A trough will bring precipitation chances from the northern High Plains to the Great Lakes through the weekend. These chances begin in eastern MT and northwest ND overnight tonight as light rain/freezing rain or drizzle/freezing drizzle and continue east and southeast through the rest of the Dakotas and in MN on Saturday, and then make it into the Great Lakes on Sunday. Precipitation will transition to primarily snow by Saturday night and Sunday with some light accumulations possible especial in the Great Lakes on Sunday.
A more significant system will affect the eastern part of the country through the weekend as a coastal low strengthens off the southeast coast later today and moves north off the Atlantic Coast through the weekend. Rain, possibly heavy at times will build from FL, GA, and the Carolinas today northward through the Mid-Atlantic states and New England through Sunday. Breezy winds are also expected, but mainly closer to the coast. Widespread rainfall totals 1-4 inches possible with parts of eastern NC potentially getting 4+ inches.
