An apocalyptic 'wall of dust' is set to blanket Chicago after severe storms ripped through the Midwest leaving at least 23 people dead and millions without power. A terrifying dust cloud descended onto the Chicago area as residents were choked and blinded by the 100-mile line of dust from southwest Chicago to northern Indiana.

An apocalyptical ‘wall of dust’ is barreling across Chicago – so vast that it is visible from space. Satellite imagery shows the storm swallowing highways and buildings, and plunging the city of 2.6 million people into darkness.
