RGEM is 2-4" NAM is umm snowy Yea these op runs are having trouble...I think your set to do the best, I may be a bit Far East for this one as precip deteriorated quickly even on the nam, most of my precip comes Thursday, whereas the GFS doesnt even have the 2nd wave associated with the cold front Link to comment Share on other sites More sharing options...
snywx Posted December 5, 2016 Share Posted December 5, 2016 Upton leaning toward 2-4" for areas around 84 northward. Ive noticed they have been conservative early on this season. Just last night they were calling for primarily a rain event now they see the light lol Link to comment Share on other sites More sharing options...

It does hit a wall though. NE PA looks to do the best of all. SNE will be lucky to get 1-2" from this Link to comment Share on other sites More sharing options...

Hopefully mother mature realized where its suppose to actually snow lol Hopefully we get some nice snows down here too. Tomorrow looks very borderline for me, I think I might rain most of the night.

I would not be surprised to see 5-6" locally as jackpot areas. I do think it falls apart right when it hits the NY/CT border Link to comment Share on other sites More sharing options...
JerseyWx Posted December 5, 2016 Share Posted December 5, 2016 I think NW New Jersey will do pretty well like you said. 287 is usually the rain/snow line around here, so it'll be interesting to see how this one plays out. Link to comment Share on other sites More sharing options...

Irishmick9 Posted December 6, 2016 Share Posted December 6, 2016 Will tomorrow night be elevation dependent? I have gotten 2.5 here in Vernon Valley while top of hill in Highland Lakes have about 8 so far Link to comment Share on other sites More sharing options...

I have gotten 2.5 here in Vernon Valley while top of hill in Highland Lakes have about 8 so far Yeah, I'd say elevation will help out a lot, especially for us here in Jersey. The guys up in the Hudson Valley might get away with slightly less elevation as they have a little more latitude. Link to comment Share on other sites More sharing options...
Juliancolton Posted December 6, 2016 Share Posted December 6, 2016 1 hour ago, UlsterCountySnowZ said: Check out my write up on wave 2 for Thursday in the storm thread, gimme some feedback plz Nice analysis, I certainly hope that you're right. The one thing I'd point out is that you can't always judge where vertical lift will be just by looking at vorticity maps. Vortmaxes by themselves don't cause divergence... what you look for are areas of advecting vorticity which generally indicate upper-level divergence and vertical ascent. More on this here: http://www.theweatherprediction.com/habyhints/65/. When you compare the NAM and GFS z500 charts, the GFS has weaker vorticity advection over our region. The differences are a little bit subtle, but they become more clear when you go back to hours 48-54 (see attached frames). The NAM has two much sharper shortwaves phasing with each other, resulting in a more amplified trough initially. The energy on the GFS is quite a bit broader and less focused. The height field becomes pretty similar by hour 78, like you showed, but the strength of the DPVA will help decide our fate. I believe the GFS and NAM do present distinct solutions instead of just mishandling QPF, and given conventional wisdom, I think I'd side with the GFS if I absolutely had to choose right now. Should be interesting to watch! Edit: I neglected to check surface progs, but you can see the differences even more distinctly there. At hour 48, the NAM has a sprawling precip shield and falling sfc pressures over the southern Plains, while the GFS has higher pressures and almost no precip. I think the NAM is overdoing the potency of that southern shortwave. Link to comment Share on other sites More sharing options...

It also looks alittle slower getting precip into the area. Im still thinking 2-4" for the area. NE PA is prob in line for a good event. Link to comment Share on other sites More sharing options...

Juliancolton Posted December 6, 2016 Share Posted December 6, 2016 Wow, that kind of sucks. We always knew precip would have a hard time pushing north and east, but I thought I'd be able to squeeze a couple inches out of it. Link to comment Share on other sites More sharing options...
