MOST ACCURATE FORECAST: Monsoon storms possible overnight before extreme heat returns

Posted
and last updated

PHOENIX — It has been a brutal July of record-setting heat, but on this last day of the month we finally dropped below 110 degrees. (Our official high in Phoenix was 108 degrees.)

Phoenix reached 110 degrees or higher for an all-time record of 31 days in a row. (Previously, the record was 18 days in a row set in 1974.)

Extreme heat will return by the end of the week, but we should stay below 110 degrees again on Tuesday.

Monsoon storms have been bringing heavy rain, flooding, powerful winds, hail and lots of lightning to parts of Arizona.

Now, it's the Valley's chance to see storms in the overnight hours and we could really use some rain.

Phoenix is in the middle of the 4th longest dry streak on record. It has been 130 days since we've had measurable rain at Sky Harbor.

There is a slight chance of a few isolated storms on Tuesday and Wednesday, too. Then, we'll be drying out and heating up once again.

Phoenix will likely top110 degrees again on Wednesday and highs could approach the 115 mark again by Friday. That will put us back in record territory heading into the weekend.

Heat is the number one weather-related killer. So, limit your time outside during the hottest part of the day and stay hydrated. Keep an eye on kids and the elderly as they can be the most affected by this heat. Bring your pets indoors, too.

Air quality is also going to be an issue this week with ozone pollution reaching unhealthy levels for kids, older adults and anyone with any kind of respiratory condition.

An Ozone High Pollution Advisory is in effect for through Tuesday and an Ozone High Pollution Watch in effect for Wednesday. If you have asthma or COPD, plan on limiting your time outside or you may have difficulty breathing.
