Record snowfall in South Dakota – Almost double previous record

Record snowfall in South Dakota – Almost double previous record:

The Yankton region saw nearly two feet (60 cm) of snow in some areas, almost double the previous record.

The city itself recorded 8 inches of snowfall, while a site to the east-southeast of town recorded about a foot of snow. Yankton’s record snowfall for Nov. 20 stood at 12 inches, set in 1975.

South Dakota state climatologist Dennis Todey said he was waiting to talk with National Weather Service (NWS) officials for more details on the unexpected brunt of last Friday’s storm. Early forecasts for snow totals were lower.

“There was a fairly large ‘under forecast’ of snow. That’s not common,” he said. “This was quite large in any context for the snow. There was a report from Marion around 16 inches. That would make for their second largest snow total ever. Sioux Falls officially will come in the top 10 (for) November one-day totals.”

Tea and Harrisburg recorded a respective 18 and 17 inches, followed by Alcester and Marion with 16 inches each.

Other snowfall totals include Centerville with 12.5 inches, Wakonda 12 inches, Tripp and Tyndall 11 inches, Vermillion 9 inches; Menno, Armour and Ponca, Nebraska, 8 inches each; and Corsica and North Sioux City 7 inches each.
