A funnel cloud spotted near south suburban Calumet City prompted a tornado warning for Cook County and northwest Indiana on Wednesday evening.
The cloud did not touch the ground.
It was reported at 6:29 p.m. by local law enforcement. The National Weather Service said it was moving east at about 20 MPH.
Calumet City police said there were sightings of funnel clouds, but there were no reports of a tornado touching the ground.
The sighting prompted the weather service to issue a tornado warning for southeastern Cook County and northwestern Porter County (Ind.). By 7:15 p.m., the tornado warning moved west to southern Lake, northwestern Jasper, northeastern Newton and southwestern Porter counties in Indiana, the weather service said.
Wednesday's storms aren't expected to bring the heavy flooding that unloaded on Oak Lawn last week, prompting Mayor Dave Heilmann to call the deluge "the worst in years, maybe decades."
Rain could stick around through the weekend, so keep an umbrella close by.
