Snow to spread from the Northern Plains to the northern Mid-Atlantic

Low pressure over the northern Plains will spread snow into the Great Lakes and middle Mississippi Valley Tuesday, according to the National Weather Service (NWS).

By Wednesday, snow will expand into the Ohio Valley, Mid-Atlantic States and northeast. Out west, another front will bring heavy snow to the southern Rockies Wednesday. Freezing rain is possible in west Texas.
