Powerful winds of the northwest will usher in air associated with the polar vortex to the densely populated metro areas of Boston, New York and Philadelphia. National Weather Service (NWS) offices are keeping a close eye on the weather setup and could issue Extreme Cold Warnings — rarely seen in the Northeast.
