A high pressure system parking over the West is expected to bring temperatures this weekend and into next week that are extreme even for a region used to baking during the summer.
Notoriously hot Death Valley's forecast calls for 129 degrees, not far off the world record of 134 logged there July 10, 1913. The National Weather Service called for 118 in Phoenix, and at least 117 in Las Vegas on Sunday — a mark reached only twice in Sin City.
"It's brutal out there," said Leslie Carmine, spokeswoman for Catholic Charities, which runs a daytime shelter in Las Vegas to draw homeless people out of the heat and set them up with sunscreen and bottled water.
Meteorologists are calling for highs at or above 112 through Wednesday in Las Vegas, and there isn't even relief when the sun goes down. Sunday night's low is forecast to be 92 degrees — enough to make for a stuffy stroll down the Strip at whatever hour tourists leave the bar.
