The Importance of Volunteer Weather Observations
America experiences more severe weather than any nation on Earth. New technology (satellites, Doppler, computer simulations) are impressive, but there’s no substitute for ground truth; knowing what is happening now – the current weather. Airport observations are good and reliable, but the National Weather Service still relies on a network of 11,000 NOAA NCDC COOP volunteer observers who monitor weather in their yards every day.
There’s good precedent for this. Thomas Jefferson bought his first thermometer while writing the Declaration of Independence; he maintained a nearly unbroken record of weather observations until 1816. George Washington alsokept track of weather; the last weather entry in his diary was made the day before he died.
The sun makes a cameo appearance today, but the approach of a warmer, stickier front sparks spotty
airmass T-storms Wednesday into Friday. Some towns may pick up impressive rains, other towns nearby much less. Sunday and Monday look dry withdaytime highs well up into the 80s.
Models hint at a tropical depression, or even “Alberto” brushing New Orleans by this Saturday. Stay tuned.
So You’re Telling Me I Have a Chance? With all credit to “Dumb and Dumber”, there’s at least a chance that T-storms may drop locally heavy rain Wednesday into Friday. The best chance of significant rain, according to NOAA GFS-FV3 will come across parts of central and southwestern Minnesota, where some 1″+ amounts are predicted. We’ll see. I suspect we’ll see highly variable amounts – some farms will get a nice watering while others (a few miles away) see little or nothing. Such is the case with summer convection.

Flirting with 90F? I wouldn’t be one bit surprised to see MSP highs hitting 90 degrees for the first time in 2018 as early as Saturday; again Monday and Tuesday of next week. ECMWF for the Twin Cities: WeatherBell.
Hot Start to June? Confidence levels are low this far out (they always are) but yesterday’s 2-week GFS “trend” suggests a hot time of it the first week of June from the Desert Southwest across the Plains and Midwest to the East Coast.
Dry Spell Deepens. According to the U.S. Drought Monitor 53.46% of Minnesota is abnormally dry and 6.47% of state is under moderate drought. Bring Me The News reports: “…Drought conditions are the result of “increasingly dry conditions over the past 60 to 90 days,” says the USDA’s Eric Luebehusen. Central and northern Minnesota are running 25-60 percent below normal precipitation for this time of year, which the Twin Cities office of the National Weather Service says is about 1-2 inches of rain below normal...”
How Volcanologists Predicted Kilauea’s Explosive Eruption. WIRED.com explains: “…It’s been a testing ground for monitoring equipment, and not only are new techniques developed there, but the network of equipment has been expanding for decades.” The scientists at HVO has been very on point for this ongoing, slow-boil eruption. As the geoscientist (and former WIRED blogger) Erik Klemetti wrote in his blog at Discover, months ago the HVO scientists predicted vents opening in the East Rift zone, farther away from the summit than they usually appear, based on inflation under an area called Pu’u O’o. They predicted, accurately, that the development Leilani Estates was in danger, and Tuesday night USGS classified Kilauea as a code-red eruption risk…”
As Cities Sprawl, More Texans Are Exposed to Tornadoes. What was farmland 10-30 years ago has transformed into subdivisions and neighborhoods, increasing the probability of tornado-related damage, according to The Texas Tribune: “…Texas’ population has grown faster than any other large state’s this decade. It’s been the nation’s growth center and has shown no signs of slowing down, according to Steve Murdock, former director of the U.S. Census Bureau. For Fox, this means the tornadoes that he’s spent his whole career tracking can destroy more lives than ever before. Some suburbs around Dallas and Fort Worth have doubled in size over the past 20 years. Others have tripled. To accommodate additional residents, new housing developments and businesses have sprung up in multiple cities. As a result, the recipe for disaster that Fox fears has already begun, as tornadoes have struck densely populated communities that simply didn’t exist a few years before…”

Thomas Jefferson and the Telegraph: Highlights of the U.S. Weather Observer Program. A story from NOAA had some very interesting nuggets: “…The earliest known systematic weather observations in America were taken by John Campanius Holm along the Delaware River in the 1640s. Some of our earliest presidents also were avid weather observers. Thomas Jefferson bought his first thermometer while writing the Declaration of Independence, and purchased his first barometer a few days following the signing of the document. Jefferson maintained an almost unbroken record of weather observations until 1816. George Washington also took regular observations; the last weather entry in his diary was made the day before he died. During the early and mid-1800’s, weather observation networks began to grow and expand across the United States. The Surgeon-General of the Army issued a directive to his Army surgeons in 1818 to record the weather and everything of importance relating to the medical topography of his station, the climate, and diseases prevalent in the vicinity. This was to help determine if there was a cause and effect relationship between climate and the health of the soldiers and to determine the occurrence of any change in the climate of a given district over time…”

Reforming the National Weather Service, Part 1: Changing the Role of Human Forecasters. In a day and age of model ensembles is there still a place for human forecasters? Cliff Mass has some interesting data and food for thought; here’s an excerpt of a recent post: “…Humans are needed as much as ever, but their roles will change. Some examples:
1. Forecasters will spend much more time nowcasting, providing a new generation of products/warnings about what is happening now and in the near future.
2. With forecasts getting more complex, detailed, and probabilistic, NWS forecasters will work with local agencies and groups to understand and use the new, more detailed guidance.
3. Forecasters will become partners with model and machine learning developers, pointing our problems with the automated systems and working to address them.
4. Forecasters will intervene and alter forecasts during the rare occasions when objective systems are failing.
5. Forecasters will have time to do local research, something they were able to do before the “grid revolution” took hold…”
For Emergencies, Hope Isn’t a Plan. Some very good advice from the Minnesota Department of Public Safety; here’s an excerpt of a post: “None of us can see the future, so it’s impossible to know if and when an emergency will occur. But simply hoping a disaster won’t happen won’t help you survive and recover when it does. Hope is good, but it’s not a plan. So when something happens like the April 26 fire at the Husky Refinery in Superior, Wisconsin, you need to be ready. There are two refineries in the Twin Cities area—one in St. Paul Park, and another on the border of Rosemount and Inver Grove Heights. Minnesota is also home to two nuclear generating plants as well as many other types of facilities that use hazardous materials. So if you live near one, you need to have an emergency plan. The people of Superior didn’t know when they left for school and work that morning that they would have to evacuate their homes before the end of the day. But it’s safe to say that those who had emergency kits packed, a family emergency communications plan in place, and who knew where to take temporary shelter had an easier time of it. Put simply, you can’t make those kinds of decisions when you have minutes to evacuate your home…”
NOAA GOES-17 Shares First Light Imagery from Geostationary Lightning Mapper. The lightning imagery is fairly mind-boggling; here’s a clip from a NOAA post: “…The Geostationary Lightning Mapper onboard GOES-17, like the one on board NOAA GOES East, is transmitting data never previously available to forecasters. The mapper observes lightning in the Western Hemisphere, giving forecasters an indication of when a storm is forming, intensifying and becoming more dangerous. Rapid increases of lightning are a signal that a storm may strengthen quickly and could produce severe weather. During heavy rain, GLM data can show when thunderstorms are stalled or if they are gathering strength. When combined with radar and other satellite data, GLM data will help forecasters anticipate severe weather and issue flood and flash flood warnings sooner...”
according to projections by the Population Division of the UN Department of Economic and Social Affairs. By 2030, there will be 43 megacities around the world with populations of over 10 million, up from 33 similarly sized urban centers today and just 10 in 1990...”The coming decades will see the growth of colossal megacities as the world’s population increasingly moves into urban environments, a new United Nations report predicts. Today, 55% of the world’s population is urban, a figure which is expected to grow to 68% by 2050, with the addition of 2.5 billion new city residents,
Sea Level Rise in the San Francisco Bay Area Just Got a Lot More Dire. Here’s a clip from an analysis at WIRED.com: “If you move to the San Francisco Bay Area, prepare to pay some of the most exorbitant home prices on the planet. Also, prepare for the fact that someday, your new home could be underwater—and not just financially. Sea level rise threatens to wipe out swaths of the Bay’s densely populated coastlines, and a new study out today in Science Advances paints an even more dire scenario: The coastal land is also sinking, making a rising sea that much more precarious. Considering sea level rise alone, models show that, on the low end, 20 square miles could be inundated by 2100. But factor in subsiding land and that estimate jumps to almost 50 square miles. The high end? 165 square miles lost. The problem is a geological phenomenon called subsidence. Different kinds of land sink at different rates. Take, for instance, Treasure Island, which resides between San Francisco and Oakland…”

What Happens to the Plastic We Throw Out. We’ve outsources our plastic problem to China (and the middle of the Pacific Ocean) according to an interactive post at National Geographic: “…Direct dumping contributes a significant portion of plastic litter in rivers, but land-bound trash also can make its way to water. Rainwater ushers mismanaged waste from land into local waterways, which feed into larger tributaries and rivers, which in turn empty into oceans. In this way, plastic from far inland can travel many miles to the coastline. Polluted rivers are pumping the world’s plastic into the oceans—bringing a significant portion of the estimated 9 million tons of plastic that end up in the ocean annually. That corresponds to five grocery bags stuffed with plastic trash for every foot of coastline…”
Breakthrough Solar Panel Can Harvest Power From Raindrops – Day or Night. ThinkProgress documents some amazing breakthroughs: “…For instance, China has developed “double-sided” solar panels that can generate power from light that hits their underside. That can enable a 10 percent boost in output, especially if you put the panels on a roof or other area that is painted white to help reflect the suns rays. Bloomberg New Energy Finance projects these panels could capture a remarkable 40 percent share of the market by 2025. In another remarkable advance, researchers at China’s Soochow University have demonstrated a solar cell that can generate electricity from falling rain. A recent article in the American Chemical Society’s nanotechnology journal Nano describes the innovation in an article titled “Integrating a Silicon Solar Cell with a Triboelectric Nanogenerator via a Mutual Electrode for Harvesting Energy from Sunlight and Raindrops…”
The Quest for the Next Billion Dollar Color. Bloomberg has a story worth your time: “…Technically speaking, colors are the visual sensates of light as it’s bent or scattered or reflected off the atomic makeup of an object. Modern computers can display about 16.8 million of them, far more than people can see or printers can reproduce. To transform a digital or imagined color into something tangible requires a pigment. “Yes, you have this fabulous blue,” says Laurie Pressman, vice president of the Pantone Color Institute, which assists companies with color strategies for branding or products. “But wait, can I actually create the blue in velvet, silk, cotton, rayon, or coated paper stock? “It’s not just the color,” she adds. “It’s the chemical composition of the color. And can that composition actually be realized in the material I’m going to apply it to?...”

This Physicist’s Ideas of Time Will Blow Your Mind. Here’s a clip at Quartz: “…He makes a compelling argument that chronology and continuity are just a story we tell ourselves in order to make sense of our existence. Time, Rovelli contends, is merely a perspective, rather than a universal truth. It’s a point of view that humans share as a result of our biology and evolution, our place on Earth, and the planet’s place in the universe. “From our perspective, the perspective of creatures who make up a small part of the world—we see that world flowing in time,” the physicist writes. At the quantum level, however, durations are so short that they can’t be divided and there is no such thing as time…”

A Safer Way to Watch “13 Reasons Why”? If you have a family member who plans on watching the Netflix series you may want to check out this primer from SAVE.org first: “Following the Netflix release of 13 Reasons Why in 2017, many mental health, suicide prevention, and education experts from around the world expressed a common concern about the series’ graphic content and portrayal of difficult issues facing youth. Resources and tools to address these concerns were quickly and widely disseminated in an effort to help parents, educators, clinical professionals and other adults engage in conversations with youth about the themes found in the show. In advance of the release of season 2, SAVE (Suicide Awareness Voices of Education) brought together a group of 75 leading experts in mental health, suicide prevention and education as well as healthcare professionals (see full list below) to develop tools to help encourage positive responses to the series…”
A New Theory Linking Sleep and Creativity. A story at The Atlantic is a worthy read; here’s an excerpt: “…Now, Penny Lewis from Cardiff University and two of her colleagues have collated and combined those discoveries into a new theory that explains why sleep and creativity are linked. Specifically, their idea explains how the two main phases of sleep—REM and non-REM—work together to help us find unrecognized links between what we already know, and discover out-of-the-box solutions to vexing problems. As you start to fall asleep, you enter non-REM sleep. That includes a light phase that takes up most of the night, and a period of much heavier slumber called slow-wave sleep, or SWS, when millions of neurons fire simultaneously and strongly, like a cellular Greek chorus…”

The Amish Understand a Life-Changing Truth About Technology the Rest of Us Don’t. Quartz has a fascinating story – here’s the intro: “The Amish have negotiated a pact with modernity. Whereas much of the contemporary world sees technological progress as inevitable, even a moral imperative, the Amish ideal lives in the past, circa 1850. It’s not that the Amish view technology as inherently evil. No rules prohibit them from using new inventions. But they carefully consider how each one will change their culture before embracing it. And the best clue as to what will happen comes from watching their neighbors. “The Amish use us as an experiment,” says Jameson Wetmore, an engineer turned social researcher at the Arizona State University’s School for the Future of Innovation in Society. “They watch what happens when we adopt new technology, and then they decide whether that’s something they want to adopt themselves...”

The First Holographic Smartphone Will Be Released Later This Year. Not sure I need that feature (yet), but under the heading of keeping an open mind, here’s a snippet from CNN.com: “Sure, you have a fancy iPhone X or Pixel 2 that can take amazing photographs and handle even the most graphics-heavy games. But does it have holograms? AT&T and Verizon announced this week they will start selling a holographic smartphone later this year. The Red Hydrogen One smartphone is the first phone from video equipment company Red. The Android phone’s killer feature is a “holographic display” that projects 3D images that can be viewed without special glasses. You will be able to view the images from the sides and behind, and interact with them using special hand gestures. It will also include cameras for capturing the custom 3D images...”

May 22, 2011: A strong EF-1 tornado with wind speeds up to 110 mph strikes north Minneapolis, causing extensive tree and structural damage. The tornado touched down in St. Louis Park and moved through north Minneapolis, lasting 14.25 miles before dissipating in Blaine after causing minor damage to the Anoka County Airport. The tornado reached a peak width of 1/2 mile.
May 22, 2001: Record cold high temperatures are set in over 30 cities in Minnesota, including a chilly 47 in the Twin Cities and 39 at Grand Rapids and Pine River. Half of an inch of snow falls at International Falls.
May 22, 1925: Temperatures take a nosedive from 100 to 32 degrees in 36 hours at New Ulm and Tracy.
Tornado Tally in the Twin Cities. Yes, tornadoes can and do hit the Twin Cities metro area. Here’s a good summary of recent tornado touchdowns from tripsavvy.com: “…The new scale resembles the original with tornado grades from EF0 to EF5, but it slightly re-categorizes tornadoes reflecting the latest knowledge of damage caused by different wind speeds. Situated on the northern edge of the so-called “tornado alley,” the Minneapolis-St. Paul metropolitan area experiences periodic twisters. Between 1950 and 2016, Minnesota saw 1,835 tornadoes; more than 30 touched down in Hennepin County, home to the Twin Cities…”

Here’s How Big a Rock You’d have to Drop in the Ocean to See the Rise in Sea Level Happening Now. The Washington Post explains: “…Certainly 3.3 millimeters doesn’t sound like a lot of water to displace, and it does seem, to Brooks’s point, that it’s an amount — about 0.1 inch — that would be easy to displace with a cliff collapse near San Diego. The equivalent rise relative to surface area in an Olympic-sized swimming pool would be 0.0000000000114 millimeters. That’s not possible, though, since a water molecule isn’t that small. But when you apply 3.3 millimeters of rise to the entire ocean? We’re talking about a lot of water that’s displaced — 3.3 millimeters across about 362 million square kilometers of surface area. The total volume displaced, then, would be 1.19 trillion cubic meters of water…So to make the oceans rise 3.3 millimeters, we would need to displace that 1.2 trillion cubic meters of water upward by dropping in 1.2 trillion cubic meters of dirt or stone or whatever…”

Shell Faces Shareholder Challenge Over Climate Change Approach. Here’s an excerpt from The Guardian: “Royal Dutch Shell faces a shareholder challenge over climate change this week, as investors insist oil and gas firms should offer more transparency and action on carbon emissions. A growing number of pension funds have backed a resolution at Shell’s AGM on Tuesday that calls on the company to set tougher carbon targets that are in line with the goals of the Paris climate deal. The proposal has been backed by the Church of England, the Dutch pension fund Aegon and, most recently, Nest, the workplace pension scheme set up by the UK government, which has £7m invested in Shell…”

Ancient Rome’s Collapse is Written Into Arctic Ice. I had no idea, but a good summary at The Atlantic opened my eyes: “…On Monday, scientists announced the discovery of an entirely new resource that has the potential to remake some of those centuries-old arguments over Roman politics and history. A team of archaeologists, historians, and climate scientists have constructed a history of Rome’s lead pollution, which allows them to approximate Mediterranean economic activity from 1,100 B.C. to 800 A.d. They found it hiding thousands of miles from the Roman Forum: deep in the Greenland Ice Sheet, the enormous, miles-thick plate of ice that entombs the North Atlantic island. In short, they have reconstructed year-by-year economic data documenting the rise and fall of the Roman Republic and Empire. The first news of the record was published Monday afternoon in Proceedings of the National Academy of Sciences…”

Climate Change, Crowding Imperil Iconic Route to Top of Mount Everest. Here’s an excerpt from The Washington Post: “…Several veteran climbers and well-respected Western climbing companies have moved their expeditions to the northern side of the mountain in Tibet in recent years, saying rising temperatures and inexperienced climbers have made the icefall more vulnerable. Research by the International Center for Integrated Mountain Development shows that the Khumbu glacier is retreating at an average of 65 feet per year, raising the risk of avalanche. “The icefall is obviously a dangerous place to be, especially later on in the season and with increased temperatures experienced in the Himalayas due to climate change,” Phil Crampton of the climbing company Altitude Junkies told the Everest blogger Alan Arnette earlier this year...”

Worried About Refugees? Just Wait Until We Dust-Bowlify Mexico and Central America. ThinkProgress has the article: “…But what scientists tell us we are doing to our climate will be much worse than the Dust Bowl of the 1930 — worse even than medieval U.S. droughts. Indeed, Lisa Graumlich, Dean of the University of Washington’s College of the Environment, notes that the Southwest drought from 1100–1300, “makes the Dust Bowl look like a picnic.” Remember, the Dust Bowl itself was mostly contained to the 1930s, whereas multiple studies project that future Dust Bowls will be so-called “mega-droughts” that last for many decades — “at least 30 to 35 years,” according to NASA. Further, the 1930s Dust Bowl was regionally localized. As the NASA map above makes clear, we are on track to Dust-Bowlify much of the U.S. breadbasket and Southwest, and virtually all of Mexico and Central America…”
Earth Just Experienced 400th Straight Warmer-Than-Normal Month. USA TODAY explains: “It was December 1984, and President Reagan had just been elected to his second term, Dynasty was the top show on TV and Madonna’s Like a Virgin topped the musical charts. It was also the last time the Earth had a cooler-than-average month. Last month marked the planet’s 400th consecutive month with above-average temperatures, federal scientists from the National Oceanic and Atmospheric Administration announced Thursday. The cause for the streak? Unquestionably, it’s climate change, caused by humanity’s burning of fossil fuels. “We live in and share a world that is unequivocally, appreciably and consequentially warmer than just a few decades ago, and our world continues to warm,” said NOAA climate scientist Deke Arndt. “Speeding by a ‘400’ sign only underscores that, but it does not prove anything new...”

That NASA Climate Science Program Trump Axed? House Lawmakers Just Voted to Restore It. Details via Science AAAS: “A U.S. House of Representatives spending panel voted today to restore a small NASA climate research program that President Donald Trump’s administration had quietly axed. (Click here to read our earlier coverage.) The House appropriations panel that oversees NASA unanimously approved an amendment to a 2019 spending bill that orders the space agency to set aside $10 million within its earth science budget for a “climate monitoring system” that studies “biogeochemical processes to better understand the major factors driving short and long term climate change.” That sounds almost identical to the work that NASA’s Carbon Monitoring System (CMS) was doing before the Trump administration targeted the program, which was getting about $10 million annually, for elimination this year...”

Can the San Francisco Bay be Saved From the Sea? Here’s an excerpt from The Atlantic: “…It’s totally freaky to see that with just two feet you have lost two airports. Pretty soon all of the approaches to all of the bridges are gone, most of Highway 101 and Route 37, and healthy chunks of the 80,” Schwartzenberg says. The few current pockets of affordability—Alviso, Redwood City, Fremont, Richmond, and East Palo Alto—are all underwater, as are portions of Oakland, Marin County, and downtown San Francisco. What we think of as the coastline is a blur. Looking over the map, I wonder whether the Fisher Bay Observatory is designed to get visitors not just to think about sea-level rise but to begin to imagine the unthinkable: the unsettling of the American shore...”
