Grass isn't always greener: Flooding may persist into weekend for southern Wisconsin

Mild temperatures and rain showers Tuesday and Wednesday melted much of the snow across southern Wisconsin.

As a result, for the first time in about two months, the grass is starting to re-emerge in some spots.

However, with frost depths of 1 to 2 feet locally, any grass that has lost the snow isn’t able to absorb much water. Instead, the rain and melted snow is heading straight to area rivers, streams and creeks.

Flooding is expected along portions of the Baraboo, Fox, Sugar and Pecatonica rivers into this weekend. In Sauk County, there have already been reports of water coming into homes.

There have also been numerous reports of road closures due to high water across the area Wednesday. Localized street flooding will continue into Thursday and early Friday. Remember, if you encounter flooded roadways, “Turn around, don’t drown.”

Showers and isolated thunderstorms are possible Wednesday night and Thursday across southern Wisconsin. Any rain that falls over the next few days will only make the flooding situation worse.

In addition, temperatures will remain above 50 degrees until Thursday evening, meaning any snow that’s still on the ground will continue to melt.

It also will become windy Thursday. Winds may gust to more than 40 mph by Thursday afternoon, especially over southeastern portions of the state. A Wind Advisory is in effect from 10 A.M. to 7 P.M. for areas southeast of Dane County.

As a cold front sweeps across southern Wisconsin late Thursday night, some snow could mix in with the rain to start Friday morning. No impacts are anticipated with this round of precipitation.

The weather will turn quieter starting on Saturday. The upcoming weekend will be the first weekend all year without rain or snow. Temperatures will be a few degrees below normal under mostly to partly sunny skies.

However, even though no precipitation is expected, flooding may still be an issue this weekend as rivers crest Saturday night into Sunday morning.
