MOUNTAIN WEATHER FORECAST

Time and Day: 1030 Wednesday

The Snapshot:  Light snow showers today with another big weather event tomorrow.

The Science:  Intermittent snow showers and cooler air filled in behind the cold front that passed east of the crest earlier this morning.  Today will be in-between systems with snow showers from time to time. 

Another strong warm front will bring heavy precipitation back to the resort tomorrow.  This event will have a bit more moisture and higher freezing levels.   Heavy snow is expected to start mid-to-late afternoon and then switch to rain sometime tomorrow night.  5000’ freezing levels peak around midnight and then fall to 4000’ on Friday. 

The Long Range:   Friday will be a quiet weather day with some sun breaks and mild temperatures.   Another system tracking up from the southwest will bring another round of rain/snow mix to Stevens Pass on Saturday.  Rain will likely start the new week with freezing level possibly reaching 7-8K.

Today 24hr water = .25+ snow = 2-5
