Light Snow Possible for the Start of the Weekend

Accumulating snow is possible over northern Illinois and southern Wisconsin late Friday night and Saturday afternoon.  A disturbance in the jet stream will move in from the west during the afternoon Friday as low pressure develops over the southern Plains.  Moisture will be pulled northward into the Mid-Mississippi River Valley through Friday night, despite high pressure centered over the northern Great Lakes.

Snow will move in from the southwest late Friday night, around Midnight, and continue through the afternoon Saturday.  As of Wednesday evening, it looks like the higher accumulations will occur over central and southern Illinois, but a couple inches of snow will be possible into northern Illinois.  While this won't be a big snow system, it may be one where you have to pull out the shovel Saturday. 

December was a very dry month with respect to snow with less than an inch falling for the entire month!  So if accumulating does occur Saturday, it'll most likely be the biggest snowfall since the heavy snow that came down Thanksgiving weekend.  Stay tuned!
