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.

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.

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

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.

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.

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.

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

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

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

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.

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

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”.

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)

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

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).

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

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:

They are both the same… but of course you knew that.

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
December 31, 2010 6:19 am

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.

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.

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

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
