   Valid 271200Z - 281200Z

   ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS
   WEST-CENTRAL AND SOUTHWESTERN FLORIDA...

   ...SUMMARY...
   A few tornadoes will be possible across parts of Florida Tuesday
   into Tuesday night, in association with Hurricane Ian.

   ...Synopsis...
   Large-scale upper troughing will continue over eastern NOAM Tuesday,
   while a second low/trough over the northeastern Pacific gradually
   approaches the Pacific Northwest.  In between, expansive ridging
   will extend from Texas and the Desert Southwest northward across the
   Rockies and into the Canadian Prairie Provinces.

   At the surface, a cold front will remain roughly in place from the
   southeastern U.S. Atlantic Coast, west-southwestward along the Gulf
   Coast vicinity.  To the south, Hurricane Ian is progged to be
   shifting slowly northward into/across the eastern Gulf of Mexico
   through the period.  Please refer to the latest forecasts regarding
   Ian from the National Hurricane Center.

   ...Florida Peninsula...
   As Ian moves slowly northward, the low-level flow across the Florida
   Peninsula south of the aforementioned cold front -- particularly
   across west-central and southwestern Florida -- will increase with
   time.  Widespread convection surrounding Ian will overspread the
   area from south to north, with embedded cellular convection within
   bands surrounding the center of circulation.  

   As the inland wind field gradually strengthens, potential for
   rotating cells will likewise increase, along with associated tornado
   potential.  This risk may increase through the afternoon, and
   continue into the overnight hours as the storm gradually shifts
   northward.
