Illinois approaching record number of tornadoes this year

According to the National Weather Service, last week’s severe weather in northern Illinois produced 17 tornadoes. That brings the total number of tornados in the state this year to 138, just four shy of the record and we’re only midway through June.

A tornado Streator was one of the most severe so far this year. NWS says it was an EF-3, and it caused widespread damage to homes and businesses in town. But it was just one of more than a dozen tornados last week. A EF-1 touched down in Bartlett and Naperville causing some property damage as well though not as severe.

“Just remarkable unprecedented stretch of frequency of severe weather and tornadoes across the state,” Illinois climatologist Trent Ford said.

Ford says Illinois is on the verge of breaking the number of tornadoes in the state for the third time in the last four years. The current record of 142 was set in 2024. Ford says historically, the state has seen an unprecedented amount of tornado activity in the last several years. For more than 70 years from 1950 until 2022, Illinois had more than 100 tornadoes in a year four times. The last four years however have each seen more than 100 tornadoes, and he expects we will break the record soon for the third time this decade.

“Part of what we’ve seen over the last four years is the right conditions of whether at the right time in a contributions of a long-term trend,” Ford said.

Meteorologists consider tornado season to generally run from April through June. But Tornadoes can develop at any time of the year. Earlier this year in March, another EF-3 tornado ripped through Kankakee and Aroma Park, one of 12 in Illinois and northwest Indiana.

The state climatologist says this has been an unprecedented time for tornadoes and climate change is likely a factor, but he says it’s a complicated equation.

“Part of it is we’ve been in these patterns of variability of our weather that make for the right conditions at the right time,” Ford said. ‘So people can think of it as luck probably bad luck.”

Ford says looking at climate models suggests this trend will continue. The environments could lead to continued years of higher tornado activity.

Storms come as tornado cleanup continues

Many areas are still reeling from recent tornadoes as the next round of storms comes in.

The threat of more bad weather couldn’t come at a worse time. Many people are still cleaning up and recovering. And with heavy rains promised, some are wondering what’s next.

Al Mills was bracing for more storms Wednesday.

“It happened so fast; it was about five seconds,” Mill said.

He’s cleaning up from last week’s tornado damage that left his home, garage and car in shambles.

“I haven’t recovered from anything,” Mill said. “I mean, we have no power; there’s water coming in the basement from the rain. There’s been no recovery.”

It was expected to be another challenging day Wednesday for people in Merrillville, Indiana, especially with the promise of more severe weather.

It’s been nearly a week since an EF-2 tornado with winds up to 135 mph hit the northwest Indiana town, causing extensive damage to hundreds of homes and businesses. Fortunately, there were no serious injuries reported.

NIPSCO is still working to restore service to those who lost power because of the storms.

Wednesday morning, crews worked to secure the roof of a Catholic high school, while Thomas and Debra Avery tried to pump out the foot of rainwater already in their basement. Everything down there is a total loss.

“I just hope that I can keep the sump pump running where it’s not gonna flood again.,” Thomas Avery said. “I just got done getting all the water out; so I gotta keep this thing running.

And despite the challenge, the Averys, like a lot of people, are relying on their faith to keep them going.

“Just hope that everything’s OK,” Debra Avery said. “I’ve just been praying that the Lord will keep us all safe over here in our neighborhoods cause we got some awesome neighbors.”

Local officials said they are on alert too, ready to respond to any emergencies. They are encouraging residents to use their tornado recovery website to find helpful resources.

Meanwhile, the living hope church plans on offering food assistance Wednesday afternoon to those who need it.

There’s a tornado recovery website at merrillville.in.gov/tornado. It’s available for people in Merrillville with helpful resources, especially as this next round of storms blows through.
