Temperatures reached as high as 98 degrees Fahrenheit (36.7°C) by midday in Washington, DC and New York City, though it felt more like 110 degrees F (43.3°C) with the humidity, according to the National Weather Service.
The heat wave is due to break on Monday in a burst of thunderstorms and cooling rain brought on by a cold front, the National Weather Service said.
On Saturday (July 20), new one-day temperature records were recorded in at least half a dozen places, including a high of 99 F (37.2°C) at New York’s John F. Kennedy International Airport and a high of 97 F (36.1°C) at Detroit Metropolitan Airport.
In New York, the streets were unusually empty, and anyone outside was doing their best to keep cool with children running through park fountains and open fire hydrants.
In Washington, dozens of people beat the heat by indulging at a National Ice Cream Day event while others took to local water parks and swimming pools.
