PHOENIX (AP) — The first heat wave of the season has arrived earlier than usual across much of the U.S. Southwest, with dangerously hot conditions that produced triple-digit temperatures on Tuesday.
Forecasters say temperatures are likely to top 110 degrees Fahrenheit (43.3 Celsius) in some areas by Thursday.
By Wednesday afternoon, much of an area stretching from southeast California to central Arizona will see “easily their hottest” weather since last September, and record daily highs will be in jeopardy from Las Vegas to Phoenix, the National Weather Service said.
