Major Heat Wave Expected for Two-Thirds of the U.S.

A dangerous and widespread summer heat wave is expected through this upcoming weekend across much of the Central and Eastern U.S. A large dome of high pressure will allow high temperatures to surge into the 90s and 100s in many locations, while heat indices will top 100 and approach 110 degrees or higher. There also will be no relief at night, as low temperatures remain in the upper 70s and 80s. Read More >
