999 FNUS55 KPSR 060919 FWFPSR Fire Weather Planning Forecast for Southwest and South-Central Arizona and Southeast California National Weather Service Phoenix AZ 219 AM MST Sun Oct 6 2024 .DISCUSSION... Extreme heat will continue for many areas through Tuesday, with lower desert highs ranging between 106-112 each afternoon. Very dry conditions are expected today through Monday afternoon, with RH values under 25% in most areas for the next 36-48 hrs, including afternoon MinRH values in the single digits for nearly all areas. An increase in winds above the surface during the overnight hours, including this morning and again tonight/Monday morning, may lead to very localized elevated fire weather conditions in South-Central AZ. Easterly winds during the overnight hours on and near ridgetops will be capable of reaching 25-35 mph at times, mostly in the mountains east of Phoenix. Otherwise, winds will remain light in sheltered valley and lower desert locations and follow typical diurnal upslope and downslope directions. Afternoon gusts occasionally up to 15-25 mph can be expected with mixing. Note...Additional Fire Weather Forecast information can be found in the Area Forecast Discussion. See product PHXAFDPSR.
