Tropical Heat and Flooding Rains Return Later This Week"Deep
summer is when laziness finds respectability" wrote author and
philosopher Sam Keen. I'd add my own deep thoughts if I just had the
energy to get off the couch. Maybe
tomorrow.
During
an average summer (ha!) the atmosphere begins to stabilize in August.
Longer nights cool the Earth's surface, resulting in fewer instability
T-storms than June or July. In theory. On paper.
Not this year.
Minnesota is precariously perched on the northern fringe of a sprawling
heat bubble. Storms rippling along the U.S./Canada border yank some of
this drippy, super-heated air north, resulting in spasms of heavy
showers and T-storms.
According to NOAA last month was the 8th
wettest July, statewide, since 1873. Many towns saw 2 to 3 times their
normal rainfall last month.
Models print out another 1-2 inches of
rain for the metro this week; some 3-5 inch totals possible over parts
of central Minnesota by
Friday. The metro area may top 90F
Wednesday and
Thursday before a wind shift to the northwest cools us off again by next weekend.
This summer, when in doubt, just predict rain.

Another Heat Spike.
Models are suggesting a heat index in excess of 100F in the Twin Cities
Thursday, largely the result of predicted dew points close to 80F.
Relief comes in the form of heavy T-storms Thursday night (capable of
flash flooding in some areas), followed by a cooling north to northwest
breeze Friday and Saturday, dropping temperatures and humidity levels
back down to tolerable levels. Source: Aeris Enterprise.
Extreme Rains Central Minnesota?
The 12z GFS run predicted a bullseye of extreme rains over central
MInnesota, from near Alexandria to St. Cloud, with amounts in excess of
5-7" by Friday morning. Not buying it yet, but it's a data point - with
dew points in the 70s to near 80F and a surge of moisture from the
southwestern USA, courtesy of the soggy remains of Tropical Storm Javier
in the Pacific, I could see extreme amounts north of the Twin Cities
Thursday night. Source: WeatherBell.
Heaviest Rains North of MSP.
Model ensembles show 1-2" of rain for the Twin Cities (last night's 00z
run prints out 1.77" for MSP by Friday morning). But closer to Brainerd
amounts approach 4"; more than a month's worth of rain. Falling on
waterlogged, saturated soil from extreme rains a couple weeks ago I
could see more serious flooding for some areas of central Minnesota and
the Brainerd Lakes.
ECMWF Numbers.
European guidance isn't as extreme as the GFS predictions, but the
"Euro" still prints out 2-4" amounts for much of central Minnesota by
Friday morning. Source: WeatherBell.
Confirming the Obvious.
Yes, July was wet - averaged over the entire state it was the 8th
wettest since 1873, if anyone asks. More like two Junes in a row this
year. Source: MN Climate Office and AerisWeather.
Weekend Cool-Down; Another Hot Jab Next Week.
The Dog Days aren't going to fade anytime soon; no fast-forward into a

Aeris Weather Briefing: Monday, August 8
th, 2016
- Dangerous
– potentially historic – heavy rain and flooding will continue across
parts of the Gulf Coast as a slow moving disturbance works west this
week.
- Totals of 3-6” have already been reported in parts of
Florida through the weekend, and totals could top 8” from Louisiana to
northern Florida as we head into next weekend. Places that will see
heavy rain over the next several days will include Tampa, Tallahassee, Pensacola, Mobile and New Orleans.
- Numerous
roads will likely be impacted as we go through the week, with road
closures possible. Already some road closures have been reported in
Taylor County, FL Monday morning.
Radar As Of 9 AM ET Monday. Heavy rain is falling once again across parts of Florida this morning. In the
8 AM ET
hour, Clearwater, FL reported 0.66” of rain, indicative of the heavy
rain associated with these storms that will be likely over the next few
days.
Past 72 Hour Precipitation.
Already rain totals have been adding up throughout the weekend across
parts of west central Florida, with totals topping 3-5” in spots. A
CoCoRaHS observer near White Springs, FL reported 4.86” from
Sunday into early
Monday morning, and 5.88” fell at the Perry airport. Meanwhile, NWS radar has estimated that 10”+ of rain has fallen offshore.
Additional Rain Through Friday.
We will continue to see heavy rain along the Gulf Coast as we head
through the work week. The heaviest over the next couple days will be
across parts of western and northern Florida, including the Big Bend
region. The disturbance responsible for this heavy rain will slowly move
west throughout the week, focusing the heaviest rain toward the Emerald
Coast of Florida, as well as coastal Alabama, Mississippi and Louisiana
by mid to late week. This heavy rain has the potential to cause major
flooding across the region, and road closures will be likely.
Forecast Rain Into The Weekend:
Tampa, FL: 2-5”
Tallahassee, FL: 7-9”
Pensacola, FL: 9-12”
Mobile, AL: 6-8”
New Orleans, LA: 4-8”
Flood Watches In Effect. Flood Watches are in effect for parts of northern and west central Florida, including the Big Bend region into
Tuesday
morning for an additional 3-8” of rain on top of 2-8” already in spots.
Flood Watches will likely be extended westward as we head into later
this week as the heaviest of the rain slowly moves in that direction.
Flash
Flood Watches are also in effect for parts of northeast Georgia, North
Carolina and upstate South Carolina through this evening, where heavy
downpours could quickly lead to 1-3” of rain across the region. Some
local 4-6” totals are possible.
Flooding Concerns Through Wednesday.
The Weather Prediction Center has outlined areas across parts of the
Southeast and Gulf Coast over the next three days where the best
opportunity of flash flooding will occur with heavy rain falling and
already saturated ground. The potential of flooding will extend
throughout the entire week across this region.
Summary. Heavy
rain will continue across parts of the Gulf Coast as we head through
the work week due to a slow moving disturbance. Already 3-6” of rain has
fallen this weekend across parts of Florida, and areas from New Orleans
into northern Florida could easily end up with at least 8” of rain
through the end of this week. This heavy rain will likely cause flooding
and road issues across the region. Facilities across these areas that
normally experience problems during flash flood scenarios should
continue to be on alert for issues over the next few days.

Warmer Than Average July, Year To Date Third Warmest For Lower 48 States. Details via
NOAA: "
July’s
reputation for sizzle didn’t disappoint, bringing record warm
temperatures to Florida and New Mexico and much above-average
temperatures across the South, the East Coast and Alaska. The average
July temperature for the contiguous U.S. was 75.3 degrees F, making it
the 14th warmest July on record, according to scientists from NOAA’s
National Centers for Environmental Information. July precipitation
averaged 2.87 inches (0.40 inch above average). From January through
July, the average temperature for the Lower 48 states ranked as the
third warmest on record at 54.3 degrees F, 3.0 degrees above average.

Billion Dollar Weather Disasters Since 1980. Dollar-adjusted damage from tropicals systems exceed all other forms of severe weather combined, according to data from
NOAA NCDC: "
The
distribution of damage from U.S. Billion-dollar disaster events across
the 1980-2016 preriod of record (as of July 2016) is dominated by
tropical cyclone losses. From 1980-2016, land falling tropical cyclones
have caused the most damage ($547 billion, CPI-adjusted) and also have
the highest average event cost ($16.1 billion per event, CPI-adjusted).
Drought ($218 billion, CPI-adjusted), severe storms ($175 billion,
CPI-adjusted) and inland flooding ($97 billion, CPI-adjusted) have also
caused considerable damage based on the list of billion-dollar events.
It is of note that severe storms are responsible for the highest number
of billion-dollar disaster events (81) yet the average event cost is
among the lowest ($2.2 billion, CPI-adjusted) but still substantial.
Tropical cyclones and drought represent the second and third most
frequent event types (34 and 23), respectively..."
An Eye-Opening Flight Over California's Dying Forests. Here's an excerpt of a sobering and equally eye-opening article at
The San Francisco Chronicle: "...
The
four crew members were halfway through two weeks of flights over
landscapes shifting ominously from green to brown, and already they’d
begun to draw their conclusion: The mind-boggling number of trees that
have died in California due to drought — an estimated 66 million over
five years — is only the beginning. The death toll will probably rise by
tens of millions of trees, even if heavier rains come this year, said
Greg Asner, head of the team from Carnegie Institution for Science in
Washington, D.C. Using technology that has diagnosed problems in the
Amazon rain forest and the jungles of Borneo, the researchers are
learning that California’s unprecedented tree die-off is moving well
beyond its origins in the southern Sierra Nevada and along parts of the
southern coast..."

Louisiana Politicians Go To Court Blaming Big Oil for Coastal Ruin. Here's the intro to an explainer at The Associated Press: "The
oil industry has left a big footprint along the Gulf Coast, where a
Delaware-sized stretch of Louisiana has disappeared. But few politicians
would blame Big Oil for ecosystem abuse in a state where the industry
employs up to 300,000 people and injects $73 billion into the economy.
Until now. Following the lead of Gov. John Bel Edwards, Louisiana
political orthodoxy is being turned upside-down as prominent leaders of
both parties join lawsuits seeking billions of dollars for environmental
improvement projects..."

To Clean Up An Oil Spill, Light a Fire Tornado. Here's an excerpt of a D-Brief at
Discover: "...
These
fire whirls could also potentially be used in combustion power plants
as a way to generate power with less waste. “Fire whirls are more
efficient than other forms of combustion because they produce
drastically increased heating to the surface of fuels, allowing them to
burn faster and more completely. In our experiments over water, we’ve
seen how the circulation fire whirls generate also helps to pull in
fuels. If we can achieve a state akin to the blue whirl at larger scale,
we can further reduce airborne emissions for a much cleaner means of
spill cleanup,” says Michael Gollner, a co-author of the paper in a press release..."

The Making of a Fractivist. When it's your home, your kid's school that's being impacted, suddenly things get personal, according to a story at

She
read health studies from around the country that showed higher asthma
rates near fracking sites, air quality studies that showed higher levels
of the carcinogen benzene near fracking sites, and water studies that
showed that leaking containment ponds used by energy development
companies tainted drinking water sources. Not to mention her growing
awareness that climate change science pointed to a growing problem that
was bound to mess with her kids’ future. For Pidanick, who lives in a
covenant-controlled community that determines what color she can paint
her house, whether she can have a basketball hoop on her garage, or how
long she can park a car on the street, it’s galling to know that she
can’t have a say in whether or not industrial activity can take place

Ending $4 Billion U.S. Oil Subsidy Seen Having Minimal Impact. Bloomberg reports: "Eliminating
$4 billion of petroleum subsidies in the U.S. would have only a minor
affect on oil production and demand and boost the country’s influence in
advocating global climate change action, according to a report
for the Council on Foreign Relations. Withdrawing oil-drilling
subsidies could cut domestic production by 5 percent by 2030, which
could increase international oil prices by just 1 percent, Gilbert
Metcalf, a professor of economics at Tufts University, said in the
report. Local natural gas prices could rise as much as 10 percent, while
both production and consumption would probably fall as much as 4
percent, according to the report..."
Against "Sustainability". Here's an excerpt of an Op-Ed at
The New York Times: "...
When
we talk about sustainability, then, what is it that we hope to sustain?
We certainly do not sustain nature “in itself.” Rather, we sustain
nature as we humans prefer it. More precisely, we preserve the resources
needed for human consumption, whether that means energy consumption or
aesthetic consumption. In one sense, we preserve nature for industry.
The human activity that has produced these environmental shifts is not
isolated to one practice or one epoch, say, the consumption of carbon in
the 20th century — though it may be accelerated by this. As Kolbert
argues, the rise of Homo sapiens fundamentally altered the planetary
ecosystem long before the invention of writing, the birth of René
Descartes, or the first diesel pump..."

included as a target for global development goals adopted by world
leaders in 2015..."

Do You Suffer From "Library Anxiety?" Wait, what's a library? Here's an excerpt from
Atlas Obscura: "...
Library
anxiety is real. The phenomenon, which involves feeling intimidated,
embarrassed, and overwhelmed by libraries and librarians, was first
identified by Constance A. Mellon in 1986. Her paper, "Library Anxiety: A Grounded Theory and Its Development,"

anxiety because they believe their research skills are inadequate, which
makes them feel ashamed and unwilling to talk to the very librarians
who might be able to ease their worries...."

The Weaker Sex. An article in The Economist
argues that blue-collar men living in rich countries are in trouble -
will they be able to adapt to sweeping changes? Here's an excerpt: "...One group in particular is suffering (see article).
Poorly educated men in rich countries have had difficulty coping with
the enormous changes in the labour market and the home over the past
half-century. As technology and trade have devalued brawn, less-educated
men have struggled to find a role in the workplace. Women, on the other
hand, are surging into expanding sectors such as health care and
education, helped by their superior skills. As education has become more
important, boys have also fallen behind girls in school (except at the
very top). Men who lose jobs in manufacturing often never work again.
And men without work find it hard to attract a permanent mate. The
result, for low-skilled men, is a poisonous combination of no job, no
family and no prospects..." (Illustration credit: Jon Berkeley).
New Study Finds That Men Are Often Their Own Favorite Experts On Any Given Subject. Yes, but it anyone really surprised by this? Here's an excerpt from The Washington Post: "A fascinating new working paper finds
that men are far more likely than women to back up their arguments with
appeals to a higher authority: themselves. When an academic writes a
research paper, it is common practice to give citations for various
facts and assertions. It is not enough, for instance, to simply assert
that "the global rise of the hyperdiverse ant genus Pheidole is an evolutionary epic with many subplots." You need to cite biologist Corrie S. Moreau's 2008 paper on "Unraveling the evolutionary history of the hyperdiverse ant genus Pheidole" to make that argument..."

Climate Change Warning Signs Getting Stronger. Here's an excerpt from
The Toledo Blade: "...
The
new U.S. EPA report said the incidence of Lyme disease has doubled in
the United States since 1991 as warmer temperatures allow more ticks to
spread the disease. While New England continues to have the heaviest
infestation, the Great Lakes states of Pennsylvania, Wisconsin, and
Minnesota have also had large increases, the report said. The report
showed the ragweed pollen season being extended as many as 18 days in
Minnesota, 21 days in North Dakota, and as many as 25 days in parts of
Canada and Missouri. It did not have information on the Zika virus, and
said the jury’s still out on any correlation between climate change and
West Nile virus. “Those are public health costs. Those cost money,” Mr.
Szollosi said. “Those cause people to be off work. Those are not

Can We Help The Losers in Climate Change?
Communities and industries will be transformed - what can we do to make
these inevitable changes more tolerable - how best to adapt? Here's an
excerpt from
MIT Technology Review: "...
In
many ways, the disappearance of the coal economy is a harbinger of
major transformations that climate change will bring about in other
regions and other sectors. Industries from agriculture to real estate
are likely to be devastated by global warming. While the effects on
those sectors will look very different from the impact on the coal
industry, the results will be similar: economic harm to large regions of
the country. And yet little thought has been given to comprehensive,
fair, effective strategies to manage those disruptions. In that sense
the demise of the coal industry in West Virginia and Kentucky is just a
trial run for much larger challenges ahead..."

Why The Rio Olympics and Leonardo DiCaprio Get Your Attention on Climate Change. Dr. Marshall Shepherd explains at
Forbes: "
If
you watched the Opening Ceremony of the Rio Olympics Friday evening,
social media was buzzing about the bold inclusion of a segment on
climate change. The segment highlighted the perils of sea level rise on
vulnerable nations and cities and also showed Ed Hawkins’ compelling visual spiral indicating global warming. I
also noticed more activity on my social media platforms from people
that normally do not talk about the topic. The overwhelming comments
where things like “wow, that was a wake up call” or “that really
stimulated a conversation with my kids.” On the same day, I read a study
showing that Leonardo di Caprio’s speech about climate change at the Oscars strongly
resonated with the public. This convergence made me ponder why the “Rio
Olympic Effect” and “the DiCaprio Effect” resonates with the public
even though scientists have been warning of many of these effects for
decades..."

Scientists Warn World Will Miss Key Climate Target. The warming appears to be accelerating, with or without an El Nino turbo-boost. Here's an excerpt from
The Guardian: "...
However, figures – based on Met Office data – prepared by meteorologist Ed Hawkins of Reading University
show that average global temperatures were already more than 1C above
pre-industrial levels for every month except one over the past year and peaked at +1.38C in February and March. Keeping
within the 1.5C limit will be extremely difficult, say scientists,
given these rises. These alarming figures will form the backdrop to the
Intergovernmental Panel on Climate Change talks in Geneva this month,
when scientists will start to outline ways to implement the climate
goals set in Paris. Dates for abandoning all coal-burning power stations
and halting the use of combustion engines across the globe – possibly
within 15 years – are likely to be set..."
