We ended up in central South Dakota this day on what appeared to be a pretty marginal situation. Nonetheless a tornado watch was issued for the dryline in South Dakota, down through northern Nebraska. We positioned ourselves near Presho and watched a high based supercell spin like crazy and eventually produce this brief 2-3 minute weak tornado. It also produced an amazing cg display and dumped golf ball sized hail on us. Freakiest thing this day was what happened on the way to our hotel east near Chamberlain. As we were going down into the Missouri river valley, a freak gust of wind from a decaying storm hit us with such force, it picked up pebbles from the side of the road and blew out all the windows on the drivers side. Other than being shaken up a bit and a couple glass cuts, everyone was fine. Later we found out others had also been hit by this strange wind gust. This put us out of commission the next day as we had to get glass installed. Caryn and her on call group witnessed a tornado near Harrison, NE on that day.
