What happened

The episode as NWS MKX wrote it up.

Several periods of dense fog affected south-central and southeast Wisconsin for 2 to 3 days thanks to recent rains and snowmelt saturating the lower atmosphere. At times visibilities were reduced to 1/16 of a mile or less, and in some cases down to 50 to 100 feet. Some vehicle drivers indicated that driving through the fog was downright scary or dangerous. A good number of airplane flights were delayed, and some were canceled, at the larger airports. One spotter 5 miles southeast of downtown Madison (Dane Co.) noted that the visibility was the worst he has seen in many years and he could barely see 2 or 3 houses away. Newspaper reports indicated that several vehicle accidents occurred.
