Temperature records could be broken from northern Montana to southern California, as 56 million people are under excessive heat warnings as heat warnings.
“The historic heatwave in the West could last until Wednesday, as nearly 70 cities could set or bind records,” CNN meteorologist Gene Norman said.
A mountain of high pressure, a phenomenon associated with mostly sunny skies with hot weather, sits over the Western United States. It is not predicted to budget all week, so record-breaking heat may persist this weekend.
“Sunday’s 130 degrees at Death Valley could be sustained Monday,” Norman said. “The day started with a toasty low temperature of 107 degrees, and the forecast shows for 131 before noon. Once a 130 degree break is noticeable, doing it on back to back days would be great.”
Sacramento, California, saw its hottest August day on record Sunday, at 112 degrees. Los Angeles, Las Vegas, Seattle and Phoenix were also among cities that broke daily temperature records on Sunday.
Phoenix and Las Vegas expect a high temperature of 115 degrees every Monday, which would break Phoenix’s daily record. Salt Lake City will see highs above 100 degrees every day this week until Wednesday. All three cities are under excessive heat warnings until Wednesday night.
Canada is also feeling record heat
The extreme heat is also hitting Canada, as parts of British Columbia, Alberta and Saskatchewan are under warning. Half a dozen cities in Alberta set daily temperature records on Sunday.
Vancouver swells below its hottest streak of the year as temperatures climb to nearly 90 degrees Fahrenheit (32 degrees Celsius) on Sunday.
