Coldest air of the season hits Northeast, with wind chill well below zero

Temperatures plummeted overnight as an arctic blast moved into the Northeast.

Millions of Americans woke up to the coldest air of the season on Tuesday morning.

Temperatures plummeted overnight as an arctic blast moved into the northeastern United States.

By morning, the wind chill — what temperature it feels like — had dropped near or below zero degrees Fahrenheit in several areas along Interstate 95, including New York City and Boston. Meanwhile, parts of upstate New York and northern Maine were 30 or 40 below zero.

The frigid air produced blinding lake-effect snowbands in western New York and Pennsylvania. Up to 30 inches of snow fell in 24 hours near the tiny town of Osceola, New York, some 55 miles north of Syracuse.

As of Tuesday morning, the National Weather Service has issued alerts for wind chill and lake-effect snow in 10 U.S. states, from Wisconsin to Maine.

Temperatures are not expected to warm up much in the afternoon, with numbers in the teens for Boston and New York City, though the wind chill will still be close to zero at times.

The arctic blast is forecast to continue for the next 24 hours.

The wind chill is expected to be in the teens and single digits along the I-95 corridor on Wednesday morning, before temperatures rebound to near 40 and 50 degrees on Thursday from Boston to Washington, D.C.
