Weather Synopsis for Sunday night through Tuesday
A cold trough approaches the Pacific Northwest as it slides down the British Columbia coastline from the NW. A SW-NE-oriented cold front is draped from SW Washington across the central Puget Sound to around Mt Baker as of 2 PM. Moderate to heavy rain and snow pushes to the SE of the front, in a wide swath extending down to Mt Hood. Snow levels remain on the mild side ahead of the front with 3500-4500 ft snow levels in the Washington Cascades and 5500 ft snow levels around Mt Hood.
The front progresses rapidly SE through the evening hours, with plummeting temperatures for the mountains of Washington State as the more continuous precipitation shifts to moderate snow showers and heavier convergence bands focus on the central Washington Cascades. Mt Hood and the southern Washington Volcanoes should also pick up heavy snowfall with around 1" of snow water equivalent expected in the aforementioned areas.
Lighter to moderate snow showers and convergence continue as W winds shift a bit more to the WNW, focusing some of the convergence southward toward Snoqualmie. Snow levels remain below 1000 ft in most areas. Ridgeline winds become mostly light in the north, but remain in the moderate range in the southern half of the forecast region, potentially picking up a bit in the afternoon with a passing disturbance.
NW flow aloft develops Monday night through Tuesday. Mostly light snow showers (moderate in convergence) decrease into Tuesday morning. However, an approaching warm front will bring increasing mostly light, but potentially moderate snow into the region during the afternoon. Snow levels remain below 1000 ft.
