Persistent Storm System Brings Severe Weather to Northern Plains Sunday

As the weekend comes to a close, the threat for severe weather will continue to progress eastward bringing strong thunderstorms to the northern Plains.

The storm system responsible for the strong thunderstorms that brought heavy rainfall, flash flooding, hail, and gusty winds to Nebraska and Iowa on Saturday, will target a similar area this afternoon and evening.

According to AccuWeather Senior meteorologist Dan Pydynowski,"Upper-level energy moving eastward across South Dakota later today can cause thunderstorms to develop across central parts of the state including Pierre."

Storms will move across South Dakota this afternoon, however by the late afternoon and evening hours, thunderstorm activity will intensify.

Central and eastern South Dakota will be the first locations to be impacted by these severe thunderstorms, which will have the potential to produce heavy rainfall and gusty winds.

Rapid and heavy rainfall can lead to water pooling on road, as well as flash flood conditions.

Thunderstorms will continue to fire eastward by the late afternoon reaching Sioux Falls, South Dakota, and Omaha, Nebraska, by early evening.

However as the afternoon progresses, the threat for severe weather will shift from a dual threat of heavy rain and high winds, to a triple threat of torrential downpours, damaging winds, and large hail.

"These storms will then move off to the southeast in the evening and overnight hours, eventually impacting Omaha, Nebraska, and perhaps getting as far east as Des Moines southward into northern Missouri by the end of Sunday," Pydynowski continues.

The strongest of these storms will be limited to western Iowa, although heavy thunderstorms will creep eastward, before fizzling out with a few showers with intermittent rumbles of thunder for Cedar Rapids, Iowa, Madison, Wisconsin, and Chicago.
