MOST ACCURATE FORECAST: Sizzling heat and an air quality alert this weekend

Posted
and last updated

PHOENIX — It's going to be the hottest weekend of the year so far!

Phoenix will be topping out near 105 degrees on Saturday and Sunday with early morning lows in the 70s.

We're also tracking more pollution problems. Another Ozone High Pollution Advisory is in effect on Saturday across the Valley and an Ozone High Pollution Watch has been issued for Tuesday. (That could be upgraded to an advisory as we get closer.)

If you have asthma, COPD, or any other respiratory issue, limit your time outside in the afternoon hours on high pollution days 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 this ozone pollution, too. 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 vehicle, try to drive as little as possible this week. Carpooling, working from home, or re-fueling your vehicle in the evening helps, too.

We are now headed into prime ozone pollution season in the Valley during these long, sunny days, so this will likely continue to be an issue throughout much of June.

It's prime heat season in the desert, too. Here in the Valley, temperatures will stay in the triple digits for the foreseeable future with early morning lows in the upper 60 to mid 70s.

Phoenix could even hit 110 degrees for the first time this year late next week!

On average, Phoenix tends to see its first 110-degree day around June 11th. The earliest on record was May 8, 1989.
