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

....SUMMARY...
Isolated thunderstorms will be possible across far south Florida on
Sunday, but no severe thunderstorms are expected.

....DISCUSSION...
An upper-level trough will move across the eastern U.S. on Sunday,
as a ridge moves through the south-central states. A shortwave
trough will move through the Desert Southwest. At the surface, an
area of high pressure will move northeastward across the
Mississippi, Tennessee and Ohio Valleys. A moist airmass will be in
place across south Florida on the southern periphery of this large
area of high pressure. Enough instability should be present in far
south Florida for thunderstorm development. However, any development
should remain isolated due to a lack of large-scale ascent, and the
instability and shear should be inadequate for a severe weather
threat. Elsewhere across the continental United States, no
thunderstorm development is forecast Sunday or Sunday night.
