DISCUSSION

Issued at 846 PM MST Wed Nov 4 2026

DRIER WEATHER THROUGH THE WEEKEND:

Snow showers are expected in the central mountains until around sunrise. Travel in these areas may be impacted by snow and icy roads mainly at pass level. Lingering moisture and clearing skies could result in pockets of fog into Thursday morning. Otherwise conditions become relatively dry. A quick moving shortwave skirts the region on Friday which could bring some increased clouds and a few light rain or snow showers over the higher terrain. The moisture is rather limited and the system is quick, so expect minor rain and snow amounts for now. A broad ridge of high pressure moves in late this week into the coming weekend, with temperatures warming to above seasonable levels and providing a much needed break from the recent wet weather.

AVIATION /12Z TAFS THROUGH 12Z FRIDAY/

Issued at 420 AM MST Thu Nov 5 2026

Dense stratus has lowered cigs below ILS breakpoints at all western Colorado terminals (except DRO). Cigs are expected to improve between 14-18Z, and afternoon skies will be mostly clear. An additional concern this morning will be fog in valleys. Confidence is low on when, where, and if fog will develop, but with many terminals nearing saturation this morning, TEMPO groups for fog have been added to ASE, EGE, RIL, GJT, MTJ, GUC, HDN, and CNY. Should fog develop, it should begin to dissipate between 14-16Z. Once stratus and fog are gone, VFR conditions will prevail regionwide.

HYDROLOGY

Issued at 1118 AM MST Wed Nov 4 2026

Flooding concerns remain heightened across southwest Colorado and southeast Utah. While many rivers continue to recede and have fallen below minor flood and action stage, low lying areas are still saturated and some rivers and creeks still remain in minor to moderate flood stage. Locations further downstream will see delayed impacts with some having only recently crested and others yet to crest over the next 24 hours. The San Juan River through the Four Corners and towards Bluff and Mexican Hat still are expected to remain above flood stage through at least Thursday. Please continue to heed any remaining road closures. Visit water.noaa.gov for the latest river forecasts in your area.
