Weather Synopsis for Sunday & Monday
The calendar may have turned to December but the next few days will not feel very winter-like. Upper level ridging extending from the southwestern US to our offshore waters will keep us dry through mid-week. Freezing levels will soar to 10,000-11,000' over the area today and more or less stay there for the next few days with mid/upper mountain temperatures above freezing and topping out in the 40s today. Expect a cooler start at lower trailheads and lower elevations until you pop out above the inversion. The east slopes of the Cascades near and north of Hwy2 will see a cooler start and slower warming trend today but will still see high freezing level/milder temperatures as the day wears on.
We can expect some high clouds over the north Cascades this morning to become patchier this afternoon with clearer skies further south. Low level cold air in the mountain valleys and light to moderate easterly offshore flow will allow some low clouds through the Cascade Passes. These low clouds should break up this afternoon and become patchier overnight. Low clouds and fog will likely be patchier near the Passes on Monday.
