....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
GEORGIA AND SOUTHERN SOUTH CAROLINA...

....SUMMARY...
A few strong/severe storms may affect portions of Georgia and
southern South Carolina Monday.

....Synopsis...
Large-scale upper ridging will prevail across the western and
central U.S. Monday, as a cool Canadian surface high settles
southward to encompass a large portion of the country.  At the
leading edge of this cooler continental air mass, a cold front will
shift southward across the southeastern states, as a mid-level
trough shifts southeastward out of the Appalachians across the East
Coast states, and eventually offshore.

Showers and thunderstorms are forecast across parts of the
south-central and southeastern U.S. near and ahead of the
southward-moving front, and in more isolated fashion across the
West.

....Georgia/South Carolina...
As a cold front advances southeastward across the Southeast,
enhanced northwesterly flow aloft will spread across parts of the
Southeast before shifting offshore.  As this occurs, a window of
opportunity for a few stronger storms appears to exist, as daytime
heating contributes to some destabilization just ahead of the front.
 If a cluster of storms can evolve, some damaging wind potential
could organize and shift southeastward across Georgia and southern
South Carolina during the afternoon, before weakening and eventually
moving offshore during the evening.
