FOX Weather Meteorologist Jane Minar breaks down a winter storm racing across America.
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 through 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.

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.
Video from Springfield, Illinois from Saturday shows a multi-truck pileup along Interstate 55 as a powerful cross-country snowstorm drops heavy snow across the Midwest before charging into the Northeast tonight.
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.

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.
