Wyoming Hits -26°F in Arctic Blast; 3 Feet of Snow in Michigan's Upper Peninsula

By: Dr. Jeff Masters, 3:30 PM GMT on November 12, 2014

A bitter cold blast of Arctic air more typical of late December is plunging south over the Midwest, and will immerse most of the eastern two-thirds of the country in December-like cold for much of the coming week. Casper, Wyoming bottomed out Wednesday morning at a numbing -26°F, their coldest November temperature since weather records began in 1937. Casper's previous November record cold temperature was -21°F, set on Nov. 23, 1985. Laramie, Wyoming hit -22°F Wednesday morning, a record low for the date, and Yellowstone hit -20°F. The storm brought very strong winds with it, with several mountaintop locations recording wind gusts in excess of 80 mph earlier this week: 81 mph at Pikes Peak, Colorado, and 84 mph at Snowbasin, Utah. According to the Wednesday morning NOAA Storm Summary, a whopping three feet of snow (36.1") fell at Ishpeming in Michigan's Upper Peninsula over the past three days, and numerous locations in Michigan received more than 20" of snow, including Marquette (20") and Negaunee (32.5".) Snow amounts in North Central Minnesota were as high as 16.5", and northern Wisconsin got a peak of 26" at Gile. The storm and associated intense cold is being triggered by an usually extreme jet stream pattern, featuring a sharp ridge of high pressure over Alaska and a deep trough of low pressure diving to the south over the Central United States. This extreme jet stream pattern is due, in part, to the influence of Super Typhoon Nuri, which caused a ripple effect on the jet stream after the typhoon became one of the most powerful extratropical storms ever recorded in the waters to the west of Alaska last Saturday.

A sharp kink in the jet stream (Figure 2) allowed cold air to spill southwards out of the Arctic over the Midwest U.S. Compensating warm air flowed northwards into the Arctic beneath a ridge of high pressure over Alaska.

Quoting 440. Naga5000:



It is possible it would be a complete failure, or maybe not. As we currently stand state run oil companies control 75% of global production. We are the exception here.



American exceptionalism? I say yes.
"you'll probably see Texas and Alaska (for starters) leave the Union."

me thinks that If it meant getting rid of Perry and Cruz (especially him) that wouldn't be such a bad thing! ;-}
Looks like this blog devolved into a political argument. Anyway, it's snowing a bit in STL.
GFS really pushing the cold air down into Florida next Wednesday.

33 degrees in Orlando.

(You quoted me)Yes. if you are talking Social Security retirement.

Incidental to this, I recently became aware that disabled persons of any age.... including those disabled with mental health issues... can be on Medicare now, rather than Medicaid. And we wonder about the rising costs of Medicare.

Of course there's lots of other reasons our "socialistic" Medicare costs are so high, and why health care insurance is so expensive - stuff that's inherent in our health care system. (Add by bf: I put a comma at the end of that sentence, not a period. Here is the rest of the sentence: and why health care insurance is so expensive - stuff that's inherent in our health care system.
(End of what I wrote that you responded to)


ricderr posted: our medicare costs are so high not because of socialism...if it was socialist in nature then the costs would be controlled at a fixed rate......
Please note my "socialistic" in quotes. This indicates a use of the word that is tongue in cheek. Pointing out others call it so. I do not see it as such.

So, ric, should it be socialistic? Partly it may be now, since Medicare is pretty much billed and paid at a fixed rate governed by diagnosis and what is known as "managed care" concepts. I'm guessing the business you are in is affected by managed care, so you probably know what that is.
...

Bye, wu. Hope everyone has a great day.

I also live the ACA, prior to it no one would sell me health insurance at any cost due to pre existing conditions. It is easy for anyone to go to healthcare.gov and look a policies that will refute all of your claims.


too bad you are that closed minded...we cannot change what is fact...we have an insurance agent that tried to find something for us in the ACA...it is there but wont cover us like our current policy...the only reason we have coverage is because of when we got it compared to when he was diagnosed...don't tell me the ACA has something for us that is comparable...there isn't...and you can ck if you want to about maternity coverage...call an insurance agent in SC...you must carry it by law even if you cannot have a baby...that 700+ page ACA and its nonworking website mean that we will get FUBARed

Winter Storm Bozeman has been named.
I think a good idea would be to name the winter storms after the more notable bloggers, for example the next storm should be CycloneOz, followed by Deepsearising and continuing right on through winter storms Sar and Tazmanian. (you could be the first storm next year!)
Also Al Roker has just completed hour 14 in his attempt to set a new world record by broadcasting weather for 34 hours straight. At this point he seems unstoppable and I wouldn't be surprised if he goes for 40 hours. The man is a meteorological animal !!!

Good morning Taz!!! Are you following Al Rokers "Rokerthon'? He just passed hour 13 in his attempt to set a new world record by broadcasting weather for 36 hours straight (and he's doing it without drinking coffee!). It is absolutely riveting and I don't plan on leaving the tv until he see's this through!


Meh on his attempt. He's in a cushy studio environment. I broadcasted during Hurricane Irene for over 72 hours straight until I passed out in the front seat of my car. After an hour...I broadcasted again for another 12 hours straight.

I would love to see a weather system named after me...but my first name is Brian...and it means "strong."

There will never be a Hurricane Brian. The elite namers of hurricanes don't have the cojones!
