Dangerous air quality and extreme heat will continue to challenge Memphis residents through Sunday, September 14, as late-summer conditions intensify. Health officials are advising sensitive groups—including children, seniors, and people with asthma—to avoid prolonged outdoor activity.
The Shelby County Health Department has issued a Code Orange Ozone Alert through Sunday, with ozone levels expected to exceed federal safety standards, posing risks for anyone spending extended time outdoors. The National Weather Service in Memphis also forecasts highs near 96°F, with heat index values approaching triple digits.
Travelers along Interstate 40 and major Memphis corridors should expect hazy skies and slower afternoon commutes as ozone concentrations peak. Outdoor events, such as youth sports and festivals, may see lower attendance due to safety concerns. Health officials recommend staying indoors during peak afternoon hours, keeping medications accessible, and limiting physical exertion outdoors.
Sunday will begin mostly sunny with highs climbing into the mid-90s. East winds will remain light, offering little relief from the stagnant conditions that worsen air quality. Overnight lows will stay in the low 70s, maintaining high humidity levels and adding stress for those without adequate cooling.
Relief is expected to be limited until midweek, when a modest drop in temperatures and clearer skies may return. In the meantime, Memphis residents are encouraged to monitor air quality at airnow.gov and check daily weather updates.
