~Summer Around the Pacific Northwest~
Exclusive Inland NW Summary Issued: Monday, September 14, 2026 @ 5:30am

(Summaries are issued as needed and will be updated more frequently during times of active weather)
SHORT-TERM FORECAST
The potent storm that moved through the Northwest over the weekend continues to move east, but some wrap-around cloud cover out of the Northwest will continue to slide over the region early in the period. Most locations will stay dry, but there is still a slight chance of a scattered light shower. Higher pressure will move in around midweek and persist into the upcoming weekend. Expect a warming trend, with temperatures expected to rise into the 70s, giving us some pleasant late summer-like weather. Even so, I can't totally rule out the chance of an isolated shower as weak disturbances continue to pass close to the forecast area at times, especially later in the week.
LONG-TERM FORECAST
The extended forecast isn't so cut and dry as some models are forecasting the high pressure ridge to be in a weakened state as the period progresses. As such, some storminess will once again pass close to the Northwest. If that occurs, it will lead to a renewed chance of showers and another cooling trend going into next week.
General Short-Term Model Agreement: GOOD
General Long-Term Model Agreement: GOOD
