"PHOENIX — 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.
Excessive heat warnings were issued for Wednesday morning through Friday evening for parts of southeast California, southern Nevada and Arizona.
“Temperatures well above average for the time of year — some spots as much as 10 to 20 degrees above average,” said Marc Chenard, a weather service meteorologist in College Park, Maryland. He said unseasonably hot weather was expected to spread northward and make its way into parts of the Pacific Northwest by the end of the week."
