Most of the eastern and central regions of South Dakota are under some type of heat alert, as temperatures are expected to be over 100 degrees by Sunday afternoon.
The combination of dewpoints into the mid-70s and air temperatures into the 90s will create dangerously hot conditions.
Remember to drink fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Do not leave young children and pets in unattended vehicles. Car interiors can reach lethal temperatures in minutes.
Take extra precautions when outside. Wear lightweight and loose-fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke.
To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air-conditioned environments.

Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency, and those who come across it should contact emergency personnel quickly.
A front will push this heat and humidity out of the region on Monday and into Tuesday. This will create a likely chance for strong to severe thunderstorms to develop over the area.
