...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms will not occur tonight.

...Discussion...
Early evening water vapor imagery shows a mid-level trough over the
eastern Pacific and this feature will move ashore tonight and reach
interior portions of CA/OR by early Monday morning.  A plume of
moisture from the eastern Pacific may contain a few embedded
thunderstorms within a rain shield over central coastal CA, and a
few flashes are possible with weak convection near the far northern
CA coast northward into western WA.  Elsewhere, tranquil conditions
will prevail over a large part of the contiguous U.S.
