Parts of southeastern Wisconsin could get seven inches of rain Sunday into Monday, according to the National Weather Service.
"The greatest concern we're looking at right now is in the far southeast Wisconsin," said J.J. Wood, meteorologist for the NWS in Sullivan.
Localized areas in Milwaukee, Waukesha, Kenosha, Racine and possibly Walworth counties could see seven inches of rainfall, Wood said.

"That's due to this low-pressure system that's moving very slowly across the region," he explained. "Essentially, the rain is kind of just pivoting over the area as that low kind of spins just to the southeast of the region. And that rain is just going to pivot right around that low as we go through tonight and into tomorrow."
There is also heavy rain along and east of Madison, up to Fond du Lac, over to Manitowoc, and east of there, Wood said. This area could get between two and five inches of rain.
The rain is expected to continue into Monday across south central, southeast and east central Wisconsin, according to Wood.
It's going to be moderate to heavy rainfall through Sunday night. Monday could see pockets of moderate-to-heavy rain. Then, the rain will steadily wind down as Monday night approaches.
The weather service uses the saying: "Turn around, don't drown," Wood said. If a driver encounters a flooded road, they should turn around and not drive through it.
"You don't know how deep it is," Wood said. "It's best just to turn around and not drive through it ... You could get into deeper water, and get into a real bad situation real quickly."
Since moderate-to-heavy rain can reduce visibility, Wood also recommends that drivers slow down.
The rest of the week looks pretty dry, according to Wood. There's a small chance of showers in northern Wisconsin Thursday night into Friday.
