...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are unlikely through early Sunday morning.

...Discussion...
Cyclonic flow aloft is forecast to expand eastward across much of
the western U.S. though the period, as embedded short-wave troughs
south of the weakening low near the Vancouver Island vicinity eject
eastward. As these smaller-scale disturbances shift eastward,
ascent -- aided by westerly upslope flow -- will support convection
and occasional lightning, particularly along windward-facing slopes
across an increasingly broad area of the western states.

Meanwhile, a southern-stream short-wave trough will cross the
Southeast today and tonight. While lightning is ongoing over the
Gulf of Mexico and off the southern Atlantic Coast over the Gulf
Stream, occasional inland lightning will also be possible.

In all areas, severe weather is not expected, with convection
expected to remain weak and disorganized.
