Valid 121200Z - 131200Z

....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF THE TENNESSEE VALLEY AND THE SOUTHEAST...

....SUMMARY...
Scattered strong thunderstorms may impact parts of the Southeast on
Monday. The strongest activity may pose a risk for a couple of
tornadoes, locally strong surface gusts, and isolated hail.

....Southeast...

The mid/upper low over the lower MS Valley will pivot northeast
toward the TN Valley on Monday. A belt of enhanced
south/southwesterly flow aloft will overspread portions of the
Southeast. Vertically veering wind profiles, with 30-45 kt of flow
between 700-500 mb, will support effective shear magnitude greater
than 30 kt across much of the risk area. South/southeasterly
low-level flow will maintain a moist airmass. Meanwhile, cool
temperatures aloft will support modest midlevel lapse rates. Pockets
of stronger daytime heating with aid in modest destabilization, with
MLCAPE around 500-1000 J/kg forecast. Similar to the previous couple
of days, bands of cells/clusters are expected through the day. This
activity will pose an isolated risk for locally damaging gusts,
marginal hail, and a tornado or two.
