TUCSON, Ariz. (13 News) – When you stepped outside this morning, it actually felt, wait what’s the word? Oh yeah, cold! It’s been so hot, for so long, that you may have forgotten the word. With a high of only 72 in Tucson, it marked the city’s coolest day since early April! A cool day will lead to a cold night tonight & morning tomorrow, with a freeze warning in effect for valley towns out east like Willcox, Safford, & Douglas. This makes it a First Alert Action Night tonight.
