KEY MESSAGES

- Morning fog is possible in the valleys, especially in the usual places (Uinta Basin, Hayden, Gunnison) and across the southern areas where so much rain fell. Look for any fog to burn off by about 9 AM. - Expect warm temperatures about five degrees above normal, and drier conditions through the weekend and the coming work week.

DISCUSSION

Issued at 916 PM MST Fri Nov 6 2026

Models are in good agreement with each other and with satellite imagery showing the cut off low descending over southwestern Arizona into northern Mexico where it will turn to the east Saturday to eject into Texas by Monday before turning to the northeast. For eastern Utah and Western Colorado, we'll see a ridge building east off the Pacific through the weekend bringing a weak northerly flow aloft keeping skies mostly clear with only high thin clouds. With all the surface moisture available, can't rule out a light afternoon shower on the higher terrain, but no significant accumulations are likely. With the moist ground and clear skies, fog may develop in the valleys overnight into the morning hours as about the only weather phenomenon, burning off by about 9 AM. This ridge develops into a high in the great Basin by about mid next week, but models are diverging by mid week on timing and track of the passing systems. The general consensus is another cut off low passing to the south along the Mexican Border about mid week undercutting the ridge, and a deep trough and low digging south along the West Coast next weekend to push the high/ridge east out onto the Plains. For the most part, we will see mild, dry weather for the coming week with generally light breezes and daytime temperatures running about five degrees above normal. It looks like this week will be a good time to finish getting your yard and things ready for winter, because winter is coming (that's not a forecast, just a fact).

AVIATION /12Z TAFS THROUGH 12Z SUNDAY/

Issued at 416 AM MST Sat Nov 7 2026

Winds will be light and terrain-driven throughout the next 24 hours. There is a low probability of patchy stratus and/or fog developing over ASE, EGE, or HDN this morning, though this probability is too low to include either in TAF's. Thus, VFR conditions are expected region-wide throughout the TAF period.
