It sure is cold out!🥶Wondering where this airmass originated? We have a model for that! This frigid airmass was over Northern Canada (in the Arctic) more than a week ago. It'll stick around this weekend before the next system brings in warmer air mid week. #NYwx #NJwx #CTwx pic.twitter.com/Torjnr9SkU
