Exclusive Inland NW Summary Issued: Friday, September 11, 2026 @ 4:00pm

(Summaries are issued as needed and will be updated more frequently during times of active weather)
SHORT-TERM FORECAST
Cooler air will continue to filter into the forecast as an upper-level low makes headway into the Northwest. Models are coming into better alignment now in that the storm will track close enough to give much of the forecast area another round of significant beneficial rains. While there is a slight chance of a thunderstorm late Saturday, the main event will hold off until Saturday night, leading to a cool and rainy day on Sunday. Some additional thunderstorms are possible in places on Sunday, leading to locally heavier rainfall totals. Temperatures will remain on the cooler side of normal, especially on Sunday, and it will be breezy at times as well. Some models are forecasting the chance of scattered showers again on Monday and Tuesday, but that will all depend on how fast this latest storm moves out of the Northwest.
LONG-TERM FORECAST
There are strong indicators showing a return of higher pressure as the 3rd week of September progresses. This should bring with it drier, warmer weather around midweek, which should then continue into next weekend. In fact, temperatures are forecast to rise to above normal averages as we head toward the end of the workweek, with little chance of any measurable precipitation. This pattern would be more typical of September weather, and it may persist for several days!
General Short-Term Model Agreement: GOOD
