Warm and mostly dry today and tomorrow ahead of a strong cold front late tomorrow night with scattered showers, isolated thunderstorms, high elevation snow, and gusty westerly winds.
Breezy and much cooler Sunday, with lingering showers in northeast OR and the central ID mountains.
Unsettled cool conditions through next Wednesday, then a warming and drying trend likely for the end of the week.
Issued 305 AM MDT FRI SEP 11 2026 Breezy westerly winds will linger over higher terrain this morning as a weak cold front continues tracking east. A short lived ridge of high pressure will build in later today into early Saturday, bringing temperatures about 3-5 degrees above normal for the region. Then, a strong low pressure system will move into the Pacific Northwest late Saturday with a strong cold front moving into southeast OR overnight. This front will then track into southwest ID by early Sunday morning. Southwest winds with gusts up to 40 mph, scattered showers, isolated thunderstorms, and much cooler temperatures will accompany this front. Current model runs track the low pressure and the bulk of the moisture into northern Idaho, keeping the best chances of precipitation over northern zones near Baker County, OR and Valley County, ID. Liquid equivalent precipitation amounts by Sunday will range from 0.50-0.80 inches, with snow levels dipping down to 6,500-7,500 feet above sea level by Sunday night. Snowfall accumulations will likely be around 1-2 inches over high terrain.
Issued 305 AM MDT FRI SEP 11 2026 Low pressure will gradually move east early next week, but continued troughing will linger over the region, keeping temperatures slightly below normal on Monday and Tuesday. Another weak low pressure system will move in by Wednesday, bringing a low chance of precipitation over high terrain and another brief cool down. Model disagreement then increases with the evolution of that low; however, the majority of solutions favor ridging returning by late week, with dry conditions and temperatures 5-10 degrees above normal expected.
