Sioux Empire Braces For A Scorching Saturday Heat Advisory

Heat and humidity are back in the Sioux Empire to make everything gross and sweaty again this weekend

The National Weather Service (NWS) has issued a Heat Advisory for parts of South Dakota that includes Sioux Falls and areas south of I-90, for Saturday (August 15) afternoon and evening.

Hot temperatures will combine with rising humidity to create a heat index reaching 105 degrees. The super-hot conditions will make heat-related illnesses more likely.

"Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors." - NWS
