Valid 221200Z - 231200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not expected on Tuesday.

....Synopsis...

A shortwave upper trough over the Lower MS Valley will weaken and
lift northeast, merging with another shortwave trough over the Great
Lakes/Midwest on Tuesday. Further west, an upper ridge over the
western U.S. will spread east over the northern Plains as an upper
shortwave trough develops east/southeast over the northern Rockies.
At the surface, high pressure will persist across much of the CONUS,
and northerly low-level flow over the South will keep Gulf moisture
will offshore, except across the FL Peninsula. Similar to prior
days, isolated to scattered thunderstorms will be possible across
the FL Peninsula and Keys. However, generally weak instability and
lack of stronger ascent will limit severe potential.
