MOST ACCURATE FORECAST: Longest stretch of triple digit days ever in Phoenix!

Posted
and last updated

PHOENIX — Phoenix is in the middle of the longest stretch of triple-digit days ever recorded!

As of Tuesday, we've had 79 days in a row at 100 degrees or hotter. The previous record was 76 triple-digit days in a row set in August of 1993.

And there is no relief in sight!

Phoenix will top out around 109 degrees through midweek before heating back up to 110 degrees starting Thursday.

Overnight lows will drop into the mid to upper 80s each day.

Valley storm chances will clear out Wednesday, Thursday and Friday as drier air moves in.

Air quality will worsen later this week, too. The Arizona Department of Environmental Quality has issued an Ozone High Pollution Watch for Thursday that could be upgraded to an advisory as we get closer.

Breathing in ozone pollution can lead to health impacts like chest pain, coughing, throat irritation, congestion and difficulty breathing. Kids, older adults and anyone with any kind of respiratory condition like asthma, bronchitis or COPD can be especially susceptible to the impacts of ozone pollution. So, limit your time outside in the afternoon when ozone pollution is peaking.

Everyone can help prevent the pollution problem from getting worse by carpooling, taking public transportation or working from home. Also, wait until after dark to fill up your gas-powered vehicles and avoid idling in long drive-thru lines.

Air quality should improve over the weekend as storm chances return. We're now tracking a slight chance of isolated storms in the Valley Saturday, Sunday and Monday.
