MOST ACCURATE FORECAST: First triple-digits of the year in Phoenix!

Posted
and last updated

PHOENIX — Phoenix hit the triple digits for the first time this year!

This ties the record for the fourth earliest 100-degree of the year.

It also ties the daily heat record of 100 degrees set in 2018.

On average, Phoenix sees its first 100-degree day in early May, so this early-season heat comes with a minor to moderate risk of heat exhaustion or heat stroke, especially for children, seniors and outdoor workers.

Stay hydrated, limit your time outside in the afternoon, and never leave kids or pets in your car for any amount of time.

The daily heat records of 99 degrees on Friday and Saturday could be broken too, as temperatures continue in the low 100s.

High pressure is bringing the heat, but it's also leading to stagnant air, which allows pollution to build up.

Ozone High Pollution Advisories are in effect through Friday in the Valley.

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 this ozone pollution, too. Symptoms may include itchy eyes, nose and throat, wheezing, coughing, shortness of breath, chest pain and upper respiratory issues.

To prevent the pollution problem from getting worse, try to carpool, take public transportation or work from home. Even refueling your vehicle after dark will help.

Air quality will improve and temperatures will drop over the weekend as winds pick up.

Those stronger winds could increase fire danger across our state, especially across southeastern Arizona where peak gusts could hit 35 to 40 mph.

Here in the Valley, expect breezes Saturday and Sunday with gusts near 25 to 30 mph.

Temperatures will drop back into the mid 90s heading into next week.
