Chicago weather: Severe storms pass through Chicagoland, more threats possible Thursday

TL;DR

A series of severe storms moved through Chicagoland Wednesday evening, causing damage and power outages. Additional storms are expected Thursday, with potential for tornadoes and damaging winds.

Severe storms swept through the Chicagoland area Wednesday evening, bringing damaging winds, heavy rainfall, and widespread power outages. The National Weather Service issued multiple warnings, and officials warn that additional severe weather threats remain through Thursday night.

On Wednesday, strong thunderstorms produced wind gusts exceeding 75 mph, downing trees and causing power outages for over 270,000 residents, according to ComEd. The storms prompted severe thunderstorm warnings and a tornado watch for parts of Illinois, with the threat of brief tornadoes and damaging winds continuing into the night.

The National Weather Service indicated that a second round of storms is moving eastward across northern Illinois, with the potential for more wind damage, hail, and torrential rain. Airports at Midway and O’Hare temporarily halted ground operations due to the storms, and transportation disruptions persisted into the evening.

Officials forecast that the storms should exit the region by around 1 a.m. Thursday, but the threat of severe weather remains high throughout Thursday, with the possibility of tornadoes, damaging winds, and heavy rainfall between 4 p.m. and 10 p.m. Thursday’s weather conditions are expected to ease Friday, with cooler, less humid air moving into the area.
