DISCUSSION

Issued at 1018 PM MDT Mon Sep 7 2026

Drier southwesterly flow will gradually transition to more zonal flow by Wednesday as high pressure builds into the Desert Southwest. As a result, generally clear skies and warming temperatures will be the story for the coming week. There is a low (<15%) chance for an isolated shower or thunderstorm over the San Juans and Divide each afternoon. Temperatures will run 5-10 degrees above normal through the rest of the work week, with potential to drop back to near normal values over the weekend. Guidance is hinting at a potential moisture return at that point, as a trough moves into the Pacific Northwest and pushes the high to the east. However, agreement on this solution is still somewhat poor, so stay tuned if you have plans this coming weekend. In the meantime, enjoy the pleasant late summer/early fall conditions.

Issued at 1140 PM MDT Mon Sep 7 2026

VFR conditions are forecast through the TAF period. Winds will primarily remain light and follow their usual diurnal patterns with periodic gusts up to 25 mph Tuesday afternoon. Isolated storms cannot be ruled out over the San Juans and along the Divide Tuesday afternoon, but confidence was too low to include at any of the terminals.
