69 F. high in the
Twin Cities Thursday. The forecast of upper 70s was a bust. Repeated
waves of showers and T-storms kept us cooler than anticipated; we never
broke out into the sunny, warm sector for any length of time, which also
prevented the most extreme T-storms from firing near the metro area.
67 F. average high on May 8.
78 F. high on May 8, 2013.
.58" rain fell at KMSP yesterday.
Too Much Warning?
As
technology advances it brings up new opportunities and subsequent
challenges. The average national lead-time for tornadoes (from detection
to arrival) is 14 minutes, nationwide. Researchers are working on new
algorithms that may lengthen that lead time to 45 minutes within the
next 3 years. A major advance, right? Absolutely.
But anecdotal
evidence suggests that having more lead time allows people to make bad
choices: driving home from the office or picking the kids up at school -
all of which increase the risk of becoming a tornado statistic. An odd
conundrum.
Tornado season peaks in June here in Minnesota; yesterday was just the first warning shot across the bow.
Clouds
linger today, the best chance of showers north of the Twin Cities.
Fishing Opener starts out cool & dry, but showers push in by
afternoon - highs near 60F north to mid 60s metro area.
Take your
favorite mom to an early brunch Sunday; clouds thicken on Mother's Day
with another surge of rain, heavy at times, Sunday night into Monday.
Cool, Canadian exhaust on the backside of this next storm keeps highs in
the 50s to near 60F much of next week. Nights dip into the 35-43F
range, but no frost. No tornadoes either.
Hallelujah.
St. James Tornado Footage. Check out the
YouTube clip captured late this afternoon in the St. James area - that sure looks like a confirmed tornado on the ground to me. Credit: "
KDR
Media chaser, Kholby Martin documented a tornado in Saint James, MN
this evening. Tornado touched down just to the north of by ¼ of a mile
and crossed the road, tearing up the ground. It was roughly a couple
hundred yards wide yet not fully condensed."
Thursday Severe Storm Reports.
I counted at least 3 separate touchdowns Thursday in Minnesota,
although the tornadoes in St. James and Lake Crystal were from the same
rotating, parent supercell thunderstorm. The south metro got the worse
end of Thursday's squall lines - most of the hail reports from the line
that came through early in the day. Winds gusted to 60 mph, bringing
down tree limbs, causing sporadic power outages. We just got a taste -
in retrospect it could have been much worse. A lack of sunlight, and
subsequently cooler temperatures near the ground, prevented the
explosive instability that could have spun up large, damaging tornadoes.

What Is It Like To Experience A Tornado? Check out this remarkable
YouTube
security camera video from St. Luke United Methodist Church, where a
large tornado struck last week. My one take-away: that's some sturdy
playground furniture.
Edmond (Oklahoma) Tornado Sirens Can Talk.
Just wait until one gets hacked by an Internet-savvy prankster. But
overall this may not be a bad idea, go beyond a dumb-siren and have an
alerting system that provides site-specific details? Sounds like
progress to me, although I'll say it again, if you rely (only) on sirens
you're setting yourself and your family up for trouble. Here's a video
and excerpt from FOX25 in Oklahoma City: "...
Starting Wednesday, the
City of Edmond activated its new voice alert systems at both Mitch and
Hafer Parks. "These are meant to provide warning to those that are
outside that may not have access to other warning mechanisms," said
Edmond Emergency Management Coordinator Mike Magee. Magee says the voice
comes out of the same speakers as the tornado siren. The siren only
goes off for a tornado warning, but now the voice will warn park goers
about hail, high winds and thunderstorms..."
Central Soaking.
While California and Arizona remain bone-dry, a series of soaking
storms drop as much as 3-4" of rain on Missouri in the coming week; 1-3"
rains quite common from the Mississippi River to the Appalachians.

Can't Quite Shake April.
Highs reach the 60s this weekend into Monday, before falling back into
the 50s by midweek as Canadian air comes surging south. A few showers
Saturday may give way to heavier rain (and embedded T-storms) late
Sunday into Monday - just sprinkles the middle of next week. Hey, at
least it won't snow. Graphic: Weatherspark.
Back To The Future: Are We About To Crack Nuclear Fusion.
The world need's a new, quantum leap in clean energy technology.
Nuclear fusion, similar to the process on the surface of the sun, would
represent a revolution in the energy industry - but are we getting any
closer?
The Guardian reports; here's a clip: "...
For
the uninitiated, it's the kind of big idea that makes your head spin:
we're talking about mimicking the process that powers the stars, heating
hydrogen atoms to temperatures in excess of 100 million degrees celsius
– the point at which they fuse into heavier helium atoms – and
releasing energy in the process. The creation of a self-sustaining
reaction here on earth would be a revolutionary moment for humanity. It
would mean we'd have a near-limitless source of energy that is clean,
safe and cheap. The fuel used for fusion (two isotopes of hydrogen,
deuterium and tritium) is so abundant it will effectively never run out;
one kilogram of it provides the same amount of energy as 10 million
kilograms of fossil fuel..."
The New App That Tracks Your Carbon Footprint - And Lords It Over Your Friends. Yes, there's even an app for that, according to
Grist; here's an excerpt: "
Ian Monroe wants you to beat your Facebook friends at a new game: Who has the lowest carbon footprint? Monroe is the CEO of Oroeco,
a recently launched web app that tracks a user’s personal impact on
climate change. The app not only helps you quantify your own footprint —
based on your spending habits, made possible through linking up with
Mint.com — but by logging in with Facebook it’ll allow you to compare
your carbon sins with those of your virtual community. Ultimately,
Monroe wants to motivate users to emit a little (or a lot) less
greenhouse gas. In other words, go ahead and feel green – with envy,
that is..." (Image: Shutterstock).
"Godzilla Inflation".
As skyscrapers get higher, so must Godzilla (to tower over all those
high-rises and strike fear into the heart of mere mortals cowering
below). Here's an excerpt from a story at
deepseanews.com: "
In
1954 Godzilla was a mere 50 meters (164 ft). In the newest movie,
Godzilla is estimated to be 150 meters (492 ft). For comparison the
Empire State Building in New York City stands at 381 meters (1250 ft).
Incarnations of Godzilla went from 13% of the height of the Empire State
Building to nearly 40% of the height in just 60 years. It took
cetaceans 55 million years to go from 2.5 meters (8.2 ft) to 30 meters

Florida Finds Itself In The Eye Of The Storm On Climate Change.
South Florida will see numerous challenges in coming years related to
rising seas, ever higher storm surges, and salt water encroaching on
fresh water supplies just inland. Here's an excerpt from
The New York Times: "...
A new scientific report on global warming released this week, the National Climate Assessment,
named Miami as one of the cities most vulnerable to severe damage as a
result of rising sea levels. Alton Road, a commercial thoroughfare in
the heart of stylish South Beach, is getting early ripples of sea level
rise caused by global warming — even as Florida’s politicians, including
two possible contenders for the presidency in 2016, are starkly at odds
over what to do about it and whether the problem is even real..." (Image: NASA).
The Southeast U.S. Has Had More Billion Dollar Disasters Than The Rest Of The Country Combined. Here's a clip from a story at
ThinkProgress: "
Heat.
Drought. Sea level rise and invasive species. The Southeast and
Caribbean will escape few of the impacts of climate change, and the
regions are already grappling with how to deal with many of them,
according to the just-released National Climate Assessment. The assessment
calls the Southeast and the Caribbean regions “exceptionally vulnerable
to sea level rise, extreme heat events, hurricanes, and decreased water
availability.” Many of these impacts are already being felt by Southern
states. Florida, in particular, has struggled to adapt to sea level
rise and increased frequency of intense storms, Jennifer Jurado,
Director of the Natural Resources Planning and Management Division in
Broward County, Florida, told ThinkProgress..."

Now A "Pollen Vortex"? Wild Weather May Mean Allergy Nightmare.
The polar vortex certainly delayed allergies across most of the USA,
but we seem to be rapidly making up for lost time. Here's a clip from
NBC News: "...
Susan
Kosisky, a microbiologist and chief of the United States Army
Centralized Allergen Extract Laboratory, reports that daily average
pollen counts from her laboratory in Silver Spring, Md., have been 50
percent or below what is normal for this time of year, which she
attributes to cold temperatures. But before you throw away the tissues,
experts say the slow start could mean a more intense wallop. “It will be
a shorter period by a number of weeks but you will see it all hitting
very intensely,” says Dr. Shulan..."
Million Year Climate Record A Step Closer After Australian Expedition.

record of changes in Earth's climate system; here's an excerpt: "
Antarctic
science's holy grail of a million-year climate record is a step closer

Can The Kochs Hold Back History? Here's a snippet from an Op-Ed at
The New York Times: "...
What
this shows is that you can buy a lie, but you can’t make that lie the
truth. Over the last nine months, three exhaustive studies have shown
that climate change is happening now, and will continue to unfold in
real time, with record droughts in the American West, rising seas along
the Atlantic coast, and global megastorms so catastrophic they will
divert CNN from the missing plane. The climate experts in these studies
are the gold standard — from places like the National Academy of
Sciences and the Royal Society. They are not political hacks looking to
spin something..."
The New Climate Change Argument: Global Warming Is Good For You. Here's a clip from a story at
The Guardian: "...
Has
the denial camp has found its new meme? One that admits the warming is
happening but insists – contrary to the overwhelming evidence – that
it's beneficial? Hardly, says Harvard University professor and science
historian Naomi Oreskes, co-author of Merchants of Doubt. "One thing
these folks have done for a long time is have a kind of repertoire of
arguments, and, depending on circumstances, they trot out different
ones," she said. "This is not new. This is recycled..."
