MOUNTAIN WEATHER FORECAST


Stevens Pass Mountain Weather Forecast

Day and Time: Wednesday, 1:00 pm

The Snapshot:  Dry today and tomorrow with a now decreasing chance of rain on Friday. The weekend will trend dry with daytime temperatures peaking in the upper 40’s or even lower 50’s.   

Current Observations: .10” of water with 1-3” of snow fell overnight.  The temperature is 31f, and the winds are light and out of the east. The barometer is currently 1015mb’s and on the rise. There is a thin layer of clouds currently over the Pass.     

The Science: The atmosphere will stabilize and dry out as the barometric pressure increases today.  A thin, mid-level stratus cloud deck has moved in which will insulate and thus slow down the snow melting process for the remainder of the day.  Some weak disturbance riding up and over the offshore high pressure will continue to bring in mixed layers of clouds today and tomorrow.    

The Forecast:  The winds will be light and easterly today with temperatures peaking in the lower 40’s.  Hit repeat for tomorrow.  Models now have Friday’s system tracking south of Stevens Pass, so the chance of wetting rain on Friday is decreasing.  Most of the snow will likely be melted off by tomorrow.

The Long Range:  The high pressure system dominating the offshore weather will bring mostly dry weather to the PNW over the weekend.  Next week looks like a mixed bag of rain/snow showers and clear periods – fairly typical weather pattern for this time of year.
