MOST ACCURATE FORECAST: First 100s of the year possible Friday and Saturday

Posted at 4:56 AM, May 04, 2022

PHOENIX — Temperatures are heating up as high pressure builds in!

Phoenix could hit the triple digits for the first time this year Friday or Saturday.

On average, our first 100-degree day of the year occurs in early May, so this is right on cue. This may also be the latest first 100-degree day since 2010!

Winds will stay light across the Valley on Friday leading to high ozone pollution once again.

The Arizona Department of Environmental Quality has issued an Ozone High Pollution Advisory for Friday. So, limit your time outside if you have a respiratory condition, like asthma or COPD, or you may have difficulty breathing.

Winds will pick up over the weekend leading to better air quality across the Valley.

As the next storm system approaches, it will get windy all across Arizona on Sunday for Mother's Day.

Conditions are looking dry, so fire danger will be increasing too. Fire Weather Watches are now in effect Saturday and Sunday across northern Arizona.

That storm system will keep breezy to windy conditions in our forecast through the middle of next week as temperatures drop.

Valley highs will fall into the mid 90s on Sunday and low 90s early next week.
