The heat will stick around throughout the holiday weekend in Phoenix, with highs in the triple digits.
PHOENIX - Happy 4th of July! It was a cloudy start to the holiday weekend with clearing skies and hotter days ahead.
What to Expect :
Due to the increasing clouds, Phoenix hit a high of 101 degrees, which is 7 degrees below average. Below-average temperatures will come to an end as a large ridge of high pressure from the east will amplify.
Extreme heat watches are in place for areas in Maricopa, Pinal, Pima, Yuma and La Paz counties to name a few. Watches begin Tuesday and extend through Thursday for temperatures ranging from 107 to 117 degrees. Clouds will clear by Sunday afternoon with sunshine returning for the rest of the holiday weekend.
Looking Ahead to Next Week:
Make sure to drink plenty of water and reduce outdoor activities as temperatures get dangerously hot. Next week’s moisture chances look to favor eastern Arizona with a potential for moisture in the Valley later on.
