First, Phil saw his shadow this morning at Gobblers Knob in Punxsutawney, PA. As the legend goes, this means 6 more weeks of winter. As reality goes, Phil is batting about 39% which bodes well for those that want this winter over.
On to more important things, we have a storm heading our way which will move in during the overnight hours. With temperatures today approaching 50 degrees, we will be relying on a cold front that will be pushing through and dropping temperatures. How fast this can get through the area and how fast temperatures can fall will be determining factors on how much total accumulation we will have. The fact that the storm pushes in during the early morning hours will help the snow cause.
As of now, I think precipitation moves in between 5am and 7am across the C NJ area. Precipitation may start out as a mix but I think it will quickly transition over to snow. The problem we will have is the upper atmosphere will be cold enough to support snow, but the surface may not be. So, until the surface cools enough to support snow, we will be looking at a mix. In addition, once the heavier precipitation moves in, that too will help to keep the column cool enough to support all snow.
As of now, I do think another substantial storm is bearing down on the area. There is two different ways I am looking at this storm. As I am thinking now, with a period of mixing to start, I generally like 3-6" from Philly through Trenton to New Brunswick with 2-4" to the north of there. If the cold front can push in and our temperatures crash a little faster, 4-8" from Philly to Trenton to New Brunswick can be expected. I still think north of there for NNJ, NE PA and NYC will see 2-4"/3-5"
Other areas- NE MD - N DE 2-4" if mixing to start 3-6" if all snow
DC - Baltimore, S DE 1-3" but there will be serious mixing concerns.
