If we can get them to go, this will provide the fuel for afternoon and evening thunderstorms with the risk for large hail and high winds. Storms will diminish late in the evening with a brief reprieve, before another round moves in from the west early Friday morning. Temperatures will dip into the 50s behind the cold front, with highs Friday from mid 80s in central South Dakota to mid 70s up in the Sisseton hills region, and noticeably lower humidity. $$ 07
