A new round of lake-effect snow is happening as we speak across portions of the Great Lakes region as strong, cold winds move over the relatively warm lakes, which happening to be icing up. This Monday, light lake-effect snow is forecast for the northeastern part of the Upper Peninsula of Michigan and in northwestern and southwestern Lower Michigan. To the east, snowfall rates will be heavier in the bands coming off from Lakes Erie and Ontario. The heaviest looks to affect the Tug Hill Plateau. There is also a band of snow originating from Lake Huron, which may bring a light snow to the Buffalo area.
Monday night, the snow will shut off across the western half of the Great Lakes while it continues to fall in the Erie, PA area and near Rochester, NY as the winds gain a bit more of a northerly component.
Then on Tuesday, the snow will continue to wind down. Now in the morning, light snow is still possible south of Buffalo, but there is one band that will shift back toward the Tug Hill Plateau that will have some staying power. This band will likely persist through Tuesday night, so this region will likely experience over a half of snow given then 2 inch per hour snowfall rates expected.
