LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/

Issued at 1200 AM MDT Sat Sep 12 2026

An overall pattern shift is expected for next week as models continue to see a decent upper-level trough push through the Pacific Northwest and into the Northern Rocky Mountains. While this trough is not expected to dig too far south during its passage, it will force the upper-level high to finally retreat further east and open a majority of Colorado to southwesterly flow and more monsoonal moisture. For Monday, present model agreement continues to see a weak cold frontal passage make its way south and across Colorado. Present runs of the models are still a little back and forth on the exact timing of the front entering Southern Colorado. However, present trends do see this front opening us up for better opportunities for showers and thunderstorms to develop across the plains and the I-25 for the day. These increase chances of seeing showers and thunderstorms look to hold through the rest of the week as models see another upper-level trough build just off the West Coast and keep Southern Colorado open to moisture and short-wave activity. Currently our best chances continue to trend for Tuesday and Wednesday night into Thursday with areas around the I-25 corridor and eastern plains seeing chances around 40 to 60 percent. Unfortunately these chances will also come with increase risk of flash flooding on present burn scars in our area. Still, this extra activity alongside some timely frontal passage Monday and Wednesday will see cool temperatures for the week, with present afternoon highs in the valleys and plains holding in the upper 70s to mid 80s starting Tuesday.
