Time and Day: 0630 Saturday
The Snapshot: Light snow ending today, clear and warming
Sunday.
Current Observations: It’s
currently snowing lightly with strong, gusty winds. Temperatures are 30 in the
base area and mid 20’s on the upper mountain. There was a freezing rain event
last night that has capped most of our new snow from yesterday. RH is 90% and
the barometer is rising.
The Science: A low pressure trough moved
through yesterday afternoon/evening, dragging with it a warm upper level
air-mass. Stevens Pass dodged the bullet for a while, but freezing rain
accumulated between about 5pm and 8pm yesterday. In the trough’s wake this
morning we have gusty (40-50mph) westerly winds with light snowfall. Strong
west winds continuing for the next few hours should support orographic snow
showers this morning, which will become light and end completely midday. High
pressure builds in tonight and Sunday.
The Long Range: The high pressure ridge will build in strength and be
in place for the start of the new year, with freezing levels around 6-8k’
Monday and Tuesday.

Bummer that the warm front that was stalled to the south of Stevens all day yesterday decided to push north late last night. As Dan stated above, we are heading into a dry and relatively warm stretch. Watch for east west inversion condition to set up over the next few days. Happy New Year.
