Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 283 CONTINUES.

SUMMARY...TORNADO THREAT WILL CONTINUE ACROSS MUCH OF FL INTO SERN
GA AHEAD OF TROPICAL STORM ANDREA.

DISCUSSION...TROPICAL STORM ANDREA CONTINUES ITS NEWD MOVEMENT
TOWARD THE ERN BIG BEND REGION OF FL. CIRCULATION CENTER APPEARS TO
BE ROUGHLY 70 MI SW CTY AND AN EXTENSIVE CORRIDOR OF
CONVECTION/PRECIPITATION EXTENDS FROM THE NRN-ERN-SRN PERIPHERY OF
THIS FEATURE. PARTIAL HEATING ACROSS THE SRN PENINSULA APPEARS
PARTLY RESPONSIBLE FOR RECENT UPWARD GROWTH IN NUMEROUS SMALL
SUPERCELL STRUCTURES ACROSS THE SRN HALF OF THE WW WHERE SFC
TEMPERATURES HAVE WARMED TO NEAR 80F. THESE STRONGER UPDRAFTS WOULD
SEEM MORE CAPABLE OF PRODUCING TORNADOES AND LATEST WDSS-II LOW
LEVEL ROTATIONAL DATA SUPPORTS THIS IDEA EXHIBITING NUMEROUS
LONGER-LIVED STRUCTURES.
