Denver, Colorado – Thunderstorms are expected to hit the Denver metro area again Thursday afternoon, with possible flash flooding along the I-25 and I-70 corridors as summer-like heat builds across the Front Range.
According to the National Weather Service in Boulder, Thursday will bring scattered afternoon and evening thunderstorms, especially over the foothills and adjacent plains. While the storms are not expected to reach severe levels, brief heavy rain, lightning, and gusty winds up to 17 mph could disrupt commutes and elevate flash flooding risks in low-lying areas.
Thursday’s high will reach 69°F, with most storms clearing by midnight. North winds will shift southeast in the evening. Spotter activation is not expected but could change if convection intensifies.
Local Impacts:
- Denver, Aurora, and Lakewood may see street flooding during peak evening travel.
- Hikers near Boulder and Golden should prepare for fast-moving storms in the foothills after 2 p.m.
- Residents along I-76 and US-36 should monitor alerts for sudden downpours.
Looking Ahead:
Friday and Saturday will remain unsettled, with afternoon thunderstorm chances at 30% and 20%, respectively. Highs will steadily climb to 80°F Friday and 88°F Sunday, marking the region’s warmest stretch since early spring.
Monday and Tuesday will feature continued daily storm chances and slightly cooler highs in the low 80s, extending this week’s wet and warm summer pattern.
Warnings remain possible each afternoon—check local alerts before travel or outdoor activities.
