I hardly know what it means but I agree 

I'm no expert, but that EPO ridge is delivering cold directly from the Arctic, and that TPV near Greenland is serving as a kind of confluential [made up word] block. Looks like there might be a hint of split flow, too, so there would be good moisture coming in from the southwest up into that cold, and since we have the confluence over the Northeast, disturbances would be unlikely to cut.

True, a lot of moisture. But, as always …C8D088EF-9C88-42FE-973D-A21C9F13FA82.thumb.jpeg.aa5e54753d839ea9117a2274db61b8ff.jpeg

That map is pretty useless anyway for the purposes of the ultimate objective. It's the total precip depicted to fall over 360 hours on a single an op run, and much of it in the MA would be rain that falls between tomorrow and the end of next week.

So you're saying it's not going to snow? :(

@mattie g @nj2va and @brooklynwx99 thanks for the explanation. I understood it was a good look based on the ridge out west and the dip out east but thanks for the more in depth explanation. Always trying to learn a bit more to be a bit less clueless. One thing I would like to ask: how good of a sign is this for storms and whatnot, and what could make this look better or is it already near a realistic perfection.

it's a good sign. there's pretty notable split flow, so this ups the risk for phasing scenarios and general storminess with the northern and southern streams mingling

Gfs has a temporary 50/50 low at hour 180

So that's why that high never really moved, I was wondering what was going on. The setup looks interesting, the freezing line never really moved that much until the low was on the same line of height as Pittsburg. It almost 200 hours away so lets see if the storm is still there the next run.

Mhm, better cold press and a stronger HP overtop compared to previous ensemble runs.

This has been an error in the GFS/GEFS at range with recent events, so lets see how the trends play out over the coming days in comparison with the Canadians and the Europeans.
