Louisville, Kentucky – Dangerously high temperatures will grip the Ohio Valley and parts of the Southeast through Friday, with the most extreme heat centered over Kentucky, southern Indiana, and southern Ohio.
According to the National Weather Service, Excessive Heat Warnings and Heat Advisories remain in effect across much of the region, including cities like Louisville, Cincinnati, and Nashville. Friday marks the final day of the most intense heat, with “Extreme” level risk (Level 4 of 4) concentrated along the I-64 and I-75 corridors. Temperatures could feel like 105°F to 110°F during peak afternoon hours.
By Saturday, the worst heat will ease slightly, with highs returning to the 80s and lower 90s. Areas like St. Louis, Evansville, and Lexington are expected to fall into the “Moderate” to “Major” heat risk category, while cities in West Virginia and western Pennsylvania should feel notable relief.
The NWS urges residents to stay hydrated, limit outdoor activity, and check on vulnerable populations. Heat-related illnesses spike during prolonged events like this. Anyone without access to air conditioning is at heightened risk for heat stroke and exhaustion.
Heat advisories expire Friday night, but weekend updates may follow if risks linger for some areas.
