A major and historic winter storm is underway at this Wednesday morning in Argentina. Snow is falling in many parts of the country and in many areas not used to winter precipitation. Local news reports indicate snow already have been observed in the provinces of Mendoza, San Luis, San Juan, Cordoba, La Pampa and Buenos Aires.

In Bahia Blanca, a coastal city in the Southern part of the Buenos Aires, the snow storm is heavy and local authorities describe it as the worst snow event in 50 years. Roads are already blocked by snow and ice in the regional. TN news channel reports some areas of the Sierra de La Ventana could pick up even 3 feet of snow, unimaginable to the region.

Early this Wednesday afternoon, satellite pictures were showing a band of clouds advancing to the North and snow precipitation could no be ruled out in the capital Buenos Aires. In July 9th and 10th 2007 it snowed in the city of Buenos Aires for the first time in 89 years and it could snow again just two years later. Snow was also reported in the capital of Chile Santiago. MetSul Weather Center is not ruling out snow also in Uruguay.

Nevertheless a “hot red noaa spot” on the sea in front of Buenos Aires:

btw, it also shows a cold anomaly developing just along the equator line, Nino 1+2 area.

Snow storms in the Alps in summer are not uncommon, but I was surprised to see so much accumulation so low.
Here you can see a hindcast of temperature and precipitation for the last two weeks in the region:

It should be said that now it is southern winds (Foehn) and very warm

“The Great Lakes region, Prairies and Maritimes have felt the cool and wet rejection of this season the most.
A few facts: Toronto, Montreal and Winnipeg have been 2 to 4 degrees below average almost day in, day out since the season began. Halifax nearly doubled its average June rainfall. Days with more cloud cover than sun were common nearly all across Canada.”

I hear the great Atnas Sualc is winging his way from the South Pole, on
a sleigh pulled by 1000 Penguins.
He’s saying, Ooh, Ooh, Ooh, and plans on taking toys away from children all over the souther hemisphere.

Why is AMSU through the roof?
Direct quote from my father-in-law who is 65: “This is the coolest summer I ever remember….”
That was 2 days after we broke a 99 year old record low.

Also on the weather is not climate front, our friend Nate Silver offers a modest wager that some who hedge on the colder side might be interested in taking up:

I think these events are good to highlight but I fear they will be greatly overshadowed soon by the arctic sea ice decline. The ice loss is starting to accelerate and the SST anomaly chart shows bright red 5+ degree anomalies completely circling the arctic.
This does not bode well, I fear the damage will be done before evidence that we are in a natural cycle has time to surface. Once draconian legislation is passed 1) It will never be fully repealed 2) The concept can no longer be disproven. Once we have taken some action, they can simply claim (and program their models to show) that it was them who saved us. No one can ‘prove’ what would have happened had we done nothing so it will be impossible to argue.

All this “global warming” is astonishing. “Surely it is a matter of soot aerosols associated with CO2 pollution producing some negative feedbacks...”(a global warming new age scientist)

“That Global Warming sure gets around, don’t it?”
It does indeed. I’ve lived in Dubai, on and off, (mostly on) for many (30!) years. The last three years have been very strange; coolish (this year down around 4C from the normal summer average) more rain than usual, cooler winds.
Normally, in summertime we don’t use our water heaters, and find that even at 6 a.m. the water from the roof tank is almost too hot to bear; this year, and to a lesser extent last year, it is almost too cool.
I know “weather is not climate” but…………

TABER CORN, THE SWEETEST, BEST-TASTING CORN IN THE UNIVERSE , IS TWO WEEKS LATE THIS YEAR DUE TO COLD WEATHER.
ENOUGH OF THIS AGW NONSENSE.
IF THIS IS GLOBAL WARMING, WE NEED MORE OF IT.
******************************
Harry Brook, a crop specialist with Alberta Agriculture, said our spring hasn’T been very kind to most crops in the province.
“Almost all the crops in the province are way behind where they should be, by about a two-week average,” he said. “Canola should be flowering by the end of June, but we’re only seeing it flower right now.
“Corn is known as a C4 plant, which means it’s most optimal development is under hot conditions. We haven’t really had any hot weather. And when the temperature goes below 5 C, like it did at night in the spring, corn shuts down.”
This is the second year running that Mother Nature has scorned the sweet corn. Hailstorms in July 2008 cut down the harvest of Taber corn by 50 per cent last year, and what wasn’t destroyed was delayed by two weeks because of colder than normal growing conditions. The corn that was available for sale was then marked up at a higher than usual price because of demand.
“(Last year) it hailed out 130 acres totally, then another 110 acres, it stripped real good,” Valgardson said of his own harvest. “I got some out of it, but maybe 10, 20 per cent.”
Asked if the crop is getting tougher to grow as weather patterns seem to become less predictable, Valgardson answers simply, “Some. It depends on the year.
“Three years ago I started Aug. 1 and finished Sept. 8,” he said. “Last year with the hail, I never started until Aug. 28. I only had about seven, eight days of corn. This year, I expect to start around the 15th of August. And I’ll probably harvest for about five weeks.”

Sorry Anthony,
after the “Snow in Buenos Aires”, which turned out to have happened in 2007, and the “IPCC lead author” Tom Tripps, who turned out to have contributed to the guidelines on CO2 bookkeeping which is not part of the assessment reports, I have to ask:
– Which Wednesday are we talking about
– Is this projection or actually happening
I have checked a few Argentinian webcams (there are few available to English searches). Right now it is dry and clear in:
– Buenos Aires
– Tucumán
– Ushuaia
We have heavy rain in
Mar del Plata.
No snow anywhere that I could find.
Now to Bahia Blanca
windfinder reports maximum wind speed of 6bft, a strong breeze
windfinder forecasts above freezing temperatures, low precipitation, air pressure between 1010 and 1020 mbar
So, please, what is this post about?
REPLY: Weather.
Reply 2: Yesterday ~ ctm
REPLY3: as reported by MetSul in Argentina, perhaps you missed that.

Yep. July WILL be the warmest month….. EVER!
The Central Valley here in California is experiencing one of its longest runs of 100 + temps I can remember. This condition is slated to last into August. No high temp records challenged so far though. Interestingly, the humidity levels have been lower on average this summer that previous summers. I have worked outdoors in this area since 1990, and have a pretty good feel for the pulse and tendencies of the seasons. lived in the Valley since 1978, and this summer reminds me of that one. Im not saying the humidity of past summers had been intolerable, just higher than usual. I moved from Dallas to here in 78, and know what high humidity is, thank you very much. We took off from Dallas at about 7:30 and the pilot said the temp was 74 degrees. When we landed in Fresno 2 1/2 hours later, they announced that it was 86 outside. I thought they had made a mistake because it felt soooooo much nicer than that.

Yeah, well, that’s South America. It’s probably a “hot” snow. Y’all see that newest sunspeck? It’s right in the dead center. Could it be an old cycle spot?

To me it looks like the El Nino is stalling. I’ve been watching for about a month now.

and while it snows in Buenos Aires, Senator John Kerry is at it again about an ice-free Arctic:
This is from his opening comments 21 July here:
http://foreign.senate.gov/testimony/2009/KerryStatement090721p.pdf
Chairman Kerry Opening Statement At Hearing On Climate Change And Global Security.
[Excerpt]
“We are here today to discuss a grave and growing threat to global stability, human security, and America’s national security. As you will hear from all of today’s witnesses, the threat of catastrophic climate change is not an academic concern for the future.
“It is already upon us, and its effects are being felt worldwide, right now. Earlier this year, a 25-mile wide ice bridge connecting the Wilkins Shelf to the Antarctic landmass shattered, disconnecting the Shelf from the Antarctic continent. In four years, the Arctic is projected to experience its first ice-free summer—not in 2030, but in 2013. The threat is real and fast approaching.
Just as 9-11 taught us the painful lesson that oceans could not protect us from terror, today we are deluding ourselves if we believe that climate change will stop at our borders.
“Fortunately, America’s most trusted security voices—including those here today—have been sounding the alarm. In 2007, eleven former Admirals and high-ranking generals issued a seminal report from the Center for Naval Analysis, where Vice Admiral Dennis McGinn serves on the Military Advisory Board. They warned that climate change is a ―threat multiplier‖ with ―the potential to create sustained natural and humanitarian disasters on a scale far beyond those we see today.‖
“This is because climate change injects a major new source of chaos, tension, and human insecurity into an already volatile world. It threatens to bring more famine and drought, worse pandemics, more natural disasters, more resource scarcity, and human displacement on a staggering scale. Places only too familiar with the instability, conflict, and resource competition that often create refugees and IDPs, will now confront these same challenges with an ever growing population of EDPs—environmentally displaced people. We risk fanning the flames of failed-statism, and offering glaring opportunities to the worst actors in our international system. In an interconnected world, that endangers all of us.”
Geez!
You can read the entire statement at the site I indicated at the beginning of this comment.

Here in North Carolina, the past week and half has been unusually cool. That is because the temperatures have been upper 80’s instead mid 90’s. Of course, being the south, the good times won’t last. This whole summer has been abnormally comfortable in that the humidity has been way down. In reality, the weather has felt like late Spring and early Autumn except in early June.
Well, now the leaves are starting to change, and rapidly at that. It was hotter and drier last year, so that isn’t the reason why the leaves are changing. And some trees are showing color. When leaves fall off because of drought, they are brown and not red or yellow.
Although I do not know why the leaves are changing so early, I have a bad bad feeling it is going to be a brutal winter. People in North Carolina don’t know how to handle snow. However, because of the dynamics of the warm gulf stream current which shape and mold the Outer Banks and the Appalachian mountains, quite often winter weather starts off as freezing rain and sleet. So what happens is that ice covers the roads. Several years ago, we had so much sleet that it looked white like snow. Another year, it snowed several inches and then sleet fell on top of that. So much sleet fell, that it was able to support my weight on top of the snow. It sounded like I was walking on a hollow wooden floor. I have a bad bad those days are coming again. I run my own business. If I don’t work, I don’t get paid.
Are there any tree specialists out there? Can you tell me the possible reasons for leaves to change early?

Like Gore, Kerry was defeated by Bush, and this appears to have affected his mind.
