STEVENS PASS MOUNTAIN WEATHER

11/1/2010 Weather


General Discussion:
The mountains will get a good dose of rain today due to a large SW fetch of moisture hitting the PNW. A dry aim mass will settle in tomorrow.

Long-term:
A large high pressure system covering the entire western part of the country will produce dry and relatively benign weather here in Washington for the remainder of the week. The next weather system will start to affect the Cascade Mountains on Friday.
