Southern Wisconsin received much less snowfall on Saturday than anticipated. The main reason was that the spring storm that was expected to pass to the south of Wisconsin took a farther south track. On Thursday, the storm was expected to move across Iowa and northern Illinois. Instead, it took a track across northern Missouri and southern Illinois. This resulted in less snowfall as well as a delay in the snow onset time across southern Wisconsin, due to lingering drier air in place.

South track

Snowfall on Saturday was mainly confined to the southern three tiers of Wisconsin counties. Snowfall was generally in the 3 to 6 inch range in the counties near the Illinois border, with the Monroe, New Glarus and Kenosha areas reporting around 5.5 to 6.0 inches. Lower amounts were found to the north, with northern parts of the area not seeing any snow.

Madison received 1.2 inches which set a new record for April 27th. Milwaukee received 1.7 inches, which also set a new record for the date.

Despite wet weather returning at times through Wednesday, no additional snow is expected.
