A few weak pieces of energy will approach our region later tonight and Sunday Morning creating periods of snow. These pieces of energy won’t really phase together while over land, but they will transfer their energy to a weak low developing off the coast in the early morning hours. The most snow we observe will come from the two pieces of energy. However, the coastal low will also throw some snow our way, especially in New Jersey. There is not too much liquid to work. However, snowfall ratios should be upwards of 20:1 and the snow should have no problem immediately sticking to most surfaces due to the cold temperatures in place. So with this in mind, a coating to 3 inches of snow is anticipated across much of the region. There is the possibility of a more persistent band of snow developing which could produce locally higher amounts. The best chance of this occurring is in east-central New Jersey. After the steadiest snow ends by early in the afternoon on Sunday, some snow showers will remain possible. There is probably going to be some lake effect snow showers Sunday Evening, especially in the Poconos.
Two more clipper systems are expected. The first clipper should arrive late Monday Night with periods of snow and wrap up early on Tuesday Morning. The second should begin later on Tuesday with some remaining snow showers around for Wednesday. These will also bring a light accumulation of snowfall for most areas with again perhaps a locally enhanced area of snow.
Another system is possible on Friday. The models are not in agreement yet on where this system will be placed as it brings precipitation to the region. However, this one may have more liquid vs. frozen precipitation with it.
