   VALID 031047Z - 031145Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 67 CONTINUES.
   
   AN ISOLATED TORNADO THREAT MAY DEVELOP ACROSS PARTS OF SW GA...SE AL
   AND THE FL PANHANDLE TOWARD DAYBREAK. WW ISSUANCE MAY BE NEEDED
   LATER THIS MORNING AS CELLS INCREASE IN COVERAGE. WW 67 WILL BE
   ALLOWED TO EXPIRE AT 11Z.
   
   CONVECTION IS STARTING TO INCREASE IN COVERAGE FROM THE FL PANHANDLE
   NEWD ACROSS SW GA ACROSS A WARM SECTOR WITH SFC DEWPOINTS IN THE MID
   TO UPPER 60S F. THIS ACTIVITY IS WELL AHEAD OF COLD FRONT WHICH WILL
   MOVE INTO THE FL PANHANDLE THIS MORNING. AS THE COLD FRONT
   APPROACHES...A LINE OF CONVECTION SHOULD GRADUALLY ORGANIZE AS IS
   SUGGESTED BY SHORT-TERM MODEL FORECASTS. IN ADDITION...A LOW-LEVEL
   JET MAX IS FORECAST TO DEVELOP ACROSS NRN FL THIS MORNING HELPING
   SHEAR PROFILES TO BECOME MORE FAVORABLE FOR STORM ROTATION. ALTHOUGH
   THE MORE SUBSTANTIAL TORNADO THREAT SHOULD BE DELAYED UNTIL LATER
   MORNING AS SFC TEMPS WARM...AN ISOLATED TORNADO THREAT CAN NOT BE
   RULED OUT AROUND DAYBREAK DUE TO THE LOW-LEVEL SHEAR ENVIRONMENT
   ALREADY IN PLACE.
