Stevens Pass Mountain Weather Forecast

Day and Time: 0900 Sunday

Pass temperature: 34

Winds:  5-10 W

Barometer:  1010mb’s and slowly rising

Radar: There are bands of moderate to heavy rain moving through the region. The radar shows pockets of mixed snow and rain falling along the Cascade Crest above 4500’ with snow in the higher (6500’) elevations.

The Forecast: Intermittent mixed snow and rain showers start the week with another round of heavy precipitation and high mountain snow expected for Wednesday.

Long Range: The storms keep rolling in through the rest of the week with warmer temperatures. November will start out like it should – wet.    

  

The Science:  A cold front moved east of the crest about an hour ago.  Bands of moisture and cooler air are filling in behind the front. Freezing levels will fall to +-4000’ this afternoon with mixed precipitation falling through the next 24hrs.  Winds have shifted westerly and will be gusty through the day as well.

The high pressure system off the California/Oregon coast with westerly flow over the PNW will keep the storms rolling in.  Warm air advection will accompany a warm front late Tuesday.  Thus, models have freezing levels rising to +7000’ Tuesday night with another round of heavy rain expected to greet the day on Wednesday.
