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!

found this on yahoo news..THIS could be serious if it continues,food prices could soar.....................

CHICAGO (Reuters) - Scattered rains over the last 24 hours provided little relief for U.S. Midwest corn and soybean crops that are rapidly deteriorating in the worst drought since 1988, and the forecast is for scant rain for the next two weeks, meteorologists said on Saturday.

"Overall the rain yesterday won't put a dent in the drought because they were spotty hit or miss kind of rains. Certainly some isolated areas will benefit, but it was not a significant drought buster," said AccuWeather meteorologist Dan Pydynowski.

Thunderstorms on Friday left from 0.25 inch to 0.50 inch of rain in portions of eastern Iowa and northern Illinois, including Chicago, with isolated amounts up to one inch, meteorologists said.

There were similar showers of "0.25 inch or so" in portions of parched southern Indiana and southern Illinois, Pydynowski said.

Some showers were expected in the Midwest from Saturday through the end of next week, MDA EarthSat Weather meteorologist Steve Silver said. But the minimal amount of rain accompanied by high temperatures will continue to stress crops.

"There won't be enough rain to dent the drought," Silver said.

Only about 25 percent of the Midwest received some rain on Friday with most of the moisture in Wisconsin, Minnesota, eastern Iowa, northeast Missouri and a few spots in central and northern Illinois, said Joel Widenor, meteorologist for Commodity Weather Group (CWG).

"There was some local relief and about 20 to 25 percent of the Midwest will see similar rains during the next 1 to 5 days," Widenor said.

Meteorologists agreed that the combination of high temperatures and minimal rainfall will continue to erode production prospects for the 2012 corn and soybean crops.

"The general pattern is still hot and dry, especially in the west half of the Midwest. High temperatures in the west will reach the 90s (degrees Fahrenheit) to 100s during the next week and the low to mid-90s in the east," Widenor said.

Drought and heat led the U.S. Department of Agriculture on Wednesday to slash its U.S. corn production forecast to 12.970 billion bushels, down from its previous outlook for 14.790 billion.

USDA on Monday dropped its estimate for U.S. corn good-to-excellent condition rating to 40 percent from the previous 48 percent. Traders expect USDA to show a similar decline in updated weekly crop progress data this Monday, including a decline in soybean conditions.

The worst drought in a quarter century tightened its grip on the Midwestern United States over the past week, a report from climate experts said Thursday.

Nearly two-thirds of the nine-state Midwest region was in some stage of drought in the week ended July 10, up from just over 50 percent a week earlier, according to the Drought Monitor, a weekly report on drought throughout the country compiled by U.S. climate experts.

A third of the region was in severe to exceptional drought, up from about a quarter of the region a week earlier, it said.

Well, it was reported via WUBA's last year that the NHC was running missions on these storms going nowhere because they wanted to gather data on how storms weaken. For amateurs like us, these storms are something to be awed by--and learn from as well. You never know everything ... right?

Not just "hot in the desert in summer", but "hotter than ever in the desert in summer". And while there's "hardly a storm anywhere", there have already been four on the Atlantic side earlier than ever, and a bunch of strong ones on the Pacific side. Not to mention unprecedented rainfall in various places, unholy heat in others, record-breaking fires in still others, and just general massive meteorological mayhem everywhere.

Sigh, indeed... ;-)
*Sigh* on behalf of balance (Yes, to whomever criticized me recently for using that word, I mean balance, not harmony.) - balance in Nature and balance in blogging.

As an example of balance, DocM acknowledges, and has for quite a while in his posts, the difference between "ever" and "observed" when he states, "The previous U.S. record high minimum temperature may be a 103F (39.C) observed in Death Valley, California in 1970. Higher record high minimums were set there in the early 20th Century, but the quality of the data is suspect." He also notes potential that this new record is not true. Would be interesting to know why the early 20th century data is suspect, when the high temp of 134F July 10, 1913 apparently stands as the highest temp there "in recorded history."

Great alliteration with "meteorological mayhem." In case you're going to use it again, here or on other forums where you post, imo this phrase has more impact if you drop "general" and "massive" from it.
Quoting JeffMasters:


This 110F low temperature in 1918 is disputed by weather records researcher Maximiliano Herrera, who says the temperature that night was not monitored and passed from 60F to 110F then to 60F again.

Jeff Masters
Thanks for clarifying that when you responded to skook posting at comment 247 the NWS Las Vegas statement calling July 12th the "second warmest" high low. I see you also modified your original blog post to reflect this. Took what's quoted above from your original statement before your modification. Will be interesting to see if NWS changes their tune or sticks with what's on the books.

Not that (edit) this record discussion is that important in the overall scheme of things...

Personally have 6.4" this month. Other areas in SE TX as much as 15". Ground is now saturated compared to last year at this time where everything was dead and ground had gaping holes in it and hard as a brick and trees dying.

Now the question is will the rains continue this summer and then have a hurricane come blowing in blowing all the trees down that are still dead and still brittle in places with the saturated ground.....recipe for mass defoliation of trees would be epic.

Anyone know how you can find the standard deviations for a weather measurement(humidity, PWAT, pressure) etc?

I know they are sometimes mentioned in forecast discussions, but does anywhere have them that you can look at?
I want to see what the standard devs are in GA.

Quoting FLWeatherFreak91:
Uh no... when the local weather service mentions a possibility of severe weather, it trumps the SPC.

If you haven't realized it yet, the SPC HATES Florida weather and is very hesitant to mention it at all. Florida weather is so unpredictable that trying to forecast it will ruin their precious accuracy.

The SPC does not forecast localized or unorganized severe weather espisodes, that is the responsibility of the local WFOs. The SPCs responsibility is organized severe weather that can be forecasted/monitored by looking at larger-scale features. Similar situation all along the gulf coast in summer - several days will have pop-up thunderstorms with multiple warnings, but few MDs and rarely watches.

Did you mean quiet or quite......if ElNino kicks in the late part of the season should be quieter. Remember massive flood damage was caused by TS Debbie in northern Florida. However if condictions remain neutral, that sometimes means more land falling storms for the USA.

2012-07-16 14:13 Geomagnetic Storm Winding Down

The ongoing geomagnetic storm is finally showing signs of weakening. G2 (Moderate) levels were observed during the event, but recent periods have been below the G1 (Minor) level. No further significant activity has occured, and while Region 1520 has become less of a threat, it still has the potential for further activity. Stay tuned for updates.

Hey, Sheri. It takes a while to get all the different bipolar relationships [pun intended lol] sorted out... I'm going to have to go back and do some reading on the NAO, because I know I know how it works, but I don't remember what I know I know... lol

This season is more of a cliffhanger to me than last year. I really don't know what to expect now. The part I was confident about has pretty much happened... now I'm waiting to see if we will get el nino conditions strong enough, soon enough to nip the height of the ATL season in the bud.

Either way I think we can expect some further storm formation before the month is out, and at least average storm formation during August. The key this year, IMO, is not so much how many or even when, as WHERE.

El Nino or no El Nini. if one has to to look at the global temperature, it appears that the central pacific has cooled considerably.and even the region off the peruvian coast has shown a drop in temperature. now there are area in the GOMEX and northwester carbbean where the sst are equal or higher than the eastern pacific. this i belive has put the break on the brake on the onset of El Nino.which is now allowing the sst in tropical atlantic to continue to warm thereby increasing the chances of an above average season. at the moment the area from the lesser antilles to the coast of Africa is under very dry and stable airmass which will preclude any tropical development in the near future.

There is a lot of really complex steering going on today, especially in the upper levels. The W coast sea breeze has formed, but will probably get stuck in its current position as a SE flow has pushed up against it already. With an upper level trough in place, expect all sea breeze activity to strengthen quickly.


There's no SE wind here. All the wind obs across E C FL are S or SSW. This favors eastern FL for thunderstorms to pile up and sit while dropping several inches of rain.
