Lake effect snow is expected to pound areas near the eastern Great Lakes on Tuesday into Wednesday -- especially just south and east of Buffalo, New York, and far northwestern Pennsylvania.
And a winter storm that caused post-Thanksgiving travel chaos and power outages has moved into upstate New York and some areas of New England, where it could drop up to a foot of snow into Wednesday.

Rivers, lakes and falls (by name)
Cold air is moving over the warm waters of the Great Lakes, producing lake effect snow that will be heavy in places. The highest accumulations are expected to be just south of Buffalo, where 15 to 20 inches is expected.
To the east, a storm system that plagued the Midwest will leave heavy snowfall in other parts of upstate New York and northern New England. This includes Rochester, New York (up to 6 inches); northeastern New York and parts of Vermont (up to a foot); central and northern New Hampshire (up to 9 inches); and Maine (up to a foot), the National Weather Service says.
The storm dropped heavy snow from Colorado and Wyoming, where up to 60 inches fell, through the Midwest, including Iowa, which got up to 17 inches. It hit the Chicago area hard, with more than 7 inches of snow, making it the strongest November storm since 1975 and the fifth-largest on record for the month.
More than 1,600 flights within, into or out of the US were canceled Monday, according to FlightAware.com. Chicago's O'Hare International Airport was hit particularly hard, with more than 1,300 flight cancellations and delays averaging more than 50 minutes because of heavy snowfall.
At the peak of the storm, more than 220,000 customers were without power in the Midwest, particularly in the Chicago area. Early Tuesday, more than 67,000 Illinois customers remained without power.
Kansas declared state of emergency
The storm disrupted travel for many on the last day of the holiday weekend.
Kansas Gov. Jeff Colyer on Sunday issued a state of emergency declaration, and officials said road conditions were "treacherous" in some areas.
More than 1,700 US flights were canceled Sunday, with delays to 5,091 flights, according to FlightAware. Most were at Kansas City International Airport and Chicago's O'Hare and Midway airports.
Multiple roads were also closed because of whiteout conditions, according to the KanDrive website.
There were reports of snow as high as 16 inches in parts of Iowa, with other areas reporting 3 inches to 10 inches. Baileyville, Kansas, notched 10 inches and 7 inches fell in Salina, Kansas.
