USA record lows outpace record highs 19 to 1 this week

539 new snowfall records were also set.

Since we are often treated to lists of record high temperatures when heat waves occur and they are improperly linked to global warming (like in Russia’s heat wave this summer), I thought it only fair that I show the number of record cold and snow records around the USA for the past week that aren’t linked to global warming.

Of course it wouldn’t be fair to show just the lows temperatures and snow, so here are the high temperature records for the USA in the past week.

And here’s just the lows:

The summary of new records of interest for the past week in the USA :

Snowfall: 539
High Temperatures: 18
Low Temperatures: 336
Lowest Max Temperatures: 278

Lows outnumbered highs by a factor of 19 (336/18=18.6 ~19). That’s quite the cold snap.*

The coldest?

Deadhorse, Alaska,  on Sunday, 26 Dec 2010 at -40°F beating -38°F set in 1984

*Note: some people clicking on the interactive map will see different numbers, since that map will record new highs and lows as this post ages. The headline was originally based on 16 highs during the week (see the highs map for a ratio of 21 to 1) then by the time the post editing was completed and the post made, the number of highs was up to 18, giving an 18.6 to 1 (~19 to 1 in the title) ratio. Later in the day the number of record highs in the one week period increased as new weather occurred (on Dec 31) and reports came in. The numbers were accurate at the time the post started. Weather records, like weather itself are dynamic with the forward moving one week period the interactive map generator uses, so please don’t assume error if you click on the interactive map and the numbers don’t match now, or in the future. – Anthony

No wonder the horse died.

All this proves is that carbon taxes and the threat of cap and trade were enough to make the weather sit up , take notice then back off. Next we have to introduce a snow tax, and eventually we will tax the weather back to the ideal ‘normal’ state.
The weather will just have to learn the hard way, not to mess with us.

Meyer

It’s worth reminding the alarmists of the difference between weather and climate when they use record weather events as anecdotal evidence of climate change.

The Kid From Bristol

Other cities figured there’s no use beating a Deadhorse.
Badda boom!

Grumbler

Using eyeball Mark 1 method, how come the station just south of Houston [Corpus Christi?] has a record high and a record low in the same week?

The Warmists will still be complaining about CO2 when the mile thick ice sheets start rolling.

Renaud

Good to read this sort of balancing data, however I have to say that 336/18 is 18.67 and not 21, not that it changes a lot but just to have your record right.
It will be great if it was possible to do it at a global level.

Terry

Very timely post Anthony, but I thought that the latest model results show that these record lows are not only “consistent with” but also the “result” of global warming.
Thank goodness for the models putting us right, we might otherwise get the silly idea that minus 40F is actually very chilly.

David

I wonder how many of the record highs, if any, were used in GISS and extended up to 1100 K?

Robuk

USA record lows outpace record highs 21 to 1 this week,
Do you mean the UHI contaminated Hansonised highs.

TFN Johnson

Why no mention that Arctic sea ice cover was clearly the lowest ever recorded thru December?

tarpon

Last nights local weather said that this December will be the coldest on record for Florida … Unless today’s temperature breaks the new hi hi for the day of 323 degrees. The last part I made up, so don’t use it as a climate prediction … LOL
It has been cold in south Florida, our temperatures are struggling to get back to normal. Supposed to be achieved ‘normal’ yesterday, but those dang clouds kept us cold again.

David L

Record low, record high, what’s it matter; it’s a record and that means A) we evil humans are responsible and 2) more research dollars are needed and needed fast! /sarc

Claude Harvey

The computer models show this recent cold effect is merely Mother Nature’s thermometer squatting down on its Global Warming haunches as it prepares to leap into the stratosphere. Just as we changed “Global Warming” to “Global Climate Disruption”, we’ll change “tipping points” to “squatting points” and the Mauder Minimum will morph into “The Mauder Squat”.

John Day

Anthony, there are more thermometers in the Southeast than the West. So is it fair to base a claim on the number of records broken? Also, the Western thermometers were spread over a wider region than the SouthEast. (Just playing Devil’s Advocate here)

Peter

Just be thankful it’s only minus 40F and not minus 40C 😉

Anonymous Howard

Same statistic for week ending Dec. 25:
Record highs outnumbered record lows by a factor of 91 (272/3=91)
Both statistics are equally meaningful (and therefore equally meaningless).

BFL

And corrected for UHI, who knows how bad the lows REALLY were.

> I wonder how many of the record highs, if any, were used in GISS and extended up to 1100 K?
Probably very few. I’ve looked at some of the New Hampshire records in the past and came away fairly confused as to just what sites those are and what quality control is in place, and no idea of the length of the record.
Not that USHCN sites are any better! The best thing for these plots is confirmation that it was hot/cold last week. I generally ignore the record rain/snow plots, too many low hanging fruit to pick there.

I’m not sure if they included the Baltic Sea in the extent. It is where it usually is Jan-Feb:

Since we are ALSO often treated to lists of record LOW temperatures when COLD waves occur and they are improperly linked to global warming SKEPTICISM, what does total look like for some more significant period of time, like the past 12 month? In the last year how many record highs and lows have been set?

BillD

In the US and Canada for many months, in fact the year overall, the ratio of record highs to lows was over 2:1. It’s not surprising to have a nationwide cold snap at some point.

BillD

Recently, the upper Hudson Bay has been 18 oC above the long term average. Perhaps when the parts of the arctic with open ice finally freeze, we will get warmer temperatures down below.

PJB

The only things that are certain are death, taxes and climate change and I’m not so sure about death…

Sam Glasser

Dear Peter:
There is a big difference between +40 F and +40 C, but -40 F = -40 C.
Just be thankful that “global warming” now causes global cooling. Happy New Year, and do enjoy higher costs for energy in this coming year. Sam in CA

“USA record lows outpace record highs 21 to 1 this week”
So, essentially, one can infer that due to recent cold snap, and therefore the extra need for heat rather than light, the average greenie hippie home grower has not been able to harvest in time for the holidays. Which subsequently could strongly suggest that the lack of a surplus of weed is strongly linked to the lack of record highs.

Why no mention of a whole bunch of stuff off-topic from US record low temps? If you are interested in sea ice, go to the sea ice page.

Gary Pearse, You noticed the winkey at the end of my post. It’s amazing the number of people I’ve caught out with that.

Pamela Gray

TSA Johnson, not to point out the obvious, but I believe the title said “USA”. Unless I’m mistaken, the Arctic Circle doesn’t quite extend that far South, though my backdoor thermometer here in Wallowa County begs to differ.

“Eric Worrall says:

Do you mean like the Iraq news man who denied the Americans were in Iraq when they were almost in front of him?

Pamela Gray

For educational purposes only, I point TSA Johnson to a study on the affects of winter season Arctic Oscillations that turn negative. What this means is that vortex circulations (which form concentric circles around the pole, each with varying degrees of pressure and height above sea level), especially the high pressure one, moves poleward, while a less tight/lower pressure loosy goosy vortex circulation moves more South. When it is positive, the low loosy goosy one is at the pole and the high pressure barrier-like one is a bit further South.
When the AO is in its negative mode, this is like exchanging a pretty formidable solid oak barrier floor in our Arctic Attic for cheesecloth. All kinds of things leak out from around the perimeter, including ice and wind, along with frigid temperatures.
So what are the expected signs? Three things. 1. Frigid temperatures invading our nice Temperate climates, 2. Lotsa snow further South than would be the case otherwise, and 3. The Arctic core should freeze solid and thick, but the perimeter should be less than expected.
So what do we find? Three things. 1. The deep South drinking hot sweet tea instead of cold sweet tea, 2. Snow up to our hoo haas, and 3. The Arctic frozen sold where land prevents ice moving South and loosy goosy ice elsewhere along the perimeter, as in the Okhotsk and Bering Sea, Hudson Bay, and the Baffin/Newfoundland Sea.
I could add a fourth. We get moose in Oregon.
Case closed.
Now back to USA records.

Q1 2010 in west central Florida averaged 6 degrees F below “normal”. I’m not sure how normal is defined, at a guess the average for the last 20 years. Dec. 2010 in west central Florida has averaged 11 degrees F below normal. Today 12/31 is only the second day at or above normal for the month.

Pamela Gray

TSA Johnson, sorry for the grammatical and spelling errors in my educational post to you. Too early in the morning for class I suppose.

Peter Miller

You people are terrible – it’s time to think of the polar bears!
No one cares about these poor creatures, so get your wallets out now.
As for me, this emotional, unscientific and money grabbing crap makes me want to throw up.

Now do a 1200Km grid average and try and find anything meaningful in it. Then justify why the Arctic has shown warming in the 20th century.

Probably the guys at the Firehall decided to do some BBQ after the big freeze and all that lovely brisket cooking warmed up the thermometer located beside the BBQ pit.

so here are the high temperature records for the USA in the past week.
=====================================================
Some of those record highs are not really record highs,
they just tie an old record from up to 40 years ago

DJ Meredith

I hope someone is archiving this data, since it’s likely it’ll be “adjusted” to help 2010 be the warmest year ever.
It’s 6deg F here in Reno this morning….

Jimbo

I thought it only fair that I show the number of record cold and snow records around the USA for the past week that aren’t linked to global warming.

Sorry Anthony both record hot and cold is caused by global warming. They have to have it both ways. ;>)

Absolutely right, Pamela, but Iwould take the logic a step further as follows from a post I made elsewhere:
Always remember that more meridional jets during a cooling phase will encourage more warm air into and cold air out of the polar regions so during cooling spells the polar regions and high latitude regions immediately adjacent to them will always be warmer at the surface than during warming spells.
If one looks at the standard descriptions of the characteristics of the polar vortices that must be so. Poleward jets run faster round the poles to isolate the polar vortex which gets colder yet poleward jets occur when the globe is warming. The polar vortex is less cold when the globe is cooling.

My idiocy has led to some learnin! The Arctic Region is different than the Arctic Circle. Significant parts of Alaska may lie within the Circle but it apparently has less land within the Arctic Region.

There is not a day goes by that I don’t learn something new here or get a mistaken idea smashed to smithereens upon the rocks of facts and figures.

Again in Texas, we see record highs and lows next to each other, This is unlikely and someone should review these stations for accuracy. Likewise in Oregon we have 2 highs literally surrounded by snowfall, just about at Grants Pass. Possible, but unlikely.

Why no mention that Arctic sea ice cover was clearly the lowest ever recorded thru December?

Also why no mention of Arctic ice concentration?
By the way the 2006 January extent was the lowest on the record but in September it was near the top of all the years. Extent in winter does not correlate well with September.

Douglas, thanks for the Oregon Temperature link! I bookmarked it! Fabulous.

R. Shearer

At least a portion of a 0.75C rise over the past 100 years is due to AGW. Given that today it’s -9C and two days ago it was 12C, I hardly think that AGW is perceptible.
Of course some above have mentioned the greater warming in the arctic which seems to be real. They want you to explain the ice extent which might be lowest in the last 30 years. But it’s all happened before. The well documented migration of peoples to the arctic about 1000 years ago didn’t happen because it was colder.
