Get ready for a round of late-night gusty t-storms. The storms will develop over northwest Indiana after Midnight and quickly move southeast. The storms will produce frequent cloud to ground lightning and thunder will accompany the storms. A few severe t-storm warnings are possible as the storms pound the area.
The storms are now forming across northern Illinois.
Heavy rain, small hail and gusty winds will move through the nine county metro area between 4am and 7am.
Up to an inch of rain is likely through lunchtime Friday.
