Cold, quiet weather will continue through the week. Expect valley inversions, with some degradation of air quality at times. A few snow showers are possible this weekend, but no larger storms are expected. -Jeff
An unsettled, much cooler Thursday is on the way, with showers a light, high-elevation snow. After a chilly start on Friday, warmer weather is coming for the first weekend of autumn. Next week looks unsettled again, with storms crashing into the Pacific Northwest. -Jeff
