A long-running heatwave that has already broken records, sparked dozens of wildfires and left about 130 million people under a high-temperature threat is about to intensify enough that the National Weather Service has deemed it “potentially historic”.
The NWS on Saturday reported some type of extreme heat or advisory for nearly 133 million people across the nation – mostly in western states where the triple-digit heat, with temperatures 15F to 30F higher than average, is expected to last into next week.
Oppressive heat and humidity could team up to spike temperatures above 100F (about 38C) in parts of the Pacific north-west, the mid-Atlantic and the north-east, said Jacob Asherman, a meteorologist with the NWS.
Records were broken in at least four Oregon cities on Friday, the NWS reported. Medford, which had a high temperature of 102F set in 1926, saw temperatures soar to 109F. The biggest leap, however, was in North Bend, whose record of 74F set in 1913 was busted by a spike of 11 degrees when it hit 85F on Friday.
