933 FNUS55 KPSR 121039 FWFPSR Fire Weather Planning Forecast for Southwest and South-Central Arizona and Southeast California National Weather Service Phoenix AZ 339 AM MST Thu Sep 12 2024 .DISCUSSION... Hot and dry conditions will begin to cool through the end of the week, with continued cooling towards normal, and even below normal by early next week. Breezy to locally windy conditions will develop across the eastern districts for today, with afternoon wind gusts between 25-35 mph possible. Humidities will remain low through the rest of the week, with MinRHs between 5-15% across the lower elevations to around 10-20% over higher elevation areas. The combination of the low humidities and gusty winds during the afternoon hours will likely promote elevated fire weather conditions across the eastern districts for today. Conditions will gradually improve Friday into the weekend, with increasing moisture resulting in increasing RH`s and shower/storm potential going through this weekend, where wetting rain chances top out around 30-60% across southcentral Arizona by Sunday. ...Thunderstorms imply gusty winds...
