Though it's running a few hours late, lake effect snow is still expected to produce light accumulations along the shoreline today. Some slick spots and pockets of reduced visibility will be possible during the late AM commute / early afternoon.
We expect today's Lake Effect Snow to arrive along the shoreline around 7 to 9 AM, peak between 9 AM and 3 PM, then dissipate from 3 to 6 PM. The snow will be "off and on" due to the snow band waffling onshore / offshore through the course of the event, but during the most intense landfalls it could produce snow rates of up to 1 inch per hour. Accumulations on pavement and pockets of reduced visibility may occur during the late AM commute and early this afternoon for portions of eastern Wisconsin. By 5 to 6 PM this afternoon, we expect north winds to push the lake effect snow completely out of the region.
