87 F. high in the Twin Cities Monday.
84 F. average high on July 7.
91 F. high on July 7, 2013.
.37" rain fell yesterday at MSP International Airport.
July 7, 1974:
Heat wave with the Twin Cities reaching 101, warmest in 26 years. 2002
three-day deluge ends in central Minnesota with 10 inches in northern
Kanabec county and 9.5 inches in southwest Aitkin County.
Atmospheric Lag
June
21 is the Summer Solstice, when the sun is highest in the sky - the
best day of the year to catch a debilitating sunburn. Yet the hottest
weather of summer normally comes 2-3 weeks later. Why the lag? Just like
a pot water on a hot stove takes a few minutes to come to a boil, so it
is with our climate system. Land warms faster than water, which means
Minnesota's hottest weather arrives in mid July most years.
We've seen glimpses, snapshots of heat, but no long-lasting heat waves to speak of, which is just fine with most folks.
Just
when I thought 2014 couldn't get any goofier, the models I'm staring at
next for early next week look like late September or early October. No,
we shouldn't be tracking Alberta Clippers and families of Canadian cool
fronts during prime time summertime.
Whether its a symptom of El
Nino or evidence of a confused (or "drunk") jet stream buckling
unusually far south for July, expect a cool bias into mid-month.
Clouds
linger today; dew points dropping into the 40s Wednesday will leave us
all breathing easier. T-storms Friday give way to comfortable sunshine
Saturday; highs in the 80s. A more vigorous, almost autumn-like airmass
arrives early next week, sparking T-storms Sunday afternoon and a
whisper of wind chill by Monday morning, a day we should be experiencing
some of the hottest weather of the year.
Sweatshirt weather on July 14.

Monday Severe Storm Reports.
1 to 1.5" diameter hail was reported over the south metro yesterday
from Shakopee to Burnsville and Bloomington; wind gusts as high as 50-60
mph reported from Cologne to Hastings. 1.3" of rain was reported near
River Falls, Wisconsin. NOAA has a complete rundown on severe storm
reports
here. The local MPX Weather Service office has an
interactive map.
Monday Doppler Radar Rainfall Estimates.
Twin Cities NWS Doppler based in Chanhassen estimated some 2" amounts
yesterday near Menomonie; some 1" amounts near Bloomington from the
fast-moving squall line.
More Unusual Swings.
After cooling off by midweek with dew points dropping into the upper
40s and low 50s we warm up again by the weekend (low to mid 80s possible
both days). This next push of warmer air sparks a few showers and
T-storms Thursday night into Friday. Saturday appears to be the nicer,
drier day of the weekend. The approach of an airmass that would be right
at home on September 30 sparks T-storms during the PM hours Sunday; by
Monday and Tuesday temperatures may not climb out of the 60s. Unusual,
considering early and mid July usually brings the hottest weather of the
year. Source: Weatherspark.
7-Day Rainfall.
Heaviest rains fall from the Midwest into the Ohio Valley and Carolinas
thru Tuesday of next week; some 2-4" amounts in downpours over Florida.
Monsoon T-storms drop some badly needed rain from Arizona into

Super Typhoon Heading for Japan is a "Once in a Decade" Storm, Says Forecasters.
Neoguri may be the most intense typhoon (same thing as hurricane) to
impact Japan during the month of July. Here's an excerpt from a story
about "Neoguri" from
The South China Morning Post: "
Japan's
weather forecasters today described Super Typhoon Neoguri, which is
barrelling towards the country, as a 'once in decades storm'. With winds
already at a sustained 180km/h and gusting up to 250km/h, the typhoon
is expected to gain power before it hits the southern Okinawa island
chain before making landfull on the country's westernmost island of
Kyushu - home to two nuclear plants. Japan's Meteorological Agency
predicted it would grow into an "extremely intense" storm by Tuesday..."

A Scary Super Typhoon Is Bearing Down on Japan, and It's Nuclear Plants.
Neoguri may still hit as a Category 1-2 strength typhoon, capable of
significant storm surge damage. In light of the tragedy of Fukushima
Chris Mooney at
Mother Jones examines the safety of two plants in its potential path; here's an excerpt: "...
According to reporting by Reuters,
there are two nuclear plants on the island. A company spokeswoman for
Kyushu Electric Power Co. told the news agency that it "has plans in
place throughout the year to protect the plants from severe weather."
Will that be good enough? According to Edwin Lyman,
senior scientist in the global security program at the Union of
Concerned Scientists, the good news overall is that Japan's nuclear
plants are currently shut down, awaiting permission to restart as they
institute stronger safety protections, including the construction of
higher seawalls. A shut-down plant is still not without risks, because
"you still have to provide cooling for the fuel," says Lyman..."
Understandable Paranoia. Science writer Greg Laden has more details on the two Japanese reactors in the potential path of Super Typhoon Neoguri at

Warm Waters Around Florida Inviting to Hurricanes.
The warmer (and deeper) the water, the greater the potential for
hurricane intensification, all other things being equal. Here's a clip
from a story at
The St. Augustine Record: "...
In
August, the surface waters around Florida, from the Gulf of Mexico to
the Straits of Florida to the close-in waters of the Atlantic Ocean,
average a nice, warm, inviting 84 degrees Fahrenheit. Tropical storms
need to feed on surface water that’s about 78 degrees. If deep water is
cooler, as the storm brings it to the surface, the hurricane’s not
getting enough hot water — high octane fuel — and it weakens..." (Image credit: NASA).
How IBM Is Using Big Data To Fix Beijing's Pollution Crisis.
Quartz
has a fascinating article about how China is trying to use Big Blue's
ultra-high-resolution computer modeling to track down the source of some
of the worst pollution; here's a clip: "...
IBM
plans to improve the quality of data by installing its latest
generation of optical sensors, incorporating meteorological satellite
data and running that through its artificial-intelligence
computing system (a.k.a. Watson, that computer that trounced humans on Jeopardy).
The visual maps it generates will identify the source and dispersal
pattern of pollutants across Beijing with a street-level degree of
detail 72 hours in advance..."

The First Conscious Machines Will Probably Be On Wall Street. When in doubt follow the money. Here's an excerpt of a fascinating, if not altogether reassuring, story from
The Mitrailleuse: "...
Even
today we see supercomputers owned by financial institutions, making
trading decisions on behalf of the companies that own them. These are
specialized machines that do something that produces similar results to
cognition. The fact that they are specialized thinking machines might
lead one to believe that this precludes them from consciousness. I think
the opposite is true; human beings are not generalized computing
organisms. Humans, just like the machines in question, are not general
purpose beings, but highly selective imitation devices with an innate
dedicated language system..."
Barry Gibb: The Last Brother.
Here is a sad and poignant story about Barry Gibb, the last remaining
member of the Bee Gees, an excerpt from an in-depth interview at
RollingStone.com: "...
They're
the only group in history to have written, recorded and produced six
consecutive Number One hits. "We weren't on the charts," Maurice once
boasted, "we were the charts." And then, just like that, they weren't.
America decided that disco sucked, and the Gibb brothers went from icons
to punch lines overnight. Andy passed away, then Maurice. Now that
Robin was gone, Barry was the only one left..."

Is A Wedding Day Tornado Good Luck? Because nothing says I love you better than holding hands in front of an EF-2 tornado. Here's more from

Climate Stories...
Study Finds "Extreme" Climate Change in National Parks. National Geographic has the details; here's the introduction: "
Many
national parks in the United States have already experienced "extreme"
climate change over the past few decades, and the trend is likely to
accelerate unless bold steps are taken, government scientists warn in a
new study. Those changes are likely to disrupt visitor experiences and
damage natural and cultural resources. "This report shows that climate
change continues to be the most far-reaching and consequential challenge
ever faced by our national parks," National Park Service Director
Jonathan B. Jarvis said in a statement..."

Picking Lesser of Two Climate Evils.
Is natural gas, a so-called "bridge fuel" with half the greenhouse gas
emissions, really better than coal over the long term, when methane
leakage is included in the calculations? Justin Gillis has an
interesting article at
The New York Times; here's an excerpt: "...
One
of the biggest fights involves how much effort to put into stopping
leaks of methane gas into the atmosphere. It may sound like an obscure
topic, but the leaks could have a great effect on the climate that
people living today experience. This issue has grown in importance with
the release of President Obama’s new climate plan.
It calls for greater use of natural gas, which consists mostly of
methane. Among a few academics and on the far left of the environmental
movement, cries are going up that the president is about to lock America
into a supposed solution to climate change that will be worse than
burning coal..."
File photo credit: "A
fracking operation, also known as hydraulic fracturing, in Washington,
Penn., June 20, 2012. President Barack Obama's new climate plan calls

U.S. House Candidate Makes Climate Action a Campaign Centerpiece.
Registered voters are 2.5 times more likely to vote for a congressional
or presidential candidate who supports action to reduce global warming.
Further, registered voters are 3 times more likely to vote
against a candidate who opposes action to reduce global warming? That's an excerpt of a story by Peter Sinclair at
Climate Denial Crock of the Week: "
Michigan House District 11 Candidate Nancy Skinner
is making climate change a centerpiece of her campaign, going into
next month’s primary, and has come out swinging with the piece you see
above. Last week I posted a bit of distilled climate paranoia, in a
video from a Louisiana congressional primary, where Sara Pailin clone Lenar Whitney laid out the complete conspiracist’s looniest fantasy of
climate science as a global plot. The piece has appeared in a lot of
places, and I think its an example of looney climate denial having jumped the shark in the American mind..."
Rolling Coal. Yes,
for a mere $500 you can trick your truck into burning more gas and
putting out more black exhaust, annoying any Prius owners in your midst.
Because there's nothing funnier than being smelly, dirty and wasteful.
Here's a clip from
Slate: "
Prius
Repellent” is a perfect introduction to one of the Obama era’s great
conservative subcultures: the men and women who “roll coal.” For as
little as $500, anyone with a diesel truck and a dream can install a smoke stack
and the equipment that lets a driver “trick the engine” into needing
more fuel. The result is a burst of black smoke that doubles as a
political or cultural statement—a protest against the EPA, a ritual
shaming of hybrid “rice burners,” and a stellar source of truck memes. The “Prius repellent” decal is easy to find on truck fan sites, as are memes of single or double stack trucks humiliating the drivers of smaller cars..."
