Meteorological events that happened on May 30th:

1879

John Park Finley of the U.S. Army Signal Corps was the first bonafide tornado researcher. In 1879, he was assigned the task of researching tornado events across the Plains of the United States. A major outbreak of severe weather occurred in Kansas and western Missouri. In Kansas, tornadoes killed 18 people at Delphos, and 30 people at Irving. Two tornadoes struck the town of Irving within a few minutes time virtually wiping the small Kansas community off the map. The second tornado was perhaps two miles wide, and exhibited multiple vortices. A local newspaper commented on Finley's investigation, stating its skepticism that studying such storms would be of little benefit to anyone who had gone through the storm or to anyone in the future. Indeed, Finley's work was met with skepticism in wide quarters. He set up a network of volunteer "tornado reporters" and even issued the first tornado forecasts. Finley's impressive research was pushed aside to be forgotten and he was reassigned to other duties.

1917

A tornado causing F4 damage killed 10 people and injured 100 in Crawford, Washington, St. Francois, and Jefferson counties in Missouri. This tornado was part of an outbreak that produced 7 separate tornadoes and was responsible for 21 deaths and 140 injuries.

1948

Vanport City was a federal housing project built during World War II on 650 acres along the banks of the Columbia River north of Portland, OR. Warm spring temperatures caused a rapid melt of the heavy snowpack in Columbia River basin. When a dike collapsed, it only took two hours to flood the entire city. There was almost no warning for the town's 19,000 residents and 25 people drowned. The residents of the town lost all of their personal belongings, most escaping with just the clothes on their backs. Vanport would never be rebuilt.

1961

Thunderstorms drop over 10 inches of rain in less than an hour in Buffalo Gap, Saskatchewan, Canada breaking a long drought.

1968

Severe flooding occurred in parts of New Jersey. Seven people died in the flooding between the 28th through this date. Damage totaled $133 million dollars.

1974

Severe thunderstorms produced winds of 57 mph or greater over parts of eastern Missouri. Hail measuring up to 2.75 inches in diameter was also reported in St. Charles County, Missouri and an F2 tornado caused $2.5 million dollars in damage in Adams County in Illinois.

1982

An amazing 17 inches of rain fell in a nine day period of time ending on this date at Avon, South Dakota. This led to major flood problems in the area. Krug's lake, located one mile south of Avon, is normally dry. Not only did the lake fill up, but it also drained into the south side of the town after a hastily constructed dike gave way. Many dwellings in the town ended up being completely surrounded by water.

1983

Unusually high temperatures throughout the western United States caused great runoff from snow pack in the Rocky Mountains. This caused flooding which washed out bridges and caused mudslides in parts of Nevada.

1985

An F3 tornado touched down west of Elkader, IA and tracked east northeast at about 45 mph. While the tornado did miss the town of Elkader, it did hit the County Care Facility and killed two residents. More than 20 farmsteads were also struck, with significant damage to dwellings, farm buildings, machinery, livestock, and crops. Total damage in Clayton County, IA alone was estimated at $9 million dollars including $1.5 million dollars at the care facility alone. The tornado crossed the Mississippi River near Bagley, WI. There were 25 injuries in Clayton County and two injuries in Grant County, Wisconsin. An F2 tornado caused over $100,000 worth of damage to area farms north of Livingston, WI.

Thunderstorms produced severe weather from the Upper Mississippi Valley to the Upper Ohio Valley during the day. A powerful F4 tornado injured three people and caused a million dollars damage at New Providence, IA. Baseball size hail was reported at Blue Earth, MN.

Many roads and several bridges were washed out eventually isolating the two towns. About 89 miles of road were damaged. Typical washouts ranged up to 8 feet deep and roads that were 25 feet wide were reduced to only 10 feet. Power outages were widespread and a state of emergency was declared. The flooding was the worst since 1955 for the area and total damage was estimated near $10 million dollars.

Baltimore, MD set a record high with 98° and Philadelphia, PA set a record May high of 97°.

1994

About 40,000 people obtain permits each year to climb dangerous Mount Hood, OR. On this date, a group of four climbers roped together was about 800 feet from the summit at a ledge called the "Pearly Gates," when a misstep by two climbers at the rear of the group pulled them all down and they slid into five other climbers. One by one, the climbers fell into a deep horizontal gash in the ice that forms each spring, many of them falling as much as 250 feet. Three climbers died.
