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 /06Z TAFS THROUGH 06Z FRIDAY/

Issued at 1015 PM MST Wed Nov 4 2026

Some light valley rain and mountain snow showers will continue mainly across central portions of western Colorado, slowly coming to an end by 12Z. Low CIGS will occur at mountain TAF sites and some valley locations where showers pass through but overall, anticipate VFR to MVFR conditions with IFR in any showers due to low cigs/vsby. Mountain obscurations are also likely overnight with clearing behind it from the west between after 12Z. Cannot rule out some low stratus/fog in some valley locales overnight after this system exits the region but confidence was too low to put in the TAF at this time. Some low stratus and fog may linger through sunrise with VFR conditions and a few clouds post sunrise through Thursday afternoon.

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.
