DISCUSSION

Issued at 1237 PM MDT Mon Sep 7 2026

PWATs will continue to lower across the region today which explains why models are showing hardly any precip across the area. Daytime heating may allow a very isolated shower, maybe a quick storm, over the San Juans and the Continental Divide over the coming days but widespread coverage will not occur. Plenty of sunny skies will be the rule as temperatures run about 5 to 10 degrees above more seasonal norms. The next chance for more widespread precip looks to be the end of the week, heading into the weekend. Another monsoonal push of moisture may occur which will bring a return to more isolated to scattered convection. This far out though, confidence remains low.
