Colorado — Sunshine and mild air are giving Denver a calm start, but a sharp shift is already lining up to disrupt travel early next week as a storm builds over the Rockies.
According to the National Weather Service, dry and quiet conditions hold through today and the weekend across Denver, Boulder, Fort Collins, Aurora, and Greeley, with highs climbing into the upper 60s and low 70s by Sunday afternoon.
This is part of a broader system moving in from the west that will tap colder air and mountain moisture, setting up accumulating snow and travel hazards beginning Monday.
The first impacts develop between 3 p.m. and 10 p.m. Monday, when rain spreads into the Denver metro and quickly transitions to snow in higher elevations west along I-70. Slick roads and reduced visibility are likely through the Eisenhower Tunnel corridor and into Summit County, where snow could accumulate within hours on colder surfaces.
By late Monday night into Tuesday morning, colder air deepens, increasing the risk of slushy accumulation even on untreated roads in foothill communities like Golden and Evergreen. Rapid temperature drops may create patchy icy spots on bridges and elevated roadways.
Drivers should plan for slower travel along I-70 and U.S. 285, especially in higher terrain. Secure travel plans early and monitor changing road conditions as visibility may drop quickly in bursts of heavier precipitation.
The weekend remains warm and quiet, but conditions will deteriorate quickly Monday evening as the storm intensifies across the mountains.
