Minor Accumulating Snow Possible Friday Night

Temperatures heading into the weekend will be cold enough to support minor accumulating snow Friday night and early Saturday morning.  We have had snow late this Fall season, but most of what fell accumulated on grassy surfaces and was gone by that afternoon.  What is expected to come in Friday night will most likely stick on sidewalks and roadways, and could cause some slick spots early Saturday morning.


A fast moving clipper system, currently near Alaska, will quickly move through Canada and into the Upper Midwest by Friday morning.  This will cause an area of low pressure to develop over Minnesota and slide southward into Wisconsin and over Lake Michigan by Saturday morning.


There isn't a great deal of moisture with this system, but just enough to possibly cause half an inch, up to two inches, of snow to accumulate.  Higher snow totals will most likely be near Chicago and northwest Indiana, closer to the center of low pressure system, with lighter totals found to the west.


Following the snow will be another shot of cold air Saturday.  Temperatures on Saturday will only warm into the 20's.  A second system worth monitoring does move in on Monday, and then again Tuesday night into Wednesday.
