Dec 16 Just a little change can make the difference

...WINTER STORM WATCH IN EFFECT FROM THURSDAY MORNING THROUGH
FRIDAY AFTERNOON...

* WHAT...Heavy mixed precipitation possible. Total snow
accumulations of 4 to 9 inches and ice accumulations up to
around two tenths of an inch possible. Winds could gust as high
as 35 mph.

* WHERE...In New York, Northern Oneida, Steuben, Schuyler,
Chemung, Tompkins, Madison, Southern Oneida, Cortland,
Chenango, Otsego, Tioga, Broome, Delaware and Sullivan
counties. In Pennsylvania, Bradford, Susquehanna, Northern
Wayne, Wyoming, Lackawanna, Luzerne, Pike and Southern Wayne
counties.

* WHEN...From Thursday morning through Friday afternoon.

* IMPACTS...Travel could be very difficult. The hazardous
conditions could impact the morning or evening commute.

* ADDITIONAL DETAILS...Snow and ice amounts will vary greatly
depending on location and elevation.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Monitor the latest forecasts for updates on this situation. Winter
storm warnings could be issued as the storm gets closer and
confidence increases.

I-81 corridor is the place to be for this one.  Either that or be over 1500' ASL.

Obviously I81 corridor is the place to be but I'm not placing all bets on the Euro 48+ hours from event when subtle changes could make a difference. I'm 80 miles North of NYC. Should I be ignoring these?

I'm certainly not saying it's over. Just looking less likely that any decent snow is coming out of this system outside of I-81 or higher elevations east of I81. The h5 isn't anywhere ideal for good snow with this and if this somehow bucks that trend I'm all for it. Personally I'm giving it until tomorrow 12Z before I throw in towel FMBY.

I would be happy with 2 or 3 and doubt it would be any more than that given the setup but I still think it will be more than the near zero that the Euro depicts.

Let's see where the CAD actually sets up, if as depicted here then it snowing before a slower changeover to slop.

18Z Euro says CAD is deep and real.

Seems to be trending a bit colder up here in the boonies. This storm practices treachery, snow, freezing rain, icing…the full complement of bad stuff.

Window has def seemed to close for this guy.

I have to drive to Boston Fri morning..how bad do you think it will be for that?

If this mid-level energy slides about 100 miles S/E of what 06Z Euro shows, then we're having a much better outcome with this storm for many folks on the board.  Hour 48 and that kind of miss?  This trajectory will create a warm nose very quickly for folks south or east of NEPA/NW NJ.

Do not believe you will deal with much wintry weather, but the rain will be heavy at times.

For the coast and areas just to the N&W of the City I agree, but members more N&W out toward NEPA and SENY should see a few inches. As I had stated earlier in the week, the CAD/-NAO is more-so protecting the cold in those areas than it is doing anything for us. The H5 pattern is simply not good enough for the coast.

I am going to say though the low level cold will be tougher to move than what is being modelled right now.  Inland that's not just going to move out of the way quickly.  It'll be stubborn at the surface.

Close call but just too tucked I guess. And still don't like these ocean temps for the coastal folks. But, I feel like we're getting closer. With each passing system the antecedent air mass is a little colder and the setup gets a little better. Maybe we're building toward getting all the right players on the field in time for Christmas. :-)

National blend of models snowfall prog.  Looks about right to me.

Thank you Frank! the Xmas party as at the New England Aquarium..so excited..

6Z EURO sees a CAD a litle bit more now as I showed last night in the map I posted.
Coast is toast sadly again but again its Dec and the ocean is warm still 51* is not going to aid in snow chances on a east wind on this but lets see what the 12Z suite of models have to say for NNJ and LHV members. Thinking a quick thump then a gradual transition to slop and then rain (yuck!).

Compliments of Qtown on 33nRain wx board

Not a bad call at this time:

EURO still holding onto CAD signal

FWIW the 12Z GFS mid-level low trajectory was a bit further S/E and it'd take another tic or two for I95.  Can't rule it out.

GFS says I am locked in and keeps the storm trajectory as I have been saying feeling the block more and seeing the CAD more, NNJ and LHV may not be to rainy after all, NAM coming around to this aswell. Time will tell but a much better look for NNJ and LHV, HV crusher as is NE PA!

GFS evolution of the system... it's really cranks the lid down on the CAD prior to storms arrival pic.twitter.com/4V9xbOUFlg
