After a relatively dry last week, a much wetter pattern is on the way, starting on Saturday. Below is the expected rain total by 11 PM Tuesday from the European model.

Expect totals of 1-2.5 inches across the lowlands by late Tuesday. The coast and mountains will receive 3-6 inches of rain. Most of Eastern Washington will receive 0.4-1” of rain, substantial and necessary for that region.

Snow levels will hover between 2,500 and 4,000 feet, bringing a mix of rain and snow to the passes. Below is the European model’s snow forecast through 11 PM Tuesday.

Snow amounts at the passes is difficult to tell due to the marginal snow levels, but expect multiple feet at 5,000+ ft. elevation.

Breezy conditions are also possible late Saturday through Sunday, with gusts of 25-40 mph possible in the lowlands. The strongest winds will be on the Oregon Coast, due to a landfalling low pressure center, seen below on the UW model at 12 AM Sunday, as it is just offshore.

Expect winds gusting 50-60 mph from approximately Tillamook southward, and gusts of 40-50 mph on the southern WA coast and northern OR coast. Winds from this small low center will peak from midday Saturday to early Sunday morning.

This wet and generally active pattern is expected to continue, so stay tuned!
