Tucson, Arizona – Afternoon heat and summer storms return to southern Arizona today as Tucson braces for a sweltering 106°F high and a chance of thunderstorms by late morning.
According to the National Weather Service, a 20 percent chance of showers and storms will develop after 11 a.m. Sunday, July 6.
