Chicago Weather Forecast: Severe Storms Expected Wednesday Through Thursday
The National Weather Service (NWS) has issued a Severe Thunderstorm Watch for parts of northern Illinois, including Chicago, effective from 2 PM CDT Wednesday through 8 PM CDT Thursday, according to a statement released Tuesday. The alert highlights risks of hail, damaging winds, and isolated tornadoes, with the greatest threat expected during the afternoon and evening hours.
What Are the Specific Weather Threats?
Forecasters predict thunderstorms capable of producing hail up to 1 inch in diameter, winds exceeding 60 mph, and a low probability of tornadoes, the NWS reported. While tornadoes are less likely compared to other severe weather events, the agency emphasized that even a single tornado could cause localized damage. The storms are expected to move through the region in multiple bursts, with the first round arriving Wednesday afternoon and a second wave potentially developing Thursday.
How Are Local Authorities Responding?
Chicago’s Office of Emergency Management and Communications (OEMC) has advised residents to monitor weather updates and avoid unnecessary travel during peak storm periods. “Residents should secure outdoor items, stay indoors during lightning, and be prepared for possible power outages,” said a spokesperson for the OEMC. The city’s emergency management team is coordinating with the NWS to provide real-time updates through its official website and social media channels.
Why This Forecast Matters: Historical Context
Severe weather events in Chicago have previously caused significant disruptions, including the 2017 derecho that knocked out power for over 100,000 households. While the current forecast does not indicate a storm of that magnitude, the NWS notes that even localized severe weather can lead to hazardous conditions, particularly for those in high-risk areas such as Lake Michigan’s eastern shore.
What Should Residents Do to Prepare?
The NWS recommends creating an emergency kit with essentials like flashlights, batteries, and a first-aid kit. Residents should also download the NWS’s Weather Radio app for real-time alerts. For those in areas prone to flooding, the city’s Department of Water Management has issued a separate advisory, urging homeowners to check drainage systems and avoid driving through flooded streets.
What’s Next for the Forecast?
As of Tuesday evening, the NWS is tracking a potential low-pressure system that could intensify over the Great Lakes, increasing the likelihood of severe weather by Thursday afternoon. Updates will be provided through the NWS Chicago website and local news outlets. Residents are encouraged to follow official channels for the most accurate and timely information.
