Colorado — The morning starts cold across the Front Range, with breath visible and frost clinging to windshields. By afternoon, sunlight quickly softens the chill, hinting at a dramatic December shift already underway.
According to the National Weather Service in Denver-Boulder, temperatures begin near 30 degrees early today, then climb sharply. Highs reach around 63 degrees this afternoon under mostly sunny skies. Winds stay light, keeping travel smooth across I-25 and I-70 through the metro.
The mild trend strengthens Monday. Overnight lows dip into the mid-30s, followed by abundant sunshine and a high near 65 degrees. The warm air feels unusual for mid-December, especially as much of the Midwest remains locked in winter cold. Roads stay dry, and no Weather Alerts are posted for Denver.
Tuesday holds steady, with highs again near 63 degrees. Calm conditions dominate the day, making it a favorable window for errands, travel, and outdoor work. Snowmelt continues, though shaded areas may refreeze overnight, creating brief slick spots early each morning.
Changes arrive midweek. Wednesday turns breezy, with highs climbing into the upper 60s ahead of an approaching system. By Wednesday night, a slight chance of rain mixing with snow develops as temperatures fall back toward the mid-30s. Accumulation looks limited for now, but the timing could affect late-evening travel.
This pattern reflects a classic December temperature swing. Warm afternoons contrast with chilly nights, raising the risk of black ice where melting refreezes after sunset. Drivers should stay alert on bridges and side streets.
With Christmas travel approaching, this stretch offers mostly favorable conditions. Still, the late-week shift signals winter is not finished yet.
