After days of record temperatures, the U.S. is no closer to beating the heat. Soaring temperatures are still spreading eastward, meteorologists say, and heat advisories will be in place down the Eastern Seaboard throughout the weekend. Already, almost half the U.S. population has been affected, and 22 deaths have been attributed to the heat wave. On Tuesday, heat indices hit 129 in Newton, Iowa, and 123 in Hutchinson, Minnesota. Temperatures in the East, which the National Weather Service said it felt like between 100 and 110 degrees on Wednesday, with temperatures set to get even hotter on Thursday and Friday.
