Definition of an optimist? Minnesotan with a pool or a convertible. Summers at this latitude remind me of my high school girlfriend. Short and cruel. 12 summer weekends to get it right, and people take it personally when the weather doesn’t work out as advertised – or live up to their lofty expectations.

And with a June like this who needs October? We got off to a warm start, but Canada has retaliated with a silent invasion, and the natives are restless. Today looks like a step in the right direction: blue sky and 70 degrees. Tuesday should be summer-ish but heavy showers and T-storms return Wednesday.

Models bring another clipper-like disturbance into Minnesota late week, sparking random lines of T-storms Friday and Saturday, but probably no all-day washouts. ECMWF guidance now hints at a nicer Sunday, with more marauding bands of storms Monday as a hot front approaches.

I see a significant pattern shift ahead. The European model hints at 90F on the 4th, with a string of 90s the second week of July, as a heat-pump high stalls over the Plains.

I’d bet my best Tater-Tot Hotdish we’ll soon look back fondly on these cool days. Careful what you wish for.


6 PM Sunday Visible Image. Visible imagery from NOAA’s GOES weather satellite shows a mostly sunny sky across the USA with a few notable exceptions: severe storms across New Mexico and a sloppy front sparking thundery weather over the southeastern USA. A clipper dragging unusually chilly air south of the border sparked some heavy rains across Wisconsin. Image: Aeris AMP.


6 PM Sunday Enhanced Infrared Image. IR satellite images can be analyzed 24 hours a day (even when the sun goes down, unlike visible imagery) and what we’re seeing is not visible light being reflected, but the derived temperatures of clouds. The tops of T-storms poking some 45,000 feet into the atmosphere show up as orange smudges on the enhanced satellite. Image: Aeris AMP.



The Good ‘Ol Days. Yes, I know. It’s too cool for the lake. I feel your pain – there were whitecaps on my lake too on Saturday; only the brave and foolish were in the water. This cool spell isn’t sustainable. The sun is too high in the sky – there’s too much overheated air over the southern USA just waiting to surge north. At some point it will warm up. Probably overnight. Like turning on a light switch. Might I recommend that you embrace the comfortable readings, because within 1-2 weeks young and old alike will be muttering about the heat and humidity. Wait for it.

* Perceptive blog readers (and most of you are) will notice that this photo wasn’t taken in Minnesota or Wisconsin yesterday. I snapped this in Clearwater Beach, Florida Sunday. The high was a sauna-like 93F and the water temperature was 88F. Bath water. You step outside your car or hotel and you instantly begin to sweat. This kind of heat may be coming to Minnesota by the second week of July.


Atmospheric Breather. Much of America gets a slight (brief) break from the worst of the summer heat and raging thunderstorms. No widespread severe outbreaks are likely today; just generic, garden-variety thunderstorms from Kansas City to San Antonio, more instability (PM) showers over New England and a few orographic storms over the mountainous areas of the weather USA. 84-hour 12 km NAM: NOAA and Tropicaltidbits.com.


7-Day Rainfall Potential. NOAA model ensembles show some 4-7″ rainfall amounts from near Omaha and Des Moines to Chicago over the next week, as a series of storms ripple eastward along the boundary separating cool air to the north from blast-furnace heat to t he south. Northern New England and Florida may pick up some 2-4″+ amounts.


Another Slow-Motion Warming Trend. Within a week or two we may be looking back fondly at this spell of cool, comfortable weather. 70s return this week; maybe 90F in time for the 4th of July. Holiday weekend temperatures range mostly in the 70s, a few degrees cooler than average, but not as chilly as last weekend. Twin Cities ECMWF numbers: WeatherBell.


Long Range Outlook Calls for Significant Heat. GFS guidance has been hinting at this for a few days now; every subsequent model run builds the ridge over the central USA a little stronger as cool air (finally) lifts into Canada. We may be looking at an extended streak of 90s for much of the USA within 1-2 weeks, even a few 100s for the Plains. The only cool exception to the rule: Pacific Northwest and New England.



Summary of the Great Southwest U.S. Heat Wave of 2017. I’m feeling better about our cold fronts. Dr. Jeff Masters provides perspective at Weather Underground: “The great Southwest U.S. heat wave of 2017 is gradually diminishing, but it has left behind hundreds of smashed heat records, including at least four all-time hottest temperature marks for major stations. According to wunderground weather historian Christopher C. Burt, this week’s event has been the most intense heat wave yet recorded to affect the Southwest so early in the summer, coming about a week earlier than the previous great June heat waves that have affected the Southwest, like those of 2013, 1990 and 1994.

All-time hottest temperatures tied or broken during the heat wave:

Las Vegas, NV: 117° on June 20, tied the all-time record for the airport, which has a Period of Record (POR) back to 1937. However, there was a 118° reading measured by the official USWB COOP site on July 26, 1931.

Needles, CA: 125° on June 20, tied the all-time record. 126° was attained for a minute or two at one point, but not the 5-minute period needed to be deemed official. Previously, 125° was measured on June 20, 2016, and on July 17, 2005. POR: back to 1940…”


Rare Tornado Strikes New Jersey. Philly.com has details, and a link to video: “Toto, I have a feeling we’re not in South Jersey anymore. The National Weather Service confirmed two tornadoes did touch down down near Howell in Monmouth County, New Jersey on Saturday morning, part of swift-moving thunderstorms that slammed the region. The first tornado ripped through the parking lot of a Home Depot on Route 9 around 7:20 a.m., with wind speeds reaching 75 mph. It was caught on video and widely shared on social media…”

Sunday Severe Storm Reports. There were numerous reports of heavy rain yesterday over Wisconsin, a few severe thunderstorm wind damage reports over New England, large hail fell in New Mexico. For details click here, courtesy of NOAA and AerisWeather.


Flood-Prone Town Protects Itself Against Waters While Letting a River Roam. The town in question is near Sacramento, according to a story at Emergency Management: “Sometimes better flood protection comes from giving a river some space to roam. Hamilton City, 85 miles north of Sacramento, learned that lesson from a new levee project that both protects against flooding and restores wildlife habitat. The levee will be set back from the Sacramento River for most of its 7 miles, allowing the river to spill over its banks and creating 1,400 acres of riparian forest and grassland. A model for flood-threatened areas nationwide, this project was the first designed by the U.S. Army Corps of Engineers to benefit both people and the environment…” (File photo: Shutterstock).


Average Dates of Hottest Summer Weather. A fascinating map, courtesy of climate guru Brian Brettschneider shows the warmest weather off the year usually occurs before the 4th of July from southern Arizona and New Mexico into southwest Minnesota. East Texas? Hottest weather usually comes after August 8.


Hottest Temperatures. Historical records show the hottest temperatures of the year exceed 100F from the Carolinas and Plains to eastern Washington State. Temperatures in northern New England peak in the upper 80s.



Prince Was a Secret Patron of Solar Power. Bloomberg explains how Prince focused his money and passion on renewable energy: “Before his abrupt death a year ago, the pop musician Prince made an investment in green energy that’s now helping solar start-ups weather an assault from President Donald Trump. It started with a conversation in 2011 between Prince and his friend Van Jones, a CNN commentator and California human rights agitator and onetime green-jobs adviser to President Barack Obama. “He asked, ‘If I have a quarter-million dollars, what can I do with it?’” Jones recalled in an interview. “My wife said he should put solar panels all over Oakland.” That led to the creation of Powerhouse, a rare for-profit incubator dedicated to putting clean-tech entrepreneurs together with investors…”




Why Offshore Wind Farms Can’t Handle the Toughest Hurricanes. A risk, and an opportunity. Here’s an excerpt from PBS NewsHour: “Offshore wind developments are rapidly expanding. But most wind turbines are not built to withstand a direct hit from the strongest hurricanes, according to a new study in Geophysical Research Letters that models the worst-scenarios caused by category-5 storms. Researchers predict new offshore turbines would face hurricane wind gusts of more than 223 miles per hour — but the turbines can only manage gusts of 156 miles per hour based on current engineering standards. Part of the problem: Offshore turbine designs often draw from onshore wind turbines in Europe, where hurricane conditions are essentially nonexistent…”

Why the World Needs to Get Smarter About Water Consumption. The author of a story at Eco-Business explains that in a world where 6 billion people will live in cities by 2045 we need to get a lot smarter about how we manage our most precious natural resource: “In 1900, just 15 per cent of the world’s population lived in cities. Now that proportion is over 50 per cent, which is a lot of people. In fact, it means around 4 billion human beings rely on urban infrastructure to keep them warm, mobile and clean. Technology helps with this of course. Digital sensors, smart phones and smart home appliances allow for a new kind of understanding between citizens and city officials. In this so-called “smart city”, information and communication technologies (ICT) and the internet of things (IoT) are used to enhance city living. Smart cities are a major part of achieving the goal set by the United Nations of making urban environments “inclusive, safe, resilient and sustainable”...

Power Causes Brain Damage. You don’t say? The Atlantic explains: “…The historian Henry Adams was being metaphorical, not medical, when he described power as “a sort of tumor that ends by killing the victim’s sympathies.” But that’s not far from where Dacher Keltner, a psychology professor at UC Berkeley, ended up after years of lab and field experiments. Subjects under the influence of power, he found in studies spanning two decades, acted as if they had suffered a traumatic brain injury—becoming more impulsive, less risk-aware, and, crucially, less adept at seeing things from other people’s point of view. Sukhvinder Obhi, a neuroscientist at McMaster University, in Ontario, recently described something similar. Unlike Keltner, who studies behaviors, Obhi studies brains. And when he put the heads of the powerful and the not-so-powerful under a transcranial-magnetic-stimulation machine, he found that power, in fact, impairs a specific neural process, “mirroring,” that may be a cornerstone of empathy...”

The Botanists’ Last Stand. It’s hard watching species go extinct for a living, according to a story at Quartz: “…I’ve already witnessed about 20 species go extinct in the wild,” Perlman says. “It can be like you’re dealing with your friends or your family, and then they die.” Perlman tells me this as we drive up a winding road on the northwestern edge of Kauai, the geologically oldest Hawaiian island. Perlman is 69 with a sturdy build and white hair. That’s been enough to last him 45 years and counting on the knife’s edge of extreme botany. The stakes are always high: As the top botanist at Hawaii’s Plant Extinction Prevention Program (PEPP), Perlman deals exclusively in plants with 50 or fewer individuals left—in many cases, much fewer, maybe two or three. Of the 238 species currently on that list, 82 are on Kauai; Perlman literally hangs off cliffs and jumps from helicopters to reach them…”

The Death of Expertise. With the Internet now everyone is an expert – on everything – right? I read it on the Internet – it must be true. Dan Satterfield reviews a book at AGU Blogosphere: “Tom Nichols, a professor of national security affairs at the US Naval War College, says America has become a country “obsessed with the worship of its own ignorance.” Americans have always been skeptical of intellectuals and experts. Today, says Nichols, that attitude has mutated into outright hostility. In general, Americans have never been so willing to reject the knowledge of those who actually know something. This embrace of self-righteous ignorance bodes ill for the nation’s future. Nichol’s puts some blame on US universities, which fail to instill critical-thinking skills in students, and on the proliferation of news sources that compete by affirming their audiences’ biases...”


A Rare Journey Into the Cheyenne Mountain Complex, a Super-Bunker That Can Survive Anything. WIRED.com has an eye-opening story: “…Shielded by 2,500 feet of granite, these people gather and analyze data from a global surveillance system, in an attempt to (among other, undisclosed things) warn the government’s highest officials of launches and missile threats to North America.Their military mole-city, completed in the mid-1960s amid Cold War worries, is—when fully buttoned-up—highly resistant to nuclear bombs, electromagnetic bombs, electromagnetically destructive behavior from the sun, and biological weapons. It’s designed to do its job, and let those inside do theirs, in the worst of worst-case scenarios. And with escalating fears about North Korean aggression and nuclear capabilities, Cheyenne Mountain’s ability to predict and survive a nuclear attack resonates more than it did just a few months ago…”

Slow Time is God’s Time. We can learn a lot from the Amish. Vestoj has a thoughtful story: “‘PATIENCE’ IS THE GIGANTIC message scrawled on every Amish buggy plodding on modern highways. ‘The horse is our pacer,’ as one Amish man puts it, ‘We can’t speed up like you can in a car.’ The slow-paced hymns in Amish church services linger for twenty minutes. The most traditional Amish do not set their clocks ahead an hour in the summer season as other Americans do. These traditionalists favour slow time, God’s time, established by the rising and setting of the sun. In the midst of a hyper-speed culture that wants more and more, faster and faster, from instant downloads, immediate tweets, express mail, and extreme sports to rushed everything, the Amish stubbornly resist the velocity of hypermodernity...”

All Aboard Air Koryo, North Korea’s Fleet of Ancient Soviet Planes. WIRED.com has a fascinating piece: “North Korea possesses the technological wherewithal to develop a nuclear bomb, launch devastating cyberattacks, and even hurl rockets toward its enemies. Yet it can’t manage to put together an airline that isn’t heavily stocked with Cold War-era Russian airliners. That said, the Air Koryo fleet is pretty cool in a retro kind of way, and a passionate band of aviation buffs happily spend their days taking joyrides. “They’re beautiful,” says Arthur Mebius. “These planes still have the original interiors they were delivered with…”

Climate Stories….

Christians Dedicated to Saving the Planet. I don’t worship Creation, but I do serve God when I protect what he created. Clean air, clean water and a stable climate should be non-negotiable, something all of us can agree on. Here’s an excerpt of an Op-Ed at Lancaster Online: “As Christians — one a lifelong Republican and president of the Evangelical Environmental Network — we’re part of a growing number of faith-based, bipartisan and conservative groups dedicated to caring for our children’s health by being good stewards of the earth. Since 1892, scientists have told us that burning fossil fuels adds CO2 to the air, resulting in a warming earth. More than 50 years ago, scientists warned then-President Lyndon Johnson of climate impacts and the “fever” we’re giving the earth, and today every major scientific body in the world acknowledges the reality of human-induced climate disruption…”




“Call Me Crazy, but Conservatives Should Probably Conserve”. Clean air, clean water and a stable climate shouldn’t be a partisan issue. My thanks to everyone who stopped by Salem Lutheran Church in Deerwood, Minnesota Friday afternoon. Here’s an excerpt from The Brainerd Dispatch: “…His realization that climate change was happening came not from Al Gore, but simply observing the new extremes of weather, Douglas said. It made sense to him both from the capitalist and Christian perspectives to work to combat climate change. Teddy Roosevelt launched the National Park Service, and Richard Nixon, the Environmental Protection Agency. Ronald Reagan once said the government had a duty to protect against the environmental damages of industrial development, Douglas pointed out. Douglas said it was inherent that Republican ideals align with environmental protection. “Call me crazy, but I think conservatives should probably conserve,” he said. “Otherwise, change your name…”

From Heatwaves to Hurricanes, Floods to Famine: Seven Climate Change Hotspots. The Guardian takes a look at where the symptoms of a rapidly changing climate may have the most immediate implications: “…The evidence for the onset of climate change is compelling. But who and where is it hitting the hardest? How fast will it come to Africa, or the US? What will be its impact on tropical cities, forests or farming? On the poor, or the old? When it comes to details, much is uncertain. Mapping the world’s climate hotspots and identifying where the impacts will be the greatest is increasingly important for governments, advocacy groups and others who need to prioritise resources, set goals and adapt to a warming world. But lack of data and different priorities make it hard. Should scientists pinpoint the places most likely to see faster than average warming or wetter winters, or should they combine expected physical changes with countries’ vulnerability? Some hot-spot models use population data. Others seek to portray the impacts of a warming world on water resources or megacities…”
