June 8, 1972: 8 inches of rain falls in 7 hours at Madelia Township in Wantonwan County.
June 8, 1893: Violent winds occur at Maple Plain from 1:30 to 2:15pm. A large frame house was moved 8 feet from its foundation. Many barns and haysheds blown over by the wind. One barn was blown across Dutch Lake.
Cool & Comfortable Gives Way to Hot and Sweaty
With artificial intelligence will computers ever be able to tell stories, with no human intervention? Will “Siri” whisper you own personalized forecast?
An article in today’s weather blog asks a rhetorical question: with smart phone apps and computer models do we need weather forecasters? Interesting question, and believe me, I’m hedging my bets. At the risk of sounding defensive, we’re still a long way from computers providing perspective and context. That’s true in news and sports, as well.
But the future is unknowable; all meteorologists would be well advised to have a Plan B, just like everyone else.
Today will be a tonic for the soul: sunny, upper 70s with comfortable dew points. Soak it up. The approach of a sauna-like airmass sparks a few T-storms tonight into early Thursday. On the hot side of the front south winds lure a drippy dew point into the mid-70s. With temperatures in the mid-90s the heat index Friday could top 100F.
Models suggest slight relief Saturday as surface winds turn to the east; T-storms Monday, followed by a reprieve from the heat on Tuesday.
Dangerous Heat Index Friday? As the old saying goes, it’s not the heat, it’s the humidity. Factoring dew points well into the 70s an air temperature of 92 or 93F may feel like 100 degrees by late afternoon Friday, based on NOAA guidance. The definition of lake-worthy. Source: Aeris Enterprise.
European Numbers. ECMWF guidance shows low 90s Friday, which may wind up being a couple degrees too cool. We’ll see, but there’s now little doubt we won’t be simmering, baking in the 90s Friday afternoon. A wind shift to the northeast behind a feeble cool front provides slight relief Saturday (upper 80s to near 90) with more cooling Sunday. Graphic: WeatherBell.
Nocturnal Thunderstorms. Much of our rain in June comes at night, as low-level winds interact with warm frontal boundaries, allowing convection to initiate after dark. NOAA’s 4 KM NAM model hints at a few T-storms tonight into early Thursday, forming along the leading edge of our upcoming sauna. Source: AerisWeather.
Significant Rain Early Next Week? NOAA’s models have been fairly consistent, predicting heavy showers and T-storms Monday as (slightly) cooler air arrives from the Dakotas. Not sure we’ll pick up 3″ of rain, but some 1″+ amounts seem plausible. Source: Aeris Enterprise.
Next 2 Weeks: Mostly 80s. Looking out 2 weeks I suspect 80s will be the rule, with a few days in the 90s. By the 4th week of June the approach of cooler, Canadian air may set up a pattern ripe for more frequent thunderstorms.
With iPhone and Computer Models, Do We Still Need Weather Forecasters? I’m a bit biased, of course, but I would hope that there’s always a place for context, perspective and analysis, adding value above and beyond what a computer can do, but who knows? Choosing which model to believe is another ongoing challenge. Here’s an excerpt from Ars Technica: “…But most everybody has looked on their phone or some other device already. So what am I going to do? Am I just going to rehash everything they already know?” Many forecasters have been asking themselves this question lately. Two technologies have converged to rapidly displace the primary function of meteorologists. First are computers that are generally better forecasters than humans. For most types of weather, numerical weather prediction has superseded human forecast methods. And secondly, thanks to the Internet and increasingly ubiquitous weather apps on mobile devices, people have continuous, immediate access to 5-day, 7-day or 10-day forecasts. As technology drives automation and machines take job after job once performed by humans, are meteorologists next in line?...”

Tropical Storm Colin Produced 11 Inch Rains and a 4-Foot Storm Surge. The Washington Post’s Capital Weather Gang has a post-mortem on Colin: “Despite its lack of organization, it has produced impressive rainfall over the Southeast. Parts of central and northern Florida, including the Tampa Bay area, received 8-11 inches. Gainesville, Fla., which received 5.65 inches, had its 2nd wettest June day and 8th wettest day (of any month) on record, according to the Southeast Regional Climate Center. The map below shows the estimated rainfall totals from Sunday to Tuesday morning…”
Attacking Storm Chasers Doesn’t Accomplish Anything, And It’s Often Misinformed. Here’s an excerpt of a retort to a recent Eric Holthaus column from Ian Livington at Capital Weather Gang: “...Chasers, ranks filled with tons of meteorologists, are generally smart folks and excellent risk assessors. Observers should keep this in mind while continuing to judge us on safety practices and choices when it comes to proximity to tornadoes. The well-known chasers who were killed in 2013, led by tornado researcher Tim Samaras, were giants of the field. But they chased in a particularly dangerous way while trying to put probes in front of tornadoes. Most chasers don’t chase that way. And very few are out there with, as Holthaus calls it, “dollar signs in their eyes, as bystanders’ livelihoods are destroyed…”
The Storm and the Fury: 80 Vintage Photos of Hurricane Seasons Past. NOLA.com in New Orleans has a terrific photo essay; here’s an excerpt: “Bring up the subject of hurricanes to most residents of South Louisiana, and killer storms like Betsy in 1965, Camille in 1969 and She-Who-Shall-Not-Be-Named in 2005 crop up consistently. But time and again over the decades, the fortitude of locals has been tested by storms that — while maybe not as well remembered as those name-brand milestones — were still just as life-altering for many local residents. Time and again, locals have proven equal to the task; Louisianians are not prone to bowing down in difficult times…”

An Above Average Season for Hurricanes in the Atlantic? NOAA is predicting an average summer and fall for tropical development, but Penn State’s ESSC forecast calls for an above-average year for tropical cyclones in the Caribbean and Atlantic basin. 3 named storms by June 6? That’s the most on record so early in the season, but is there a correlation with an above-average hurricane season? Here’s an excerpt: “ESSC scientist Michael E. Mann, alumnus Michael Kozar, and researcher Sonya K. Miller have released their seasonal prediction for the 2016 North Atlantic hurricane season, which officially starts on June 1st and runs through November 30th. The prediction is for 18.9 +/- 4.4 total named tropical cyclones, which corresponds to a range between 14 and 24 storms with a best estimate of 19 named storms. This prediction was made using the statistical model of Kozar et al. (2012, see PDF here). This statistical model builds upon the past work of Sabbatelli and Mann (2007, see PDF here) by considering a larger number of climate predictors and including corrections for the historical undercount of events (see footnotes)...”
India’s Crippling Heat Wave Continues With Temperatures Over 116F. TIME has the details; here’s an excerpt: “More than 130 people have now died from the heat wave and resultant drought. Despite the onset of the monsoon in several parts of the country, India continues to reel under a brutal heat wave that has now lasted more than two months and claimed dozens of lives. On Monday, temperatures rose to more than 47°C (116.6°F) in the western state of Rajasthan — which also recorded India’s hottest day ever at 123.8°F last month — the Press Trust of India reported…” (Map credit: WeatherBell).
Editorial: Cities, Counties Must Deal With “New Normal” of Rain, Floods. Here’s an excerpt of an Op-Ed at the Beaumont Enterprise in Texas: “…Places in Houston have had two “500-year floods” this spring. The city of Brenham has already set a record for its wettest calendar year on record. This week it got more than 19 inches of rain in 48 hours. That’s more than Los Angeles is supposed to get in an entire year. Half of our entire state is under flash flood watch or warning. Keep in mind that all of this has no connection with the “official” hurricane season, which began this week. Our rainfall isn’t cascading in from the Gulf of Mexico. It’s coming inland along the same patterns our parents and grandparents dealt with – only more often, and heavier. After a while, conditions like this aren’t abnormal. They become the new normal, and we have to start adjusting to them...” (File photo: U.S. Coast Guard).
Massive Rehearsal Planned for Northwest Megaquake, Tsunami. WCBD News 2 has the story – here’s an excerpt: “Imagine a devastating earthquake and tsunami have cut off Pacific Northwest coastal communities. Phone and internet service have collapsed. Ham radio operators living on the stricken coast fire up their radios, contact emergency managers and report on the magnitude of the disaster so that no time is wasted in saving lives. This is the kind of scenario that will be rehearsed during the second week of June in a massive earthquake and tsunami readiness drill that has been developed by the U.S. government, the military, and state and local emergency managers over the past few years to test their readiness for what — when it strikes — will likely be the nation’s worst natural calamity…”

Cascadia, a State of Mind and a Megaquake. A story at The Los Angeles Times caught my eye (with a son and daughter in law living in Seattle); here’s an excerpt: “…Yet now, as the region booms with newcomers drawn to its technology economy, Cascadia’s distinctiveness has become both indisputably clear and darkly complicated. Its very existence is threatened with what scientists say is a strong likelihood that, sooner or later, it will be faced with the largest earthquake ever recorded in the United States. On Tuesday, as many as 20,000 people across Washington, Oregon, California and Idaho, mainly federal employees, will begin a four-day exercise called “Cascadia Rising” — a trial run at responding to a massive magnitude 9.0 quake on the Cascadia Subduction Zone off the northwest coast near here, and the tsunami that would inevitably accompany it…”

An Attack on the Grid? Power Execs Push Back on Koppel Claims. USA TODAY has the article; here’s an excerpt: “Eight months after veteran broadcast journalist Ted Koppel published a book predicting a devastating cyberattack on the U.S. power grid, leaders of the utility industry are sounding off over what they say is an exaggerated claim. “We’re speaking out on it now because we think there is an important story to tell,” Scott Aaronson, the managing director for cyber and infrastructure security at the Edison Electric Institute, said last week at a briefing for reporters...”
Steven Chu Criticizes Clean Power Plan for Neglecting Nuclear. Forbes has the article; here’s the intro: “Former Energy Secretary Steven Chu doesn’t think energy storage can solve the reliability problems of wind and solar quickly enough, he said Friday, which led him to criticize the Environmental Protection Agency for neglecting nuclear power in its Clean Power Plan. “Even though the Clean Power Plan says we need nuclear and maintains the same ratio, they give no credit for it,” Chu said during a debate at the Silicon Valley Energy Summit hosted by Stanford University. “We should make a Clean Power Plan that’s based on clean energy, not renewable energy...” (File image: Shutterstock).
The Rapid Growth of Electric Cars Worldwide, in Four Charts. Vox has the story – here’s a clip: “…The United States now has 400,000 electric vehicles on the road — a massive increase since 2010, though well short of Obama’s goal of 1 million by 2015. Meanwhile, China has become the world’s largest market, overtaking the US in annual sales last year. Is 1 million a lot? It depends how you look at it. It’s jaw-dropping growth given that there were only a few hundred electric vehicles on the entire planet back in 2005. And the total number of electric vehicles worldwide has tripled just since 2013…”

Go Inside an Industrial Plant That Sucks Carbon Dioxide Straight Out of the Air. MIT Technology Review has the story; here’s the intro: “Carbon dioxide emissions must decrease to nearly zero by 2040 if global warming by the end of this century is to be held to 2 C. But we may well miss that target. A pilot plant started last fall at Squamish, British Columbia, is testing a backup plan: sucking carbon dioxide directly out of the air. Capturing ambient carbon dioxide is a tall order because, for all the trouble it causes, the greenhouse gas makes up just .04 ercent of the air we breathe...”

Tropical Storm Colin 2016. Here’s an excerpt from Climate Signals: “Tropical Storm Colin formed five days into the Atlantic hurricane season, just as Tropical Storm Bonnie, which had arrived five days ahead of the season’s official start, dissipated. Colin marks the earliest arrival of the third tropical storm in the Atlantic hurricane season, thanks to unusually warm waters that have helped to fuel the early season storms. Global warming has been found to increase the rainfall associated with hurricanes. In addition seal level rise is elevating the storm surge driven by hurricanes. There is also a significant risk that ocean warming may be directly increasing hurricane intensity...” (Visible loop: WeatherTap).
That 70s Myth – Did Climate Science Really Call for a “Coming Ice Age?” Ars Technica has the story; here’s the intro: “One of the undying, zombie-like arguments against climate change is that you can’t trust climate scientists because they started out making doom and gloom claims about global cooling in the 1970s. But this, along with many other things comedian Dennis Miller has said on late night talk shows, needn’t be taken seriously. By the time fears of an ice age reached the public’s attention, there was a long history of concerns about warming. The idea that burning fossil fuels would warm the planet can be traced back to an 1896 paper by Swedish scientist Svante Arrhenius. In the 1930s, Britain’s Guy Callendar concluded that global warming was already underway. So it seems a bit odd that anyone worried about cooling. What was really going on back in the ’70s—both in science and in the media?…”

The Great Barrier Reef: a Catastrophe Laid Bare. The Guardian has the story; here’s the intro: “Australia’s natural wonder is in mortal danger. Bleaching caused by climate change has killed almost a quarter of its coral this year and many scientists believe it could be too late for the rest. Using exclusive photographs and new data, a Guardian special report investigates how the reef has been devastated – and what can be done to save it…”
A Bridge to Nowhere. Is natural gas delaying the arrival of clean energy? Here’s an excerpt from ScienceLine: “We’re wrapping an extra blanket around our planet that it doesn’t need,” climate scientist Katharine Hayhoe said on Twitter. Hayhoe’s remark refers to the devastating effects of global warming and paints this crisis in terms even children can understand, which is helpful because global climate change will shape their lives. The earth is on a steady road to a hotter future, and most people agree that changing the way people generate and use energy could help ease the burden of future impacts on our children…”

Historic Deluge Hits Texas. Houston, You Have a Problem. Here’s an excerpt of an Eric Holthaus post at Slate: “…It’s impossible to know exactly how much climate change factors into the likelihood of these specific events, but it’s certain that it has. Hotter hots, drier droughts, and heavier rains have long been predicted as a consequence of rising greenhouse gas levels that speed up our planet’s water cycle and intensify many already extreme weather events. (The lingering effects of a record-setting El Niño is also likely playing a part in the recent Texas floods. And, it’s not just Texas: Over the past several days, major floods have also hit Paris and other parts of Europe, Sri Lanka, and Ethiopia.) Texas has seen some of the most drastic change in the United States, with Houston registering a 167 percent increase in the biggest downpours since the 1950s...” (2015 file photo: weather.com).
Alaska’s Huge Climate Mystery – And Its Global Consequences. Chris Mooney reports for The Washington Post; here’s the intro: “In recent years, climate scientists have grown increasingly concerned about a carbon problem in the far north. The fear is that with the higher latitudes of the planet warming extremely rapidly, that heat itself, and some of its consequences — such as raging wildfires in northern forests — could unleash a climate disaster. Perennially frozen northern soils, known as permafrost, contain enormous amounts of carbon because the slow and cold chemistry of the Arctic makes them the repository of thousands of years of frozen plant remains…”

The previous season, nearly 60% of Wisconsin honeybees died off during the winter, a rate that was 4 times higher than the one considered acceptable. In six of the past seven seasons, bee die-off rates have climbed over 30%. According to the US Department of Agriculture (USDA) data, 44% of bees died off across the nation this season. As per experts, the die off is an outcome of using insecticides, global warming and a mite. With the fall in the number of honeybees in Wisconsin, the beekeepers should import new hives from throughout the country…”
Meteorologist Don Paul: How I Learned Manmade Climate Change Is The Real Deal. Here’s an excerpt of Don’s Op-Ed at The Buffalo News: “…When climate models are run, they can be initialized with different data sets and different levels of greenhouse gas in particular. To a model, when these models are run with the carbon dioxide level of the year approximately 1900 (around 297 ppm rather than the current 403 ppm), and natural warming (not man-made) forces are maxed up, the globe would have shown slight cooling through the end of the 20th century. Left to so-called normal cyclic changes, even with other warming mechanisms in nature pumped up, no other explanation can be found for warming that has been ongoing at different rates over recent decades...”
