Hot and humid air with highs in the 90s and dewpoints around 70 degrees set up across central and eastern South Dakota during the day Friday. This was just ahead of a front that was slowly migrating southeast, though the frontal passage brought little relief as temperatures on the north side of the front still topped out close to the century mark, with dewpoints remaining in the 60s. Morning lows both Friday and Saturday remained in the 70s for most of the area. A peak heat index value of 120 degrees was observed at weather stations in Mellette and Onaka, with over 70 weather stations in central, north central and northeast South Dakota reporting a heat index of 100 degrees or higher at some point during the day.
