Highlights
- Saturday's forecast high of 116 degrees would tie the all-time record for August 1 in Phoenix.
- Sunday's projected 115-degree high would break the existing daily record of 114 degrees.
- A gradual cooling trend begins Tuesday, with highs dropping to around 109 degrees by midweek.
- Rain chances remain below 20% until later next week, with isolated storms possible only in southeastern Arizona this weekend.
Phoenix is on track for a record-tying or record-breaking weekend, with Saturday's forecast high of 116 degrees set to match the all-time mark for August 1, according to Arizona's Family meteorologist Pete Mangione. An Extreme Heat Warning and First Alert Days remain in effect through Monday.
Sunday's projected high of 115 degrees would surpass the existing daily record of 114 degrees, Mangione reported. Monday holds at a forecast 114 degrees before a gradual cooling trend takes hold next week.
That cooling offers limited relief: highs are expected around 111 degrees Tuesday before settling near 109 degrees Wednesday through Friday. Morning lows may finally dip into the upper 80s by week's end.
FOX 10 Phoenix and ABC News both confirmed the record-threatening forecast, with more than 100 million people nationally under heat alerts this weekend.
Rain chances stay minimal through the weekend. A few isolated showers and thunderstorms are possible across southeastern Arizona, with a stray sprinkle possible just east of the Valley on Sunday morning. Meaningful rain chances, around 20%, don't arrive until later next week.
Residents should stay hydrated and avoid prolonged outdoor activity during peak afternoon hours. The First Alert Weather App is available on Android and iOS.
