The rapid snow melt has become too much to handle for many southern Wisconsin rivers and streams, with flooding reported on dozens of highways, people being evacuated in Fond du Lac and at least one record breaking water level in Columbia County.
In Fond du Lac, the Associated Press reported workers have helped as many as 300 people evacuate from their homes because of ice-jam flooding along the Fond du Lac River in eastern Wisconsin.
Fond du Lac Fire Division Chief Troy Haase said firefighters have been to 15 homes and three separate apartment buildings to help people evacuate Thursday as water swamped local roads and basements.
Spring Creek in Lodi reached 8.6 feet Thursday morning, breaking the historic crest level of 8.4 feet set twice, in June 2008 and June 2014.
That is just one of multiple flooding scenarios being played out all over southern Wisconsin, as temperatures climb to 60 and the snow cover has essentially been eliminated.
The flooding could be exacerbated Thursday afternoon as a cold front moves through the area, with scattered to numerous thunderstorms developing.
"There is a marginal risk these storms could become severe," the National Weather Service said. "Damaging winds is the primary threat."
A flood warning has been issued for Black Earth Creek in Mazomanie, with the stream a foot above flood stage at 11.0 feet. Flood forecasts aren't issued for that location, but the warning will stay in place until the stream falls below flood stage.

Frozen ground conditions still abound throughout southern Wisconsin, so the melted snow has nowhere else to go but into low-lying areas, rivers, fields, etc.
The state highway travel map has about two dozen road closings pinpointed as of 1 p.m. Thursday, but that's mainly for major highways, so if you are traveling to or from a certain area, check with local authorities to see if your route is good to go.
In the counties covered by the Weather Service Milwaukee Region, 32 out of 130 river gauges were at flood stage.
Flood watches and warnings are in effect until Friday morning in most areas, but rivers will be monitored throughout the region during the weekend to see if warnings need to be extended, the Weather Service said.
Rain is expected to continue into early Friday morning, but the cold front should drop temperatures to the low 30s, meaning we could see snow mixed with rain before it all ends Friday afternoon.
The rest of the weekend and the first part of next week looks good, albeit not near the 60-degree weather we are seeing Thursday.

- Thursday afternoon: A 60 percent chance of showers and thunderstorms, winds gusting up to 30 mph. Rainfall of less than a tenth of an inch is forecast, with higher amounts in storms.
