Note snowfall has gone down close to the immediate lakeshore over the years, while locations inland have averaged more snow in recent decades.
This research also exhibits lake-effect snow bands are pushing farther downwind of Lakes Michigan and Superior.
But a close view indicates immediate lakeshore communities are trending down when it comes to snow amounts.
We examined season snowfall data of both Grand Rapids and Muskegon. The data was observed over two 30-year periods: 1961-1990 and 1991-2020.
Starting with Grand Rapids, seasonal snow totals between the two periods
increased over time.
Average season snowfall has been trending up in Grand Rapids over the last several decades.
