What happened

The episode as NWS MKX wrote it up.

South winds ahead of a low pressure moving through the Madision (Dane Co.) area pulled mild air into southern Wisconsin allowing Milwaukee to establish a new daily record maximum temperature of 56 at 1316CST. The old record was 54 set back in 1897. Above normal temperatures from the beginning of winter had an effect on the ice-over of Lake Mendota and Lake Monona in Madison. On January 14th both lakes finally froze over, making it the second latest ice-over (Jan 30, 1932 is the latest). Average ice-over dates are December 20th for Lake Mendota and Dec 15th for Lake Monona). Both lakes have tended toward earlier openings over recent years, such as in 1998 when Mendota lost its ice cover on February 27th after freezing over on Jan 11th. That was the shortest ice-cover period on record.
