PHOENIX (AP) — A historic heat wave that has blasted the U.S. Southwest throughout July is showing signs of abating with late-arriving monsoon rains. Forecasters expect that by Monday, people in metro Phoenix will begin seeing high temperatures under 110 degrees for the first time in a month. But the National Weather Service says the high temperature in the desert city Saturday has still climbed past 110 for the 30th straight day. Chances of cooling monsoon thunderstorms are expected to increase Sunday. But wet weather also can bring damaging winds and flash flooding. Temperatures are also expected to ease in Las Vegas; Albuquerque, New Mexico, and even Death Valley, California.
