Could have quite a temperature contrast on Wednesday with potential for widespread 60s and 70s across Minnesota and Wisconsin, but much colder temperatures in the 30s and 40s are possible around Lake Superior, but this all depends on where a boundary sets up for the middle of next week, if it ends up farther north, then temperatures will be much warmer near Lake Superior for most of the day Wednesday as winds would be SW as opposed to a NE wind should the front setup farther west/south as is shown on the map below.
