With areas of southeast KELOLAND now eight to nine inches below precipitation for the year, it is helping the dry ground to easily cool at night due to the lack of moisture.
Even though we started warm this month, the combination of frequent cold fronts from the north and dry ground have allowed temperatures to be below average so far this month.
This is similar to what happened in 1976. That summer is now our third driest summer in Sioux Falls, but it's also our sixth driest autumn.
During October and November of that year, temperatures were below average. The below average temps actually lasted through January, when the average low in January was seven below.
Precipitation also remained below average during that time, but as the temperatures warmed above average in February and March, the precipitation also went above average.
We'll see if we follow that trend this year.
