225 FNUS55 KPSR 290826 FWFPSR Fire Weather Planning Forecast for Southwest and South-Central Arizona and Southeast California National Weather Service Phoenix AZ 126 AM MST Tue Jul 29 2025 .DISCUSSION... Limited monsoon moisture will provide for daily chances of scattered showers and isolated thunderstorms over the eastern Arizona high terrain, but chances for wetting rains will mostly be 10% or less. By Thursday, the limited chances may extend into the south-central Arizona lower deserts. The lack of good moisture should result in at least minor risk of dry lightning. Afternoon MinRHs for the lower deserts will remain between 5-15% today and Wednesday, with 15-20% in southern Gila County. Outside of the influence of thunderstorms, winds will generally follow diurnal tendencies with typical afternoon upslope gustiness. Temperatures will mostly run 3-6 degrees above normal through the rest of the week. ...Thunderstorms imply gusty winds...
