LOL - it's COLD. by 03z...it implies flakes for almost everyone where there's precip left.

Yeah real cold. It looks like when the model sows good VVs..the solutions have gotten colder. The idea is credible, but not sure how the boundary layer reacts from BOS on se. I suppose if we have nw winds, I could believe that...if the VVs are going to town.

Odds of 1" imby....30%ish imo.

Yeah the NAM has definitely trended stronger from 6z. Good sign.

Not sure when things will flip, but the 0* 850 is on my head at 15z tomorrow. Not sure if I'm doing the math right, but it looks like .75" comes down after that? Must be doing the math wrong--of course it is the NAM so maybe not.

40.1/39

It''s not all about H85....surface factors in, too.

still tough to buy a solution *that* cold. it has sub 530 thicknesses thursday night and friday - way way colder than the euro

That's why I said I wasn't sure about what it meant in terms of the flip. With regard to surface, I had been harping on the ground temps as a mitiating factor for accumulation since the weekend.

They're calling for highs in the low 40's before dropping off. That drop off will be key. Of course, so will the high itself. The call for today is upper 40's. I'm now at 39.8/38. A good bust on temps tomorrow could be significant.

Well, I was only referring to that one post....didn't imply you weren't.

Yeah agreed. I don't think I'll have 526 thicknesses tomorrow night. The NAM is more of a concern for these parts as the high elevations will defintely change over. I could envision a 34-35F flip to wet snow flakes for an hour or so around here. Maybe a crappy coating if I'm lucky.

Yea, that sounds reasonable.

I think 1" is my ceiling.
