Red maple leaves

Red maple leaves and other hues of autumn brighten the Bear Wallow area in the Catalina Mountains.

A weak pressure system moving over southern California will reach Arizona today and tomorrow morning, causing isolated to scattered showers east of Tucson through Wednesday.

Rainfall amounts will generally be less than 0.10 of an inch in the valleys and slightly more in the mountains.

While the metro Tucson area might not see any rain, overnight temperatures will continue to drop over the next several days.
