Parts of Siouxland are under a heat advisory until six tonight. The heat index will climb easily into the triple digits. According to the National Weather Service, there is a chance for severe storms with hail and high wind. Plus, areas south of Yankton to Spencer will have an elevated risk for a brief tornado.
Due to the heat, Hunt Elementary school will have an early dismissal. While a new school is being built, students are attending class in the old Crescent Park building. It is the only non-air conditioned school in the district.
