Amazing Sunday - A 500-Year Flood for Louisiana
"The red-winged blackbirds in my yard usually fly south in early August" Pete explained at Breezy Point. "This year they left in July. What does it mean?" I shrugged and shook my head. "Too wet?"
Over 4 inches of rain has soaked the metro so far in August; some Minnesota towns have already picked up 2 month's worth of rain this month.
"Phenology" is the study of seasonal changes in animal and plant behavior. But animals and plants react to previous weather patterns - rather than predicting what's to come.
My winter outlook: "changeable". Take it to the bank.
While we savor an amazing Sunday with more sun, lighter winds and a lack of afternoon instability showers, residents of Louisiana are under a State of Emergency; another stalled storm unloading 2 FOOT rainfall amounts and historic flooding. By my count it's the 8th 500-year flood to strike the USA since May of 2015. Probably nothing to worry about.
More T-storms ignite Monday night and Tuesday with highs climbing through the 80s this week. Not as beastly-hot (or wet) as last week, though.
A hefty cool front may be jacket-worthy up north next weekend but summer warmth spills into September.
- A State of Emergency for the state of Louisiana has been declared due to ongoing historic flooding.
- Numerous areas across parts of southeast Louisiana and southern Mississippi have seen over 10” of rain since Thursday.
- Parts of southern Louisiana and into west Texas could see an additional 4-7”+ of rain throughout the day today, including Baton Rouge, Lafayette, Alexandria and Lake Charles (LA) as well as Beaumont (TX).
The Baton Rouge newspaper The Advocate has put together an interactive map of areas hit the hardest in the region by flooding: http://www.theadvocate.com/
Summary. Major flash flooding continues across parts of the lower Mississippi Valley today, with another 4-7”+ of rain expected. That’s on top of 10-15”+ in some of these areas. Numerous roads have been reported underwater, including parts of I-10 and I-55. Facilities across these areas that normally experience problems during flood scenarios should continue to be on alert for issues over the next few days.

NOAA Maintains La Nina Forecast for Fall or Winter. The observed cooling of Pacific ocean water has been tame, the forecast of official La Nina conditions pushed back, according to Reuters: "A U.S. government weather forecaster on Thursday reduced its outlook that La Nina conditions would develop in next few months but said it still expected the weather phenomenon to occur this fall or winter. The National Weather Service's Climate Prediction Center said in its monthly forecast that La Nina was "slightly favored" to develop through October. That was a small change from July, when it stated the conditions were "favored" to occur. The agency maintained its forecast of a 55 percent to 60 percent chance that La Nina would develop during the fall and winter of 2016/17..."

Surveyed Scientists Debunk Chemtrails Conspiracy Theory. Here's the intro to a story at UCI News: "The world’s leading atmospheric scientists overwhelmingly deny the existence of a secret, elite-driven plot to release harmful chemicals into the air from high-flying aircraft, according to the first peer-reviewed journal paper to address the “chemtrails” conspiracy theory. Researchers from the University of California, Irvine, the Carnegie Institution for Science and the nonprofit Near Zero organization asked 77 atmospheric chemists and geochemists if they had come across evidence of such a large-scale spraying program, and 76 responded that they had not. The survey results were published Wednesday in Environmental Research Letters. Heat from aircraft engines produces condensation trails that can be clearly seen from the ground. A small but vocal segment of the population firmly believes that these are composed not merely of condensed water vapor but of chemicals and elements such as strontium, barium and aluminum that powerful, high-level entities have been intentionally and covertly releasing into the atmosphere for decades..."

A Court Ruling That Could Save the Planet. Bloomberg View has the story: "A federal court this week upheld the approach that the government uses to calculate the social cost of carbon when it issues regulations -- and not just the cost imposed on Americans, but on people worldwide. It’s technical stuff, but also one of the most important climate change rulings ever. The social cost of carbon is meant to capture the economic damage of a ton of carbon emissions. The assumptions that go into the analysis, and the resulting number, matter a lot, because they play a key role in the cost-benefit analysis for countless regulations -- not only the Obama Administration’s Clean Power Plan, but also fuel economy rules for automobiles and trucks and energy efficiency rules for appliances, including refrigerators, microwave ovens, clothes washers, small motors, and clothes driers..."

Guest Post: Piecing Together the Arctic's Sea Ice History Back to 1850. Here's an excerpt of an interesting post at Carbon Brief: "...Most fundamentally of all, the new dataset allows us to answer the three questions we posed at the beginning of this article. First, there is no point in the past 150 years where sea ice extent is as small as it has been in recent years. Second, the rate of sea ice retreat in recent years is also unprecedented in the historical record. And, third, the natural fluctuations in sea ice over multiple decades are generally smaller than the year-to-year variability..."

As Earth Swelters, Global Warming Target In Danger of Being Missed. Here's the intro to an update at Reuters: "The Earth is so hot this year that a limit for global warming agreed by world leaders at a climate summit in Paris just a few months ago is in danger of being breached. In December, almost 200 nations agreed a radical shift away from fossil fuels with a goal of limiting a rise in average global temperatures to well below 2 degrees Celsius (3.6 Fahrenheit) above pre-industrial times while "pursuing efforts" for 1.5C (2.7F). But 2016 is on track to be the hottest year on record, also buoyed by a natural El Nino event warming the Pacific, according to the U.N.'s World Meteorological Organization. The first six months were a sweltering 1.3C above pre-industrial times..." (File photo: AP).
