Phoenix, Las Vegas, Denver and California’s Death Valley all posted record temperatures on Saturday, as dangerous heat swept across the American Southwest. The National Weather Service in Phoenix reported a temperature of 114 degrees Fahrenheit, tying the record high for the date set back in 1918. Las Vegas tied a record for the day set in 1956, with temperatures soaring to 109 F. The National Weather Service said there was a chance the high temperatures in both cities could rise even more. In Colorado, Denver hit 100 F, tying a record set in 2013 for both the high temperature and the earliest calendar day to reach 100 F. Temperatures in several inland areas of California reached triple digits by the afternoon, with a record high for June 11 of 122 F reached in Death Valley. Excessive heat warnings and heat advisories were issued for parts of Northern California through the Central Valley and down to the southeastern deserts. The National Weather Service also predicted 114 F in Palm Springs and temperatures around 100F across the San Joaquin Valley and the Sacramento area. Heat was expected to extend to inland portions of the San Francisco Bay Area but most of the California coastal zones remained free of heat advisories. The scorching heat in Northern California was expected to subside Saturday evening. Heat advisories in parts of Southern California were extended through Sunday.
