More than half of the United States is steaming in heat blamed for six deaths that won’t let up until tonight. Four of the deaths took place in Maryland, where Baltimore’s thermometers hit 100 and high humidity made it feel like like 122. In Arkansas, former New York Giants offensive lineman Mitch Petrus, 32, died Thursday of heat stroke after working outside in 92-degree temperatures.
How bad is it? As U.S. temperatures are expected to ease off Monday, they’re forecast to soar in Europe. Across the Northern Hemisphere, July’s expected to be history’s hottest month.
