Denver, Colorado — Mild and mostly dry weather will carry the Front Range through New Year’s Eve tonight and into New Year’s Day, while light to moderate snow returns to Colorado’s mountains, creating potential travel issues on high-elevation roads.

According to the National Weather Service in Denver/Boulder, plains locations including Denver, Boulder, Fort Collins, Greeley, and Castle Rock will remain dry and mild, with New Year’s Eve evening temperatures in the 40s and midnight readings in the upper 30s to low 40s. No precipitation or travel hazards are expected in metro areas tonight or early New Year’s Day.

Snow is expected to redevelop in the mountains on Thursday (New Year’s Day) and continue into Friday, with light accumulations in the Front Range mountains and Summit County, and several inches likely in the Park Range. While impacts are expected to be limited overall, mountain travelers should prepare for winter driving conditions.

Roadways most likely to be affected include I-70 through the Eisenhower–Johnson Tunnels, Vail Pass, Loveland Pass, Berthoud Pass (US-40), Rabbit Ears Pass (US-40), and US-285 over Kenosha Pass. Periods of snow-covered pavement and reduced visibility are possible during heavier snow showers.

Across the plains, including I-25, I-70 east of Denver, US-36, and E-470, roads are expected to remain dry and clear, supporting safe New Year’s Eve and New Year’s Day travel.

Looking ahead, Saturday and Sunday turn dry again statewide, with continued mild temperatures. Another chance for light mountain snow may return early next week.

The National Weather Service advises anyone heading into the mountains for New Year’s Day recreation or travel to check pass conditions, allow extra travel time, and carry winter supplies, while metro-area residents can expect a quiet and mild start to 2026.
