PHOENIX — Record-breaking heat is back in the Valley!
We set two new daily temperature records again on Tuesday, just like we did Monday.
Phoenix only cooled to 93 degrees Tuesday morning breaking the record warm low of 90 degrees set in 1981.
Then, Phoenix hit 116 degrees Tuesday afternoon breaking the old record of 113 degrees set in 2009.
Wednesday could bring even more record heat before temperatures really start to drop.
Phoenix is only expected to hit 92 degrees early Wednesday morning, which would top the current record of 91 degrees set in 2007.
Wednesday's forecast high is 113 degrees which could tie the record set in 2011.
Excessive Heat Warnings for the Phoenix metro and all of south-central and southwestern Arizona have now been extended until 8 p.m. Wednesday.
So, we remain in ABC15 Weather Action mode as a reminder to take action to keep yourself, your family and your pets safe in this extreme heat. Limit your time outside, stay hydrated and bring your pets inside, too.
Phoenix has already had 51 days this summer with highs at 110 degrees or hotter. That's the second most ever recorded. The record is 53 days set in 2020 and we will be inching closer to that record over the next several days.
Phoenix has also had 22 days so far at 115 degrees or hotter, the most ever recorded in a single year. Previously, the record was 14 days set in 2020. We will add to this tally too.
We could also see more overnight lows in the 90s. We're now up to 33 days with lows in the 90s. The old record was 28 days set in 2020.
As temperatures climb and skies stay mostly sunny, our air quality has been getting worse too.
An Ozone High Pollution Advisory is in effect through Wednesday. Ozone pollution could reach unhealthy levels making it difficult to breathe, especially if you have asthma or COPD. So, you may want to limit your time outside if you have any kind of respiratory condition.
While storm chances across Arizona look low today, we'll see more showers and thunderstorms across the higher terrain of northern and eastern Arizona. We could see an isolated storm approach the Valley late tonight or late tomorrow night, but most of the Phoenix metro area will stay dry.
As high pressure shifts farther east on Thursday and Friday, more monsoon moisture will return bringing storm chances back to the Valley.
As storm chances ramp up, temperatures will drop. Valley highs will fall back into the upper 90s to low 100s starting Friday and continuing through Labor Day weekend.
