TUCSON, Ariz. (KOLD News 13) - Excessive Heat Warning active for central and western Pima county Tuesday and Wednesday, with Tucson and parts of Graham and Greenlee county added to it on Wednesday. Drier air sifts in today leading to less shower and storm coverage for the start of the work week. Isolated storms possible near the International Border. By Thursday high pressure will shift opening southern Arizona to more storm activity. This leads to a return of storms heading into the weekend with temperatures falling back into the 90s.
