Wyoming, Colorado Snow in June, 1947

Since 1883, Cheyenne Wyoming has seen more than a trace of snow 16 times during the month of June. The most recent June snowfall occurred on the 4th and 5th, 1998. The total snowfall amount on these two days was 0.7 inches. The most snowfall in June took place on the 11th and 12th, 1947 when 8.7 inches fell. This late snowstorm caused significant losses to livestock. One rancher in the Cheyenne area reported a loss of approximately $15,000 in livestock. In Natrona County, losses were estimated at $125,000 with most confined to newly shorn sheep and young lambs.

Corn, Oklahoma Tornado June 8, 1951

During the evening hours on Friday, June 8th, 1951, the small town of Corn, Oklahoma was visited by a devastating, F4 tornado. This massive tornado destroyed homes and several farm buildings on its 15-mile east-southeastward track across Corn and Colony, Oklahoma. The storm killed over 26 head of cattle and 1,000 chickens. Debris was reportedly carried as far as 90 miles away.

Another tornado, not of the track map above, moved eastward from 6 miles west of Corn. Some observers claim to see the two tornadoes merge before going into town. The Western History Collection at the University of Oklahoma Library has a picture of these two tornadoes. 

The twin twisters are rare by today’s standards, just imagine trying to photograph one in 1951! More incredible, this tornado was caught on 16 mm film. John Gossen, who lived 6 miles south of Corn, grabbed his motion picture camera and became the first person in the US to capture a tornado on motion pictures.

Tropical Storm Allison – June 4 – 18, 2001

Tropical Storm Allison brought intensive rainfall to the Gulf of Mexico states of Texas, Louisiana, and Mississippi. The first storm of the 2001 Atlantic hurricane season, Allison lasted an unusually long time, remaining a tropical or subtropical storm for 15 days. Allison reached Tropical Storm strength at 1200 UTC on June 5 with peak winds of 60 mph. Later in the day, Allison made landfall near Galveston, Texas with peak winds of 50 mph. Inland, the storm rapidly weakened with the National Hurricane Center discontinuing advisories early on June 6. From the NOAA Service Assessment, “Allison drifted back into the Gulf of Mexico on June 9, turned to the northeast, and made landfall again on June 10 near Morgan City, Louisiana. After causing 24 deaths in Texas and Louisiana, Allison moved across southern Mississippi, southern Alabama, southwest Georgia, and northern Florida, causing nine more deaths.”

Tropical Storm Allison caused more damage than any tropical storm in U.S. history, with estimates more than $5 billion. Because of this, the name Allison was retired from being used by the National Hurricane Center. Allison became the only Atlantic tropical storm to have its name retired without reaching hurricane strength. In 2015, Tropical Storm Erika joined this exclusive list.

Most of the damage and fatalities (22) occurred in Houston, Texas.

In Louisiana, Allison ranks among the worst storms to hit the state in the past 100 years. The most significant flooding occurred on June 6-7. Much of the city of Thibodaux was flooded when 15.16 inches of rain fell in 24 hours. In East Baton Rouge Parish, flooding resulted in the evacuation of 1,800 residents and flooded 1,000 homes. Over 2,000 homes were flooded in Livingston, Lafourche, St. Tammany, and Ascension Parishes.

“By mid-week, Allison stalled over North Carolina and produced more heavy rainfall and flooding before tracking northeast along the DelMarVa Peninsula and moving off the New England coast on June 18. Seven additional deaths occurred in Pennsylvania and one in Virginia.”

Within weeks of this storm, 75 counties in Texas, southern Louisiana, southern Mississippi, northwest Florida, and southeastern Pennsylvania were declared disaster areas by President George Bush.

Gainesville, Georgia Tornado of June 1, 1903

During the early afternoon, one of the most destructive tornadoes in the history of Georgia, up to this time, struck the outskirts of Gainesville. The track of the storm was about four miles in length and varied between 100 to 200 feet in width. The tornado touched down about one mile southwest of Gainesville, striking a large cotton mill at 12:45 pm, Eastern Time, just 10 minutes after 750 employees filed into the great structure from dinner. On the top floor of the mill were employed 250 children, and it was here that the greatest loss of life occurred. This estimated F4 tornado killed 104 people and injured at least 200 others.
