Day 1 Convective Outlook

Valid 261200Z - 271200Z

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

...SUMMARY...
Isolated severe thunderstorms with hail and strong wind gusts are
expected across parts of the Southeast on Thursday afternoon and
evening.

...Eastern Alabama/Georgia/South Carolina/Central North Carolina...
An upper-level trough will move across the Southeast today as a 55
to 65 kt mid-level jet moves through the base of the trough. At the
surface, a low will move from the central Gulf Coast States into
Georgia as a cold front advances eastward across the region. A
corridor of weak low-level moisture with surface dewpoints mostly in
the lower to mid 50s F will be in place ahead of the front by
afternoon. Surface heating and increasing low-level convergence near
the surface low should result in convective initiation across
central and northern Alabama around midday. Convective coverage is
expected to increase with thunderstorms moving across central and
northern Georgia and into South Carolina this afternoon. Storms
should eventually reach central North Carolina this evening. RAP
forecast soundings at 00Z from Atlanta, GA to Columbia, SC show
surface dewpoints in the mid 50s F, MLCAPE around 500 J/kg and 0-6
km shear of 35 to 45 kt. This may be enough for a few marginally
severe multicells. The primary threats should be for hail and strong
wind gusts.
