.DISCUSSION...After a very hot week, temperatures will continue
to trend down through through the weekend. Temperatures will be
several degrees above normal through next week. Near normal amount
of monsoon moisture will move in starting today. This will bring
isolated to scattered thunderstorms this afternoon, mainly south
of Tucson and up towards the White Mountains. Thunderstorm
coverage will expand tomorrow along with better wetting rain
chances. Daily chances for thunderstorms and wetting rain showers
will continue through the new week with daily variability on
coverage and intensity of thunderstorms and rain showers. Min RHs
will generally be around 14-22 percent in the lower elevations
and 20-30 percent in the mountains. There will be breezes today
for portions of the Gila River and central Pima County. These
breezes will last through most of tonight, especially on the lee
side of terrain features. Otherwise, winds will generally be less
than 15 mph with typical afternoon gusts up to 20 mph into the new
week.
