GFS still pretty weak with the thump down here. I’m leaning toward that solution and not really buying the large NAM amounts. There’s just not a lot of vort energy that curls up into us until later when we’re already too warm for snow…and even when that happens, it’s strung out vort energy. 
 

Of we get a slight bump east or a slight increase in confluence, that could change but for now I’m leaning in the 1-3” range.

Both would help many, I've been looking for some of those small changes, So far not the case but the messenger rule may come into play the next 24-30 hrs.

Seems like most of the mesos are a little better than the gfs, but not like the nam

Yea, I think 1-3" is the way to go.

Yeah HRRR and RGEM were more like 2-4” (maybe a little higher up by you)….There’s some synoptic stuff I don’t love about this one if we’re trying to slam 4-6” in 6-8 hours. Usually want to see a nice broad area of isentropic lift well out ahead and it’s kind of meh…NAM does try for a narrower area and it’s fairly intense, but I hate relying on a thin band. 
 

A little shift east or slight increase I confluence would probably do wonders.

They issued a WWA for last storm, when 8+ looked inevitable, which it was. Now they issue a Winter Storm Watch when 4 or less looks inevitable.

Get with it!!

NWS changed there criteria for winter storm warnings for coastal areas and elevations, i Believe its 6"/24 hrs for coastal and just inland and in foothills and higher elevations its 8"/24hr period that it has to fall into to meet warning criteria, Outside of those windows, Its WWA's.

This is for the Berks (8 for WSW, less if ice is part of forecast, which it's not in this case -- snow to rain).

Seems like the main issue with this storm, at least up here, is logistical.  There was a lot of blowing snow last night so the driveway needs to be snowblown again.  That is a long process because it is a long open driveway.  Then we get the dump from probably 5p-midnight?  6-10 inches fast?  Then on top of that, in the middle of the night, sleet and then rain.  Then everything freezes hard Thursday late afternoon evening.  Seems we have to hope most of the snow is done early enough to snowblow it away before the rain comes and then it freezes into chunks.  It is hard to remove slush with a snow blower.  Any sense of how much rain we are getting in different parts of the region?  Maybe we drizzle and slot at least in some places?

In the end we should have a bullet proof pack compressed to 15-20 inches, fields to forest.

Many a night removing snow right before the rains came. Nothing worse than trying to remove waterlogged cement

This is what our mets went with pretty much. They did really well in the event yesterday I thought.

Have not read anything about an issue with this run.

Just as i said that

Investigating - Due to issues at the ECMWF, dissemination of the 12z Euro Op is delayed.

We will begin processing the data as soon as it becomes available from ECMWF.
