An Extreme Heat Warning and First Alert Weather Days remain in effect through Tuesday evening across the Phoenix metro, with overnight temperatures offering almost no relief from the daytime heat.
Phoenix cooled only to 97 degrees Monday morning, tying the warmest low temperature ever recorded, matching readings from July 24, 2026, and July 19, 2023. The record stands only if temperatures do not fall below 97 degrees before midnight. After reaching 116 degrees Saturday and 115 degrees Sunday, Monday's high is expected around 114 degrees, according to Arizona's Family meteorologist Pete Mangione. The NWS Phoenix office confirmed another warm overnight with a 97-degree low at Sky Harbor.
A Heat Advisory is also in effect for much of northeast Arizona until 8 p.m. Monday. Scattered showers and thunderstorms developing across Gila County and southeast Arizona could push gusty outflow winds and blowing dust into Maricopa County tonight.
Humidity will increase overnight into Tuesday, so while Tuesday's high is forecast at 112 degrees, conditions will not feel significantly different. Temperatures ease beginning Wednesday, with highs around 109 degrees, followed by 108 to 110 degrees through the weekend. The Valley carries a slight chance of showers and thunderstorms later this week.
