Great Lakes Lake Effect Snow into Wednesday
[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.
An oscillating band of lake effect snow will continue east of both Lakes today, lifting northward this morning and then southward this afternoon. In addition, strong wind gusts will produce blowing and drifting snow that will create poor visibilities and driving conditions. #nywx pic.twitter.com/tjivmTUVq3

Lake effect snow continues today, but gradually diminishes in coverage and intensity through the day into the overnight hours. Winds will be quite gusty at times, which will lead to areas of blowing snow and reduced visibility. pic.twitter.com/qQqPO7qexX

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.
