Nashville, Tennessee – A dangerous and persistent heat wave is intensifying across Tennessee, sending heat indices soaring above 110 degrees and prompting major safety concerns for residents through Wednesday.
According to the National Weather Service, this long-duration event brings “extreme” heat risk to the state, especially from Memphis to the Cumberland Plateau. Temperatures in the upper 90s, combined with stifling humidity, will make it feel like 110-115° in many communities, with little overnight relief as lows remain in the upper 70s. High risk zones include Nashville, Memphis, Knoxville, and Chattanooga, where emergency agencies urge residents to stay indoors and avoid strenuous activity.
The heat is expected to impact daily life across Tennessee, with school districts monitoring conditions for potential delays, while road crews and power companies brace for increased demand and potential outages. Interstates I-40, I-24, and I-65 could see pavement buckling and slowdowns due to the extreme heat. Vulnerable groups—such as children, seniors, and those without air conditioning—face the greatest risk. Authorities recommend staying hydrated, limiting outdoor activity, checking on neighbors, and seeking out local cooling centers.
This heat wave is one of the most severe July events in recent years and is likely to continue through at least the middle of next week. Further advisories and possible alerts are expected if conditions worsen.
