Heat remains hot in the headlines across much of the nation.


What You Need To Know

  • The heat dome in the South continues to expand through the end of the week

  • Dangerously hot temperatures and heat index values will affect a good portion of the U.S.

  • Many places are at risk of seeing an uptick in heat-related illnesses 

Widespread Heat Advisories and Excessive Heat Warnings are now in effect for many across the Plains, Midwest and Northeast.

We're also seeing some heat alerts spread across the Southeast.

 

Highs will climb into the 80s and 90s for most, but the Plains will feel temperatures in the 100s.

The humidity will make it feel even hotter. Areas in the Excessive Heat Warnings will see heat index values up to 115, while other areas across the Plains, Midwest and Southeast could see heat indices up to 110.

The Northeast could feel heat indices in the low 100s.

The heat will peak on Friday before we see some relief for the Midwest and Northeast through the weekend. However, areas in the Southeast and Plains will continue to stay on the hotter side.

The combo of hot temperatures and high humidity will increase the threat of heat-related illnesses, such as heat exhaustion and heat stroke.

To stay safe, keep hydrated, avoid strenuous outdoor activities and stay in air-conditioned rooms or shaded areas during the peak heating hours of the day. Dressing in light, loose-fitting clothes will also help keep your body core temperature regulated.

In addition, keep a close eye on children, pets and older adults in the days ahead.
