As arctic air makes its final push toward the east, rain is forecast to change to ice and then snow along the northern New England coast on Saturday. However, farther south, rain is forecast to simply end. Heavy snow is projected to diminish across northeastern New York state and northwestern New England, while snow showers linger around the Great Lakes. As the cold air moves in, areas made wet from the recent rainfall in the coastal Middle Atlantic and southern New England may freeze abruptly later in the day.
Much of the eastern two-thirds of the nation can expect cold conditions. High pressure will build east from the northern Plains to the Upper Midwest. Temperatures in part of the northern tier of the Central states may not reach zero. The Florida Peninsula can expect chilly conditions despite a return of some sunshine.
Most areas west of the Rockies can expect mild conditions and some midday and afternoon sunshine. The only unsettled area will be from Washington to northern Idaho and northwestern Montana, where rain and mountain snow are forecast. This precipitation will mark the start of a new storm that will spread snow from the Midwest to part of the Northeast states early next week. While dry weather is in store for Southern California, the last of the wildfires had been fully contained as of Friday.
FOCUS: Cold Snap Through Midweek
Arctic air will cover much of the Midwest and Northeast through the middle of next week, with temperatures averaging 10 to 20 degrees below normal.
