Arctic air moved into central and northeast South Dakota and remained for nearly a week. High temperatures from April 3rd to April 9th were mostly in the 20s to around 30 degrees with lows in the single digits and teens. The high temperatures were from 20 to 30 degrees below average, and the lows were from 10 to 25 degrees below normal across all of the area. Some record lows and many record low maximum temperatures were set throughout the period. The first ten days of April were the coldest on record for Aberdeen. The early spring cold period had an effect on many of the residents, especially farmers and ranchers, of central and northeast South Dakota. Also, many robins died from the cold and lack of food.
