...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
The potential for thunderstorms appears low across the United States
Friday.

...Discussion...
Between a trough building along the West Coast and a weak ridge
stretching from Baja California to the Ohio Valley, enhanced
southwesterly mid-level flow will persist from California to the
Midwest. In turn, a relatively progressive pattern will continue,
especially across northern portions of the country. Farther south, a
pair of weak impulses will partially phase over the central Gulf
Coast Friday night.

Across the country, thunderstorm chances appear fairly low through
the period. A couple lightning strikes may be possible across the
northern California coast, owing to cold temperatures aloft.
However, decreasing boundary-layer moisture will limit buoyancy,
relative to the previous day, likely tempering thunderstorm
activity. Along the western/central Gulf Coast, weak forcing for
ascent will continue to yield pockets of elevated buoyancy Friday.
However, similar to the previous period, forecast buoyancy profiles
appear too thin/weak to support sustained deep convection.
