DENVER, CO – Colorado’s crisp fall weekend turns frosty as a Frost Advisory takes effect across the Denver-Boulder metro area, with temperatures expected to dip near 32°F by early Sunday. The National Weather Service in Boulder warns that residents should prepare now for cold-sensitive plant damage and gusty winds sweeping through the Front Range.
The advisory is in effect from 10 p.m. Saturday to 8 a.m. Sunday, covering Jefferson, Arapahoe, Adams, and Douglas counties, including Denver International Airport and areas along I-70 and C-470. Gardeners should cover tender plants or move them indoors before dusk to avoid frost burn.
Saturday brings a mix of sunshine and wind, with gusts topping 35 mph as a strong cold front pushes through. Temperatures fall quickly after sunset, setting up ideal conditions for frost formation, especially in low-lying neighborhoods like Parker, Aurora, and Littleton. Sunday morning starts cold but clears fast—expect highs near 77°F under mostly sunny skies.
Early next week, sunshine dominates again with breezy Monday conditions and highs near the upper 60s. Winds may gust up to 40 mph in foothill zones, prompting near-critical fire weather conditions by Tuesday.
Colorado’s weekend weather serves up the state’s classic October contrast: frosty dawns, golden afternoons, and gusty winds sweeping across the plains. Residents should brace for one of fall’s final cold snaps before mild, dry conditions return midweek.
