February 19, 1986:

Snowfall of up to eight inches fell over parts of northeast South Dakota. Sisseton and Aberdeen reported 8 inches of snow with generally 2 to 5 inches falling over the area. Winds gusted to 35 mph and produced ground blizzard conditions at times. Many accidents were reported and several motorists were stranded. Roads were also blocked in many locations.

February 19, 2000:

Due to the extremely dry and windy conditions, a fire, believed to be started by a discarded cigarette, burned about 40 square miles of grassland between Kennebec and Lower Brule. The fire threatened a ranch but changed directions before anyone had to be evacuated.
