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!

Quoting FLWeatherFreak91:
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.

The Joint Typhoon Warning Center (JTWC) has upgraded 08W to Tropical Storm Khanun, the seventh of the 2012 Pacific typhoon season. The system is expected to peak as a mid-grade tropical storm, and should rapidly weaken after 36 hours due to cooler Sea Surface Temperatures and increasing vertical wind shear.

Hi all.
The local weather said our storms would move W to East today.
But it looks like the steering is quite weak ATM. Storms arent moving much Down in SW Fl.

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.


SPC really drops the ball when it comes to FL's weather. Cold air moving in aloft on top of a tropical airmass means trouble here in FL. Infact it is already clouding up fast. I've had 7.88" of rain so far this month at my location and that's on top of the nearly 13" last month and 5" in May. I do think the main threat will be flooding of low lying areas as these thunderstorms are going to really pile up across eastern FL due to weak SSW stearing today.


It also looks as if this is trying to get a surface reflection under the ULL.

Member Since: Posts: Comments:
The SPC generally forecasts widespread severe wx events, which will likely not be the case in C/SW FL today. There will be strong storms with a possibility of scattered stong/severe storms north of the bay area. Doesn't mean that severe weather won't occur, just not on the scale they usually forecast for.

EDIT: As a side note just because that is the area they are predicting severe storms to form doesn't mean that's where they have to form. Heck even on a normal day a thunderstorm in FL can turn severe.

Generally speaking when the E. Pacific is active the Atlantic is generally quiet. Now, that's not written in stone, but like I said generally speaking. As far as the El Nino forecast goes for the Pacific, I'm not sure anyone knows where its headed at this point. It's been waffling around a bit lately.

So I think we're just about out of our drought now. 9.34" so far for July, drainage ditches are starting to stay full, and it's been raining an inch or more ever other day or so in the last week.




Weve had a heavy afternoon Tstorm at my house 7 days in a row now, but overall rain totals across the area are still pretty average for July(some are over)

The exceptions are ECentral and Central GA where the rain has been more sparse, which is a problem with the drought.
I would not be surprised to see the severe drought not expand, and possibly even shrink this week, and we have a 30-40% chance of rain each day indefinitely

Hey, Freak! Good to see u in the blog! I gotta admit it looks like ur area is going to get the best of the wx today... most looks like it's headed N of here.

IF it keeps cooling or stays cool, it means we go to the heart of the season with warm neutral conditions, which are not the best for a quiet season. [Correct me if I'm wrong, but I think 2005 was a warm neutral year...]. It doesn't guarantee a busy season, but it doesn't deter one, either. The bad thing about warm neutral seasons, IIRC, is they tend to have more storms form in the Car and near the western periphery of the ATL basin. That means fewer chances of recurvature without landfall...

But we shall see what we shall see..

I have dealt with way too much **** the last several weeks. The combination of work and family (you know what I'm talking about) has finally taken its toll on me. Yes, on me, the self-proclaimed logician. Dreadful, I know. But I realize I'm a person too. I can't always be an emotionless robot. I'm taking a temporary leave of absence from this blog, as I simply do not have the patience to deal with people right now. I don't know how long it will be. Maybe I'll rear in my head back in when Ernesto shows up. Or maybe I won't. I really don't know, and I honestly don't care. I will still be posting blog entries (just not here), so for those interested in them, or for those who still wish to contact me for any reason, feel free to use my email (verykoolguy2002 [at] gmail [dot] com). I will get back to you when I can. I feel like I'm falling into depression again, something I haven't dealt with in two years. But don't worry, I will persevere.

Adios you guys. It's been fun. I will miss this place. But I seriously need some time away from it. Peace and love.

Exactly. You can learn a lot from these "doomed" storms. For me it's been interesting to see each one form and the differences in formation, strengthening mechanisms, deterioration and environmental interaction. And the bonus? You can be pretty sure they aren't going to be wreaking much havoc to land. No flooding, no storm surges, no land slides, no death. They are powerful and beautiful and mostly benign (well, ignoring the shipping issues. ;))

There is specific definition of severe weather, and the Storm Prediction Center does not have FL in that kind of zone right now. You mean some heavy rain and thunder, which likely won't be severe.
Not to mention there were plenty of warnings during the past 2 weeks here, and I don't think the SPC highlighted us at all.

Recent cooling in the equatorial Pacific means that El Nino has briefly been delayed, but the overall trend is still towards the 0.5C threshold. The longer El Nino delays, the more favorable the Atlantic will be next month and in September.

Violent storm turns night into day over Washington- residents claim the ‘most intense’ lightning storm ever seen
Posted on July 15, 2012
Cisco Wilkinson of west Pasco took this photo at 4 a.m. Saturday. “It was so bright, I was temporarily blinded,” Wilkinson said. “It looks like it’s daytime.”
July 15, 2012 – WASHINGTON – There were a lot of tired people in the Tri-Cities on Saturday after an early morning electrical storm rattled homes and flashed bright lights through windows. The system that led to a severe thunderstorm warning from the National Weather Service also cooled down the Mid-Columbia after a string of 100-plus degree days. The light show and downpour didn’t appear to cause any significant damage, with police and fire officials surprised at how few calls were received. However, it might not be over, with the forecast calling for a slight chance of thunderstorms through the rest of the week as the temperatures heat up again. Those storms continue to bring the threat of lightning sparking wildfires. The thunder and lightning that moved through the area earlier Saturday seemed anything but normal to the dozens of residents who took to social media to describe the experience. Some referred to it on the Tri-City Herald’s Facebook page as “the best storm ever” or the “most intense” they’ve experienced in the Northwest. People awakened by the loud booms reported staying up through the early morning hours because they were fascinated by Mother Nature’s spectacular display, or simply realized that attempts at sleep were futile. A severe weather alert issued at 2:37 a.m. said two storms were located six miles southwest of Kennewick and moving north at 30 mph. Within minutes, the storms moved over the Tri-Cities and seemed to hunker down for almost three hours, with cloud-to-cloud lightning that often was so bright it appeared to be daytime. The National Weather Service’s warning described it as “a dangerous storm,” and told residents to prepare for damaging winds, destructive hail and deadly lightning that could strike the ground. People were instructed to seek shelter inside a strong building, but away from windows. The weather service took two calls from the public reporting hail the size of a quarter in Kennewick. Public reports of wind speeds in Kennewick ranged from gusts of 35 to 40 mph to gusts up to 60 mph that drove the rain and hail sideways. “I’m sure it’s been a blast for people to watch the lightning,” Brooks said. The weather service had been expecting the storms to form for a couple of days because of instability with a low-pressure system and warm temperatures, Brooks said. –News Tribune

Good morning!

Well, I have to say that the Kingfish Tournament was a little bit of hell for everyone yesterday. That tropical wave rolled in on us about 6:00 a.m. and turned the seas from 3-4 ft. to 10-12 in a number of minutes. Although I did catch a nice-sized barracuda (one of the competition fish), it wasn't enough to win anything. Still, a good time had by all.

Other than that, the sky has cleared up this morning with a nice breeze.

Have a great day, all!
