DENVER, Colo. – A sharp, cool dawn spread across the Front Range early Saturday, the air still and faintly metallic, signaling Colorado’s next seasonal turn. After a crisp start, sunshine dominates through Sunday before colder air sweeps in from the northwest by Monday, setting the tone for a frosty, late-October stretch.
According to the National Weather Service in Boulder, high pressure over the Rockies will weaken as a trough slides in from the northern Plains. Gusty northwest winds could reach 25 to 30 mph Monday afternoon, knocking down highs into the low 60s. The bigger story arrives late Monday into Tuesday, when clear skies and calm air will let temperatures plummet into the lower 30s—cold enough for patchy frost across eastern suburbs, especially along I-70 toward Aurora and Bennett.
Drivers should anticipate lighter traffic disruptions but brisk morning commutes, with frost potentially coating windshields early Tuesday. Gardeners and homeowners are urged to cover sensitive plants, protect outdoor faucets, and bring pets inside during the early-morning chill.
Sunday remains mild, with highs in the lower 70s and partly sunny skies, perfect for pre-Halloween yard cleanup or last-minute outdoor projects. By Halloween on Friday, expect clear skies, light winds, and cool 50s through evening—ideal for trick-or-treating but crisp enough for jackets over costumes.
After a warm and dry October, the Front Range finally hints at its colder rhythm. A chilly November lies just ahead.
