Back to -SN in Kendall Square. Vis about 6SM based on which hills I can barely see on the horizon.

-SN in Cambridge/Boston out the window (office in Kendall Sq).

DEM but then it occludes over the CAR CWA and sends a ton of moisture down the St Lawrence Valley that gets lifted up over the mountains. That's the kind of Green Mountain Special where Jay gets 4' but the Dacks and Whites would get some as well. The Mansfield snow take would get a nice bump, too.

The end of the 3k NAM looks similar.

For BOS 30 year periods back to when they started gathering the data at Logan: Dec Jan 1941-1970 32.9 29.0 1951-1980 33.5 29.2 1961-1990 33.5 28.7 1971-2000 34.7 29.3 1981-2010 35.0 29.3 1991-2020 36.0 30.2 2025/2026 31.3 28.8 So December was colder than any 30-year climate period, and January was colder than any climate period but 1961-1990 (colder by 0.1°). Feb will need to torch the end of the month to be much above!

The longevity of this is the story … Today was 9 straight days at BOS < 29˚, T-11th (most recently 2004 and 2018). The next couple days may well crack 30, but if the "warm" days this week stay below 32˚, then it will set the record (16 days, 1961, 2015 was second). Having a top-10 snowfall and then a cold stretch has only happened once before (2015). The recent <0˚ temperatures were very short-lived. 2016 went from -9˚ on 2/14 to 54˚ two days later, 2023 from -10˚ on 2/4 to 51˚ the next day. 2018 did manage to go below 0 during the cold spell. So, nothing too cold, but an anomalous pattern that is sticking around for a while. Now if we could inject some moisture into it with the right timing again …

8° at KBOS this morning, WC -11°. With the sun angle it didn't even feel that bad. (I think a lot of it is that we're kind of getting used to it.) Today is 6 days at BOS <30°. 9 is likely by Sunday, which would be tied for 11th longest. The record at or below 32° is 16 days. Neither the Euro or GFS has BOS breaking 32 through the end of the model, which if it verified would break that record by a lot. (Thanks goodness we got that storm last week or we'd have cold, mostly-brown conditions which would be miserable.)

YHZ gets smoked. Is there a Maritimes board?

Newburyport?

That and the BN after, keeping a nice, white, useful snowpack in place. Oftentimes we get 2' of snow and it's 45 the next week and gone into slush and puddles. The globals haven't shown a high much above freezing in SNE before Valentine's Day.

BOS is just-0.7, although they will probably wind up -2 by the end of the month. And Feb should start out BN enough it will take quite a torch to wind up AN. The string of days in the mid 40s to low 50s pushed up the average. MQE is -0.6. BED and OWD, which radiate well, are -2.5 and -3.2, respectively, and both overperformed last night, too (-8 and -15, although the latter at OWD didn't have an hourly reading below -9). With the snow I would expect this to continue, especially with some calmer nights coming up.

Pinkham Notch started out with 37" OTG, wound up with 50.

We need the DGEX to vote too.

I saw the same shooting star …

I love people saying things like "my weather app says 3-5" of snow on Sunday" and me saying "well the forecast should really be 0-36 inches with a bimodal distribution around 0 and 20" but apparently people would rather have wrong forecasts.

Congrats on the models that sniffed this last burst out. Really enjoying these echoes even if it's about to end. For now, at least, it puts a new layer of white onto everything. If we do it again in a week we're going to have 2015 levels of "where the heck do we put all this stuff?"

Massive hit on the CMC. 956 mb basically on top of the benchmark.

BOS was in the upper 20s for 10 hours from 1600 yesterday to 0200 today when the coastal front passed through. Might make it to 22 this afternoon but both days get a high of 29. Still a -10 anomaly of course, and 32 doesn't look like it's coming back for a while.

17 is higher than 8 or whatever it was before. BOS METAR from the front: METAR KBOS 252054Z 02010KT 1/4SM R04R/2200V3500FT +SN FZFG VV006 M05/M06 A3029 SPECI KBOS 252037Z 35009KT 1/4SM R04R/2000V2400FT +SN FZFG VV005 M09/M11 A3030 SPECI KBOS 252027Z 35008KT 1/2SM R04R/1800V2200FT SN FZFG VV006 M11/M13 A3032

Five hundred yards. That's the length of five football fields, just shy of half a mile.

Euro says nah

Alton Bay Ice Runway (B18) should be ready once the storm passes. They're at 11" right now, and need another 1-2" to open. Once they are open this year they should be open for a while. https://www.facebook.com/AltonBaySeaplaneBaseandIceRunway/

Record for days AOB 32˚ at BOS is 16 days … this will be close. Unlike the quick cold shots in 2016 and 2023 when BOS went to -9˚ and -10˚ it might not crack 0˚ but both of those went to 50˚ within a couple of days.

I'll see your Hibbing and raise you a an Ely (KELO), -38˚ or Cook (KCQM); Cook also hit -38˚ last night. Lowest reported aside from a -45˚ in Wisconsin from a Coop but that is probably a windchill misreported. A number of weather stations are reporting -40˚ rn in Northern WI and MN. So we'll see what the PNS shows once it's updated. (They'll all tell you that this is nothing compared to 1996.) Twin cities at -15˚, but were below -20˚ yesterday for the first time in 7 years.
