Many cities cut back on the amount of salt they purchased after a series of below normal snowfall winters. Piscataway isn't the only city facing shortages. There is a mad scramble to get more now. Lots of competition for it, especially with the widespread ice storm predicted in the south.
It is all going to be about how close that secondary low is tucked in to the coast off of NJ. Even a small move east or west will affect if/when we change over. Right now they all, except for the GFS, want to tuck that secondary low fairly close to NJ before moving away.
I definitely would prefer all snow, or just all rain, than sleet, or even worse, freezing rain. Give me 6" of all snow instead of 10"-14" of snow, then sleet or freezing rain on top of it.
From what can see on the forecast models, the secondary low being even 20 miles further south and east would likely eliminate any mixing issues from the NYC/LI/CT area. The cold air at the surface will definitely be very stubborn to get out.
I think the cold air will be stubborn to get out. That is a strong high pressure system, with damn low temps at all levels of the atmosphere, at least for most of the storm. GFS and Euro soundings both show temps in the teens or maybe low 20s at most thru the storm in the NYC tri-state area. It looks like on the Euro you would have to get to around the same latitude as Philly before being concerned about any mixing issues. Canadian looks to be the warmest solution, with the rain/snow line getting as far north as the south shore of LI.
Depending on the wind direction, do you think that even the mid 20's might be overdoing it?
The soundings I am seeing across the models are incredibly cold
