...SUMMARY...
Thunderstorms are not forecast across the U.S. today through
tonight.

Another quiet convective day is forecast across the CONUS today,
with no thunderstorms anticipated. A deepening surface cyclone off
the Carolina/Georgia coast will aid in the development of
thunderstorms offshore, but that activity is not expected to affect
inland areas.
