There is a threat of lowland snow showers across Western Washington Sunday and Monday as a cool and moist weather system tracks over the region. Snow levels will be close to sea level.
Given the showery nature of this system, snow amounts will not be uniform across the region. However, heavy accumulations are possible with stronger showers. Showers may decrease in coverage on Monday as this system exits south of the area.
Expect cool temperatures Monday through Wednesday with highs only in the 30s and lows in the teens to 20s. This is around 10 to 15 degrees cooler than normal.
