I say we reach 100 pages by Wednesday, forget about in total

So what I'm hearing here is, unlike other synoptic setups of some past storms, is that the stronger the low the less tainting there could be?

People are paranoid because this is the kind of synoptic setup that has the potential to truly produce a historic beast... provided that all the factors (northern stream, southern stream, positioning of disturbances, high pressure interactions) line up just right. With models setting expectations this high this early, while the end result could end up being exactly what is modeled now, there will certainly be some movement with us being 5 days out. Getting 6 inches of snow as a max out of this system would leave the board majorly disappointed, while getting 6 inches out of a system that comes out of nowhere would be considered exciting.

If this thing ends up in NY/Philly like the abortion a few weeks ago the board is gonna lose it

Look at Mr. Ice Miser over here with snow left to melt

I wouldn't be surprised if, given the modeled strength of this upcoming system, if a good chunk of SNE got anywhere from a coating to 3" of snow just from the outer precipitation bands.

Likewise. Almost certainly will whiff, but if you took the NAM and bumped it 50 miles to the west that would be feet of snow for parts of SNE. Just an absolute conveyer belt of moisture

I think our best shot at getting a decent amount of snow from Friday is the system shooting to the North slightly faster than currently modeled. The NW high, with accompanying arctic air, will prevent the system from being tugged West and will in the end force it to the east. One major difference from prior runs in the 3z Nam is the northern flank of precipitation and low pressure advances farther to the North before getting forced west. A stronger system would definitely help with this, so unlike Monday's system we want this to become stronger earlier. If the shifts that would need to happen (still somewhat unlikely as of now IMO) happen, this storm will catch the general public off-guard big time. Even cape cod weather forecasts have little to no precipitation in the forecast for Friday/Sat.

Maybe we can get the best of both worlds out of this pattern, with a mild-medium thump on Friday for eastern areas, and a large thump from Monday's system for Western areas (which received little benefit from the system last Friday).

Apologies, I was looking and comparing the 00z and 12z from last night/yesterday. I do believe that just like with our last storm, the interaction of the lows is going to be crucial to determine the path of the storm, which will best be observed via nowcasting.

For what it's worth (which isn't much) the CMC also has a substantial West shift for Friday's system, and 12z coats a good chunk of SNE with 2-3" of snow, where previously the edge of precipitation was hundreds of miles offshore

06z vs 12z for reference

The whole system has been modeled as a mess of lows for a while now, if the eventual low consolidation is West-biased I could see an advisory-level event for SNE in the cards

Maybe he was talking about Friday? Significant west shift, though it's pretty late in the game for enough future shifts to make it an event

18z NAM at 84 hours is interesting. It's been consistent with showing this low for the past two runs

At least the EPS has shifted Friday's event to the West... still need a few more shifts

I've come to realize that since there is a 99.99% change nothing we say or think about upcoming weather in this forum will actually change the synopsis, I'd rather stick with delusional optimism than realistic pessimism. I get to ride the absurd wave of excitement leading to an event, coupled with (potentially) crushing disappointment. Much preferable to "meh" which life has too much of anyway. That being said, I'm cheering on a West shift >50 miles in the 18z suite

What about Sunday? All the other guidance shoots it so far OTS out to the SW that I doubt we would even get cirrus. Definitely favoring Friday, but maybe Sunday-Monday whiffing will help us down down road

How many of the EPS ensembles show effects from the storm Friday in NE? Still think that, versus Sunday, is where our bread may be buttered Also that warm signal at the end of the GFS is no bueno.. shows a coastal storm that literally brings rain to the entire region outside of Northern Maine.

There is a strong OTS risk for Friday, but man that would be one hell of a storm if it did come to fruition. An intense low, blocking pattern which slows it down on approach, and sufficient arctic air would have widespread 12-18+ across NE. We hope...

The last several GFS runs have a strong signal ~6 days out for a low pressure to form off the southeast and move northward while intensifying. Revent runs have moved it to the west and intensify the low by a greater degree. This is the 06z run for today, we watch?

Curious to see what the latest mesoanalysis looks like

Interesting seeing that middle area of low pressure closer to the coast.

What the heck is going on here?

Is it just me or is the 12z and 3z NAM starting off with the eastern low significantly more east? And deeper as well
