A line of strong storms are bringing some severe threat and a heavy drenching to the south suburbs and northwest Indiana overnight Friday into Saturday.



A Flood Advisory is in effect for all of the above counties until 2:30 a.m.

Damaging winds, large hail and brief tornadoes are all possible Friday evening, ABC7 Meteorologist Cheryl Scott said. Scattered thunderstorms are already developing south of the Kankakee River Valley, and could become strong to marginally severe. Lightning and soaking downpours are the main hazards of these storms, but gusty winds, small hail and even a brief tornado or two are possible.

But most likely threat is flooding as drenching rains fall overnight.
