Two systems will affect parts of the country with rain and snow through the weekend.
First, a system will continue to move further into the Atlantic, but will still produce rain today in the Mid-Atlantic states especially before noon, and also some snow with a couple of inches of accumulation possible in southern New England.
Another wet spot will be southern FL where a frontal boundary will hang around and produce scattered showers and storms through the weekend.
The other system will actually track across Canada the next few days, but with a surface, boundary draped well to the south from the center it will still bring rain and snow chances to parts of the country. First to be affected will be parts of the northwest with rain showers in WA and northern OR, and snow showers in the higher elevations of northeast WA, northern ID, and western MT today and diminishing tonight. Precipitation chances won't develop again until this system gets north of the Great Lakes and brings a few light rain and/or snow showers to northwest MN, northern WI, and the western part of the UP of MI on Saturday evening. Chances will increase beginning overnight Saturday in the eastern part of the UP and lower MI, then moving into the Northeast on Sunday. Lake effect snow is expected in the favorable lake effect snow belts off of Lake Superior, Lake Michigan, and Lake Erie.
