Heat and humidity will expand across the region today and persist through the weekend. Areas from around Yankton into northwest Iowa will see the greatest impacts, with afternoon heat indices of 95 to 102 degrees expected for multiple days. The heat and humidity will contribute to increasing storm chances as the weekend progresses, with scattered strong to severe storms possible, especially later Saturday and again on Sunday into Sunday night. Locally heavy rain will also be possible.
Heat and humidity will return by the upcoming weekend. We’re projecting temperatures in the 90s, with heat index values approaching 100 degrees! Heat is the number 1 killer on average across the country. Please be sure to follow the Do’s and Don’ts for this upcoming heat wave.
Scattered strong to severe storms, along with the risk of locally heavy rain, will move into the region this weekend. Large hail looks to be a greater threat on Saturday evening/overnight and Sunday afternoon, while Sunday night could bring a greater risk of heavy rain. With the potential of nighttime storms, be sure you have a way to receive any possible warnings while you’re sleeping. If camping, be especially weather-aware and know the location of the nearest sturdy shelter.
