Death Valley records a low of 107°F (41.7°C): a world record
On Thursday morning, July 12, 2012 the low temperature at Death Valley, California dropped to just 107°F (41.7°C), after hitting a high of 128° (53.3°C) the previous day. Not only does the morning low temperature tie a record for the world's warmest low temperature ever recorded, the average temperature of 117.5°F is the world's warmest 24-hour temperature on record. According to weather records researcher Maximiliano Herrera, the only other place in the world to record a 107°F low temperature was Khasab Airport in the desert nation of Oman on June 27, 2012. The previous U.S. record high minimum temperature may be a 103°F (39.4°C) observed in Death Valley, California in 1970. The NWS lists a July 5, 1918 low temperature of 110°F as the official highest minimum temperature recorded in Death Valley. This temperature is disputed by Mr. Herrera, who says the temperature that night was not monitored and passed from 60°F to 110°F then to 60°F again.

Wednesday's high of 128°F (53.3°C) was the 10th hottest temperature in U.S. history, and the hottest temperature measured in the U.S. since July 18, 2009, when Death Valley recorded another 128° reading. The only hotter temperatures in U.S. history were all measured at Death Valley, the most recent one being the 129° measured on July 6, 2007. The all-time high for Death Valley is the 134° reading of July 10, 1913.
Temperatures have cooled considerably at Death Valley over the weekend, and the forecast for Monday calls for for a downright chilly high of just 110°. That's sure to be a disappointment for the ultramarathoners in the grueling Badwater Ultramarathon, which begins Monday in Death Valley. Covering 135 miles (217km) non-stop from Death Valley to Mt. Whitney, CA, it is the most demanding and extreme running race offered anywhere on the planet. I'm sure they would have liked to have had the distinction of running their race last Wednesday and Thursday, during the hottest 24-hour period ever recorded on the planet!

Millions of people in a swath of states along the East Coast and farther west went into a third sweltering day without power Monday after a round of summer storms that killed more than a dozen people.
The outages left many to contend with stifling homes and spoiled food over the weekend as temperatures approached or exceeded 100 degrees.
Around 2 million customers from North Carolina to New Jersey and as far west as Illinois were without power Monday morning. And utility officials said the power would likely be out for several more days. Since Friday, severe weather has been blamed for at least 18 deaths, most from trees falling on homes and cars.
The power outages had prompted concerns of traffic problems as commuters took to roads with darkened stoplights. But throughout northern Virginia, there was less traffic than normal in many places Monday as federal workers took advantage of liberal leave that was put in place for the day.
To alleviate traffic congestion around Baltimore and Washington, federal and state officials gave many workers the option of staying home Monday. Maryland's governor also gave state workers wide leeway for staying out of the office.
"It was less traffic," said D.C. resident Rob Lavender, who commuted to Arlington County from the district. "It's more hectic on a regular day."
There were more than 400 signal outages in Maryland on Monday, including more than 330 in hard-hit Montgomery County outside the nation's capital, according to the State Highway Administration. There were 100 signal outages in northern Virginia late Sunday afternoon, and 65 roads were closed, although most were secondary roads.
"If you have to drive or need to drive, leave yourself a lot of extra time," Maryland State Highway Administration spokesman Charlie Gischlar said. "There's going to be delays."
Some drivers resorted to ingenuity to get to work. On a residential street in suburban Falls Church, Va., just outside Washington, downed trees blocked the road on either side. Enterprising neighbors used chain saws to cut a makeshift path on one side, but the other remained completely blocked by a massive oak tree.
"They kind of forgot about us out here," resident Eric Nesson said.
Still, residents took the aggravation with good humor. Posted on the oak tree was a sign saying: "Free firewood you haul." The tree lay across a smashed Ford pickup truck, with a sign reading: "For SALE. Recently lowered."
Meanwhile, Coast Guard officials say they have suspended the search for a man who disappeared early Saturday while boating during the storm off Maryland.
On Sunday night in North Carolina, a 77-year-old man was killed when strong winds collapsed a Pitt County barn where he was parking an all-terrain vehicle, authorities said. In neighboring Beaufort County, a couple was killed when a tree fell on the golf cart they were driving. Officials said trees fell onto dozens of houses, and two hangars were destroyed at an airport in Beaufort County.
The damage was mostly blamed on straight-line winds, which are strong gusts pushed ahead of fast-moving thunderstorms like a wall of wind.
Elsewhere, at least six of the dead were killed in Virginia, including a 90-year-old woman asleep in her bed when a tree slammed into her home. Two young cousins in New Jersey were killed when a tree fell on their tent while camping. Two were killed in Maryland, one in Ohio, one in Kentucky and one in Washington.
In West Virginia, authorities said one person died early Sunday when the all-terrain vehicle they were riding hit a tree that had fallen over a road.
For survivors, it was a challenge to stay cool over the weekend.
From Atlanta to Baltimore, temperatures approached or exceeded triple digits. Atlanta set a record with a high of 105 degrees, while the temperature hit 99 at Ronald Reagan Washington National Airport just outside the nation's capital. With no air conditioning, officials urged residents to check on their elderly relatives and neighbors. It was tough to find a free pump at gas stations that did have power, and lines of cars snaked around fast-food drive-thrus.
"If we don't get power tonight, we'll have to throw everything away," Susan Fritz, a mother of three, said grimly of her refrigerator and freezer. Fritz came to a library in Bethesda, Md., so her son could do school work. She charged her phone and iPad at her local gym.
Power crews from as far away as Florida and Oklahoma were on their way to the mid-Atlantic region to help get the power back on and the air conditioners running again. Even if people have generators, the gas-run devices often don't have enough power to operate an air conditioner.
And power restoration was spotty: Several people interviewed by The Associated Press said they remained without power even though the lights were on at neighbors' homes across the street. In Maryland, Gov. O'Malley promised he would push utility companies to get electricity restored as quickly as possible.
"No one will have his boot further up Pepco's and BGE's backsides than I will," O'Malley said Sunday afternoon, referring to the two main utilities serving Maryland.
In Waldorf, Md., Charles County emergency officials handed out free 40-pound bags of ice to anyone who needed them. Among the takers was Ann Brown, 47, of Accokeek, Md., who had stayed in a hotel Saturday night because her house was without power.
She went to a cookout in Upper Marlboro, Md., on Saturday after family members decided to cook all the food in the freezer rather than let it go bad.
"Whatever they had, that's what we ate, and it was great," Brown said.
Whether she makes the commute to work Monday will depend entirely on how comfortable the office is.
"If they don't have power, I'm not going. But if they have power, yeah, I'm going in, to be in the air conditioning all day," she said.

Still putting out mulitople lows
A grid has lines that cross at perpendicular angles. Not parallel straight lines that somehow magically line up as the route between Asia and the US west coast.
I'm not so sure about that actually. As far as I know the subjects discussed on the blog are outside what could be expected of a secondary education--not because of difficulty but because of specialization. Yes, the younger people on the blog contribute and benefit, but kids will come to this blog regardless of their educational background, superior or otherwise, if they have the interest (and internet access). I think it is the desire to learn and witness that makes the blog go.
If the desire is there, you just can't deny it--like Chi Chi Rodriguez learning golf.
"Rodríguez would take a branch from a guava tree and turn it into a golf club. Using a metal can as a "golf ball", he would practice what he had seen the "real" golfers do, teaching himself how to play golf. By the time he was nine years old, he was proficient at golf and in 1947 at the age of 12, he scored a 67."
Grid?
I see transpacific flights and N-S flights, if that amounts to a grid, good for you, but its a terrible grid fyi.
That was 2 weeks ago....
Somehow or another, i am getting the impression that this is NOT happening now.
The huge man made clouds are thousands of miles long and dozens of miles wide. There are hundreds of them covering a sky area the size of the whole United States. This is from a satellite photo, not from someone's imagination. Whether this is intentional geoengineering or unintentional and cause by shipping, it is still geoengineering by humans on a massive scale. It is changing the world wide weather and the air quality all across the planet. Just the facts.
Here's a blog about dead and dying trees worldwide, linking carbon and ozone pollution to this ongoing calamity.
There's an extensive set of links to scientific papers about tropospheric ozone and air pollution caused tree and vegetation mortality.

Various militaries, korea, russia, alaska, Hawaii?
Heck the flights could be from S America.
The point is there is no wx mod going on and there is no grid
Were you sleeping two weeks ago when the Derecho stretching from Illinois to the Atlantic Coast knocked out power to millions.
WAKE UP~!!
Actually, to show you how unobservent you are, these clouds are caused by ships, not aircraft, and are at sea level. You need to study infrared photos to see that.I strongly suggest you pour over thousands of satellite photos per day before you comment here.
Not so exciting like yesterday.
The parts I disagree with on your statement are that they are "changing worldwide weather", and "just the facts".
While they could be theoretically be changing the weather, there are other things that we as a species have done that changes the weather much more drastically. Between our propensity to pave over everything, cut down trees, and burn forests to clear land, some intermittent high clouds are not going to make a gigantic impact.
Secondly, showing a set of satellite photos and hypothesizing all of these things from them is far from a proper burden of truth.
So you "pour over" thousands of satellite photos daily?
And what do you pour over them? Cream? Doesn't that ruin the photo?
Thing is, I actually do think that the amount of contrails (vapor and exhaust) being released into our skies have an impact on cloud formation (suppression and creation) so they do impact weather patterns. I just don't think global geo engineering plans / efforts are nearly as organized and capable as wxmod seems to believe they are.
you mean the sheets of clouds?
its kinda typical of oceans.
definitely no wxmod
from 8 am NHC Discussion
...CONVECTIVE PRECIPITATION...
SCATTERED MODERATE TO ISOLATED STRONG FROM 8N TO 11N BETWEEN 45W AND 52W... ISOLATED TO WIDELY SCATTERED MODERATE FROM 6N TO 11N TO THE EAST OF 25W...FROM 7N TO 11N BETWEEN 25W AND 40W AND TO THE SOUTH OF 10N BETWEEN 52W AND 60W.
Modify your post.
Or watch from the outside, permanently.
I had to chuckle at this... First of all, ships don't cause clouds. And as jeffs713 said in comment 424, pouring cream over thousands of satellite photos per day doesn't help you interpret them any better.
so i should just leave here and stare at tons of sat photos all day....and then maybe after number 2012 then ill become as delusional as you are?
no thanks
there is no wxmod
not large scale every day like you guys claim
of course there is wxmod, the chinese did it in '08, they are trying to do it on hurricanes.
The point is, there is nothing going on like the stuff you pointed out, where we make massive sheets of clouds in the pacific
Not only do they provide 4-5% of CO2 worldwide..
Exhaust emissions from ships are considered to be a significant source of air pollution, with 18 to 30 percent of all nitrogen oxide and 9 percent of sulphur oxide pollution.[12] "By 2010, up to 40 percent of air pollution over land could come from ships."[13] Sulfur in the air creates acid rain which damages crops and buildings. When inhaled the sulfur is known to cause respiratory problems and even increase the risk of a heart attack.[13] According to Irene Blooming, a spokeswoman for the European environmental coalition Seas at Risk, the fuel used in oil tankers and container ships is high in sulfur and cheaper to buy compared to the fuel used for domestic land use. "A ship lets out around 50 times more sulfur than a lorry per metric tonne of cargo carried."[13] Cities in the U.S. like Long Beach, Los Angeles, Houston, Galveston, and Pittsburgh see some of the heaviest shipping traffic in the nation and have left local officials desperately trying to clean up the air.[14] Increasing trade between the U.S. and China is helping to increase the number of vessels navigating the Pacific and exacerbating many of the environmental problems. To maintain the level of growth China is currently experiencing, large amounts of grain are being shipped to China by the boat load. The number of voyages are expected to continue increasing.[15]
MY burden of proof is contained in the satellite photos. You don't have proof to say that "some intermittent high clouds are not going to make a gigantic impact"
then you would stop memeing
wxmod!!!!! jk.
shear comes and goes, there is a high you know
you read to deep into things, no wonder you have a palm as your pic
So because it is on a biased internet site with a clearly defined agenda, with vague sources and ZERO citations... it is true?
Hold on a sec, I need to finish making my site about how alien plant seeds in our brains to make us crazy, so it is easier for them to take us over on 12-21-2012.
OMG!
Now it all makes sense!
