Time and Day: 0700
Saturday
The Snapshot: Increasing clouds today with light rain reaching Stevens Pass by mid-afternoon or so. Cooler tonight with mixed rain and snow showers tomorrow.
The Science: It’s a balmy 400f this morning with high clouds moving in. Moisture ahead of an approaching cold front will
bring light rain to Stevens Pass this afternoon with freezing levels +- 7000’. Once the front passes east of the crest,
freezing levels will drop to around 4500’ with light snow possible overnight. A weak ridge
forms behind the front which will produce some partial clearing tomorrow
morning with mixed rain and snow showers re-developing through the day.
The Long Range: A
steady stream of precipitation takes aim at the PNW next week.
