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

....SUMMARY...
Scattered storms, including potential for a few severe storms, are
forecast over parts of the central Gulf Coast states on Friday.

....Synopsis and Discussion...
On Friday, a moderately strong southwest flow regime will persist
from the southern Plains to the OH Valley, with another shortwave
trough moving across TX and OK during the day. This wave will have
little if any instability to interact as it will arrive only a day
after the OH Valley trough went through.

At the surface, a front will be near the TX Coast, extending
northeastward as a warm front across parts of LA/MS/AL during the
day.

Scattered storms may be ongoing across LA and MS and AL early in the
day, with increasing chances in the MS/AL area in association with
the warm front and with the air of heating. Uncertainty exists as to
the extend of destabilization, but 50 kt deep-layer effective shear
as well as 30-40 kt mean boundary-layer winds will conditionally
favor a few damaging gusts, especially where pockets of heating can
occur. Low-level shear will likely be maximized over parts of AL and
points northeast, with perhaps an overlapping area of supercell
potential. However, potential for a cooler air mass where low-level
shear is strongest precludes higher probabilities at this time.
