Watching the squall come through from this webcam in Windsor, Mass. at Notchview: https://www.youtube.com/watch?v=T0keY9QYH54 If you scroll back to 12:57 you can see the vis go from clear to "can't see across the field" (the trees in the distance are <500' away, so basically 1/16SM). Video should work for the next 12h.

And reported 164" of snow depth with zero settling during the storm. I assume they were just glancing at the snow stake every few hours. If they were taking more frequent measurements, who knows how much snow would have been observed. I'd imagine there were some avalanches up in Tucks from that one.

BOS has stayed below 50˚ this month so far and no model has it anywhere much above 40˚ the rest of the month. Would be the first <50˚ Jan since 2009 and first month since 2015 (Feb '15 and Feb '13). Mean days >50˚ is 4 and mean monthly high temp is 56˚. So while it hasn't been frigid it has not been warm either. Assuming it doesn't go above 47˚ or below 10˚ the rest of the month (the GFS doesn't suggest this, the Euro thinks it might toy with 10˚) the range of 37˚ will be the fifth lowest range for Jan on record, behind 2001 (12˚–44˚), 2009 (6˚–40˚), 1955 (10˚–45˚) and 2023 (23˚–58˚). This is also why while it has been dry the ski areas are doing great because it's been cold with low dewpoints which is great for snowmaking (and they don't really like it down below 0˚ because of evaporation and stuff freezing real quick).

i was in Mont Ste Anne that week, we didn't crack zero between our arrival and going through Concord, NH on the way home.

This morning: PANC: 36, 3" snow depth, 1.9" monthly snowfall KMSY: 23, 8" snow depth, 8" monthly snowfall

5 in a row at BDL <20 (3rd longest streak behind 1979 and 1918). 6 in a row at BOS (second behind 1918).

Looks more likely than not that BOS will have its first Jan that doesn't hit 50 since 2009. Average monthly max is 56, previous recent below-50s include 2009 (40), 2003 (44), 2001 (44), 1991 (49), 1985 (45), 1977 (47), so about one year in seven.

Yeah per Google Maps looks like the bad driving is Campton through the Notch but once you drop a few feet fine, and then once you get past Fabyans and south through Crawford. Hope the nordic trails got snow and they groom it tomorrow morning … we're trying to thread the needle between SN.

Let's not get too carried away running towards the end zone here, Leon is still with us. Last year's Valentine's debacle didn't really bust until 24h before the event start … which would be the 18Z suite.

Real, and spectacular.

Going to sleep. Will know by the page count (currently 53) if the Euro has followed the NAM offshore or not.

Meme me up, Scotty.

It would be very 2025 for the NAM to score a coup over all the other guidance for the first time in the direction of "not a storm" rather than its usual excitement over storms that fizzle/miss.

GFS looks great for SNE/coastal areas (this is out to 240h). G

A rare year where the west side of the mountain has better snow than the east.

Nice little band here near KBOS. Was -SN but just glanced out the window and back to SN.

Hokkaido has as many people as the Boston MSA, with a slightly larger land mass. Still, Sapporo snow is ridiculous. They average 182" per year, a bad year is still 125, and a good year pushes in on 300. January 1981 had 107" of snow, which is slightly more, but really not that much, than Boston got in that period.

Metro populations here. Depending on how you count, Boston is 5-8 million (MSA vs CSA), Sapporo is 2.6m.

BOS got more snow that month than any other city of its size (4 million plus), ever, in history. Sapporo gets more but it's smaller. BOS also had its second-coldest month on record (behind just Feb 1934), second-coldest low max (39, behind 36 in Jan 1875), 43 days below 40 (second place 38), 15 days below freezing (second place, 16, 1961) and 28 days with a low below 20 (second place: 23). It was basically normal temps for Minneapolis, except with way more snow. It's also when I went walking on the Charles and people were afraid I pointed out that it is basically a lake and Minneapolis spends its entire winter on frozen lakes. (Also, when people said "but combined sewer outfall" I asked when it had rained or melted enough.) What was even more wild is how easy the melt was. Just a bunch of dry, warm days, very little rain until late March (one earlier storm in the 30s meant the snowpack mostly absorbed it) and no flooding. Just imagine what a warm March rainstorm with 3" of precip would have done! (I remember some worry about this.) I think the Charles melted out in early April after three solid months. Almost definitely the longest stretch of ice cover.

Was that the anafront that wasn't? IIRC the South Coast got pummeled but it never really made it past TAN.

Or CLT.

KBOS hit -1. And was sitting at 5.5" of snow for the season on 1/23 (half of which fell in November). So far, give me this Jan over anything in the past decade aside from 2022 and 2018 (and 2018 started out cold and snowy but was 60 by the 12th.

BOX was saying 8-12 for Boston at 4 a.m. on the 12th (the day before) and wound up with 0.1.

It was clear at the 12Z models that Monday that the event was going way south and Massachusetts would be a non-event, but that didn't keep a bunch of cities from declaring snow emergencies that morning (after the modeling came out) and then having egg (but not snow) on their face the next day.
