511 FNUS55 KTWC 042119 FWFTWC Fire Weather Planning Forecast for Southeast Arizona National Weather Service Tucson AZ 219 PM MST Fri Jul 4 2025 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 20-FOOT WIND FORECAST OF `LIGHT WINDS` INDICATES MAINLY TERRAIN DRIVEN WINDS +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ .DISCUSSION...Slightly below normal temperatures this afternoon, then warming back this weekend into next week with the potential for very hot temperatures to return the middle of next week. Expect isolated to scattered showers and thunderstorms this afternoon into this evening mainly south and southeast of Tucson. A decrease in thunderstorm activity is expected this weekend as the area transitions into a low grade monsoon pattern. An eventual uptick in monsoon activity is possible the middle of next week but will be dependent on how quick the high pressure aloft shifts north. Winds generally light and under 15 mph with the exception of gusty and erratic winds up to 35-45 mph near any thunderstorms.
