Isolated instances of damaging straight-line winds and some hail are possible this afternoon across northern Illinois, northern Indiana and possibly portions of southern Lower Michigan, according to a “Mesoscale Discussion” that the National Weather Service Storm Prediction Center issued at 2:10 p.m. EDT.

Meteorologists at the time did not anticipate issuing a watch for the area, but they planned to monitor thunderstorm trends this afternoon to determine if a watch will become warranted.
