FNUS55 KPSR 160910 FWFPSR Fire Weather Planning Forecast for Southwest and South-Central Arizona and Southeast California National Weather Service Phoenix AZ 210 AM MST Fri Oct 16 2026 .DISCUSSION... Drier air will persist over the region over the next couple of days with mostly clear skies and seasonally low humidities. MinRHs will be between 15-30% across the region through Saturday. Winds will turn easterly and become stronger through the early morning hours today and last through Saturday across southern AZ. Winds will be strongest over mountain tops during the overnight and early morning hours today and again Saturday, with gusts up to 45-55 mph. Strong gusty winds will spread more to the lower deserts during the daylight hours and be strongest in the morning through early afternoon today, with gusts up to 40-45 mph. These strong easterlies and 20-25% RHs may still create locally elevated fire weather conditions midday through the afternoon today, but fuels are not the most receptive after recent rains. The easterly breezes will not be nearly as strong during the day Saturday and will trend down further into Sunday. Light showers are possible this weekend, but the chance for wetting rain is low (<10%). ...Thunderstorms imply gusty winds...
