275 FNUS55 KPSR 052120 FWFPSR Fire Weather Planning Forecast for Southwest and South-Central Arizona and Southeast California National Weather Service Phoenix AZ 220 PM MST Sat Jul 5 2025 .DISCUSSION... Near-normal temperatures will persist through today, with above- normal readings returning by Sunday and persisting into early next week. Relatively high moisture across the eastern districts will translate to MinRHs between 15-25%, but for the western districts, values will range closer to 10-15% this afternoon. Those lower values become more common Sunday across the region as drier air spreads further east. Overnight recoveries will only offer marginal relief, as MaxRHs hover between 20-45% over the next few days. Winds will follow familiar diurnal trends, with typical afternoon breeziness. Rain chances will be limited through the weekend, with the best chances (10-30%) along the Maricopa, Pima County border this afternoon. ...Thunderstorms imply gusty winds...
