Thought placeholder until the 12z comes out... GEFS mean doesn't even make it to 40n

Positive tilted trough building southeast, going to go neg too late, if at all.  Height lines dropping into it though. That 546 height dropping in as it goes through hour 150 is interesting.

850 temps and low placement decent too at 150.

It could trend better and further south over time.  We wait and see. 

Maybe this is the spot you want to see it in at this juncture, maybe the models are reaching the far northern extent and will start correcting south. We'll see.

Even by adjusting for an earlier transit of the storm at latitude

Why? Because that Artic Jet piece is not in the mix - it dives down in behind this. That has to change for MidAtl to get winter out of this

Little bit of a difference with the ridge 😀

yes, you can see it there in the original which has the ARJ piece already involved as oppose to now where it's actually still within the W ridge and shunting it to a negative orientation (where as in original it is posi tilt as the height re-rise behind the AJ piece)

GFS ensemble still holding on hope.

Ensembles don't have the primary low making it as far north before the secondary forms. That would be more exciting if there was cold air to hold in place. Mean still doesn't hit 40N which given the direction it's coming doesn't usually result in rain... sometimes nothing imby actually.

850s work for White Plains and north.

So close.. but yeah, maybe 10 miles south here, 10 miles south there and its more white for more folks.

Deer and bear on the NY/PA border will enjoy this tho.

NE special? Still 6 days to go, going to take a lot of trending in one direction for mid Atlantic. 

TBH. those things are not so special anymore.  If a New Englander walked into a Storm Store he'd ask for "The Usual, please"

BOX rarely has much to say beyond 5 days out other than "signals" and "hints" but today's write-up they go all out - strikes me as a concise summary of the last couple of pages here..

Quote
There remains quite a bit of uncertainty in regards to next Sunday
and Monday. Keep in mind this is 6-7 days in the future so this
forecast could change quite a bit over the next few days. A moisture
loaded southern stream shortwave/low pressure system will lift
northeastward towards the Ohio Valley. Meanwhile...some of the
guidance hints at a secondary coastal low pressure system
developing. There is not much antecedent cold air ahead of this
system and the upper level pattern +NAO/+EPO is not favorable
either. However...there is confluent flow up in Quebec along with a
potentially arctic low level airmass. Therefore...depending on the
track and how far south this surge of cold air gets will determine
the Ptype. Currently, the potential exists for rain, ice and/or snow
if this storm comes to fruition Sat night & Sun perhaps lingering
into Mon. This may be followed by a shot of very cold air.

Things haven’t been so special up there this winter. They cashed in on a couple there recently to get some base for skiing , but overall not been good, and wow their forums “melt” when it isn’t good. Fun to read actually 😀

If I could move, I’d be going to at least 42N at some elevation. I feel like that is about the line of guaranteed winter that has staying power. South of that it melts and comes and goes. Whites would be my first choice though. A big LES town would be cool too.

Hey-- there a few folks that live up here in the northern tier 🙂

More deer/bear than people in these parts, though.
