The main weather story through the weekend will be a large trough of low-pressure that will affect much of the eastern half of the country with rain, snow, and wind. Additional to new snow accumulations will mainly be in the 1-3 inch range though a few areas could see a little more in southwest MN, western IA, central WI, lower MI, and OH through today, then building east into western PA, southern and central NY tonight, and finally into northern NY, VT, NH, and ME throughout Saturday. All precipitation will gradually become scattered and continue through the weekend beginning in the Midwest and Great Lakes today and tonight, and then into the Mid-Atlantic and New England on Saturday. Mainly rain showers are expected initially from the Ohio River Valley to the Southeast and northward to southern New England today with a few storms even possible, but this will become light snow shower chances potentially getting as far south as TN, northern AL, and northern GA.
