In a quick stroll through Twitter, man a lot of forecasters are disregarding the crushjob OP Euro run. I get it, certainly. But a lot acting like it's not a possible outcome (or even in the ballpark of possible). I think NWS Mt Holly telling NJ to expect a 6 inch storm. Seems like many are favoring the GFS here.

Certainly seems like a decent risk for a big part of NJ to get more than 6 inch at this point, but I certainly get the hesitation after 2015 and with a set up like this.

Conservatism is the way to go, especially this far out.  But they also complain that no one listens to them because this is a social media world now

Mt. Holly disco is conservative for sure.  Giving little love to the Euro.  OKX is more bullish.  Time will tell.  All options still on the table.  The s/w tops the ridge out west tomorrow.  I'm interested in 00Z runs tonight but really interested in the 12Z runs tomorrow.

I'd argue the end result was still a world away. We got a cleaner phase with the southern stream this run, but the Euro's solution actually takes a messy phase in stride - it strings out the southern vortmax and leaves more energy behind. We get the Euro bomb from a more aggressive northern stream and better upstream ridge amplitude.

Yeah 0z and 12z runs are always the ones to favor.

 

Highest skill scores in the NH

Lee Goldberg is already honking on this storm, saying the chances are getting stronger that this will be a high impact event for our area with two days of snowfall 60+ mph winds and lots of coastal flooding.

 

have to keep the viewers returning - advertising high impact this far out only opens you up to criticism if we only get a light to moderate event .....

better to be conservative with snowfall totals 4 days out and adjust as needed each remaining day

They’re in a tough spot. They can’t go HAM at this stage but then complain when people chase shiny Twitter forecasts.

Do you ever read their presentations? They’re god awful. I do internationally-based marketing and business development and I wish I could help the NWS. They’re making 1995 presentations in the 2020s.

optimism is better than pessimism.  Basically what he said is that all the models are trending towards a major impact.

The best thing this has going for it is that there is no chance of any mixing here

Yep, and this is endemic in the scientific community.  Communications is a huge issue in science and it's why we see society behaving the way it does.

This is very true, but it's also got to do with funding. But many people, myself included, don't have a good understanding of the science ( so I basically just trust the experts ) and I think, as the spouse of a scientist and the father of two in training, that the scientific community does bear some responsibility here, because they tend to lack patience with those who have trouble keeping up. Also science by its nature is ever evolving; so what might be time honored practice today could change tomorrow. People have trouble with that.

I thought this was interesting concerning the western ridge. The following is from the NWS Albany discussion: 

To add even more uncertainty to the forecast, Stony Brook
Sensitivity analysis developed through CSTAR research suggests that
the eventual track of the storm will also be sensitive to the
strength of the upper ridge that develops downstream of the trough
(as is usually the case with these large east coast storms). A
stronger ridge will be associated with a storm track further to the
west; this is seen in the Euro solution as well. Often, but not
always, models underestimate the strength of the downstream ridge in
the medium-range as they cannot resolve the diabatic ridge-building
due to latent heat release. With ample moisture from the Gulf of
Mexico, it is certainly possible that this trend will manifest
itself with this storm as well.

Correct- it is ever evolving and changing  and its dynamic nature reflects our changing knowledge, if anyone has problems with that they should just look at what our level of technology was in the 80s compared to today lol.  Where do people think all that new technology came from?  Evolving science of course.  Science and technology are intrinsically linked.

Congrats on the science family-- I bet they'll do better than the previous generation did.  I think the best communicators in science were guys like Carl Sagan, who were both professional writers as well as scientists.  Carl Sagan was exceptional at communicating science, maybe the GOAT (along with Isaac Asimov, who I would also put up there with him.)

love that Atlantic ridge for this one.

Saying 6+ is fine.  I remember that was the forecast for PD2 a few days before the storm.

 

6+ inches for this storm 4 days out - what based on the EURO ?  No guarantee of 6 yet maybe 2 - 4 - higher amounts east

GFS is also 6+ inches from eastern parts of the city on east.

It would be irresponsible not to make people aware of the dangers.  Underpreparing is much more dangerous than overpreparing.
