The upper flow is set to change to the northeast late this afternoon. Cold arctic area will begin to make it's way south through the week. Tuesday a pacific frontal wave heads for the Washington coast in combination with a trough to the north brings a few clouds to the area. Snow arrives with the front early Wednesday. This is more likely in Vancouver as anything coming in probably won't make it up here.
Towards the end of the week the deep freze continues and intensifies through Friday.
We received 75cm this week and the snow should be nice and dry today in the alpine. Freezing levels breifly spiked at 1400m through the storm Friday.
