Phoenix hit 115 degrees Saturday, breaking the previous record of 113 degrees set in 2011, as an Extreme Heat Warning and First Alert days were extended through Aug. 22, according to Arizona's Family meteorologist Pete Mangione.

An ozone-driven air quality alert remains in effect through Sunday. Isolated showers and thunderstorms will persist across southern and eastern Arizona Saturday evening, bringing a slight chance of gusty outflow winds into the Valley overnight.

Sunday will offer marginal relief, with a high near 111 degrees. Late Sunday night into early Monday carries a 20% chance of gusty winds, blowing dust, and thunderstorms. Highs ease to around 109 on Monday before climbing back to between 112 and 115 degrees Tuesday through Saturday, threatening additional record-breaking temperatures.

High country scattered showers and storms will continue through Monday before drying out midweek.

The record was independently confirmed by KTAR and 12News. The National Weather Service Phoenix forecast office can be monitored at weather.gov/psr.
