Colorado – Wet pavement glints under early sun across the Front Range, a quiet warning after light snow fades. Denver wakes near 18 degrees, and refreeze lingers on neighborhood roads, ramps, and shaded sidewalks this Monday morning.

According to the National Weather Service in Denver/Boulder, snow is ending early, but temperatures stay below freezing through much of the morning. Slick spots remain likely as meltwater hardens again, especially along I-25, I-70 viaducts, and west-facing side streets. Drivers should slow down and expect isolated icy patches through mid-morning.

Sunshine takes over by late morning, and conditions improve steadily. Highs reach the mid-40s today with light winds, helping dry roads by afternoon. Still, as the sun drops this evening, refreezing returns quickly. Plan errands early and use caution after sunset.

A notable shift follows. Tuesday turns brighter and warmer, climbing to the mid-50s. Wednesday pushes even higher, near 62 degrees, a sharp turnaround that feels almost springlike for late December. To be fair, that warmth comes with a catch. Snowmelt during the day can refreeze overnight, renewing slick conditions in parking lots and along curbs.

Attention then turns to New Year’s Eve and New Year’s Day 2026. Clouds increase Wednesday night, but dry weather holds. Thursday stays mostly cloudy with highs near 60 degrees, favorable for travel and outdoor plans across Denver, Boulder, and surrounding suburbs.

No major storms are expected this week, though mountain snow chances return late in the period. For now, the biggest risk remains timing—cold mornings, warmer afternoons, and icy refreezes at night.

Plan extra time early today, watch shaded roads, and enjoy the warm-up ahead. Did you notice slick spots on your commute this morning?
