39 F. high in the Twin Cities Monday at 6:24 AM.
34 F. average high on February 28.
20 F. high on February 28, 2015 (no leap day last year).
March 1, 1966: The Blizzard of ’66 hits Minnesota and lasts 4 days. Aitkin received 23 inches of snow. The snow depth at International Falls reached a record 37 inches by the end of the storm.
Atmospheric Autopilot – Spring Fling Next Week
Houston, we have a problem. We appear to have skipped a month this year. The calendar says March, but next week will feel like early April, with a string of 50s, even a few low 60s. Maybe a token thundershower or two to get you daydreaming about spring break?
In reality March 1 is the start of “Meteorological Spring”. The coldest 90 days of the year, historically, are behind us now. And what a benevolent winter it’s been. Based on NOAA heating degree data we’ve spent 17 percent less than average heating our homes since autumn of 2015.
Extended models suggest March may be 6F warmer than average, with a persistent warm signal spilling over into the Summer of 2016. Don’t fight the trends.
Today will be chilly but bright sun should help. Highs nudge 40F Saturday; 50s likely by Sunday. Next week looks mild and humid (new word) with a potentially soaking rain event by midweek. The snow may be gone, but frost in the ground may result in runoff problems and minor flash flooding if the rain falls too hard.
Ah, March. Coming in like a penguin – going out like a duck? I’m so confused.
So is the weather.

Peak Monday Wind Gusts. The sharper the differential in temperature the stronger winds have to blow to keep the atmosphere in a state of equilibrium. MSP and St. Cloud both experienced tropical storm force wind gusts yesterday; as high as 41 mph. Source: AerisWeather.
Temperature – Wind Plot. AerisWeather meteorologist D.J. Kayser plotted hourly temperatures and wind speeds (and gusts) yesterday for the Twin Cities, confirming that it was, in fact, unpleasantly blustery.
A Tale of Two Seasons. Winter is hanging on; NAM guidance hinting at a slushy inch of snow Wednesday night into early Thursday, then warming up over the weekend with 50s, even a chance of a 60F high next week. Showers and T-storms by Monday and Tuesday? I wouldn’t rule it out.
Fast-Forward Spring. GFS guidance confirms a significant warming trend next week with 60s by Tuesday, followed by slight cooling. Mid-April in early March? Looks like we’ll get another taste of temperatures nearly 30F warmer than average one week from today. Source: Aeris Enterprise.
Fluke or Trend? If you believe GFS guidance looking out 2 weeks it’s more trend than fluke. Another surge of 60s by mid-March is predicted. Not buying it again, but the trends have been consistent; swipes of chilly air but a definite mild bias to the maps.
Wednesday Night Slush Potential. Although NOAA NAM guidance shows the best chance of plowable snowfall amounts from the Quad Cities and Madison to Milwaukee late Wednesday into early Thursday the MSP metro may get brushed by a light, sloppy snowfall Wednesday night. 84-hour NAM accumulated snowfall forecast: NOAA and AerisWeather.
Flooding Potential Grows for West Coast. El Nino is fading fast, but the same MJO (Madden-Julian Oscillation) that helped to spin up a devastating cyclone for Fiji (Winston) is going to aim a firehose of Pacific moisture at the west coast. GFS guidance prints out some 5-10″ precipitation amounts from northern California into the Pacific Northwest over the next 10 days; avalanche potential for the coastal ranges and flash flooding and mudslides at lower elevations. Thanks to NCAR climate scientist Kevin Trenberth for helping me connect the dots on this one.
What March? The forecast for mid-March would be right at home in mid-April, a stormy trough sending a parade of storms into the Pacific Northwest and California; sparking a mild, Pacific-flavored flow for much of the lower 48. We’ll see a few more wintry outbreaks, but I predict an extra-early outbreak of spring fever.
Super Tuesday Tornadoes Were a 2008 Nightmare – And Storms May Strike This Time Around Too. Here’s an excerpt from Bustle: “…It has been more than eight years since the devastating storm system struck. A total of 87 tornados touched down over the course of the outbreak, which lasted more than 15 hours. Because it fell on such a politically important day, it has been named the Super Tuesday Tornado Outbreak. Polls had to close in Tennessee and Arkansas because of the dangerous conditions, and tornadoes also struck Missouri, Illinois, and Alabama, which were all holding primaries that day. Ten of the tornadoes were deadly, and five were classified as “violent” EF4 tornadoes on the Enhanced Fujita Scale, the new and improved measuring system instituted in 2007 but is very similar to the old F1 to F5 system…”

NOAA, University of Alabama – Huntsville and Partners Kick Off Tornado Study. The “VORTEX” project conntinues, focused on fickle, fast-moving tornadoes in the southeastern USA; here’s an excerpt at NSSL News: “…They will deploy approximately 13 vehicles, three mobile radars and one fixed radar from their operations base at the University of Alabama-Huntsville. During previous VORTEX field campaigns, researchers roamed the Great Plains, taking the instruments to the storms. This time, some of the instruments are stationary, and the domain is much smaller. As a result, the researchers expect to operate during four to five periods of several days each as the storms come to them. The number of killer tornadoes in the southeastern U.S. is disproportionately large when compared to the overall number of tornadoes throughout the country. Researchers believe this is caused by a series of physical and sociological factors, including tornadoes at night, in rugged terrain, as well as tornadoes occurring before the perceived peak of “tornado season,” during a time of year when storms typically move quickly. Other variables include the lack of visibility, inadequate shelter, and larger population density that increases the vulnerability of residents in this area…”

Ambitious Tornado Study Launches as Florida’s Tally Hits 28 This Year. Florida has already experienced 28 confirmed tornadoes in 2016, five times the normal number, to date? Here’s a clip from a story at PalmBeachPost.com: “…The so-called Dixie alley, which includes areas in Louisiana, Mississippi, Alabama, Arkansas and Tennessee, has more deaths on average per year than the more well-known tornado alley of the great plains where massive cyclones are often caught on camera. Florida, which has the third highest number of tornadoes on average per year nationally, will also be included in the study as researchers examine how tropical storms and hurricanes spawn tornadoes. The $5 million project, dubbed Vortex SE, comes following a tragic tornado outbreak last week that killed seven people along the Gulf Coast and in Virginia…”
“Are We Now The New Tornado Alley?” asks a writer at The Pensacola NewsJournal.
Move Over Snow Day. Is This The Era of “Tornado Days” for School Systems? Dr. Marshall Shepherd takes a look at what may be a growing trend, especially in southern states. Is it even a good idea? Here’s an excerpt of a story at Forbes: “During the last week of February, one of my University of Georgia doctoral students (also a meteorologist), Bradford Johnson, said,
They closed schools in Baton Rouge, Louisiana (his hometown) in advance of severe weather. I don’t remember that happening before.
An article from NOLA.com wrote,
Numerous schools and school systems in southeast Louisiana have canceled or curtailed classes Tuesday (Feb. 23) in advance of forecasted severe weather.
Are we in the era of the “Tornado Day” for school systems?…”
FedEx Driver Narrowly Swept Away by Tornado. Kyra deserves a raise. Here’s an excerpt from Huffington Post: “A Louisiana FedEx driver is lucky to be alive after harrowing surveillance video captured her narrowly being swept away by a powerful tornado while trying to seek shelter. Video taken outside of Saigon’s True Value Hardware in Paincourtville Tuesday shows Kyra Johnson running up to the store’s locked doors and frantically tugging on them to no avail. Seconds after she disappears off screen, the building’s roof and walls are seen flying into the parking lot like cardboard. The screen then goes black…”
Study Reveals Stunning Acceleration of Sea Level Rise. I suspect Minnesota’s lakes will look even better in the years to come; here’s an excerpt from Climate Central: “…A report published by Climate Central on Monday, the result of an analysis based in part on the findings in Monday’s paper, concluded that climate change was to blame for three quarters of the coastal floods recorded in the U.S. from 2005 to 2014, mostly high tide floods. That was up from less than half of floods in the 1950s. “I think this is really a first placing of human fingerprints on coastal floods, and thousands of them,” said Ben Strauss, vice president for sea level and climate impacts at Climate Central. Strauss led the analysis, which also involved government and academic researchers…”
As Sea Levels Rise, Economic Damage Piles Up Even Faster. Here’s a clip from Thompson Reuters Foundation: “…The Potsdam scientists said that mathematical models they developed to estimate rising costs would work around the world. “You can apply it in Tokyo, New York or Mumbai,” Kropp said. The exact costs of sea level rise, which could in the worst case reach about a metre by 2100, are extremely uncertain. One study in 2014 estimated it could cost anywhere from 0.3 percent to 9 percent of world gross domestic product a year by 2100. Jochen Hinkel of the Global Climate Forum in Berlin, the lead author of that study, said it illustrated vast risks but was based on the implausible assumption that governments would take no protective action…”

Unprecedented Scientific Report Says Bees and Other Pollinators Are In Dire Need of Help. The Washington Post reports; here’s a clip: “…An increasing number of pollinator species are thought to be in decline, threatened by a variety of mostly human pressures, and their struggles could pose significant risks for global food security and public health. Until now, most assessments of pollinator health have been conducted on a regional basis, focusing on certain countries or parts of the world. But this week, a United Nations organization has released the first-ever global assessment of pollinators, highlighting their importance for worldwide food and nutrition, describing the threats they currently face and outlining strategies to protect them…”

These Experts Say “Congress is Legislating Scientific Facts” – And Wrong Ones, Too. Here’s the intro to a Washington Post story: “A group of forest scientists, ecologists and climate researchers has sent a strongly worded letter to the U.S. Senate, arguing that pending bipartisan energy legislation incorrectly claims that burning trees for energy is carbon neutral. “Legislating scientific facts is never a good idea, but is especially bad when the ‘facts’ are incorrect,” say the researchers, led by Phil Duffy, president of the Woods Hole Research Center. “We urge you and other members of the Senate to reconsider this well-intentioned legislation and eliminate the misrepresentation that forest bioenergy is carbon-neutral...”
Utilities Move Ahead on Climate Despite Postponement. Is the proverbial writing on the wall, and the (smart) utilities are already going on the offensive, recognizing the inevitable? Fuel Fix has the article; here’s a link and story excerpt: “Despite the U.S. Supreme Court’s decision to put President Obama’s climate change initiative targeting power plants on hold, some of the country’s largest utilities are moving ahead to comply anyway. Executives from American Electric Power and Xcel Energy both said regardless of whether the president’s clean power plan holds up in court, they believe in the years ahead a federal crackdown on carbon emissions is coming. “We think there’s going to be some legal issues, but we’re still moving ahead to figure out the best way to comply,” Scott Weaver, manager of strategic policy analysis at AEP, said at the HIS CERAWeek conference in Houston Thursday. “Carbon regulation is not going away...”
Study: Fully-Automated Self-Driving Cars Could Actually Be Worse for Carbon Emissions. Here’s a snippet from a story at Vox: “…It stands to reason that vehicle automation could save energy and reduce emissions in some ways. Cars will be able to chain together more aerodynamically, drive at more consistent speeds, and perhaps serve as shared vehicles in lieu of individual vehicle ownership. But it also stands to reason that automation could increase energy use and emissions in some ways. If driving is easier and more pleasant, people will do it more. Automation will open up car travel to populations (the young, the elderly, the visually or otherwise impaired) who did not previously have access...” (Image: Shutterstock).
The “Oscars of Water” Honor The Best of Bottled and Tap. Are you a water connoisseur? Here’s an excerpt of a head-scratching story at Atlas Obscura: “The Oscars are upon us, but it’s not just movies that are being lauded. This weekend marks the 26th annual Berkeley Springs International Water Tasting—the self-proclaimed “Oscars of water.” Over 100 entrants, both corporate and municipal, will compete for the titles of Best Tap Water, Best Purified Drinking Water, and Best Bottled Water (Still and Sparkling). While it may not have an E! red-carpet pre-show, the event in Berkeley Springs, West Virginia, has become the longest running and most prestigious water tasting competition in the world, attracting participants from around the globe…”

Pilot Reveals Unsettling Reason Why Plane Lights Are Dimmed for Landing. New.com.au and The Sun has details: “…Dimming cabin lights before descent subtly prepares passengers to find their way to an emergency exit, especially when the aisle is illuminated. There are also health and safety reasons behind asking passengers to leave their blinds up before landing. By allowing more natural brightness into the aircraft, if the cabin lights cut off during a crisis, it is easier for passengers to see the path towards an emergency exit...”
How to Blend In Somewhere You Stick Out. You know, like Des Moines or Green Bay? Airfarewatchdog.com has a few good tips for power-travelers preparing for spring break; here’s an excerpt: “…Everyone sticks out somewhere. If you’re exploring a place where you don’t look like most of the other people, assume you’re doing this whole travel thing right. But there are benefits to blending in, too, even when your height, hair or skin color, gender, or other physical traits set you apart. Because really, how you look is only the most obvious way you’re standing out. There are plenty of other things—clothing, body language, social codes—that can help you blend in more, even if no one is ever going to mistake you for a local…”
Why Jean-Luc Picard Never Carried a Wallet. In fact I can’t remember any conversation of “money” on Star Trek. Will we outgrow the need for credit cards, someday, in a galaxy far, far away? Atlas Obscura wonders out loud: “…Saadia says this points to the fact that the final, post-economic society that is presented was a “policy choice,” more than a result of an increase in convenience. “It’s a matter of values and a democratic decision by society, rather than something that comes out of the natural outgrowth of technological progress,” he says. “Star Trek presents a post-economic future as a social choice.” The future promised by Star Trek may seem like an unattainable fantasy, but according to Saadia, we can start living it now to make it happen. “Being helpful, and transparent, and sharing is something that really matters in Star Trek,” he says. “You share the products of your work and you help other people do the same…”

Exxon Mobil’s Insane Argument Against Action on Climate Change. We can’t do anything about it so why bother? Sounds rational to me. Here’s an excerpt from Grist: “Exxon Mobil has devised a bizarre new argument to wriggle away from its shareholders’ demands: Humanity can’t fix the problem we created, so we shouldn’t even try. Yep — as it turns out, Exxon Mobil’s shareholders care a lot more about climate change than the company itself does. The planet’s largest publicly traded oil and gas company challenged a resolution about climate change regulations from its own shareholders on Friday, arguing that it’s a practical improbability that the emissions-restricting goals set forth by the recent climate accord in Paris will actually be achieved. Therefore, Exxon Mobil says, it shouldn’t have to address the impact that the regulations would have on its business…”

Dear Republicans: Climate Change Is, In Fact, Real (And Not a Religious Issue). Here’s an excerpt of an Op-Ed at The Winona Daily News: “…Sea levels are rising sharply, faster than at any previous point in the last 28 centuries. In just one example, in Annapolis, Md., from 1955 to 1964, there were 32 days of tidal flooding. From 2005 to 2014, there were 394 days of flooding. In the United States, this already is causing immense problems. Americans in a number of coastal towns are dealing with fouled drinking water, neighborhoods cut off from arterial roads for days at a time, flooded, muddy, moldy basements, ruined yards and houses that can’t be sold. Someday in the not-too-distant future, people will be astonished and appalled that millions scoffed at the idea that manmade carbon emissions had built up to such an extent that we badly damaged the entire earth and possibly killed a lot of our fellow humans…”
Inside Leonardo DiCaprio’s Crusade to Save the World. I give DiCaprio a lot of credit; he’s putting his money, effort and passion where his mouth is – trying to get the word out. Here’s an excerpt at Rolling Stone: “…Halfway between mother and maker, Leonardo DiCaprio is not unhappily marooned between the bright light of his own life – a looming Oscar, a personal fossil collection, a chauffeured rental Tesla – and the bleakness of the overheated world he inhabits with denialist Republicans and a Bangladesh coastline that could be nearly a quarter underwater by 2050. He wants us to move off fossil fuels entirely and wonders where we would be if we had spent billions on finding renewable energy sources rather than on the Iraq War…”
The Many Signs of Climate Change in the Far North. Newsminer.com has an interesting article from Fairbanks, Alaska – here’s an excerpt: “…Alaska’s thousands of glaciers are the resting place of snows that fell yesterday and many years ago. Those ribbons of ice worm along in trenches between mountains all over Alaska. Almost all of them are shrinking fast. After a few decades of continued study, glaciologists say this: During the last 20 years or so, Alaska’s glaciers melted as much as all of Antarctica’s glaciers (Antarctica is as large as eight Alaskas). Alaska glaciers added one-third as much water to the ocean as did Greenland’s ice sheet from 2005 to 2010. This is despite Alaska’s ice having 1/20th the area of Greenland’s. UAF’s Chris Larsen and many colleagues have made these calculations by measuring glaciers each year with instruments mounted on aircraft and satellites. Alaska’s extreme weight loss is showing up as sea spray in a storm topping a levee in New Orleans...”

Planet on the Ballot. Here’s an excerpt of a Paul Krugman Op-Ed at The New York Times: “…Many people, including some who should know better, still seem oddly oblivious to the ongoing revolution in renewable energy. Recently Bill Gates declared, as he has a number of times over the past few years, that we need an “energy miracle” — some kind of amazing technological breakthrough — to contain climate change. But we’ve already had that miracle: the cost of electricity generated by wind and sun has dropped dramatically, while costs of storage, crucial to making renewables fully competitive with conventional energy, are plunging as we speak. The result is that we’re only a few years from a world in which carbon-neutral sources of energy could replace much of our consumption of fossil fuels at quite modest cost...”
Warren Buffet is Wrong About Climate Change. Are the (true) costs being factored into the insurance equation? Here’s an excerpt of an Op-Ed at Huffington Post: “…Markets, governments and companies aren’t properly pricing the risk of climate change. For instance, are beachfront homes in low-lying areas as valuable as their owners believe? Experts reckon that only once markets and others attach a price to the threat of climate change will the rest of the world finally move to limit the potential consequences. If insurers — which must grow their assets in order to make good on their guarantees — measure the potential losses they could incur as a result of climate change, they can then price that risk. Then everyone else could follow. Buffett’s views against disclosure put him in sharp disagreement with Bank of England Governor Mark Carney, who has said that financial markets can help limit the effects of climate change, but only if companies — such as insurers — supply the kind of information that Buffett doesn’t want to disclose…”
Invasive Pest’s Winter Activity Possibly Linked to Climate Change. Phys.org has the story – here’s the introduction: “The early hatching of insect eggs from an invasive pest threatening millions of trees in the eastern United States may be linked to climate change, according to new findings from UT. Researchers Christy Leppanen and Daniel Simberloff recently found hemlock woolly adelgid eggs hatching in December – outside of their normal spring and summer life cycle. The discovery could shed light on why the pest is invasive and reveal why management efforts have failed. Until now, scientists have documented eggs hatching only from March through July...”

Arctic Warming: Why Record-Breaking Melting is Just The Beginning. When you hear scientists using terms like “absurdly warm” and “off our chart” you get a sense of the magnitude of warming observed at the top of the world; here’s an excerpt from The Independent: “…This year’s record low has been driven by what NSIDC calls an “absurdly warm” winter: its director, Mark Serreze, has described it as the strangest ever observed in the region. The US government’s National Oceanic and Atmospheric Administration says the warming is “off our chart”. In late December, temperatures within 200 miles of the North Pole actually peaked above freezing point. During January they averaged 13F above normal across the Arctic; even the coldest reading, recorded in Svalbard, north of the Arctic Circle, was warmer than the average highest temperature in previous years...” (Image: Climate Reanalyzer).
