GRAND JUNCTION, Colo. – The Grand Valley woke under clear, cool skies early Saturday, the kind that seem deceptively calm before a pattern shift. Clouds will gather by late Sunday as a Pacific system slides through western Colorado, bringing rain to valleys and measurable snow to the high country by early Monday.
According to the National Weather Service in Grand Junction, high pressure will hold firm today, keeping temperatures 5 degrees above normal with afternoon highs near 68°F. By Sunday afternoon, that calm breaks down as the next wave approaches from the west. Showers are expected to develop over the Central Colorado River Basin and along I-70 east toward Glenwood Springs, while snow accumulations could begin over the Elk and Gore Mountains, the Grand Mesa, and the San Juans.
Travelers heading east Sunday night into Monday morning should prepare for slick mountain passes and reduced visibility above 9,000 feet. The National Weather Service notes that measurable snowfall is likely for northern and central ranges, tapering by late Monday as drier, colder air filters in.
Across the lower valleys, temperatures will dip from the upper 60s Sunday to low 60s Monday, with frost possible in sheltered areas by Tuesday morning. By midweek, the pattern turns tranquil again—sunny skies, chilly mornings, and highs in the lower 60s, perfect for final yard work or Halloween decorating.
After all, a chilly November isn’t far behind.
