MOUNTAIN WEATHER FORECAST

Stevens Pass Mountain Weather Forecast

Day and Time: Thursday 0900

The Snapshot:  It is good to see the sun, eh?  Clear and dry spring-like weather will be on tap through tomorrow.  Fresh snow will start the day on Saturday with the sun and dry conditions returning for the final day of the season.   

The Science

Current Observations:  It is a beautiful clear morning here at Stevens Pass with the temperatures on the upper mountain already reaching into the 40^0’s . The barometer is 1019mb’s and rising.  The satellite image has sunshine and dry conditions throughout the PNW. 

The Forecast:   This ridge of high pressure over the region will keep the sky clear and dry through tomorrow.  The ridge is expected to flatten and drift south tomorrow which will open the door for a weak system to track in on Saturday morning with snow. 

A cold front with cool NW air to tow will produce one more shot of snow for the season.  This system is fairly weak with a high pressure ridge hot on it heals. We should see a few inches of snow by noon or so with drying starting Saturday afternoon.

The Long Range:   High pressure rebounds on Sunday for a partly sunny and dry end to the season.
