I was looking at South Dakota pretty seriously yesterday(6/9), and this morning(6/10) but, I could not quite do it. I watched a supercell near Sioux Falls on NexRad for a few minutes at a time over a several hour period from early morning. Around 2pm I decided to go after some of the cells forming from Western Minnesota along a line of about Renville, MN to Milbank, SD as I arrived the cells were training over the area from about Milan to Madison. The main threat was hail, high winds, flooding (and of course lightning) with most hail reports ranging in the .75 to 1.25 range with the odd 2.75 report, wind reports ranged in the 60-70mph range with other reports of trees down as well as some flooding. I took 212 West and started running into smaller non-severe cells in Renville County, and headed towards a couple of large cells crossing the river at Milan North of Montevideo, I then proceeded to Madison, making my way back to 212 staying in front of the nice shelf clouds the whole time. I toyed with the idea of some lightning shots but, most of the lightning was occuring within the widespread precipitation areas. Once I hit Renville I started making my way South as the line split and the Southern Cell appeared to be reving up but, gave that up SW of Olivia and started to make my way home once I could no longer see sunlight over the horizon.
