Light snow is possible into the upper Midwest as well, due to a weak low-pressure system entering the region, the NWS said. Cold westerly winds will also lead to lake-effect snow showers downwind of the Great Lakes.
By Wednesday morning, an upper-level disturbance swinging through the Ohio Valley will produce the chance for light snow showers to develop in the Ohio Valley and northern mid-Atlantic region.
