TWo different and unrelated concerns have me uncertain:

1. GFS/NAM stop moving at all and we have mixing. Probably more than modeled, dry slot issues probably more than modeled. If this is apparent early AM I will cut totals Bos PVD SE.

2. IMO the 5h is going to jump 3-5 hours earlier than modeled. The low will also occlude faster. has the potential to really screw some on thw W NW fringe areas I did not label

3. If there is a trend east and if #2happens totals will need to be dramatically incease in EMA as 2' would be a common measurement.

Fact is we have no way of knowing yet but we will soon - within 6-8 hours.

I don't know how much the NAM/GFS are realistically going to move in the next 24 hours...maybe a slight 15 mile trend either way, but I don't think that matters too much unless you're right on the edge of the mixing line. I think this is pretty much locked down. As far as occluding faster, that's obviously something we'll have to watch, but I'm not worried about it really.

Just my opinion, wide open until we have a low to track and see what the deal is with strength/dryslot etc.

You shouldn't worry about it because you aren't on the n or w fringe.

BOX just tweaked its snow forecast map ever so slightly. It now has Martha's Vineyard going from .4 inches of snow to .6 inches of snow. It has New Bedford at 13 inches. This is a very sharp gradient over such a small distance. We'll see how it pans out. The biggest cliffhanger with this storm is the rain/snow line south of Brockton/Taunton/PVD and the pros on this site haven't been addressing this issue all that much today.

WRT GFS: I know I probably beat these to death but I find insite in these little numbers....the MAV snow numbers.

The Cape's are paltry....while BID is 4 plus 1 in the last period (nearly universal in the region in the last period..). Newport RI up to PYM...6 plus 1. PVD-BOS north and west, 8 plus 1. It seems to me that the model wants to mix up to PYM for awhile with worse tainting as one travels SE.

I think we need to wait to nail down the rain/snow line. In my experience, you almost have to wait until the line forms and then see how it starts pushing one way or another. If you see it jog violently to the northwest then watch out it could go far before stopping but if it only kind of wobbles a bit then it usually stays that way. There's really not hard core meteorology behind it, it just depends on how well you can nowcast it.

My best guess is that it sets up near Plymouth, MA and arcs north and east towards hingham but that should be it.

I am not convinced those areas go all the way over. I'll give you a mix at times but event that's not certain and plain rain seems unlikely to me for PYM/Hingham.

Well bed time now....gotta sleep good tonight...not sure how much will be possible tomorrow night. In Jan 2005 I stayed up to 1, get up at 7. Lots of heavy snow/wind before 1 and after 7 but missing 6 hours is tough...but in long duration events necessary.

I'm staying up for the Euro tonight. First time in a looong time.
