Utah drivers wake to damp pavement and low clouds as precipitation spreads across the Wasatch Front. Rain taps rooftops early, but colder air is already pressing in, setting up a messy transition before many holiday trips begin.

According to the National Weather Service in Salt Lake City, rain is expected to mix with snow this morning, then change to mostly snow by afternoon. Temperatures hover in the upper 30s, which could allow slushy accumulation on untreated roads. Even a light coating can create slick conditions during busy travel hours.

Snow chances remain high into tonight, with minor accumulations possible across the valley floor. Areas near benches and higher elevations may see more noticeable impacts. Drivers along I-15, I-80, and surface streets should expect reduced traction at times, especially after sunset as temperatures drop into the low 20s.

Conditions improve quickly on Sunday. Skies clear, sunshine returns, and highs reach the mid-30s. While roads dry out, cold overnight lows near the teens raise concern for refreezing where snowmelt lingers. Black ice may develop in shaded areas early Monday.

The quieter pattern holds into early next week. Monday and Tuesday stay sunny with highs climbing into the upper 30s and low 40s. Travel conditions look favorable across northern Utah as many head home or prepare for New Year’s Eve plans.

Looking ahead to New Year’s Day 2026, clouds increase with a slight chance of rain or snow returning. Impacts appear limited for now, but changing temperatures could once again affect road conditions.

Plan slower travel today, especially during snowfall periods. Allow extra stopping distance and keep winter gear handy. Are you heading out during the storm window, or waiting until roads improve?
