NWS Forecast Office Tucson, AZ

A backdoor frontal boundary nudging into the area from the east will result in a breezy to locally windy day across Southeast Arizona on Sunday. East to southeast winds 15 to 25 mph with gusts to 35-40 mph will be possible east of Tucson. These winds may result in localized blowing dust, especially across the Upper Gila River and San Simon valleys near the Arizona/New Mexico state line. The good news is that this frontal boundary will bring afternoon temperatures east of Tucson down to near normal readings for this time of year, with temperatures between 5-10 degrees above normal anticipated from Tucson west.
