Giving Thanks for Quiet Weather and a Mild Bias Into December

Giving Thanks For Quiet Weather

"When you arise in the morning, give thanks for the food and for the joy of living. If you see no reason for giving thanks, the fault lies only in yourself" wrote Tecumseh, a 19th century Shawnee Native American leader.

In spite of viral angst and economic malaise, the glass is much more than half full. Today I will choose safety over togetherness and avoid turning Turkey Day into a super-spreader event. I'll be giving thanks in my own way, reaching out to family, friends, preachers, teachers and mentors, thanking them for helping me along the way.

I'm also giving thanks for quiet weather. After a rowdy October November has been pretty quiet; 12th warmest at MSP and 5th warmest on record statewide, according to Dr. Mark Seeley.

The Doppler shall remain unplugged until further notice - no big storms brewing. After approaching 50F Saturday we cool off next week, before another Pacific-sweetened surge of 40s the second week of December.

We may pay for this in January. One day at a time.

Happy Thanksgiving!

Trending Milder Than Average. GFS (below) is more aggressive with a mild signal into early December than ECMWF (above) but both models show upper 40s Saturday, followed by a chilly slap Monday. I see more of a Pacific influence than a Canadian flow into at least the first half of December. Graphic: WeatherBell.

Turkey Day Climatology. The Minnesota DNR has some timely nuggets: "...The coldest Thanksgiving Day minimum temperature was 18 degrees below zero on November 25, 1880. The coldest high temperature was one below zero on November 28, 1872. The last time it was below zero on the morning of Thanksgiving was in 2014, with four below zero. 2014 had the coldest Thanksgiving high temperature since 1930 with a temperature of 10 degrees. Measurable snow fell on 29 of the past Thanksgivings back to 1884, about every five years or so. The most snow that fell on Thanksgiving was five inches in 1970. The last time there was measurable snow on Thanksgiving was in 2015 with 1.3 inches of snow. Historically, about one in three Thanksgivings have at least one inch of snow on the ground. The deepest snow pack is a tie with 1921 and 1983, both with 10 inches on the ground by Turkey Day. In 2019 there was seven inches of snow on the ground..."

Relatively Mild November. Dr. Mark Seeley has the details in Minnesota WeatherTalk: "The recent moderation in temperature looks to prevail through the Thanksgiving holiday until the end of the month. As such it is likely that November 2020 will end up falling among the 20 warmest Novembers in state history, quite a remarkable turn around from last month, when we recorded one of the coldest Octobers in history. For the year 2020 so far Minnesota has recorded 7 warmer than normal months and 4 colder than normal months. Overall, the year is tracking to finish as another warmer than normal year but by less than 0.5 degrees F..."

Record-Breaking 2020 Atlantic Hurricane Season Draws To An End. Good riddance. NOAA has highlights and lowlights: "The extremely active 2020 Atlantic hurricane season is drawing to a close with a record-breaking 30 named storms and 12 landfalling storms in the continental United States. While the official hurricane season concludes on November 30, tropical storms may continue to develop past that day. NOAA's seasonal hurricane outlooks accurately predicted a high likelihood of an above-normal season with a strong possibility of it being extremely active. In total, the 2020 season produced 30 named storms (top winds of 39 mph or greater), of which 13 became hurricanes (top winds of 74 mph or greater), including six major hurricanes (top winds of 111 mph or greater). This is the most storms on record, surpassing the 28 from 2005, and the second-highest number of hurricanes on record..."

2020 Joins List of 10 Most Extreme Atlantic Hurricane Seasons in Satellite Era. The Weather Channel has context: "The 2020 Atlantic hurricane season is now among the 10 most active seasons in more than five decades following Hurricane Iota's intensification into a Category 5 earlier this week. Since satellite detection began in the mid-1960s, Atlantic hurricane seasons have had as many as 30 named storms (2020) and as few as four (1983). Various factors in the atmosphere and ocean typically drive whether a given hurricane season is busy or relatively tame. But ranking the most extreme hurricane seasons isn't as simple as examining the number of tropical storms and hurricanes that occurred in a given year. We need to dig a little deeper to capture the full picture..."

Word Choice Matters in Weather Communications. It turns out getting the forecast right is only half the battle. Here's an excerpt of a press release from The University of Georgia: "...When a storm like Hurricane Zeta is heading for vulnerable shorelines, meteorologists and local officials need people to act fast. And the words they use when addressing the public can mean the difference between people getting to safety or trying to stick it out until it's too late. Words like "violent," "harsh," "wild" and "unpredictable" are more likely to make people feel helpless and out of control when faced with extreme weather, according to new research from the University of Georgia. And that might put them off from making rational safety precautions. "Certain words just pack emotional associations," said Alan Stewart, a professor in UGA's Department of Counseling and Human Development Services based in the Mary Frances Early College of Education. "It's important to find that middle ground where you alert the public and you empower them, but you don't overwhelm them..."

Lightning "Superbolts" Can Be 1,000 Times Brighter Than Ordinary Flashes. Some breaking news, courtesy of Capital Weather Gang: "...Earlier this year, researchers confirmed a pair of ultra-long-distance lightning strikes in South America that spanned up to 442 miles and lasted for nearly 17 seconds. Ongoing research has turned to how much power these fierce discharges contain, as well as their relative rarity. A new paper published in the American Geophysical Union's Journal of Geophysical Research: Atmospheres found that roughly one third of 1 percent, or 1 in every 300 lightning strikes, could be classified as a superbolt..."

Weather Service Tells Congress Radar Gaps Don't Hurt Warning Accuracy, But Outside Scientists Disagree. Doppler works best within 75 miles of the radar site, beyond that the curvature of the Earth makes it impossible for the radar beam to see what's really happening close to the surface. Here's an excerpt of a story at Capital Weather Gang: "...Now, an overdue report to Congress from the National Oceanic and Atmospheric Administration (NOAA), which operates the National Weather Service, attempts to quantify the impacts of such gaps on warning performance. The results downplay the significance of the gaps, counter to the experience of some public- and private-sector meteorologists. Several meteorologists said the congressionally mandated report inadequately addresses the true impacts of these gaps, describing its methodology as inadequate and incomplete and its conclusions as "disappointing" and even "offensive." The gaps, which the report identifies in some detail, occur in locations so far removed from radar sites that the beams emitted by the radar overshoot the weather they are intended to detect. The greater distance a location is from a radar site, the higher in the sky the radar scans for trouble..."

It's Official: Solar is the Cheapest Electricity in History. A story at Popular Mechanics caught my eye; here's a clip: "...In a new report, the International Energy Agency (IEA) says solar is now the cheapest form of electricity for utility companies to build. That's thanks to risk-reducing financial policies around the world, the agency says, and it applies to locations with both the most favorable policies and the easiest access to financing. The report underlines how important these policies are to encouraging development of renewables and other environmentally forward technologies. Carbon Brief (CB) summarizes the annual report with a lot of key details. The World Energy Outlook 2020 "offers four 'pathways' to 2040, all of which see a major rise in renewables," CB says..."

Electric Airplanes: Dreams of Electric Fleets. Will planes eventually become electrified and battery-powered. The challenges are daunting, but not insurmountable, reports Quartz: "...Weighed down by engineering challenges and without any big investments from airlines, electric flight has remained a quixotic experiment for decades. Now that's changing. Private companies have put in the research to overcome those engineering issues, building planes that cost and emit less, finally making electric airplanes attractive for airlines and feasible for the masses. By 2035, the aviation industry could be 25% electric or at least hybrid, the investment bank UBS estimates. If these companies are successful, they will eliminate a huge proportion of the direct emissions for most commercial aviation, in the process transforming how humans move around the planet. But to do that, these companies have to move their innovative planes from prototype to commercial runways to 30,000 feet—no small challenge..."

We're Celebrating Thanksgiving During a Pandemic: How We Celebrated During 1918 Flu Pandemic. USA TODAY reports that history is, in fact, repeating itself: "More than 200,000 dead since March. Cities in lockdown. Vaccine trials underway. And a holiday message, of sorts: "See that Thanksgiving celebrations are restricted as much as possible so as to prevent another flare-up." It isn't the message of Thanksgiving 2020. It's the Thanksgiving Day notice that ran in the Omaha World Herald on Nov. 28, 1918, when Americans found themselves in a similar predicament to the millions now grappling with how to celebrate the holiday season amid the coronavirus pandemic. "Every time I hear someone say these are unprecedented times, I say no, no, they're not," said Brittany Hutchinson, assistant curator at the Chicago History Museum. "They did this in 1918..."

Is This the End of College as We Know It? The Wall Street Journal (paywall) examines the trends and new options; here's an excerpt: "...For traditional college students, the American postsecondary education system frequently means frontloading a lifetime's worth of formal education and going into debt to do it. That is no longer working for millions of people, and the failure is clearing the way for alternatives: Faster, cheaper, specialized credentials closely aligned with the labor market and updated incrementally over a longer period, education experts say. These new credentials aren't limited to traditional colleges and universities. Private industry has already begun to play a larger role in shaping what is taught and who is paying for it. For more than a century, a four-year college degree was a blue-chip credential and a steppingstone to the American dream. For many millennials and now Gen Z, it has become an albatross around their necks..."

Henrik Fisker Wants to Lease You a No-Strings Electric Vehicle. A new way to lease vehicles with less down-side? Here's an excerpt from Business Insider: "...For about $3,000 up front and $379 a month, Fisker could lease you an Ocean and you could keep it or give it back, at your discretion, while also enjoying a generous, 30,000-mile annual allowance. That monthly payment is significantly lower than the $466 average reported by Experian for 2020. Furthermore, if the vehicle has been leased and returned, another customer could lease it, but at a lower cost. Rolled into the lease is a comprehensive service agreement, and Fisker said that the company is also trying to figure how to offer insurance that fits with the overall package and to reduce the cost of repairs..."

"Jingle Bells" Was Originally Written as a Thanksgiving Song. I did not know that, but a post at Mental Floss set me straight: "...Back in 1850 or 1851, James Lord Pierpont was perhaps enjoying a little holiday cheer at the Simpson Tavern in Medford, Massachusetts, when Medford's famous sleigh races to neighboring Malden Square inspired him to write a tune. The story goes that Pierpont picked out the song on the piano belonging to the owner of the boarding house attached to the tavern because he wanted something to play for Thanksgiving at his Sunday school class in Boston. The resulting song wasn't just a hit with the kids; adults loved it so much that the lyrics to "One Horse Open Sleigh" were altered slightly and used for Christmas. The song was published in 1857, when Pierpont was working at a Unitarian Church in Savannah, Georgia..."

November 26, 2001: A strong low pressure system develops in Colorado on the 25th, reached eastern Iowa during the evening of the 26th, then moved into eastern Wisconsin late on the 27th. It produced a wide swath of heavy snow across much of central Minnesota into West Central Wisconsin. Storm total snowfall of 8 inches or more was common, with a large area exceeding 20 inches. Specifically, Willmar picked up 30.4 inches, New London saw 28.5 inches, Collegeville had 23.4 inches, Litchfield and Granite Falls received 22 inches, and Milan had 20 inches. A convective snow band set up across this area on the 27th and remained nearly stationary for over 12 hours, resulting in the extreme storm totals. From 8 am on the 26th to 8 am on the 27th, Willmar received 21 of its 30.4 inches, setting a record for most snowfall in Willmar in a 24 hour period. The heavy wet snow downed numerous power lines, and at one point, at least 20,000 customers were without power in the Minneapolis-St. Paul metropolitan area. Over one thousand traffic accidents were noted across the entire area. Most were minor, but one accident claimed two lives when a car spun out and collided with a semi near Mora.

November 26, 1995: A narrow band of five to eight inches of snow falls from west central Minnesota around Canby and Granite Falls to east central Minnesota. This included much of the Twin Cities metro area.

November 26, 1965: A snowstorm develops across northern Minnesota. 14.7 inches of snow fell at Duluth, along with 13.6 inches at Grand Rapids.

Climate Stories...

A Thanksgiving Meditation in the Face of a Changing Climate. Here's an excerpt of an Op-Ed at the Scientific American Blog Network: "... Arguably, we don't know how to think about climate change because we've never really had to think about climate. It's always been a hum in the background, small variations around a mean that we take for granted. Now, that background note is growing louder and higher. Our climate is changing because of our actions. We can already see the impacts: changes in the range and behavior of animal species, coastal cities smashed by hurricanes and inundated by floodwaters, a haze of unseasonal wildfire smoke. Science says nothing about how to feel about these changes. I feel grief, guilt, anger, determination, hope, and sadness all at the same time. But what I feel more than anything is gratitude for what we have. We live on a medium-sized rock that goes around a garden-variety star in a galaxy that exists only because of a flaw in the smooth perfection of the early cosmos..."

How Biden Can Fight Climate Change Without Congress. Politico examines the possibilities; here's an excerpt: "...The Federal Reserve, the most powerful bank regulator in Washington, isn't waiting for Biden's inauguration. Even as Trump withdrew from the Paris climate agreement, the Fed quietly laid the groundwork to one day put its stamp on global regulatory standards for climate-related financial risks. This month, the Fed made a long-awaited announcement that it will seek to join the international Network for Greening the Financial System. The Fed also for the first time formally declared climate change as a potential danger to financial stability. The two steps were highly significant because the U.S. has been seen as falling behind other countries that have taken aggressive stances. Fed Chair Jerome Powell, a Trump (and Obama) appointee who will likely serve well into Biden's first term if not longer, said officials were obligated to incorporate the risks into how they think about the economy..."

Covid-19 and Climate Change Make Hurricanes More Devastating for Latin America. CNN.com reports: "After two Category 4 hurricanes this month, communities in these Central American countries have witnessed rivers overflowing from torrential rains, crops destroyed, cattle washed away, schools flooded, and roads engulfed in landslides. Death, disease and poverty will likely follow. While poor people in rural areas have been often worst-hit by the succession of Hurricane Eta and Hurricane Iota, the repercussions from those storms are already being felt in the halls of power. In Guatemala City this weekend, anger boiled up into the streets as protesters set fire to the Congress building, forcing legislators to reverse budget cuts to the country's already crippled health care and education systems. Exacerbated by the coronavirus pandemic, the fallout from these climate disasters will continue to spread. And it may eventually even reach distant countries, as Central Americans left desperate and vulnerable by the storms flee abroad..."

With John Kerry Pick, Biden Selects a "Climate Envoy" with Stature. Here's a clip from a New York Times explainer: "...On Monday, President-elect Joseph R. Biden Jr. said he would name Mr. Kerry his special presidential envoy for climate, creating a new cabinet-level position. In that role, Mr. Kerry will need to convince skeptical global leaders — burned by the Trump administration's hostility toward climate science and its rejection of the 2015 Paris Agreement — that the United States not only is prepared to resume its leadership role but will also stay the course, regardless of the Biden administration's future. "The United States' credibility on climate change has plummeted over the last four years," said Nicholas Burns, a Harvard professor and a former longtime State Department official who served Republican and Democratic administrations. He called Mr. Kerry's appointment a "powerful signal" that will help the United States, the world's second-largest greenhouse gas emitter after China, start regaining global trust on the issue..."

Slew of Rapidly-Intensifying Hurricanes Portends Trouble in a Warming World. Consistently warmer (deeper) water increases the potential for rapid intensification, as witnessed during the 2020 hurricane season which extended deep into November. Capital Weather Gang explains: "...Rapid intensification typically occurs in high-end hurricanes that reach Category 3 or above. Scientists now say this is happening more frequently, as storms are given a turbo boost from rising ocean temperatures. During the 2020 hurricane season, the waters of the Atlantic were unusually mild, the result of human-caused global warming superimposed atop natural climate cycles. The increase in rapidly intensifying storms is "not surprising," said Suzana Camargo, a hurricane researcher at the Lamont-Doherty Earth Observatory at Columbia University, because human-caused climate change is expected to increase the occurrence of these particularly dangerous storms, most prone to explosive development. According to Kerry Emanuel, a hurricane scientist at MIT, the 2020 Atlantic season provides a warning..."

A Record Hurricane Season is Ending. What Does Climate Change Have to Do With It? More perspective from PBS NewsHour Weekend; here's an excerpt of an interview: "...What that means for individual basins like the North Atlantic is a little bit harder to understand, in part because there are things like natural variability from year to year, right? But we do know our models do tell us that the storms are becoming more intense, both in terms of the the maximum wind speed, but also in the amount of rainfall. We expect about a 5 to 7 percent increase in rainfall within tropical cyclones, within hurricanes for every degree Celsius of warming that we have. And so if you see in the North Atlantic, right, if we were to flash forward 50 years in the North Atlantic is you know two or three degrees warmer than it is now, then you could start to expect upwards of over 10, maybe approaching 20 percent increase in tropical cyclone rainfall..."

Heat-Trapping Gas Levels Reach a New Record High, Despite Coronavirus Lockdown. CNN.com has details: "No, the coronavirus lockdown did not solve climate change. Not even a little bit. In fact, the concentration of greenhouse gases in the atmosphere surged to a new record high this year, even as the pandemic brought the world to a standstill, the World Meteorological Organization (WMO) said Monday. While carbon emissions fell during the spring lockdown, the drop amounted to little more than "just a tiny blip on the long-term graph" and will not have any meaningful effect on the atmospheric concentrations of greenhouse gases, the WMO said in its annual Greenhouse Gas Bulletin. Carbon dioxide and other greenhouse gases trap solar radiation in the atmosphere just like the glass traps heat in a greenhouse..."

A Warming Earth is Also a Wetter Earth. NOAA NCEI has the post; here's an exerpt: "...Simply put, precipitation amounts are increasing as temperatures rise because warm air holds more water vapor: a 1°F rise in temperature equals as much as a 4% increase in atmospheric water vapor. Other factors can contribute to rainfall, including El Niño and La Niña. Rain events are included in reports and assessments that look at changes in climate. Both the Fourth National Climate Assessment, issued in 2018, and the U.S. Global Change Research Program (USGCRP) Indicator Platform include heavy precipitation events as a chief topic. Big rain events have been methodically and more reliably reported since at least the 1950s, and patterns are changing. According to the USGCRP, most of the country has seen dramatic increases in big rain. "The biggest events are getting bigger, and big rain is taking up more of our annual rainfall budget," Arndt notes..."

More Frequent, Severe Climate-Fueled Disasters Exacerbate Humanitarian Crises. Scientific American reports; here's an excerpt: "...By combing through data on thousands of disasters the federation has responded to in the past decade, IFRC says that 83% of them were climate-related in some way, usually severe flooding, violent storms and deadly heat waves. "The number of such disasters triggered by extreme weather- and climate-related events has been increasing since the 1960s, and has risen almost 35% since the 1990s," the new report says. "These extreme weather- and climate-related disasters have killed more than 410,000 people in the past ten years, the vast majority in low and lower-middle income countries," IFRC says. "Heatwaves, then storms, have been the biggest killers..."

Climate Change is Making Winter Ice More Dangerous. The New York Times (paywall) has the story: "New research on the connection between climate change and winter drownings has found that reported drowning deaths are increasing exponentially in areas with warmer winters. The study, published on Wednesday in the journal PLoS One, looked at drownings in 10 countries in the Northern Hemisphere. The largest number of drownings occurred when air temperatures were just below the freezing point, between minus 5 degrees Celsius and 0 Celsius (between 23 degrees Fahrenheit and 32 Fahrenheit). Some of the sharpest increases were in areas where Indigenous customs and livelihood require extended time on ice. Across the countries studied, children under the age of 9 and teenagers and adults between 15 and 39 were the most vulnerable to winter drowning accidents..."

Burning Fossil Fuels Helped Drive Earth's Most Massive Extinction. The New York Times (paywall) has an eye-opening story: "...Paleontologists call it the Permian-Triassic mass extinction, but it has another name: "the Great Dying." It happened about 252 million years ago, and, over the course of just tens of thousands of years, 96 percent of all life in the oceans and, perhaps, roughly 70 percent of all land life vanished forever. The smoking gun was ancient volcanism in what is today Siberia, where volcanoes disgorged enough magma and lava over about a million years to cover an amount of land equivalent to a third or even half of the surface area of the United States. But volcanism on its own didn't cause the extinction. The Great Dying was fueled, two separate teams of scientists report in two recent papers, by extensive oil and coal deposits that the Siberian magma blazed through, leading to combustion that released greenhouse gases like carbon dioxide and methane..."

Study Finds Ticks Choose Humans over Dogs When Temperatures Rise. I had a sneaky suspicion, based on personal experience in recent years. The Guardian reports: "...but the stomach-churning scientific experiment has revealed that ticks carrying the deadly Rocky Mountain spotten fever (RMSF) disease are more than twice as likely to shift their feeding preference from dogs to humans when temperatures rise. The study, presentated at the annual meeting on the American Society of Tropical Medicine and Hygiene (ASTMH), observed whether the ticks, which use smell to seek out a host upon whose blood to feed, scuttled along a plastic tube towards the dog or the human..."
