A series of systems will affect the country through the weekend producing rain and snow.
First, a system will affect the Midwest today and eventually fizzle out later tonight as it gets into the OH/PA/WV region. Snow accumulations of 1 to 4 inches with some possibly getting a little more in southeast MN/northeast IA/southwest WI through midday, southeast WI this afternoon/evening, and southwest lower MI this evening. Mainly rain will be expected on the southern end of this area of precipitation for northern IL, IN, OH, WV, and southeast MI.
Next, another system quickly trails the first system beginning to affect MN late tonight, WI, lower and upper MI Saturday/Saturday night, and then into the Northeast on Sunday. Snow amounts will generally be light tonight through Saturday night around a dusting to an inch, then by Sunday widespread 1 to 4 inches for parts of NY, PA, northern NJ, and parts of southern New England.
Further south a front will be meandering around the South which will produce isolated to scattered showers and a few storms will be possible at times from east TX to the Mid-Atlantic and southward.
Finally, a much more significant system builds into the western US through the weekend and will bring widespread rain and snow to these regions with several inches of snow expected in the mountainous areas. Looking a bit further into next week this system will create a bunch of problems for the central part of the country with significant snows possible in the northern High Plains, Dakotas, MN, and WI with some potentially seeing blizzard-type conditions, and severe storms possible Monday and Tuesday in parts of the Southern Plains and low Mississippi River Valley.
