Over the next few days, northeast Minnesota and northwest Wisconsin will experience occasional rain, but the likelihood of heavy rainfall with this system has greatly decreased across much of the region.
It seems there will be two primary periods of rainfall through Saturday. The initial phase is expected during Friday, predominantly impacting northwest Wisconsin, eastern Minnesota, and the Twin Ports area, while northern Minnesota is likely to remain mostly dry. The subsequent bout of rain might take place late Friday night into Saturday morning, potentially encompassing a broader area of the Northland than the first.
The most significant rainfall through Saturday is expected in southern Minnesota, eastern South Dakota, and parts of western and central Wisconsin. These regions may receive 2 to 4 inches or more of rain by the end of Saturday.
