   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   A few thunderstorms are expected over the Florida Peninsula today.

   ...Synopsis...
   A pair of low-amplitude shortwave troughs -- one currently entering
   the central High Plains and the other traversing the northern
   Rockies -- will move southeastward within the northwesterly flow
   aloft extending from the northern High Plains into the Southeast.
   High surface pressure will dominant the eastern CONUS while lee
   troughing deepens across the High Plains. Despite this relatively
   progressive pattern, a dry and stable continental airmass will
   continue to preclude thunderstorms across the majority of the
   central and eastern US. The only exception is across FL where
   isolated to scattered thunderstorms are possible along and south of
   a slowly southeastward progressing cold front.

   A few lightning strikes are possible within elevated convection off
   the southern CA coast. Vorticity maximum responsible for this
   convection will likely move onshore around 00Z Wednesday. A
   lightning strike or two is possible over San Luis Obispo and/or
   Santa Barbara counties but overall coverage is expected to remain
   too isolated to introduce a general thunderstorm area.
