Last Map Update: Sun, Oct 11, 2026 at 4:56:20 pm PDT

A front moving in will bring strengthening north to northeast winds today. Gusts of 20-30 mph are expected, locally 35-45 mph around the Upper Columbia Basin, peaking in the afternoon. Possible impacts of blowing dust, airborne objects, travel difficulty and choppy lakes.
Blowing dust is in the forecast for Sunday from morning to late afternoon. Visibility may drop quickly along I-90 and other major travel routes across central Washington.
Colder air settling into the region will lead to some sub-freezing temperatures in areas that are still in the growing season. Monday Night and Tuesday morning (11 pm to 9 am) carries the best opportunity for freezing temperatures in the Okanogan Valley, Moses Lake Areas and L-C Valley. Take any precautions you may need to protect sensitive plants or crops.
