766 FNUS55 KPSR 252206 FWFPSR Fire Weather Planning Forecast for Southwest and South-Central Arizona and Southeast California National Weather Service Phoenix AZ 306 PM MST Sat Jul 25 2026 .DISCUSSION... Daily chances for afternoon/evening showers and thunderstorms will exist over portions of the eastern districts into early this upcoming work week, with better chances focused over the higher terrain. Strong, gusty winds and long-lived outflows will be the main concern this evening. Very hot, above normal temperatures will continue, but several degrees cooler Sunday and Monday compared to Saturday thanks to increased cloud cover and high pressure weakening and shifting northward. Afternoon minimum humidities between 15-20% in the western districts will follow overnight recoveries around 25-55%, and in the eastern districts, afternoon humidities between 20-25% will be common following fair to good overnight recoveries between 35-60%. Outside of thunderstorms, winds will follow typical diurnal tendencies with afternoon/early evening upslope gusts around 15-25 mph. ...Thunderstorms imply gusty winds...
