EXTREME HEAT WATCH: The National Weather Service in Phoenix has issued an Extreme Heat Watch covering Scottsdale, Paradise Valley, and eight additional metro zones, running from Thursday morning through Monday evening, July 27, at 8 p.m.
Afternoon temperatures of 108 to 115 degrees are possible across the affected areas, which include Buckeye/Avondale, Central Phoenix, Deer Valley, East Valley, North Phoenix/Glendale, Northwest Valley, South Mountain/Ahwatukee, and Southeast Valley/Queen Creek.
