62 F. record high in the Twin Cities Tuesday. Old record was 59 in 1930)
31 F. average high on February 21.
37 F. high in the metro area on February 21, 2016.
February 22, 1922:
A blizzard, ice storm and thunderstorms all occur on the same day
across Minnesota. Winds hit 50 mph in Duluth while thunderstorms were
reported in the Twin Cities. Heavy ice over southeast Minnesota with 2
inches of ice on wires near Winona. Over two inches of precipitation
fell. This was also one of the largest ice storms ever in Wisconsin
history.
From Fake Spring to Real Blizzard in 36 Hours?This
week feels like a Meteorology 001 final exam: rain, thunder, fog,
record warmth, blizzard potential. Wait, say what? You heard right.
There's a small but growing risk of an old fashioned snowy dumping by
Friday. Although, as a recovering snow-lover, I keep asking "what can go
wrong, and what time?"
Will planets align - or is this another
cruel false alarm for snow aficionados? Confidence levels remain low; a
slight wobble in the storm track of only 50-75 miles will make the
difference between 3 inches and 13 inches. Right now it appears the best
chance of 6-10 inches or more will come north and west of the Twin
Cities but more tweaks in the snowfall outlook are likely as we zero in
on the final storm track. Friday looks like the roughest travel day -
and the lowest mile of the atmosphere should be cold enough for all-snow
north and west of MSP; mostly-snow in the immediate Twin Cities.
Buyer
beware: if the storm track shifts your results may vary. Either way
it's a subtle (yet blunt) reminder that, no, spring is NOT here.
Record
warmth, 60s in February - this nice little daydream we've enjoyed
together, will soon give way to reality. March kicks off with highs in
the 30s, where we should be.
Winter Storm Watch.
I haven't seen wording like this from the local National Weather
Service office in a long time. On our (patented, trademarked, Judge
Judy-certified) snowstorm scale from nuisance to plowable to crippling
this will probably fall somewhere between plowable and crippling.
Record Territory Again Wednesday.
Today's all-time record in the Twin Cities is 57F in 1930. We'll come
very close. The local National Weather Service office has
more details. Tuesday's high hit a record 62F in the Twin Cities; that's average for
April 23.
A Real Snowstorm?
I know. I know. The drumbeat of media hype is getting louder and snow
lovers are understandably skeptical. It doesn't snow here anymore! We
always find a way to get cheated. "Take the predicted snowfall amounts
and divide by two - that'll be closer to reality!" Perhaps. Model trends
suggest that significant snow is increasingly likely, and this storm
may fall between plowable and crippling. Where the zone of "crippling"
snow (1-2 feet + winds stirring up near-blizzard conditions Thursday
night into Friday morning) is still unclear, but there's little doubt
that Friday commutes will be disrupted. You just new that after a run of
60s in mid-February the weather would turn on us. You could have
scripted this.
Blizzard Potential Friday?
Our internal BPI (Blizzard Potential Index) shows moderate to high
values pushing across southern Minnesota into western Wisconsin on
Friday. You can see a slight shift in Tuesday's NAM model runs. Source:
AerisWeather.
Shifting Track.
Latest (NAM) guidance shifts the heaviest snow band north and west of
the Twin Cities. A more northward storm track might pull a brief mix of
snow, sleet and freezing rain as far north as the Twin Cities Thursday
night, taking the edge off the heaviest amounts in the immediate metro -
with all snow just north/west of MSP. A 50 mile jiggle in the storm
track will mean the difference between 4-5" of slush and a cool foot of
snow. Future snowfall product (12 KM NAM) from NOAA and
Tropicaltidbits.com.
What Can Possibly Go Wrong? I
have to keep asking that question, because the vast majority of the
time we seem to miss out on the heaviest snow band. There's always an
excuse. "It went north, it went south, no - it went west!" Oh, the
indignity. My excitement level is ratcheting up with every new model
run. Odds favor a plowable snowfall, even in the immediate metro. A
foot? I wouldn't rule it out but if you like snow it's still a little
early for joyous celebration. Predicted model amounts above: Iowa State.
Snowiest Place in New York has 25 Feet and Counting. MSN.com documents the snowy wonderland of Oswego County, New York - ground zero for lake effect snow squalls: "
For most in upstate New York, a foot of snow is an intimidation.
For Carol Yerdon, it’s a milestone. By Sunday morning, more than 24
feet of snow already had fallen this winter in the corner of Oswego
County where Yerdon lives. Then it began to snow again. A foot or more
was in the forecast. By noon Sunday, enough fresh snow was on the ground
for Yerdon to hit her mark. “Yes we did it! We hit 300 inches,” Yerdon
said. “Just 125 inches to go to break the record!...”

snow forecast through the weekend."
The Weather Honeymoon Is Nearly Over.
It sure was nice while it lasted, unless you make a living from cold
and snow, in which case it's been miserable. Your time will come. After
one more day of near-record warmth today we cool off Thursday and
Friday. Expect highs mostly in the 30s next week. Above zero. Most of us
can live with that. ECMWF numbers: WeatherBell.
A Spring Fever-Less Start to March.
A return to more seasonable temperatures is imminent from the northern
Rockies and Upper Midwest into New England; relative warmth lingering
over the southern USA for the next few weeks. Expect more wintry
relapses in the coming weeks; I suspect winter isn't nearly done with us
yet.
Wet Winter Has Improved Colorado River Basin's Water Forecast, But The Drought Endures. Here's an update from
The Los Angeles Times: "...
Yet
there is one place where the precipitation has been particularly
welcome and could be transformative: the Colorado River basin, which
provides water to nearly 40 million people across seven states. “We’re
in a really good spot as far as snow accumulations,” said Malcolm
Wilson, who leads the Bureau of Reclamation’s water resources group in
the upper Colorado River basin. In fact, if the Rocky Mountains continue
to see substantial snowfall this winter, there is a chance that later
this year, water managers for the Colorado could do something that
seemed inconceivable just a few weeks ago: They could start giving water
away..."

California Braces For More Rain. How Bad Can It Get? Here's an excerpt from a story at
The New York Times: "...
This
latest storm is what’s called an “atmospheric river” — a weather event
more commonly known as the “pineapple express.” It is moist tropical air
from the central Pacific trapped in a band between different pressure
systems, Mr. Kurth said. When it hits California, it unleashes a high
amount of rain. “It’s like a fire hose of moisture when we get these
atmospheric rivers,” he said. An atmospheric river is not especially
unusual. “We usually get a couple every year,” he said. “On average we
get maybe three to five or so. This year we’ve gotten quite a few more.”
How many more? “More than a dozen prior to this one,” he said..."

Atmospheric Rivers Bring High Winds Too. Some surprising new research highlighted at
NPR: "...
Waliser
studied two decades of storms around the globe at mid-latitudes — that
is, outside the tropics. When he focused on the very windiest — the top 2
percent — he found that "atmospheric rivers are typically associated
with 30 and even up to 50 percent of those very extreme cases."
Atmospheric rivers were also responsible for almost that percentage of
the very wettest storms, too. But the windiness was surprising. Waliser
found that winds during an atmospheric river are typically twice the
speed of the average storm. He says emergency responders need to know
that. "Not only do [atmospheric rivers] come with this potential for
flooding hazards," he says, "they also come with potential for high
impact winds and extremes that can produce hazardous conditions..."

The Other "Big One". California's Pending Megaflood. Science fiction? Let's hope so, but waterlogged residents of California could endure something far worse. Here's an excerpt from
Curbed San Francisco: "...
The
results are similar to a hurricane, except they can last for weeks.
USGS tapped 117 “scientists, engineers, public-policy experts, [and]
insurance experts” to suss out what it would look like:
The Central Valley experiences flooding 300 miles long and 20 or more miles wide.
Serious
flooding also occurs in Orange County, Los Angeles County, San Diego,
and the San Francisco Bay Area. Wind speeds reach 125 miles per hour.
[...] Hundreds of landslides damage roads, highways, and homes. Property
damage exceeds $300 billion, most from flooding.
[...]
Agricultural losses and other costs to repair lifelines, dewater
(drain) flooded islands, and repair damage from landslides, brings the
total direct property loss to nearly $400 billion. Flooding evacuation
could involve 1.5 million residents.
In
all, 25 percent of the state could end up submerged. And the total cost
could surge as high as $725 billion—more than three times the estimate
of a mega-earthquake. $1.17 billion of that would be in San Francisco
alone..."

Fine, Water Doesn't Scare You? How About $10,000? The Weather Social
calls attention to the people who believe their vehicle can somehow
magically transform into a boat and get them safely to the other side of
a flooded road. Here's an excerpt: "...
In
all seriousness, you need to get to work and you need to earn your pay.
But if it’s really about collecting a paycheck, realize that driving
across a flooded road could set you back way more than a day or week of
pay. According to cartalk.com,
once water reaches the doors and the engine stalls, your wallet is
going to open up like a floodgate. Expect damage to carpets, floor mats,
door panels and the trunk liner. Seats and any motion mechanics or
sensors will need to be replaced. Water will get into the gas tank as
well and thus need drained. The brakes will need to be replaced.
Finally, the biggest issues will come from engine damage. Water in the
cylinders and transmission will need to be drained.
Especially when nobody is hurt, we regularly dismiss pictures of
stalled vehicles and say, “not me.” Especially when we’ve driven it
before, we regularly look at a flooded street and say, “I can make it...”
Coastal Cities Could Flood 3 Times a Week by 2045. Here's an excerpt from
Climate Central: "...
Washington
and Annapolis, Md. could see more than 120 high tide floods every year
by 2045, or one flood every three days, according to the study,
published last week in the journal PLOS ONE. That’s up from once-a-month flooding in mid-Atlantic regions now, which blocks roads and damages homes. “The flooding would generally cluster around the new and full moons,” said Erika Spanger-Siegfried,
a Union of Concerned Scientists analysts who helped produce the new
study. “Many tide cycles in a row would bring flooding, this would peter
out, and would then be followed by a string of tides without flooding.”
The analysis echoed findings from previous studies, though it stood out
in part because of its focus on impacts that are expected within a
generation — instead of, say, by the end of the century..."

The Age of the Giant Battery Is Almost Upon Us. So says
Bloomberg: "
The idea that giant batteries may someday revolutionize
electrical grids has long enthralled clean-power advocates and
environmentalists. Now it’s attracting bankers with the money to make it
happen. Lenders including Investec Plc, Mitsubishi UFJ Financial Group Inc. and Prudential Financial Inc.
are looking to finance large-scale energy-storage projects from
California to Germany, marking a coming-of-age moment for the fledgling
industry. The systems help utilities solve a longstanding clean-power
conundrum: managing the unpredictable output from wind and solar farms,
and retaining electricity until it’s needed. Battery costs have declined
40 percent since 2014 and regulators are mandating storage technology

Earth's "Technosphere" Now Weighs 30 Trillion Tons, Research Finds. That's the estimated weight of all the (crap) we've created, according to a new study highlighted at
The University of Leicester: "...
An
international team led by University of Leicester geologists has made
the first estimate of the sheer size of the physical structure of the
planet’s technosphere – suggesting that its mass approximates to an
enormous 30 trillion tons. The technosphere is comprised of all of the
structures that humans have constructed to keep them alive on the planet
– from houses, factories and farms to computer systems, smartphones and
CDs, to the waste in landfills and spoil heaps. In a new paper
published in the journal The Anthropocene Review, Professors Jan
Zalasiewicz, Mark Williams and Colin Waters from the University of
Leicester Department of Geology led an international team suggesting
that the bulk of the planet’s technosphere is staggering in scale, with
some 30 trillion tons representing a mass of more than 50 kilos for

Why We Need the EPA. Rivers are no longer catching on fire - that's probably a good thing, right? Here's an excerpt from

.A
collective memory lapse seems to have descended on lawmakers who seek
to dismantle an agency that has transformed American life for the
better. Since the EPA’s founding in 1970, concentrations of common air
pollutants, like sulfur dioxide, have dropped as much as 67 percent. The EPA helped mitigate catastrophes like acid rain, leaded gasoline, and DDT. The agency bravely classified secondhand smoke as a known carcinogen in 1993, paving the way for successful litigation against the tobacco industry and an incredible reduction in U.S. smoking rates...."

A Warning from Bill Gates, Elon Musk and Stephen Hawking.
It may not be an actual robot, but automation and AI will replace not
only blue-collar manufacturing jobs but many white-collar jobs as well.
It's already happening and America needs a plan to keep people gainfully
employed. Here's an excerpt from
Medium: "...
There’s a rising chorus of concern about how quickly robots are taking away human jobs. Here’s Elon Musk on Thursday at the the World Government Summit in Dubai:
“What
to do about mass unemployment? This is going to be a massive social
challenge. There will be fewer and fewer jobs that a robot cannot do
better [than a human]. These are not things that I wish will happen.
These are simply things that I think probably will happen.” — Elon Musk

Like
many extreme events, the Oroville emergency is a combination of natural
weather likely intensified by climate change. California regularly sees
“atmospheric rivers” that deluge the state with rainfall, but in a
hotter world, scientists anticipate that they’ll be amplified by an increase in the amount of water vapor in the atmosphere. Northern California is in the midst of its wettest rainy season on record – twice as wet as the 20th
century average, and 35% wetter than the previous record year. It

Researcher's 1979 Arctic Model Predicted Current Sea Ice Demise, Holds Lessons for Future. Here's a clip from
InsideClimate News: "
Claire Parkinson, now a senior climate change
scientist at NASA, first began studying global warming's impact on
Arctic sea ice in 1978, when she was a promising new researcher at the
National Center for Atmospheric Research. Back then, what she and a
colleague found was not only groundbreaking, it pretty accurately
predicted what is happening now in the Arctic, as sea ice levels break record low after record low. Parkinson's study,
which was published in 1979, found that a doubling of atmospheric
carbon dioxide from preindustrial levels would cause the Arctic to
become ice-free in late summer months, probably by the middle of the
21st century. It hasn't been ice-free in more than 100,000 years.
Although carbon dioxide levels have not yet doubled, the ice is rapidly
disappearing. This record melt confirms the outlook from Parkinson's
1979 model..."

The Alps Could Lose 70 Percent of Their Snow Cover by 2100.
Travel + Leisure has the details: "
The Alps
could lose up to 70 percent of their snow cover in the next century,

seen record low snowfalls over the past years, the trend is set to
continue and worsen, according to a study published in the European
Geosciences Union (EGU) journal The Cryosphere. In a best case scenario, if the Paris climate agreements are
followed, limiting the warming of the earth by 2 degrees Celsius (3.6
degrees Fahrenheit), the Alps will lose at least 30 percent of their
snow cover by 2100. If greenhouse gas emissions are not properly

Companies Are Concealing the Risks of Climate Change. So says a post at
Inverse; here's an excerpt: "...
Whatever
policy direction the SEC takes on climate risk, it is unlikely to deter
those investors who believe the present system of voluntary and
mandatory disclosure has failed to provide them with sufficient
information on the risks of climate change. And some market
participants, such as Bank of England Governor Mark Carney,
worry that the underreporting of climate change information is creating
a big risk for financial markets – a carbon bubble – that could lead to
a major market failure. Currently, the SEC requires mandatory
disclosure of all “material” information, while everything else is voluntary. This system has created a vast amount of publicly available information on the costs and risks of climate change..."

The Problems with Winter Warming. I'm
enjoying the extended streak of spring fever in February (!) as much as
everyone else, but at the risk of being Debby Downer there are some
downsides to spring coming extra-early. Here's a post from
Climate Central: "
The
decrease in winter cold effectively makes the winter shorter. While
that might sound good at first, it comes with consequences for
recreation, farming, and the environment. In colder climates,
winter-based recreational activities, like skiing, ice fishing, and
snowmobiling will become less prevalent. More disease-carrying insects,
like mosquitoes and ticks, will survive through a milder winter.
Declining snow pack leads to lower reservoir levels, providing less
water for irrigation of crops. Fruit trees, which need to become dormant
in the winter to blossom in the spring, may produce smaller yields.
Pollen counts will rise, which can trigger respiratory illnesses for
allergy sufferers."
Humans Changing Climate 170 Times Faster than Natural Forces. Yale Environment360 has a summary of new research: "
Humans are changing the climate 170 times faster than natural forces, according to a new study

research is the first mathematical equation to compare the impact of
human activity on current climate to naturally occurring changes. For 4
