Salt Lake City, UT – Mountain communities across Utah could see accumulating snowfall beginning today and continuing through Thursday afternoon, with the heaviest precipitation expected early Wednesday as a moist southwest storm flow moves into the region.
According to the National Weather Service in Salt Lake City, warmer, moisture-rich air will arrive Tuesday, spreading periods of mountain snow and valley rain or snow as it interacts with a weakening atmospheric river. The most intense snowfall is expected to develop early Wednesday and persist in waves through 5 p.m. Thursday.
Forecasters stress that confidence in exact snowfall totals remains low, due to uncertainty in how long the moist flow lingers and how individual weather disturbances move through the state. As a result, snow amounts could vary significantly from one mountain range to another.
NWS guidance shows a wide range of possible outcomes, with lower-end projections representing a 90% chance of exceedance and higher-end amounts reflecting a 10% chance scenario. This means some locations may see only modest snowfall, while others—particularly in favored mountain zones—could receive substantially higher totals if storm timing aligns.
Mountain passes, including routes through the Wasatch Range, Bear River Range, and portions of central and southern Utah high terrain, could experience slick travel conditions, especially during heavier snowfall periods Wednesday into early Thursday. Drivers heading into higher elevations should be prepared for winter driving conditions and rapidly changing visibility.
Valley areas may see periods of rain mixed with snow, though significant accumulation is less likely outside higher elevations.
Residents are encouraged to monitor updated forecasts and advisories as the storm evolves, since timing and snow levels could shift with little notice.
