Grand Junction, CO – A chill is creeping back into western Colorado as November ends, signaling a clear shift toward winter. By Sunday, crisp air and a mix of rain and wet snow could slow travel across the Grand Valley, marking the first real hint of December’s colder pattern.
According to the National Weather Service, a broad trough of cold air will settle over much of the U.S. early next week, driving temperatures well below seasonal norms. Grand Junction will see highs near the upper 40s Saturday before dropping into the low 20s by Sunday night, with a 30% chance of rain and snow showers. Roads could turn slick—especially for travelers heading east toward the higher elevations or returning from post-Thanksgiving trips.
Meteorologists expect this cold trend to deepen through early December, part of a larger national shift shown on NOAA outlook maps. Much of the central and eastern U.S. may see below-normal temperatures between December 2–6, with the potential for heavier snowfall across the Midwest and Great Lakes.
Locally, skies remain mostly sunny through Saturday, but clouds increase Sunday as moisture moves in. By Monday, drier air returns with highs only in the low 40s—cold enough for early morning frost and icy windshields.
