Sunday Heat Spike? After reaching upper 80s Saturday (morning clouds and T-storms keeping us a few degrees cooler than we would be otherwise) we break out into a sunny airmass on the hot side of the front Sunday. Models are already hinting at mid 90s, and some upper 90s can’t be ruled out, especially south/west of the Twin Cities. Graph: Iowa State.
Advancing Hot Front. The 84 hour NAM model (NOAA) shows comfortable high pressure over New England into the weekend, but a bulging ridge of high pressure pushes intense heat across the Plains into the Midwest, boosting the mercury well into the 90s by Sunday. Cabo San Lucas may see heavy rain from a developing tropical storm off the coast of Baja Mexico.
Uh Oh. This is starting to feel a little like last summer: starting (very) wet, then going over a rainfall cliff by August. According to the Drought Monitor Minnesota has gone from 1.7% moderate drought to 10.11% moderate drought as of August 20. Most of the state is now designated as “abnormally dry”. Remind me not to complain about a few random T-storms Saturday morning, because rainfall next week will be spotty and sparse.
Could A Hurricane Ever Strike Southern California? The answer is yes, although the risk is very low due to upwelling of chilly Pacific Ocean water. Generally water temperatures need to be 80-81 F. for hurricane development. As anyone who has ever taken a dip in the Pacific will confirm, water temperatures are usually in the 50s, maybe low 60s off the coast of L.A. and San Diego. During an extreme El Nino it’s conceivable that water could remain (just) warm enough to support a hurricane pushing into southern California. Here’s an excerpt of a post from NASA: “There’s an old adage (with several variations) that California has four seasons: earthquake, fire, flood and drought. While Californians happily cede the title of Hurricane Capital of America to U.S. East and Gulf coasters, every once in a while, Mother Nature sends a reminder to Southern Californians that they are not completely immune to the whims of tropical cyclones. Typically, this takes the form of rainfall from the remnants of a tropical cyclone in the eastern Pacific, as happened recently when the remnants of Hurricane John brought rain and thunderstorms to parts of Southern California. But could a hurricane ever make landfall in Southern California? The answer, as it turns out, is yes, and no. While there has never been a documented case of a hurricane making landfall in California, the Golden State has had its share of run-ins and close calls with tropical cyclones. In fact, California has been affected by at least a few tropical cyclones in every decade since 1900. Over that timeframe, three of those storms brought gale-force winds to California: an unnamed California tropical storm in 1939, Kathleen in 1976 and Nora in 1997. But the primary threat from California tropical cyclones isn’t winds or storm surge. It’s rainfall — sometimes torrential — which has led to flooding, damage and, occasionally, casualties…”

California Hurricane? Highly Unlikely, But Not Impossible. In fact it almost happened in 1997 with Hurricane Linda. Today’s Climate Matters looks at why the West Coast doesn’t see hurricanes (as a rule) and how an expanding heat bubble over the USA may ultimately increase the potential for Atlantic hurricanes by September: “WeatherNationTV Chief Meteorologist Paul Douglas goes over some late season hurricane climatology. Also, what are the chance that a tropical storm hits California? How does the heat bubble baking the Central Plains and Midwest play into late season tropical storms?”
2013 Hurricane Season A Bust? Not So Fast. It’s a little premature for complacency for anyone living in or near Hurricane Alley. Here’s a clip from a story and video at floridatoday.com: “Almost halfway finished, the 2013 hurricane season has been a breeze in Florida. But Craig Fugate, the federal government’s top emergency manager, looks at things a little differently. His question: “Have we started playing college football yet?” Fugate and Bryan Koon, director of the state Division of Emergency Management, held a news conference Wednesday to reinforce the message that Florida is just entering the thick of hurricane season in late August and September — which, coincidentally is when college football starts.”

Atlantic Basin Primed For An Above-Normal Hurricane Season. Yes, it’s very quiet out there – and we have yet to see our first hurricane of the season in the Atlantic. Based on a variety of factors (less Saharan dust, warmer water temperatures, low wind shear) I suspect September will be a lot busier than August has been. More details from NOAA’s Climate.gov: “Andrea, Barry, Chantal, Dorian, Erin*… who’s next? Probably plenty more, according to NOAA’s updated Atlantic hurricane season outlook. With five named storms already in the books this summer, the 2013 hurricane season is shaping up to be above normal, and there is a possibility that it could be very active during the peak of the season from mid-August through October. An additional 9-15 named storms are likely, of which 6-9 are predicted to become hurricanes, with 3-5 reaching major hurricane status. Among the climate factors behind the heightened activity? Heat. These maps show the tropical cyclone heat potential of the tropical Atlantic Ocean ramping up between May 24 (bottom) and August 4 (top). This “hurricane heat potential” depends not just on the surface temperature, but on the depth of the warm water…”
National Hurricane Center Gives Storm Surge Modeling A Major Boost. Here’s a clip from an interesting story at The Washington Post’s Capital Weather Gang: “The National Hurricane Center (NHC) is running an improved version of its old, reliable storm surge model on faster computers to help emergency managers update hurricane evacuation plans. When a storm threatens any place in the U.S. NHC forecasters will use the improved, faster-running model to predict its surge. Hurricane forecasters know those who might be in a hurricane’s path tend to focus on the storm’s wind speed, which define its one-to-five category. “The categories put a focus on wind; people are absorbed by wind,” says Jamie Rhome, the NHC’s storm surge lead, but “water is what kills the vast majority of people. Evacuations are done for surge…”

July: 341st Month/Row Of Warmer Than Average Global Temperatures. Meteorologist Andrew Freedman has the story at Climate Central; here’s a clip: “The year-to-date has been the sixth warmest on record globally, and July was also the sixth warmest such month since global surface temperature records first began in 1880, according to new data released on Tuesday by the National Oceanic and Atmospheric Administration (NOAA). The figures show that July 2013 was the 37th straight July, and the 341st straight month, with warmer-than-average global temperatures — a more than 28-year timespan that reflects the significant warming observed worldwide since the 1970s. That means that no one under the age of 28 has ever experienced a month in which global average surface temperatures were cooler than average (based on the 20th century average)…”
Apple, Closer To Its Vision For A TV Set, Wants ESPN, HBO and Viacom, and Others To Come Along. Will Apple ever come out with a TV? Timing (and content deals) are everything. Here’s a clip from a good story at Quartz: “Years of halting negotiations with cable companies haven’t gotten Apple much closer to its grand vision for television. But a newer strategy of talking directly to content providers seems more promising. Apple is negotiating with production studios and networks to provide content for a television set that would emphasize apps over cable TV, according to people familiar with those discussions. Among the companies that have talked to Apple are Disney’s ESPN, Time Warner’s HBO, and Viacom, which owns MTV Networks, Nickelodeon, and Comedy Central. It’s unclear how close these deals are to fruition. Some people cautioned that, with the TV industry in such flux, “everybody is talking with everybody.” Any deal with an internet TV service like the one envisioned by Apple is likely to be under similar terms as the networks have negotiated with traditional cable companies…”

Hollywood And Steroids: When A-List Actors Go The A-Rod Route. I’m just waiting for a story to come out about steroid use in the meteorological industry. I have some questions about Al Roker. In the meantime here’s an excerpt from a fascinating read at The Hollywood Reporter: “In 2005, a 30-something actor on the precipice of superstardom began prepping for a lead feature role that required ample spotlight on his abs. The actor met with the film’s trainer and outlined the performance-enhancing drugs, including human growth hormone (HGH), he already had been taking. The trainer, a firm believer that a chiseled physique should be achieved naturally, recused himself from working with the actor. “He told me that HGH made him feel like nothing else ever made him feel,” recalls the trainer, who declined to be identified out of respect for trainer/trainee confidentiality. “He was basically addicted. I told him to find another trainer. He did…”

Bismarck Is Lovely This Time Of Year. Really. The thrust of this story (which makes a lot of sense to me) is: people need to MOVE to where the jobs are! Easier said than done, with kids in school and care for parents, not to mention moving away from friends. Here’s a clip from a story at Slate: “…Of course there are always good reasons not to move. Midland, Texas (3.7 percent) is remote. Minneapolis (5.1 percent) is cold. Honolulu (4.7 percent) is expensive. Morgantown, W.V. (4.5 percent) is small. And Bismarck, N.D.—America’s unemployment rate champion, at just 2.8 percent—managed to be remote, cold, expensive, and small all at once. Meanwhile, areas with even the most hopeless economies might offer good cause to stay. People may have relatives to look after in their hometown, or else depend on relatives to take care of their kids. People have friends and family. They have financial and personal commitments. Moving is expensive, and moving to a new pace where you don’t have a job lined up is scary. Ask any given person in any given town why they don’t move to some other town, and the list of reasons will be endless…”

What Your Ikea Chair Says About You. I found this vaguely interesting – here’s a clip from priceonomics.com: “…This means that our surrounding environments may strongly influence our feelings and behaviours. A forthcoming paper from researchers at MIT, Columbia, Northwestern, Harvard, and Berkeley investigates whether something as simple as the size of our chair or workspace can nudge us toward dishonesty. The study, entitled “The Ergonomics of Dishonesty: The Effect of Incidental Posture on Stealing, Cheating, and Traffic Violations,” begins by citing academic research on the link between posture and thoughts, feelings, and social status. In a terrifyingly offhand manner, they also cite research showing that power “appears to be linked to increases in a wide range of dishonest behaviors.” The theoretical ground for their idea established, they ask whether manipulating the physical environment can induce people to act less honestly…”
7 Life Secrets Of Centenarians. Want to live to be 100 years old? Let me think about that. Here’s an excerpt of an interesting story at PBS’s Next Avenue: “…To be sure, these centenarians are among the best, brightest and healthiest of the current class; that’s what makes them role models for the future of aging. Here are seven secrets they cite for living a long and happy life.
1. A Positive Attitude Trudi Fletcher of Tubac, Ariz., a lifelong artist, remains an innovative painter at 100 and recently had a gallery exhibition showing off her new style. She credits her creative longevity to “attitude, attitude, attitude.” Almost all of the centenarians we spoke to believe a positive yet realistic attitude is critical throughout one’s life and described themselves as optimistic people.
2. Diet Here’s diet advice you may not have heard before: Eat like it’s 1960. Our centenarians were critical of today’s supersized portions; the majority advised just eating nutritious food in moderation. Only 20 percent said they had ever been on a specialized diet plan, although some had become vegetarians. Lillian Cox, 107, of Tallahassee, Fla., confided that in her 50s she became “quite heavy” but resolved to lose the weight, did so and kept it off by just eating less. The stylish former dress shop owner says, “I was a good advertisement for the merchandise I selected on my frequent buying trips to New York…”
How Far Do You Run Playing Different Sports. By Gizmodo’s calculations, during a typical pro basketball game, about 2.72 miles, compared with 1.25 miles for an average NFL football game (11 whole minutes of action!) Here’s an excerpt of the story: “While watching sports, have you ever stopped (midway through a bowl of Cheetos) to wonder, “How far are those guys actually running?” It’s a common question, one that’s historically been subject mostly to guesswork, Thanks to some recent technological developments, though, we can now actually apply some data to it.

Rising Seas. This is the cover story for September’s National Geographic; here’s a snippet of the online version, courtesy of NatGeo: “…Global warming affects sea level in two ways. About a third of its current rise comes from thermal expansion—from the fact that water grows in volume as it warms. The rest comes from the melting of ice on land. So far it’s been mostly mountain glaciers, but the big concern for the future is the giant ice sheets in Greenland and Antarctica. Six years ago the Intergovernmental Panel on Climate Change (IPCC) issued a report predicting a maximum of 23 inches of sea-level rise by the end of this century. But that report intentionally omitted the possibility that the ice sheets might flow more rapidly into the sea, on the grounds that the physics of that process was poorly understood. As the IPCC prepares to issue a new report this fall, in which the sea-level forecast is expected to be slightly higher, gaps in ice-sheet science remain. But climate scientists now estimate that Greenland and Antarctica combined have lost on average about 50 cubic miles of ice each year since 1992—roughly 200 billion metric tons of ice annually. Many think sea level will be at least three feet higher than today by 2100. Even that figure might be too low…”
Bloomberg: Why Sandy Forced Cities To Take Lead On Climate Change. Solutions will be slow in coming from our “do as little as possible” Congress. Many of the innovations, the attempts to harden infrastructure and make cities more resilient, will come at a state and local level. Here’s a portion of an Op-Ed from New York City Mayor Michael Bloomberg at CNN: “…Last fall, Hurricane Sandy made all too clear how vitally important it is to build stronger and more sustainable infrastructure that can withstand extreme weather events. That’s why in June, we launched a long-term plan specifically focused on protecting our city from the effects of climate change. For instance, we’re working to strengthen dune systems and beaches across the city. Our plan includes surge barriers to prevent flooding and a strong network of bulkheads, floodwalls, levies, and other protections in vulnerable places along the waterfront. We are working with private companies and regulators to strengthen critical infrastructure against severe weather — including our power, telecommunications, and transportation systems. And we’re also raising construction standards to ensure new buildings can withstand extreme weather...” (Photo: AP, New Jersey Air Force)
Hurricane Enable: How Climate Change Is Mixing Up Bigger, Badder Storms. Atlantic hurricanes are becoming more extreme over time, a nearly doubling of intense, Category 3+ storms since the 1970s. Grist examines the trends; here’s a clip: “…Not only does the heat provide more fuel for devastating hurricanes, like turning up the heat on the pressure cooker, but warmer air above the hotter oceans also holds more water vapor. “That affects all storms: It leads to heavier rainfalls,” Trenberth says. And the effect is not linear. It scales up, making the most powerful storms far stronger. That 1 degree C rise in temperature has led to about 5 percent more water vapor over the Atlantic, but the storms don’t just get 5 percent stronger, Trenberth says. The water vapor “gives the storm extra buoyancy, so you could argue you get as much as a 10 percent increase in the power of the storm.” He estimates that the the real number is probably somewhere in between 5 and 10 percent. These more powerful storms are also riding higher oceans. Globally, sea level has already risen to the tune of eight inches since 1870. In many places, the rise is even greater. Higher baseline sea levels give storm surges a running start...” (Image above: NASA).
Is Climate Change Humanity’s Greatest-Ever Risk Management Failure? Short answer. Probably. Here’s the intro to a post at The Guardian: “Humans are generally very risk-averse. We buy insurance to protect our investments in homes and cars. For those of us who don’t have universal health care, most purchase health insurance. We don’t like taking the chance – however remote – that we could be left unprepared in the event that something bad happens to our homes, cars, or health. Climate change seems to be a major exception to this rule. Managing the risks posed by climate change is not a high priority for the public as a whole, despite the fact that a climate catastrophe this century is a very real possibility, and that such an event would have adverse impacts on all of us. For example, in my job as an environmental risk assessor, if a contaminated site poses a cancer risk to humans of more than 1-in-10,000 to 1-in-1 million, that added risk is deemed unacceptably high and must be reduced…”

A Cosmic Correlation Between Northern Lights And Global Warming? A minimum in the natural solar cycle (and sunspots) might shave global temperatures by a fraction of a degree C, probably not enough to make a dent in gradually warming temperatures worldwide. Here’s a clip from an interesting story at Alaska Dispatch: “What would happen to global warming if the sun quit producing sunspots for a few decades? The question is of more than passing interest to climate scientists as they ponder the prospect that the sun may be about to enter such a period. The coming flip of the sun’s magnetic field in a few months marks the peak of the current sunspot cycle – one that has produced the fewest sunspots in at least 100 years, and perhaps the last 200 years. Peering at trends – or in some cases, the lack of them – in the sun’s behavior during the run-up to the current cycle’s peak, some solar physicists increasingly are considering the possibility that the sun may be on the verge of a “grand solar minimum,” comparable to a 70-year period running from the early 17th century into the early 18th century, when the sun produced no sunspots at all...”
Climate Change: Speaking The Unspeakable. Psychologists tell us that most people refuse to accept a problem for which there is no obvious solution. That’s one of the many challenges with climate change: no silver bullet. But there is a boxful of silver buckshot – thousands of improvements, tweaks and innovations, which in the aggregate, scaled worldwide, can make a difference. The Energy Collective has the story; here’s a clip: “Rosemary Randall, a writer I’ve just encountered for the first time, has a very worthwhile piece up at Aeon Magazine, The id and the eco: In dealing with climate change, we are in the terrain that psychoanalysis calls resistance or defence — the ability to defend ourselves from too much mental and emotional pain. Although each statement carries an element of truth, its primary purpose is protective: a rationalisation for inaction. These are subtler forms of denial than those found among outright climate sceptics or deniers. The reality of climate change is acknowledged but its significance is discounted, and the person involved avoids taking any responsibility for the issue. If, however, you delve behind these kinds of statements, you frequently find anxiety, unease and apprehension. Sometimes you find guilt, sometimes grief, and sometimes a sense of impossible conflict…”
Climate Change And Wildfires: What’s The Connection? Here’s a portion of a post at the EPA: “…To determine an amount of wildfire activity in a given year, scientists measure the area burned. The National Interagency Fire Center (NIFC) reports that in 2012 alone, 67,774 wildland fires burned through more than nine million acres of U.S. land, three times more than the five-year averages from a few decades ago. Wildfires are unpredictable and containing them can be challenging and dangerous. According to the NIFC, last year the total direct costs of fire suppression exceeded 1.9 billion dollars nationwide. But that’s not all: wildfires are a major source of airborne pollutants such as fine particulate matter that can lead to serious health issues. In a study funded by EPA, scientists are modeling projections of wildfire activity fifty years from now. The study takes into account the possible effects of global warming—changing vegetation and less precipitation—in areas already prone to wildfire activity, to determine how future fires may affect air quality…”
FERC Chair: Solar “Is Going To Overtake Everything”. Here’s the intro to an optimistic outlook from Greentech Media: “If anybody doubts that federal energy regulators are aware of rapidly changing electricity landscape, they should talk to Jon Wellinghoff, chairman of the Federal Energy Regulatory Commission (FERC). “Solar is growing so fast it is going to overtake everything,” Wellinghoff told GTM last week in a sideline conversation at the National Clean Energy Summit in Las Vegas. If a single drop of water on the pitcher’s mound at Dodger Stadium is doubled every minute, Wellinghoff said, a person chained to the highest seat would be in danger of drowning in an hour. “That’s what is happening in solar. It could double every two years,” he said…” (File photo: Wikipedia).
Editor: Awaiting A Climate Change Tipping Point. Here’s the intro to an Op-Ed at The Concord Monitor: “One of these days, the tipping point will be reached. No, not the tipping point that leads to a continued warming of the globe. That one, unfortunately, is probably behind us. The even more elusive tipping point is the action, event or increased collective concern that finally prompts Americans to make combatting climate change a national goal akin to winning a world war. Hurricane Katrina didn’t do it, and neither have Hurricanes Sandy and Irene. So the notion that a slim book and a barnstorming state senator from Iowa will spur the nation to action seems far-fetched. But Sen. Rob Hogg’s book, America’s Climate Century, and his talks across the state this week should move the needle in the right direction. Hogg, who met with Monitor editors yesterday, makes the convincing case that for the next half-century or more “every aspect of our lives will be affected by human-caused global warming and its resulting climate changes, and by the actions necessary to stop climate change before it devastates the world...”
How Extreme Will Future Heatwaves Be? Choose Your Own Adventure. The Guardian has the story – here’s an excerpt: “…Coumou & Robinson looked at the frequency of rare and extreme (3-sigma, meaning 3 standard deviations hotter than the average) and very rare and extreme (5-sigma) temperature events. 3-sigma represents a 1-in-370 event, and 5-sigma is a 1-in-1.7 million event. As shown in the video below from NASA, summer temperatures have already begun to shift significantly towards more frequent hot extremes over the past 50 years. What used to be a rare 3-sigma event has already become more commonplace…”

Welcome to the WeatherNation blog. Every day I sift through hundreds of stories, maps, graphics and meteorological web sites, trying to capture some of the most interesting weather nuggets, the stories behind the forecast. I’ll link to stories and share some of the web sites I use. I’m still passionate about the weather, have been ever since Tropical Storm Agnes flooded my home in Lancaster, PA in 1972. I’ve started 5 weather-related companies. “EarthWatch” created the world’s first 3-D weather graphics for TV stations – Steven Spielberg used our software in “Jurassic Park” and “Twister”. My last company, “Digital Cyclone”, personalized weather for cell phones. “My-Cast” was launched in 2001 and is still going strong on iPhone, Android and Blackberry. I sold DCI to Garmin in 2007 so I could focus on my latest venture: WeatherNation. I also write a daily weather column for The Star Tribune startribune.
