Weather History - June 11th

June 11th, 1982:

Golf ball-sized hail fell in Hayti, in Hamlin County, creating three-foot hail drifts.

June 11th, 1990:

Golf ball-sized hail cut a swath 1.5 miles wide and 50 miles in length from the Missouri River east of the Hyde County line. Thunderstorm winds destroyed a granary roof and downed numerous trees. Damage from large hail was considerable to crops, and entire fields were wiped out. The County Agent placed crop damage estimates at 1.8 million dollars in Sully County. Hail also produced window damage to cars and homes.

June 11th, 2008:

A strong inflow of moist and unstable air into and over a warm surface front resulted in training thunderstorms and very heavy rain across parts of northeast South Dakota. Rainfall of 2 to 6 inches occurred across much of the area, resulting in widespread flash flooding. The flooding damaged many roads, bridges, and cropland. In Milbank, many basements were flooded and received sewer backup.

June 11th, 2010:

Thunderstorms produced damaging winds over a large part of southeast South Dakota, beginning just before midnight on June 10th and continuing well into the predawn hours of June 11th. The storms also produced heavy rain, which caused flash flooding at several locations. Heavy rainfall of at least 3 inches caused Enemy Creek to overflow and flood nearby roads. The expense also caused flooding of roads and basements in Mitchell. A motorcycle business was flooded, damaging merchandise, although little damage to the motorcycles was reported. Thunderstorm winds caused widespread damage in the Sioux Falls area. Wood and siding were blown off a new house, and a nearby fence was blown over. The winds caused tree damage, including 2 to 3-foot diameter trees blown down. Debris from the tree damage blocked several roads. Garages were blown off three homes next to each other, and other nearby homes suffered significant damage in an area on West Eli Court that was subjected to the strongest winds, estimated at 100 mph. Windows were blown out in several homes, and a large camper was overturned in the same area. A wind gust of 74 mph was measured elsewhere in the city. The winds blew down power lines in parts of the city. Heavy rain caused flash flooding of several streets in southern Sioux Falls, with water up to two feet deep. Basement flooding was also reported.
