It keeps coming back to this. What will the reality be? Keep in mind this is still over a week and a half away.

It's just a model run, so nothing to get excited about yet, but Platty is in the 5-6 inch range on it. I'm just excited to "see" snow, even if it's only on a model!

I'm leaning towards that track getting pulled back a bit further west to fit more in with this model's bias. Maybe a bit more front-end mixing. But at least temps drop this weekend so northeast resorts can go all-out snowmaking. That would mean some good lake effect snows for you Scotty!

The GFS seems to be mirroring the MRF ensembles ambiguity but there's an indication that the NAO will be on the negative side if not more so. That's what this storm needs to deepen into a bigger storm rather than just continuing on out to sea.

One other thing to note is that GFS shows three separate weather events for the Northeast inside of a week from Wed Nov 28 to Wed Dec 5. SOMETHING's gonna happen!

That would be about as much lake effect as they got last year.

True, the NAO will be slightly negative which helps--after all, it'll be just about as negative as it was for last year's Snowtober storm--however, the transition to negative is weak during that time. I'd rather see it sort of snap into negative rather than go negative then flatline to the event. I can see a slightly weakened system sliding through rather than bombing out offshore. Another indication is the near flat flow across the US leading up to the event. The upper level trough, or short-wave (looking at the 500 milibar chart on both the GFS and Euro) slides straight across from the Midwest to New England. Probably too flat to get a strong storm--I'd like to see that curl in much further south.

I'm not trying to poo-poo what you're saying--I'm just offering a fun exercise in considering a few more variables. Yes, something will be brewing as colder air tries to edge in....probably a quick half-foot (give or take) event with a slider like this. It'll be fun to track over the holiday!

Thanks Abubob!

Not to be negative but its looking more and more like the NAO will be. The GFS is showing more "curl" here - maybe too much as the low is forming over land which could circulate the warm air in first but its still showing this as a big storm.

Another thing to keep in mind is the model run....off-hour runs like the 06 and 18Z are run off of old data....the 00Z and 12Z runs ingest new upper air sounding data. Try to compare the on-hour runs to off-hour runs to keep track of those changes. Just another thing to consider. We'll be watching the potential for the track to shift back a bit with some mixing with this. Still a ways out--plenty of time to soak in more data! :)

True that. I just like to post the ones that look like big snow. Reality will always tend to muck things up though. 8)

Still looking good for lake effect snow next week and a snow storm for the Catskills?

I hear ya! It's always good to track those from a long ways out like you're doing just to see the trend. The 12Z runs were interesting--Euro too. I haven't looked at much nor the ensembles but it does look a bit more interesting. Now let's monitor this trend to see how it hangs on to this solution. I'll be busy the rest of the day--if I don't catch up with you before then, Happy Thanksgiving!

Some stretched out lake effect Saturday is still in the cards. Still watching next week's storm--a favorable trend but will monitor over the holiday/weekend. Happy Thanksgiving if i don't catch up with you til then.

Last few GFS runs have the storm develop on the west side of the Appalachians. Not good news as this would mean more rain for New England.

So not much snow for the hills is south New England from the snow event on this Saturday night?

We were getting snow showers here is central NH this evening. How much did central NY state get Scotty?

As far as the "event" for Wednesday is concerned there seems to be no way to predict what track it will take. It seems it will definitely go out over water but - how far south or north? Too far south and it just goes out to sea. Still hoping but the cold air that we need so desperately is working against us but pushing the storm too far south. There's new hope for the 6th though. :dunce:
