Springing Forward Today - Are You Kidding Me? Plowable PM Snow Likely

21 F. high temperature in the Twin Cities yesterday.
39 F. average high on March 11.
66 F. maximum temperature on March 11, 2016.

March 12, 2009: The record low temperature for Minnesota for the month of March is set at -35. St. Cloud also sets a new daily record low of -15, breaking the previous record of -12 that was set in 1956. The high temperature in St. Cloud was also only 11 degrees on this date, which also set a new record for the low maximum temperature. This broke the previous record low maximum temperature of 12 degrees that was set in 1896.
March 12, 1990: The temperature at the Minneapolis-St. Paul International Airport hits a record-setting 69 degrees.



Springing Forward Into a Plowable Sunday Snow

Up is down. Left is right. It rained on Christmas Day and now, a little more than a week before the spring equinox, we'll see plowable snow. A late-season sucker-punch of winter isn't unusual for March, when all 4 seasons are conveniently packaged into one manic month. Then again Old Man

Winter never leaves willingly. He's like the clueless uncle who doesn't know when it's time to say goodbye.

It'll be like learning to drive on snow all over again. The last the metro area picked up a lousy inch was back on January 25. Really. Today's clipper will spread snow into town by afternoon; with air temperatures in the mid-20s even freeways will become snow covered. I'm still thinking 2-5 inches, with heaviest amounts south of the Minnesota River. Give or take a foot.

This same swirl of energy and moisture will fortify a coastal storm capable of a foot or more of snow from New York City to Boston on Tuesday.

A high sun angle melts most of our snow by Thursday. 40s return by late week; maybe 50s a week from Monday.

Chirping birds and green lawns are about 2-3 weeks away. Really!

Heaviest Snow Bands Set Up South/West of MSP. A plowable snowfall is still likely for most of the MSP metro area, but the heaviest amounts come over the far southern and southwestern suburbs, where some 6-8" amounts are possible. A 2-5" snowfall is expected in the metro by Monday morning, with the best chance of 5" toward Lakeville and Chaska. Map: Aeris AMP.


European Guidance. The ECMWF solution is in line with NOAA models, showing a 2-5" range across the Twin Cities metro, maybe an inch from Brainerd to Duluth. Travel conditions will get progressively worse south and west of MSP this afternoon and tonight. Map: WeatherBell.


NAM Solution. NOAA's 12 KM NAM is consistent with guidance from ECMWF and GFS, also keeping the heaviest amounts just south and west of the Twin Cities. With air temperatures in the low to mid 20s even freeways will become snow-covered, especially after dark this evening. Leave more time to get around later today: Snowfall prediction: NOAA and Tropicaltidbits.com.


Blizzard Watch New York City and Long Island to Boston. Much of coastal New England is expecting blizzard conditions by Tuesday (sustained winds over 35 mph with visibility under 1/4 mile in falling/blowing snow). Travel may come to a standstill from late Monday into Wednesday midday.


European Model Shifts Heaviest Snow Bands East. The 12z Saturday run of ECMWF pushes the most extreme snows from D.C. to New Jersey and Cape Cod, with significant amounts for Philadelphia and New York City. We'll have to see if this eastward nudge is a fluke or a true trend in model runs. Source: WeatherBell.


GFS Guidance. NOAA's GFS model prints out a 1-2 foot bulls-eye from near Washington D.C. and Baltimore to Philadelphia, another smear of extreme snows near Boston. I keep asking myself what can go wrong. A storm track closer to the coast could mean a period of rain/ice mixing with heavy snow, which would keep final amounts down. But there's now little doubt that much of the Northeast will see the biggest blast of winter snow and wind of the season within 48 hours.

Winter Relapse - Spring Fever Returns in a Week. Old Man Winter throws his weight around later today and Monday morning, but the sun is too high in the sky for the cold and snow to linger for long. This won't be like a January snowfall. 40s return late week; ECMWF guidance showing low 50s early next week. Graphic: WeatherBell.

Mild Finish to March. It may be hard to comprehend over the next 96 hours from the Upper Midwest to New England and the Mid Atlantic region, but milder, Pacific winds return within 1-2 weeks with 50s returning from the Midwest to the Northeast, meaning a rapid meltdown in the days to come. After a brief quiet spell the storm parade returns to California. What a shock.

California Storms: Wettest Water Year, So Far, in 122 Years. The Mercury News has details of a stunning meteorological turnaround: "Fueled by a parade of “Pineapple Express” storms, California is in the midst of its wettest water year in 122 years of record-keeping, according to federal scientists. Between October 2016 and February 2017, California averaged 27.81 inches of precipitation, the highest average since such records began being kept in 1895, according to data released Wednesday by the National Centers for Environmental Information, part of the National Oceanic and Atmospheric Administration..."


When is a Drought Over? A Wet California Wants to Know. Here's a clip from The New York Times: "...In Northern California, snow could be seen on top of Mount Diablo outside San Francisco last weekend. Across the state, dams are under siege and reservoirs are overflowing. The snowpack in the Sierra Nevada — a source of water once winter ends and the dry months settle in — was nearly twice its normal level last week. (And that was before even more snow arrived.) Yet for all that, California is, at least officially, still in a drought state of emergency. That has been the case since Jan. 17, 2014, when Gov. Jerry Brown issued the order after one of the driest years in California history. Why hasn’t the drought been declared over? Here are some answers for Californians — and everyone else who has watched this story unfold — about what is going on..."

Battered by Winter Storms, Big Sur is Cut Off from California. This is really quite amazing, and I had no idea the extent of disruption. Check out the jaw-dropping details in The Mercury News: "Isolated residents of this breathtaking coastal retreat are surviving through stockpiled food, airlifts and cooperation after this wild winter’s storms have cut off Big Sur, buckling a bridge and burying the asphalt along America’s most picturesque highway. One key bridge could be out of service for a year. Instead of the rich and famous dropping by for spa treatments at the Post Ranch and Ventana Inn, helicopters are dropping supplies to about 450 remaining residents of this glorious ZIP code. The community has turned to self-governing; there’s no law enforcement, elected officials, public services or tourists. For three weeks, Big Sur has not only been cut off from California — it’s also been cut in half...."

Hurricane Forecasters Sent a Blunt Warning to their Bosses. Andrew Freedman at Mashable has a post detailing growing concerns about the latest upgrade to the GFS, the Global Forecast System, NOAA's premiere (global) weather model. Apparently it doesn't do as well predicting hurricane track and intensity. In this case "upgrading" could mean a step backwards for meteorologists and the public.

Tornado Count. These numbers are from the Minnesota State Climate Office, not NOAA SPC. For the record "average" number of tornadoes, statewide, since 1950 is 36.

"Weather Microphones" Could Prevent More Deaths from Severe Storms. I had no idea there was such a thing as a tornado-detecting microphone. WRCB-TV in Chattanooga set me straight: "After the April 2011 severe weather outbreak, we learned that tornadoes behave differently in the South than in the plains. Researchers at the University of Mississippi's National Center for Physical Acoustics have developed low-cost, high-fidelity technology that could help better detect tornadoes by using special microphones. "These are microphones designed primarily for very low frequency sound, frequencies below what humans can hear," explains Senior Research Scientist Dr. Roger Waxler. Most of us can't hear sounds below 20 Hertz. But studies have proven that tornadoes emit frequencies much below this level from as far away as 20 miles because they're less prone to interference than high frequencies. These sound waves have been picked up by the microphones in western states. "There's a focus now to look at the Southeast both because of the tornado damage that's been done and also because it's hilly," adds Waxler. "It's a different environment..."

Floods and Hurricanes Predicted with Social Media. Predicted may be a strong word, but there is little doubt that social media has become a mirror, reflecting what's on our minds - and what we're talking about. Confirmation from new research highlighted at Science Daily: "...The researchers tracked photos and videos with tags such as river, water and landscape on the social media platform Flickr between 2004 and 2014. Whilst these words can be used to generally describe natural scenery, researchers found that in certain time periods before the peak of extreme weather events -- and in the locations where they occurred -- these words took on a distinct meaning of forecast and warning, showing the weather worsening. These risk-signalling words can act as 'social sensors', which when used alongside physical meteorological sensors can help to improve the prediction and monitoring of the behavior and severity of an evolving weather event in multiple areas..."

Facebook is Eating the World. If you don't have a few pangs of concern about the long-term impact of social media you're probably not paying attention. How, in an age of personalizied news bubbles, do we maintain an informed electorate? Here's a clip from Columbia Journalism Review: "...We are seeing huge leaps in technical capability–virtual reality, live video, artificially intelligent news bots, instant messaging, and chat apps. We are seeing massive changes in control, and finance, putting the future of our publishing ecosystem into the hands of a few, who now control the destiny of many. Social media hasn’t just swallowed journalism, it has swallowed everything. It has swallowed political campaigns, banking systems, personal histories, the leisure industry, retail, even government and security. The phone in our pocket is our portal to the world. I think in many ways this heralds enormously exciting opportunities for education, information, and connection, but it brings with it a host of contingent existential risks. Journalism is a small subsidiary activity of the main business of social platforms, but one of central interest to citizens..."

Best Weather Podcasts. Here's a post to get you started: "If you’re interested in learning more about weather and the weather enterprise – especially while driving, exercising or doing anything else when you might listen to music or an audio book – a number of weather-related podcasts might be worth your time. A podcast is basically a radio talk show that you can play on a web browser or download to a portable device like a smartphone or mp3 player for playback at your convenience. Some smartphone apps will automatically download a podcast’s new episodes when they become available. Several interesting podcasts are devoted to weather and often cover topics related to severe weather. Below, I list a few I’ve listened to and found to be worth my time..."


How to Clear a Path Through 60 Feet of Snow, Japanese Style. I can't help but feel a little jealous, although some of the ski resorts in the Sierra Nevada range in California may be telling similar snowy tales. Here's an excerpt from Atlas Obscura: "...The height of the canyon’s snow walls can reach a staggering 66 feet. Using another New York City analogy, that would leave your average five-story East Village walkup apartment building buried head to toe in snow. “The amount of snow that falls here is just exceptional,” says Yoshihide Tanikawa, Vice President of the Toyama Prefectural Road Public Corporation, which is in charge of snow plowing across many parts of  Toyama Prefecture, including the Snow Canyon. The reason behind the tremendous snowfall is a confluence of geography and meteorology. “Toyama is on the coast with an elevation of zero,” explains Tanikawa, and just 20 miles from the ocean is Mt. Tateyama. “So the altitude rises from sea-level to 3,000 meters [9,843 feet] in a very short distance...”

But it’s all about the Benjamins, Georgetown Mayor Dale Ross told NPR. “It’s our love of green — green rectangles and green energy,” he said, the rectangles signifying dollars. “First and foremost it was a business decision.” There was never any talk of global warming or climate change during the city’s deliberations in 2012 about its power source going forward. “I don’t think they’re ever going to accuse Georgetown of being the next Berkeley,” Ross told NPR’s Ari Shapiro. The city realized that there was enough wind and solar power available, that it was fairly predictable and that the prices wouldn’t fluctuate as much as oil and gas prices..."

Solar-Powered Everything. Charging up your cell phone with a solar-powered jacket? Why not. Here's an excerpt from NexusMedia: "...Touhey and his partners have collaborated with Tommy Hilfiger to make solar-powered jackets, and now they’re working on a line of bags with built-in solar panels. While coats can’t generate nearly as much power as larger arrays, every person with a smartphone is a potential customer. “It’s really cool to plug in your phone and charge it with the sun,” says Touhey. Researchers are developing woven solar fabrics that have photoactive dyes coating individual threads, so each fiber is a miniature solar panel. But for now, flexible solar panels must be laminated on top of fabrics..."

Even If Symbolic, Chicago Fossil Fuel Divestment Could Send "Powerful Signal". Here's a clip from Midwest Energy News: "...Chicago is often touted as a leader on this front thanks to its solar, energy efficiency and other programs, along with the 2012 closure of two urban power plants and city officials’ action against petroleum coke storage. Now a majority of City Council members and the Chicago chapter of 350.org want the city to make a statement against the fossil fuel industry by pledging to divest the city’s pension funds and stocks and bonds. A divestment resolution was introduced in December, and backers are hoping it will be heard by the full council this spring. The measure would be largely symbolic, since a resolution is non-binding and the state government is in charge of pension investments. But supporters say that the resolution would send a powerful message and could be followed by a city ordinance that might mandate some divestments..."

How Delta Landed on the 100 Best Companies To Work For List. Treat employees as owners (profit sharing, stock options) and amazing things happen. Kudos to Delta to restoring my faith in American air carriers; here's an excerpt at Fortune: "The next time you have a bad day at work, imagine you’re instead in an airport surrounded by hundreds of frustrated customers demanding to know when they’ll get home. Or try ­explaining an unexpected layover to a plane full of grumpy passengers. That sort of pressure is why the airline industry is among the most stressful of work environments. But in the case of Delta Air Lines (dal, +0.08%), many employees don’t just tolerate their jobs. They love them.Among the companies that made the cut for Fortune’s 100 Best Companies to Work For list, the most surprising may well be Delta, which is on the list this year for the first time; it’s also the first airline to make the cut in a dozen years..."

Harvard Theoriests: How Sailing Aliens Could Have Caused Fast Radio Bursts. Maybe aliens will take our minds off more pressing issues. Here's an excerpt from The Washington Post: "In 2007, a West Virginia University astrophysicist named Duncan Lorimer detected a brief yet intense signal while combing through archival data from the Parkes Observatory telescope in Australia. The signal was quick. The spurt of radio activity, originating from a source other than our galaxy, lasted fewer than 5 milliseconds. And it was furious. To generate such a burst would require 500 million times the power of our solar system’s sun. The unknown source of the signal prompted intense speculation. One proposal, to be published in Astrophysical Journal Letters, may be the wildest yet: Sailing aliens. “An artificial origin is worth contemplating and checking,” said Avi Loeb, a theorist and author of the paper at the Harvard-Smithsonian Center for Astrophysics, in a statement on Thursday..."

Daddy's Working! Best. Interview. Ever. Check out details of a very funny (and authentic!) BBC interview, courtesy of Daily Mail Online: "Live television always leaves room for hilarious gaffes - which is exactly what happened when a BBC debate on South Korea was interrupted by the interviewee's children.  The hilarious footage shows expert Robert Kelly, an associate professor of Political Science at Pusan National University in Busan, handling serious questions on the country's president, Park Geun-hye, being ousted from power.

Climate Stories....



How We Know that Climate Change is Happening - and that Humans are Causing It. Popular Science has a post worthy of your time; here's an excerpt that caught my eye: "...Arndt and his colleagues spend their days poring over data, comparing the incoming numbers to the baseline they call “normal.” Using daily, weekly, monthly, and annual rhythms, they coordinate data collection and sharing, keeping an eye on the quality of the numbers and how they stack up compared to yesterday, last week, and longer. For Arndt, climate is all about scale—and the information that passes through his office tells a story that’s become all too familiar. “The upper atmosphere is cooling while the lower atmosphere is warming,” he says. “You don’t get that without changing the composition of the atmosphere. We’re seeing changes you would theoretically see in a warming world. More big rain—that’s an expectation. More big heat—that’s an expectation. The frozen stuff is generally melting or going away, based on the time of year and the location on the planet.” He pauses for a moment, then continues. “I think the basics are more than settled...”

Carbon Dioxide Levels Rose at Record Pace for Second Straight Year. Here's an excerpt of an update from NOAA: "Carbon dioxide levels measured at NOAA’s Mauna Loa Baseline Atmospheric Observatory rose by 3 parts per million to 405.1 parts per million (ppm) in 2016, an increase that matched the record jump observed in 2015. The two-year, 6-ppm surge in the greenhouse gas between 2015 and 2017 is unprecedented in the observatory’s 59-year record. And, it was a record fifth consecutive year that carbon dioxide (CO2) rose by 2 ppm or greater, said Pieter Tans, lead scientist of NOAA's Global Greenhouse Gas Reference Network. “The rate of CO2 growth over the last decade is 100 to 200 times faster than what the Earth experienced during the transition from the last Ice Age,” Tans said. “This is a real shock to the atmosphere...”

Earth's Oceans are Warming 13% Faster Than Thought, and Accelerating. Climate scientist and University of St. Thomas professor John Abraham writes for The Guardian; here are a couple of excepts from a recent post: "...Fortunately, a paper just published today in Science Advances uses a new strategy to improve upon our understanding of ocean heating to estimate the total global warming from 1960 to 2015. I was fortunate to co-author the study, which uses several innovative steps to make improvements...We were able to extend our techniques back to the late1950s and show that the rate of global warming has changed significantly in the past 60 years. One main outcome of the study is that it shows we are warming about 13% faster than we previously thought. Not only that but the warming has accelerated. The warming rate from 1992 is almost twice as great as the warming rate from 1960. Moreover, it is only since about 1990 that the warming has penetrated to depths below about 700 meters..."

What Slashing the EPA's Budget by One-Quarter Would Really Mean. InsideClimate News takes a closer look: "...With cuts on that scale, EPA would have to function with resources comparable to its earliest years, shortly after its founding under Richard Nixon. That was before the rise of the Superfund toxic dump cleanup program in 1980, the revisions to the Clean Air Act that in 1990 created economy-wide pollution permitting, the changes to the Safe Drinking Water Act that passed Congress overwhelmingly in 1986, and the growing complexity of dealing with pollution from pesticides, dioxins and other chemicals. "I believe EPA has been run on a shoestring for a long time," said Bruce Buckheit, a former EPA lawyer who worked on pollution enforcement, a central task for the agency. "You're past the point where you have fat to cut..."


EPA Head Scott Pruitt Says Carbon Dioxide is not a "Primary Contributor" to Global Warming. Amazed that basic science is still being misunderstoon and misrepresented in 2017; here's an excerpt from PolitiFact: "...The normal environment of the earth is that several types of gas stick in the atmosphere and trap excess heat, including carbon dioxide, water vapor, methane and nitrous oxide, making a natural "greenhouse." Since the Industrial Revolution in the early 1800s, humans have changed the composition of the greenhouse — leading to climate change — by releasing significant amounts of carbon dioxide into the air primarily through burning fossil fuels. "Pruitt is incorrect. CO2 is a primary contributor to global warming. That fact is not in dispute among climate scientists," said Anne Slinn, executive director for research of the Center for Global Change Science at the Massachusetts Institute of Technology. This chart from the National Oceanic and Atmospheric Administration shows that even though the earth has experienced fluctuations in carbon dioxide levels throughout its history, there’s more carbon dioxide now than there has been in at least 400,000 years..."

Tweet Storm! NASA's Gavin Schmidt vs. Scott Adams. Yes, you still have the freedom to be willfully ignorant. Here's an excerpt of a fairly amazing tweet string as Schmidt tries to argue that the climate is, in fact, changing and we are responsible, via Twitter - courtesy of Storify: "So Gavin Schmidt wrote 42 tweets to Scott Adams about the state of climate research. I made it into a Storify because it's a nice summary of where "we" are. I wonder about the signicance of the number 42..."

Chevron Says Climate Risks Pose Minimal Risk to Operations. The Wall Street Journal reports: "Chevron Corp. said in a new report that a global transition to lower-carbon energy sources poses a minimal risk to its operations, a response that follows growing shareholder demand for more disclosure on climate risks. Dramatic global action to limit the effects of warming temperatures wouldn't harm Chevron’s assets because the oil giant is investing in lower-cost opportunities, according to the report, which was quietly posted on the company’s website Wednesday evening. Such a scenario could render costlier projects uncompetitive, the company said..."

"We Thought We Would Hit Your Sweet Spot." Don't underestimate the power of entrenched monopolies and their ability to sway politicians and media. Change is always hard, and the fossil fuel industry does not want to be disrupted anytime soon. Here's an excerpt from a recent Wall Street Journal Op-Ed: "...It’s hard to believe that the editorial board of The Wall Street Journal would oppose a conservative, free-market, revenue-neutral, limited-government, internationally competitive approach to the potential threat of climate change that would eliminate the heavy hand of government regulation by the EPA—and is supported by many of America’s major oil- and gas-producing companies. But that’s exactly what the board did in its Feb. 25 editorial “The Carbon Tax Chimera.” The Journal, whose sage editorial writing we have admired over the decades, lists several problems with our proposal for a levy on carbon that would not grow government, but instead would be returned to all Americans in the form of a dividend of the revenues raised. Some of the Journal’s concerns are speculative while others are just flat wrong. But more important, the editorial criticizes an approach supported by some of the very industries that would pay the proposed levy..."
