(CNN) -- A series of cities are in the grip of soaring temperatures this weekend. From Phoenix, to Las Vegas, to Death Valley in California, which set a world-record high a century ago. Death Valley was the hottest spot Saturday, reaching 127 degrees, and Arizona and Nevada continued in a record-setting heat wave that is forecast to last through Tuesday. The heat may have led to the death of a man in his 80s in Las Vegas, where the temperature Saturday hit 115 degrees, tying a record set in 1994, the National Weather Service said. Paramedics found the man dead in his home, which did not have air conditioning, said Las Vegas Fire & Rescue spokesman Tim Szymanski.
