Salt Lake City, UT – Frost glistens on rooftops this morning across the Wasatch Front as Utah braces for a quick return to winter. The calm, 34°F start belies what’s ahead — a new cold front arriving Sunday that could bring snow to the valleys and icy travel through early next week.

According to the National Weather Service, skies stay partly sunny Friday and Saturday with highs in the mid-40s. By Saturday night, clouds will thicken ahead of a colder air mass sliding in from the northwest. The first flakes could appear by Sunday morning, with a 60% chance of snow across Salt Lake City and neighboring valleys.

Accumulations should remain light — likely under half an inch — but the changeover from rain to snow may make roads slick for post-Thanksgiving travelers heading east on I-80 or south on I-15. Mountain areas could see steadier bursts, reducing visibility during midday travel. Calm winds will shift northwest as temperatures fall into the mid-20s Sunday night.

Monday looks brighter but brisk, with highs near 40°F and a crisp, dry chill in the air. The pattern remains unsettled into Tuesday and Wednesday, when another round of rain and snow could mark the start of an early-December cold stretch. Meteorologists call it a “winter tease,” hinting that heavier snow may develop across the Intermountain West next week.

Bundle up, Salt Lake — winter’s early edge is here.
