That makes sense. 22z would be 6pm and it was still light out so that matches my memory. Doesn't get dark until closer to 7 in late September. Looks like it started around 5:40pm.

I wanna say late afternoon?

There's plenty of peer review research to read that will argue humans aren't responsible for the increase in CO2, but in reading them, you'll note that they don't hold up under scrutiny as time passes and other papers rebut them and they aren't able to counter those rebuttals. So they are fewer and fewer these days. I would suggest reading literature across all spectrums and not try and muck up the thread by insisting you know more than these papers.

They didn't attempt to quantify the non-climate factors though which was a bit frustrating in reading the study. I just finished reading it and they sort of just decide that VPD fits well enough that it is dominant. That might be true but it would have been nice to try and isolate it from the non-climate factors which they admitted is something they weren't doing in the paper...so we could see numerically how dominant it actually is.

It's actually not clear at all for "the current event" given that the autumn attribution is extremely weak to non-existent. It seems the trends are stronger for summer. From the most recent paper you linked: This is the problem with some of the attribution studies that are in a shorter time span. Esp starting in the middle 20th century.

I actually remember the snow on 9/30/92. I was outside playing and it started as a shower and quickly went to graupel and then some legit flakes mixed in at peak intensity. It was pretty awesome.

Gonna get a lot more too coming up in multiple shots. Great early season pattern out there.

That epic band in that storm

That's because there were two snow events...an October rarity. 10/15-16 and 10/18. 2011 also had two events. A little teaser on 10/27/11 two days before the big one.

Nice Fozz. You did March skiing last year. Best open secret in New England is March skiing. You'll see crowds in mid December with people skiing down man made icy death ribbons...but then find no lines with 8-10 feet of base and all glades open in March. Sometimes people are funny like that. But taking advantage is great. It's prob why ginxy usually does his Sunday River trip 3rd week of March. Most years I try to get out in March too...though last year I was shut out. Wife was pregnant and with another 3 year old just didn't make it out. But he's gonna be 4 this March and he's going on skis this winter.

Are you a really good skier? MRG is pretty gnarly so if you like that stuff, prob worth the pass at the sub-30 price. It's a hike and a half from RI though. Prob 4 hours. Youll prob be going to Mt Snow a lot on the drifter pass. Not nearly as far.

I'm not going to go down the political rabbit hole of discussing capitalism vs socialism in this forum but the nuclear energy part is spot on. It is hard to take any person or any group seriously that say they believe climate change is a dire emergency and also will not consider nuclear power.

Most politicians aren't really that serious about climate change anyway. Even the ones who claim they are. There are some exceptions of course. But we see something like the Paris accord being touted by politicians as this crucial thing when in reality it is non-binding and even if it wasn't, the commitments through the end of the accord in 2030 would do very little to change the longer term outcome of climate change...especially if one believes that we are closer to the "worst case" scenarios of higher climate sensitivity. The difference is something like a couple tenths of a degree Celsius or even less. If you are generous and make a bunch of assumptions like everyone continues to ramp up their cuts beyond 2030 like I've seen done in some analysis, then you can maybe add several more tenths. But that's a big assumption. It comes across as something for politicians to pat eachother on that back about to make them feel as if they are tackling the problem when they really aren't. This probably isn't the thread for such discussion, but a far more efficient way to attack the issue would be to invest most of the money into R&D for green energy.

I should update this in that the NSIDC minimum extent dropped a bit further to 4.09 million sq km....still outside my range but a bit closer than the 4.23 initial value I posted above. Doesn't change the analysis above in any material way. The area minimum hasn't been matched again and will remain at 2.87....we're now over 300k sq km above the 9/4 area min so that won't be caught again. We'll see if 4.09 million sq km is the final minimum extent....still a chance it could fall back below that from the current 4.17 million sq km value, but it's getting very late now to significant drops.

Time to verify this prediction based on the data at the end of June. Assuming we have reached the minimums for both area and extent on 9/4 (looking more and more likely), then both of these fell outside my range, albeit not by much. The final minimum area was 2.87 million sq km and the final minimum extent was 4.23 million sq km. These are both NSIDC numbers. The predictions were looking excellent through mid-August until we had an unprecedented slowdown in late August that has leaked into early September. So I ended up making predictions that were slightly too low compared to reality. I was correct in identifying the very strong chance of a top 3 finish (and also being skeptical of challenging the top spot), but I really needed to bump my middle numbers in the range up about 100-200k. Overall, I think this was a decent prediction compared to what we see on the Arctic Sea Ice outlook that gets published by NSIDC....but I am still disappointed I could not get it within my range. It might be that 200k error bars are just too small to consistently hit on predictions when it comes to sea ice. Using 400k error bars would have this method hit every year I've done it with the exception of 2016. But I will probably try to continue to use 200k error bars....and maybe see where the method can be improved.

I'll do it by type of event: Snowstorm: December 1992 with close to 3 feet of high water content snow....it would speak for itself back in the ORH hills regardless of when it occurred....but the fact it was the storm "that broke the snow drought" made it even more memorable. It was the first double digit snow event at ORH since January 1988. The longest stretch on record there. What a way to break the streak. Ice storm: December 2008. About an inch and a half of ice at 31F. Amazing event. Most people posting on here were on the forums for this one so they've seen all the pics and such even if they didn't directly experience it. Can't match January 1998 up in NNE but basically no ice storm can. Severe: The May 31, 1998 macroburst at ORH. Produced a 104mph wind gust at holy cross. Just shy of 100mph at ORH airport. I was legit scared it was a tornado when I heard the winds starting to whistle while under a tornado warning. Made it to basement as we heard a massive crack. 3 foot diameter tree broke next to us. Tropical: Chased Irene on the Cape with Phil and we got sustained around 60mph with gusts near hurricane force. Pretty good all things considered. Slim pickens in New England the past 2-3 decades. Bob in '91 had some pretty good flooding but not great winds back inland. Heat: Probably July 1995 only because of the dewpoints with it. It wasn't as intense as 2011 but it was more uncomfortable. Cold: January 2004 if we're going on combo of longevity and pure misery. Thin snow pack and brutal winds. If we're going on just shear peak magnitude it's Valentines Day 2016....absolutely brutal. Only lasted about 36 hours but it was epically intense. Froze our shower drain for over a day. January 1994 gets a mention of throw some wintry appeal deep snowpack into the equation....and the lowest daytime max of 1F. Recently tied this past January.

CAR going from +1C to -8C in one hour I impressive on the '76 cold front.

The daily area did start falling again....but it was only 18k. Down to 2.981 million sq km....the min so far was 2.877 on August 24th.

That's the 5-day mean, the daily area actually increased 20k to 2.999 million sq km. Not that the area matters much anymore for ranking purposes...this season will rank 3rd lowest for area behind 2012 and 2016.

There is no way the min would be that early.

I was looking at JAXA when I made the comments about extent. I agree NSIDC extent looks a bit less likely to finish 2nd but it wouldn't surprise me either. It only needs to have slightly above average losses...though the shape of the ice pack doesn't look as favorable for losses compared to years like 2016 when there was a lot more vulnerable ice left.

Area is very likely to finish in 3rd place given the path of 2016 from here on out. Extent is still looking like 2nd place is the most likely but the recent stall has made 3rd or 4th place more possible than it was a week ago.

Melt ponding is supposed to occur more readily on first year ice than multiyear according to the literature but let's say that is flawed analysis....if melt ponding was truly getting harder because first year ice is somehow getting so bad and other factors now contribute more to melting because of this, then we would expect the NSIDC area in late June to significantly over-predict the amount of ice left at the end of the season. We haven't really seen that in recent years....except 2016. But it didn't happen in 2017 or 2018. It doesn't look to happen in 2019 either unless something pretty crazy happens in the next couple weeks. The late June area data (which is a proxy for melt ponds) told us that we had a good chance for 2nd lowest but not a good chance for lower than 2012's record. There's nothing glaring that says that data missed some sort of smoking gun on additional melting.

The role of the cyclone in 2012 is overstated imho. The ice was in terrible shape before it hit. I'm not really convinced it added that much to the losses. Maybe a couple hundred thousand sqkm or something. 2012 already had the highest percentage of melt ponds by the end of June suggesting a new record was likely. It was significantly lower on SSMI/S area than other years including 2019...it's the main reason I didn't think we'd set a new record this year despite this being the most favorable melt year in a while. It just didn't quite stack up to 2012's early melt ponding.

The NSIDC data I'm using is from their satellite dataset. Specifcally the SSMI/S satellite. Jaxa and U Bremen use the AMSR2 satellite, which is highest resolution of the two. SSMI/S is useful though because it has a pretty homogeneous dataset going back to 1979. IMS uses both satellite and human augmentation of the data based on visual shots of the ice.
