We are currently in MJO phase 8 heading to phase 1, which is supposed to be "good" for east coast snow storms right? But then to phase 2/3, which is no bueno for east coast snow.
I would have to stick my head out on to my balcony to find out if it is all snow by me, or if it is a mix of snow/sleet. But at 14 degrees outside, it is not worth it. Accuweather, weather channel both say it is all snow in Riverdale, NJ.
Possibly if that low is too close to eastern half of LI, especially south facing areas. A difference of 20 miles can make a huge difference, and that has to be within the range of errors on all the models.
