This should effectively move up the entire timing for everyone. Probably done in the city by 2 and most activity after that to the east

I don't think its a sustained enough NW flow pattern for it to really hang around long though or in high concentration near the surface. I think the worst of it remains west.

Stuff is trying to pop on outflows now from Brooklyn into Nassau

Sharp gradients in Nassau now..70-72 by Merrick Road...80 around the SSP...82-85 from there to the NSP then 85-89 north of that

Hard to believe it’ll be that strong. Last I checked the consensus on the ENSO models was mostly around 0.8-1.0

You need a stupidly odd pattern to really get a Cat 3 or 4 up here and even then its probably likely to be a warm seclusion type thing which many now think 1938 was. It has to be a case of a trof over the lakes interacting with a strong ridge where the system is pulled N or NNW because anything else will want to bend NNE naturally as it comes north and any storm which is near or touches the NC coast will usually weaken and be west of the warmest Gulf stream waters.

Its hard to say if the NATL SSTs are solely responsible for that change though, there may be some other factor we just are not aware of which is leading to it. I know many in the meteorology world argue that SSTs really do not impact atmospheric heights and that its an overblown theory...we see this in the GOA every year when the argument breaks out whether its the chicken or the egg

Will be interested to see if the Mets wimp out and postpone Thursday or not...models have not budged from a 4-6pm arrival on that front really which is late enough to not impact the starting pitcher but the Yanks canned opening day last year 24 hours out given the open date available as is customary...could see Mets just doing the same. I'm not sure why the Euro seems so enthused with convective potential relative to other models. I am not impressed with the instability overall

If we get a decent El Niño it’s highly likely October will average below normal but even summers can be below normal during El Niño here so don’t be shocked if one of June July august is

Could be dare I say some inland 80 plus highs late next week if ensembles are right and it’s not showery or overcast. That second part is a big if now

Those hoping for the Central Park record we need big time help right now lol. Unless we have a nasty bust on the short range models they’re gonna get 0.6 I think on a snow board with trees around

The HRRR at hour 18 is markedly less stupid over SNE with low placement than the 18Z HRRR run was at hour 22 so maybe its beginning to get an idea. I could see 00Z runs finally agreeing for the most part

What probably is going to happen is when this thing finally organizes tonight the 06 and 12Z runs will all finally agree and be similar

That NAM run would not be bad even down this way if we were like 5 degrees colder

The dewpoints are fairly good on the models tomorrow late AM into the afternoon...if somehow some way there is a steady light snow I think those areas will easily fall to 30-32 tomorrow afternoon...the DPs and air mass in place to the north with the last event did not have that

That 18Z HRRR was hilarious for ERN MASS...that would be quite a blown forecast

The bust potential across most of CT is really big with this because if the models are even slightly wrong on the idea of that secondary low signature being too strong those areas will probably get alot more snow

Well...this might tell you where the NWS is headed in their afternoon update for the Hartford area lol...

My memory is the RAP tends to have a west bias at this range

The HREF is again going too high...mean is like 2-4 near the metro but its been consistently bad this year after it was very good last winter

Yeah...I posted in the NYC forum how on 2/8/13 we were snowing heavy here with a surface low over Cape Cod at 06z. you can get a mass expansion of the snow shield in the window when there is a close off and full phase

The GFS was not exactly good either, it was sending this to Bermuda...it was more correct for the wrong reason

The good news is its due for an upgrade soon...the bad news as a poster said here last night is the NAM is set to be discontinued perhaps....its fallen behind schedule since the plan was for the HRRR to run to 84 I believe, but as we've seen the HRRR often has a major BL cool bias beyond 18-24 and sometimes even a midlevel one too

Yeah he's not wrong with his ideas. I saw that on twitter...I do not buy the huge snow shield the HRRR/3K have back into our area tomorrow at all. I understand what they're keying in on to have that but to me the system is simply closed off a tad too far east for that to happen...its not crazy though that maybe the N Fork of cntrl to E Suffolk and maybe places like HVN could get in on a decent period of snow in the afternoon tomorrow. The DPs are cold enough this time that no question on a N flow places could get to 32-33 and accumulate

I think where you are the HRRR/3k ideas tomorrow are not that crazy but the snows it shows back as far as SW CT to me are probably bogus as the whole evolution of the storm IMO is too sloppy to produce that degree of snow coverage
