Started today in Sterling and had a firm target of the Rapid City area. Storms today should easily initiate in an upslope flow regime near the Black Hills region. We got upto SW South Dakota in good time and watched towers start to explode to our North West near the Keystone and Mount Rushmore area. We headed North to be about 15 miles south of Rapid City and then followed and chased a beautiful little LP Supercell for the next few hours towards the Indian Reservations. Once again with such a high cloud base there was little chance of a Tornado today but what was on offer was some stunning High Based Supercell Structure. After chasing we ended the night in Sundance (Wy) and watched the line of storms roll in from SE Montana which also put us in a decent position for a chase in SE Montana the following day.
