Overview

Three mid-October winter storms impacted the region from Oct 19th through the 25th. Record cold accompanied this activity as well. 

The first system began late Monday night, October 19, through the day Tuesday, October 20. This system brought both heavy snow, rain and mixed precipitation to parts of the region. The heaviest snow fell over northeast South Dakota and west central Minnesota where several locations reported over 6 inches.

The second system developed late Wednesday night, October 21, through Thursday, October 22. This system brought heavy snow to parts of north central and northeast South Dakota, with a few locations reporting 12 or more inches.

The third system impacted much of central and east central South Dakota from Saturday, October 24th through the beginning of Sunday, October 25th. Up to a foot of snow fell across portions of central South Dakota, with enough wind for some drifting as well. 

It is rare to see this much snow so early in the season. Some locations even broke October snowfall total records. A number of cold low and high temperature records were set as well from the 19th through the 27th.
