Summary:
A warm and humid airmass, combined with a frontal boundary draped across the area led to the formation of several supercell thunderstorms over sections of central South Dakota on 16 June 2009. Multiple reports of funnel clouds were relayed to the NWS in Aberdeen, and there were several confirmed tornado touchdowns. Due to the abundant moisture, many of the tornadoes likely became "rain wrapped" which prevented spotters from seeing additional funnel clouds or tornadoes. Two of the more distinct tornadoes are shown below -- one from Corson County (near McLaughlin) and a second from far southeastern Hand County. All of the tornadoes that developed on Tuesday, including the two shown below, were rather brief lasting only a few minutes. No damage was reported from any of the confirmed tornadoes.

Photo 3: Tornado near the intersection of 213th and 370th Avenue in Hand County around 400pm CDT. The tornado was on the ground for approximately 10 to 12 minutes and remained nearly stationary. As shown in the photo, the tornado remained primarity over a CRP field and thus there was no damage reported. Photo courtesy of Hand County Sheriff.
Photo 4: Photograph taken near the intersection of 205th and 369th Avenue in Hand County around 350pm CDT. The Hand County Sheriff was located a few miles north of the storm. This is likely the "rear flank downdraft" of the supercell storm. Photo courtesy of Hand County Sheriff.
