They are ok. Nothing amazing. We keep the -NAO until it breaks down during the 3rd week of February.
Aleutian ridge becomes more poleward too later in the month. Might mean more gradient but who knows. Past week 3 has the usual caveats.
Also an outside shot at an arctic fluff surprise for Cape Ann and Cape Cod Thursday night/early Friday after everyone else has finally ended. Would need that ULL to dig as far southwest as possible but some guidance is showing potential there.
Burrillville RI could be a nice spot too. All depends if an IVT sets up for a while. GFS says it does but other guidance a little more mixed on the idea.
Near the coast will struggle a bit. Prob a couple inches of wet snow. Interior elevated will do pretty well. That’s where we’ll see the best chance for some spot 4-6” amounts imho if they happen.
There is also an outside chance that Cape Ann and Cape Cod get some arctic fluff late in the game from that ULL diving in...that wouldn’t be until Thursday night though if it happens.

They have sfc pressure on there too, but the underlying shaded contours are H5 heights.
EPS looks pretty good too beyond deeper into February....we just have to avoid the PAC-shuffle cutter on 2/5....we might avoid it if that leftover block in Quebec can hold the line one last time.
Sort of...it dropped down from lake Huron....pretty steep SSE trajectory until it swung east....like Huron to BUF to ABE and then eastward south of LI and back northeast into George's Bank.
Yeah it doesn't drop the low to our latitude or below until well east of us. Otherwise it would probably make for an interesting surprise potential....but it just doesn't have the room to do it on this setup.
Might be a little tucked for the coast to be optimal there, but details at this time range are kind of worthless. The general synoptic setup is really good.
The key was the shortwave maintained it's integrity longer than guidance was showing at the time. It's not uncommon for guidance to squash a shortwave too quickly, even in the face of a block.
Well for a warning I think it's 6" in less than 24 hours or 8" for any amount of duration. So the duration only matters if it's greater than 6 but less than 8....my guess is we aren't getting amounts quite that high anyway. But can't totally rule them out.
