Southern Wisconsin recorded another couple inches of snow in most areas as a warm front passed through the region under an upper level disturbance. The combination of the warm front and disturbance provided the ingredients for snow on Monday with freezing drizzle moving over the area early Tuesday morning. The snow began to fall in southwestern Wisconsin mid day Monday and began a progression to the east and north through the rest of the day. The snow eventually moved into the counties along Lake Michigan in the evening and lasted into early Tuesday morning. Patchy freezing drizzle mixed in with the light snow early Tuesday, with light accumulations of around a hundredth of an inch being reported in multiple areas.
