MOST ACCURATE FORECAST: Air quality alert in the Valley, thunderstorms up north

Posted
and last updated

PHOENIX — The triple digits are back in the Valley!

Today marked our fourth day this year in the 100s so far and we'll see many more in the days ahead.

Air quality is getting worse too as skies stay clear and winds lighten up. So, the Arizona Department of Environmental Quality has issued Ozone High Pollution Advisories today and tomorrow for the Phoenix metro area.

If you have asthma, COPD or any other respiratory condition, you may want to limit your time outside in the afternoon hours when ozone pollution is at its peak or you may experience chest pain, coughing, throat irritation and congestion. Kids, older adults and anyone exercising outdoors may experience symptoms from ozone pollution, too.

We can all help to reduce pollution levels by limiting driving of gas-powered vehicles, carpooling, using public transportation or working from home. Also, wait until after dark to refuel vehicles and avoid idling in long drive-thru lines.

As a weak storm system moves through, we'll also see chances for showers and thunderstorms across parts of the high country throughout the week.

There won't be a lot of rain with these storms, so we'll have to watch out for lightning-sparked wildfires and gusty winds.

Temperatures will drop slightly as this storm moves in, but mid to upper 90s is as low as we'll go in the Valley.

Then, the triple digits will return Friday and stick around through the weekend as another ridge of high pressure builds in.
