Frontal system/wind-maker, and then a slight window/chance for snow?

Introducing the frontal system for around next Sunday night/Monday (December 10th/11th) that could be a wind-maker, as I alluded to last night. Also, if all goes perfectly and we thread the needle, some snow can't be ruled out for around December 15th, even for Long Island, as some of the Euro ensemble members (10 out of 50) are showing; it's a LOW chance for now though.
