Weather Synopsis for Sunday night through Tuesday
Remnant post-frontal rain and snow showers continue for the Cascades Sunday evening, mostly ending overnight. Winds gradually shift SWerly ahead of the next system.
An active weather pattern develops at the beginning of the work week. A moisture-laden frontal system flattens a broad offshore ridge and toward our region from the WNW. As a warm front approaches on Monday, light to moderate rain and snow increase gradually spread throughout the mountains of Washington State. The Western Olympics, Mt Baker, and the Mountain Loop stand to pick up the most moisture (in the 0.25" - 0.5" of snow water equivalent range). Snow levels rise to 3500-4500 ft by the afternoon.
The warm front transits the region Monday night with moderate to heavy rain, snow and peak snow levels in the 4000-5500 ft range (lower in the north). Light to moderate rain and snow should spill over onto the east slopes of the Cascades and Mt Hood.
Expect decreasing light to moderate rain and snow on Tuesday as a cold front brings slightly cooler and drier air into the region from the northwest. Snow levels should drop to 3500-4500 ft.

LT = less than; WE or Water equivalent is the liquid water equivalent of melted snow in hundredths of inches. As a rough approximation 1 inch of snow = about .10 inches WE, or 10 inches of snow = about 1 inch WE.
