MOST ACCURATE FORECAST: Sizzling heat, air quality alerts and chances for monsoon storms

PHOENIX — It's a hot start to the week in the Valley!

Temperatures will flirt with 110 degrees again in Phoenix on Tuesday, but thankfully overnight lows will drop into the 80s.

Phoenix has already had 53 days so far this year at 110 degrees or hotter. The all-time record is 55 days, set just last year. We'll be inching toward that record over the next seven days as temperatures remain hot heading into September.

There is also no end in sight to this record-setting stretch of triple digits days. As of Monday, we've had 92 triple-digit days in a row. The previous record was 76 consecutive triple-digit days set in August of 1993.

Most of the monsoon action will be in southeastern Arizona again on Tuesday, but slight chances for isolated showers and thunderstorms will be in play in the Valley with an increased chance overnight into Wednesday morning.

That should help drop temperatures a few degrees with Valley highs near 105 on Wednesday.

Then, we'll be drying out and heating back up through Labor Day weekend with more 110s possible in Phoenix.

Air quality is also a concern as ozone pollution builds up this week, causing potential health impacts for some of us.

An Ozone High Pollution Advisory is in effect on Tuesday and Ozone High Pollution Watches are in effect Wednesday, Thursday and Friday.

Ozone pollution could reach unhealthy levels for kids, older adult and anyone with any kind of respiratory condition like asthma, bronchitis, or COPD.

Limit your time outside, especially during the afternoon hours when ozone pollution is at is worst, or you may experience chest pain, coughing, throat irritation, congestion or even difficulty breathing.
