A punishing heat wave will bring hot temperatures to eastern US and linger for several days, underscoring how climate change heats things up.

The soupy, smothering extreme heat that has scorched parts of the Northern Hemisphere this summer takes a hard toll on our bodies. It can make you feel nauseous, woozy and dehydrated. It can have pernicious health effects on multiple organs. But there’s another, less well-known, impact of extreme heat: It makes you age faster.

Widespread showers and storms are likely to develop between 3 p.m. and 5 p.m., moving west to east. Tropical downpours with several inches of rain are possible under any thunderstorms, leading to localized flash flooding. There is also a lower-end severe weather threat with any storm, including damaging winds and large hail.

The National Weather Service released an updated extreme heat warning at 12:53 p.m. on Friday in effect until 9 p.m. for Eastern Montgomery and Lower Bucks as well as Delaware and Philadelphia counties.

Sauna-like conditions on Friday are threatening to break records in major Northeast cities during summer’s hottest month after dangerous heat peaked Thursday in the central United States.

At 1:44 a.m. EDT on Sunday, the National Weather Service issued a heat advisory valid between noon EDT and 9 p.m. EDT for Cass, St. Joseph, Branch, Hillsdale and Berrien counties.

The heat, combined with the high moisture content, is causing the heat index values to reach up to 107 degrees on Saturday afternoon.

"Preventing heatstroke in dogs requires several proactive measures," Dr. Rebecca Tremble, a veterinarian, told Newsweek.
