From the “weather is not climate department”, while the east gets a heat wave, southern California sets chilly records in July over several days. Both Los Angeles and San Diego NWS offices made a number of record event reports, which I’ve compiled below along with an LA Times story. Much of the Southwest was cooler as seen in the map below:
Of particular note from San Diego:
[THURSDAY JULY 8th] RECORD OF 64 DEGREES IN SAN DIEGO TIED THE LOWEST MAX TEMPERATURE EVER RECORDED IN THE MONTH OF JULY WHICH LAST OCCURRED IN 1912.
LA Times: What summer? Record cold at LAX as July gloom continues
July 10, 2010
Unusually cold temperatures in Southern California continued, with Los Angeles International Airport setting a record low on Friday.
LAX got to only 67 degrees, breaking a record set in 1926, according to the National Weather Service.
Temperatures are expected to stay fairly cool Saturday, with highs around 70 on the coast and in the 80s inland. Conditions will be a bit warmer on Sunday, according to the weather service.
July has turned out to be cooler than normal.
Instead of daytime highs approaching the mid-80s, downtown L.A. has experienced temperatures in the mid- to high 70s. From June 1 to July 5, daytime and nighttime temperatures have averaged a relatively cool 69.8 degrees.
That makes that stretch one of the cooler ones for that time of the year in the last 10 years, just slightly warmer than the same period in 2004 (69.4 degrees) and 2002 (68.9 degrees). The cooler ocean air early in the day has a moderating effect on daily temperature conditions. And low-lying clouds have been tempering the sun’s heat.

When we get a string of hot days it’s called a heatwave.
There is no equivalent term for a string of cool days.
Since our weather regime looks to be trending that way, may I suggest that a string of successive unseasonably cool days be called “a fonzie”.
Because Fonzie was cool, donchaknow.
I second papertiger, that a string of successive unseasonably cool days be called “a fonzie”.

“When we get a string of hot days it’s called a heatwave.
There is no equivalent term for a string of cool days.”
WA Today.com.au calls it a cold snap.
“Perth has shivered into its 14th straight day of sub-five degree days, with tomorrow’s forecast showers expected to thaw the cold spell. It’s the longest running cold snap in 66 years.”
Also :
“St Vincent de Paul spokeswoman Lucinda Ardagh said the charity had received 3000 calls in the past eight weeks from about 10,000 people seeking help. Of those 34 per cent wanted assistance with their power and gas bills this winter.
She said that was a 46 per cent increase in demand for utilities assistance compared to this time last year.”

Temps here in San Diego have been almost exactly average – for early January! A couple of days San Diego also had an incredibly short thermometer, with only 3 degrees difference between the low and high temp. That’s a very strong indication of just how thick the marine layer has been when basically no radiational heating occurs during the day!
But finally today the sun did come out for a little while except for right along the coast. Definitely the coldest start to July in history for San Diego and vicinity. But it also means a significant savings in electric bills for people a few miles inland where they normally need to run their A/C units this time of year. Some places inland have been 15 to 20 degrees below normal meaning the days have been quite pleasant!
Out here in the east, we’re having 2 summers at once 🙁 But I’ve always said, when it’s unusually warm in one place, it is unusually cool someplace else. That heat came from somewhere….

I like a ‘Fonzie‘!!!
My alternative suggestion would be to call it a ‘cold straight‘, but then I do play quite a bit of poker. If this were to be adopted, then we should perhaps rename a heat wave a ‘hot flush‘.

It doesn’t appear to be a measle. If you click on the map, then on high temp records (or just hover over a dot), you would have found it was “TX; Dell City, 5 miles SSW of; Tue, 6 Jul 2010; 107; 104 in 1994”
I’ll defer to you and folks in Texas to describe/defend the Dell City outskirts.
A lot of the reporting stations at hamweather.com are not well sited or maintained, so the data needs to be taken with a grain of salt.
The low max temp records east of there are mostly from July 9th & 10th. Wow – living in New Hampshire, I never thought I’d be envious of July temps in Texas!
Remember, according Michael Mann, the heat wave on the eastern US is proof of AGW. Therefore, by his logic, the cool weather on the western US is an aberration; not climate but simply weather. Of course, what Michael Mann conveniently ignores is the effect La Nina has on the jet stream.
DirkH says:
Hot in the east. Cold in the west. But between the east and west, Minnesota weather has been normal for the last month or so. Not too hot, not too cold, and just the average amount of rain.
The east coast may be having warm temps now but overall it has been a cool year here in central North Carolina compared to 2004. several Snowstorms this winter, we see snow about every five years. And it was downright cold this spring and we did not see normal temperatures until June even so we are not seeing the temperatures we did prior to 2004 (haven’t broke a hundred yet)
For the year 2004 I count 43 days over ninety F and nine days of 98F by July tenth compared with just 26 days over ninety F and four days of 98F for 2010 for the same date, July tenth.

Thanks. I did not mouse-over…. my bad.
Douglas adams was right – mice can do anything 🙂
So the West is record low and the east is record high. My stats book would say that averages out to normal. But I’m sure it’s all due to AGW.
It’s no wonder S Cal is cold, the Pacific ocean temps there are well below avg. And the polar jetstream is still pushing far enough south to keep NW winds blowing onshore in those areas. The southwestern US heat-bubble is confined well into the interior.
This may also be currently cutting off monsoon moisture that normally enters AZ & western NM, blocking it eastward toward east NW & TX.
Gore effect weather oscillations. When the Jolly Green Giant arrives all kinds of cooling transpire. Cooling with even record snows. If he bought a pad out there, he may be in the area and that alone causes severe temp drops.
There were even chances of Goreflakes at mid level elevations.

Chicago area has been very mild for this time of year….I think the “heat wave” has moved on, so where are the warmists lately?
**********************************
VILLABOLO:
Right here CRS. Where are you as far as the ENTIRE WORLD is concerned?
What I’d like to do is inform you that record hot temperatures have outnumbered record lows. Have you taken the trouble to ascertain how much of the Earth is hotter than average compared to colder than average? Or is this a faith based assumption?

REPLY:
Sr. V, I’ve been involved in greenhouse gas mitigation since 1979, concentrating on biomethane production from cattle & manure ponds. I’ve published, won awards and know more about this than many who post on RC etc. Some of my lab & field work was used by the UN to develop the science of the Clean Development Mechanism under Kyoto.
With that in mind, I was much more concerned about warming until recently, when I gave it some very hard thought and studied the record in depth. The models don’t add up nor make sense. Too many variables & influences (solar activity, historic warming/cooling, cloud formation etc.) are conveniently deleted to create a “party-line” story of AGW.
There are far bigger problems for the world, including mercury deposition onto land & into the oceans, where it accumulates in the food chain. The oceans are being stripped clean of anything with fins by the Chinese, Russians, Koreans & others (US included), and our agricultural practices are totally unsustainable.
The world doesn’t need any more economic damage from imposition of carbon controls, if the powers want to reduce carbon, they should stimulate innovation in low-carbon energy systems. So far, only the big conglomerates like GE and Siemens are slurping up that money. Stay cool, the sky isn’t falling.
So what? Right now, Europe is experiencing a prolonged heat wave, and I’m sure there are many other regions seeing temperatures well above average.
REPLY: Yes and to see why, see the top post now on WUWT – Anthony
When it is colder, it is just a “snap” however long the duration of the cold, and when warmer it is a “wave”, however short the period of warmer temperatures. The going from zero degrees F to 25 degrees below zero F is termed “cooler”, and going up a single degree is termed “hotter”.
It’s been relatively cold in Western Johannesburg over the last day or so, a High of 9ºC today and Accuweather predicts -3ºC tonight and -5ºC for Thursday night. This is our second severe cold spell in a month or so. I know it is purely anecdotal and of no significance as evidence, but this year reminds me strongly of the winters when I first moved to the Transvaal Highveld in the mid eighties. My garden has been badly nailed by black frost for the second time in three years, before 2008 I’d only experienced one once in a decade and a half.
P.s. Thanks for the World Bank money for the shiny new coal fired PowerStation.

villabolo says: “[…]What I’d like to do is inform you that record hot temperatures have outnumbered record lows. […]”
Yawn. Here we go again. Any data to back that up?
It doesn’t matter. The thermometers are not distributed in such a way that the raw counts can really be compared anyway. So we have a lot more thermometers at Airports now than in the past, and a lot more in major urban tarmac jungles. OK, I’d expect more ‘record highs’ just from nothing changing.
But what is clearly the case is that it’s July, and cold enough at night I have to button up the house. For the last few decades in July we were trying desperately to get the house temp below 80 F (wife gets headaches from the AC…)
Further, I’ve harvested ONE tomato of about 2 inch diameter and it was only barely ‘ripe’. By mid-July I’m usually getting a colander full at a clip. Oh, and the squash are still being lazy too. I’ve got some 45 day squash that are presently on their 60 th day… Did get about one handful of green beans…
If it needs heat, it just is not growing.
But hey, just a year or so ago Hansen had us breaking a 115 year record heat in the west… Just because the temperature records were not falling, that’s no reason to thing it wasn’t the hottest ever. At least in the land of “climate science”…
Bastardi predicted a warm summer on the East coast, and was right. Now he’s predicting a darned cold just about everywhere next year. I’m going with Joe. He’s got his head on straight and he knows how to use it.
FWIW, since climate is the derivative of weather (change of weather over time) and since weather is chaotic, climate is chaotic. Chaotic systems are refractory to mathematical analysis and so any math based model of them is doomed to failure.
It just is not possible to “model climate change” with a computer. Sorry.
You can however model the data you have. The only problem with that is that modeling data has zero predictive power. And with each major data update you need a new model optimization. Sorry again.
But it is really great for misleading folks and putting on a good show.
(Just finished a very good book on the philosophy of mathematics. One of the examples used of systems where math fails due to chaotic systems was weather… “Is God a Mathematician?”).
“But it is really great for misleading folks and putting on a good show.”
And stealing people’s money.
