Dangerous Heat Wave Grips Southern U.S., Feels Like 115°F
A late summer heat wave has enveloped much of the United States, particularly affecting the Southern Plains and lower Mississippi Valley. According to the National Weather Service, over a dozen states are under heat advisories, with temperatures expected to soar to 100°F (37.8°C) or higher. Combined with high humidity, the heat index could reach a sweltering 115°F (46°C) in parts of the Southeast. This heat wave, caused by a high-pressure system trapping heat and humidity, is expected to persist through Wednesday. Nighttime temperatures are also forecasted to remain high, with lows staying in the 70s or even around 80°F (26.7°C) in urban areas. The extreme heat coincides with the start of the school year, raising concerns about student safety in classrooms, on buses, and during outdoor activities.
