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.

A California farmworker died on Friday from injuries sustained a day earlier when U.S. immigration agents raided a cannabis operation and arrested hundreds of workers, according to a farmworker advocacy group.
