December 2025 OBS and Discussion

[donsutherland1]

New York City finished December 1-10 with a mean temperature of 34.1F (1.2C). That was the coldest first 10 days of December since 2007 and sixth coldest since 2000.

A quick look at the guidance shows that a light snow event (probably 1"-3") across the New York City area is likely on Sunday. Given how snow events have been challenging to come by in recent years, to some it might seem like a big event. Even the previously bone-dry NBM shows 0.12" QPF.
