Severe storms are forecast to sweep across the central and eastern United States, posing a significant threat of damaging winds and flash flooding throughout the week. These storms are fueled by lingering heat and high humidity, creating unstable atmospheric conditions ripe for severe thunderstorm development.

Starting in the Plains and Midwest, the storm systems are expected to intensify, potentially forming a derecho—a widespread, long-lived windstorm associated with fast-moving thunderstorms. Areas from Montana and the Dakotas to western Iowa and Missouri face the highest risk of destructive wind gusts, possibly reaching up to 90 mph, with localized peaks of 115 mph. Such winds could cause widespread damage to crops, structures, and trees. Additionally, the storms may bring flash flooding, hail, and isolated tornadoes.

The severe weather threat extends into major metropolitan areas such as Chicago, Milwaukee, and Indianapolis, potentially disrupting commutes and daily activities. As the cold front progresses, it will continue to trigger thunderstorms, with the risk of damaging winds and heavy rainfall persisting into Tuesday morning.

By Wednesday, the severe weather pattern will shift eastward, affecting areas from Montana and Missouri to the Ohio Valley and parts of New England. The primary hazards will remain damaging winds and flash flooding, with large hail also possible in some areas. Residents are urged to stay informed about weather updates and heed local warnings.

Looking ahead to Thursday, the risk of severe weather may spread further into the mid-Atlantic and the Carolinas. While heavy downpours capable of causing flash floods will be the main concern, any thunderstorm in the region could bring localized wind damage. Residents are advised to take necessary precautions, including securing outdoor items and having a plan in place for potential power outages or evacuations.
