...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
A few thunderstorms are possible across the Pacific Northwest.

...Pacific Northwest...

Exit region of a strong mid-level speed max is translating onshore
across Coastal OR/northern CA. Large-scale forcing for ascent will
spread inland later tonight and thermodynamic profiles should become
increasingly favorable for at least weak convection along/ahead of a
cold front. Latest satellite/lightning data suggest a few
thunderstorms are noted about 150mi west of the northern CA Coast.
This activity should approach the northern CA coast after 06z, and
some threat for a few lightning flashes will be noted through
sunrise Saturday morning.
