Hint of Dog Days
"Ah, summer, what power you have to make us suffer and like it" said Russell Baker. Except for a Bangladesh-like June and a few severe wind episodes there hasn't been all that much suffering this summer.
I still don't see anything resembling an old-fashioned heat wave but, with high confidence, I can predict that neighbors and complete strangers will be griping about drippy dew points within a few days - forecast to hold near 70F from Saturday into most of next week.
That's one of the trends we're tracking: summers aren't appreciably hotter on average in Minnesota (the real warming signal is showing up in winter, especially at night), but dew points are running consistently higher. Warmer air can hold more water vapor, meaning higher humidity levels; more moisture available to spark extreme rain events.
The heaviest T-storms should track south of Minnesota into the weekend; a relatively dry spell with temperatures in the 80s - even a shot at 90F next week. More like mid-July.
In today's weather blog: America's low-orbiting weather satellites may be in trouble. And new research confirms an uptick in extreme weather; odd jet stream gyrations that cause the weather to become "stuck".
A Minor Case of the Dog Days. Soak up the low dew points, because it'll feel like early July again by late week, with tropical air lingering into next week. Highs will reach the mid-80s, and I could see a 90F or two next week. The arrival of this steamy warm front sets off isolated T-showers Friday into Sunday, a better chance of T-storms by the middle of next week.
Super Soakers Push Across New England. The same front that flooded much of Detroit and Baltimore will push heavy T-storms across New England today, enough rain for flash flooding in some communities. Monsoonal T-storms pop up from near Phoenix to Salt Lake City, a few random storms flaring up over the Pacific Northwest. 60-hour WRF Future Radar courtesy of NOAA and HAMweather.
More Like June. By August the atmosphere should be stabilizing with fewer thunderstorms capable of severe weather and flash flooding. Tell that to residents of the Northeast, where some 2-5" rains are possible again today. Dry weather dominates over the central USA, locally heavy rain over the Rockies from late afternoon instabilty T-storms. 60-hour WRF rainfall totals: NOAA and HAMweather.
"Unprecedented" Flooding Event in Detroit Fits Global Warming Pattern. Meteorologist Andrew Freedman has the story at Mashable; here's an excerpt that caught my eye: "...Paul Gross, chief meteorologist for WDIV-TV in Detroit, that the event was absolutely unprecedented in his long career in the city.
I have lived my entire life and worked my entire career here, and I have never seen as widespread a flooding event. Yes, I vividly remember the May 2004 historic month of rain — our second wettest month ever with 8.46 inches of rain — but that was a bunch of rainy days that really added up.
I also remember some individual intense thunderstorms that flooded ONE freeway. But I don't ever remember EVERY freeway being flooded out.
The storm, which is likely to have caused tens of millions in damage to a city that is already struggling economically, is an example of the type of event that is already occurring more frequently and severely due to manmade global warming..."

Extreme Weather Becoming More Common, Study Says. Details of the new paper are below (in the climate story section), but it shows the possible link between large-scale, long-term climate shifts and day to day weather. So far there is correlation, but no causation, no final smoking gun proving the link. Here's an excerpt from The Guardian: "..Climate scientists in Germany noticed that since 2000 there have been an “exceptional number of summer weather extremes, some causing massive damage to society”. So they examined the huge meanders in the high-level jet stream winds that dominate the weather at mid-latitudes, by analysing 35 years of wind data amassed from satellites, ships, weather stations and meteorological balloons. They found that blocking patterns, which occur when these meanders slow down, have happened far more frequently. “Since 2000, we have seen a cluster of these events. When these high-altitude waves become quasi-stationary, then we see more extreme weather at the surface,” said Dr Dim Coumou, at the Potsdam Institute for Climate Impact Research. “It is especially noticeable for heat extremes...”
Extreme Summer Heat, Rain On Rise As Weather Gets Trapped - Study. Picking up on the new research released Monday here's a slightly different perspective from Reuters: "...We are warming our atmosphere by emitting carbon dioxide from fossil fuels, but the increase in devastating heatwaves in regions like Europe or the U.S. seems disproportionate," lead author Dim Coumou said in a statement. Climate change was disrupting the flow of the jet stream, which blows from west to east around the Earth and forms waves high in the atmosphere that can be thousands of km (miles) from crest to crest. "In periods with extreme weather, some of these waves become virtually stalled and greatly amplified," it said. "While a few days have little impact, effects on people and ecosystems can be severe when these periods are prolonged..."
California Drought: San Francisco Poised To Require Water Rationing. SFGate has the story - here's the introduction: "San Francisco water users would be forced to reduce outdoor watering by 10 percent - or face penalties - under a proposal by utility officials who are poised to add the city to a growing number of California communities that are rationing water amid one the worst droughts in decades....It would apply primarily to large customers who use the bulk of their water outdoors, like schools, golf courses, shopping centers and condo complexes..."

"Remarkable" Warming Reported in Central California Coastal Waters. Here's an excerpt from The Los Angeles Times: "...The upper ocean within 50 to 100 miles of the coast has been 3.6 to about 7 degrees Fahrenheit warmer than what’s typical for this time of year, mostly south of the Golden Gate, he said. “Scientists and many others that are interested in our ocean are paying close attention to this warming because it will likely impact marine life, and it could impact marine life beyond this summer,” he said..."

Sweden's Massive Forest Fire Lit By Record Temperatures. Nature World News has more details on the highly unusual wildfire impacting Sweden; here's a clip: "...As of August 7, the fire was deemed a national emergency, and the Swedish Armed Forces was mobilized to aid firefighters and help facilitate an orderly evacuation of affected and threatened areas. A fire of this size is extremely uncommon in Sweden, which traditionally experiences fores fires that encompass a few square miles at most, according to the International Forest Fire News. In fact, fires are so rare in the region that the Swedish movement actually prescribes controlled burning of old and dried brush to promote healthier woods..."
Photo credit above: "A massive forest fire in Sweden has been raging for 11 days, and has grown into the largest fire the country has seen within the last four decades. This fire is occurring in the wake of the highest temperatures Sweden has ever experienced on record, and experts are quick to point out that this is no coincidence." (Photo : USDA)
The Legacy of Florida's Year of Four Hurricanes. The Orlando Sentinel has a good recap of a very crazy year: 2004. Here's a clip: "For six weeks, Florida reeled under the assault of four hurricanes. First Charley struck Port Charlotte Aug. 13, 2004, with 150-mph winds. It blasted its way into Central Florida five hours later with winds clocked at 105 mph at Orlando International Airport. Hurricane Frances followed on Sept. 5 with lashing winds and drenching rains that would total 14 inches in metro Orlando. Tree limbs tore down power lines. Roofs were peeled from homes. Thousands sweltered without electricity. Then Ivan came ashore near Pensacola with 120-mile-per-hour winds and a storm surge that swamped coastal towns. And Jeanne struck the same area as Frances on Sept. 25, adding insult to injury..."

America's Weather-Tracking Satellites Are In Trouble. It's the low-earth satellites that are triggering the greatest concern; here's an excerpt of a good overview from Popular Mechanics: "...Those polar-orbiting satellites, a primary and its backup, are the ones in crisis. The primary satellite—a short-term pathfinder built to test emerging technologies—was never really intended for use. Its backup isn't much better: an aging satellite with failing sensors that passed its predicted life expectancy last year. We would send up a replacement now, but it's still being built. When it is ready, should it survive launch, it could take until as late as 2018 to transmit usable data. Which means that, depending on when our current satellites stop working, the U.S. could be without crucial data for years. That's worse than inconvenient. It could cost us trillions of dollars, and hundreds, if not thousands, of lives..."

"Massive Florida Red Tide" Is Now 90 Miles Long and 60 Miles Wide. C'mon kids - let's go swim in the red ocean! What is going on off the southwest coast of Florida? Here's an excerpt from The Los Angeles Times: "There's a massive red tide blooming off the coast of southwestern Florida and it appears to be growing. The red tide is patchy, but researchers say it stretches an amazing 60 miles wide and 90 miles long in the Gulf of Mexico. Just a few weeks ago it was reported to be 50 miles wide and 80 miles long. Even at its new size it's not the most colossal bloom recorded in this part of the world, but it is the biggest since 2005, according to Hayley Rutger, a spokeswoman with Mote Marine Laboratory and Aquarium..."

Can Weather Patterns Help Predict Disease Outbreaks? Here's an excerpt of an interesting story and video at CNN: "Scientists and meteorologists are able to predict the weather - could they apply the same technology to predicting epidemics like Ebola? Carlos Watson, co-founder and editor of OZY, appeared on "New Day" Friday to discuss the efficacy of climate change data and technology, and how it could prevent future outbreaks. Researchers have found that there could be correlations between weather patterns and the development of disease in a specific region..."
U.S. Capability To Respond To The Next Great Disaster. As populations continue to grow, with more people living in (vulnerable) regions near rivers and sea level, the potential for major disasters continues to increase. Here's a story from a story pondering hypotheticals at The Brookings Institution: "..But as global populations grow, especially along the Asian littoral, and as certain storms or large-scale weather patterns are perhaps intensified or at least shifted by climate change we need to be ready for worse. Superimposing the bands of devastation from some of the above on more populated areas helps one see the realm of the plausible. What if the Fukushima nuclear accident had affected reactors near Tokyo, with its population of some 30 million? What if a future Typhoon Haiyan targets Shanghai? What if a massive earthquake hit Karachi, Pakistan or sent a tsunami into the heavily populated areas of coastal East Asia?..."

Is Sunscreen a Lifesaver or a Poison? Or does it lull us into receiving far more sunshine than we really should? Everything in moderation, right? Here's an excerpt of an interesting story that had me running for shade at FiveThirtyEight: "... People who are fair-skinned have higher skin cancer rates, and their pigmentation matters more than where they live. What is less well established, at least in the data, is whether sunscreen mitigates these risks. The theory behind sunscreen is very sound. Sunscreen absorbs UV light, blocking it from reaching the skin, and UV light exposure is linked with cancer. In practice, however, the evidence on the relationship between sunscreen use and skin cancer is more limited..."
How Weather and Climate Models Work - Or Why Meteorologists Learn Calculus. Yes, I still have nightmares about Math 102, "Advanced Partial Differential Equations". Nasty stuff (and I still can't balance my checkbook). Here's an excerpt of a good explainer from Dan Satterfield at AGU, The American Geophysical Union: "Numerical weather models have come light years over the last 30 years, and despite what you may think, they make it possible to make very accurate weather forecasts for as much as 5-7 days into the future possible. Have you ever wondered just how they work? It’s not something that you can cover in a few paragraphs, but it is not all that hard to get a basic understanding of how it’s done, and if you will give yourself 50 minutes and pay attention, you will (I hope) find it very fascinating. You will also not just see greek when you see an equation like this somewhere!..."
How To Cover The Robin Williams Story Responsibly. Borrow a term and concept from physicians, the Hippocratic Oath: "...but first, do no harm". I thought Al Tompkins brought up some very good points in a recent article at Poynter - here's an excerpt that caught my eye: "...One of the most common mistakes that journalists can make in covering suicide is to advance the notion that one big thing caused someone to take their life. Suicide is a complex response that usually involves lots of factors including mental illness. In fact, suicide experts estimate 90 percent of suicides have some connection to mental illness and/or substance abuse. Both are treatable..."
"...The truth is that depression has nothing to do with bravery or courage. It is a monster that strips those traits away before it even gets warmed up. If anything, Robin Williams' suicide is another reminder that all the talent and humor in the world is no match for the power and darkness of depression. The way I see it, if you can fight off depression for 63 years and make others laugh and feel good, you are one courageous dude...." - Dave Pell, author of NextDraft.
Dealing With Depression. On Monday SAVE (suicide awareness - voices of education) had it's annual golf tournament at the TPC Course in Blaine. Many of the golfers and sponsors have had first-hand experience with the ravages of suicide, and were there to support prevention efforts, finding new ways to get a critical message out: mental health issues tend to be ignored until it's too late. There are treatments and medications that can help people struggling with depression. News of Robin Williams taking his life struck like a thunderbolt, and it highlighted the reality: it doesn't matter if you're rich or poor, famous or infamous - depression can strike anyone. It's up to us to search for symptoms, be aware, and get the people we care about the help they need - in time. Here's more from SAVE, based on Bloomington, with an international outreach:
"SAVE is saddened to hear about the passing of Actor Robin Williams and expresses our condolences to his family and friends. At SAVE we know well the tragedy of suicide and the impact it has on everyone. It you would like to know more about how to prevent suicide, we have information on the warning signs and what you can do to help someone. If you are struggling with thoughts of suicide or harming yourself, please call us (7283) or you can reach out to the National Suicide Prevention Lifeline at (8255) 24 hours a day / 7 days a week..."

"...I’ve said it before, and I’ll say it again; dismissing the concerns of a genuine depression sufferer on the grounds that you’ve been miserable and got over it is like dismissing the issues faced by someone who’s had to have their arm amputated because you once had a paper cut and it didn’t bother you. Depression is a genuine debilitating condition, and being in “a bit of a funk” isn’t..." - Dean Burnett at The Guardian.
Hit The Reset Button On Your Brain. Our businesses and friendships often require that we stay connected to The Matrix, but our long-term mental health requires that we disconnect and give our brains a break; so argues an important story and study highlighted at The New York Times; here's a clip: "...Every status update you read on Facebook, every tweet or text message you get from a friend, is competing for resources in your brain with important things like whether to put your savings in stocks or bonds, where you left your passport or how best to reconcile with a close friend you just had an argument with. If you want to be more productive and creative, and to have more energy, the science dictates that you should partition your day into project periods. Your social networking should be done during a designated time, not as constant interruptions to your day..."

Arctic Methane Could Accelerate Climate Change. Unknown unknowns. We like to think, as a species, that we know all the various paths the future might take, but when it comes to climate and potential tipping points...we don't know nearly as much as we think we know. Here's a clip from The Green Optimist: "...Unfortunately, climate change due to rising CO2 levels is generating a spiral effect, a positive feedback loop, which could lead us to a dangerous situation. Dr. Box colorfully notes that, if even a fraction of Arctic carbon is released, we’re “f-bombed as a species.” The problem is that warmer temperatures are increasing the temperatures of ocean currents, as well as air currents, which is leading to melting ice caps, permafrost, and the undesirable effects that these generate in their own turn. For example, some theorize that the recent hole that opened up in the Yamal Peninsula, Northern Russia, could actually have been caused by a collapsed pingo, that is, melted permafrost leaving a cavity, which caved in. It may also have been accompanied by a release of natural gas, which is commonly found in the area..."
Tom Skilling on Climate Change. Chicago Tonight at WTTW-TV has an interview with one of the best TV meteorologists on the planet, Tom Skilling (and a great guy too). Here's an excerpt: "...You know, I’m often asked why scientists only focus on the negative aspects? If you look at both human society and ecosystems, they’ve both adapted to changes in the climate when the changes are little. The changes we’re seeing now are occurring 10 times faster. A rapid change makes it difficult for both ecosystems and human societies to adapt to it..."
Ebola and Climate Change: Are Humans Responsible for the Severity of the Current Outbreak? Alarmist hype? Maybe. Newsweek has the story that attempts to connect the dots; here's a clip: "...Humans are the major driver of emerging diseases,” says Jonathan Epstein, an epidemiologist at the non-profit EcoHealth Alliance who studies Ebola and other infectious disease. “Things like agricultural expansion and deforestation...and certainly travel and trade — these are things that manipulate our environment and allow pathogens to get from animal hosts to people and then travel around the world.” In a study published in 2012, researchers asked national infectious disease experts in 30 different countries whether or not they thought climate change would affect infectious disease patterns in their countries. The majority agreed..."
Don't Believe The Hype. 5 Reasons To Be Pessimistic About Climate Change. I have my moments of pessimism - can we, as a global society, really get our arms around this problem in time, in a concerted, thoughtful way that won't wreck the economy? This will be our Moon Shot and Manhattan Project rolled into one for the 21st century. Here's an excerpt of a more downbeat assessment at The Week: "...While the EPA's new regulations on power plants are a welcome first step, they are not carved in stone. The EPA will likely face numerous legal and legislative challenges before its rules are implemented. Meanwhile, climate change denial remains the mainstay of a significant portion of one half of the American political spectrum. Messaging aimed at muddying the waters — of both the science of climate change and the political imperative in tackling it — has not abated. As Slate's Will Oremus has reported, deniers are now willing to acknowledge some aspects of the scientific reality, but are quick to interject that the cure will be worse than the disease..."

Quasi-Resonant Circulation Regimes and Hemispheric Synchronization of Extreme Weather in Boreal Summer. It's a long title for a fairly straightforward concept, a symptom of rapid warming, especially at northern latitudes, which may be impacting the wavelength of global Rossby waves, creating conditions more favorable for an elongated (high amplitude) jet stream, one more prone to extreme weather, severe heat and excessive rains. For several years I've been wondering if it was my imagination, if we really were seeing tangible evidence of a more amplified jet stream capable of more frequent weather extremes over the Northern Hemisphere? Or was there hard data - research, to back up these observations? Here's a summary of a technical, but very important new paper from Coumou, Petoukhov, Rahmstorf, Petri and Schellnhuber at PNAS.org: "...The recent decade has seen an exceptional number of boreal summer weather extremes, some causing massive damage to society. There is strong scientific debate about the underlying causes of these events. We show that high-amplitude, quasi-stationary Rossby waves, associated with resonance circulation regimes, lead to persistent surface weather conditions and therefore to midlatitude synchronization of extreme heat and reainfall events. Since the onset of rapid Arctic amplification around 2000, a cluster of resonance circulation regimes is observed involving wave numbers 7 and 8. This has resulted in a statisticially significant increase in the frequency of high-amplitude quasi-stationary waves with these wave numbers. Our findings provide important insights regarding the link between Arctic changes and midlatitude extremes..."
