Weather Summary for northeast Minnesota and northwest Wisconsin
Date:  September 22, 2016

Another major flood event hit parts of Minnesota and Wisconsin last night with this one targeting the area from the Twin Cities on south and east; road closures, mudslides, cars submerged, record or near record crests on some area rivers down in southern Minnesota and in parts of southwest Wisconsin.

Here in the Northland it was mainly dry today although there was some drizzle this morning in parts of the area.  The trend has been for increasing amounts of sun from north to south this afternoon as dry air continues to filter south out of an area of high pressure which was over Manitoba Province this afternoon.

Highs today were generally in the upper 50s and 60s with a few locations from Aitkin and Pine River up to Grand Rapids and Hibbing close to 70 degrees at 4 PM today.
