As snow starts to move out areas in the U.S. the National Weather Service warns of “dangerously cold air” moving into the northeast Wednesday into Thursday.
Cold temperatures in the northeast are expected to get colder as most of the region could see it drop into the single digits before the morning commute. An artic front could produce wind gusts up to 40 mph by the afternoon.
Ohio residents are also expected to feel the big freeze as well as temperatures are expected to drop below zero with wind chills as low as 20-30 below zero.
Snowfall made morning commutes in Ohio slick causing several accidents across the state.

Temperatures in northern Illinois were expected to fall to about 7 degrees below zero overnight, with wind chills of minus 25 or colder, National Weather Service meteorologist Mike Bardou said.
He said people should stay indoors, if possible, and cover all exposed skin if they must go out because frostbite can occur within minutes in such extreme cold.
State police caution drivers to stock their vehicles with extra water, food and warm clothing.
Temperatures are expected to stay below zero in North and South Dakota. Schools throughout the state plan to cancel classes or delay them until the middle of the day Wednesday.
