    The dry air issue has been discussed enough, but looking at the bottom of this radar view from KENX (Albany), you'd think LI got clobbered today:

    Fun stuff.

     

    Too bad we can’t shovel what falls at the 10000 ft or whatever level that radar beam crosses our area. :( 

    There was no crazy confluence here today but plenty of dry low and mid level air. Soundings were brutal and made it obvious those GFS snow maps were way overdone.

    9.5" in ACY as of 1P...makes it top 14 snowiest January on record and I think Bluewave indicated we might get top 10 snowiest day.  Right now #16 snowiest 24 hour snowfall in a climate calendar day.  

    All this means (for me): it was a big one for that area. 

    Still some mod to heavy banding in that area. Wonder if they have a shot at 12”?

    NW edge obviously dried out and SREF in particular was too far nw while the multiple model ensemble axis S+ did well (GEFS/EPS/SREF)...many reports 8-12" just south of DCA to near or just south of ACY.  

    GFS obviously has a problem drying out snow, despite its decent soundings. Even the drier NAM was too robust on the NW side.  Am thinking similar drying out problem with the EC.  

    Which leaves the SPC HREF best of the short range groups with its 00z/2, 12z/2 and 00z/3 cycles attached. 

    It was a grazer as initially threaded by Forky.

    As a planner-preparer for minimizing impacts, even though essentially nada occurred NYC, I would prepare similarly again.  The downside is far larger problem than the successful zero accumulation forecast.  

    It's a matter of all of us realizing that the gradient edges of ensembled, or operational cycles can be wrong and keeping that in mind as we anticipate.

    I'm sure we're in a far better place with the modeling than 10 or 20 years ago, let alone 50 years ago.

    Seems like the dry air really won out from Philly on north. It’s why it’s better to look at soundings which showed the dry layer than the overaggressive snow maps in most cases.

    So far this winter is reminding me of 2018-19, where one big storm slid just south of us due to bad luck early on and we came up with snake eyes the rest of the season. I think the highlight of the year was getting 2 inches of slush in late February.

    The March 2019 storm was a disappointment. I think at the end it trended north and many of us were supposed to get 6-12”, ended up with a few inches or slush while Boston got crushed.

    The 89 event models actually began backing off on the 00z run the evening before but forecasters were slow to react.  The 12z runs morning of 2-24 pretty much showed zilch but again they didn’t really give up on the forecast til 3-4pm.  ACY has had .24 liquid this hour lol 

    Wouldn’t surprise me if they end up with 12” down there. Very nice event down in S NJ.

    Thanks Walt.

    Interesting to see both the EURO and CMC show 4 to 10 inch accumulations in the tri state despite the low essentially riding the coast into LI. Even with the track the majority of the Tri state stays snow on both models.

    I think that last storm to produce that much snow with that type of coastal running track was December 30 2000 (just in track not intensity or speed).

    For all the snow we had last year, I think just one was all snow at the coast. The rest all had mixing in some part of it. If we have cold air going into the storm and the snow shield is heavy and not shredded we can pile it up fast before any changeover. The Dec storm last winter was something of a disappointment here since the snow shield went shredded and allowed the warm air to take over sooner.

    Ouch

    I suspected yesterday that the models may have over corrected north and we might see the shift back SE that often happens with these. In any case I’m starting to doubt many of us near NYC see anything at all. Dry air is holding up. Really a shame that this is a suppressed to crap system being pushed out to sea. Would’ve been a very nice event here-frustrating especially since this looks like a winter where our snow chances will be quite limited.

    My final post on this thread and for this evening.  The amounts you see where 4+...its going to be 2-3"/hour.  May have some TS+ 1/8 Mi. 

    This is the one in 10 chance from Mt Holly, the overall Winter Storm Severity Index - both collaborated at 3P this afternoon, the 00z/3 3K NAM snowfall as a start, and the 00z/3 HRRRX.  You want big snow, you go south and get there by 5AM.  Should be a 6 hour window of some embedded white out down in s NJ somewhere. I checked 18z/3 NAM soundings. It all looks quite good for all snow after 8AM.

    Thanks as always for your contributions here, Walt. Hopefully this can pull a rabbit out of the hat and bump north 50 more miles.

    Will take it, just interested if warm air will be a problem on immediate coast if this wraps up and in a bit.  I had around 43 water temp when fishing 6 miles SE of Barnegat Inlet today.  

    At least for NJ, no. Northerly flow is coming into the storm. There’s practically zero chance it tracks far enough NW to mix the coast over.

    Agree. Not having the NAM in a setup like this gives me pause. The mesos are all south...which is why im not expecting much

    Yep. Up where we are this likely won’t be a big deal if anything at all. Sometimes models over correct NW as well at this stage so it wouldn’t surprise me if it edged back SE a little to something like the Nam.
