Rain is expected later tonight into Tuesday across the western and southwestern parts of the Northland, while mostly dry weather will continue in northwest Wisconsin, the North Shore, Arrowhead, and the Twin Ports region.
The rain is due to a slow-moving upper-level system and a surface cold front tracking east from the northern Plains. However, as the system moves farther east, it will encounter a strong ridge over the Great Lakes and eastern Canada, which will effectively halt its eastward progression by Tuesday.
Looking ahead, a few rain showers could move through the Northland on Friday (Halloween), but it’s not expected to be a major rain event. Temperatures on Friday are predicted to range from the upper 30s to the low to mid-40s in the area.
As we move into the weekend, a clipper-type system could impact the region around Sunday, bringing a bit of rain and possibly even some light snow.

A sharp gradient in rainfall totals is expected on Tuesday, with amounts ranging from about 0.05 to 0.25 inches along and west of a line from International Falls to Aitkin. East of that line, there will likely be little to no rain, while areas around Brainerd could see upwards of half an inch or more.
There’s still a chance for some lake-effect rain on Tuesday near Lake Superior, particularly along the North Shore, but any rainfall in that area is expected to be minimal.
The weather pattern is currently highly amplified.
