Thunderstorm warning issued for parts of Chicago area amid heavy rain and high winds – NBC Chicago

A thunderstorm warning was issued for parts of the Chicago area Saturday morning, with several cities experiencing heavy rain, high winds and flooding.

The National Weather Service issued a severe thunderstorm warning for Kane, Kendall and DeKalb counties until 10 a.m.

On Saturday morning, parts of Cook and Will counties were experiencing flooded roads and overpasses after storms swept through the area, bringing heavy rain and damaging wind gusts of up to 60 mph, triggering tornado warnings for both counties.

Just after 6 a.m. Saturday, a severe thunderstorm warning remained in effect for Cook, Will, and southern parts of DuPage counties after tornado warnings expired. By 7 a.m., the storm moved into northwest Indiana, and many counties in the Chicago area were under flood watch.

A tornado also likely touched down south of Naperville early Saturday morning, according to National Weather Service data.

An initial storm survey showed a tornado in the western suburbs based on observed damage and a downwind tornadic debris signature on radar, meteorologists said.

The approximate starting point was a strip mall at the northeast corner of Route 59 and 95th Street, although an assessment is still underway.

High winds and heavy rain were the main threats from the initial storm, and nearly 150 homes were without power Saturday morning.

“The tornado threat has subsided, although still high winds (over 60 mph) are moving through parts of Illinois along/east of I-57 and into northwest Indiana,” the National Weather Service tweeted. “The message before these storms remains largely similar – get inside, away from windows.”

Flooding was reported throughout the area, from the Oak Park underpasses to the roads of Hoffman Estates. Flooding was also reported on the Eisenhower Freeway, slowing traffic as cars drove through the water.

The threat of storms is expected to lessen in the region later Saturday morning and into the afternoon, but a chance of severe weather is again possible Saturday evening through Sunday. High winds and heavy rain are again considered the main threats, with the possibility of a tornado.

Conditions could be hot on Saturday as temperatures of 91 degrees are possible.
