14 F. high in the Twin Cities Thursday.
30 F. average high on December 5.
40 F. high on December 5, 2012.
Trace of snow reported yesterday.
Windchill Advisory in effect today for a chill factor dipping to -20 to -25F at times.
30s (above zero) one week from today.
Embrace the Burn
A
Minnesota winter is a steep learning curve. I remember being baffled,
horrified, then deeply impressed the first time I saw someone RUNNING in
subzero cold. I had moved to a state populated by a race of attractive
aliens with cold-weather superpowers.
Early on someone pulled me
aside with good advice: "Don't hide in the basement or hibernate in
front of the tube. Embrace winter! Put on some cross-country skis, take
the kids skating, build a snowman. The best antidote is to throw
yourself, headfirst into winter.
As long as you're properly
dressed. I've been following the no-exposed-skin rule since reaching
middle age and it will apply to everyone thru the first half of next
week. Windchill advisories are posted; we may see 5 nights/row below
zero - highs Saturday may hold below zero.
Character-building cold.
This
may wind up being the coldest stretch since 2007. According to Pete
Boulay, at the MN Climate Center, we enjoyed 10 nights/row below zero in
February, 2007. The record? 36 nights/row below zero in 1936.
More deep breaths: 30s return in a week, and you'll be amazed how good freezing feels a week from today.
Yes,
misery loves company. Freeze warnings are posted for Phoenix, even San
Francisco. Most of America is shivering right along with us!
Consecutive Nights Below Zero at MSP.
Data above from the Midwest Regional Climate Center shows 10 nights/row
below zero in 2007, from February 1 to February 10. 1996 saw a run of
15 consecutive subzero nights, 23 in 1976 and early 1977. Here's more
information from Pete Boulay, at the Minnesota Climatology Working
Group: "
It's been a few years since we've had a lengthy stretch of
overnight lows of 0 or below in the Twin Cities. The last time there
were 10 nights in a row of at or below zero temperatures in the Twin
Cities was in Feb 2007. The record is 36 nights in a row from 1/18 1936
to 2/22/1936."
6 AM Saturday Morning.
Cold enough for 'ya? I thought so. Temperatures bottom out early
Saturday, double digit negative numbers pushing into much of Minnesota,
as cold as -10 to -12F in the outlying suburbs of the Twin Cities. Winds
will ease up on Saturday so chill factors won't be quite as obscene.
Map: NOAA and Ham Weather.
Character-Building.
Temperatures hold below zero from this afternoon into Sunday morning
across most of Minnesota. Highs Saturday may blip up to zero in the
metro (urban heat island), but we're looking at roughly 36 consecutive
hours below zero. Not days, hours. Another surge of subzero weather is
likely Monday PM, another clipper drags a quick shot of bitter air into
town late Tuesday into much of Wednesday. And then the recovery begins;
30s possible by Friday. Which will feel like a Godsend. Graph:

35.3" North Of Two Harbors.
Surreal, and here I thought predicting 2 feet for the North Shore was
going out on a limb. Talk about turbocharged lake effect. Here's an
excerpt from Dr. Mark Seeley's always informative
WeatherTalk Newsletter: "
Most
of the state reported measurable snowfall during the first week of
December. Monday through Wednesday of this week (Dec 2-4) brought almost
continuous snow to many areas of northeastern Minnesota, especially the
north shore along Lake Superior. The greatest amount of snowfall
reported by a National Weather Service observer came from 7 miles north
of Two Harbors where 35.3 inches was recorded. The Duluth Weather
Service Office reported a storm total of 23.3 inches, and Duluth public
schools were cancelled two consecutive days over the 3rd and 4th. Tofte
reported 25 inches and Wolf Ridge reported 20.7 inches for the week.
Many other areas of the state accumulated 5 to 10 inches of snowfall
this week, while areas of southeastern Minnesota received mostly rain
and drizzle..."

Alerts Broadcaster Briefing: Issued Thursday, December 5, 2013.
*
Leading edge of bitter air sparks band of heavy snow and ice from
northern Texas and Oklahoma into Arkansas and Middle Mississippi Valley
and Ohio Valley over the next 36 hour. Very significant snow is expected
from southern Illinois and southern Indiana into northern Kentucky and
much of Ohio.
* Ice Storm Warnings posted from near Oklahoma City
to Little Rock and Memphis for .25"+ amounts of glaze ice tonight into
Friday.
* Enhanced risk of frostbite north central USA as wind chill values dip to -30F by Saturday morning.
Current Warnings.
NOAA has issued Ice Storm Warnings from southeastern Oklahoma into much
of central Arkansas and western Tennessee, for the potential of as much
as 1/2" of glaze ice. A band of heavy snow will set up just north/west
of the ice band, impacting Oklahoma City, Hot Springs, Evansville,
Louisville and Cincinnati. Wind Chill Advisories may have to be upgraded
to warnings as the combination of bitter cold and strong winds create
wind chill factors as cold as -25 to -40 from Fargo into the Twin
Cities; a wind chill dipping to -15F in Chicago by Saturday. Map: NOAA.
84 Hour Snowfall Prediction.
A storm spinning up along the leading edge of arctic air creates a
swath of snow and ice from northern Texas and Oklahoma into the Ohio
Valley through Saturday - a couple inches of slushy snow may extend into
Washington D.C. and Baltimore by Sunday, where most of the
precipitation will fall as a cold rain. NAM guidance: NOAA and Ham
Weather.
Selected City Amounts.
The extent and intensity of the bitter cold is impressive: 3" snows
predicted for Sacramento, California (which seems high to me, but not
out of the question). Models print out close to 10" snow from Louisville
to Dayton and Cincinnati, Ohio - even if these amounts are slightly
inflated this is still going to be a plowable/crippling snowfall event
for much of the Ohio Valley Friday into Saturday.
Ice Potential Next 24 Hours.
The red-shaded area shows the greatest potential for glaze ice
(freezing rain) into Friday morning, from near Wichita Falls and the
suburbs of Dallas to Little Rock, Hot Springs, Memphis, Cairo and
Evansville. Map: NOAA and
Ham Weather.
Potentially Paralyzing Ice.
The forecast from early Friday into early Saturday shows the greatest
risk of ice from east of Little Rock to Memphis and western Kentucky.
This storm will probably impact the grid, with a heavy enough
accumulation of glaze ice to bring down power lines.
I expect numerous power outages from Oklahoma and Arkansas into the Ohio Valley within 24-48 hours.
Icy Trouble Zone.
Here is another computer model summarizing the ice potential. Dallas
may avoid the worst of the icing, but Hot Spring, Fayetteville and
Little Rock, Arkansas, as well as Memphis, Cairo, Illinois and
Evansville/Bowling Green, Kentucky may see serious icing capable of
disrupting early weekend travel plans and the power grid. (Map: NOAA).
Summary:
We're still on track for a very significant period of heavy snow and
ice, impacting the Southern Plains, Middle Mississipi Valley and Ohio
Valley over the next 48 hours. This still will impact travel by land and
air, with a high probability of power disruptions in some communities
due to a heavy accumulation of glaze ice. Accumulating snow may extend
into New England over the weekend, with a few slushy inches from D.C. to
Philadelphia by Sunday, but confidence levels for East Coast
accumulation is still quite low - we need to see more data. Meanwhile
the coldest air in at least 4 years will create potentially dangerous
wind chills and an enhanced frostbite risk from the Upper Midwest into
the Great Lakes.

These 11 Cities May Completely Run Out Of Water Sooner Than You
Think. We will take many things for granted in the 21st century. Access
to clean, reliable water is not one of them, especially west of the
Mississippi, but some cities you might not suspect are on this list.
Here's a clip from a long and thorough story at
Huffington Post: "
Columbia University's water scarcity study showed most of California, from San Diego all the way to Santa Barbara, at high risk for water problems. And CIRES' study
showed much of the same areas with high to moderate stress on regional
watersheds from the coast and all the way inland. Los Angeles relies on
importing much of its water from the Colorado River system which has
long provided the American West with water -- seven states in all that
are home to almost 40 million people. But demands on the river are often
cited as unsustainable, due to predicted population increases and
climate change. A recent report from the U.S. Bureau of Reclamation
predicts a water supply and demand gap in the Colorado River of about
3.2 million-acre feet by 2060 -- roughly five times the amount of water that Los Angeles uses in a year..." (Image: NASA Earth Observatory).

David Hathaway, a NASA scientist whose new paper in Science confirms
the existence of giant cells, was able to find the structures by
tracking supergranules over time. Hathaway and fellow researchers used

Top 10 Fuel Efficient Vehicles For 2014. A few more surprises on this list, courtesy of
Ecowatch. Here's the intro: "
The government’s ranking
of the 10 most fuel-efficient cars for 2014 doesn’t sport any fuel at
all. The 10 vehicles on the list by the U.S. Environmental Protection
Agency and Department of Energy are all either 100 percent electric (EV)
or plug-in hybrids. Keeping in mind that one gallon of gasoline equates
to 33.7 kilowatt-hours, the vehicles on the list all achieve at least
58 miles per gallon equivalent (MPGe). Though the Nissan LEAF is the highest selling EV, it did not make the cut. None of Elon Musk‘s Tesla models are listed either..."

Why You Should Give LED Lightbulbs For Christmas.
Seriously.
The Daily Beast has an interesting analysis about why LED bulbs pay longterm dividends; here's a clip: "...
And
yet not many people will go out and make the switch. Our existing bulbs
tend to work, and we are not yet conditioned to think of them as
capital investments. “This isn’t a disposable commodity,” said Watson.
“It is a transferrable asset.” Behavioral economists have taught us that
we are often wired to ignore the long-term financial benefits of a
transaction in favor of perceived short-term benefits. That’s why I
think LEDs make excellent gifts. For the giver, these bulbs offer a huge
amount of leverage. You pay $22 out of pocket for a 75-watt bulb, but
you are in effect giving the recipient an annuity that will pay out
$215.50 over its lifetime. No savings bond promises that kind of bang
for the buck. And even though the recipient might recoil at first, he
will come around once you point that they’re getting a household utility
and an income stream—all with no upfront cost." (Image above: The Daily Beast).

Netlix's War On Mass Culture. It turns out binge viewing is just the beginning, as reported in an eye-opening story at
New Republic; here's a clip: "...
And
that’s why what Netflix is trying to do is so audacious. For the past
two years, the Silicon Valley company has been making a major push into
original programming, putting out an ambitious slate of shows that have
cost Netflix, which had profits of $17 million in 2012, hundreds of
millions of dollars. Because of the relative quality of some of those
series, such as “House of Cards” (a multiple Emmy winner) and “Orange Is
the New Black,” they’ve been widely interpreted as part of an attempt
to become another HBO. Because every episode of every show is made
available to watch right away, they’re also seen as simply a new twist
in on-demand viewing. But in fact the company has embarked upon a
venture more radical than any before it. It may even be more radical
than Netflix itself realizes..."
The Rise And Fall Of Blackberry: An Oral History.
Creative disruption is happening faster than ever. Remember, oh, 6-7
years ago when everyone was walking around glued to their "crackberrys"?
Then came the iPhone, then Android, and Blackberry didn't react to the
disruption until it was too late. Here's a clip from this week's cover
story at the always-excellent
Bloomberg Businessweek: "
In
1984, Mike Lazaridis, an engineering student at the University of
Waterloo, and Douglas Fregin, an engineering student at the University
of Windsor, founded an electronics and computer science consulting
company called Research In Motion, or RIM. For years the company
tinkered in obscurity, until it focused on a breakthrough technology: an
easy, secure, and effective device that allowed workers to send and
receive e-mails while away from the office. They called it the
BlackBerry. RIM grew into one of the world’s most valuable tech
companies. The BlackBerry became the indispensable accessory of
business executives, heads of state, and Hollywood celebrities—until
iPhone and Android came along and spoiled the party. Today the company,
which has been renamed, simply, BlackBerry (BBRY),
is burning through cash as sales keep falling. On Nov. 21, BlackBerry
shares closed at just above $6, the lowest it’s been in almost 15 years..."

Climate Stories...
Large Companies Prepared To Pay Price On Carbon.
The New York Times has the article - here's an excerpt: "
More than two dozen of the nation’s biggest corporations, including the five major oil
companies, are planning their future growth on the expectation that the
government will force them to pay a price for carbon pollution as a way
to control global warming.
The development is a striking departure from conservative orthodoxy and
a reflection of growing divisions between the Republican Party and its
business supporters. A new report by the environmental data company CDP
has found that at least 29 companies, some with close ties to
Republicans, including ExxonMobil, Walmart and American Electric Power, are incorporating a price on carbon into their long-term financial plans..."

Experts Say The IPCC Underestimated Future Sea Level Rise. St. Thomas climate scientist John Abraham has the story at
The Guardian; here's the introduction: "
It looks like past IPCC predictions of sea level rise were too conservative; things are worse than we thought. That is the takeaway message from a new study out in Quaternary Science Reviews and from updates to the IPCC report itself. The new study, which is also discussed in depth on RealClimate,
tries to determine what our sea levels will be in the future. What they
found isn't pretty. Predicting of sea level rise is a challenging
business. While we have good information about what has happened in the
past, we still have trouble looking into the future. So, what do we
know? Well it is clear that sea levels began to rise about 100 years
ago. This rise coincided with increasing global temperatures..."

Obama To Feds: Boost Renewable Power 20 Percent. AP and
ABC News have the article - here's a clip: "
Saying
the government should lead by example, President Barack Obama is
ordering the federal government to nearly triple its use of renewable
sources for electricity by 2020. Obama says the plan to use renewables
for 20 percent of electricity needs will help reduce pollution that
causes global warming, promote American energy independence and boost
domestic energy sources such as solar and wind power that provide
thousands of jobs. Obama announced the plan Thursday as part of a
wide-ranging, second-term drive to combat climate change and prepare for
its effects. A plan announced in June would put first-time limits on
carbon pollution from new and existing power plants, boost renewable
energy production on federal lands and prepare communities to deal with
higher temperatures..."
Worst Case Scenario For Oil Sands Industry Has Come To Life, Leaked Document Shows. Pulitzer-prize winning
InsideClimate News has the story; here's an excerpt: "...
The
document identifies nearly two-dozen environmental organizations
leading the anti-oil sands movement and puts them into four categories:
radicals, idealists, realists and opportunists—with how-to's for
managing each. It also reveals that the worst-case scenario presented to
industry about the movement's growing influence seems to have come to
life. The December 2010 presentation by Strategic Forecasting, or Stratfor,
a global intelligence firm based in Texas, mostly advised oil sands
companies to ignore or limit reaction to the then-burgeoning tar sands
opposition movement because "activists lack influence in politics." But
there was a buried warning for industry under one scenario: Letting the
movement grow unopposed may bring about "the most significant
environmental campaign of the decade..."
