...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE SOUTHEAST...

...SUMMARY...
There is a marginal risk of severe thunderstorms across portions of
the Southeast on Friday.

...Synopsis...
A mid-level trough will de-amplify as it moves into the Canadian
Prairies on Friday. At the surface, a cold front will move across
the northern/central Plains. The remnants of Hurricane Francine will
likely be extratropical and vertically stacked, somewhere near
eastern Arkansas Friday morning. This system will slowly drift east
through the day Friday.

...Southeast...
A belt of stronger mid-level flow will be persistent south and
southeast of a mid-level closed-low in the Tennessee Valley which
will overspread moderate shear across a moist and moderately
unstable surface airmass across eastern Alabama and western Georgia.
850mb flow will be quite weak and thus, low-level shear and the
tornado threat will likely be somewhat limited. However, 1500 to
2000 J/kg MLCAPE and effective shear of 30 to 40 knots will support
isolated stronger storms capable of damaging wind gusts.

...Central and Northern High Plains...
Some forced convection may develop along a cold front as it moves
through the northern Plains on Friday. However, limited moisture and
instability should mitigate the severe weather threat with this
activity.
