NEW YORK - A long-duration lake-effect snowstorm continued to pummel the Great Lakes region after dumping 3-5 feet of snow in cities across New York, paralyzing travel as people tried to get home after the busy Thanksgiving holiday weekend.

This has been the first significant lake-effect snowfall of the season, and snow totals have been nothing less than epic in numerous communities.
The highest snowfall totals so far have been found in cities and towns downwind of Lake Erie and Lake Ontario from northwestern Pennsylvania to western and northern New York state.

The impacts from the historic lake-effect snowstorm have been far-reaching, not only because of the sheer amount of snow that fell but also because of the intense snowfall rates reaching up to 4 inches per hour, which overwhelmed crews who were relentlessly working around the clock to remove the snow and ice from roads and highways such as the heavily traveled Interstate 90 from New York state to Ohio.
I-90 had been closed along that busy stretch due to dangerous winter weather that had affected travel in the region.
HAMBURG, NEW YORK - NOVEMBER 30: A couple makes their way through lake effect snow to attend the annual Hamburg Holiday Parade on November 30, 2024 in Hamburg, New York. The Northeast storm that closed a 90 mile stretch of The New York State Thruway …
However, thanks to the hard work of Department of Transportation crews across the region, I-90 was first reopened to passenger travel late Saturday in portions of New York, and the highway fully reopened to both passenger and commercial vehicles early Monday morning.
Travel is expected to remain treacherous in areas still impacted by bands of heavy snow coming off the Great Lakes. Drivers are being urged to stay off the roads if possible, significantly slow their speeds, and leave plenty of distance between vehicles to ensure the safety of people out and about on Monday.
Dangerous travel conditions have been reported for days, with FOX Weather Storm Tracker Brandon Copic witnessing vehicles struggling to make it through the snow as it was falling.
"Honestly, it’s just chaos out here," Copic said on Saturday from Erie, Pennsylvania. "The trucks are going on roads they shouldn’t be going because the highways are closed, and that just leads to more cars getting stranded."
Copic said he spent hours on Friday trying to help those who became stranded in the extreme weather conditions. Copic also sent in drone video that showed stranded vehicles on Pennsylvania’s Route 5 near the border with New York that showed cars and trucks stuck in the snow.
"The trucks that are jackknifed up the road is what caused the gridlock," he said.
States of emergency have been declared in three states – New York, Pennsylvania and Ohio – and National Guard troops had been called up to help with the storm response efforts.
And it wasn’t just the snow that was making headlines over the weekend. The paralyzing lake-effect snowstorm also produced rare thundersnow and even waterspouts off the shores of Lake Erie.

A video shared by Copic showed lightning flashing in the sky as the snow fell in Blasdell, New York, and loud rumbles of thunder could be heard in another video shared outside the Buffalo, New York, area.
Similar to thunderstorms, thundersnow requires a significant amount of atmospheric instability, and in areas where the phenomenon occurs, snowfall rates can be exceptionally heavy.
Winter weather alerts remain in effect across the region, including Lake-Effect Snow Warnings from Cleveland to southwestern New York that will remain in effect until at least Tuesday morning.

Winter Weather Advisories also remain in effect for parts of central New York, including the Syracuse metro, where several waves of lake-effect snow will impact the area through Tuesday afternoon.
Lake Erie snow to continue Monday
The FOX Forecast Center said the primary band of snow coming off Lake Erie will sink back to the south on Monday, and the main challenge for forecasters is trying to forecast exactly where the heaviest snow will fall and how far inland it will extend.
The snow band is expected to remain close to the southern lakeshore temporarily, but a shift to northwesterly winds will likely push it farther inland.
Some areas could pick up an additional foot or more of snow, with the highest totals likely occurring from parts of Erie County, Pennsylvania, through Chautauqua and Cattaraugus counties in southwestern New York.
Travel could again become dangerous on major roads and highways across the region, including I-90, I-86 and I-79, which could become nearly impassable. In the heaviest snow bands, visibility could drop to less than a quarter-mile, and strong winds could blow snow that has already fallen.
Lake Ontario also impacted
The FOX Forecast Center said the intense band of snow coming off Lake Ontario has weakened and shifted south after dumping 65.5 inches of snow south of Watertown, New York, in the town of Barnes Corners.
The snow threat there has now ended, and as the winds shift more northwesterly, the attention will change to new areas farther south of Lake Ontario.
The focus will be on a stretch of Interstate 90 from Rochester to Syracuse, where snow bands could produce snowfall rates of 1-2 inches an hour.
That could make travel treacherous on that stretch of I-90, which hasn't seen too many issues during this lake-effect snowstorm.
Lake Superior, Lake Michigan communities could see whiteout conditions
The FOX Forecast Center said multiple bands of lake-effect snow will continue well into Tuesday in western and northern Michigan across areas downwind of Lake Michigan and Lake Superior.
The bands aren't expected to contain snowfall rates as high as what has been seen in Pennsylvania and New York but will still be heavy enough to lead to near-whiteout conditions and dangerous travel.
Cities like Gaylord, Michigan, have already seen historic snow totals. The 24.8 inches that fell in Gaylord on Friday alone vaulted Nov. 29 to the city's snowiest calendar day on record.
But the FOX Forecast Center said the main difference on Monday will be the shift in winds. The winds will have a more northerly component, which forecasters said will make the bands of snow coming off Lake Superior the most intense.
