Valid 271200Z - 281200Z

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

....SUMMARY...
Severe thunderstorms are not forecast for Sunday.

....Southeast/Mid-Atlantic Vicinity...

A compact upper trough/low over the Mid-MS Valley Sunday morning
will shift northeast toward the Canadian Maritimes by late Sunday
night. Strong southwesterly deep-layer flow will overspread much of
the eastern U.S. At the surface, low pressure over MO/IL will deepen
modestly while developing northeast toward the lower Great Lakes and
the St. Lawrence Valley. A cold front attendant to the low will
migrate eastward across the Southeast and Mid-Atlantic, moving
offshore by Monday morning.

Showers and thunderstorms will be ongoing Sunday morning in the
vicinity of the cold front across southeast AL and the FL Panhandle.
A couple of strong storms are possible the first couple hours of the
forecast period, but overall severe potential is expected to rapidly
wane with time during the morning and with eastward extent. Further
east, warm advection across GA into the eastern Carolinas/southeast
VA vicinity will result increasing low-level moisture ahead of the
front. While surface dewpoints will climb into the 60s F,
destabilization will be limited by widespread cloud cover and poor
low/mid-level lapse rates. While strong vertical shear will
overspread the region, overall severe potential is expected to
remain low, given poor instability and large-scale ascent shifting
increasingly northeast of the area.
