Parts of California, Nevada and Arizona are expected to bake this week as the first heat wave of the season arrives with triple-digit temperatures forecast for areas including Phoenix, which last summer saw a record 31 straight days of at least 110 degrees Fahrenheit (43.3 Celsius).
By Wednesday, most 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 late Monday.
