Severe Storm Risk Tonight, Flooding Continues

A slow moving storm system that's been hanging around the upper midwest since Friday will try to spawn another round of severe weather this evening.  Scattered storms look to build to our west and move in during the 5-10pm timeframe.  As they approach SE Minnesota and NE Iowa, they are expected to strengthen.  Main risk with this next round of storms will be damaging winds, possibly as high as 70 mph.  However hail and heavy rainfall will need to be monitored as well.

 

Sunday's heavy rain was persistent over the same area for hours on end.  This lead to flash flooding and numerous road closures and high water as a result.  Radar estimates below point to as much as 6"+ falling in parts of Mitchell county.  Ground truth tells us many places saw 3"+ with some of the highest marks coming in around St. Ansgar of 5"+.  Here's a complete list of rainfall totals from our counties east of I35.

As a result of last night's heavy rain, several flood warnings remain in effect along and south of I90.  Hardest hit areas include Mitchell and Floyd counties which are enduring major flooding from the Cedar River.  For the latest river levels across the area click here.
