076 FNUS55 KPSR 272136 FWFPSR Fire Weather Planning Forecast for Southwest and South-Central Arizona and Southeast California National Weather Service Phoenix AZ 236 PM MST Mon Jul 27 2026 .DISCUSSION... Typical monsoon conditions are expected through the next few days, with thunderstorm activity mainly favoring the high terrain of northern AZ and southeastern AZ and low chances (10%) in the lower deserts of south-central AZ. Above normal temperatures will contribute to seasonally dry afternoon conditions each day through the first half of the week. Minimum RH values of 15-30% will be common, with fair overnight recoveries most nights - maximum RH values mostly in the 35-50% across lower deserts to 45-65% across southern Gila County. Outside of thunderstorm outflows, wind speeds should be fairly light through the period with only local afternoon gusts 20-25 mph. ...Thunderstorms imply gusty winds...
