Sioux Falls Starting Week With an Excessive Heat Watch
The Sioux Falls area could see temperatures into the 100s this week. That combined with humid conditions has prompted the National Weather Service to issue an Excessive Heat Watch for much of eastern South Dakota including Sioux Falls Monday afternoon through Wednesday Evening (August 20-22, 2023).
"Extreme heat and humidity will significantly increase the potential for heat-related illnesses, particularly for those working or participating in outdoor activities," The National Weather Service says.
"Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances."
