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!

NOAA was a big part in getting a law passed where ships have to burn a better grade of fuel as they approach land.
This kinda got my brain rolling, along with your earlier comment with N Pole cams. Thinking of air traffic more than ships.

I know Anchorage International (aka Ted Stevens airport) is well used for passengers and goods on a "over the pole" air route for a shorter trip from continent to continent. Probably other airports are also. Might be hard to separate out axis change, but wonder if a study's been done that looks at effects of the presence and increase in the past few decades of air traffic going over the North Pole in terms of its capability to warm the atmosphere near and above the Pole.

its just because you the weather fan there wanted rain.
So of course you wouldnt get it.


LOL-- That's what I thought last night.

However, the area that got rain is normally drier than San Antonio.

When they seed they go into rain clouds.

Without the seeding the area that got 1 in of rain may have gotten drizzle.

This is the latest wave that was introduced just on the African coast. It looks like a dry wave.

COMPUTER MODEL DATA AND SURFACE OBSERVATIONS ACROSS FAR WEST
AFRICA SUGGESTED A TROPICAL WAVE MOVING OFF THE COAST OF
MAURITANIA AND SENEGAL EARLY THIS MORNING WITH AXIS ANALYZED
FROM 18N16W TO 11N17W. NO CONVECTION IS CURRENTLY ASSOCIATED TO
THE WAVE DUE TO HIGH REFLECTIVITY VALUES DRY/SAHARAN AIR NOTED
ON METEOSAT-9. THEREFORE...AS THE WAVE CONTINUES EMBEDDED IN
THIS ENVIRONMENT...THE PLACEMENT OF THE AXIS MAY VARY OVER THE
NEXT FEW DAYS.

AOI in the Bahamas is what I'm watching today, and here's why: Low shear, warm SSTs, moderate mid-level vort, and 850 vort expanding in that general area. Still unlikely to develop, but the best thing we have to watch now as evidenced above.

yes, it does. it is important to manage the impact of conspiracy as it impedes progress in dealing with the reality.
what if the 'big bad' government attempts a sincere effort at controlling the impact to our environment; how is it going to take charge when it's citizenry believes it to be the culprit of evil by means of intention?

yet, this is exactly what is occurring by way of misinformation regarding multiple economic and social policy fronts!! progress is dead because of a full-on narrative of lies. it will be a massive defeat to us all if the same game is played regarding environmental policy... oh wait, that Is what is happening..


let's cause panic and lose more people with that than what the actual event would have caused...i am not saying gov is always great but ya have to figure the risk when leaking the truth...

Looks like we had the same thing in mind models do not always catch on so we might have a surprise there is plenty of moisture available.

The answer is because you frame them in your mind as an argument.

Its not an argument just a back and forth that is sometimes infuriating.

But if you look at it as a fun look through a window of others thoughts,it can put a smile on your face.


im smiling, its a twisted grimace.
I suppose you are right though.

BTW, what is spathy, is that a made up word?

Dont you just love those kind of storms when they arent damaging?

Its a tropical thing that is sorely missed between seasons.

is weather modified weather modification?
i'm seeing two interpretations to this question:
1) that the result of modified environments without intention is wx. mod.
2) that the result of modified environments with intention is wx. mod.

i get annoyed with a certain user here, because he/she hides behind the ambiguity of statement 1) and Clearly implies statement 2).

it is evident that humans impact climate, climate drives weather, and weather has been modified under such human-impacting conditions. however, a conspiracy of intention doesn't gain any traction beyond seeding clouds from what i can gather.

Wow: More from South Texas Weather Modification.

In bold is the possibly explanation for last night's dry slot over San Antonio?

LOCAL WEATHER -- MONDAY, JULY 16, 2012

Seeding operations:


Seeding operations occurred Sunday afternoon and early evening with two flights launched. Numerous clouds were seeded in Bee, Live Oak, McMullen, Karnes, Atascosa, Frio and Medina counties.
A total of 66 flares (two hygroscopic, 64 silver iodide) were used to treat the clouds.

A special restriction was put in place yesterday which limited flights within a 30 mile radius of San Antonio so some clouds were not able to be seeded.

Seeding operations are possible today through Wednesday.

No, I don't live in that area. I first learned about it here on the WU. Dr. Masters and Christopher Burt both mentioned in posts, plus many, many bloggers here provided personal histories and photos of the damage.

Also, every major news network provided extensive coverage of this historical event, which occurred two weeks ago.

Next time you post something, PLEASE check the date. The Washington Post article you posted was referring to something that happened two weeks ago.

The largest component of hydrocarbon exhaust is water vapor.

There are MANY more ships than you think out there. And wxmod isn't going on about the cloud deck (which is normal), but the lines of clouds to the west of that.


no he implicated the cloud deck that would "blow on shore"
the lines are just ships and planes.
Water vapor is the main ingredient as a byproduct of combustion.
