NOAA wrote:Since South Dakota is situated in the heart of the North American Continent, it is near the paths of many cyclones and anticyclones, and has the extreme of summer heat and winter cold that are characteristic of continental climates. The highest temperature of record in the State is 120 degrees Fahrenheit (° F) observed July 5, 1936, at Gannvalley; the lowest, -58° F, February 17, 1936, at McIntosh. Rapid fluctuations in temperature are common. Partly because of the great distance from any large body of water, the ranges of daily, monthly and annual temperatures are very large. Temperatures of 100° F or higher, are experienced in some part of the State each year, and on rare occasions such readings have been noted as early as April and as late as October. These high temperatures are usually attended by low humidity, which greatly reduces the oppressiveness of the heat. Subzero temperatures occur frequently on mid-winter mornings, but it is not often that the temperature stays subzero during the entire day. In the north, subzero temperatures can occur between October and April.
