The July 2009 temperature for the contiguous United States was below the long-term average, based on records going back to 1895, according to a preliminary analysis by NOAA’s National Climatic Data Center in Asheville, N.C.
The average July temperature of 73.5 degrees F was 0.8 degrees F below the 20th century average. Precipitation across the contiguous United States in July averaged 2.90 inches, which is 0.14 inches above the 1901-2000 average.

- An abnormally strong, persistent upper-level pattern produced more than 400 record low minimum temperatures and 1,300 record low maximum temperatures (lowest high temperature) across the nine-state area that make up the Central region.
- Ohio, Iowa, Illinois, Indiana, West Virginia, and Pennsylvania experienced their coolest July on record. Kentucky, Missouri, Wisconsin, and Michigan each had their second coolest July on record, while Minnesota and Tennessee had their third coolest July on record.
- Death Valley, Calif., set a new monthly average maximum temperature at 121.3 degrees F. Temperatures in Death Valley reached 120 degrees F or higher for 22 days, beating the old record of 19 days.
- Several western locations recorded their all-time warmest July. Seattle-Tacoma Airport had an average July temperature of 69.5 degrees F, which was 4.2 degrees F above average. Seattle’s high temperature of 103 degrees F on July 29 is an all-time record. Alaska posted its second warmest July, Arizona had its third warmest, while New Mexico and Washington had their ninth warmest.
- Based on NOAA’s Residential Energy Demand Temperature Index, the contiguous U.S. temperature-related energy demand was 13.3 percent below average in July. Much of this can be attributed to cooler-than-average conditions in the heavily-populated Northeast.
In a related note, UAH has produced this map which not only shows a cooler than normal eastern USA,but many other cool spots around the globe. Oddly, Antarctica appears to be the major contributor to above normal temperatures and the 0.41C global temperature anomaly jump in July 2009.

July is one of the coldest months in Antarctica. What is the reason for this sudden jump in the local temperature anomaly?
Maybe Steig and his colleagues just have signed an agreement with the leaders of several Emperor Penguin colonies to raise local temperatures by as much as possible…
I’ve posted the July OI.v2 SST anomaly data. Global SST anomalies dropped slightly in July to +0.28 deg C:

Monthly NINO3.4 SST anomalies continued to rise to +0.86 deg C.

The weekly NINO3.4 SST anomalies have dropped a small amount over the past few weeks.

The antarctic anomalies demonstrate the misleading possibilities of the “anomalies” color maps.
It is winter there and the “normal demperatures are below -60C. To have an anomaly of 7.5C means that the temperatures are there now -52.5C . If you spit, it still freezes in the air. There is no sun at this time of the year so the only heat input can be by convection or by geothermal sources. Convection means that the -60C air has migrated north to change the temperatures there by a few degrees colder ( temperatures and anomalies are not propagated linearly ).
In the case of land-based temperature records the penguins established their colonies next to the Stevenson screens (as they have promised in their agreement with Steig).

Good call.

Now is the winter of my discontent.
The link was good but contained within this is better.

Mr Watts
I see a measuring station in the distance.
To understand the non linearity of temperature and anomaly measures in geographic distributions, follow this gedanken experiment:
Have a kitchen at 20C
Light the electric stove to boil something. The anomaly in the pot is +80C.
The anomaly in the room might go to 0.1C, growing with time.
Other:
Take the freezer at -25C. Open it. It gets a positive anomaly of +5C the more the longer you leave the door open.
The room might go from 20C to 19.9C, maybe, a negative anomaly of 0.1C.
So, volumes, density, convection etc have to be taken into account before any sense can be made of temperature anomalies even in a simple kitchen.
Th high LT’s around Antarctica indicate to me that this is the little studied southern ocean is currently shedding a lot of heat during southern hemisphere winter.
This is a strong indicator of background cooling, despite the current mid latitude mild conditions over the oceans.
Let me be the 1st to send an overdue chill down the back of all those smug warmists:
A warmer than normal Antarctic in the dead of winter is not good news.
It means increased precipitation which, coupled with a colder Northern Hemisphere, that ocean levels are going to take a big hit.
Sea levels plunge. The warming alarmists are going to look dumber than dirt.:
Playtime is over.
Hurry up with the plans to deepen the Suez and Panama Canals.
Now that will put one heck of a damper on Global Trade.
It will also regionalize the balance of power.
Mike Jonas (23:14:55) :
The warmists are in for a rude awakening.
Thier worst nightmare is not what they have imagined.
It’s having the world turn reddened eyes toward you and the bony finger is extended.
I see the bright red for Washington state.
Just across the border in Vancouver, BC, we hit the highest temperature EVER recorded in late July. It was dreadful. But thank goodness: The furnace has abruptly morphed into a freezer. Temps quickly plunged to less than HALF of what they were. Such relief. Rainy +15C makes for MUCH clearer thinking and far more comfortable outdoor rec. Even Yellowknife (Northwest Territories) was worse off today: 8 degrees warmer. Looking forward to a cool & rainy fall.
Only weather, but yet another sign natural global cooling.
I have 2 questions:
1. If one factors in the poor siting of weather stations, would this not mean that July was actually colder than anything this country has seen in a long time?
2. Has Al Gore been preaching GW near Chicago lately?
UAH chart puzles me. July sea ice down there, though there was a dip, appears strong.

And Unisys has consistently shown it’s cool around Antarctica. Much like today’s chart:

UK Sceptic (01:07:13) : We will also face a chronic water shortage in the future. Anyone living with the British climate will understand that the only chronic shortage we are facing is political reality…
Pardon? Water shortage? In a country surrounded by seas when desalinization is cheaper than a water pipe from the mountains 100 miles away? Water shortage, when the last time “mum” was “home” it rained every day except July 9, I think it was? (It was a long summer, from August 3 to the 5th 😉 I think she said…)
I live in one of the “darkest blue” states. So far, only a few days have felt like summer (mainly the last few). Otherwise, more like early fall.
In other words, the local lack of heat is very noticeable. Sincerely, I’ll take global warming any day. But, I imagine the “warming” trend will be flat lined for the next decade or so — we’ll see in 2020 if that is true — meantime, ups and downs.
We need to stop with the weather reports already…it makes us look stoopid…Focus on the farmers and the increase of plant life…it is happening as we post.

Good call.
Thank you….And to the point…Oh how I wish science would return to such simplicity….
Jackson TN had its coolest July ever recorded. Details are here: http://jacksonweather.wordpress.com/2009/08/01/july-2009-jacksons-coolest-july-on-record/
Our tomatoes and potatos just got hit with LATE BLIGHT yesterday. We are in the Poconos of Northeast PA. Most of the U. S. East Coast has been hit with this.
This has destroyed most of both crops.
This is the same blight that caused the Irish potato famine of the early 1800’s – – which also coincided with a deep solar minimum like the one we are experiencing now.
E.M.Smith (02:35:07)
“Pardon? Water shortage? In a country surrounded by seas when desalinization is cheaper than a water pipe from the mountains 100 miles away?”
Here in Florida, USA we have a state with ocean on three sides, a major river, and the fact that the state is a swap. Dig 10 feet in my back yard and you will get wet. We are told we have a “water shortage”.
Go figure.
This is not a surprise.
Can anyone confirm the blub I saw on Icecap that indicated Antarctica had the coldest average July temp recorded?
I am nothing more than a Jafo, just another freaking observer. And here is my observation. I think that that dudes hypothesis about the sun being a shrunken star is (for a lack of a better term) right on. I wish that I knew his name so as to give him credit but I just normally absorb information and log it in and don’t concern myself where it came from.
He proved in his theory that the sun has a solid core and that the energy around it is akin to the atmosphere to our planet….Its energy is like our cloud system and comes from within. It is not influenced by extraterrestrial forces.
He claimed that the solar spots/flares are just natural occurrences that happen during its life cycle (albeit a very long life cycle). And that the lull that we are seeing now is hppening because the center mass is cycling into an adjustment phase that is disrupting the outer surface of Sol. It is now readjusting itself into the proper place that natural science (or God) said it should be in. At the same time, the gravitational force (no one out there can explain that can you?), has lessoned on our planet and we are starting to see the effects in the earthquakes that are happening. They are happening around the major plates between the americas and asian landmass. As the solar forces decrease our earth will shift. Opposite from the theory that an active sunn predicts earthly movements.
I see the pacific plate shifting/spinning (counterclockwise) because of the lack of solar gravitational forcing on our planet (which also means a shift away from our solar orbit), almost like one would back a person battling in a game of indian wrestling. Something has to give.
And if I am wrong, so be it….No harm no foul right????? But if you are so inclined, please send $$$$’s.
Jimmy Haigh (23:09:14) :
So it’s been a cold July – even with biased (to the high side) temperature readings.
Antarctica just looks wrong.
Antarctica just looks damn cold – well Dome Argus anyway – just hit below -75C again:
http://www.aad.gov.au/weather/aws/dome-a/index.html
Regards from your old home town, where it is about 15C and has just started to rain.
Yet another example of coolist alarmism. The potato famine started in 1845, the same year as the peak of the solar maxima. There was no deep solar minimum in the 1840’s at all! The fungus responsible Phytophthora infestans was probably introduced to Ireland in 1844 from South America.
Fools the lot of you, clearly this is just weather and not climate!! Climate is when it gets warm and weather is when it gets cold – you silly silly warmists cherry picking the data once again! Just look at all that lovely stiegian red warming around the southern latitudes! See that – now BELIEVE!
As for the Arctic – don’t you know it’s not about extent – it’s all about multiyear ice and thickness as measured using the now standard measure of carlinprobes using randomly predetermined points.
