DENVER, Colo. — The Front Range woke to a frosty silence this Tuesday morning, every rooftop glittering under a pale moon and the sharp sting of 20-degree air. The season’s coldest stretch so far grips much of northeast Colorado, prompting the National Weather Service to keep a Freeze Warning in effect through Wednesday morning.
For early commuters, the bite is immediate. Windshields are iced solid, and patches of frost cover lawns from Boulder to Castle Rock. Across the metro corridor, low-lying areas could dip to 24°F before sunrise. Homeowners should disconnect hoses, cover outdoor spigots, and protect tender plants. Unheated irrigation systems and gardens are especially vulnerable to damage tonight.
The cold front responsible for this drop is already easing south, leaving behind calm, dry air. Sunshine returns quickly Tuesday afternoon, but temperatures will struggle to reach 49°F. By Wednesday, light southeast winds bring a modest rebound with highs climbing near 58°F.
Thursday and Friday will mark a welcome shift — highs in the low to mid-50s Thursday, warming to near 54°F by Friday. Trick-or-treaters can expect crisp but pleasant Halloween conditions: clear skies, calm winds, and evening readings in the upper 40s.
The weekend holds a brighter note. Highs rebound into the 60s by Saturday and near 65°F Sunday, a mild setup before models hint at another November chill next week.
