...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS IN A PART OF THE
TN VALLEY TO THE FL PANHANDLE...

...SUMMARY...
A couple brief tornadoes and locally damaging winds are possible
across a part of the Southeast on Friday morning into the afternoon.

...Southeast...
The remnants of TC Francine are expected to decay in place near the
AR/TN/MO border vicinity on Friday, with greater weakening of
low-level winds relative to today. Still, the strongest lingering
belt of low-level southeasterlies should persist through Friday
morning into the afternoon to the east, centered on the TN Valley.
This should yield moderate SRH coincident with the northern extent
of weak surface-based instability from central AL/far western GA
northward into Middle TN. This corridor will likely be narrow at any
one time and steadily shift east through the day. A drier air mass
with veered low-level winds is expected to its west, and cooler
surface temps beneath pervasive cloudiness should occur to its
northeast. A couple brief tornadoes will be possible, mainly from
mid-morning into the afternoon.

Low-level winds will diminish with southern extent to the FL
Panhandle, but moderate mid-level southwesterlies should yield
adequate deep-layer shear for transient mid-level rotation. Modest
boundary-layer heating of a residual tropical air mass should occur
within a corridor ahead of an occluded surface front. Locally strong
gusts capable of sporadic tree damage remain possible.
