...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected across the Lower 48 on Friday.

...Synopsis...

A broad upper trough will envelop much of the eastern half of the
CONUS on Friday. Meanwhile, another upper trough will approach the
Pacific coast late in the period, while upper ridging persists over
the West. At the surface, high pressure will build over the central
U.S. and a cold front will develop well south into the Gulf of
Mexico and offshore the Atlantic coast.  This will result in a dry
continental airmass over much of the U.S. Isolated thunderstorms are
possible over warmer waters offshore from the FL east coast and the
Outer Banks. Any thunderstorms associated with the eastern Pacific
upper trough will remain well offshore as well. Given a dearth of
boundary-layer moisture and a stable airmass, inland thunderstorms
are not expected across the Lower 48 on Friday.
