See the most extreme temperatures in South Dakota history

On July 9, 2021, California’s Death Valley reached 130 degrees Fahrenheit, according to an automated measuring system there, representing one of the highest temperatures ever recorded on the planet. The world record, also recorded at Death Valley, was 134 degrees in July 1913.

More than 210 degrees Fahrenheit separates the highest and the lowest temperatures on record in the United States, the third-largest country in the world. As some states are infamous for having blistering hot summers, others become inundated by winter storms and frigid cold. The contiguous U.S. had its warmest meteorological summer (June-August) on record in 2021, according to NOAA’s National Centers for Environmental Information.

Stacker consulted 2021 data from the NOAA's State Climate Extremes Committee (SCEC) to illustrate the hottest and coldest temperatures ever recorded in each state. Each slide also reveals the all-time highest 24-hour precipitation record and all-time highest 24-hour snowfall.

South Dakota by the numbers

- All-time highest temperature: 120° F (Fort Pierre 17 WSW on July 15, 2006)
- All-time lowest temperature: -58° F (McIntosh 6 SE on Feb.17, 1936)

- All-time highest 24-hour snowfall: 52 inches (Lead on March 14, 1973)

Record heat in 2006 resulted in the state's highest temperature in Fort Pierre, a city in Stanley County. The heat wave during July 2006 was so intense in South Dakota, Kansas, and Nebraska that it ended up disrupting transportation links and straining electric power grids.

Iowa by the numbers

- All-time highest temperature: 118° F (Keokuk No 2 on July 20, 1934)
- All-time lowest temperature: -47° F (Elkader 6 SSW on Feb. 3, 1996)

The Nishnabotna River that runs along Atlantic in Iowa's Cass County experienced intense flooding on June 14, 1998, after heavy rainfall and a severe thunderstorm. Many bridges were either damaged or completely destroyed, and all highways and roads had to be closed once the flooding started intensifying. More recently, in October 2020, western Iowa suffered from repeated flooding that forced the closure of Interstate 29 and Interstate 680.

Minnesota by the numbers

- All-time highest temperature: 115° F (Beardsley on July 29, 1917)
- All-time lowest temperature: -60° F (Tower 2S on Feb. 2, 1996)

- All-time highest 24-hour snowfall: 36 inches (Wolf Ridge Environmental Learning Center on Jan.7, 1994)

Hokah, a city in Houston County, had the state's heaviest one-day rainfall on Aug. 19, 2007. The flood of 2007 claimed the lives of six people and resulted in nearby counties also going several feet underwater.
