The storms triggered tornado sirens and downed trees and power lines in the suburbs Monday night.
The National Weather Service first issued a tornado warning around 6 p.m. for northeast Kane County and northwest Cook County, then later around 7 p.m. for DuPage County, after it was said that a severe thunderstorm over West Dundee or Carpentersville was capable of produce a tornado due to the rotation of the clouds. But no tornado touchdowns were reported.
The storm was near the Barrington and East Dundee area, as well as Streamwood, Hoffman Estates, Inverness, Hanover Park, Roselle, Schaumburg and Palatine. It spread to some towns in DuPage County, with rotating clouds over Itasca and Medina, ABC 7 reported.
Residents reported fallen trees and other damage in Schaumburg, Mount Prospect, Arlington Heights and Roselle.
In Algonquin, a lightning strike started a house fire.
Firefighters responded just before 6 p.m. at the 600 block of Chelsea Drive, according to the Algonquin Fire Department. Authorities said the department received 911 calls from occupants of the building, who had fled to a nearby residence. No one was hurt.
Lightning tore a hole in the siding of the house and caused a fire in the attic. Lightning also damaged a nearby tree. Authorities estimated the damage at $100,000 and said the house was uninhabitable.
One of Roselle’s oldest trees gave way to sudden high winds, ABC 7 Chicago reported. But the direction of the tree’s fall spared the mayor’s house.
“I was at town hall, I got a lot of calls from my wife,” Mayor David Pileski said. “She was in our basement with our one-year-old. We’re just grateful he fell away from home.”
A spontaneous cleanup crew emerged to help as soon as it was safe to get out.
“I live two houses away, that’s what the neighbors do,” Joe Kightlinger said. “Roselle, they take care of each other.”
The Metra UP-Northwest line was suspended as the storm passed, according to tweets from Metra. The weather service reported gusts of up to 84 mph at O’Hare International Airport and 69 mph at Midway International Airport.
All arriving and departing flights stopped at O’Hare, ABC 7 reported, and crowds of people seeking shelter rushed to the lowest level of the airport.
Strong winds overturned several planes at Schaumburg regional airport. And a single lightning strike started a fire in a Northbrook home.
The City of Elgin tweeted that the storm remained “mostly north of Elgin” and that the city was responding to calls for downed wires and assessing any further damage.
As of 10 p.m., ComEd reported that more than 33,000 people were without power due to the storms, down from a high of 88,000.
Parts of the Chicago area could see temperatures above 100 degrees Tuesday and Wednesday, combining with high humidity levels to create dangerous heat indices. A heat advisory is in effect for the area until 8 p.m. Wednesday.
On Tuesday, the forecast called for temperatures in the upper 90s with heat indices reaching 105 degrees.
High temperatures persist through Wednesday with an evening storm expected to bring cooler air to the region for the rest of the week and into the weekend.
The hottest Recorded June 15 happened in 1994 when temperatures soared to 95 degrees at O’Hare International Airport. Forecasts suggest Wednesday’s high could break that record.
With temperatures expected to hit the mid-90s on Thursday, meteorologists say the region will benefit from a break from the “oppressive humidity” of previous days.
