2020 and 2022 yes, but 2021 was wet (especially down in SNE but even up north).

Yankee Publishing has a webcam which takes a static image every hour. They've been in the pivot firehose since the storm started at 1600', I assume they're north of 24" by now. Here's a GIF of the storm (missing the image from 0700).

Meanwhile Mount Snow is reporting 34"

Mixed RASN in Cambridge. "Chunky Rain" status.

Not even close. Most recent months have cracked 200 (with no threats that happens. Mehbruary indeed.) but last January’s storm was 406!

GFS out to 3/28 has a high in BOS of 55 … which would give March a lower high temp than Dec, Jan or Feb. Of course, the real outlier was 2020, when April had a high of 62, lower than any other month that year (or the preceding Nov or Dec).

One less hour of morch

congrats Mitch?

15 mb in 12h over CHH … it's not quite bombogenesis, baby, but it's going in the right direction.

NAM at 24h vs NAM at 72h.

06Z on Tuesday has gone from 992mb at 41.72, 70.14 to 1000mb at 37.11, 70.14. Just a 4˚/276SM shift south. ¯\_(ツ)_/¯

63˚ on 3/30!

A friend out in TRK had photos of the Auburn Ski Club building up on Donner Pass (right near the snow lab) from a few years ago where people were going in and out the third floor by the end of the season. Great photos on their linked Facebook. They build warming cabins on stilts and they're still drifting over (or as a friend says: "it's not a warming hut, it's a snow gauge"). They're up on I-80 so at the whims of the highway and it seems they've been closed more than open recently. They're talking of skiing until July 4.

Looking back at that; April 1 1997 reported 22.4" of snow on 0.65" of QPF and having shoveled that storm I'm guessing a lot of that snow didn't make it in the can because it was not, as I recall, 30:1 ratio snow.

GFS says congrats ACK.

ofc they spent most of the week selling it as a "historic" storm in the top 10 (to be fair, their top 10 is kind of weak sauce) and then it turns into a foot of snow. Only one poster who started this thread was doing that here. (And to be fair, the models were pushing 12-24 for a while, and it wound up at the lower end of that anyway.

Congrats Saguenay.

Technically that was in 2011. In October.

Some top-notch AFD writing out in MPX. Not quite “bombogenesis, baby!” Thought. A quick note before we dive into the upcoming system: I understand that this event will attract a larger audience than a normal forecast discussion would receive. With that in mind, some may struggle to understand probabilities and the statistics side of this discussion, but I`ll do my best to use layman`s terms when possible. I want to put this Winter storm into into context for the wider audience. This system has maintained remarkable consistency in model and ensemble guidance going back several days. This itself is a rare feat for any system. This storm is a high floor, high ceiling event. What does that mean? There are high probabilities (75 to 90+ percent) that many locations in our forecast area will see a foot of snow by the time it ends Thursday night. This would be considered our "floor" or the lower limit of the potential outcomes. We`ll call this the "if everything goes wrong" scenario. The "ceiling" or upper limit of the potential outcomes or the "if everything goes right" scenario. The ceiling for the entire event is around 2 feet of snow. In hockey, every team wants to draft a prospect that has a high floor/high ceiling because if they only hit their floor, it`s still an impact player on the bottom 6 of your team. But, if they can hit the ceiling, you`re getting a superstar type player that doesn`t come around often. You know the type. Back to the Meteorology.

More interesting is the temperature range in the past week. For KBOS, -10˚ to 57˚ , a 67˚ range in a week which has only happened three times before at Logan. Getting into the top 3 would require 69˚ which is certainly not out of the question: 74˚, Feb 1943 (when Logan recorded its lowest temperatures). -14˚ on 2/15, and 60˚ on 2/21. 70˚, Apr 1976. 24˚ on the 12th, 94˚ on the 18th. 69˚, Feb, 2016, -9˚ to 60˚ (and 54˚ within two days!) 63˚, March 2007, 5˚ to 68˚ 62˚, Jan 2018, -2˚ to 61˚ Three of the top six within the last 7 years …

Ha. Meanwhile on 1/31 the GFS had BOS >0. 12˚ bust.

Just drove to Lake Placid. Car read 0 at CON, -9 at LEB, -18 over the greens (Midd Gap), -9 in Midd, -22 in LKP. Heat did fine in the car. Heat in the motel, not so great.

This year's January Thaw was 31 days long.

Logan has gone below -5˚ 10 days, and half of those were Dec 1942 to Feb 1943. Anything below -5 is a once-in-a-decade occurrence (1942-3, 1957, 1980, 2004, 2016).
