NEW YORK, NY – After a week of tracking clippers, snow along the Northern Tier and a resilient Polar Vortex, a powerful cross-country winter storm is slamming millions across the U.S. this weekend to add to an already busy La Niña winter.
The storm has been charging across the nation this week from Big Sky Country to the Plains, Midwest and now the Northeast’s Interstate 95 corridor on Sunday morning.
A Winter Storm Warning is in place in Philadelphia, and Winter Weather Advisories are scattered throughout the region, including in New York City, Baltimore and Washington, D.C.

A large swath of 3-5″ of snow is likely for major cities like Philadelphia and New York City.
Half a foot of snow is possible in New Jesey and throughout Long Island, New York.
The winter storm’s peak will be Sunday morning before quickly moving out.
The storm slammed the Midwest with snow Saturday, grinding travel to a halt due to snow in cities like Indianapolis and Cincinnati.
In Illinois, the snow led to extremely dangerous driving conditions along major interstates.
Illinois State Police said Interstate 55 was closed near Springfield, after a multi-vehicle fatal crash on Saturday afternoon.
Drone video showed the pileup on the highway, with multiple semi-trucks zigzagged across the snow-covered highway.
WEEKEND WINTER STORM TO BRING SNOW FOR MILLIONS ALONG I-95 CORRIDOR WITH BITTER COLD FROM POLAR VORTEX

According to the FOX Forecast Center, these areas along the I-95 corridor are forecast to see 1–3 inches of snow, with some localized spots in South Jersey and Eastern Long Island seeing up to 4–5 inches.

The storm’s wide coverage area will bring snow to the entire I-95 Corridor, with many cities seeing their first measurable snow of the season.
According to the FOX Forecast Center, places like New York City and Philadelphia have the greatest chance of seeing snow worth shoveling, and potentially plowable snow, especially in Philly.

HOW TO WATCH FOX WEATHER
Drier air in the north will impede on how far the snow shield will go, but 1-2 inches of snow can be expected in Southern New England south of Interstate 90, with higher snow totals closer to the south coast.
The last of the snow will exit the Jersey Shore, Long Island and the Cape Cod area by midday Sunday.
