It's not your imagination, folks -- it really is that bad. From Weather Underground's Bob Henson,
The steamy, fiery summer of 2017 hit a new crescendo this weekend across the U.S. West, which is getting its hottest Labor Day weekend on record in many locations—and in some spots, the hottest weather ever observed. Overall, "this is the greatest statewide heat wave ever recorded in California,” proclaimed WU weather historian Christopher Burt on Saturday night. Burt based his conclusion not only on the heat’s intensity but on its widespread nature well beyond California’s usual scorching locations. Even an escape to the cool Pacific shore was pretty much futile, as easterly downslope winds funneled scorching air from the interior into coastal sections that are normally mild and sometimes chilly even in midsummer. Readings also soared above 110°F across California’s Central Valley, although such heat is not quite so unusual for late summer in that area.
California’s Bay Area has been the focal point of the weekend’s most extraordinary heat. Temperatures soared to 106°F in downtown San Francisco on Friday and 102°F on Saturday. Friday’s reading was the hottest ever measured in downtown SF, where temperatures have been observed since 1874. Friday’s 106°F handily topped the previous record of 103°F from June 14, 2000, and Saturday was only the second high of 102°F in downtown history, matching Oct. 5, 1987. “To put this in perspective, the average high temperature for the city these two days is just 71°F,” said Chris Burt, who lives in the East Bay region. “Friday night’s temperatures failed to fall below 85°F at several hill locations near me (I dropped to 81°).” He added: “It is so hot in our home I can hardly think. No air conditioning, of course.” Heat-related illnesses overwhelmed San Francisco hospitals on Friday, according to the Bay Area NWS office. It would not be shocking to see multiple Bay Area fatalities during this heat wave, given the multi-day intensity of the heat and the Bay Area’s lack of air conditioning.
It's almost as if we'd reached some kind of tipping point. If only we had someone like Hillary Clinton in charge.
