It did a little bit, but not a lot, at least on the west end.
If you draw a line roughly from the tip of the Keweenaw to around Two Harbors MN, everything south of that line is pretty well frozen up. Perhaps not solid ice, but not going anywhere fast. East of the Keweenaw, there is a lot more open water. If you go east of the tip of the Keweenaw by around 20 miles and then drop southeast to around Shot Point (between Marquette and Munising), most of the lake east of that line is open.
Lake effect starts to have less and less of an impact on our snow totals as we work through March. So we will likely see less snow off the lake for the rest of the season, but it will not cause March/April totals to be too far below average. That would come courtesy of a quieter pattern for system snow settling in.
