PHOENIX — Dangerous heat is back in the forecast with high pressure moving west over Arizona, much of our monsoon moisture will get cut off and the heat will be cranking up.
Excessive Heat Warnings are in place now through Tuesday night for northern, western, central and southern Arizona.
We are now in ABC15 Weather Action mode as a reminder to take action to keep you, your family and your pets safe in the extreme heat. Limit your time outside, stay hydrated and bring your pets inside, too.
Phoenix temperatures could tie or even break daily records Monday and Tuesday as temperatures hit 113 to 115 degrees.
Monday's record high is 113 degrees, set back in 2009. The forecast is 115.
Tuesday's record high is also 113 degrees, set back in 2009. The forecast is 115.
Phoenix has already had 49 days this summer 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 as the high heat continues.
Phoenix has also had 20 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 may add to this tally too before the summer ends.
We could also see more overnight lows in the 90s. We're now up to 31 days with lows in the 90s, breaking the previous record of 28 days set in 2020.
As temperatures climb and skies stay mostly sunny, our air quality will get worse, too.
An Ozone High Pollution Advisory is in effect again tomorrow. Ozone pollution could reach unhealthy levels those days making it difficult to breathe if you have asthma or COPD. So, you may want to limit your time outside if you have any kind of respiratory condition.
Showers and thunderstorms will continue to impact some parts of Arizona. The Valley will look to stay dry until the end of the week, when storm chances return and our temperatures look to drop below 110.
