Massive Arctic cold wave descends into southern USA

Polar vortex outbreak creates 90 degree difference from one end of Texas to the other

Look at the cold plunging from the latest polar vortex incursion:

Notice the difference between Houston and Dallas, or New Orleans and Wichita now take a look at this map. WeatherBell’s Ryan Maue reports that the coldest state in Lower 48 was Iowa, with an average of -1.0°F

Look at the gradient across the front in Texas, note how sharp it is; a 90 degree difference from the southern tip of Texas to the Texas panhandle.

Reminds me of when I drove from Utah down to Arizona to buy a boat. My daughter was sun-bathing in the 80 degree weather in Arizona in the afternoon. It was 10 degrees when we got home that night.

“I am guessing most folks on this blog are fans of “big weather” & this certainly qualifies ! Fun & exciting stuff to follow ”
You’re right. I’ve always been a fan of big weather. Dad had to drag me into the house every time a thunder storm blew up as I wanted to see every lightning strike and hear the kind of thunder it would generate. Funnel clouds! Thunder snow in January! Always loved the way big weather could humble us all.
But now it sadly seems all these wonderful displays of the immense power and complexity in the atmosphere can’t simply be watched in wonder like they were when I was young, but must always be seen through the disgusting supposedly explanatory prism of “climate change” or “disruption” or whatever. Goodnight everyone.

By the way, it’s 16 below F here in Saskatchewan and heading for -20.

If you’ll pardon a sneaky topic drift, it appears that this massive cold wave may have been dwarfed in scope as compared to the cold shoulder afforded to CAGW at the Oscars. Unless I missed it (I did have a few lapses in viewing), not a word from the notoriously green and in-your-face glitterati to be heard about CAGW ! Not a good sign at all for the warm-mongers.

The anomaly in the the zone of the ozone began in September. Just running solar activity.

So where do all this air come from to support such a movement of cold dense air across thousands of miles?
—————————————————————————————–
There were several years of a strong El Nino at that time. Could that have caused large scale air movements to push north?
Lil Fella…compared to last year the sst anomalies patterns in different places around Australia are significantly different from last year, to the cool side. The hot cycle could well be over for Australia.

Is it worse than we thought? The polar bears in Canada, where I live, are knocking on our doors wanting to get in from the cold.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Useless fact of the day: Local bylaw in Churchill Manitoba requires that vehicle doors remain unlocked so that they can be used as a means of protection by pedestrians in the event of a polar bear encounter.

Dear Winter,
It’s been fun, but our relationship has been growing cold lately. I hope you don’t take this too hard, but I want to break up with you and see other seasons.
Love always,
Too Blue Lou

Obama do not have time or patient to listen to denier reality or denier temperature facts. The debate is over!

Again, thank you WUWT, very happy not to be in Canada this winter. Does anyone think this is the start of the next glaciation or is this our 30 year cool down? I guess it will take a few more winters to tell. If it is the start of the next glaciation, I am not far enough south.

Well this winter makes me glad I told my daughter she couldn’t go to University of Michigan. Very fine snow started at 3 a.m. here on the south shore of Long Island.

“sudden appearance of the Northern lights was considered a bad omen?”
yes it was a sign storms were coming. which correlates with the sun as the driver of weather.
as the magnetic shield is weakening at a fast rate some say this will be great because u can see the lightrs very far south but what they seem to miss is there will be consequences too.
if the magnetic shield is weakening due to magnetic reversal it can fall by 90% . one good x flare pointing at the earth then would blow out the power on earth for months maybe years never mind having wild storms too. Cancers would rise. Latest evidence i seen suggested that when the pole does start to move it can move 6 deg a day and not the slow movement over 100s of years that some say now.
if the co2ers really want to munch scream magnetic shield weakening is a better one lol

All that money wasted looking for the ‘God particle’ (Higg’s boson) when CO2 can have so many effects on the weather in so many different ways, and all at the same time. All hail CO2.

Coldest winter ever (evah, evah evah, in living memory, etc. etc.) !!!
Global warming is not working out quite as planned, SO :..
Blame Canada!

I was actually worried about an invasion after we won four golds in hockey and curling…
Sorry…. 🙂

Around the globe:
– 7 stations have broken their daily high record
– 95 stations have broken their daily low record
at least one has broken its all-time lowest recorded temperature. Manistee Michigan which is on Lake Michigan and at -22F, is not much of an all-time low but proximity to the Lake probably impacts that.

Being an avid Weather Channel viewer when on vacation in Florida (during the UK winter) – enjoying 75-80 degrees – I’ve always thought: ‘Why would ANYONE live in Great Falls…?’

Tom in Florida “Meanwhile, just another day in paradise.”
Just a quick tip from an old man. Once you find a place that you really like, never talk well of it. Once word gets around about how nice it is, you will be deluged by people moving there and it will change very quickly — and not for the better. Only praise where you live when you are talking with your neighbors or with your nearest and dearest friends.
Try this when speaking with any out-of-towners: “Yeah, I guess where I live is OK… at least if you like mosquitoes and cockroaches. Of course they are worse after a hurricane, and believe me, I’ve seen some doozies! We still have water marks on the sheet rock in the living room. But usually, they get the water and sewage systems back up and running pretty quickly after a big storm. It hardly ever takes more than a couple of weeks.”
At first it will be difficult saying bad things about where you live. Practice until you are good at it.

Yeah, work is cancelled today in little Rock because there is a sheet of ice on the ground and its 18 degrees. This has never happened in march. (Apparently of it doesnt get over 30 it will be an all time cold record for today and its predicted to get to 25 or so). Insanity!

We’ll be flirting with -9 F tonight in western New Hampshire. Not quite a record low, but nearly…

“Its called weather …it comes… it goes”
You are correct. However, the delusional CAGW scientists/advocates of today would interpret ANY weather-related **warm spell** as a sure sign of global warming. This is why WUWT does these posts on cold weather events – to counter the CAGW scare-spin bilge we see in the modern media.

“Excuse me being ignorant are you C or F on the map?”
when puerto vallarta hits 81 centigrade, I think we are all in trouble….
dont you?
When Puerto Vallarta hits 81 C I’ll believe in Global Warming.
