Showers and thunderstorms will continue to pound Minnesota through the week, with the highest threat for severe storms and flooding existing through Thursday.

This comes as many Minnesota communities are attempting to clean up after recent storms, which brought heavy rains and strong winds that flooded roads, downed trees and power lines, and knocked out power.

The National Weather Service has issued a hazardous weather outlook for the majority of the state, which warns of possible thunderstorms that could develop late Tuesday afternoon in south central Minnesota. With this band of storms, large hail, damaging straight line winds and isolated tornadoes are again possible.

An additional 2 to 4 inches of rain is possible this week, the weather service says. Because of the already saturated soil conditions from the recent rainy weather, much of this week’s rainfall is expected to run off into the already swollen river basins.

The weather service continues to issue flood warnings for many Minnesota communities, including near International Falls, the southwestern corner of Minnesota and parts of central Minnesota, which have experienced significant flooding as of late.

River flooding is expected along the Crow River, Redwood River and Sauk River, while flooding is possible along the Mississippi River and Minnesota River. Urban areas and small streams could also see flooding, the National Weather Service says.

What's causing the unsettled weather trend this week? Paul Douglas wrote on the Star Tribune's weather blog that a warm front has stalled over northern Iowa, which makes way for thunderstorms to continue developing throughout the Midwest.

Douglas notes that skies will start to clear on Friday, although there will be a chance for isolated thunderstorms this weekend. The good news? He's forecasting a drier, less humid week next week for the state.
