   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 45 CONTINUES.
   
   SUMMARY...THE THREAT FOR TORNADOES AND DAMAGING WINDS APPEARS TO BE
   INCREASING FOR A SMALL PORTION OF THE FL PANHANDLE AND COASTAL BEND.
   
   DISCUSSION...TLH RADAR SHOWS A LINE OF SUPERCELLS ALONG A COLD FRONT
   WITH INLAND PORTION CURRENTLY ACROSS CALHOUN AND GULF COUNTIES. THE
   STRONGEST ROTATION WAS NOTED OFFSHORE WITH MULTIPLE CRESCENT SHAPED
   ECHOES. ONE SUCH STORM IS HEADING TOWARD APALACHICOLA AND MAY
   PRODUCE DAMAGING WINDS OR A TORNADO.
   
   INSPECTION OF FORECAST SOUNDINGS SUGGESTS DEWPOINTS FROM 68-70 F ARE
   REQUIRED FOR CLEARLY SURFACE BASED INFLOW PARCELS. THIS TYPE OF AIR
   MASS LIKELY EXISTS IN A NARROW CORRIDOR IMMEDIATELY AHEAD OF THE
   LINE INLAND AND OFFSHORE. GIVEN THE COOLER AIR MASS AWAY FROM THE
   COAST...THE GREATEST THREAT FOR TORNADOES AND STRONG WINDS WILL BE
   ACROSS COASTAL COUNTIES FOR THE NEXT SEVERAL HOURS. TLH HODOGRAPH
   MODIFIED FOR AAF WINDS RESULTS IN VERY LARGE HODOGRAPHS WITH 0-1 KM
   SRH OVER 600 M2/S2.
