Weather Synopsis for Sunday & Monday
A weak trough moved through the Cascades Saturday night. Scattered, generally light rain and snow showers continue along the west slopes of the Cascades. Shower activity could increase slightly in the afternoon. Spillover is expected to be limited to the immediate lee of the Cascade Crest on the east slopes of the Cascades. Expect partly cloudy skies or even full sunshine as you head further east. In most areas, temperatures started the day a few degrees warmer than on Saturday, with snow levels of 2500-3000 ft expected in the morning, rising around 3500 ft in the afternoon.
A broad ridge edges into the region Sunday night. Lingering rain and snow showers mostly taper for the west slopes of the Cascades during the evening hours, but clouds and some very light rain and snow move into northwest Washington Overnight as the next system approaches from the northwest.
Light rain and snow spread across the Olympics and into the Cascades Monday morning, becoming moderate for the west slopes of the Olympics, the mountain loop, and Mt Baker areas by the afternoon. Increasing moderate SSW winds associated with a modest barrier jet will also help wring out the rain around Mt Baker. Snow levels should start around 3000 ft, rising to 3500-4500 ft in the afternoon.
