Sey-Mour Snow

some EPS snow plumes while we wait for 00z guidance

For the very little it’s worth, it’s by far the snowiest I’ve ever seen them even when you don’t include this weekends snows

Weeklies got even crazier. 6 weeks of this pattern -NAO +PNA (-Epo mid Feb) With a -10 F 42 day anomaly and tons of coastals.

Different mechanism . Thump then slot south . Lesser thump but prolonged period of snow with possible coastal enhancement north

There are a lot of signs that point to this being a very strong thump especially south of the pike.. extremely anomalous WWA setup . As is euro is like 9+ hours of 1-2” + rates around here..

To me this looks like a hellacious thump to slot for 8-12 hours then maybe we can fill in some more snow Sunday overnight into Monday. CNE and NNE may have longer duration. Moderate snow

Thursday 4am earliest I’d say more likely Thursday PM watches

The relative consistency run to run at 96 hours out is wild .. there are such small changes in qpf for all of the northeast if you toggle back the last 3 runs.

Euro is a good bit north of 6z

I mean we have a 12-18”+ storm for dc to Portland Maine and that’s a mid size snow storm . Wow these don’t grow on trees .. obviously more than 10:1 maps as meteorology tells you there’s a very good chance ratios will be higher than 10:1

also total precip maps add a good amount of lake effect and tonights qpf

For the insane rates we need another 100 mile shift north

Yes I think qpf amounts will tick up .. You are talking 12-18 hours of overrunning snow in an extreme setup, going to be some beefy rates, also if we get a few more ticks north, that will beef up qpf.. Could see this being closer to 1" qpf just from the overrunning.

Wow that's horrible.. You need to see a 30"+ burger, hits different - I've had that in 96 and 2013.. 20" a bit more common about 5 of those in my life..
