Four different features will produce rain, snow, and a few storms in parts of the country the next few days.
First, A trough of low pressure will move east from the Plains today to the Mid-Atlantic coast through Saturday. Widespread rain and snow is expected today and tonight in the Plains and parts of the Mid MS River valley with coverage expected to decrease in coverage on Saturday as it makes it into the eastern third of the country as moisture will become limited thanks to a frontal boundary around the Gulf Coast. Several inches of snow could accumulate today and into early tonight in the central and southern Rockies, western NE, and northwest KS.
Next, a frontal boundary that will be affecting parts of the Gulf Coast and Southeast will produce scattered showers and storms across the south today, Southeast Saturday, and mainly north and central FL on Sunday. A few isolated storms could be severe with this activity today from east-central TX to north FL today, north FL and far southern GA Saturday, and an even lesser threat in north and central FL on Sunday.
Further north into New England a low-pressure system will meander around this region through Saturday afternoon/evening producing widespread rain and snow with several inches of accumulation possible across VT, NH, southwest ME, western NY, and parts of northern MA.
Finally, rain and snow chances return to MT< the Dakotas and MN through Sunday and Sunday night with some snow accumulations possible as a trough and cold front build south into these regions from Canada.
