Colorado heat surge and thunderstorms raise flash‑flood risk in Colorado and Wyoming

The National Oceanic and Atmospheric Administration’s Climate Prediction Center projects above‑normal temperatures across Colorado from July 23‑27, accompanied by increased monsoonal moisture that will fuel daily afternoon and evening thunderstorms. Storms are expected to produce heavy rainfall, frequent lightning, wind gusts exceeding 40 mph and localized flash‑flooding, especially near recent wildfire‑burn scars, on the Front Range and in mountainous terrain. Travel on Interstate 25 and U.S. Highway 24 may be affected, and residents are advised to schedule outdoor activities early and stay alert for rapid flooding.

In Cheyenne, Wyoming, the National Weather Service warns of highly variable high‑plains weather, with rapid temperature swings, strong westerly winds and occasional chinook‑induced temperature spikes. Localized storm cells can develop quickly, bringing brief thunderstorms, high‑wind warnings and gusts that may impact travel and outdoor safety. Authorities recommend maintaining an emergency kit in vehicles and monitoring official forecasts for updates.
