Extreme heat returns this week

PHOENIX — Spotty storms are firing up in the high country again today. We may see flooding in a few spots, but overall the heavy rain threat is decreasing across Arizona.

Here in the Valley, our forecast is drying out for the rest of the week as extreme heat takes over.

An Extreme Heat Warning is in effect for the Valley Thursday through Monday, as temperatures climb above 110 degrees. Some spots may even top 115 by Saturday!

We won’t get much overnight relief, either. In Phoenix, lows will only fall into the 90s starting Friday morning.

As temperatures get dangerously hot, Thursday through Monday will all be ABC15 Weather Action Days as a reminder to take action to stay safe in the heat. Limit your time outside in the afternoon and make sure to drink plenty of water throughout the day.

Bring your pets inside to keep them safe from the heat too, and never leave kids or pets in the car.

We are also tracking air quality alerts here in the Valley.

An Ozone High Pollution Advisory has been issued for Thursday with an Ozone High Pollution Watch now in effect for Friday.

If you have asthma, COPD, or any other respiratory issue, limit your time outside in the afternoon hours or you may have difficulty breathing. Exposure to ozone can increase the number and severity of asthma attacks, cause or aggravate bronchitis or other lung disease, and reduce the body’s ability to fight infection.

Kids, older adults and anyone trying to exercise outside may experience health impacts from ozone pollution. Symptoms may include itchy eyes, nose and throat, wheezing, coughing, shortness of breath, chest pain, and upper respiratory issues.

We can all help prevent the pollution problem from getting worse. If you have a gas-powered vehicle, try to drive as little as possible this week. Carpooling, working from home, or re-fueling your vehicle after dark helps too.

Air quality should improve a bit as rain chances return to the Valley early next week.

2026 Sky Harbor Rainfall to-date: 0.76″ (-2.76″ from average)
