East coast storm targets our subforum Noon Sunday-3PM Monday 1/16-17/22 with significant impact potential for heavy snow/heavy rain, a period of gusts 45-60 MPH along the coast with possible coastal flooding Monday morning high tide.

GEM has a similarly intense bomb for the 17th, but a couple 100 miles further off the coast than the GFS run. Let's hope a similarly intense storm is still showing up on the models around Thursday. Would be exciting to track a real ol' fashion nor'easter :)

March 18 was the last time we had a true nor’easter. There is nothing like heavy snow and coastal flooding. March 93 while technically an inland runner was fascinating watching 12” slush around in the streets

GFS, GEM and Euro all have a deep low pressure system off the coast on Monday with the GFS crushing the area, the GEM not too far off and the Euro heading out to sea. Something fun to keep an eye on at least...

This is why you don't give up on anything a few days out 

That is what I was alluding to yesterday. There have been consistent hints in the ensembles about the potential built into this pattern.  It’s a matter of the models figuring this all out.  Now that the lead system (coastal going OTS late in the week) is getting out of the way they are starting to move closer towards a solution.

Having passed 24 hours of modeling, the diverse modeling/ensemble opinions remain undecided.  On the table, too many shortwaves, or not enough separation. Am leaving the thread as is... my thinking is to grow this into something substantial but I may be wish casting. So keeping conservative.

14th morning: I think e LI, e CT and e MA will see a period of snow (1/2-3") Friday morning followed by scattered midday north wind gusts near 45 MPH. What I think we'll see is the 12z NAM be much deeper at 78-84 hours which a much tighter gradient and shoots a period of snow up the FGEN zone on the northwest side of the bombing ocean storm.  I will wait til sometime this evening to start that thread if the modeling looks more acceptable for this NAEFS scenario.

The weekend-Monday affair looks like a moderate or greater snow event from near ATL to interior NC and VA.  This is only my opinion.  LOW PROB follows: What I'm thinking is that the two shortwaves crossing the central-eastern USA this weekend early next week merge-phase.  The lead short wave sets the stage ATL-NC to NJ Sunday with the following short capturing the stewing low off NC.  NAEFS is marginal risk here in NYC.

To have TWO bombing lows off our coast within 3 days is unusual and not the likely scenario, except that modeling a couple days ago was going for it and we seem to be in extremes cold season starting with the TORS in KY, w USA snows in Dec, I95 snows so far in JAN. 

Attached 06z EPS for Sunday morning...a westward shift.

Offline til sometime this evening.

Wow that's impressive

Seems like the GFS has been leading the parade so to say this month - maybe that upgrade they did not long ago was the real deal. For this weekend storm it was the first to take the storm directly south from Canada to the Gulf Coast then out to sea south of us. The Euro and the Canadian changed its output a couple runs later following the GFS solution. Then the GFS reversed course and gives us a major coastal storm the last 2 cycles. Lets see if the Canadian and the Euro start trending towards the GFS soon and the GFS solution stays basically the same. So IMO give the GFS the benefit of the doubt and also I am only describing the OP solutions not the ensembles !!!!! and here is a non-scientific output for you guys who don't like them

Walt just nailed the 12z NAM.

The 12z NAM definitely hints at a path to getting at least a little snow from both. At 84hr it looks similar to the 6z GFS at 90hr, maybe even slightly better. If that trof associated with the coastal really tilts and wraps up quickly, the heights can rise fairly quickly off the east coast. As long as the PV in Quebec doesn't dive towards Maine there should be a chance for the Mon. event.

the ICON mixes us with rain and cuts down on snow amounts in metro

That's not rain. Worst case it's sleet. TT doesn't show mixed precip. for the ICON. If it's not snow it colors it green. And it's usually too far north with the snow-mix line. That's very likely heavy snow PHL to NYC.
