Stevens Pass
Mountain Weather Forecast
Day and Time: Monday 0630
Current Observations:
24hr Precipitation: 1” of snow
Temperature profile: 18base, 12ridge
Pass level winds: light
Barometer:1007mb’s and falling
Sky: OC
Radar: light snow is falling in the southern Columbia basin with the northern
portion of the state being cloudy and dry.
The Forecast: Clearing with cold temperatures and gusty
winds will move in today.
Long
Range: This stretch of cold, dry weather will finish out the
month and likely bring us into March.
The Science:
A long stretch of snow, extending from Portland Oregon to Bismarck North Dakota
will drift southeast over the next 24hrs. This is the source of the full-on blizzard that
the Midwest is bracing for.
As the low pressure system
drags south, the counter clockwise rotation will pull in a cold, dry air mass from
the intermountain west. This dry air mass
will settle over the PNW for the next 5-7days with little moisture available. Strengthening East/offshore
pressure gradients will also produce moderate to strong Pass level winds today.
Forecast confidence: Good.
Values from 4am today through
4am tomorrow.
