MOST ACCURATE FORECAST: Sizzling heat! Valley air quality alerts, too

Posted
and last updated

PHOENIX — It's a hot week in the Valley of the Sun!

Temperatures will be topping out around 106 degrees Wednesday and Thursday, which is normal for this time of year.

Sunny skies and light winds are leading to air quality issues, too.

Another Ozone High Pollution Advisory is in effect Wednesday in the Phoenix metro area. That means air quality will be unhealthy to breathe for kids, older adults and anyone with any respiratory issues like asthma or COPD.

Breezes will pick up on Thursday, mixing our air and limiting the amount of pollution build-up.

But, with lighter winds again Friday and Saturday, Ozone High Pollution Watches are in effect that will likely be upgraded to Advisories as we get closer.

Valley temperatures will drop slightly on Friday as a disturbance passes to our northwest, but it won't be enough to get us out of the triple digits.

With high pressure intensifying to our southeast over the weekend, we're now tracking the hottest temperatures of the year so far!

Phoenix could see its first 110-degree day by Sunday or Monday. On average this happens around June 11th, so this is a little later than usual.

While Monsoon 2023 is officially here, our forecast still looks sunny and dry with no rain in sight over the next week.
