Discussion: The most impressive remnant of the northern stream energy has moved through S PA and into SNJ this morning. This initial energy is now moving out into the ocean however the weak coastal cyclogenesis has begun near Delmarva. This weak surface low should pull away from the coast while deepening and could enhance a final snow band through the general SENJ area. SENJ coastal counties would have the best chance to benefit from this additional lifting. Best case scenario for these areas would be an additional 1-2 inches of snowfall on top of what you already have. If the coastal enhancement produces a less-robust final band of snow then perhaps just another half-inch to an inch.
Otherwise this remains a light event, especially for points N. I expect areas NW of I-95/NJTP to taper off first over the next hour or so. Points SE of I-95/NJTP could squeeze out a few more hours of snowfall whether light or heavy (dependent on final snow band concentration). Far SENJ points should wrap up by 2PM give or take an hour.
Lake effect/enhancement could produce isolated-to-scattered flizzards later today and this evening. The biggest impact of a 5-15 minute flizzard is reduction of visibility, not the quick coating they can throw down. Other than that we will stay bitterly cold through the rest of the weekend and New Years. I’m still watching the Jan 3-4 winter storm signal and will be ready to discuss in-detail tomorrow.
In English: Snowfall has spread throughout New Jersey and should now taper off from NW to SE over the next few hours. SENJ has the best chance to squeeze out another inch or two should the coastal enhancement come into full fruition. Otherwise an additional coating to an inch is likely on top of what you have right now. I’m still watching the Jan 3-4 period and will fully report on such tomorrow. Have a great day and please be safe! JC
