Tucson - The coldest air-mass in nearly 10 months is moving into the region. Freeze Warnings are posted for the City of Tucson as temperatures are expected to plummet to 32 degrees, and even lower by early Friday morning.
The cold air will stick around for much of the weekend with highs in the 50s and and lows dipping into the 30s.
A reinforcing shot of cold air arrives late on Saturday and into Sunday for another chance of valley rain and mountain snow showers.
