Exclusive Inland NW Summary Issued: Sunday, September 20, 2026 @ 11:45am

(Summaries are issued as needed and will be updated more frequently during times of active weather)
SHORT-TERM FORECAST
A strong high pressure ridge will continue to generate unseasonably warm temperatures and dry conditions through at least the early portion of the new work week. As we move toward the end of the week, the ridge will begin to weaken, which will allow for cooler temperatures and a greater chance for some shower activity as storms off the eastern Pacific begin to enter the Northwest.
LONG-TERM FORECAST
Next weekend and the final days of September in the week thereafter are looking considerably cooler. There will still be the chance of a passing shower, but most of the more significant precipitation should be confined to the mountains. Having said that, it does appear that we will certainly be entering a more active fall pattern, so the precipitation side of the forecast is definitely subject to change!
General Short-Term Model Agreement: EXCELLENT
General Long-Term Model Agreement: GOOD
