STEVENS PASS MOUNTAIN WEATHER

4/11/2012 Weather

General Discussion: Radar shows a band of moisture drifting up the west slopes of the Cascades today. Cooler air will allow a chance of some snow on the upper mountain with a mix of rain and snow in the base area.

Long-term: This weather pattern of light passing showers with intermittent clearing looks like it will be with us for the next 6-10 days. A typical spring pattern in the Cascades I suppose.
