Nothing new broke in the Southwest heat file on Sunday, and the standing facts are heavy enough. Phoenix Sky Harbor reached 115 degrees Saturday afternoon, breaking the August 22 record of 113 set in 2011 by two full degrees, and the extreme heat warning now runs through Friday, August 28, with forecast highs of 110 to 115 and overnight lows stubbornly above 90.

The follow-through shows up in the national station ledger rather than in fresh headlines. Saturday's census logged ten broken heat records across Arizona alone, part of a broader Southwest haul that included Wasco, California, hitting 110 degrees, six past a 1982 mark, and La Grande, Oregon, erasing a record that had stood since 1970. [2] The warning's length is the operational point: seven straight nights above 90 deny the human body its recovery window, which is how emergency departments measure heat waves in admissions rather than headlines.
There is no updated Phoenix reading to report as of press time Sunday, and saying so plainly is the honest version of this check. Daily records are verified and posted on their own schedule; the danger does not wait for them. Outdoor workers, grid planners and anyone with an aging neighbor should treat the next five days as one continuous event rather than a series of hot afternoons. [1]
The number that matters next lands Friday, when the warning either lapses or extends again. Until then the region lives inside a forecast it already knows by heart.
