A slow moving low pressure system tracked across Iowa into central Illinois. A warm front extending east from the low helped define a sharp contrast in temperatures across the region. Warm air flowing north ahead of the low was lifted across the frontal boundary which helped to squeeze the moisture out of the air. This, in part, helped produce a hefty snowfall across parts of the state.

The hardest hit areas were in west central Wisconsin where 15 to 20 inches of snow fell between the morning of Thursday, March 17 through Sunday morning, March 20. Snowfall amounts diminished sharply to the south and north due to the presence of dry air and it's ability to prevent the snow from advancing into these regions.
