Great Blizzard of 1978
The Great Blizzard of 1978, also known as the Cleveland Superbomb, was a historic winter storm that struck the Ohio Valley and Great Lakes from Wednesday, January 25 through Friday, January 27, 1978. The 28.28 inches (958 millibars) barometric pressure measurement recorded in Cleveland, Ohio was the lowest non-tropical atmospheric pressure ever recorded in the mainland United States until the Upper Midwest Storm of October 26, 2010 (28.20" measured at 5:13PM CDT at Bigfork Municipal Airport, Bigfork, MN). The lowest central pressure for the 1978 blizzard was 28.05" (953 mb) measured in southern Ontario a few hours after the aforementioned record in Cleveland. 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").
Late on January 24 surface maps revealed a moisture laden Gulf Low developing over the southern United States while a separate, and unrelated low pressure system was present over the Upper Midwest. In about 24 hours, the merger of the subtropical jet stream (containing a wind max of 130 knots) and polar jet stream (containing a wind max of 110 knots) would lead the low pressure system to undergo bombogenesis as it moved rapidly northward during the evening of January 25 (record low pressures were logged across parts of the South and Mid-Atlantic). Bombogenesis events require a storm's central pressure to drop more than 24 millibars in 24 hours; the Great Blizzard deepened by a remarkable 40 millibars in that span of time.
As the storm headed for Ohio, this resulted in a "storm of unprecedented magnitude", according to the National Weather Service, which categorized it as a rare severe blizzard, the most severe grade of winter storm. Particularly hard hit were the states of Illinois, Indiana, Kentucky, Michigan, Ohio, and southeast Wisconsin where up to 40 inches (102 cm) of snow fell. Winds gusting up to 100 miles per hour (161 km/h) caused drifts that nearly buried some homes. Wind chill values reached −60 °F (−51 °C) across much of Ohio where 51 of the total 70 storm-related deaths occurred. The second lowest atmospheric pressure ever recorded in the United States, apart from a tropical system, occurred as the storm passed over Cleveland, Ohio. The barometer fell to 28.28 inches of mercury (958 mbar) on the morning of January 26. Nearby Detroit, Michigan fell to 28.34 inches of mercury (960 mbar).
The absolute low pressure with this storm was picked up at Sarnia, Ontario at around the same time, where the barometer bottomed out at 28.21 inches of mercury (955 mbar). Toronto fell to 28.40 inches, breaking the old record by 0.17. Canada did not escape the wrath of the storm as blizzard conditions were common across southwestern Ontario. London was paralyzed by 41 centimetres (16 in) of snow and winds gusting to 128 kilometres per hour (80 mph). The storm initially began as rain but quickly changed over to heavy snow during the pre-dawn hours (as arctic air deepened ahead of the storm) leading to frequent whiteouts and zero visibility during the day on Thursday, January 26.
The Blizzard was the worst in Ohio history where 51 people died as a result of the storm. Over 5000 members of the Ohio National Guard were called in to make numerous rescues. Police asked citizens who had four-wheel drive vehicles and snowmobiles to transport doctors to the hospital. From January 26 to 27, the entire Ohio Turnpike was shut down for the first time ever. The total effect on transportation in Ohio was described by Major General James C. Clem of the Ohio National Guard as comparable to a nuclear attack. Michigan Governor William Milliken declared a state of emergency and called out the Michigan National Guard to aid stranded motorists and road crews. The Michigan State Police pronounced Traverse City, Michigan "unofficially closed" and warned area residents to stay home. WTCM radio staffer Marty Spaulding, who closed the bayfront location station the previous night at 11 pm was called to re-open it the next day at 6am as regular staffers could not get there due to impassable roads. Upon arriving after a 45-minute walk in waist deep snow from his home a mere 10 city blocks distant, he had to dig down "a foot" to put the key in the front door.
In Indiana on day two, just a half-hour after the arctic front blasted through, the Indianapolis International Airport was closed due to whiteout conditions. At 3 am, the blizzard produced peak winds of 55 mph. Temperatures dropped to zero that morning. Wind chills remained a bone chilling 40 to 50 below zero nearly all day. The governor Otis R. (Doc) Bowen declared a snow emergency for the entire state the morning of the 26th. Snow drifts of 10 to 20 feet made travel virtually impossible, stranding an Amtrak train and thousands of vehicles and weary travelers. During the afternoon of the 26th, the Indiana State Police considered all Indiana roads closed.
Classes at the University of Notre Dame and the University of Michigan were canceled for the first time in the history of those universities, at Purdue University (where 25 inches of snow fell) for the third time in its history, and at Miami University (Ohio) for the first time since the assassination of President John F. Kennedy. An inch or more, usually much more, of snow would remain on much of that particular area for nearly two months straight. The storm did much damage to the Ohio valley and to the Great Lakes.
In Brampton, Ontario (northwest of Toronto) on Thursday afternoon, school buses could not get through deep snow to the then-rural campus of Sheridan College to take students home. Neither could any other vehicles, so some community college students had to stay on campus overnight.
|“||The most extensive and very nearly the most severe blizzard in Michigan history raged January 26, 1978 and into part of Friday January 27. About 20 people died as a direct or indirect result of the storm, most due to heart attacks or traffic accidents. At least one person died of exposure in a stranded automobile. Many were hospitalized for exposure, mostly from homes that lost power and heat. About 100,000 cars were abandoned on Michigan highways, most of them in the southeast part of the state.||”|
