KEY MESSAGES

- Weak Precipitation Chances Monday: A weak feature may bring isolated thunderstorms with very little precipitation to some higher elevation areas Monday.

- Unseasonable Late-Week Warmth: An amplifying Great Basin ridge will boost lower-elevation temperatures into the upper 70s and lower to mid 80s through the weekend. Some may see near record or record highs.

- Dry And Warm Through Friday: High confidence exists for above- normal temperatures and suppressed precipitation extending through the first full week of October.

DISCUSSION

Issued at 145 AM MDT Sun Oct 4 2026

High pressure will remain in control of our weather pattern the rest of the weekend and most of next week, meaning a continuation of warm and mostly dry conditions. Temperatures will continue to run above climatological norms with peak warmth occurring either today or Monday as the ridge amplifies over the region. Daytime temperatures during this timeframe will run around 10 to 15 degrees above normal with valley locations warming into the low to mid-80s. High resolution models indicate a shortwave feature working through Monday bringing with it isolated convection and very slight chances of precipitation. Otherwise, our next chance of precipitation looks to be next Saturday when the next trough works through. National Blend temperatures return to climatological norms next Saturday and drop more than 10 degrees below normal on Sunday.
