   Day 1 Convective Outlook

   Valid 281630Z - 291200Z

   ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS MAINLY THIS
   AFTERNOON/EVENING ACROSS EAST CENTRAL FL...

   ...SUMMARY...
   Tornadoes are expected this afternoon/evening, especially across
   east central Florida, in association with Major Hurricane Ian.

   ...East central FL this afternoon/evening...
   Major Hurricane Ian is approaching the FL Gulf coast near Fort Myers
   and Port Charlotte, and the storm core will continue to move
   northeastward across central FL through tonight (see latest NHC
   advisories for additional information).  Visible satellite imagery
   reveals a zone of filtered surface heating along the Atlantic coast,
   to the east of the thicker clouds with the hurricane core along the
   Gulf coast, as discussion in MD 1841.  Also, low-level flow has
   veered and hodographs have become less favorable for supercells
   across the Keys, while the stronger low-level shear/hodograph
   curvature will persist through the afternoon/evening across east
   central FL.  As new convection forms in the zone of stronger surface
   heating, tornadoes will be possible as supercells move northward
   into the weak baroclinic zone across central/east central FL, with a
   diminished threat farther northwest and deeper into the rain-cooled
   air.  This baroclinic zone may shift slowly northward along the
   Atlantic coast though early tonight, in advance of the hurricane
   core.
