   NWS STORM PREDICTION CENTER NORMAN OK
   1225 PM CDT THU JUN 06 2013

   AREAS AFFECTED...FL...SERN GA

   CONCERNING...TORNADO WATCH 283...

   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.
