...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms will be possible on Saturday over portions of
the Southeast, and near the northern California Coast.

...Discussion...
Fast/generally westerly flow aloft is expected across most of the
U.S. on Saturday, with a tight height gradient between ridging over
the Gulf of Mexico, and a polar trough across central and eastern
Canada and the Great Lakes region.  A short-wave trough, embedded in
this fast flow field, will sweep across the northeastern U.S.
through the period.  Farther west, a low is forecast to linger just
off the Oregon/northern California coastal area through the period.

At the surface, a cold front should stretch from a James Bay low
southward to Lake Erie and then southwestward into Texas at the
start of the period.  This front will move quickly eastward,
clearing the Eastern Seaboard by early evening, while moving more
slowly southward across Florida and the Gulf of Mexico through early
Sunday.  High pressure will prevail across most of the country, in
the wake of this front.

Showers -- and a few/embedded thunderstorms -- will likely accompany
the passage of this front across the East Coast and Southeast
states.  Showers and possibly a few lightning flashes will also
accompany the eastern Pacific low, possibly spreading into Coastal
areas of northern California and Oregon, particularly later in the
period.
