Sitting at my computer right now I can look out my window and see the ground covered in already over an inch of snow. I was just in Roxbury about five minutes away and the snow was only sticking on cars and mulch surfaces, but in Netcong the roads (including major roads) are all covered as temperatures have fallen below freezing. Elevation between the two areas is about 500 feet, and it really shows considering the temperature dropped 4 degrees during my five minute drive. Elevation like always will play a key role. Here is my snowmap:
Snowmaking anytime soon:
Even though it's snowing and below freezing snow making is currently not possible. It is 31 degrees right now in Netcong with 85% humidity making for a wet bulb temperature of 29 and 27 is required to make snow. Of course it will get colder over night and within the next few hours the wet bulb will reach the required levels and the snow guns could go on with marginal snowmaking, but tonight should make for good snowmaking. Tomorrow high temperature shouldn't get above freezing in most areas so snowmaking can go all day at the summit for Mountain Creek and then again tomorrow night. This will not be enough to open the resort though, unless they have some tricks up their sleeves. I personally suggest just blowing large piles of snow and leaving them untouched (not groomed) because it looks like a rain storm next week and temperatures above freezing. This will make less surface area over the snow and won't allow it to melt as easy if it was all spread out, then next weekend snowmaking will resume and that will be the cold shot that starts off the ski season in New Jersey.
