We saw the coldest temperatures of the season over the past week along with some snow for the West Coast. Some of the valleys in the Sierra dropped down near 30 below zero on Saturday night.
The really cold air is a thing of the past and we may not see temperatures like that again until next Winter. Highs have returned to their seasonal averages in the low 40's. That is softening up the snow in the afternoons and making for beautiful skiing weather.
The large ridge of high pressure parked along the West Coast is going to stick around for another week. We will see a carbon copy of the weather every day through next Tuesday with sunshine and highs in the low 40's for the mountains.
By the middle of next week and beyond we begin to undergo some pattern changes. The ridge along the West Coast will begin to retrograde back away from the coast. At first it looks like most of the precipitation will be focused in British Columbia and then down into the Cascades.
The first system to bring a return of snow to the Cascades will be next Wednesday, and may even dip far enough South to dust the Northern Sierra Nevada.
Going into the last week of the month we may see the storm door continue to open. The storm track may begin to shift South down the coast eventually spreading some love down into California.
