A little bit nicer on Wednesday; High around 60 with some sun

/Issued 4:47 PM CDT, Tuesday, September 27, 2016/

A sluggish low! Humid cyclonic flow with areas of rain along with cool temperatures continued today in most of northeast Minnesota and northwest Wisconsin on the back side of a potent low pressure system over eastern Lake Superior - This system will drop south and is expected to reach eastern Kentucky by Thursday, but after that the computer models show this system lifting back to the north, likely moving over the eastern Great lakes region once again this weekend - Although this system is forecast to return to the Great Lakes region this weekend it doesn't look like it'll be far enough west to produce any additional rain in the Northland late this week or this weekend.
