   Day 1 Convective Outlook

   Valid 300100Z - 301200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Appreciable severe risk has diminished, with severe weather unlikely
   overnight.

   ...Discussion...
   Evening RAOBs confirm an overall lack of CAPE depicted by objective
   analyses this evening, and suggested by the general decrease in
   lightning observed over the past hour.

   While the deep-layer wind field remains quite strong, the lack of
   available instability suggests that storms will continue to
   gradually weaken over the next several hours.  By the end of the
   period, the band of showers -- and possibly some sporadic lightning
   -- should extend from the mid-Atlantic region to southeast Georgia
   and eastern portions of the Florida panhandle and the adjacent
   northern Florida Peninsula, with the cold front in lee of the
   Appalachians.

   Elsewhere, lightning has ceased over the central High Plains, with
   showers continuing to diminish.  Additional/appreciable lightning is
   not expected.
