Some areas of southern Minnesota picked up more than a month's worth of rain overnight as showers and thunderstorms moved across the state, meteorologist Paul Huttner wrote on MPR News' Updraft blog.

As of 5:30 a.m., rainfall totals ranged from 2-7 inches in parts of southern Minnesota, with the highest amounts in Kandiyohi and Renville counties, the National Weather Service says.

Normal rainfall totals for the entire month of August in these counties is about 4 inches, according to the Minnesota Climatology Working Group.

Some roadways flooded

Heavy rain Wednesday night toppled trees, collapsed walls and caused power outages in the area. Check out this map of storm damage reports, which includes dozens of heavy rain and flooding reports in an area stretching from Mille Lacs Lake south through the Twin Cities and the Rochester area.

Flooding caused roads in Onamia to be closed due to flooding, according to MnDOT's website. And the Star Tribune is reporting some roads in Willmar are impassable – 2-plus feet of water has been reported on 6th Street and two walls collapsed in the area.


More rain coming Thursday afternoon

The first round of rain is expected to move out of the area Thursday morning, but more storms are expected to develop this afternoon ahead of a cold front.

The National Weather Service says more heavy rain and a marginal severe weather threat are possible Thursday night. A flash flood watch remains in effect for much of southern Minnesota into Thursday night.


The forecast shows things will dry out on Friday, and we could also see some sun. Cooler conditions are expected through the weekend.
