Tucson’s coldest day ever

TUCSON - Colder weather is in the forecast and by Friday morning, some light snow could be falling across some of the lowlands of southern Arizona, mainly above 4,000 feet.

High temperatures on Friday will struggle to get out of the 50s.

But Tuesday's date marks a climatological milestone for the city of Tucson and it happened 107 years ago Tuesday.

So while we enter this upcoming 'cool' stretch, think about how cold Tucson has actually gotten from a historical perspective.
