GRAND JUNCTION, Colo. – Under a star-swept Halloween sky, the Grand Valley sits cool and calm this morning — clear air, quiet streets, and a faint bite of fall drifting from the Book Cliffs. The early chill will quickly fade as warm sunshine dominates through the weekend, making this one of the most comfortable stretches of late fall weather across western Colorado.
According to the National Weather Service in Grand Junction, skies remain clear Friday through Sunday, with highs climbing into the low to mid-60s and overnight lows settling in the upper 30s to low 40s. Light winds from the east and southeast will keep the air dry, ideal for outdoor cleanup or trick-or-treat events across Mesa and Delta counties.
Saturday and Sunday continue mostly sunny, with afternoon warmth returning near 68°F. The region’s mountain zones — including the Grand Mesa and Elk Range — will stay dry but start to trend cooler by late Sunday as higher elevation moisture builds north of I-70. That early pattern could mark the first sign of November snow for northern Colorado peaks next week.
For now, Grand Junction remains in a stretch of crisp mornings and mild afternoons. Clear skies and calm winds make for perfect conditions to wrap up outdoor chores, prep gardens, or install early holiday lighting before the weather begins its inevitable shift toward winter.
Residents should note Daylight Saving Time ends at 2 a.m. Sunday, bringing earlier sunsets and longer evening chill as the first week of November begins.
