...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected across the U.S. mainland
through tonight.

...20Z Update...
Have introduced a general thunderstorm area for what is anticipated
to be a low/isolated potential for thunderstorms the remainder of
the afternoon into evening across central/eastern South Carolina and
nearby small parts of Georgia/southeast North Carolina. Forcing for
ascent related to a southeastward-digging vort max and thermodynamic
profiles conducive for charge separation should allow for at least
isolated/episodic low-topped thunderstorms as convection spreads
east-southeastward through evening.

...Discussion...

Band of scattered showers and thunderstorms developing along a cold
front has moved off the southeast FL coast. Otherwise, a large area
of high pressure will maintain offshore flow and stable conditions
across the U.S. through the remainder of the period.
