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

...SUMMARY...
Isolated severe storms are possible across the Deep South into the
Tennessee Valley on Tuesday and Tuesday night.

...Synopsis...
A weak mid-level shortwave trough across the Tennessee Valley will
dampen through the period as it advances into the western Atlantic
after 00Z. A trough across the northern Plains will amplify through
the period as it advances into the Upper Midwest and develops a
closed upper low. A surface low will develop near Wisconsin/Lake
Michigan and deepen through the day and into Tuesday night. As it
deepens, a surface cold front will sharpen and accelerate east from
the Great Lakes to the Lower Mississippi Valley.

...Deep South...
A strong low-level jet will extend from northern MS/AL to southern
Ohio Tuesday morning and will quickly move northeast through the
day. This will result in weaker, more veered flow across the warm
sector during the afternoon. Rising heights in the wake of the
morning mid-level shortwave trough and weak convergence along the
front may mitigate severe storm potential during much of the day,
despite weak to moderate instability and moderate shear across much
of the uncapped warm sector. However, scattered storms, some which
could be strong, are expected along and ahead of the frontal zone
during the afternoon and early evening. Damaging wind gusts will be
the primary threat, but some isolated large hail may also occur
across portions of MS/AL where greater instability is forecast.

Overall, stronger forcing amid falling heights aloft and greater
convergence along the cold front, is anticipated Tuesday night.
However, weaker instability should mitigate the overall severe
weather threat. A few stronger storms are possible after 06Z across
the FL Panhandle into southeast Alabama and southwest Georgia where
upper 60s dewpoints off the Gulf should be sufficient for moderate
instability, even during the early morning hours. However, even if a
few supercells can form during this period, severe potential may be
somewhat limited given only modest mid-level lapse rates and weak
low-level flow.
