...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected tonight.

...Discussion...
Along the northern periphery of an expansive upper ridge over the
West, several subtle/low-amplitude perturbations will overspread
northern CA and the Intermountain West tonight. While associated
cooling aloft amid a deep saturated profile will yield weak elevated
instability, any thunder potential will remain limited/isolated.
