Severe thunderstorms are anticipated across a large part of the Chicago area on Wednesday, with risks of hail, tornadoes, and flooding, as per the National Weather Service (NWS).
The region experienced showers early in the day, with a higher probability of storms expected by the afternoon. The NWS has warned of an elevated chance of flooding, gusty winds reaching up to 70 miles per hour, quarter-sized hail, and possible tornado activity, primarily southeast of Interstate 55 in eastern Illinois and northwest Indiana.
Gino Izzi, a meteorologist with NWS, indicated that while the likelihood is higher south of the city, there remains a chance for severe weather in Chicago itself. He emphasized that regardless of severe storms, residents should prepare for substantial rain and thunderstorms, which are forecasted for the day.
The storms are predicted to move east and northeast at approximately 30 miles per hour. Moreover, storms in southeast Wisconsin could potentially affect the northeast portion of Illinois on Thursday and Friday, although any severe conditions are expected to be short-lived.
Looking ahead, the remainder of the week is expected to bring milder weather with less precipitation. However, temperatures are forecasted to rise, leading to hot and humid conditions over the weekend, with heat index values possibly reaching 100 degrees or more. Izzi noted that this marks the first significant heat wave of the year, describing it as typical for a Chicago summer.
This rise in temperature may prompt residents to take necessary precautions, especially those with health concerns regarding extreme heat. It’s also a reminder of the changing seasons and the potential for varied weather patterns as summer approaches.
