MOST ACCURATE FORECAST: Storm chances backing off this 4th of July weekend

Posted at 5:57 AM, Jun 30, 2022

PHOENIX — Monsoon 2022 has been bringing gusty winds, blowing dust, lightning and pockets of heavy rain across Arizona.

Chances for showers and thunderstorms will continue through the end of the week with the majority of the action in northern and eastern Arizona.

Here in the Valley, there's just a slight chance of spotty storms overnight and Friday.

Ozone pollution could reach unhealthy levels, too.

An Ozone High Pollution Advisory is now in effect through Friday. Limit your time outside if you have COPD, asthma or any other respiratory condition, or you could have difficulty breathing.

Humidity will stay high and temperatures will stay hot.

Valley highs will top out between 104 and 106 degrees over the next several days.

Morning lows will only drop into the mid to upper 80s, so we are not expecting much relief overnight.

While we may see a few isolated storms along the Mogollon Rim or in southeastern Arizona through the weekend, our Valley forecast is looking dry.

Expect to stay storm-free here in Phoenix through the 4th of July and into next week.
