Chicago weather remains unsettled heading into the weekend, with a severe storm threat Friday evening that brings the possibility of tornadoes and flooding.

A tornado watch was still in effect until 11 p.m. Friday for Cook County and northern Illinois, but the severe weather mainly stayed northwest of the Chicago area thanks to a line of cool, dense air that broke the storms up.

Potentially dangerous storms accompanied by damaging winds and hail were possible in the Chicago area on Friday night.
