Heavy, wet snow accumulated to 3 to 6 inches over much of southern Wisconsin as surface low pressure tracked across Illinois.  Strong warm-air advection led to strong frontogenetic forcing over the region, with lift enhanced by differential positive vorticity advection associated with a 500-mb short-wave trough that crossed the region.  These features produced a steady, long-term snowfall that began in the early evening of the 23rd and lasted until the early morning hours of the 24th.  A few locations (West Bend to Mt. Mary College in Milwaukee and from Burlington to the city of Racine) received between 7 to 8 inches of accumulation, but these higher amounts were isolated and had a low impact on travel.  Therefore, this event was not documented as a winter storm.
