WASHINGTON (AP) — Dangerously hot weather will expand across much of the central United States this weekend and into next week, pushing temperatures above 100 degrees Fahrenheit (37.8 degrees Celsius) from Dallas to North Dakota with roughly 70 million people facing heat advisories.A heat dome, where atmospheric conditions trap heat, will create sustained high temperatures and accumulating discomfort. Overnight low temperatures aren’t expected to come down enough for people to have much chance to recover, allowing heat stress to build as the bad weather lingers, forecasters said. The high humidity will make it feel even worse.A huge stretch of the country will endure the oppressive midsummer weather. It will stretch from the desert Southwest to the Gulf Coast, reaching up into the Midwest and Great Plains. Some records around the Denver area may be broken, forecasters said. Temperatures are expected to be 10 F to 15 F (5.6 to 8.3 C) above what’s normal.
“It looks like it is going to be pretty much stationary in that position as we go through the week,” said Bob Oravec, meteorologist with the National Weather Service. There might be some relief in the central United States toward next weekend, but even that might be temporary, he said.
