GFS is still wedging very strongly. It's def a bit more zonked with primary but that confluence to the northeast is strong, so once again places like ORH never crack freezing.

Front end snow was a little better than 12z too....the 12z run was pretty flaccid....moreso than the other guidance.

Nam isn’t much for you 

I'm not sure there is enough QPF that falls as straight ZR to make this a larger impact icing event. There will def be some icing, but it seems like mostly less than 3 tenths to me. I guess if we develop the secondary a little sooner, then maybe there's a narrow zone for more ala the Icon model. Developing the secondary sooner will also help sleet go further south too for longer before the flip....so it's hard to get high end icing.

Gfs today had 40’s up north of the pike. Not close to reality 

Euro was the warmest model for today over the past couple of days. Everywhere is gonna spike near fropa, but euro was blasting 40s by to CON by 21z on a 48hr forecast

Yeah it tried for 50s here I think at one point, lol. Most runs were more tame. But it can get a little happy with the erosion of CAD sometimes.

There’s def potential for good ice but I’d like to see QPF after the snow thump be a little stronger OR the CAD hold really tough at the sfc due to earlier mesolow. The euro had like 0.75-1.00 of QPF over about 18 hours there after you flip from snow to sleet…and if a lot of that can fall as ZR and accrete efficiently (either light fall rates or sfc temps in the upper 20s), then it gets a lot more interesting for something in the 3/8ths range.

Even so 0.25-0.5 probably won’t do the damage trick for you.

When you get near 1/2” accretion it sure does. Obviously above that is when it goes up even more. What I learned in the zr storm here 2yrs ago though.. is with that amount of ice on trees.. and you rip 50-60 mph wind gusts like we’ll see Monday.. it’s probably going to be a big issue for a fairly large area

And <0.5" of flat ice accretion isn't going to cause any widespread issues.

Yeah the wind Monday should be interesting.  Not sure it’s impactful but we’ll see.

Hasn't everyone explained it? Between QPF and lack of good winds advecting in some lower Tds, not sure how much damage they'll be. 

I still vividly recall Mets on this board saying that event 2 years ago would not have much zr and there would not be any power or damage issues. And obviously there were in a small area. I’m not guaranteeing anything. But I will be very surprised if there’s not some significant issues come Monday

at this point our best hope up here I think is probably a strong primary that creates a more intense WAA thump, maybe 6-8, then a crust and a dry slot

doesn’t seem that there’s going to be a wholesale change, but maybe some messenger ticks can help us

No chance its going to evolve into a pure snow event there.
