First true cold air of the season on the way
A few scattered showers begin Saturday (Dec. 3rd) but the day should be mainly dry with some sunbreaks across the region and the state.
Expect gusty wind conditions at the Coast today. A High Surf Advisory remains in place until Noon today for big waves along the beaches. Never turn your back on the ocean!
Rain moves back into the Valley by tonight. Snow will start piling up again in the mountains with varying amounts depending on elevation. A Winter Weather Advisory has been issued for the Cascades of Oregon and Washington. It will kick in tonight, and last through Sunday afternoon. Expect snow at pass level and above through Sunday afternoon. Amounts will be anywhere from 6-15 inches. Higher amounts will be toward Timberline and above.
Colder air begins to pump in behind this system with a low pushing down the coast. Moisture will not cut off too much as snow levels begin to drop to around 1,000'. We're expecting higher elevations in SW Washington to see some flakes Sunday night. While another push of moisture early Monday is expected to create some snow for the Coast Range, higher elevations of Columbia County and Portland's West Hills. Other high spots around the Metro area like Council Crest and Mt. Scott may see some, too. While cold air stays in place through the morning, we could see some mixed precip. to the Valley floor. Warming afternoon temperatures, and the fact that this is our first "wintry blast" of the season will limit amounts and how long it all lasts.
Lingering showers Tuesday could give us a little more of a mix. Expect drier and colder conditions Wednesday. Thursday morning another bit of mixed precip. could show up, but otherwise we're expecting cold rain to finish out the week.
Today - Mostly cloudy, a few scattered showers - 51
