(NEW YORK) -- A winter storm is moving out of the Midwest and into the Northeast on Thursday, dumping more than a foot of snow in some areas and leaving hundreds of passengers stranded.
As of Thursday morning, more than 1,200 flights have been canceled and nearly 3,000 have been delayed, according to FlightAware. The airports with the most cancellations and delays are Chicago O'Hare International Airport, Newark Liberty International Airport and Cleveland Hopkins International Airport.
Already, up to 13 inches of snow have fallen in parts of Chicago, while Detroit has seen up to a half a foot of the white stuff.
From Oklahoma to Maine, 25 states are under Winter Storm Warnings, Advisories and Watches. A Blizzard Warning is also in effect for Long Island, N.Y., and for coastal Massachusetts, from Plymouth to Cape Cod.
The storm is expected to clear out of the Northeast by Friday afternoon.
When all is said and done, total snowfall in the Midwest around Chicago and just north to Waukegan, Ill., could push 1 to 2 feet. In the Northeast, the highest totals will be from Albany, N.Y., to Boston and Portland, Maine, where some areas could see 15 inches or more of snow by late Friday morning.
New York City is forecast to get 6 to 8 inches of snow, while Philadelphia is expected to see 4 to 6 inches.
Once the storm wraps up on Friday, bitter cold air from the Midwest will move into the Northeast. Highs on Friday will be in the teens for major cities and in the single digits at night. From Philadelphia to New York City and Boston, wind chills will be below zero and near zero in Washington, D.C.
