Going into Feb gradient patterns are concerning. Might be great for Boston but cold rain/sleet here. It’s also still a Nina and Feb Nina’s try to pump the SE ridge. To our south is naturally starting to warm up and that will have more of an influence. We’d really need a strong high or confluence to keep us on the cold side of any gradient. 

we will probably have just one shot to get it done, we need a February 2008 type 6-8 inch event.

@Rjay This is looking like a SWFE. These almost always end up being New England events. The GFS being the furthest south at this range is no surprise at all, it’s destined to adjust further north. These always end up moving further north as we get closer in time. Would not surprise me at all if this ends up being an I-84 north snow/ice storm with very minimal onset frozen to rain south of there. We’ve seen this play out time and time again over the years…..

It would be nice if 06z GFS verified. Shades of 94 on that run. Unfortunately ensembles are a lot warmer so I don't buy it. 

 

The NAO is also going to be positive as hell. Nothing about that setup screams big snow/ice south of I-84. No mechanism to stop it from moving further north in time

February will start off above average as the MJO travels along in the warm phases. After that the pattern will get colder.

you must agree with the EURO AI warmer solution - the GFS shows a snow/Ice threat here next weekend - no above normal temps plus Walt seems to also believe the GFS solution - he started a winter storm thread for next weekend

Good morning ..  ECAI is always variable til it locks (I dont think its locked yet) and so it's part of the thought process that I needed to account for in the thread presentation.  WPC already has a significant 30%+ prob of snow ice interior PA high terrain on D7.  Both EPS-GEFS had decent 1"+ 10-1 snowfall ratio NYC area for D7, while the CMCE is almost non-existent.  

Thinking that the pattern is favorable for an event, some of it snow-ice.  Would love all snow NYC but at this D7 post, not the likely solution based on all the info that I was able to review. 

In the meantime, don't be surprised at 0.1 snowfall Tuesday morning and again Wednesday morning NYC CP. 

Fingers crossed (mine anyway) that this is not a loser. I'm comfortable with this start. Failure is always an option but not likely in my opinion. Just how much of whatever precip type with qpf 0.5-1 inch range.  It could be two periods embedded in this 00z/1-12z/3 time frame. 

What I wrote a small group this morning at 530A: Next weekend Feb 1-2: Monitor for delays and cancellations PANJ northward as at least some snow and ice is expected. Timing and amounts uncertain but this is looking significant. No action yet but maybe we'll know more tomorrow morning.

We can hope for a February 2008 type storm later in the month, that was also an SWFE in a warm pattern and yet it dropped 6-8 inches of snow.

Not much to update from yesterday. Looks like we're still on track for phase 8 with delayed effects last week of February through first 2/3 of March. 

Also as Don mentioned yesterday, a negative PNA, as we get to mid-February, due to shorter wavelengths is not as detrimental to snow as earlier months.
