The month of March began with the area covered in snow, and it looks like it will end with the area covered in rain.

The National Weather Service has placed Southeastern Wisconsin on a flood watch all day today.

WTMJ Weather Plus Meteorologist Craig Koplien said that the weather could worsen as the temperature changes during the day.

"It's possible that the temperature will turn just cold enough late tonight before the rain ends to have the rain mix with or change over to some snow," he said.

He also said that this is a small possiblity, and if it does happen it wouldn't be enough snow to accumulate in the area.

Koplien said flooding isn't expected in the cities, but people in the outlying areas of Southeastern Wisconsin should be cautious of high water.

"It doesn't look like we're talking about any flooding in urban areas, or at least not any major flooding," he said. "The concern is mainly along rivers, creeks and streams."

Koplien said small hail is also possible during the day.
