Many residents of Revere, Massachusetts, about 5 miles northeast of Faneuil Hall in downtown Boston, were shocked that an EF-2 tornado could strike at 9:30 AM on a Monday morning. It was on the ground for 2 miles, ripping up 100 homes and businesses - a blunt reminder that tornadoes can hit cities and close-in suburbs.
A little concrete & asphalt doesn't protect you from nature's most fickle wind. The urban heat island and drier air over metropolitan areas may inhibit small tornadoes, but large twisters pull in moisture & energy from a 5-10 mile radius. A few high-rise buildings won't stop them from forming. A tornado is more of a process than an object. If you see large hail or rotation, even in the morning in a major city, start looking for an underground shelter.
July has been the deadliest month for U.S. tornadoes since 1978.
The next unusually strong southward bulge in the jet stream may treat us to 60s and 70s by the end of next week. Another premature puff of autumn.
Enjoy 80s into Sunday; the best chance of T-storms late Friday, again Monday. No sizzling heat or controversial dew points.
It's been an amazing week. And no, I take nothing for granted these days.

July Spills Into The Weekend - Hints of Late September Next Week? Long-range guidance shows mid-80s over the weekend with dew points near 60F, sticky but not too oppressive. A few T-storms may sprout late Sunday, an approaching storm spreading heavier, steadier, almost autumnal rains into the state Tuesday into Thursday as temperatures fall thru the 70s into the 60s. Yeah, it's too early for this.
Flash Flood Potential. 60-hour accumulated rainfall predictions show some 3-6" amounts from near Denver to Oklahoma City and Tulsa, where Flash Flood Watches are already posted. Scattered instability T-showers pop up from Wisconsin into much of New England and the Carolinas into Friday morning. 4 KM WRF accumulated rain forecast courtesy of NOAA and HAMweather.
100 Homes Damaged As Tornado Jolts Revere. The photo above looks like something you might see in Kansas or Oklahoma. But it was from Revere, a close-in suburb of Boston, within 5-6 miles of Fanuil Hall, hit by an EF-2 tornado Monday morning. The Boston Globe has a remarkable look at the damage, including photos and videos; here's a link: "A tornado carrying winds as high as 120 miles per hour roared through Revere Monday, uprooting hundreds of trees, ripping roofs off houses, and spurring an intensive recovery effort that could last weeks..."

EF-2 Tornado In Revere, Massachusetts: Damage & Debris But No Serious Injuries. Which is miraculous, considering the population density of the suburb impacted by Monday's tornado. Here's an excerpt from Public Safety Reporter: "The National Weather Service in Taunton, MA has confirmed that an EF-2 tornado touched down on the morning of July 28, 2014 in Chelsea and Revere in Suffolk County, MA. The tornado is unusual because of the geographic location that was hit, and the morning time frame that the tornado struck - about 9:32 AM to 9:36 AM EDT. The tornado had a path length of 2 miles and a path width of 3/8 of a mile. Maximum wind gusts were estimated at a range of 100 MPH to 120 MPH..."

USA Having Deadliest July For Tornadoes Since 70s. USA TODAY has some perspective on the sudden rash of tornadic storms in recent weeks; here's an excerpt: "...The ferocious tornado that roared through a campground in Virginia on Thursday morning, killing two people, raised the national death toll for July tornadoes up to six. That's the most tornado deaths in July since 1978, when tornadoes killed 11 people that month, according to meteorologist Harold Brooks of the National Severe Storms Laboratory in Norman, Okla. The worst July for tornadoes was 1893, Brooks said, when 73 people were killed..."

Miles Cary).
Why The Sudden Uptick in Tornadoes? The jet stream is still misbehaving, dipping unusually far south for July; stalled in a hot, dusty and fiery "ridge" formation over the western USA and Canada. Tornado season should be winding down, but the last few days have brought a string of high-profile tornadoes, including the close-in suburbs of Boston - that's the subject of today's Climate Matters: "After a relatively quiet beginning to the season, what happened? Tornadoes along the front range, sure, but Boston? Just 5 miles north of Faneuil Hall?! WeatherNationTV Chief Meteorologist Paul Douglas goes over the data and tries to connect the dots."
Tracking Tornadoes For Your County Since 1950. The Midwestern Regional Climate Center (MRCC) has an impressive online tool that allows you to zoom into your county, or any county in the Midwest, to see all the tornadoes from 1950-2013, filtered by strength (EF-0 to EF-5).
Better Than A Siren: How New Technology Is Keeping People Safe From Tornadoes. Research suggests that if multiple media sources are (simultaneously) sending you the same tornado warning you may be more likely to act on that information - if not only TV and radio is displaying the warning, but you're getting texts, e-mails and alerts. Here's an excerpt from The Los Angeles Times: "...Capabilities exist today so that when a tornado is coming, people can simultaneously receive phone calls at home and work; texts and push notifications from their mobile phones/tablets; pop-up alerts on their laptops/desktops; messages via LED billboards and signs alongside roads and highways; and automated announcements via loudspeaker and intercoms at schools, athletic events, and malls. Everything, all at the exact same time..."

Annoying Minor Floods Are Increasing on U.S. Coasts. AP reports on the implication of astronomical forcing (tides) and storm surges from Nor'easters and tropical systems - coupled with slowly rising sea levels. Here's an excerpt of an AP story: "Along much of America's coasts, the type of flooding that is more annoying than dangerous has jumped more than fivefold in the last 50 years, the federal government reported Monday. Scientists blame rising seas, saying this is one of the ways global warming is changing everyday lives. The National Oceanic and Atmospheric Administration studied coastal trends in what it calls nuisance flooding, where no one is hurt but people have to deal with flooded roads and buildings..."

All Wet: USA's Top 10 Cities for "Nuisance" Flooding. USA TODAY has more details on the recent report; here's a clip: "...Sea level has risen nearly 8 inches worldwide since 1880, but it doesn't rise evenly. In the past 100 years, it has climbed about a foot or more in some U.S. cities. Depending on fossil-fuel emissions, scientists project global sea level will rise about one foot to slightly more than 3 feet (or 39 inches) by 2100, according to last year's Fifth Assessment Report by the United Nations' Intergovernmental Panel on Climate Change. Here are the 10 U.S. cities with the greatest percentage increases in "nuisance" flooding since the 1960s.
City / Percentage increase
Annapolis, Md. 925%
Atlantic City, 682%..."

Looking Back at Hurricane Andrew, Over 20 Years Later. KBTX.com takes a look back at a small but fierce Category 5 storm that struck just south of Miami in August, 1992; here's a clip: "Hurricane Andrew made landfall in South Florida in August of 1992. The community of Homestead, south of Miami, was one of the locations hardest hit by the Category 5 storm. According to the Miami - South Florida National Weather Service office, Hurricane Andrew caused an estimated $26 billion in damages -- making it the most expensive natural disaster in United States history, at that time. Andrew came on land on August 24th, with a sustained wind of 175mph. The storm caused 65 deaths, destroyed over 23,000 homes, and is estimated to have damaged an additional 108,000 more between South Florida and South Central Louisiana, where it made a second landfall after moving back into the Gulf of Mexico..."
El Nino Indicators Ease. Here's an excerpt of an update from the Australian Bureau of Meteorology: "Despite the tropical Pacific Ocean being primed for an El Niño during much of the first half of 2014, the atmosphere above has largely failed to respond, and hence the ocean and atmosphere have not reinforced each other. As a result, some cooling has now taken place in the central and eastern tropical Pacific Ocean, with most of the key NINO regions returning to neutral values. While the chance of an El Niño in 2014 has clearly eased, warmer-than-average waters persist in parts of the tropical Pacific, and the (slight) majority of climate models suggest El Niño remains likely for spring. Hence the establishment of El Niño before year's end cannot be ruled out. If an El Niño were to occur, it is increasingly unlikely to be a strong event..."
Weather Satellites Criticized Again, This Time For Security Risks. Could our weather satellites be hacked? The idea may not be as far-fetched as it sounds. Here's an excerpt from eenews.net: "...The data from weather satellites could be hacked because of "significant security deficiencies" in the information systems at the National Oceanic and Atmospheric Administration, according to a new internal report. The inspector general of the Commerce Department -- which houses NOAA -- released the report after Greenwire requested it through the Freedom of Information Act. It raises multiple concerns about the security of the systems that collect and disseminate weather data, raising the risk of cyberattacks..." (Image: NASA).
What Makes A Major Disaster? TheHill has an interesting Op-Ed; here's a clip: "What constitutes a major disaster? The Senate Subcommittee on Emergency Management, Intergovernmental Affairs, and the District of Columbia takes up this question this week, and the answer significantly affects our nation’s response to disasters. The Federal Emergency Management Agency (FEMA) currently responds to too many disasters, contributing to rising disaster loses. Congress should significantly raise the threshold for federal disaster declarations to ensure the sufficiency of federal assistance when truly needed..."
Fukushima Study: Think About Unthinkable Disasters. From TMI to Fukushima to Hurricane Katrina in 2005 it's usually a cascade of unintented consequences, a domino effect of events that nobody could anticipate or model in advance, that magnify the impacts of a disaster in unimaginable and unpredictable ways. Here's an excerpt of a story from AP and NBC40.net in South Jersey: " A U.S. science advisory report says Japan's Fukushima nuclear accident offers a key lesson to the nation's nuclear industry: Focus more on the highly unlikely but worst case scenarios. That means thinking about earthquakes, floods, tsunamis, solar storms, multiple failures and situations that seem freakishly unusual, according to Thursday's National Academy of Sciences report. Those kinds of things triggered the world's three major nuclear accidents. "We need to do a soul searching when it comes to the assumptions" of how to deal with worst case events, said University of Southern California engineering professor Najmedin Meshkati, the panel's technical adviser. Engineers should "think about something that could happen once every, perhaps 1,000 years" but that's not really part of their training or nature, he said..."
File photo above: "In this March 12, 2011 photo provided by GeoEye, Fukushima, Japan is shown. Japan's nuclear crisis intensified Sunday as authorities raced to combat the threat of multiple reactor meltdowns and more than 180,000 people evacuated the quake- and tsunami-savaged northeastern coast where fears spread over possible radioactive contamination."
Ebola's Spread. It's a wonder any of us want to check news headlines after hearing about this one; The Economist has more on the disease and it's rapid spread, already the worst on record. Here's a clip: "..Ebola has no vaccine or cure, and kills up to 90% of those infected. It is transmitted to people by wild animals or by other infected patients. Fruit bats, often eaten by people living in West Africa, are thought to be a host for the virus, which starts with flu-like symptoms but can impair kidney and liver function, and in severe cases damages blood cells, leading to external and internal bleeding..."
Get Ready for Generation Z. Younger Americans tend to be more optimistic, altruistic and entreprenurial; here's an excerpt from Maclean's: "...The influential author and consultant Don Tapscott is a Gen Z optimist. His 2008 book, Grown Up Digital, features a study of 11,000 kids who were asked whether they’d rather be smarter or better looking: 69 per cent chose “smarter.” So is social researcher Mark McCrindle, of Sydney-based McCrindle Research, who has been looking at Gen Z for seven years. “They are the most connected, educated and sophisticated generation in history,” he says. “They don’t just represent the future, they are creating it...”
Girl's Galaxy S4 Smartphone Burns Under Her Pillow As She Sleeps. But was there a fire extinguisher app installed? Good grief. Yahoo Tech has the story; here's a clip: "...Last week, a 13-year-old North Texas girl plugged her Samsung Galaxy S4 in for its nightly juice-up before hitting the sack, only to be awoken by the smell of something burning hours later. When she got up and searched around for the source of the stench, she realized that she had wedged her charging phone under her pillow. And not only was the backside of the pillow scorched, but the phone was fried into an unrecognizable slab of plastic and melted components..." (Image above courtesy of Fox 4 in Tampa).
Part Car, Part Motorcycle, Polaris Slingshot Is The Inverted Trike Every Kid Dreams Of. I couldn't agree more. Here's an excerpt of a story at Gizmag: "...The noted Minnesota-based maker of all-terrain vehicles and snowmobiles officially unveiled the new three-wheeled roadster this week in the United States and Canada. Because of its open cockpit, this two-seater reversed trike is officially classified as a motorcycle rather than a car, meaning you'll need a helmet and a motorcycle endorsement on your license to drive one. The unique combination of car and motorbike offers a driving experience that's also different from both, thanks to its broad stance, sport-tuned suspension and a chassis that rides just five inches above the road..."

General Mills Takes New Steps To Combat Climate Change. Here's a clip from a story at The Los Angeles Times: "General Mills said Monday it would take new steps to combat climate change, including expanding its emission reduction targets to include its vast network of suppliers and contractors. About two-thirds of General Mills’ greenhouse gas emissions and 99% of its water use comes from its indirect operations such as the farms it purchases raw materials from. The Minneapolis-based company known for brands such as Cheerios, Pillsbury and Haagen-Dazs pledged to include their supply chain in its emission reporting and greenhouse gas reduction targets..."

That expands on the company's existing pledge not to purchase palm oil from deforested land." (Rick Bowmer / Associated Press).
Global Warming May Increase With Rising Water Vapor In The Atmosphere. Scientists are observing an increase in water vapor 3-7 miles above the ground, but what's triggering this moistening trend aloft? Here's an excerpt from a story at Science World Report: "...The researchers measured water vapor in the upper troposphere collected by NOAA satellites. Then, they compared this data to climate model predictions of water circulation between the ocean and the troposphere in order to see whether the changes in water vapor could be explained by natural or human-induced causes. So what did they find? It turns out that the rising water vapor can't be explained by natural forces. Instead, it's probably due to increased greenhouse gases..."

The Centerpiece of Obama's Energy Policy Will Actually Make Climate Change Worse. Will natural gas, which has roughly half the greenhouse emissions as coal, save us from ourselves? Naomi Oreskes has the Op-Ed at The Nation; here's the introduction: "Albert Einstein is rumored to have said that one cannot solve a problem with the same thinking that led to it. Yet this is precisely what we are now trying to do with climate change policy. The Obama administration, the Environmental Protection Agency, many environmental groups and the oil and gas industry all tell us that the way to solve the problem created by fossil fuels is with more fossils fuels. We can do this, they claim, by using more natural gas, which is touted as a “clean” fuel—even a “green” fuel...."

NBC Shows How To Report on the Economic Costs of Climate Change. Media Matters has the recap; here's an excerpt: "...The July 29 edition of NBC's The Today Show reported on the extreme costs of fighting the dozens of wildfires currently burning in Yosemite National Park and across California, and how they are connected to climate change. The fires, taking place during Yosemite's driest year on record, have destroyed 20 homes and forced over 1,200 people to be evacuated. NBC correspondent Miguel Almaguer stated that the dozens of California wildfires are "costing big money," expanding that the state of California will spend $1 billion to fight wildfires this year. Almaguer also highlighted how global warming has had a direct impact on the fire, citing firefighters who are working on "the front lines of climate change"...
World's Religions United For New York Climate Summit. The climate summit will be hosted by UN Secretary General Ban Ki-moon on September 21. Here's an excerpt from RTCC: "...Faith leaders of all religion are important voices for people all around the world. No matter what faith, whether Muslims, Christians, Hindus, they have a care for the creation. Gathering such leaders is an important space for creating a voice for this faith movement," said Mattias Soderberg from ACT Alliance, one of the groups sponsoring the event..."
