DISCUSSION

Issued at 853 PM MST Mon Nov 2 2026

Isolated snow showers are possible in the mountains overnight with minor accumulations. Other than that most locations will be dry and that continues into tomorrow. Given so much moisture and limited sun today, patchy fog is certainly possible in the favorable spots tonight. Tomorrow will be partly cloudy with temperatures 5-10 degrees below normal. This break will be short lived, as another low pressure works across the region on Wednesday. While moisture remains unimpressive with this system, a few showers and thunderstorms are expected Wednesday afternoon and overnight. Given the saturated soil there is concern for any additional rainfall. As of now the precipitation amounts are minor in comparison to the last event. Although thunderstorms could produce the rates for localized issues. We will continue to monitor this situation. The mountains should pick up another couple inches of snow too before the precipitation comes to an end Thursday morning.

Models continue to sell broad high pressure building across the region to close out the week. This should help streamflows and soils to dry out. Temperatures will remain cooler than normal, but a slight warm up is expected this weekend ahead of a potential pattern shift early next week.

AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/

Issued at 401 AM MST Tue Nov 3 2026

Low stratus has brought cigs below ILS breakpoints for ASE, EGE, RIL, and HDN tonight. There is also a chance that patchy fog will develop near these terminals, as well as DRO and GUC, which could reduce vis to MVFR or IFR at times throughout the morning. Both cigs and vis should be improve by 16-18Z though, and VFR conditions will prevail throughout the afternoon.

HYDROLOGY

Issued at 853 PM MST Mon Nov 2 2026

Many rivers across southwest Colorado remain above flood stage. As these crests work downstream water levels will receded at some locations and rise at others. Most of the rivers in Colorado will be out of flood stage in the next 24 hours. All of this water will eventually move down the San Juan river in Utah. This portion of the river is expected to be above flood stage Wednesday and Thursday.
