KEY MESSAGES

- Patchy fog will dissipate this morning across northern Utah valleys and near Evanston, WY.

- A cold, Pacific system will impact the region later Monday into Wednesday morning. Accumulating snow will impact most Utah mountain locations as well as the Wasatch Back. Expect the heaviest totals across the upper Cottonwoods and southern Mountains.

- Another colder Pacific system will impact the region Thursday into early Saturday. Snow levels will lower to near to below 5000 feet by Saturday morning.

DISCUSSION, Issued 1007 PM MST Sat Nov 14 2026

Clearing skies behind today's cold front will make for quite the crisp night across Utah and southwest Wyoming, with some of the coldest low temperatures of the season so far. Many lower elevation valleys will see temperatures dip into the low to mid 30s, except the low 40s across lower Washington County. Given recent rainfall and clearing skies tonight, there is a 20% chance for fog-prone areas across the Cache Valley and Wasatch Back to see freezing fog develop overnight. The limiting factor will be how quickly a deck of high clouds moves into the region, as these clouds could limit radiational cooling overnight.

High pressure builds in across the Intermountain West on Sunday into Monday, keeping conditions dry and mild through this period. This pattern will be brief, as another system is slated to impact the region on Tuesday. This next system looks quite similar that of today's: a fast-moving negatively tilted trough swinging through the Great Basin, bringing widespread rain and mountain snow ahead of a cold front. As such, likely looking at similar impacts with this upcoming storm. H7 temperatures around -4 to -5C indicate snow levels as low as 7000 feet, though best chances for accumulating snowfall will generally be above 8000-9000 feet. Current forecast calls for snowfall amounts between 3 to 8 inches for most mountains above 8000 feet, except locally up to 10 inches for the southern mountains.

Behind the cold front passage late Tuesday, precipitation gradually tapers off through early Wednesday, drying out briefly ahead of yet another storm expected to impact our area on Thursday into Friday. There is more considerable uncertainty regarding this late-week storm, as models struggle to converge on the track and magnitude of the associated closed low. While this system is likely to bring another round of widespread precipitation, the uncertainty lies in the precipitation accumulations and just how cold of an airmass this storm brings to the region. Current H7 temperature spread late Thursday is between -3 to -9C, with the latter supportive of snow down to valley levels. This scenario is still on the lower end, with around 20% of models resolving this colder airmass, but still something to keep an eye on as we get closer.

AVIATION
