A/C Optional - While Much of Northern Hemisphere Sizzles in Record Heat

A/C Optional

In the early 1800s did settlers at Fort Snelling complain about the heat & humidity? Probably. Maybe they took frequent dips in the lake or river to cool off. Somehow they made it work. Today most of us take air conditioning for granted.

There are exceptions.

My oldest son just moved into a new apartment in Seattle. He couldn't get the A/C to turn on so he went to the front office, where they apparently stared at him like he had horns and a tail. "We don't have A/C in this building. In Seattle A/C is optional." Uh huh.

In the last week nearly 500 heat records have been set out west. London broiled near 100F yesterday. Record heat has killed thousands of people in India and Pakistan in recent weeks.

Then why does it feel more like early May than early July out there? The same stalled ridge of super-heated air over the west is setting the stage for west/northwest winds high above Minnesota, meaning frequent burps of cool air from that great air conditioner to the north, Canada. I think July will be much cooler than average.

The 4th of July looks sunny, dry and lake-worthy with highs in the 80s; in fact T-storms may hold off until Sunday night. 90s may be quite rare this summer in Minnesota.


Clouds, Smoke and Cool Sunshine. Look carefully at the Wednesday afternoon visible satellite loop and you can see a plume of milky white (smoke) stretching from near Fargo to Willmar and Shakopee, the core of the plume extending all the way to Alaska. Morning clouds and light showers gave way to some comfortable sunshine later in the day. Considering we could easily be sizzling in the 90s no complaints. Loop: NOAA and AerisWeather.


Mostly-Dry Into The 4th of July. Consider it a minor meteorological miracle - dry skies, reasonable humidity and light winds into Saturday with some sun each day as temperatures slowly mellow. Much of Sunday may be dry as well, with T-storms holding off until Sunday night. 84-hour NAM guidance: NOAA.


Slightly Cooler Than Average. No hot fronts, no chilly fronts - temperatures trend close to average in the coming days, but enough dry Canadian air is pushing south for nighttime temperatures to fall into the low and mid 60s, with a few exceptions, meaning no oppressive nighttime dew points. The best chance of T-storms: Sunday night into early Monday. Source: Weatherspark.


Hudson Bay Cut-Off Low in Mid-July? Predicted 500 mb winds (GFS) in mid-July show a head-scratchingly cool bubble of low pressure pinwheeling near Hudson Bay in 2 weeks, flinging a series of cooler, drier fronts south of the border, preventing Minnesota and the Great Lakes from overheating anytime soon. Heat lingers from the west coast into the deep south and Mid Atlantic states.


Unprecedented June Heat On Four Continents; Wimbledon Roasts in Record Heat. 98.1F in London yesterday? Jeff Masters at Weather Underground takes a look at scorching heat, now proving deadly - here's an excerpt: "...We've already seen two of the planet's top ten deadliest heat waves in history over the past two months; the Pakistani government announced on Wednesday that the death toll from the brutal June heat wave in Pakistan's largest city, Karachi, had hit 1,250. According to statistics from EM-DAT, the International Disaster Database, this makes the 2015 heat wave in Pakistan the 8th deadliest in world history. The heat wave that hit India in May, claiming approximately 2,500 lives, ranks as the 5th deadliest..."


Heat Dome Parked Over West Shatters Temperature Records, Sets Fires. Andrew Freedman has a good overview at Mashable; here's an excerpt: "The West is baking under a heat dome that has sent temperatures soaring to historically high levels, further drying out soils and priming the region for fast-spreading wildfires. The heat wave is noteworthy for its severity, extent and duration. During the past seven days alone, 465 warm temperature records have been set or tied across the country, mainly in the West, with 49 monthly warm temperature records set or tied, according to the National Center for Environmental Information in Asheville, North Carolina..."

Wildfires Are Raging, And It's About To Get A Whole Lot Worse. Business Insider has the story; here's the introduction: "Summer just started but wildfires are already ravaging the dried-out West coast. Since the beginning of June, nearly 300 fires have burned in Alaska, with a total of 1.1 million acres already destroyed just one month into the fire season. Right now, a fire in the Galena Zone area of Alaska has burned through 100,000 acres..." (Photo: Lucy Nicholson, Reuters).


June Has Been Wet - Just Like Normal. No, this shouldn't come as a shock, considering June is (historically) the wettest month of the year. Here's an excerpt of a good post from AerisWeather meteorologist D.J. Kayser: "The rain bucket has been quite busy across the state again this month so far, with some areas of Minnesota picking up over 5″ of rain with only a few days left of June. So far, the top rain amount reported this month (through early on the 26th) was 8.00″ 0.3 miles SW of Ellendale by a CoCoRaHS observer. A COOP observer in Melrose has reported 7.65″ – and another COOP observer 3 miles southeast of Albert Lea has picked up 7.56″ so far. Any area in red above shows observed precipitation of 5″ or more through the month so far..."


U.S. Chamber of Commerce Works Globally To Fight Antismoking Measures. I wonder what the local chapters of the Chamber of Commerce think about this? Here's an excerpt from an infuriating story at The New York Times: "...From Ukraine to Uruguay, Moldova to the Philippines, the U.S. Chamber of Commerce and its foreign affiliates have become the hammer for the tobacco industry, engaging in a worldwide effort to fight antismoking laws of all kinds, according to interviews with government ministers, lobbyists, lawmakers and public health groups in Asia, Europe, Latin America and the United States..."

I Hate iTunes. And I Think Apple Does Too. I don't look forward to synching my iDevices either - I have to agree that iTunes has become a bloated mess, not the typical, elegant, streamlined and simplified Apple Experience we've come to appreciate. Here's an excerpt of a story at Quartz: "...Don’t blame my exhaustion on my friend’s lack of technological know-how or my own dwindling patience. Blame iTunes. Once the ultimate in music file management and the centerpiece to Apple’s financial turnaround, this program has evolved from a simple, dependable music player into the biggest example of bloatware in computers today. But why mince words? I hate iTunes. And I think Apple does, too..."


You Could Buy Your Own Personal Jetpack by 2017. Bingo. Santa, I only have one thing on my list. Here's an excerpt from Quartz: "The future is nearly here. Jetpack maker Martin Aircraft has announced that its first jetpacks—aimed at first responders for use in search and rescue missions—will be ready for delivery in the second half of 2016, and that its “personal jetpacks” for the consumer market will be ready for use by the middle of 2017. The company’s P12 jetpack has a maximum speed of 74 kilometers per hour (46 miles per hour) and can rise up to 3,000 feet (900 meters)..." (Image credit: Martin Aircraft).

More Evidence That Global Warming Is Intensifying Extreme Weather. Here's an excerpt of an article at The Guardian from St. Thomas professor and climate scientist John Abraham: "...They separated changes in circulation from changes in thermodynamic effects. What they found is that most regions have seen increases in summertime warm temperatures in the past three decades. Furthermore, they found that in some regions, a large part of this trend is due to the increases in anticyclonic circulation and atmospheric blocking. The blocking that has been associated with extreme swings of weather (bringing very warm weather to the Western USA and simultaneous cold weather to the east for instance)..."


Alaska Glaciers Melting Faster As Planet Overheats. Here's an excerpt from rtcc.org: "...He and his colleagues calculated that Alaska is losing ice at the rate of 75 billion metric tons a year. Such research is just one more piece of careful cross-checking in the great mosaic of climate research: another systematic confirmation that overall, glaciers are not losing ice in response to some natural cycle of change of the kind that occasionally confuses the picture for climate science. The agency at work is largely global warming as a response to the steady rise in atmospheric carbon dioxide as a consequence of the burning of fossil fuels..."

Love Thy Planet: Pope Francis' Bully Pulpit On Climate Change. Here's an excerpt of an Op-Ed from the Editorial Board at The Pittsburgh Gazette: "...Even to the pope’s supporters, his attacks on capitalism may seem excessive. His observations on technology and social organization sometimes are reminiscent of Cold War-era doomsday prophecy. But no one should expect Pope Francis, or any other individual, to have all the answers. With this encyclical, he has brought greater attention to the danger that global warming poses to humanity and called on people to respect and sustain the planet they share."


Zero Carbon Emissions: The New Language of Climate Change. Here's an excerpt from DeSmogBlog: "...In future, people will look back and question why we burned such precious resources so wastefully. Fossil fuels are solar energy, concentrated over millennia and useful for numerous applications, many of which we probably haven’t even discovered. Yet we’ve burned them largely so people, often solo drivers, can move around in tonnes of metal and plastic on land-destroying and expensive infrastructure. And we’ve used them to create increasing amounts of plastic packaging and unnecessary products that are now choking our oceans and land. Moving toward zero carbon emissions — in a much shorter timeline than agreed upon by Canada, France, Germany, Italy, Japan, the United Kingdom and the United States — is absolutely necessary, and not just for the climate. Eliminating fossil fuel energy will cut dangerous pollution, create new economic opportunities and ensure resources are available for wiser applications..."


Neil deGrasse Tyson's Message To People Who Think Pope Francis Shouldn't Talk About Climate Change. Here's a snippet from ThinkProgress: "...On Tuesday, the author and host of the late-night talk show StarTalk tweeted that despite being a religious figure, Pope Francis is more than qualified to talk about scientific issues. In a series of tweets, Tyson noted that the Vatican Observatory employs dozens of scientists who inform the pope on issues like climate change. “Yes, it’s possible to be a supreme holy figure yet still know what you are talking about regarding the Climate,” he tweeted..."


Why Cities Will Be Vital Players at Paris Climate Talks. Here's an excerpt of a post from the Mayor of Paris, courtesy of Huffington Post: "...In cities and local regions across the globe, tackling climate change is also an opportunity for raising standards of living and improving jobs markets. Better mass transit means easier commutes. Reducing air pollution means improved public health. Developing parks and other new urban green spaces does not just offset carbon but attracts businesses, fosters employment and improves wellbeing. It is also a major social issue: energy-efficient buildings don't just cut emissions, they lower power bills too..."

China Pledges To Halt Growth of Carbon Emissions in Climate Plan. We'll see if the actions match the words, but this could be another encouraging step, taken at face value. Here's the intro to a story at The New York Times: " China, the world’s biggest greenhouse gas polluter, pledged on Tuesday to wean its economy off dependence on fossil fuels as it grows, and said it would halt the growth of its emissions as soon as it could. How quickly and how much China’s emissions will grow is crucial to the arithmetic of global climate change, and the levels of greenhouse gases in the atmosphere that are driving that change, especially carbon dioxide. China’s motor vehicles, factories, power plants and boilers released 29 percent of the world’s carbon dioxide emissions in 2013 — twice the amount released by the United States, the world’s largest economy and second-largest carbon polluter..."


Melting Arctic Sea Ice Could Be Disrupting The Oceans' Circulation - With Major Consequences. It turns out we're conducting an experiment on the atmosphere, and the oceans. Here's an excerpt from The Washington Post: "...A weakened Atlantic overturning circulation has the potential to cause some unexpected consequences. If the current slows down and less warm water gets transported north, then less heat will be transferred in regions such as Western Europe. According to Moore, Europe could actually experience a cooling effect in the future as a result of this — although how pronounced this cooling will be remains unclear. Climate change is expected to continue raising temperatures across the globe, so overturning-related cooling effects in Europe will likely be offset by global warming. It may be that Europe will continue to heat up, but at a slower pace than the rest of the world...."

European Climate At Mercy of Retreating Sea Ice. Following up on the research above here's additional perspective from Gizmag: "An international team of scientists has found that retreating sea ice between the Atlantic and Arctic Oceans is linked to weakened air-sea heat exchange in the region.

Cool, Comfortable Rut: Maps Look More Like May Than July

Toasted, not Burnt

"Deep summer is when laziness finds respectability" riffed Sam Keen. With a few notable exceptions (Monday's "hailers" come to mind) it's been quiet and lukewarm. No fuss. No drama. Summer the way
it was meant to be.

The drought is over - farmers as content as they're ever going to get - and we have yet to see newsworthy levels of heat and humidity. Get used to it.

This is turning into "The Perfect Summer" with just enough warmth for the lake or pool but no debilitating heatwaves or outrageous dew points. Staring at the weather models I still don't see a hot front into mid-July.

The hottest weather of the year usually comes in mid-July, about 3 weeks after the Summer Solstice; there's a built-in "lag" in the atmosphere. Could we still see 90s in late July and August? Absolutely.

But the same persistent ridge of hot, dry air sparking hundreds of wildfires in Alaska and Washington State, and historic drought for California, is turning our prevailing winds to the northwest, with a fresh supply of Canadian air every couple of days. Smoke too.

That milky sky draped overhead is a smoke plume from fires thousands of miles upwind.<p>Oh, the 4th of July still looks great; plan for Sunday T-storms.


More May Than July. It's July, at least on paper. Mother Nature hasn't gotten the memo yet. As far as the atmosphere is concerned we're stuck in early or mid May. I'm not complaining; I don't miss the 90s one bit, but once again the pattern is stuck; the bloated ridge stretching from San Diego to Anchorage continues to dominate the weather across North America, pushing our winds around to the northwest every 2-3 days, pulling another puff of cooler, drier air into Minnesota - and I don't see any evidence the core of the heat will push east anytime soon. The 4th of July still looks miraculously nice with warm sun and low 80s. Watch for T-storms rumbling in Sunday; followed by highs in the 70s to near 80 much of next week.


240 Hour Extended Outlook. Here is NOAA's GFS model looking out 10 days, showing a nice Saturday with southerly winds and temperatures near normal under a hazy blue sky. Showers and T-storms arrive Sunday, with a cooling trend much of next week.


Mid-July: Moderately Warm. Not hot, not here in the Upper Midwest, but if the GFS 500 mb forecast comes close to verifying much of the west and southern USA will be sizzling by mid July, which is - historically - the hottest time of the year, nationwide. Source: GrADS:COLA/IGES.


July 4 Fireworks Spark Astonishing Spike In Air Pollution, NOAA Study Finds. Here's an excerpt of a fascinating story at The Washington Post: "Every July 4, the 14,000-plus dazzling fireworks displays across the nation have a toxic effect on our atmosphere. A new NOAA study shows they temporarily increase particulate pollution by an average of 42 percent. The first of its kind study, published in the journal Atmospheric Environment, analyzed concentrations of fine particulate matter (PM2.5) at 315 U.S. air quality monitoring stations between 1999 and 2013..."

Smoke From Alaska and Canada Fires Dives into Continental USA. Yes, that was smoke dimming the sun yesterday, from fires thousands of miles upwind. Details from NOAA: "The InciWeb Incident Information System is following 18 fires in Alaska that are contributing, along with 49 uncontrolled fires under surveillance by the Canadian Wildland Fire Information System, to vast areas of visible smoke throughout Canadian provinces and stretching into northern U.S. states. This image from the Suomi NPP satellite's VIIRS instrument was taken from NOAA View on June 28, 2015. The smoke from these fires can also be seen in NOAA View as Aerosol Optical Thickness, a measure of how aerosols, such as smoke from wildfires, scatter and absorb sunlight." (Image: NOAA/NASA).


Is Major League Baseball Taking Storms Seriously Enough. Probably not. Meteorologist Craig Edwards is the former MIC (Meteorologist in Charge) of the Twin Cities National Weather Service. He attends every Twins home game, making sure they get the weather call right, protecting fans and players from lightning, hail and damaging winds. But other stadiums? I would be surprised if they take the same precautions. It was a close call in St. Louis Sunday night. Here's an excerpt of a Jason Samenow story at The Capital Weather Gang: "...If a tornado warning is issued when fans are in the stadium, does each park have a plan to quickly evacuate the stands and adequately shelter fans? Can it get fans underground or inside interior rooms (like bathrooms)? In other words, does every tornado-vulnerable stadium have tornado shelters that are well-labeled (like some airports do, like Denver)? MLB has a responsibility to have very good, thoughtful answers to these questions in the vital interest of its fans safety."

Strong El Nino Expected To Linger Into Winter of 2015-2016. Will we enjoy another relatively mild winter? All El Nino events are different, but the majority of these warm phases in the Pacific do correlate with slightly warmer winters for Minnesota, the Dakotas and Pacific Northwest. According to NOAA there's a 90% chance the current (strong) El Nino will linger into autumn; an 85% chance it will carry over into next winter.


Lightning Deaths So Far In 2015. Here's an NOAA update on lightning fatalities so far this; a majority of deaths from people near trees, on rooftops or boats. You don't want to be near tall objects and you certainly want to avoid open areas like fields, lakes, fields or golf courses, where you may be the tallest thing in the area. The best advice: when you hear the first growl of thunder (or see storms approaching on a Doppler app on your phone) head inside - a building or even a vehicle offers sufficient protection from lightning.


Hurricane Planes Get Overhaul As NOAA Eyes Next Generation. Just like the military expect an accelerated transition to drones in the years ahead. Here's an excerpt of a story from Tampa Tribune at TBO.com: "Miss Piggy is flying again. But even as the lumbering P-3 Orion aircraft takes part in its first mission since getting two new engines in a life-extending overhaul, the National Oceanic and Atmospheric Administration is looking for the next generation of hurricane hunting aircraft. Miss Piggy and NOAA’s other Orion, named Kermit, are stationed at MacDill Air Force Base. Each plane was put into service during the mid-70s and has flown more than 10,000 hours, into more than 80 hurricanes. They are long, grueling missions, often subjecting the crew to zero gravity as the aircraft lurch up and down in buffeting winds. With the pounding they’ve taken, the planes need the $42 million refurbishing to stay on the job during the June through November hurricane season and beyond..."

The Perils of Weather Prediction. Think the forecasts are bad now? It's a step up from what passed for weather forecasts in the 18th and 19th centuries. Here's an excerpt of an interesting article at The Daily Beast: "Growing up, I was advised that one of the better careers to seek out was that of weatherman—they managed to get plenty wrong and yet keep their jobs. In reality, the modern weather prediction we largely take for granted is pretty reliable, certainly when contrasted with conditions two centuries ago, when even the slightest degree of predictability was utterly impossible. The tortuous and heated chase to understand—and predict—the weather is the tale Peter Moore tells in his fascinating new book, The Weather Experiment: The Pioneers Who Sought to See the Future..."


The Underfunded, Disorganized Plan To Save Earth From The Next Giant Asteroid. OK. I officially have enough to worry about now - no wonder I wander the land in a perpetual state of paranoia. Here's an excerpt from Motherboard: "...After this arguably close brush with total annihilation, Congress asked NASA to prepare a report on the threat posed by asteroids. The 1992 document, "The Spaceguard Survey: Report of the NASA International Near-Earth-Object Detection Workshop," was, suffice it to say, rather bleak. If a large NEO were to hit Earth, the report said, its denizens could look forward to acid rain, firestorms, and an impact winter induced by dust being thrown miles into the stratosphere. In the initial moments following impact, the impact site—which is generally 10 to 15 times the size of the asteroid—would be vaporized..."

Of Course Climate Change Is A Moral Issue.

By recklessly pumping greenhouse gases into the atmosphere, we are wounding creation itself. And those who have contributed least to carbon pollution, the poor, will increasingly suffer the most from it effects, while those in the future will inherit a degraded and dangerous environment. If we value creation and if we feel moral responsibility to our fellow humans, we need to take actions to dramatically reduce greenhouse gases and reshape our economy so that it does not imperil the planet..."

Pope's Activism Sets Stage For Awkward Visit To Capitol Hill. The Hill has the story; here's the introduction: "Congressional Republicans say they are ready to welcome Pope Francis to Capitol Hill this fall — even if he uses part of his speech to challenge them on issues like climate change or income inequality. Francis’s climate change encyclical last week was just the latest example of his willingness to wade into contentious political debates, often with positions that seem to fall on the liberal side of the spectrum. The pope’s nods to progressive politics have put some Republicans in an awkward spot. While many are Catholic and conservative, they are loath to be seen as criticizing the head of the church..."


Will Catholic Republicans Side With The Pope on Climate Change? Here's a snippet from a story at The Washington Post: "... Are Catholics likely to change their views on climate change in order to align with Pope Francis? For some hints, it may be helpful to look at the shift in how Catholics viewed the death penalty following the Catholic Church’s involvement more than two decades ago. There is evidence that links an uptick in Catholics opposing capital punishment after Pope John Paul II issued an encyclical that discouraged the use of the death penalty in 1995. One study found that support for the death penalty had been higher among Catholics than non-Catholics in the 1970’s; by 2004 the opposite was true..."

Isolating The Underlying Causes of Extreme Weather. Here's a shocker: it's related to continued warming of the planet; we're putting more energy into the climate system and then acting surprised and indignant when the weather bites back. Here's an excerpt summarizing new research at Stanford University: "...Worldwide news reports of extreme weather events – oppressive heat, parching droughts, destructive storms – are increasingly common. A new study co-authored by Stanford and Princeton University researchers finds that trends in atmospheric circulation patterns can partially explain Earth’s increasingly severe weather. While scientists had previously surmised that the link existed, robust empirical evidence was lacking. The study finds that overall increases in hot extremes and decreases in cold extremes in the Northern Hemisphere mid-latitudes are driven by a combination of changes in the amount of heat and moisture in the atmosphere as well as changes in atmospheric circulation patterns. Changes in the heat and moisture content of the climate system – called “thermodynamics” – can account for the majority of the observed changes in extreme temperature..."
