Summer swelter trend: West gets hotter days, East hot nights

[admin]

As outlandish as the killer heat wave that struck the Pacific Northwest was, it fits into a decades-long pattern of uneven summer warming across the United States. The West is getting roasted by hotter summer days while the East Coast is getting swamped by hotter and stickier summer nights, an analysis of decades of U.S. summer weather data by The Associated Press shows. State-by-state average temperature trends from 1990 to 2020 show America’s summer swelter is increasing more in some of the places that just got baked with extreme heat over the past week: California, Nevada, New Mexico, Arizona, Utah, Oregon and Colorado.
