Dangerous Scorching Heat

It will feel more like July than September for millions across the south-central U.S. as temperatures reach 10-20 degrees above average for five to seven days starting this weekend. Stifling heat will be felt in parts of the central and southern Plains and the lower Mississippi Valley. The sweltering temperatures could break records from Sunday to Tuesday as they climb to the 90s and 100s. Building heat and humidity combined with light winds and sunshine will make for dangerous conditions for people spending time outdoors. High school and college athletes could be particularly at risk, especially during practice sessions next week when the heat wave is going to peak. Steering winds will carry smoke from wildfires across the western U.S. to portions of the area in the coming days. Those in these areas will see a hazy appearance.

  • Severe pollution and extreme heat can contribute to air travel delays, shipment disruptions and trigger operational regulations.
  • Heat-related illnesses for those that work outdoors should be top of mind.
  • Plan for poor outdoor air quality to have a negative impact on job performance indoors and outdoors.
