Valid 211200Z - 221200Z

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

....SUMMARY...
Severe thunderstorms are not forecast on Wednesday across the
contiguous United States.

....Synopsis...
A low-amplitude mid-level disturbance to the east of the GA coast
and over the FL Peninsula will move east into the western Atlantic
by midday.  A surface boundary will meander over the southern part
of the FL Peninsula during the day before advancing northward after
dark.  A few showers and isolated thunderstorms are possible over
the southern half of the FL Peninsula mainly during the morning.

Elsewhere, a powerful upper jet will quickly move southeast from the
interior parts of the Pacific Northwest and nose into the southern
Great Plains late.  An arctic front will surge southeastward from
the northern High Plains southeast into the middle MS Valley and
southern Great Plains.  Large-scale ascent will begin to strengthen
over the southern Appalachians late overnight as showers become more
prevalent.  A stray elevated thunderstorm cannot be ruled out in
Upstate SC.
