95" in 30 days is not only the highest 30-day snowfall in BOS, but more than any 30-day period in any major city in the country. (BUF had 80" in a week in Dec 2001 but very little on either side; Orchard Park has seen more but BUF is a smaller city and the totals are banded mesoscale, not the synoptic 90"+ around BOS.) I think Sapporo has had a couple of 100" months, and it's probably the only large (2m+) city to have ever seen a heavier 30-day snowfall than that 30-day period in BOS.

I can’t remember who was asking but the report from Boston is that the Charles basin is pretty much fully frozen over. Looks thin and will probably not last through the grinch on Friday. But still rare for December.

This grinch may be weak sauce compared with other years (and certainly 2020). 00Z op GFS CADs NNE and some areas barely get to 40. Surface winds don't look that bad, either. On the 12Z and 18Z GFS, MVL is showing ~6 hours above 40, BML barely cracks 40. The ECMWF spikes both sites to 50 but not for very long. Compare that to the mega grinch: MVL was above 50˚ for 22 hours, and above 40˚ for 37! BML was 22 and 44 hours! At least that year we got to sit outside in t-shirts and let the winds blow he covid around. (Had there been snowpack, the 2015 grinch would have been worse, with temperatures pushing 70˚ in Vermont; but there was nothing to steal.)

It's [looks out window] still liquid downstream of the BU Bridge but was frozen upstream where it's narrower/shallower/less windy at least before the brief warmup/light rain (I haven't been across it in that area since). Probably too much thermal mass and wind to freeze that over without a couple of cool, calm nights, although the wind is probably cooling it nicely. I think the last time it froze in Boston in December was late 2017, but then melted out once that cold snap abated a few weeks later ("abated" being a nice way of saying "2 inches of rain at 60°"). The all-timer was 2015, of course, when it froze in early Jan and melted out on something like April 3.

The first 10 days of the month at KBOS are 38.5 / 24 / 31.3, and that's underselling since there were a couple of days which with "highs" in the 30s which occurred just after or before midnight. Coldest start to the month since 2007.

How quickly you forget Grinch 2020. 18-36 across CNE/NNE on the 15th to 17th, followed by a cold week. Then 2" RA at 55+ wiped it all out (and with the winds and dews even some manmade trails were scoured off). These are all snow depths; actual accumulation before settling was often higher. Woodstock Vt: 18"-->0" RUT: 18" --> 0" Peru, Vt: 31" --> 4" CON: 21" --> 2" GYX: 11" --> 0" Poland, Maine: 18" --> 0" PWM: 13" --> 0" Bradford, NH: 19" --> 3" Sandwich, NH: 16" --> 0" EEN: 18" --> 0" Newport, NH: 25" --> 2"

More for the Grinch to steal.

And that's after the GFS backed way off the torch cutter from its 12Z. At 12Z it was 55 in BOS and 40 all the way up to YQB. Now it's 45 in BOS and keeps NNE in the low 30s through the event. It does bring the non-snow area into the 60s on the 23rd (happy Festivus) though. Those with snowpack would keep it setting the stage for this. I could live with the 18Z GFS (the 12Z was less enticing) but would love to suppress/CAD the 23rd a bit.

You could say that. Or a fun "oh a TT jackknifed now it's a fun sit for four hours while they reopen the road"

DDH often has bare ground while four miles away as the crow flies up Route 9 Mitch has feet. Especially when there are lake streamers which lose their juice but then slam into the wall of the Greens. Route 9 between Bennington and Woodford can be ugly!

There's a reason basically no one lives there. And also why we have things like, you know, heat. People do live in Fairbanks which can wind up with entire weeks below -40 day and night. But it's not windy, so I guess it doesn't count.

By midweek it will be congrats RDU or ILM, probably.

06Z GFS giveth, 12Z GFS taketh away.

-SN near Porter Sq looks nice outside.

KBOS METARS tell the story: KBOS 042354Z 30017G32KT 10SM -SN SCT033 BKN049 OVC070 M02/M11 KBOS 050054Z 29026G47KT 10SM FEW060 M03/M21 A3012 KBOS 050154Z 31018G34KT 10SM FEW060 M04/M19 A3015 Squall comes through, dewpoint drops from 12˚F to -6˚F with the 47KT gusts, and then rises as it slackens off a bit. I live under the departure path for RWY 33 and can't really tell if the noise I'm hearing is the wind or the aircraft. It's a mixture of both.
