quote [ The heatwave in the Southwest is so bad that American Airlines had to cancel 50 flights

American Airlines said it cancelled 50 flights out of Phoenix Sky Harbor aboard Bombardier CRJ aircraft on Tuesday because the planes can’t operate above 118 degrees.

Phoenix, Tucson and Las Vegas are forecast to be within striking distance of all-time records. All eyes will be on Phoenix, which is ground zero for the heat wave. Temperatures are forecast to climb to 120 degrees on Tuesday, just 2 degrees shy of its all-time record ]
