Not very good in short term. It def kicked the operational’s butts though in that D3-5 period. 

Maybe that’s the take away. Good with the pattern in the medium range but not great with the details in the short range. If that’s the case, that would be a good thing to know going forward.

You want it to get it right in the shorter terms though.

Nobody is shoveling day 3-5 snow.

Absolutely but for meteorologists, and for very skilled and knowledgeable hobbies like yourself, you want to know which models to use at what point and in what context. So if that’s where the AI models are now then that’s where they are.

Seen plenty of tears from a bunch on here that you would probably need a pump instead of a shovel, Maybe now this will subside some.

TY, This is true, But we have many that are already decent in the mid term but very few getting it right in the short term.

That’s why I like them more for the extended and mid range. Granted that was an AI ens to begin with, but even with the “op” AI I’m still hesitant to use use them close in except for trends. Yeah, the coarseness tightens up as we get closer, but it hasn’t been to regular op gradients. But it’s a new tool and we’re all figuring out how to use it.

Yes but we just don’t use it in the shorter term since we have great short term models. If we can rely on AI as a solid tool for medium range, then that has a lot of value. 

[ORH_wxman]

Fwiw, I think it’s good to talk about it a lot because the more we all recognize and point out where the AIs were successful, then we can start to pick up patterns….maybe they are good in some types of setups and crappier in others relative to the OP guidance.

This was an absolutely confidence boost in taking AI more seriously in the medium range. Now, we can't assume that AI is just going to nail the medium range but the value this could provide is huge. Inside of 48 hours we just continue relying on the mesos and.

I still like 2-5" for SNE, srn NH, and coastal ME.  Now, will the rear weenie squall mesolow thingy push some locations to 6 or 7".  As CoastalWx always said to me years ago, "WE'LL SEE!" (implied optimism in his tone).  There is a distinct vort at 500 w/ this thing, and a clear twist/hook in the pcpn pattern as it gets just off Cape Ann.  If there is TSW+ in Weymouth? LOL.

Going back to ydy, 10.5" at Savoy MA for the max.  That is among the biggest synoptic snowfalls in SNE I can recall for such a "lame" sfc low/track (weak and well NW) and SW winds sfc and aloft the entire time.  It was screaming SW 30-60 kt 925-850 during the event, yet it stayed all snow.  Not just elevated areas either. 4" in Haverhill MA and 4.8" Old Orchard Beach ME.

So the piecemeal, piling on, lgt-mdt SN events continue this winter.  Ydy was it central and west, today will be central and east.  But CoastalWx still grumpy I bet.  "I want a KU to end all KUs!!!"  

The 1.3" at Marianna FL this morning, did it w/ nothing atypical for a pattern across the CONUS.  Fairly avg ridge/trough wave pattern currently.  FL had accumulated snow 2 years in a row March 1954 and 1955.  In Feb 2010, accumulating snow occurred twice in 3 days.

CoastalWx *not* happy about the "cold 'n dry, kiss'em goodbye" pattern after today the global model op runs show?!  But the GEFS gives hope for next weekend!  Does look like a nasty snow/ice event from the Srn Plains to SEUS.

I'm on the Haverhill line....3.25".
