“Heat could build through the middle to late part of August in the Northeast and Mid-Atlantic as many children return to school. This could be accompanied by high humidity and the risk of thunderstorm activity,” AccuWeather Meteorologist Brandon Buckingham said.
But the heat is still prevailing in the south
