RAIN. A strong upper-level 'steering wind' continues to drive relatively warm, moisture laden air right into the PNW. Multiple inches of rain have already fallen across a large swath of the region. Flooding has been minimal because of the breaks in the steady rainfall. The heaviest rain remain on track to arrive between Friday and Monday afternoon. Anywhere from an additional 2-4 inches possible for western valley locations and upwards of 7-8 inches of rain in coastal mountains & western slopes of the Cascades is likely.

WIND. A few more 'waves' of surface systems will brush onshore over the weekend, two of which will generate strong wind fields as they move onshore: the first late Saturday, the second late Sunday, early Monday. The Sunday storm is progged to be one of the strongest of the fall/winter season for western Oregon. Potential for a 16-20 mb pressure difference between Eureka & Astoria early Monday morning would generate a significant wind event, even for inland valley locations. PLEASE be prepared for possible power outages. Soils will be like pudding; firs may fall.

DRY. After the Sun/Mon storm spins inland, conditions will rapidly dry out, with periods of warm sunshine and possible FOG (esp Wed morning). The dry, high pressure ridge pattern is likely to hold on through Valentine's Day weekend.
