The record-breaking heat ushered in August Monday, with AccuWeather.com forecasters saying a dome of high pressure that cooked the nation during July will remain in place through at least the first week of the new month.
The National Weather Service said 2,676 daily record high temperatures were broken or tied in July across the United States, topping the total from last year's hot July by more than 1,200.
The hot, dry weather will extend the drought ravaging Texas and the southern Plains, AccuWeather.com meteorologist Brian Edwards said.
AccuWeather.com, based in Cincinnati, said the "bubble of heat" could begin to diminish toward the middle of the month, offering a chance that temperatures will be closer to normal.
