A record dry month occurred for several locations across central and northeast South Dakota for September. Aberdeen, Pierre, and Mobridge all recorded their driest Septembers on record. Pierre recorded a trace of precipitation tying the old record of a trace in 1893. Aberdeen recorded 0.01 inches of precipitation breaking the old record of 0.05 inches of precipitation set in 1979. Mobridge recorded 0.05 inches of precipitation for September breaking the old record of 0.06 inches of precipitation set in 1969. Timber Lake and Wheaton both had their third driest Septembers on record with 0.05 inches and 0.12 inches, respectively. Sisseton had their fifth driest September on record with 0.17 inches. Watertown had their sixth driest with 0.29 inches while Kennebec had their 9^th driest September on record with 0.17 inches.   These amounts were from around an inch and a half to nearly three inches below normal. Thus, the drought expanded and worsened during the month of September as a result.
The average monthly temperatures for September ranged from near to around 2 degrees above normal across the region. The interesting fact on the temperatures was the wide range between the average highs and lows. The average highs across the region were much above normal ranging from 3 to around 6 degrees above normal for September while the lows were cooler than normal ranging from 1 to around 5 degrees below normal. The differences between the highest and lowest temperatures for the month were from 58 degrees at Wheaton to 76 degrees at Pierre. The reason for this wide range in day and nighttime temperatures is because of the dry soils. During the daytime, the ground warms up quickly due to the lack of moisture and in return radiates/loses heat quickly at night.
