Oops. Maybe I should have said “Global Cooling” there.
This Climate Change stuff sure is confusing.

Snow extent in the Northern Hemisphere at the end of November represents an important parameter for the early winter forecast. This year snow extent is running much higher than average and according to existing global estimates, it is now beyond the highest ever observed so far. Winter forecast, especially in its early phase and in Europe, might be strongly influenced by such a large snow extent, although many other factors need attention.
SNOW EXTENT IN NOVEMBER 2022..
Northern Hemisphere snow extent is currently indeed very high, now at about 41 million square kilometers..
...
Looking at the below Rutgers Daily Snow Extent map, it is clearly noticeable how Russia is completely covered in snow now. Snow is also seen overwhelming all of Canada, and Alaska, as well as a good portion of the Lower 48. This is an important parameter for the early winter forecast.
You could probably forecast a colder-than-normal winter based on Autumnal Northern Hemisphere snow cover extent alone. It’s the largest snow extent in decades. Having so much snow on the ground means any arctic outbreak is going to be a little bit colder.
...
In North America snow extent for the end of November is more south than normal, especially in the North West and North East sectors of the U.S: Small and scattered negative anomalies are less significant in the picture, mostly affecting central Mongolia, North East China, and the central U.S.
...
According to the Finnish Meteorological Institute, also the total snow mass for the Northern Hemisphere is tracking comfortably above the 1982-2012 average. This result is based on the current Northern Hemisphere snow-water equivalent relative to the long-term mean and variability.
...
Snow extent grew pretty fast in the last 30 days, as it should generally be in this period of course, but 2022 is setting a clearly very favorable season for snow on the ground. In the video below you can see how fast the snow extent increased in the last 4 weeks.
By the way, as a curiosity, the temperature is always colder on the ground in winter and at night in calm conditions, that is without or with the very weak wind. That’s because the Earth warms up and cools off much faster than the atmosphere does. More, colder air is denser, therefore the air near the ground is colder at night than the higher air. That’s why for instance your thermometer says +1 or +2 degrees Celsius, but you might see frost on the ground.
Extensive snow extent early in the season is an indicator of persistent cold as we head into winter proper, mainly due to albedo and emissivity feedback.
Albedo is defined as the fraction of light that is reflected by a body or surface. On average, the Earth reflects about 30 percent of the sun’s radiation, but when fresh snow covers the ground that value nearly triples and it is close to 1.0. In fact, snow has the greatest albedo on Earth, from less than 0.60 for wet and melting snow to greater than 0.85 for fresh snow.
The albedo of fresh snow could be as higher as 0.95, which means it reflects back to space 95 percent of the sun’s radiation, keeping the ground and air much cooler.
It represents an important parameter in climatology since recent albedo decreases in the Arctic have increased heat absorption at the surface leading to the so-called Arctic Amplification. Practically, Arctic lands and sea are warming faster than other environments on Earth due to the positive feedback induced by the darker surface of the land and sea in summer, where there is no snow or ice on the ground or sea ice melted.
I’ll stick with Joe Bastardi’s predictions at Weather Bell. I know many here are fans as well.
‘The Saturday Summary’ video is at the bottom of the page. Worthwhile viewing each week as we go into Winter.
Park City opened on November 16 with 433% of snowpack for this time of year.
Last time was 26 years ago.
Dont tell the crazies.
Farmers Almanac predicted a colder than normal Winter this year.
We have snow on the north facing hills from two weeks ago. More expected late this week. Local ski areas partially opened a week or so ago. 13 degrees the other day for overnight low. 🤔❄😲
Where’s Global Warming when you need it...
Paging “How dare you girl”...
Here at our ski area in Eastern Idaho we have already received 100 inches of snow. That’s 8 feet and more coming, it is not even winter yet. Temp’s have been below zero every morning for weeks. Our local liberal paper is advising us not to get our hopes up about the ski season though because of “global warming’ or something. This lib journalist’s are all depressed that reality is going against the established narrative. They can bite me.
“Follow the Tonga Volcano of Jan. 15, 2022 “

You are absolutely correct, and since it happened late in winter the effect is more prominent now. What I am surprised by, is the lack of discussion on the topic. We know that the Krakatoa explosion caused ‘the little ice age’ in 1815, I believe.
I better cut some more firewood.
To be fair, over 90% of that snow is concentrated around the Buffalo NY area.
(that’s humor, or my attempt at it, so no taking it seriously.)
But they promised global warming. Can I sue Al Gore because this is going to delay my beachfront tropical resort in Buffalo, NY? Even considering moving the plans to further south to Cleveland.
A colder planet is caused by Global Warming, just ax science.
“”Controlling climate is impossible””
Controlling how people feeeeel about the climate is another matter. When presented with facts that do not coincide with a liberal’s feelings, liberals resort to the old tried, and not, so true, racism charge. You see, in the summer ‘people of color’ are not smart enough, according to liberal wackos, to seek out shade, and perhaps air conditioning. So, instead of advocating air conditioning for everyone, wackos want more people without air conditioning. (If they were ever to significantly succeed in diminishing the use of air conditioning, they would probably attack sitting and standing in the shade, since not everyone, and especially ‘people of color’ have access to shade).
This Climate Change stuff sure is confusing.
Minorities are also, apparently, too stupid to get ID to vote yet all have iPhones…
Snow keeps the ground and air much cooler. Who knew?
It is my firm belief that the climate is mostly self-regulated. Something causes it to get warm.. something changes to cool it off again.
Only something like the sun changing, a comet, or massive volcanic explosion can have any big impact.
Uh uh, nope, un-possible, I’ve been told the erf has a feva.
“snow extent” ?
Never heard of it, but the author sure likes the term.

We have a winter storm warning for the Cascades and the foot hills east of Seattle.
All the mountain passes expect heavy snow or possible closures.
Curiously, Seattle has been in a moderate drought since July.
Our rain fall since October 01 (start of rainy season) is about 35% below normal.
This is our third La Nina winter in a row, which is quite unusual.
La Nina pushes colder than normal ocean water towards Washington state.
Colder ocean water usually means less precipitation, including less snow.
