Grand Junction, CO – Western Colorado wakes to crisp, clear air this Thursday morning as early sunlight breaks over the Grand Mesa, signaling a calm but changing stretch of weather. After several chilly starts, the region heads toward an unusually mild December weekend — but residents shouldn’t pack away their coats just yet. A quick cold snap is expected to slide in by late Sunday, bringing frosty nights and slick morning commutes into next week.

According to the National Weather Service, Thursday and Friday will stay dry and bright, with highs reaching the mid-50s under mostly sunny skies. Winds remain light, and travel across the I-70 corridor should stay smooth through Saturday. However, temperatures will tumble again by Sunday night, dipping near 30°F — a sharp reminder that December frost is returning.

Forecasters say calm air will dominate through Saturday, but the clear skies mean surface heat escapes fast after sunset. That sets the stage for patchy frost and possible “flash freezing” on shaded roadways late Sunday into early Monday, especially where daytime melting occurs. Drivers should slow down and watch for slick patches early next week.

The good news? Sunshine continues into midweek, offering comfortable afternoons for errands or early holiday decorating. But the pattern shift signals the start of winter’s grip — with colder air deepening across the Rockies and a stronger storm track setting up to the north.
