Colorado – Flags snap hard, dry grass rattles, and loose debris skitters across pavement as dangerous fire weather takes hold along the Front Range. The air feels unusually dry for winter, and strong winds increase fast through the afternoon. Conditions remain volatile through Friday, with little room for mistakes.
According to the National Weather Service in Denver, a Red Flag Warning remains in effect through early evening, then returns Friday morning through Friday evening. Northwest winds reach 25 to 35 mph, with gusts pushing 45 to 55 mph at times. Relative humidity drops as low as 10 to 20 percent, creating prime conditions for rapid fire spread.
The highest risk targets the Denver metro area, including Adams, Arapahoe, Boulder, Broomfield, and Douglas counties. Any spark can grow quickly, especially in open spaces, grasslands, and foothill-adjacent neighborhoods. Outdoor burning, welding, or activities that throw sparks should be avoided entirely.
Travel impacts remain secondary but noticeable. High-profile vehicles may struggle along I-25, I-70, and east-west routes during peak gusts. Blowing dust and sudden crosswinds can reduce visibility, especially near open fields and construction zones.
Winds ease Friday night, allowing calmer conditions into the weekend. Sunshine returns Saturday and Sunday, with highs in the low to mid-40s Saturday and near 58 by Sunday. Nights stay cold, though, with lows dipping into the 20s. Any melted moisture may refreeze after sunset, creating isolated slick spots.
Fire weather threats diminish after Friday, but dry winter patterns linger across Colorado. Stay alert, secure loose items, and report smoke immediately. Conditions can change quickly under this setup.
