Phoenix is on track for a high of 114 degrees Thursday, tying the daily record, according to Arizona's Family meteorologist April Warnecke. An Extreme Heat Warning remains in effect through Saturday night, with Friday and Saturday also designated First Alert Weather Days for heat.
Relief is building. A major weather pattern change is taking shape as high pressure shifts, an area of low pressure moves into the Northwest, and tropical moisture may push into Arizona. Storm chances reach near 40 percent for Saturday evening and night, then climb to near 50 percent by Sunday, when strong storms and heavy rain are both possible threats.
Temperatures will track downward alongside the storm activity. Warnecke forecasts a high of 105 by Sunday and 101 by early next week, with enough rainfall potentially pushing a day into the 90s.
The NWS Phoenix office and corroborating coverage from Hoodline confirm the Extreme Heat Warning and record-level temperatures across the Valley. Sunday's storm window is the one to watch for Scottsdale and Paradise Valley residents with outdoor events or construction timelines on the calendar.
