Stevens Pass
Mountain Weather Forecast
Day and Time: Wednesday 0700
Current Observations:
24hr Precipitation: .21swe, 4”
snow
Temperature profile: 25 base, 20 ridge
Pass level winds: Light westerly
Barometer: 1015mb’s and climbing
Sky: OC
Radar: there is a line of showers in the southern (Snoqualmie) convergence
zone with the rest of the state beginning to dry up.
The Forecast: A few light snow showers will be possible
this morning with dry and partly cloudy conditions expected for the rest of the
week.
Long
Range: Cool nights and warm days with little to no precipitation
will be the weather pattern through the weekend.
The Science:
With the convergence zone still active, I
wouldn’t rule out the possibility of another inch or two of snow this
morning. Although the radar has most of
the active to the south of Stevens Pass.
The mountains will enjoy
the first taste of spring as high pressure builds and strengthens over the
inland NW over the next 3-5 days. The moisture
will be confined to the coastal region with partly cloudy and dry weather expected
for the mountains. A diurnal temperature
pattern will develop for a potential melt-freeze cycle developing. A corn cycle perhaps? Daytime temperatures could peak near 500f
over the weekend.
Forecast confidence: Good – models are in fairly good agreement for
this upcoming weather pattern.
Values from 4am today through
4am tomorrow.
