South Heat Wave to Break Records with Triple-Digit Temperatures
A persistent heat wave is gripping the southern United States, with temperatures soaring into the triple digits in states like Texas and Oklahoma. According to The Weather Company (2026-08-20), a heat dome is causing extreme heat and humidity, pushing heat indices above 105°F (40.5°C) and even 110°F (43.3°C) in areas such as southern Georgia, coastal South Carolina, the Florida Panhandle, and the mid-South region around Memphis. While some parts of the Southeast may experience slightly lower humidity this weekend, temperatures in cities like Tampa, New Orleans, Atlanta, and Raleigh are expected to remain high. Cooler and drier air from the Great Lakes is forecast to reach the interior Southeast by early next week, but the heat wave is expected to persist in Texas, Oklahoma, and Florida through much of the following week.
