[Whiteout conditions from Marquette, Michigan from Tuesday morning] Cold Arctic air plunging across the Great Lakes is producing bands of heavy, localized lake effect snow. Alerts extend from Lake Superior in Michigan's Upper Peninsula to Lake Ontario in Western New York. By this evening (Wednesday), many areas will see at least 6" of lake effect snow. The bands are not expected to be widespread, but they will be heavy and intense at times. https://twitter.com/NWSBUFFALO/status/1204691610921062401 https://twitter.com/NWSGaylord/status/1204779113191329793 Arctic air has been dropping southward behind a cold front, now in the Northeast. A trough will move across the Great Lakes today (Wednesday), enhancing lake effect bands. Lake effect snows will diminish as another system approaches from the west, warming temperatures and changing wind directions.
