September's off to a showery start

September's off to a showery start in Minnesota, with rain on four of the first five days of the month. Southern spots like Zumbrota and Faribault saw more than 4 inches of rain in a single day.

MPR News host Cathy Wurzer checked in with University of Minnesota professor emeritus Mark Seeley about the week in weather — including the colder temps (even frost!) that rolled in after all that rain.
