DENVER, Colo. — A crisp, metallic dawn greeted the Front Range early Saturday, a clear signal that Colorado is easing into its next season. After that cool start, sunshine holds strong through Sunday. By Monday, a push of colder air from the northwest arrives, setting up a frosty pattern for the final days of October.

Forecasters at the National Weather Service in Boulder say a high-pressure ridge will give way as a trough drops out of the northern Plains. Expect a breezy northwest wind Monday afternoon, with gusts around 25 to 30 mph, keeping daytime highs in the low 60s. The main change comes late Monday into early Tuesday, when clear skies and light winds will allow temperatures to tumble into the lower 30s. Patchy frost is likely across the eastern suburbs, especially along the I-70 corridor toward Aurora and Bennett.

Motorists should plan for a brisk, possibly frosty start Tuesday, with the chance of ice on windshields. Homeowners and gardeners are encouraged to cover tender plants, insulate outdoor faucets, and bring pets indoors for the early-morning chill.

Sunday stays comfortable, reaching the lower 70s under partly sunny skies—great for pre-Halloween yardwork or wrapping up outdoor tasks. By Halloween on Friday, look for clear skies, a gentle breeze, and evening temperatures in the 50s—pleasant for trick-or-treating, but cool enough to warrant a jacket over costumes.

After a warm, dry October, the Front Range is finally leaning colder. A brisk November appears to be on deck.

Five-day outlook for Denver, CO:
– Sat: 72/44 – Sunny overall; light morning winds with some clouds increasing late.
– Sun: 71/42 – Partly sunny, mild; a light easterly breeze.
– Mon: 63/34 – Cooler with gusty northwest winds; a brisk feel.
– Tue: 54/31 – Cold start with patchy frost; mostly clear through the day.
– Wed: 62/35 – Sunny and calmer, with a gradual warmup.
