KEY MESSAGES

- Light snow will occur over the northern mountains and eastern Uintas today. Minimal accumulation expected.

- A stronger moisture push moves in tomorrow through Thursday bringing accumulating mountain snow. Winter weather highlights have been issued for the Flat Tops and northern and central mountains.

- Unsettled weather continues for the mountains through Friday, with a brief lull this weekend and additional precipitation possible early next week.

SHORT TERM /THROUGH WEDNESDAY NIGHT/

Issued at 136 PM MST Tue Feb 10 2026

A very weak and shallow wave is currently moving across the northern valleys and mountains. This wave is providing just enough lift to allow some showers to form with light snow being reported at Craig and Hayden while the Park Range is also seeing some light snow. This is just the precursor to the next stronger shortwave moving out ahead of an upper level low that is just now coming ashore in California. Flow around this low has tapped into moisture that will continue to stream into the area and as the wave moves through, widespread rain and snow showers are expected. This next batch of precip will start around daybreak Wednesday and continue through noon Thursday. There will be lulls in the precip from time to time and thanks to the southwesterly flow, most of the precip in the valleys will be rain. Snow levels will remain around 8.5k feet, give or take, so mountain passes can expect a tough time of it Wednesday and Thursday. That being said, snowfall amounts remain in the 6 to 10 inch range for the central mountains and Flat Tops. The northern mountains will see around a foot of snow with higher amounts expected for the Park Range. Issued a Winter Storm Warning for the northern mountains and Advisories for the Flat Tops and central mountains starting tomorrow through noon Thursday. Interesting to note that latest guidance has started picking up on some banded precip occurring late Wednesday evening through Thursday morning and if these bands setup, some heavier snowfall rates may be realized. A few lingering showers will persist Thursday but the bulk of precip will be over. High temperatures, even with the clouds and precip, will remain above normal through the period.

LONG TERM /THURSDAY THROUGH TUESDAY/

Issued at 136 PM MST Tue Feb 10 2026

Low pressure passes through the region Friday through Friday night leading to another round of precipitation. There remains a lot of variance between model solutions at this time so the details will likely change between now and then, but this warm, moist, and progressive system looks to favor the southern mountains. Lower snow amounts are favored due to warm temperatures and the fast-moving nature of this storm, but mountain passes could become slippery, especially after the sunsets Friday evening.

High pressure returns for the weekend before another active weather week sets up with low pressure dropping in along the West Coast. Precipitation types and amounts will once again hinge on how much cool air is or isn't available. Early guidance is promising for temperatures that support snow in the mountains, but stay tuned as we dial in the details over the next several days.

AVIATION /00Z TAFS THROUGH 00Z THURSDAY/

Issued at 433 PM MST Tue Feb 10 2026

A low pressure system is approaching the region which has prompted denser cloud cover across the region alongside isolated areas of precipitation. All terminals are expected to experience VFR conditions through 12Z tomorrow morning, though there is a low probability for some reduced vis from snow showers at KHDN for the next couple hours. Tomorrow morning, rain and snow showers pick back up with the strongest showers occurring in the afternoon. Cigs may fall below ILS breakpoints where showers occur, and reduced vis could prompt MVFR to IFR conditions. Mountain obscuration will be of concern as well. Active weather is expected for most of the week.
