If you thought this week was cold, just wait. The most frigid air of the season will be settling in to welcome the new year.
But first, we will have a little snow to contend with. Let's start there.
Light snow will develop from west to east Saturday. The snow will begin between 7 a.m. to 9 a.m. Saturday and continue through 3 p.m. to 5 p.m.
While the snow will not be heavy, it will fall on extremely cold ground allowing it to accumulate immediately. Any untreated roadways tomorrow will be slippery and dangerous due to the light snow compacting and turning into ice. Any neighborhood that has hills could be an ice skating rink.
