It actually snowed a few flakes here earlier this morning. Will be 25 deg F tomorrow morning. Wintry mix earlier but it's cleared off now. Wind be howling still tho.
There are weather and climate "whiz kids" who are saying that this IS global warming.

The jet stream, which flows west to east in the upper atmosphere over the Northern Hemisphere, is driven by temperature differences between the cooler polar region to the north and warmer air masses to the south.
As this river of air circles the planet, it can undulate and create larger-than-normal peaks and troughs that impact weather systems. When the jet stream dips south and creates a trough, this allows cold, polar air to funnel southward. Conversely, when the jet stream swells into a peak, warmer air rushes in to fill that void and drier conditions typically prevail.
“What we have now is a wavy pattern where the peak of the wave is over the western U.S. and the downward portion of the wave is coming over the eastern U.S.,” Chenard said.
The ridge over the western part of the country is responsible for the dry conditions and above-average temperatures that have fueled devastating fires in California in recent weeks, said Jeff Masters, co-founder and director of meteorology for Weather Underground, a commercial weather service headquartered in San Francisco.
“The two are correlated — where you get one extreme, it gets balanced by the opposite extreme,” Masters said.
That is text that I copied from a new NBC News report.

Though some seasonal variation is natural with the jet stream, there are some indications that climate change is affecting the waviness of these air currents.
New metrics and evidence are presented that support a linkage between rapid Arctic warming, relative to Northern hemisphere mid-latitudes, and more frequent high-amplitude (wavy) jet-stream configurations that favor persistent weather patterns. We find robust relationships among seasonal and regional patterns of weaker poleward thickness gradients, weaker zonal upper-level winds, and a more meridional flow direction. These results suggest that as the Arctic continues to warm faster than elsewhere in response to rising greenhouse-gas concentrations, the frequency of extreme weather events caused by persistent jet-stream patterns will increase.

Is it a Polar Vortex? It's related to the Polar Vortex phenomenon, but I would advise caution about connecting "Polar Vortex" terminology with this latest gi-normous freeze out that has just settled over such a vast region of Canada and the United States.
I don't know if the fully credentialed meteorology and climate community is thinking about this (to invoke the once famous Coca Cola saga) as "Polar Vortex Classic" or "New Polar Vortex."

for 100+ yrs, they (and more recently, we ) used to just call this a "blue norther/Texas norther". Now, it's gotta have a special name to somehow tie into the new fangled 'climate change/global warming/ (whatever the next darling term of the left is)
"wavy jet stream" yeah..rightttt.....nothing new, nor unusual except for the # of gullible people who believe it is.
quote
Perhaps the single most extreme blue norther in Texas history was that associated with the famous arctic outbreak of February 1899, the greatest such in the annals of U.S. weather history. In his classic weather book Texas Weather author George W. Bomar states that temperatures on the afternoon of February 3, 1899 had almost reached 100° at sites along the Rio Grande (specifically 99° at Fort Ringgold and 97° at Fort McIntosh—now known as Laredo). The cold front swept through Texas on February 8-9 and by February 12th the dome of high pressure was centered over the state with Abilene measuring a barometric pressure reading of 31.06”. Temperatures had fallen below zero F° across the northern two-thirds of the state with a minimum of -23°F at Tulia on February 12th. Fort Ringgold registered 7°F and McIntosh (Laredo) 5°F also on the 12th, all-time record low temperatures for the sites.
As is often the case with blue northers little precipitation accompanied the passage of the front.
Another infamous blue norther was that of November 11, 1911 although it was more notable in Oklahoma, Missouri, and points north than in Texas. More about this can be found here< on the NWS-Norman, Oklahoma web site as well as here on the NWS-Kansas City web site.
Yep, just normal weather. Just like mj is suggesting. And the climate alarmists, like rinse believe that somehow this is all due to man made climate change. Heck they can't even use the same terms decade to decade. A long time ago it was the new Ice Age then Global Warming, and now Climate Change. All just Chicken Little talk.
Mankind doesn't even have enough climate data to make any kind of prediction or comparison. Especially here in the US.
There are a few chicken little's here I've been having some fun with. They scream that's it's never happened in November and I ask what month did the Edmund Fitzgerald go down during a Great lakes storm.

"Whiz Kids" being code speak for for the Global Warming alarmists ? NBC News, CNN, ABC, CBS, Dumbocratic party ? Honest question. Who are the "whiz kids" ?
Never mind. I answered my own question. Your capricious arrangement of quotes does allude to Denise Chow of NBC News. Who is Denise Chow ? (A useful idiot supporting a desired narrative.)
Denise Chow, on Twitter, 16 hours ago :

She admits to trying to make Global Warming a thing. Let's see how she did. Keep in mind that she is college edjumacated.

Me, a high school drop out, wonders why the wind is not blowing north all around the globe. She says the warmer air from the south is going north. All around the globe, the average air temperature is the same at the equator, as with the poles. I would be looking at the variations in high and low pressure areas. My dumb azz is smart enough to recognize the low pressure areas of a hurricane affect wind direction, and that wind direction changes from day to day at anytime of the year.
Let me go on.

Some indications ? There must be. She didn't elaborate, .
Denise Chow, raised in San Francisco (surprise), relies on Jeff Masters, co-founder and director of meteorology for Weather Underground, a commercial weather service headquartered in San Francisco.
Weather Underground ? Where have I heard that name before ? I remember now. Weather Underground was a radical left-wing band of thugs led by Bill Ayers (remember him ?). Is there weather underground ? Why would someone found a meteorology service named Weather Underground ? Perhaps because the new DA of San Francisco is the son of parents who were members of the radical left-wing Weather Underground. Chesa Boudin grew up with his parents incarcerated for their roles in an armed robbery that left three men dead.
Speaking of new DA of San Francisco, Chesa Boudin, he has vowed not to prosecute crimes of quality of life. Such as openly urinating and zhitting in open on public sidewalks and offering or soliciting sex. Can I bend my wife over on the rear of my Fiero and boink her in public ?
Let me go on.

Originally posted by cliffw: Some indications? There must be. She [Denise Chow's report for NBC News] didn't elaborate.
The report from Denise Chow does elaborate, by referencing the letter that was published in 2015, in Environmental Research Letters, under the title of "Evidence for a wavier jet stream in response to rapid Arctic warming."
I provide(d) the abstract or summary that is part of the publication of that letter; to wit:
quote

These results suggest that as the Arctic continues to warm faster than elsewhere in response to rising greenhouse-gas concentrations, the frequency of extreme weather events caused by persistent jet-stream patterns will increase.
I cannot speak in any direct way as to how convincingly (or not) the body of that letter supports the abstract or summary of it. It's a long letter, with a sequenced set of visualizations of numeric data or data plots. That is why it was published in Environmental Research Letters, instead of in Cigar Aficionado.

Why wouldn't someone... ?
I think it's clever. I think it's a more or less obvious way of putting a spotlight on the Empiricism and Practicality that are the hallmarks of reliable weather forecasting, by reminding people of the polar (pun intended) opposite. That being the Chaos, Anarchy, and Psychopathology that are the literal legacy of the original "Weather Underground."
I personally am glad that Jeff Masters did not opt for "Jeff Master's Reliable Meteorology Services", instead of "Weather Underground." Because, otherwise, I wouldn't be having this moment of recreation, of going online here and messaging about it.

Yeah, now that I think about it again, what cliffw was actually referring to in his message was a group or network that included some people who were both radical enough and criminal enough to get involved in the committing of arson and bombings. They first became known as the "Weathermen." But that kind of morphed into "Weather Underground" as another name for it.

I have also been thinking--all along here, as soon as I engaged with cliffw's message--"Wasn't the 'Weather-centric' terminology used as the name for some rock band or pop music group?"
Weathermen? Or Weather Underground?
But I don't think that I am mistaken about connecting it with a network of politically motivated activists, some of whom committed arson and bombing crimes of a particular character. "Let's burn down or blow up the ROTC building on campus. Let's do it on a weekend, after sunset, to make a 'statement' without killing or maiming too many other people. I mean, just two or three human casualties we can live with."
Isn't that kind of the way this other "Weathermen" phenomena played out?
Weather I'm right, or weather I'm wrong ...

A '70s Fusion group, Weather Report:
Wayne Shorter and Jaco Pastorius

That "rings a bell." I remember "Weather Report" being talked about as the name of a band. Now that the memory has been refreshed. But only to that small extent. I can't say that I remember anything about the band itself. I look it up now and see "Wayne Shorter" and that's a familiar name to me, filed under "Jazz, Instrumentalist, saxophone." Something I might have been able to "cough up" before this conversation, had I been prompted to do so.
Let me go out on a limb and conjecture that "Weather Underground" is how the more enthusiastic fans and followers of Weather Report came to be known? That seems about right. I think I remember hearing and possibly reading such references.
Maybe, later today, I will add something to my previous message that connects the Big Freeze that's been going on, across such a gi-normous swathe of the Eastern U.S. and Canada, with Jet Stream boundary instability or "waviness," and how that is not a contradiction of Global Warming, but lines up with Global Warming in a positive way, in terms of explanatory coherence.
Now for a word from the makers of WeatherTech floor mats and cargo bed liners...

I imagine that the misguided moniker of the meteorological mecca "wunderground.com" was meant to make mirth of the malicious mob of miscreants. However, I suspect that you have their etymological timeline inverted.
I have never heard of any special name for fans of Weather Report, but you might remember their song "Birdland".
At any rate, I blame it all on Lena Horne

Worldwide climate is doing what its done for billions of years. It changes from day to day. Our local weathermen cant even predict accurately what its going to do in hours. Ive heard the local news talking about the whole area being in thunderstorms from their studio 5 miles away from me...while im in the backyard...in the sun, washing my cars. That particular day, it never did rain a drop where I was. I remember Gore starting this bs warning that the cities along all the coast lines...New York, Miami, DC, London...etc, would all be flooded in 10 years. That was 20 years ago, so even giving him a time break never happened. The hotels on the coasts all still are there along with their beaches. The beach behind the island house, in the Caribbean, is exactly where it was 150 years ago. Those bs artists now have affected the youngest generation, making them activists to save the Earth. I guess if you say something enough, some people will believe it. Scientists have said Mars was once similar to Earth and it was devastated by planet warming. They have yet to find a power plant or the millions of Martian SUVs that caused that. Yes the Earth is going to be just like Mars at some point billions more years in the future because thats the way nature works. Man has very little to do with it. When the dinosaurs walked the whole planet was very warm...plant eating dinos and plants have been found everywhere including the arctic. There were no men then. Did the dinos somehow cause that climate ? Dont think so...it was plain ole mother nature. Then explain the ice age...did men all over the planet leave their refrigerators open ? Its all natural...plain and simple. Its all morons with nothing else to do for the day except think up bs. I think there should be a 'Wake Up' Earth day where everyone turns on everything they own from cars to light bulbs.
Worldwide climate is doing what its done for billions of years. It changes from day to day. Our local weathermen cant even predict accurately what its going to do in hours.
Agreed. And the climate activists like making up new terms. There is no such thing as a Polar Vortex. The first time I remember hearing that was in the movie The Day After Tomorrow. Now, weathermen use it regularly.
That movie that tried to explain to the unwashed masses like us how "global warming" can make the earth COLDER. LOL (of course that movie "blamed" it on changes to the Gulf Stream as well as CO2 in the atmosphere) People "didn't get it" - colder winters while the earth is "warming" is illogical. So they renamed it "Climate Change".
So now any weather phenomena could be painted as "due to Climate Change" (as long as it's "bad" weather) Nobody says "this has been the best growing season we've had, with bumper crop harvests "due to climate change".
