Time and Day: 0730 Saturday
The Snapshot: Lightly snowing with 1” of fresh snow this
morning. We can look forward to
intermittent snow showers and sun breaks for the remainder of the
weekend. Dry
and clear weather begins on Monday.
The Science: Satellite imagery has scattered snow showers rotating
around an offshore stationary low. Bands of moisture will continue to move north
as the low-pressure cell slowly drifts
southeast into Oregon over the next few days. The bulk of the moistures is
expected to remain along the eastern slopes with more accumulation east of the
Cascade Crest possible.
Freezing levels to
the east have settled around 2500’ with
3500’over the western slopes; this will continue to produce east-west pressure gradients and thus, periods
of gusty easterly winds.
The Long Range: Dry and clear weather develops on Monday as
high pressure strengthens over the PNW. The blocking ridge of high pressure is
expected to dominate the weather pattern for all of next week.
