The Northeast experienced a deep freeze earlier this week, sending temperatures into the single digits with wind chills below zero, but it's about to get even colder.
As we head into the weekend, a high-pressure system over Canada will shift to the south. That, along with a low-pressure system off the coast, will team up to pull in arctic air from the north.
That will set the stage for bitterly cold temperatures and dangerous wind chills to spread across the region once again.

Wind chills won't be too much of an issue Friday morning. The gusty winds will make it feel like the teens and 20s across most of the region, with areas to the south, like in Boston and New York City, experiencing wind chill values between 25 and 30 degrees.
What does the wind chill mean?
But as we head into Friday night, that will change. Northern New York, Vermont, New Hampshire and Maine will likely see wind chills well below zero. Caribou, Maine, and Burlington, Vermont, could have wind chill values of 20 to 30 degrees below zero or colder. Bangor, Maine, and Albany, New York, will also feel like it's well below zero.

Dangerous wind chills will expand farther south by Saturday morning, including in Boston, where it could feel like 10 to 20 degrees below zero. Even New York City could have subzero wind chill values.
Winds won't be as strong as we head into Saturday night, but subzero wind chills will remain across much of the area. Parts of New England will feel like 30 degrees below zero or colder. Boston will likely still feel like 10 degrees below zero.
Sunday morning will also feel bitterly cold because of the gusty winds, but not as cold as Friday night and Saturday. Caribou, Bangor and Burlington will still feel the coldest, with wind chill values between 15 and 25 degrees below zero.
