As I mentioned yesterday, Suffolk has a freeze warning and nothing in Nassau. This seems to happen every year with the first freeze or frost. We will probably have a freeze tonight in parts of Nassau
.
NYC won't hit 32 until a cold enough, windy air mass moves in. Meanwhile surrounding areas will reach freezing on nights like tonight with no wind and radiational cooling.
Probably tomorrow night a freeze watch will be issued for Suffolk and not Nassau, even though the rural areas of Nassau will be just as cold as Suffolk. This happens every year.
