  • A dangerous heat dome is expanding across much of the central United States, threatening approximately 70 million people with temperatures above 37.8°C (100°F).
  • The atmospheric conditions will trap heat, leading to sustained high temperatures and minimal overnight cooling, increasing heat stress.
  • The extreme heat is expected to persist for days, with some areas potentially breaking records, while other regions like the Mid-Atlantic and Northeast may see some relief.

A dangerous heat dome is expanding across the central United States, putting an estimated 70 million people at risk of extreme temperatures exceeding 37.8°C (100°F). The oppressive weather system, characterized by atmospheric conditions trapping heat, is set to bring sustained high temperatures and significant discomfort throughout the weekend and into the coming week.

Forecasters warn that minimal overnight cooling will prevent adequate recovery, allowing heat stress to accumulate. High humidity levels are expected to exacerbate the feeling of heat. The sweltering conditions will stretch from the Southwest desert to the Gulf Coast and reach into the north-central region and the Great Plains. Record-breaking temperatures are possible in the vicinity of Denver, with readings projected to be 5.6°C to 8.3°C above normal.

It looks like it's going to remain pretty much stationary in that position as we go through the week.

— Bob OravecA meteorologist with the National Weather Service described the expected duration of the heat dome.

"It looks like it's going to remain pretty much stationary in that position as we go through the week," said Bob Oravec, a meteorologist with the National Weather Service. In western Nebraska, temperatures were forecast to reach 42°C on Saturday and Sunday. At the Museum of the Fur Trade near Chadron, Nebraska, an employee noted fewer visitors than usual, with fur hats and pelts not selling well. "I'm sure nobody would want to put it on in a day like this," said Hannah Lovelace, a museum employee.

The heat is predicted to continue through the week in the region, with temperatures remaining above 37°C even in typically moderate areas of Montana and Wyoming. While some relief might arrive in the central U.S. by the following weekend, it could be temporary. The Mid-Atlantic, Northeast, and much of the Pacific Northwest are not expected to experience the extreme heat. This latest heatwave follows a summer already marked by intense heat, which led to the cancellation of Independence Day celebrations in the eastern U.S. and disrupted the country's 250th-anniversary events.

I'm sure nobody would want to put it on in a day like this.

— Hannah LovelaceA museum employee in Nebraska commented on the lack of sales for heavy clothing due to the extreme heat.
