MOUNTAIN WEATHER FORECAST

Stevens Pass Mountain Weather Forecast

Day and Time:  Tuesday 0630

Current Observations:

24hr Precipitation: 0

Temperature profile: 25base, 19ridges

Pass level winds: light to moderate and out of the east

Barometer: 1019mbs and beginning to fall

Sky: Mostly clear

Radar: Clear

The Forecast: We will have to endure a few more days of this dry clear and relatively warm weather.

Long Range:  Dropping freezing levels and snow arrives late Thursday night for a snow day on Friday.

  

The Science:  The high pressure that has brought us this spring like weather is weakening, but will continue to dominate through Thursday.  The general flow will shift southerly over the next 24hrs.  This will erode the cool air trapped in the easterly basin and push freezing levels up to the 6-7000’ tomorrow and Thursday.

A strong cold front, developing in the Gulf of Alaska, will charge through late Thursday night.  This will drop freezing levels and provide some nice snowfall for Friday.   

Confidence in the timing and swe amounts is still fair but is improving with each model run.   

Values from 4am today through

 4am tomorrow.
