On the 12z RGEM, 20z is the time for the changeover at my house (850 temps plummet).  The accu. precip before that is in between 1.25 to 1.5 in.  When precip stops, I have 3 to 3.5 inches liquid equivalent.  I still think 1-2 inches of LE equivalent of paste is possible for the coastal plain after the changeover.

Based on the new data-we have to be careful...slight trends south and a bit colder......If this trend continues today with new data, this will mean a quicker changeover to snow in the northeast and to points east and may mean boosting totals a bit.  Far from etched in stone...but this is the way it looks like right now.

Big Time Heavy Wet Snowfall all areas west of the Hudson Valley/NY area to the east

Kinda still looks like $hit east..  ugh

Yeah nail-biter of a forecast... I don't think any model at the moment verbatim depicts warning level snowfall Bos-metrowest, but there are 2 huge caveats:

1) thermal profiles are at least partially underestimating dynamic cooling, and this is an extremely good scenario for that

2) potential to bomb out closer and longer stall, which is clearly still in flux within 24 hours of go-time

That high ceiling low floor again. Areas along southcoast bordering RI went from maybe 1-2" to > foot in 6z vs. 12 HRPDS run.

Yep. Always take the under. Hurricane Andrew could be rumbling up the Merrimack and I'd take the under on winds in ASH.

Euro gonna bring us all back to reality as we come off the NAM high lol....at least out West of the River anyway.  The Euro is gonna be a disappoitment for most if I had to guess...just my gut feeling.  

It is more than just the nam high. I dont like your spot though. I think its route 8 and west for the cooler column. 

I have no idea what the euro will do, speculating is just gobblydeegook.

I agree. Tossing all models that don't show snow is how we've run this event.....hence why the NWS isn't showing much snow because they know better.
