Over here on the warmer side of Puget Sound and further from the water, the high yesterday was 34 and forecast to be warmer today and even warmer the next two days. As of 1 PM it's already 33.

I've resisted getting air conditioning so far, but with warmer summers apparently permanent and my developing asthma, I've decided it's time. Heat pumps include air filters which should help with the asthma, especially with the now annual wildfire smoke.

We're currently 28.8, but it was 30.1 a little while ago.



Furnace Creek, California, reached 128.40 F yesterday. It will be interesting to see how hot they get today. You can download their weather data here. That temperature was set at 23:03 UTC, so we might see a similar temperature there in another hour or so. Having the 1913 temperature five degrees Farenheit above the second place values seems suspicious to me.

From Wikipedia
The highest temperature recorded on Earth has been measured in three major ways: air, ground, and via satellite observation. Air measurements are used as the standard measurement due to persistent issues with unreliable ground and satellite readings. Air measurements are noted by the World Meteorological Organization (WMO) and Guinness World Records among others as the standard to be used for determining the official record. The current official highest registered air temperature on Earth is 56.7 °C (134.1 °F), recorded on 10 July 1913 at Furnace Creek Ranch, in Death Valley in the United States.[1] For ninety years, a former record that was measured in Libya had been in place, until it was decertified in 2012 based on evidence that it was an erroneous reading. This finding has since raised questions about the legitimacy of the 1913 record measured in Death Valley, with several meteorological experts asserting that there were similar irregularities. The WMO has stood by the record as official pending any future investigative results. If the current record were to be decertified then the holder would be a tie at 54.0 °C (129.2 °F), recorded both at Furnace Creek and in Kuwait.[a]

Global warming has not reached Glasgow. After a pleasant spring summer is cool and WET. I had the heating on the other morning - temp 60F in living room, 62F in bedroom. Something to do with the jet stream according to the met people - does anyone know if global warming affects the jet stream? If it does my CO2 output could go up as the earth warms up because I'm not zero CO2 and the summer temperatures could be too low for elderly comfort. It also gets harder to dry washing out of doors if we have so few dry days, temptation to tumble dry or put on heating. I remember opening up the hatch to the loft because the house felt too hot in the old days when they weren't going on about global warming, now I'm thinking about year round heating.

Global warming does affect the jet stream! It gets weaker, especially in the summer. The jet stream is driven by the differences in temperatures between the equator and the poles. The areas near the poles are warming much faster than the areas near the equator, so that temperature difference is getting smaller. The jet stream is stronger in the winter, because those temperature differences are much greater than they were in the summer. However, the jet stream in winter is weaker than it was many years ago.

You can think of the jet stream as a conveyor belt, moving synoptic features like storms and high pressures along. As the jet stream gets weaker, these synoptic features move more slowly, so spells of hot, cold, wet or dry weather stick around for a longer time.

You can think of the jet stream as a wave that circles the earth with peaks in one area and troughs in another. In the summer, there are usually four or five of these waves, with six or seven in the winter. So, with four waves around the globe, the wavelength is about 90 degrees of longitude. So, if you're under a trough, you're getting cold wet weather. And, people half a wavelength away, which is about 45 degrees of longitude, are getting hot dry weather. So, for me, when we are cool and damp, our girl in Toronto is dying of the heat. We are at 123 degrees West, and she is at 79 degrees West.

It is, of course, much more complicated, but that is the general picture.

This shows the planetary waves, with troughs in red and ridges in blue.

Hear is an interactive jet stream global map. Click and drag globe to see your area. If you click Temprature it overlays the Jet stream.

Michael, Thanks for the explanation. I've got a much better picture of it now.

Thank you, well we may not get overall colder summers but if we get a cool spell it is likely to last longer (warmer spells too of course but we tend to remember the cooler ones more.) Moral: do not pack away all your winter warmer clothing - if you get a cool spell the house will cool down before it is over and you will NEED some warmer clothing unless you want to spend a fortune on heating and then feel guilty about the carbon dioxide you are releasing.

I know the other side of your guilty feeling; I am trying not to turn on the AC. Opening and closing windows depending on time of day and direction of sun. We drove up north through California's Central Valley in 41.7 C yesterday. We were heading to the Bay Area- so it was cooling when we got here. Take care everyone.

Looking forward to a few nice winter (?) days.
Some examples of whats expected.
24C in Adelaide on Friday — 8C above average
22C in Melbourne on Saturday and Sunday — 7C above average
21C in Canberra on Saturday and Sunday — 8C above average and its warmest winter day in nine years
27C in Sydney on Wednesday — 9C above average
31C in Brisbane on Wednesday — 9C above average and warmest winter day in seven years

Cooler air should gradually erode the heat across South Australia and Victoria from Wednesday to Friday, then sweep into New South Wales and the central interior by next Saturday.

The polar air mass is too far ahead for a precise forecast of the severity of the cold snap, however the system has the potential to rival the icy blasts from July.
