Tomorrow's 00Z GFS is faster and further out to sea with the weekend system/non-system than last run.

I'd just add that it is kind of a pathetic situation. We have strong gusty northeasterly winds, high pressure is cold and in almost a perfect spot, there's even a bit of an inverted trough. You'd think somehow we'd be able to squeeze some flakes out of this. There is enough room for a system to develop further west but it doesn't. And I don't think it will. Sad.

The weekend has not surprisingly trended into a nothing burger. We were trying to depend on a perfect +PNA spike in a perfect location with perfect downstream wave spacing and amping. A completely thread the needle setup…No -NAO and no 50/50 low and very fast northern stream flow, no southern stream involvement/phasing. It’s been doomed for awhile IMO

No it hasn't but it's not looking likely now. Still bares watching.

We’ll have a shot at 50s to around 60 at some point during the last week of December. Many outside this forum don’t consider milder weather this time of year doom and gloom since it helps lower their winter heating bills. But it isn’t the greatest if you are running a ski resort during the holiday period.

Taking into account sky conditions and or if its raining ? Difficult to get to 60 in Late December with lack of daylight hours also and trying to predict over 10 days in advance - the whole setup could change by then........

Wantage NJ 8s High Point about 0.8" snow in 1 hr ending 5A. 3.4" so far though settling snow depth 3.2. 31F. still snowing a bit at 5A. Frankford Township DPW 3.5" at 4A, also Sussex County NJ.   GEFS was TERRIBLE for this current event.  CMCE and EPS much better. 

Regarding Fri-Sat of this coming weekend... am pretty sure of a light snowfall and maybe stick for first measurable NYC.  Can't quite yet start a thread. I want to get to 96 Hours with same scenario but probabilistic has been showing the potential for several cycles. See attached  graphics from 09z this morning. Will go with CMCE and EPS for the coming weekend.

I foresee a bit of snow with entire I84 corridor Fri-Saturday followed by possible wind chill advisories either Sat night or Sunday night for much of I84 northward with as previously mentioned,  the coldest air of the season so far.  

 

WSSI-P graphics attached. Pocket of light blue near NYC is risk of a moderate event.  The more extensive graphic is the still low probability for a widespread minor impact event, with the lighter blue hues in MA-NYS higher probability.  Lets see what evolves but I am not dismissive. No further comment from me on this til tomorrow morning.

Wantage NJ (this part 3.4" final but I've seen northern Wantage 4.1.  My season total 7.5.  I'll take it.  This is actually a halfway decent start to winter out here. 

Elevation has been a big help with these marginal set ups since late November.

Agreed on the decent start to winter. Gave my grandson  new snow pants, jacket, and boots yesterday as an early gift, it's coming in handy today at least.
