KEY MESSAGES

- Prolonged Quiet Weather Period: High pressure and dry air will keep eastern Idaho completely dry with minimal cloud cover through the upcoming weekend and into early October.

- Unseasonable Late-Week Warmth: An amplifying Great Basin ridge will boost lower-elevation temperatures into the upper 70s and lower 80s through the weekend.

- No Fall-Like Weather in Sight: High confidence exists for above-normal temperatures and suppressed precipitation extending through the first full week of October.

DISCUSSION

Issued at 114 AM MDT Sat Oct 3 2026

High pressure will remain in control of our weather pattern through late next week, meaning a continuation of warm and dry conditions. Temperatures will continue to run above climatological norms with peak warmth occurring on Sunday as the ridge amplifies over the region. Daytime temperatures on Sunday will run around 10 degrees above normal with valley locations warming into the low to mid-80s. High resolution models indicate a shortwave feature working through Monday and Monday night, along with very weak moisture signals working through the ridge. This could mean very slight chances for precipitation across southeast Idaho, although confidence remains low at this time. Otherwise, our next chance of precipitation looks to be next Saturday when the next trough works through.
