...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Organized severe thunderstorms are not forecast through early
Saturday morning across the Lower 48 states.

...Synopsis...
Upper troughs along the West Coast and near the TX Gulf Coast will
slowly push eastward during the evening/overnight.  The cool
mid-level temperatures associated with the aforementioned features
are yielding very weak buoyancy.  Weak low-topped convection,
capable of isolated lightning flashes, is possible over the Upper
Coast of Texas' shelf waters and the central California coast
vicinity.  Elsewhere, quiescent conditions will influence the
contiguous U.S.
