744 FNUS55 KPSR 101015 FWFPSR Fire Weather Planning Forecast for Southwest and South-Central Arizona and Southeast California National Weather Service Phoenix AZ 315 AM MST Fri May 10 2024 .DISCUSSION... Temperatures are expected to warm over the next several days, with chances for highs reaching 100 degrees increasing above 50%, at least for the western districts, by late this weekend. MinRHs will be in the 5-10% range across the lower deserts and in the 10-15% range across the higher terrain. Overnight recovery will be poor and in the 20- 40% range, before improved recoveries in the 30-60% range heading into early next week. Typical springtime breeziness continues through the weekend with afternoon and early evening wind gusts of 20-25 mph. These breezy conditions combined with dry fine fuels, and low RHs will likely create some elevated fire weather conditions through this weekend.
