Extreme heat & storm chances

PHOENIX — One more day of extreme heat is headed our way before a cool-down arrives this weekend.

Extreme Heat Warnings are in effect across much of central, southern and western Arizona through Saturday evening as temperatures continue to soar near or above 110 degrees each day.

So, we remain in ABC15 Weather Action Mode this week as a reminder to take action to protect yourself, your family and your pets from the dangerous heat.

Stay hydrated, limit your time outside between 10 a.m. and 6 p.m., and bring your pets inside too. If you have to be outside, wear lightweight, light-colored clothing and take frequent breaks in the shade or air conditioning.

We are also tracking air quality alerts in the Valley.

An Ozone High Pollution Advisory is in effect on Friday, and a High Pollution Advisory has also been issued for Friday and Saturday due to lingering dust in the air and chances for more to blow in.

To prevent air quality from getting even worse, the Maricopa County Air Quality Department has issued a “No Burn Day“. That means burning wood in fireplaces, stoves, and outdoor fire pits is prohibited overnight.

Ozone pollution can trigger asthma attacks, aggravate bronchitis and other lung diseases, and weaken the body’s ability to fight infection. If you have asthma, COPD or any respiratory condition, stay inside during the afternoon when pollution peaks.

Kids, older adults and anyone exercising outside may feel the effects, too. Watch for itchy eyes, nose and throat, along with wheezing, coughing, shortness of breath and chest pain.

Monsoon storms will fire up in the heat of the day across the high country and in areas just east of the Valley. There is a slight chance of a few isolated storms making it into the Phoenix metro area late tonight.

Storm chances will increase over the weekend with the best shot for rain in the Valley on Sunday and Monday. These storms will bringing strong winds, blowing dusts, lightning, isolated pockets of heavy rain and possible localized flooding.

Temperatures will also drop each day down to the low 100s by Monday and overnights in the low 80s too!

2026 Sky Harbor Rainfall to-date: 1.57″ (-3.12″ from average)

2026 Monsoon Rainfall to-date: 1.25″ (-0.52″ from average)
