Stevens Pass Mountain Weather Forecast

Pass temperature:   31 degrees

Barometer:  Steady at 1029 mb’s

The Forecast: Sunny, warm, and clear today. Truly June-uary.

Long Range:  The enormous high pressure ridge will remain in place for the next several days, east flow should develop Sunday for typical inversion type conditions possible. The ridge begins to breakdown in the middle of next week, allowing a return to winter by the end of the week.

  

The Science: An obvious high pressure ridge is parked over the West coast, pushing any and all weather systems well north of us. The pressure gradient supports onshore flow today, so the sunny and warm temperatures should be felt at Stevens Pass today along with the rest of the state. East (offshore) flow looks to develop Sunday for potential pass level inversion conditions.
