A freeze warning is in effect for much of Pima County, including Tucson, for Thursday and Friday nights. The first sub-32 degree temperatures will come more than five weeks after the average first freeze of the season.

A cold front Sunday will then bring rain to the city, with snow in the higher elevations. The coldest air in four years should then follow.
