Another round of heavy lake-effect snow is forecast for the Great Lakes through mid-day Friday. An additional 30 inches or more could fall in some locations, on top of the impressive amounts that have fallen already. This will result in very difficult or nearly impossible travel at times in the heaviest snow bands. The snow should taper off during the morning on Friday.
