Look over all the storm tracks from these amazing archives. Plenty examples of where NY got more than here and the reason why, storm tracks. The ave temp difference is mainly from NY not radiating on clear nights. Like last night for example, I was 37 and NY 50, hence the differences in average. On cloudy nights, we are usually similar and same with nearly all daytime highs. What makes the temps marginal in nearly all winter storms in our area, big or small, has to do with the track. Many times, just a 5-10 mile difference in any direction in track can mean rain vs snow. That is the reason why I reached 50 2x and they didn't. Not because on clear nights I radiate so I am colder.
