Exclusive Inland NW Summary Issued: Friday, September 25, 2026 @ 6:45am
WRITTEN BY: Climatologist Bob Lutz
(Summaries are issued as needed and will be updated more frequently during times of active weather)
SHORT-TERM FORECAST
A vigorous cold front will work its way across the Inland Northwest today, bringing with it gusty winds, showers, scattered thunderstorms, and much cooler temperatures. Some of the showers could be locally heavy, especially during any thunderstorm activity. Breezy and cool weather will follow over the weekend, with any lingering rain or snow showers confined to the higher mountains. In areas of calm winds and a clear sky, expect widespread frost during the overnight hours in the sheltered northern valleys through early next week.
LONG-TERM FORECAST
Near average temperatures will close out September and continue into the first few days of October. While there may be a passing shower, most locations will remain dry, as there are no organized storms expected during this period. In fact, there are some indications of more high pressure, which would result in another spell of dry weather and above normal temperatures going through early October.
General Short-Term Model Agreement: GOOD
