WX History: July 14th

1995: On the evening of Friday, July 14th, thunderstorms producing severe weather were occurring over Upper Michigan and adjacent portions of Ontario near Sault Saint Marie. By late evening the storms had evolved into a bowing line just northwest of the Mackinac Bridge. At 10:17 PM EDT, the thunderstorm gust front hit the bridge, and a gust of 90 mph was measured. Sustained winds of 80 mph continued on the bridge for ten more minutes. Thus began the intense “Ontario-Adirondacks Derecho” that would cause hundreds of millions of dollars’ worth of damage, several deaths, and many injuries as it raced southeast from the northern Great Lakes to the Atlantic coast.

Temperatures across the region reached as high as 104 degrees, overnight lows on falling to the upper 70s to low 80s.

1996: Hurricane Bertha makes landfall near Wrightsville Beach, NC with maximum winds of 105 mph, but the storm surge dealt the most devastation. The U.S. Virgin Islands, along with North Carolina, were declared federal disaster areas. Surveys indicate that Bertha damaged almost 2,500 homes on St. Thomas and St. John. For many, it was the second hit in the ten months since Hurricane Marilyn devastated the same area. The primary effects in North Carolina were to the coastal counties and included storm surge flooding and beach erosion, roof damage, piers washed away, fallen trees and damage to crops. Over 5,000 homes were damaged, mostly from storm surge. Storm total rainfall amounts ranged from 5 to 8 inches along a coastal strip from South Carolina to Maine. Overall, as many as 12 deaths resulted with 8 in the U.S. and territories. Click HERE for more information from the NWS Office in Morehead, North Carolina.Hurricane Bertha, 1996 2

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.

1944: On this date, six estimated F2 or greater tornadoes were tracked across northeast South Dakota and west central Minnesota. The first tornado touched down at approximately 3:30 pm CST in Faulk County. This estimated F2 tornado destroyed all buildings except the house on a farm 7 miles northeast of Faulkton. The next tornado occurred at 4:00 pm CST in Codington County, where barns were destroyed. Cattle and a truck were thrown into Grass Lake, near Wallace. About the same time, in Brown County, a tornado moved northeast from just northeast of Warner and crossed the town of Bath. This storm killed two people and injured another twelve. A couple was killed in the destruction of their home. Twenty homes in Bath were damaged. A brick school had its upper story torn off. Another tornado moved through Codington County at 4:45 pm CST, killing three and injuring twenty-five. This F4 strength tornado moved northeast from two miles northeast of Henry, passing over Long Lake and ending 2 miles northwest of Florence. The funnel was described as snake-like over Long Lake and massive as it swept through five farms southwest of Florence. Over 100 head of cattle were killed, and about a dozen homes were destroyed.

This outbreak produced the greatest number of tornadoes rated EF4 or higher in one day in Minnesota since the Black Sunday tornado outbreak on April 30, 1967. This was the first EF4 tornado in Freeborn County since the Black Sunday outbreak The four total EF4 tornadoes across the Upper Midwest on June 17, 2010 (3 in MN, and 1 in ND) were the most in any outbreak in the U.S. since the “Super Tuesday Outbreak” on February 5-6, 2008.

1972: A look back at Hurricane Agnes.

1991: The second largest volcanic eruption of the 20th Century began as Mt. Pinatubo injected 15 to 30 million tons of sulfur dioxide 100,000 feet into the atmosphere. 343 people were killed in the Philippines as a result of the eruptions, and 200,000 were left homeless. Material from the eruption would spread around the globe, leading to climate changes worldwide as the sun’s energy was blocked out and global temperatures cooled by as much as one degree Fahrenheit. 1992 was globally one of the coldest since the 1970s.

2017: A very tall waterspout spun up on Mobile Bay Thursday morning as thunderstorms moved southeast into the Gulf of Mexico.

1953: The deadliest tornado in Michigan history struck the northern Flint community of Beecher, killing 116 and injuring 844 along its path. This F5 tornado would be the last single tornado to result in 100 or more fatalities until Joplin in 2011. Continued research in severe convective storms, improving technology, and the establishment of an NWS center dedicated to severe weather forecasting all contributed to reduction in fatalities over the past 6 decades.

1966: A tornado ripped right through the heart of the capital city of Topeka, KS killing sixteen persons and causing 100 million dollars damage. The F5 tornado, which struck during the evening, cut a swath of near total destruction eight miles long and four blocks wide. Television station WIBW covered a tornado live, dispatching crews to the southwest of Topeka, KS when the tornado warning was issued. Newscaster Bill Kurtis would be lauded for sounding the alarm with urgent warnings as the tornado cut a path across the city. The death toll would certainly have been higher without the station’s coverage. It was the most destructive tornado of record up until that time.

1984: Early in the morning hours of June 8, 1984, a series of tornadoes affected portions of Southern Wisconsin. A number of these tornadoes were strong to violent, causing significant damage. The most notable tornado was the one that struck the town of Barneveld, Wisconsin in Iowa County shortly before 1 AM. About 90 percent of the town of Barneveld was destroyed. 93 homes were destroyed, and 64 were damaged. Seventeen of eighteen businesses and public buildings in the village were destroyed. This tornado was rated an F5 on the Fujita Scale for tornado intensity. An F5 is the highest rating that a tornado can achieve, and this particular tornado was given an F5 rating because of the severity of the damage caused to relatively new construction homes in Barneveld

1995: A tornado cut through the west side of Pampa TX (northeast of Amarillo), resulting in F4 rated damage.

2001: Tropical Storm Allison hits Houston, Texas, for the second time in three days. Louisiana and southern Texas were inundated with rain. Baton Rouge received 18 inches over just a couple of days. Some portions of Texas racked up 36 inches by June 11.
