Brookhaven National Labs (on Long Island) still has an average January temperature below 30 degrees. I think one reason why is the recording station is not at an airport or urban area but rather in the middle of a large open field. I am sure they get very good radiational cooling. 

January 22, 1961 Brookhaven hit a record low of -23 degrees. The same night Newark hit 5 above, Laguardia 9 above and Kennedy 13 above. Now that is some difference.

Here is their website for anyone interested.

we have a house in wading River just north of that. There is an interesting dynamic there with radiational cooling. You see it play out in FOK too.

 

That said, the overnight temperatures and humidity have increased in alarming fashion over the last 20 years in the same area. Particularly in the summer.

Yes I really brought it up to show how radiational cooling can really make a big difference at times, the difference between more urban and more rural locations. There is no doubt that all areas have been getting milder and wetter in our location.

Is it possible we fall slightly below the record of 2010?

The Pine Barrens is a great location for radiational cooling. But the temperature patterns are the same there across the winter months as around NYC. Faster warming in December and February than January.
