At least it should be an easy thread title change.

A few from the S VT backcountry, Dutch Hill

didn't take too long. Full coverage again and moderate snow.

might not be a bad thing if that lead surface wave that forms off the carolinas gets going a little

Finally accumulating on the ground now. If we finish without any grass visible I'll call it a small victory.

We're snowing pretty hard here but it's all rate driven to no surprise. Radar is a bit ragged unfortunately.

That moisture plume straight out of the BoC

gl to the Belchertown expats that have moved on to snowier pastures.

4.5"

Just shy of 1.5" in Btown

Will be keeping an eye on DPs tomorrow morning before getting too bullish on advy criteria for this part of the valley. But as of now, we not complaining.

Okemo is typically reliable for early season conditions

December 2010 was uber painful here with a big snowstorm in Boston on the 18th IIRC and a Mt Rushmore bust locally on Boxing Day. But the same patience grasshopper advice would have applied because Jan and Feb were wonderful. Edit- seemed like the big snow was the 20th in SEMA not Bos

62, mostly cloudy, breezy

Southern section just came through Wilbraham... gusty sheet rain but nothing outrageous. Northern portion of the line looked a little stronger.

I'm headed out for it too, and was debating between A Basin and maybe Mary Jane @ Winter Park

We have a radar in Cleburne and got a really close look... Decent storm scale rotation within the line indicative of small hail and reports of such have followed. But not much in the way of notable wind signatures close to the ground. My eyes are currently on E Arlington/Grand Prairie where the strengthening line is starting to interact with moisture streaming north.

47? Wow. CEF 27. Talk about radiators mounting up

what does the green contour in Hampshire county indicate?

As an aside, studies suggest that increased atmospheric moisture content as a result of AGW should actually enhance upward EP flux in the subtropics and polar regions, particularly in the winter.... That's the posited physical mechanism for disturbing the PV (or at least it used it to be). I haven't followed the literature closely enough to see how well the link between snow cover (extent or advance) and +EP flux anomailes has been established over the years... we had some anecdotal evidence of correlation but not what I'd call conclusive, and the physical mechanism explanation could have used some work as well. It also sucked when the Berlin site went down that you used to be able to monitor this stuff with. At any rate, I can't help myself and still check wave 2 plots pretty often through December into Jan, but I've definitely got the feeling that the whole thing is a secondary signal at best as I've watched winters come and go.

This is an admission against interest because I was involved in the development of the October snow cover theory at AER back in the early 2000s... but LOL @ blaming AGW for ruining it. Sample size ruined it. It's simply not a dominant signal. All else being equal and null then sure it probably holds some merit. JMO

The valley lowlands are a bit shy of peak color yet but the last two days have been absolute fall perfection.

Gorgeous sunny morning in the valley, though Btown is still socked in slightly higher up.
