An intense lake-effect snow event is forecasted to hit the Great Lakes region, bringing with it heavy snowfall and challenging travel conditions. This weather phenomenon occurs when cold air passes over the warm waters of the Great Lakes, leading to the formation of narrow but intense snow bands that can result in significant snow accumulation in localized areas.
The snow is expected to begin Thursday night in areas downwind of Lake Superior before spreading across the rest of the Great Lakes region on Friday. The National Weather Service office in Buffalo, New York, has issued warnings about the potential for multiple periods of heavy snow and uncertainty regarding the exact locations and amounts of snow accumulation.
