MOUNTAIN WEATHER FORECAST


Stevens Pass Mountain Weather Forecast
Day and Time: Monday 0600

Current Observations:
24hr Precipitation: .15swe, 2”of snow fell since yesterday afternoon
Temperature profile: 17f base, 16f ridge
Pass level winds: light and out of the east
Barometer: has risen to 1023mb’s 
Sky:  partly cloudy with clearing
Radar: dry conditions state wide

The Forecast:  The sun will make its last appearance of the year today.  Cold temperatures are moving in with dry weather expected through Wednesday.

Long Range: Enjoy the next two days because another wet warm system (similar to this past weekend) is taking shape.  Snow begins late Wednesday night with rain and wind anticipated on Thursday.   
  
The Science: The barometric pressure hitting 1023mbs is indicative of the high pressure ridge moving into the region.  Thus the skies are clearing and the atmosphere is drying and stabilizing.  Enjoy.  

The cold, dry air that has moved in from the interior west won’t stick around for long as warmer SW flow begins to make a push.  Wednesday/Thursday’s developing storm has very similar characteristics as this past event.   The winds don’t looks as strong but they will be in play.  Details are still developing, so for now, expect snow Wednesday night changing to rain on Thursday and then back to snow on Friday. 

Confidence in this event is fair to good.
