STEVENS PASS MOUNTAIN WEATHER

12/24/2011 Weather

General Discussion: The moisture will lift north today for a relatively dry night. A cold front will bring snow to the mountains tomorrow. Timing will be everything whether or not we will see a little rain at the start. But is should be mostly snow through the meat of the day.

Long-term: A nice PNW storm cycle is underway so expect active weather to finish out the year. The freezing levels will be near Pass level for most of the approaching storms, so keep your fingers crossed.
