A heatwave impacting over 120 million Americans across 28 states is expected to ease in the Northeast starting Thursday. Areas like St. Louis will see temperatures drop to the 70s, while Philadelphia and Boston will reach near 70 degrees by Friday. However, the South will continue to experience extreme heat, with high temperatures and humidity persisting throughout the weekend, particularly along the Gulf Coast and potentially a new heat dome forming in the Southwest.
