A drawn-out storm pattern will keep much of the country active through the first week of April. A slow-moving front stretching from the Great Lakes into the Plains will separate late-season snow and ice to the north from heavy rain and severe thunderstorms to the south. The setup brings the greatest impacts to parts of the Midwest, Ohio Valley, Southern Plains, Mississippi Valley, and eventually the East Coast, while the West sees mountain snow and then a warming trend heading into the weekend.
