   ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON
   OVER PARTS OF SOUTHERN ALABAMA...THE FLORIDA PANHANDLE...AND
   SOUTHWEST GEORGIA....

   ...SUMMARY...
   A few severe thunderstorms will be possible this afternoon across
   parts of the north-central/northeastern Gulf Coast region.  Damaging
   gusts will be the main concern, and a tornado is possible.

   ...Gulf Coast Region...
   A strong surface cold front and associated line of showers and
   thunderstorms is progressing eastward across southeast LA and
   southern MS.  Convective intensity has been modest this morning,
   with relatively weak CAPE and cool surface temperatures being
   limiting factors.  Visible satellite imagery shows partial heating
   occurring from Mobile Bay eastward, where temperatures will warm
   into the mid/upper 70s.  Destabilization and steepening low-level
   lapse rates should result in some intensification and increasing
   risk of robust storms by mid-afternoon over southern AL, the FL
   panhandle, and southwest GA.  Forecast soundings show relatively
   veered low-level winds and moderately strong westerly flow aloft. 
   This may result in a few bowing structures capable of locally
   damaging wind gusts and perhaps a brief tornado or two.
