We’re not used to this!  So far it has been a mild winter with January’s  average temperature running about 9° above normal.  No wonder the sub-zero temperatures we woke up to this morning felt even colder.  The morning low in Green Bay was -2° which is the first sub-zero of  this season.  Usually we see our first sub-zero temperature on December 20th.  This cold snap will continue for the next few days.  A quick-moving storm system moves to the north of the state tonight and will bring snow showers and then leave even colder air in its wake.  Expect a high only near 6° tomorrow and strong west winds of 15 to 25 mph which keeps the wind chills below zero all day.  After a morning low on Friday of -5° we’ll see accumlating snow on Friday afternoon and evening  with 1 to 3 inches possible for us.  Find the long underwear and have a great day!
