Episode Narrative Moderate snow over all of South-central and Southeast Wisconsin during the morning rush hour. Snowfall rates of 1/2 inch to 1 inch per hour combined with north winds that increased to 15 to 20 mph...with gusts between 30 and 35 mph. This combination reduced visibilities to 1/2 to 1/4 mile due to blowing and drifting snow. A coop observer in Beaver Dam in Dodge County reported 2.7 inches of snow fell in the 2.5 hours from 710 am to 940 am. Total snow accumulations of 2 to 4 inches were reported across the area with most of it falling during the morning rush hour, slowing and snarling traffic. The snow was generated by a surface low pressure which rapidly developed under the left front quadrant of a 100-knot upper jet-streak and ahead of an associated short wave trough. The low deepened as it moved from Illinois into Lower Michigan during the morning hours of January 17th...reaching eastern Ontario Canada by mid-afternoon. Strong surface to 850-mb frontogenetic forcing along with lift from the aforementioned upper level dynamics aided in the snow production.
