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.
