TWC   https://weather.com/forecast/national/news/2020-10-14-winter-2020-2021-temperature-outlook-united-states They kinda switched FEB

TWC is an IBM company and IBM was loudly advertising their powerful AI based forecasting prowess.

So this forecast is perhaps a reality check, there is still lots of room for improvement in this space.

Last threat of the season

 

A bold assertion indeed. Not a projection that I can put much stock in.

Given how erratic this winter has been, we'll probably wind up with a blizzard in May.

We cannot eliminate the possibility that we've seen the winter max for 2021.

The updated NSIDC trend lines support your supposition. Also the Arctic is considerably warmer than usual this year.. https://cryospherecomputing.tk/

I usually just go to NSIDC directly. https://nsidc.org/arcticseaicenews/charctic-interactive-sea-ice-graph/

I did see that glitch on that site earlier today. I was assuming the glitch was isolated to that site. The data on the NSIDC site looks good.

The data on that link also stop at Feb 19th and the scan map shows that one sector was unscanned, which was the cause of the sudden downturn.

Maybe a data processing issue with the satellite or the ground station?

We've seen a pretty substantial decline in the NSIDC sea ice extent the last few days.

The last time the winter max occurred in February was 2015. So there is recent precedent.

 

No expert, but the data at :  https://cryospherecomputing.tk/NRT2.html  show some sort of glitch since Feb 19th. Is there a better source?

Separately, I do agree that the recent ice trends have been suggestive of an early peak, but we do need a better confirm.

this provides it now! Freaking awesome. Just missing music - but for a lot of us, a nice addition to our forecasts but with a giant swath of nostalgia

Thank you for this helpful link.

I'm obviously a dinosaur, but I thought it a mistake to ditch the old style weather maps with the fronts indicated.

I don't find the maps with colored blobs of hi and lo pressure as informative.

Agree entirely, but this is just stupid, not politics.

A f***g nuclear plant going off stream because the cooling water pumps were frozen??? Just brain dead greed imho.

ERCOT just said that Texas’s power grid was a mere MOMENTS AWAY FROM CATASTROPHIC FAILURE:

 

 

 

Sadly it is only after such catastrophes that we learn to set serious standards.

Shipping is safer because of the Titanic, buildings are safer because of the Triangle Shirt Waist fire, Texas had lots of warning that cold spells could be a problem,  but no one hit the mule over the head with a 2x4 to help it see reason. 

Imho this is just another lesson that will soon be forgotten.

I only got another 1.2" of snow from overnight, so my total is 4.6" over these two events. I am considering myself very fortunate, as my power hasn't gone out at any point over these past few days. I'm not sure what's sparing me, as friends living only a mile away have been having their power going on and off.

Afaik, the grid managers are prioritizing locations with hospitals and similar sensitive facilities, at the expense of residential and industrial sectors.

Not sure how easily that is actually implemented though...

I remember seeing images from the north with snow looking like mountain ranges with cars driving in the "valleys"

I wonder what the highest annual average snowfall total is from a location at sea level?

 

Well, I've only been there in winter along the eastern coast, so can attest robust deep snow cover. But don't have any idea of seasonal averages.

do they get coastal storms more intense than ours?  I wonder why Tokyo doesn't get more snow lol

 

Hokkaido is considerably (about 500 miles) further north than is Tokyo, so it gets snow where Tokyo gets rain.

The liquid equivalents may even be in the same ballpark.

Hope she heals fast.  Ice is so damn dangerous.  Give me a rainstorm any day over a ZR storm. 

Two storms?  Another one next week? 

Does no one make rubber shoes with some sort of spiked sole?

They don't need to be huge spikes, just enough to give some grip on slick surfaces.

Just so you all know, 90% of our new posters are socks that sign up with untraceable IPs.  They are impossible to ban bc they just sign right back up with a new IP.   I feel like its only fair you all know this.  

Is it feasible to show the first sign in date for the posters?

That would perhaps allow us to filter the socks.

Whatever happened to the record cold NYC was supposed to experience this weekend?

Very wet snow falling in Manhattan UES since about 9.30 AM, mostly melting on contact.

Actual accumulation is modest, perhaps an inch as of 1PM.

Would guess it might be a more substantial event further north.

Karma for the Uber rich? As always ......

The super premium super tall apartments are mostly empty, owned by absent individuals to serve as a pied a terre on visits and as a safe stash of funds.

Not so many actually live there, so NYC gets eyesores that don't even give much back economically to the community. 

Now that this is in the books, did JB's expectation of 40"+ in the Poconos verify?

I've always respected his meteorological chops and he did get it right that this would be a big one, but he does get very enthusiastic when in the chase.

Yeah, forgot. The Conservancy Conservators were taking one shot per inch I guess.

Have to say, the details of how the Central Park site is run are murky, so I've low confidence that the numbers produced are truly representative.

The site is split afaik between the Castle, a high point in the Park and the remaining sensor array, surrounded by shrubbery and perhaps 30 feet lower.

Snow fall measurements are manual iirc, so not automated and consequently less uniform.

That is quite a lot.

It says that since 1960, the ocean surface layer down to 2000 meters has absorbed 3.6x10**23 joules, enough to warm it (about 7x10**8 km**3) by about a tenth of a degree Centigrade.

The ray of light is that the paper suggests that this is pretty much in line with the current estimates of how much extra solar input is trapped by increased greenhouse effects, so the increase should stay fairly stable.

Another non event hyped by the NYT, no less. Are they getting bored as well?

The snow, such as it was, barely whitened the detritus in Central Park, paths a little damp at most.

ps the "generational lead time" stuff happened in the 80s, it's quite apparent it's happening much more quickly now.

Is there any actual evidence of that?  We do have a materially warmer than usual Arctic, some beyond historical experience.

But it is difficult for me to see why there would be a step change in oceanic buffering when the increase in ocean temperature to date is at the limits of the measurements.
