1969: During the afternoon of Friday, July 4, 1969, thunderstorms formed over southeast Lower Michigan (MI), several of which produced tornadoes, large hail, and high winds west and south of Detroit. As these storms moved southeastward during the early evening, they evolved into a strong derecho over extreme southeastern Michigan (MI) and Lake Erie (LE). The derecho then roared southeast across northern and eastern Ohio (OH) and Western Pennsylvania (PA) during the next few hours. The hourly positions of the gust front (associated with multiple bow echoes) are shown in Figure 1 (above). Winds gusted to 104 mph in Toledo (“T”), and reached 100 mph in the Cleveland (“C”) area. In towns and cities near Lake Erie, many people were outside, preparing to watch Independence Day fireworks. Also for the occasion, many small boat owners had anchored their craft just off the Lake Erie shore to watch the displays. As the derecho passed, untold thousands of trees were blown down, including 5000 in Toledo alone. Along the south side of Lake Erie, eight people were killed by falling trees, and over 100 boats were overturned, drowning at least three persons. A total of eighteen people were killed as a result of the derecho winds in Ohio. Some of the worst damage occurred in Lakewood, a suburb of Cleveland. The storm system continued to uproot trees, damage roofs and produce power outages as it moved into Pennsylvania, where high winds injured five people in Meadville (“M”).

1873: A tornado in Hancock County, in far west central Illinois, destroyed several farms. From a distance, witnesses initially thought the tornado was smoke from a fire. A child was killed after being carried 500 yards; 10 other people were injured. Click HERE for more information from Illinois Genealogy Trails.

2000:  There is a certain irony about one of the driest places getting the greatest rainfall, and yet that is what happened at usually rain-sparse Vanguard, Saskatchewan on July 3 when a carwash-like downpour flooded the community of 200 people, some 65 km southeast of Swift Current. As much as 375 mm (14.76”) of rain fell in eight hours, the greatest storm for that duration on the Canadian Prairies and one of the largest rainfall intensities ever recorded in Canada.

The spectacular thunderstorm produced more cloud-to-ground lightning strikes than that part of southern Saskatchewan would expect in two years. A year’s amount of rain left crops in the field drowning and rotting, and roads and rail lines under water. The force of the water crushed cars and farm implements swept away grain bins and soaked large bales. Stranded residents had to be rescued by boat, which rapidly became the carrier of choice on the main street in Vanguard. The flash flood also carried away herds of cattle and drowned dozens of deer and antelope. Some further irony, when millions of liters of contaminated water submerged the water-treatment plant and backed up into homes and businesses, officials had to ship in bottled water from Swift Current.

It crossed the outlet of Norton Pond and passed into Canada, and its path could be traced through the forests nearly to Connecticut River.”

The Derechos produced swaths of significant wind damage that extended intermittently from far eastern Nebraska through much of Iowa, northern Illinois, and southern Wisconsin into northern Indiana and southern Lower Michigan. The most continuous and intense damage occurred over eastern Iowa, northern Illinois, and northern Indiana, where some locations were affected by both derecho-producing storm systems. The Derechos also were responsible for widespread disruption of air travel through Chicago’s O’Hare International Airport. Click HERE for more information from the Storm Prediction Center.

1957: Hurricane Audrey moved northward, slowly strengthening until the 26th. At that time, a strong upper-level trough led to its acceleration and the hurricane deepened rapidly on its final approach to the Texas/Louisiana border. Audrey became the strongest hurricane on record for the month of June upon landfall, as it reached category four strength. Its acceleration was unanticipated, and despite hurricane warnings in place, 418 people perished in the storm, mainly across southwest Louisiana.
