Great Blizzard of 1978

The Great Blizzard of 1978, also known as the White Hurricane, was a historic winter storm that struck the Ohio Valley and Great Lakes from Wednesday, January 25 through Friday, January 27, 1978. The barometric pressure measurement recorded in Mount Clemens, Michigan was the third lowest non-tropical atmospheric pressure recorded in the mainland United States and the lowest in the Central United States. The lowest confirmed pressure for a non-tropical system in the continental United States was set by a January 1913 Atlantic coast storm. The lowest central pressure for the 1978 blizzard was measured in Sarnia, Ontario, Canada. On rare occasions, extra-tropical cyclones with central pressures below 28 inches of mercury or about 95 kPa (950 mb) have been recorded in Wiscasset, Maine (27.9") and Newfoundland (27.76").
