'Wall of dust' engulfs Chicago as at least 23 are killed in tornado hellscap

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. The rare event shocked forecasters and locals after a dust storm warning was issued by the National Weather Service for only the second time in history.
