Denver, Colo. – Drivers and residents across northeast Colorado should brace for gusty winds and scattered thunderstorms returning Tuesday, September 9. Afternoon storms could bring brief downpours, creating slick roads on major highways including I-25 and I-70 during the evening commute.
According to the National Weather Service in Boulder, outflow winds could reach 40 mph Tuesday afternoon. Heavy rain is possible in short bursts, raising the risk of minor flooding in low-lying areas and creating sudden visibility issues for drivers. While storms are not expected to be widespread, a few cells across eastern Colorado could become severe.
Travelers in Denver, Aurora, and Boulder should plan for changing conditions late Tuesday, especially between 3 p.m. and 9 p.m. Motorists are urged to slow down, avoid flooded intersections, and allow extra time for rush-hour travel. Residents in foothill communities should monitor conditions closely as storms develop over higher terrain before drifting east.
The rest of the week looks quieter but not completely dry. Wednesday will be mostly sunny with highs near 89 degrees, though isolated showers could return overnight. Thursday and Friday bring another chance for afternoon storms, with slightly cooler air filtering in by the weekend.
Warm, mostly dry weather should settle in by Sunday, offering a more stable stretch. Still, forecasters note that late-summer instability could continue to trigger isolated activity in the mountains and plains through mid-September.
Warnings will be updated if severe storms develop Tuesday afternoon. Residents should keep phones charged, monitor local alerts, and stay prepared for sudden changes.
