An area of low pressure lifted out of the southern plains and into the Ohio Valley on January 20th (See Below for Satellite Imagery) as it interacted with an upper level disturbance that moved in from the northern plains.

Northern Illinois and northwestern Indiana experienced anywhere from 4 to over 9 inches of snowfall by the time the storm exited to the East.
