A tornado watch remains in effect for most of the Chciago area and parts of northwest Indiana, even after numerous touchdowns were reported during an outbreak of severe weather Monday.
The watch includes McHenry, Lake, DeKalb, Kane, DuPage, Cook, LaSalle, Kendall, Grundy, Will and Kankakee counties in Illinois, along with Lake, Porter, LaPorte, Newton and Jasper counties in northwest Indiana.
The watch will last until 10 p.m., according to the National Weather Service.
A series of tornado warnings were issued in DeKalb, Kane and DuPage counties, with multiple touchdowns reported in numerous communities across the area.
Some storm damage was reported in Burlington, among other communities, but the full scope of the damage is unknown at this time.
Even after severe weather moves out of the area, the Chicago area will see a new threat on Tuesday: oppressive heat indices that could easily exceed 100 degrees and could approach 110 in some locations.
Areas to the south and west of the Chicago metropolitan area will likely see the highest heat indices, prompting a heat advisory from the National Weather Service for all of northern Illinois and northwest Indiana.
