Grand Junction, CO – A brisk start across western Colorado and eastern Utah this Friday hints at a changing pattern. After a clear, calm day with highs near 65°F, colder air begins sliding in through the weekend, setting up the region’s first early-season taste of winter.
According to the National Weather Service in Grand Junction, rain and snow showers will persist over the San Juan Mountains through tonight, tapering before another system moves in late Sunday. Travelers heading toward higher passes should prepare for wet pavement and occasional slush above 9,000 feet. Thunderstorms remain possible in southern ranges, while valleys could see patchy fog by early Saturday.
Saturday stays mostly sunny and mild, reaching the upper 60s before clouds return Sunday afternoon. Forecasters expect measurable mountain snow Sunday night into Monday as a new disturbance crosses the Rockies. Monday’s highs will rebound near 60°F in the valleys, but morning frost is possible where skies clear early.
The overall setup points toward a steady cool-down next week, with Halloween week starting dry but chilly. Trick-or-treaters may need light jackets as evening temperatures drop into the 40s across much of western Colorado.
For now, the West’s higher peaks will carry the weekend’s most dramatic scenes—fresh snow dusting ridges while the valleys hold on to fall’s final warmth.
