Chicago's benchmark blizzard of '67

Nor-easter bears down on Northeast on 48th anniversary of Chicago’s benchmark Blizzard of ’67

48 years ago today was the largest snowstorm in Chicago history. As the northeast bunkers down and prepares for a snow storm that could bring up to three feet of snow to the region. This storm just barely nicked Chicago and the Chicagoland area, but will gain strength as it moves farther east. The storm of '67 stranded over a thousand cars and 1100 CTA buses. By the time the snow stopped falling, 23' of precipitation had fallen.
