Wettest Weekend In Nearly A Year? This map shows 24
hours Doppler radar rainfall estimates - it doesn't include Friday's
rain. Some towns around Montevideo and Willmar picked up over 4" of rain
just on Saturday, the south metro of the Twin Cities seeing
considerably more rain (2-3") than the north metro, where closer to 1"
of rain fell yesterday. A wonderfully lousy weekend - farmers and
gardeners are breathing a lot easier today.
4.37" rainfall estimate at Farmington (Dakota County).
2.98" rain fell on Waconia (Carver County) - 24 hour total.
2.7" rain fell at Jordan (Scott County)
2.31" Kimball (Stearns County)
1.9" fell at Chanhassen.
.5 to 1" hail pelted the metro between 1-3 am Sunday
morning, winds over 60 sparked some pockets of damage, numerous tree
limbs down in the Bloomington area. More details from NOAA
here.
One Wild Week. According to SPC there were 2,611
reports of severe weather in the last 7 days, just across the Upper
Midwest. Red dots are tornado or funnel sightings, all those blue dots
are hail, green dots record 24 hour rainfall reports. Saturday's data
will pop in later today - pretty amazing. For an interactive map from

Simmering Down. No more fireworks today; the
heaviest rain, hail and gusty winds pushing to our south/east. Winds
will turn around to the northwest behind a cool frontal passage - skies
may brighten this afternoon, but most of the rain seems to be over now,
with the exception of far southern Minnesota, where rain will linger
into late morning.
A Whole 'Lotta Gray. Clouds will linger into midday,
probably early afternoon, but some partial clearing is possible later
today. In general, if you have something scheduled for outside after 11
am or so, you should be ok. Today won't win any awards for beauty and
splendor, but you won't be running for the basement either. 1 km. vis

.75" diameter hail reported at St. Augusta (Stearns County) at 6:33 pm Saturday.
Wild & Windy. The line of strong T-storms that
swept across the metro area midday Saturday whipped up powerful
sustained winds, clocked as high as 48 mph at 3:46 pm yesterday at
Flying Cloud Airport in Eden Prairie. That's tropical storm force. More
details from NOAA
here.
Gust Front. I'm impressed with the caliber of photos
we're getting - check out this gust front pic, taken by Matt Goyette,
near Spencer, Iowa late Saturday. Check it out on
Twitter. Thanks Matt!
Serious "Hailers". Julie Swanson sent in this photo
from the St. Paul area in the aftermath of Friday's severe storms. Keep
in mind 1" diameter is considered severe (roughly the size of quarters).
Some of these stones were 2" in diameter. That'll put a dimple in your
Prius.
Fine Fishing Opener? The only thing I guarantee is
sunrise and sunset, but I'm cautiously optimistic about the outlook for
Saturday: highs in the upper 60s to near 70 with sunshine, a northerly
breeze at 10 (rising barometer?). Fingers and eyes crossed. Not to be
outdone, Mother's Day looks sunny and a few degrees milder: low 70s.
Hey, a guy can dream. Data above from the European ECMWF model.
Hopeful Fishing Opener Outlook. The heavy rain is
over, for now. The amazing news: all the models are hinting at a dry
Saturday. I know, it's early... Map: Iowa State University meteorology

Perigree "Super Moon" On May 5-6. OK. I didn't play
it up too much in the blog because I feared clouds would get in the way
(and they did). You may get another shot tonight. Details from
NASA: "
The
full Moon has a reputation for trouble. It raises high tides, it makes
dogs howl, it wakes you up in the middle of the night with beams of
moonlight stealing through drapes. If a moonbeam wakes you up on the
night of May 5th, 2012, you might want to get out of bed and take a
look. This May’s full Moon is a "super Moon,” as much as 14% bigger and
30% brighter than other full Moons of 2012. The scientific term for
the phenomenon is "perigee moon." Full Moons vary in size because of
the oval shape of the Moon's orbit. The Moon follows an elliptical path
around Earth with one side ("perigee") about 50,000 km closer than the
other ("apogee"). Full Moons that occur on the perigee side of the
Moon's orbit seem extra big and bright."
Flood Watch In An Area Experiencing Severe Drought. "
Only in Minnesota can you be ankle-deep in mud with dust blowing in your face" the adage goes.
Go figure: much of southern Minnesota was running at 3-6" long-term
rainfall deficit since last autumn, before yesterday. The soil is now
saturated/waterlogged across much of central and southern Minnesota; the
Flash Flood Watch has been discontinued.
Sunday Severe Risk. Strong/severe storms are likely
again today from Des Moines and Madison to Chicago and St. Louis, on
south to Kansas City and Tulsa - a second severe risk from Birmingham to
Macon and Florida's Emerald Coast. Map:
SPC.
"Supercell." Wow. I wish I could be articulate, but
when I saw Paul Zunkel's photo taken near Fairmont late Friday I almost
fell off my sofa. Well done - a perfect example of a rotating
"supercell" thunderstorm. This is the same cell that dropped as many as 9
tornado touchdowns (from the same parent thunderhead) all the way from
Worthington to near Kiester.
Iowa "Haboob". I know - kind of a funny word;
something you might expect to see in Phoenix or Las Vegas - an advancing
wall of dust and dirt, whipped up by an advancing gust-front in Orange
City, Iowa. I don't think this was a "gustnado", but rather the symptom
of a wall of wind picking up dirt/topsoil into a swirling, seething
cloud that totally enveloped this town. Sheric Hull captured this
footage on the campus of Northwestern College. The (remarkable) YouTube
clip is
here. Details: "
This
is a gustnado(short for gust front tornado) that formed in Orange
City, IA on the Northwestern College campus. A gustnado is similar to a
tornado in the fact that it rotates, but it's direction is horizontal
rather than a vertical like an actual tornado." (video clip rated
PG for salty language - if I saw this thing approaching my neighborhood I
might be using the same words. Sorry mom).

Ballfield - or Instant Lake? Thanks to Chris
Blumberg, who sent in this photo of a flooded softball field in the

rains.
Finally, Looks Like Spring. The GFS is hinting at
consistently lukewarm temperatures between May 13 - 21, highs in the 60s
and 70s. No more frosty relapses. I think you're safe to dig in and
plant your annuals without any nasty Canadian surprises.

The World's Most Offensive Billboard Taken Down.
Comparing climate scientists and reporters to "mass murderers and
madmen"? The idiots at The Heartland Institute took down their scathing
billboard late Friday, but damage has been done to what little
credibility and stature they had left. The Chicago Tribune has an update
below.
“
The area of climate change has a dramatic impact on national
security,” Panetta said. “Rising sea levels, severe droughts, the
melting of the polar caps, the more frequent and devastating natural
disasters all raise demand for humanitarian assistance and disaster
relief.” - excerpt from a statement by Defense Secretary Leon Panetta in "The Hill"; details below.
"
The trend lines for the number and cost of U.S. natural
disasters have steadily risen since 1980, according to the Insurance
Information Institute, an industry trade group. Losses from
thunderstorms have grown fivefold. Losses from winter storms have
doubled since the early 1980s." - from a Chicago Tribune article; details below. Wall cloud photo courtesy of Larry Maloney.

Wet Start To May For Some. Here's an excerpt from Dr. Mark Seeley's
WeatherTalk blog for May 4: "
Strong
thunderstorms crossed the state overnight from May 1st to 2nd
producing numerous reports of heavy rainfall, hail, strong winds, and
even tornadoes. NOAA Storm Prediction Center received reports of brief
tornado touchdowns in Pope and Stearns Counties between 9:00 and 10:00
pm Tuesday night. No serious damage reports from tornadoes were
evident. There were numerous reports of strong winds and large hail
(1-2 inches in diameter) from many western and southern counties. Sauk
Rapids reported wind gusts to 64 mph while Wabasha reported winds up to
74 mph. Many observers reported rainfall from 0.75 inches to 1.50
inches, and some reported new record rainfall amounts for May 2nd.
Among the new record amounts were 2.20 inches at St Francis; 2.10 inches
at Elk River; 2.05 inches at Rush City, Slayton, and Windom; and 1.63
inches at Rice. The campus of St Cloud State University reported a
rainfall of 3.11 inches."
End To The Drought In Sight? The map above shows a
long-term rainfall deficit of 1.5 to near 7" across Minnesota - this is
how much additional rain we need to end the drought. As much as 1-2" of
rain may fall over the weekend, putting a big dent in our drought - if
these trends continue much of Minnesota may be drought-free within a
couple of weeks. But we need another 3-5"+ to start start raising lake
water levels significantly. I think the worst of the drought is behind
us now. It was a $500 million weekend for farmers across the Upper
Midwest, no question.
"The Puddles Page". Looking for rainfall information? The Minnesota Climatology Working Group has put together a
terrific resource to
get close to real-time rainfall data, in tabular or map form. You can
access information for the metro, the state, or the entire nation, on a
state-by-state basis. Well done.
Severe Flash Flooding In Flint, Michigan. The same
"supercell" that spawned tornado warnings across central Michigan dumped
excessive rainfall amounts on Flint. Details from
AP's YouTube page: "
An
overnight storm dumped nearly half a foot of rain on the Flint area
and drenched other parts of Michigan, killing power to neighborhoods,
stranding cars on roadways and forcing the boat evacuation of some
residents."
Water Water Everywhere. Britons Baffled By Simultaneous Drought And Flood. Here's an excerpt of an AP story at
The Washington Post: "
LONDON
— Sodden fields. Deep puddles. Flash floods. This is what drought looks
like in Britain. Last month, water authorities banned 20 million U.K.
homeowners from using hoses to water their lawns or wash their cars,
saying two exceptionally dry winters had plunged much of Britain into
drought. Since then, the rain has hardly let up. Official figures show
that April was both cooler than average and the wettest in a century,
leaving a trail of flooded properties, canceled events and grumpy
residents. But officials insist the drought and the watering ban remain —
to the bafflement of many Britons."
Satellites At Risk. Budget cuts are threatening the constellation of weather satellites we use to monitor Earth. Here's an excerpt of an Op-Ed at
The Washington Post: "
The National Research Council (NRC) reported Wednesday that the U.S. system of earth observation satellites is
“beginning a rapid decline” and is “at risk of collapse.” Already, the
network of satellites that NASA and the National Oceanic and
Atmospheric Administration (NOAA) use to monitor weather and climate
relies on instruments that are operating beyond their intended use or
long past their expiration dates. They will eventually run down their
batteries or otherwise fail. The NRC reckons that the country could be
left with as little as a quarter of its current number of earth observation satellites by 2020." (image above: NOAA).

Worst. Airline. Ever. Again. I'm feeling even better about flying Delta these days. Here's a snippet of an article at
portfolio.com: "
A Seat 2B column on the dreadful state of United Airlines in 2008 cribbed a line from The Simpsons for its headline: "Worst.
Airline. Ever." Four years later, there's ample reason to revive the
line and dub the United Airlines of 2012 "Worst. Airline. Ever. Again."
Two years to the day after it announced its merger with Continental Airlines,
United is lagging its competitors among the legacy carriers by most
any financial measure or service metric. The airline's fractured
employee groups are unhappy, and C-suite executives are bolting. Many
of its best and most profitable customers are in open revolt, and
average travelers are filling United's Facebook page
with tales of woe. The airline's management seems alternately clueless
and arrogant and unwilling or unable to fix what's gone awry."
Inside The First Production-Ready Electric Airplane. Here's an interesting article at
popsci.com: "
Engineers have historically faced two obstacles when designing electric aircraft.
Batteries that run the electric motors have been too heavy and not
energy-dense enough to provide sufficient power. And the consequences of
failure were too high: Running out of power would all but assure a
crash landing. But in the past several years, says Paul Peterson, the
founder and CEO of the Portland, Oregon, aeronautics company Volta
Volare, off-the-shelf electric-car batteries and motors have become
light, powerful and efficient enough to make electric—or at least
hybrid—flight viable. This spring, Volta Volare will begin testing its
four-passenger GT4. Constructed around a standard airframe, the plane
runs on a hybrid powertrain similar to the one in the Chevrolet Volt,
with batteries plus a backup gasoline engine."

The Battery-Driven Car Just Got A Lot More Normal. Here's an excerpt of a New York Times article: "
CRITICS of electric vehicles
say they are too expensive and lack sufficient driving range. But I
wonder if those gripes would disappear if the E.V.’s on sale weren’t so —
let’s not mince words — homely. I adore my all-electric Nissan Leaf,
but its wide rear end, bulging headlights and odd proportions evoke a
Japanese gizmo aesthetic that doesn’t necessarily appeal to mainstream
American car buyers. Enter the handsome 2012 Ford Focus
Electric, the first all-electric car from an American automaker in the
21st century. Ford will begin selling the electric version of the new
Focus in the next few weeks in California, New York and New Jersey,
followed by 19 additional markets in the fall."

Taking E-Mail Vacations Can Reduce Stress, Study Shows.
No kidding. Technology was supposed to set us free; instead we're all
connected 24/7. I had one recent Facebook "friend" harrass me because I
didn't immediately respond to her post - unreal.
The New York Times has more: "
You probably don’t need a doctor or scientist to tell you this, but your e-mail could be killing you. A new study released Thursday
by the University of California, Irvine, which was co-written with
United States Army researchers, found that people who do not look at
e-mail on a regular basis at work are less stressed and more productive.
The study, “A Pace Not Dictated by Electrons: An Empirical Study of
Work Without Email,” looked at 13 workers in a typical office setting
and asked them to discontinue e-mail for five days. The results were
that during the e-mail hiatus, these people spent longer periods of
time focusing on a single task at work and shifted between computer
windows much less than those who were slaves to their in-box."
Flow Concept Turns Wind Into Light With Novel Bamboo Turbine. The rate of innovation on clean-energy options continues to amaze me. Here's an excerpt from
gizmag.com: "
Grid-powered
street lighting is something that many of us take for granted, but
there are parts of the world where electricity is a scarce resource and
when the sun goes down, local pedestrian traffic in areas where public
lighting is not abundant can all-but cease due to safety concerns. In
searching for an inexpensive off-grid solution for places like the
Colombian city of Cartagena, designer Alberto Vasquez looked to the
wind for help. His Flow concept makes use of readily-available bamboo
for the construction of a vertical wind turbine in a similar vein to
the Power Flowers
concept, but with LED light modules at the end of each blade. As the
wind catches the blades, the LEDs light up the walkway beneath."

Camping Out On I-94. WeatherNation TV meteorologist
Todd Nelson sent me this photo of stop-and-go traffic on I-94, at 9:45

afternoon...or evening...or night? Don't answer...

Weather Treadmill
"Only in Minnesota can you be ankle-deep in mud
with dust blowing in your face." It's been a surreal 48 hours; flash
flooding reported in some drought-stricken counties across southern
Minnesota. I just wish Mother Nature would take one weekend off.
"Mamma, don't let your kids grow up to be meteorologists." I love the weather, but it's a full-time, 24/7 gig.
"You're up at the cabin. Relax! Here, grab a
rake," my wife pleaded yesterday. "Honey, there's severe weather over
southern Minnesota - I need to update the blog." So there I was, hunched
over a hot laptop, enjoying my "day off".
Maybe hooking up Wi-Fi at the cabin wasn't such a
great idea after all. Bottom line: meteorology isn't an 8 to 5 job. You
don't predict the weather; you live it, 7 days a week. No complaints,
it still beats punching a clock.
"Paul, where else can you be wrong half the time and still get paid!" Haha. LOL. Gag me with a Doppler.
A wet start to May is taking the edge off our
drought; we've gone from dusty to standing water in some fields. The
storms are gone, a cool frontal passage dries us out later - the sun
(remember?) could make a cameo appearance by late afternoon or evening.
Minnesota's Fishing Opener? Friday storms give rise to weekend sun and low 70s. We may just luck out.

Weather Is On A Wild Ride, But Is It Actually Getting Weirder? Here's an excerpt from
The Chicago Tribune: "...
After
all, U.S. weather records have been toppling like tulips in a hail
storm, more than 3,000 records last year alone, including one big one,
what the National Oceanic and Atmospheric Administration calls $1
billion weather disasters. These are events that, since 1980, have
caused an inflation-adjusted $1 billion in damages. In a typical year,
the United States sees three or four of them. In 2011, there were a
record 14. "The weather is definitely weird," said Jeff Masters,
director of meteorology for the website Weather Underground. He's seen
extreme events in the last two years that he had not seen in a 30-year
career. "The climate is certainly much different today than when I was
growing up." Global warming is partly to blame, inducing something akin
to 'roid rage in the Earth's atmosphere."

Heartland Takes Heat Over Billboard. Yes, the
world's most offensive billboard was taken down after 1 day, but the
damage has been done to whatever credibility Heartland Institute had
left.
The Chicago Tribune reports: "
For
about a day last week, a billboard featuring a mug shot of the
Unabomber, Ted Kaczynski, loomed over the inbound Eisenhower Expressway
in west suburban Maywood, posing a question to drivers cruising toward
the city: "I still believe in Global Warming," the electronic sign said
in large red letters. "Do you?" The ad, paid for by the Heartland
Institute, a Chicago-based group, was to be the first in a series of
billboards equating those who believe in global warming with infamous
figures — including Fidel Castro and Charles Manson — who have allegedly expressed the same belief, according to the institute."
Who Still Supports The Heartland Institute? Here's an excerpt of a
Huffington Post article from Shawn Lawrence Otto: "
Here are some other leading U.S. corporations and foundations who support the Heartland Institute.

As
you may have heard, the Heartland Institute, a right-wing

that’s getting widely pilloried on the Web — it compares people who
accept climate science as legitimate to Osama Bin Laden, Charles Manson,

Panetta Warns Climate Change Having "Dramatic Impact" On National Security. Here's an excerpt from "
The Hill"...."
But
the Pentagon's adoption of environmentally sensitive practices was
driven more by the department's dire fiscal situation than politics,
Panetta said on Tuesday. DOD spent roughly $15 billion to fuel its
fighters, tanks and ships in 2012, the Defense chief said. The Pentagon
spends $50 million on fuel each month to keep combat operations in
Afghanistan going, Panetta added. As oil prices continue to skyrocket,
the department "now [faces] a shortfall exceeding $3 billion of
higher-than-expected fuel costs this year," according to Panetta. In
order to dig its way out of that financial hole, DOD has no choice but
to look to alternative fuel technologies. Pentagon officials plan to
invest more than $1 billion into developing those technologies in
fiscal 2013, he said."
Connecting The Dots Between Climate Change And Extreme Weather. Here's a snippet of a recent post from Dr. Jeff Masters in his excellent
Wunderblog: "
Connecting
the dots between human-caused climate change and extreme weather
events is fraught with difficulty and uncertainty. One the one hand,
the underlying physics is clear--the huge amounts of heat-trapping
gases like carbon dioxide humans have pumped into the atmosphere must
be already causing significant changes to the weather. But the weather
has huge natural variations on its own, without climate change. So,
communicators of the links between climate change and extreme weather
need to emphasize how climate change shifts the odds. We've loaded the
dice towards some types of extreme weather events, by heating the
atmosphere to add more heat and moisture. This can bring more extreme
weather events like heat waves, heavy downpours, and intense droughts.
What's more, the added heat and moisture can change atmospheric
circulation patterns, causing meanders in the jet stream capable of
bringing longer-lasting periods of extreme weather. As I wrote in my
post this January, Where is the climate headed?" Photo credit: "Restless Skies".
Climate Change Is Real And Here: What You Can Do NOW To Protect Your Building. An interesting post from
Habitat: "
Based
on the model of probability used by New York City's task force on
climate change, extreme precipitation is expected, and in a greater
frequency, intensity and duration in coming decades. Greater downpours
will put considerable strain on the combined sewage outflow system of
the city. Condos and co-ops can do their part to mitigate this by
installing green roofs. These structures can absorb and capture the
excess rainfall during intense precipitation events, helping to
forestall sewage overflows. Additionally, rainfall can be captured and
re-appropriated for use in building systems or, in some cases, toilet
flushing. Doing this not only saves on water, it also hygienically
preserves quality, since the increased flooding makes the water grid
susceptible to dirt."
Is Climate Change Real? For The Thousandth Time - Yes. Here's an excerpt from a story at
KQED: "
From PBS NewsHour yesterday, a story about the difficulties teachers confront when discussing climate science in the face of both skeptical
parents and hostile state laws. From the report: CHERYL MANNING, high
school science teacher: They hear it on the news. They see it in the
newspaper. They hear their parents talking about it. There are people
who say that climate -- the climate may be changing, but it's not our
fault, or the climate isn't changing at all; this is a natural cycle.
There are all sorts of things that the kids hear. They want
clarification."

Correcting Science Myths: "There Is No Consensus On Climate Change". Here's a post that often comes up from perpetual climate-deniers: "
There is no consensus
The Petition Project features over 31,000 scientists signing the
petition stating "There is no convincing scientific evidence that
human release of carbon dioxide will, in the forseeable future, cause
catastrophic heating of the Earth's atmosphere ...". (Petition Project)"
Skeptical Science's response: "
97%
of climate experts agree humans are causing global warming. Science
achieves a consensus when scientists stop arguing. When a question is
first asked – like ‘what would happen if we put a load more CO2 in the
atmosphere?’ – there may be many hypotheses about cause and effect.
Over a period of time, each idea is tested and retested – the
processes of the scientific method – because all scientists know that
reputation and kudos go to those who find the right answer (and
everyone else becomes an irrelevant footnote in the history of
science). Nearly all hypotheses will fall by the wayside during this
testing period, because only one is going to answer the question
properly, without leaving all kinds of odd dangling bits that don’t
quite add up. Bad theories are usually rather untidy. But the testing
period must come to an end. Gradually, the focus of investigation
narrows down to those avenues that continue to make sense, that still
add up, and quite often a good theory will reveal additional answers,
or make powerful predictions, that add substance to the theory. When
Russian scientist Dmitri Mendeleev constructed his periodic table of
elements, not only did he fit all known elements successfully, he
predicted that elements we didn’t even know about would turn up later
on – and they did!"
