DIXON – The National Weather Service is expecting stormy weather in northern Illinois through Tuesday night.

The NWS has issued a severe weather warning for parts of north-central Illinois, northeastern Illinois and northwestern Indiana.

Meteorologists are predicting a limited risk of flooding and thunderstorms throughout Tuesday, with a slight risk of damaging winds. The squall line is expected to arrive after sunset and move eastward across northern Illinois.
