The heat and the humidity will return today. High temps will reach the 90s with heat index values soaring to the mid to upper 90s this afternoon.

Scattered showers and thunderstorms will develop across central and northern South Dakota later today and move east this evening and overnight. While thunderstorms will not be widespread, those that do develop will have the potential to become severe. Hail and straight-line wind gusts will be the main threat.

The rest of the weekend will be slightly cooler with scattered showers and thunderstorms possible on both Saturday and Sunday.
