Colorado – A low gray ceiling hangs over the Grand Valley before sunrise, casting a muted glow over the mesas while the air feels cool and slightly damp. Light east winds brush across the valley floor, and the stillness hints at a pattern about to shift as early Thanksgiving travel begins across western Colorado.
According to the National Weather Service, today starts quietly with partly sunny skies and highs near the upper 50s. Some light fog may cling to low spots early, but visibility should improve by midmorning. The calm won’t last long. Models signal a Winter Tease as a weak disturbance approaches from the west tonight, bringing a slight chance of showers after midnight.
The main system arrives Wednesday night. A 20 percent chance of showers develops after 11 p.m., followed by steadier moisture Thursday morning. Thursday carries a 30 percent chance of rain, mainly after 11 a.m., with highs near 53. Travel along I-70—especially east toward De Beque Canyon—could slow at times as pavement becomes slick and visibility fluctuates under low clouds.
Temperatures drop into the upper 30s Thursday night, and while snow stays confined to higher elevations, residents traveling toward Vail Pass or the Eisenhower Tunnel should monitor for fast changes. No accumulating snow is expected in Grand Junction, but colder air layers in behind the system, setting up a more classic November feel heading into the weekend.
Friday turns drier and partly cloudy with a high in the low 50s, giving travelers a cleaner window ahead of the heavier weekend movements. Saturday and Sunday stay sunny and cool—ideal for errands, packing, or early trips before another pattern shift next week.
