A couple of men brave the snow to walk around in Summherhaven in the Santa Catalina Mountains on Tuesday, April 9, 2013, in Tucson, Ariz. The National Weather Service in Tucson is looking for volunteer observers to record and report snowfall on Mount Lemmon this winter.

Get ready for temperatures to plummet, as widespread cold conditions are expected for the end of the work week.

A Hard Freeze Watch for low temperatures below 28 degrees and a Freeze Watch for lows around 32 degrees are in effect late Thursday night into Friday morning, which would bring the first freeze of the season to the metro area.
