I don't see any surprises though. The CF is about where I thought and temps are pretty much what I figured.

Temps are slightly colder than I thought...I had figured like 28-29F right now here with flirting with freezing in the interior CP...but about 3-4F colder than that. But I can't say I'm surprised. We said countless times to watch out for the cold drain from Maine with that high position.

Yeah as Will was saying its pretty textbook for the area N and W of BOS.

Was someone posting that there wouldn't be ice?

I wish the antecedent airmass were better as this would end up as several days of wintry weather. Tonight would have been a classic set-up even here.

Yeah I mean more like BOS being 28 or ORH being 19. Sort of what we were saying..but those typical things like being a couple of ticks cooler seem to happen as you said.

But I agree with you, with that weak reflection scooting east and such cold dense air to the north, any little pressure fall will keep the ageo flow from the northeast. Pretty cool stuff for you guys.

I think ChrisM or whoever was wondering.

You can tell there is a good dewpoint drain ongoing when the temp keeps falling and the dew isn't rising as much as it should. I've dumped down to 25F here now. Originally I was at 28/20 and now its 25/22. Usually the dew should rise about 2/3rds of the way to the sfc temp while the temp falls the other 1/3rd to meet at saturation...that's the very rough way to estimate it.

I wonder what Kevin has going. He should still be below freezing I'd think. I don't think he can hold on to it for too long but at least he has some wintry precip to get him off the ledge.

Getting back to your original post, it is a waste of a good high. If the airmass aloft could be a few ticks colder, it would be a 32F snow. I thought I could grab a little 34F snow, but I was too optimistic.
