....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Organized severe thunderstorms are not forecast through tonight
across the contiguous United States.

....Synopsis...
Water-vapor imagery early this evening shows a large-scale mid-level
trough over the eastern U.S., a ridge over the High Plains, and a
trough over the Sierra Nevada.  The mid-level trough over the East
will continue east into the western Atlantic waters off the Carolina
coast and into the Northeast by late tonight.  A thunderstorm band
near the Carolina coast will continue moving east into the shelf
waters this evening as a cold front sweeps through much of the
Southeast and Mid-Atlantic states.  Isolated thunderstorms are
possible early this evening along the coastal Carolinas before
drier/more stable air advects into the region.  Weak buoyancy
located near the immediate coast will likely hinder strong storm
development.  Farther north, a few thunderstorms are possible over
portions of the Northeast tonight.
