Mile High Tinderbox as Red Flag Winds Whip Denver

Denver is starting Wednesday, June 10, under clear skies and a crisp 57F at KBJC, but the cool, calm vibe will not last. The National Weather Service has issued a Red Flag Warning from noon to 8 p.m. MDT for the plains east of IAD25, where low humidity and gusty winds will turn any spark into a real problem. Temperatures will climb toward a high near 90F this afternoon as south-southwest winds ramp up through late morning and into the day. If you live or work east of IAD25, steer clear of open burning, heavy yard work, and any spark-producing activities while the Red Flag Warning is in effect.

Afternoon Winds Pick Up

The sun will dominate the sky, but the real story is at ground level, with south-southwest winds around 3016 mph and gusts up to about 28 mph possible this afternoon. Relative humidity on the plains will sink into the low teens, a combo that makes rapid fire spread much more likely. According to NWS Denver/Boulder, the warning zone covers portions of the eastern plains and has been expanded to include Lincoln County and eastern Elbert County.

Tonight's Cold Front Brings Brief Relief

Overnight, a strong cold front slides through, flipping winds around to the north and bringing gusts generally between 35045 mph behind the boundary, with even stronger gusts in exposed mountain corridors. That front will shave back Thursday's heat, with highs closer to 80F and lighter northeast winds expected. Even with cooler air moving in, the brief burst of postfrontal gustiness could still kick up fire behavior in a few spots.

Weekend Outlook And Thunderstorm Chances

Temperatures bounce back Friday and Saturday, returning to the upper 80s to low 90s ahead of a more noticeable cooldown late Saturday into Sunday. There is a small chance for showers and storms Saturday night, with Sunday shaping up as the better bet for more widespread showers and thunderstorms and highs down into the low 70s. If you are planning anything outdoors, keep an eye on the timing. Sunday afternoon in particular looks like the most unsettled stretch.
