 temperatures mid to upper 90s, and the heat index as high as 107 in a few spots, that high humidity will increase the risk for heat-related illnesses to occur. That does include heat stroke, which can be fatal. Heat is the number one weather-related killer each year in the United States, more than hurricanes, tornadoes, and floods. So keep that in mind. Lots of water, shade, sunscreen, and limit your time outside during the afternoon.
