Salt Lake City, UT – The Wasatch Front wakes to calm skies and crisp air this morning as Utah edges into a quieter stretch of early December weather. After days of wind and haze, conditions are now mostly sunny — but don’t let the calm fool you. A colder push of air is set to slide in by the weekend, bringing frost risks and a hint of winter’s return.
According to the National Weather Service in Salt Lake City, temperatures will stay mild through Thursday, with highs near 58°F under steady sunshine. By Friday night, however, cooler air will spill south, dropping overnight lows into the mid-30s. That shift could introduce the first widespread frost across the valley since late November, with higher elevations possibly seeing a light dusting of snow.
Drivers should stay alert for slick spots early Saturday where moisture lingers on shaded roads or bridges. While no major storm systems are forecast this week, long-range models show an increasing chance for a wintry mix developing over northern Utah between December 14 and 17, especially near the Wasatch peaks and I-80 corridor.
By the weekend, expect partly cloudy skies, highs in the mid-50s, and crisp, dry air — ideal for outdoor holiday lights, early ski prep, or winter hikes. Still, pack layers and plan for chilly mornings as Utah slides into its next cold phase.
Five-Day Outlook (Salt Lake City, UT):
- Thursday: Sunny, high 58°F. Calm winds.
- Friday: Sunny, high 55°F. Evening lows near 35°F.
- Saturday: Partly cloudy, high 56°F. Frost early.
- Sunday: Mostly sunny, high 55°F. Light winds.
- Monday: Sunny start, high 55°F. Possible rain chance late.
