March 10, 2005:

High winds of 35 to 45 mph with gusts to near 70 mph occurred across all of central and northeast South Dakota from early morning to early evening. The high winds overturned a semi truck near Mound City; knocked a large branch down onto a pickup truck in Selby; blew a glass door off a store in Clark; tore a sign down in Aberdeen; and ripped the roof off a mobile home in South Shore.

March 10, 2009:

A strong low pressure system tracking across the panhandle of Oklahoma into the Great Lakes region produced moderate to heavy snow across west central Minnesota and across much of north central South Dakota from the morning of the 10th to the early morning of the 11th. Strong north to northwest winds gusting to 45 mph resulted in blizzard conditions. Travel became difficult, if not, impossible across the area. Interstate 29 between Watertown and the North Dakota border was closed for several hours. Several minor accidents occurred along with some injuries. Snowfall amounts included; 3 inches at Browns Valley, Milbank and Ortonville; 6 inches at Wheaton, Britton, Pollock, Roy Lake, and White Rock Dam; 7 inches in Eureka, Webster, Westport, and near Hosmer; 8 inches 6 miles southeast of McIntosh; 9 inches in Artas; and 10 inches in McLaughlin.
