....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF THE SOUTHEAST AND CAROLINAS...

....SUMMARY...
Isolated strong to severe thunderstorms are possible on Wednesday
across portions of the Southeast and Carolinas.

....Southeast to the Mid-Atlantic...

An closed mid/upper low and attendant trough over central portions
of the U.S. will slowly shift east on Wednesday. Strong deep-layer
southwesterly flow will continue over the Southeast and northward
along the Eastern Seaboard. At the surface, a weak low will track
east/northeast across the Midwest and lower Great Lakes vicinity. A
trailing cold front also will shift east through the period, from
the Ohio Valley and Deep South to the Mid-Atlantic and Southeast
coast/northern FL.

Warm advection on southerly low-level flow will transport 60s
surface dewpoints northward across GA/SC/NC and southeast VA.
Widespread cloud cover and areas of ongoing precipitation will limit
destabilization, leading to only weak instability ahead of the
surface front. Higher instability will extend across the FL
Panhandle into GA and diminish with northward extent across the
eastern Carolinas. Nevertheless, strong deep-layer flow will support
moderate effective shear, leading to at least transient organized
convection. Isolated strong to severe storms capable of damaging
gusts, and perhaps a couple of tornadoes, will be possible through
Wednesday afternoon/early evening.
