...NO SEVERE THUNDERSTORM AREAS FORECAST...

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

...Synopsis...

An upper trough will move across the eastern U.S., moving offshore
the Atlantic coast Sunday night. Meanwhile, broad upper troughing
will be maintained across much of the CONUS, reinforced by shortwave
impulses over the northern Rockies and Upper Midwest. At the
surface, a cold front will move southeast across the FL Peninsula
through the afternoon, while a second cold front moves southeast
across parts of the Midwest and Plains overnight.

A dearth of boundary layer moisture and a cold/stable airmass will
preclude thunderstorm activity across most of the CONUS. The
exception may be across portions of the southeast FL Peninsula and
the Keys. Modest boundary layer moisture will support weak buoyancy
near the coast and just offshore as the upper trough and surface
front provide forcing for ascent. A few lightning flashes are
possible, but the bulk of thunderstorm activity is expected to
remain offshore where better instability will support deeper
updrafts.
