....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorm activity is not expected on Saturday.

....Synopsis...

Expansive surface high pressure from the Rockies through the eastern
U.S. will maintain a dry/stable airmass across most of the country.
Across the Pacific Northwest, an upper trough will move inland and
into the northern Rockies. A couple of thunderstorms offshore may
approach the Oregon coast Saturday morning in the moist onshore flow
regime. However, forecast soundings show weak instability which
rapidly decreases away from the coast. As such, thunderstorm
activity is expected to remain offshore.
