Last Semi-Comfortable Day (back to the 90s this week; tropical start to State Fair)

I flew east this weekend to celebrate my dad's 83rd birthday. He's largely responsible for my deep dive into meteorology. Between a tropical storm (Agnes) and weather merit badge in the Boy Scouts I was curious about weather. Dad knew this - and had a stack of newspaper & magazine clippings ready for me at the breakfast table every morning. Now he's graduated to sending e-mail links to stories on his iPad. His daily clipping service continues (without the morning bowl of Wheaties).
His secret? Two brisk walks a day, salads for lunch and tracking (and lowering) his cholesterol. That, and a warped sense of humor. May I be so lucky.
If you thought summer was winding down you're in for a rude surprise. Comfortable 80s will give way to a streak of 90s from Wednesday into next weekend. ECMWF guidance hints at mid-90s with dew points ranging from 60-70F.
An isolated T-shower may pop over northern Minnesota Monday, another swarm of storms Thursday could pass north of MSP. Portions of Minnesota are drying out again, and although I don't expect a rerun of the 2012 drought a few pockets of moderate drought may return by September.
I'm looking forward to sweating out the State Fair next Saturday - spending most of my time at the deodorant-on-a-stick booth.
Shift In The Pattern. The (amazingly) persistent kink in the jet stream that has funneled a parade of Canadian cool fronts south of the border, sparking frost over the Minnesota Arrowhead and 30s over interior New England in recent days will become more progressive, blowing west to east, allowing a heat bubble to expand eastward into the Plains and Midwest by midweek.

One Hot Week. ECMWF data (above, courtesy of WeatherSpark) shows highs near 90 by Tuesday, then well into the 90s Wednesday, again late in the week. Today will be the last day of comfortable dew points (rising thru the 50s). Bu Thursday the dew point may exceed 70, fueling a few T-storms - especially north of the Twin Cities. Humidity levels drop off a bit late in the week, but 90s may spill over into next weekend.
Summer Swoon. We're not done with the Dog Days, not even close. The map above shows predicted temperature anomalies from Thursday into Monday of next week; readings as much as 10-20 F. above average over northern Minnesota and Wisconsin. Graphic: NOAA CPC and Ham Weather.
"Augtober". Folks living in "Hotlanta" have to be scratching their collective heads right about now. Friday's high of 67 F. was only the 16th time the high temperature on a given day has been cooler than 70 F. Talk about a mixed-up weather map. Graphic: WeatherNation TV.
Weather Vs. Climate: Keeping The Big (Global) Picture. With cooler than average temperatures the last 3-4 weeks over the northern tier of the USA it's tempting to dismiss climate change and global warming, but this misses the distinction between weather and climate. A Canadian breeze has been blowing from Minneapolis to Chicago, D.C. and Boston since late July, but stepping back and looking at the larger picture the trends are undeniable. Here is today's edition of Climate Matters: "Last summer, much of the U.S. was baking in sweltering heat. This year, a different story for the Eastern Half of the U.S. The dog days of summer are missing in action. Wait until you see the comparison of 90 degree days this year compared to last year and compared to average. What kind of summer weather do you prefer? Do you like it hot, or are you happy when it's cooler than average?"
Moisture Needed To Ease Drought. We're running about a 1 to 1.5" rainfall deficit across much of Minnesota - we can make up for that with one good frontal passage and T-storm outbreak (which may happen Thursday). The situation is much worse out west, a nearly 10" rainfall deficit for western Nebraska and Wyoming - the drought continues to worsen over the western third of the USA. Map: NOAA and Ham Weather.
Gulf Coast Fizzle. The tropical depression that tracked over Mexico's Yucatan Peninsula can't seem to get it's act together (too much dry air and wind shear) and will probably drift back into mainland Mexico as a weak tropical wave. The risk to south Texas has dropped considerably; NHC says only a 10% risk of tropical storm formation in the next 48 hours.
Why U.S. Power Companies Don't Want You Putting A Solar Panel On Your Roof. Quartz.com (great site) has the story; here's the intro: "The short answer: It will destroy their business model forever. In the US, electrical utilities are in a charged battle—complete with negative political ads—against solar panel distributors over rules that both sides say could put them out of business. Consumers are caught in the middle. A relatively new swathe of companies like Verengo, Sunrun, Sungevity and SolarCity have spent millions leasing solar equipment to homeowners and businesses. The cost of the lease is offset by savings on their electrical bill. Those savings come not just because of free power from the sun, but also through tax credits—and, most importantly today, because states allow those who have solar panels to sell any excess power back to the grid. The more than 200,000 “distributed solar generators” in the US produce less than 1% of the country’s electricity. But that’s growing thanks to the falling cost of photovoltaics and financing from investors like Google. And this worries the big power companies, particularly country’s two largest, Pacific Gas & Electric and Southern California Edison..."
10 Places You're Not Allowed To See On Google Maps. I found this vaguely interesting, courtesy of mashable.com: "Want an up close view of the Eiffel Tower but can't make it to Paris anytime soon? Google Maps is optimal for virtual sightseeing. But not every landmark is visible on the site — some images are blurred and distorted by countries for security reasons. This means that if you want to see towns or streets in North Korea, you can't. Also blurred is the Royal Palace in the Netherlands and even a power plant on Cornell University's campus in Ithaca, New York. "The satellite and aerial imagery in Google Earth and Google Maps is sourced from a wide range of both commercial and public sources," Google spokesperson Deanna Yick tells Mashable. "These third-party providers are required to follow the law of the countries in which they operate, so some of them may blur images and then supply us with those images..."

How Your Birth Order Can Influence Who You Are. Here's an excerpt of a fascinating story at io9.com: "As many parents can attest, siblings tend to be more different than alike. Some of this may be the result of our birth order, and how we’re subsequently raised. What’s more, birth order may influence our health and sexuality too. Here’s what you need to know about how your birth rank affects your life. Birth order is an incredibly difficult area to study, and as such, is considered highly controversial. There are so many factors to consider outside of a person’s familial rank by age, including the spacing in years between children, the total number of children in a family, socioeconomic status, the sex of siblings, and environmental circumstances during upbringing. It’s not easy to isolate traits that are dependent on birth order..."
Where To Find Free Wi-Fi At U.S. And International Airports. Here's some useful information for business and leisure travelers courtesy of Mashable: "For frequent fliers, nothing is more blissful than an airport with free Wi-Fi. But not every stopover location is so generous. Airfarewatchdog assembled two handy charts that detail everything you need to know about wireless connections at major airports in the United States and worldwide, from airports with free Wi-Fi to those with the most expensive Wi-Fi and usage limitations..."

Climate Change: Forecast For 2100 Is Floods And Heat, And It's Man's Fault. Here's a clip from a story at The Telegraph: "The UN Intergovernmental Panel on Climate Change also said there was a 95 per cent likelihood that global warming is caused by human activities. That was the highest assessment so far from the IPCC, which put the figure at 90 per cent in a previous report in 2007, 66 per cent in 2001, and just over 50 per cent in 1995. Reto Knutti, a professor at the Swiss Federal Institute of Technology in Zurich, said: “We have got quite a bit more certain that climate change is largely man-made. We’re less certain than many would hope about the local impacts.” The IPCC report, the first of three in 2013 and 2014, will face intense scrutiny particularly after errors in the 2007 study, which wrongly predicted that all Himalayan glaciers could melt by 2035..."

Expert: Climate Change Demands Behavioral Change. Here's an excerpt from a story at The Baptist Standard: "...Christians, in particular, should recognize climate change most directly affects people who are least able to adapt, said Hayhoe, founder and chief executive officer of ATMOS Research. “We are told (in the Bible) to love our neighbors as ourselves,” she said, adding love demands each Christian act as a good steward of creation. When she examines research on climate change, Hayhoe explained, she likes to think of the data as God’s voice to his people.
Earth has 'low-grade fever'
“God’s creation is telling us it’s running a fever—a low-grade fever,” she said. People traditionally view weather patterns like a driver whose eyes are fixed on the rearview mirror, without considering changing conditions, she said. The climatological history of the High Plains demonstrates cyclical change between hot and cold, wet and dry..."

As Northeast Asia Bakes, Climate Scientists Predict More Extreme Heat Waves On The Horizon. We're seeing more of these sudden (and prolonged) heat spikes, 2 to 4 standard deviation extremes, as explained by Time Magazine; here's a clip: "Northeast Asia is on fire. Yesterday temperatures in Shanghai hit an all-time high of 105.4ºF (40.8ºC), the hottest day in the coastal megacity since Chinese officials began keeping records some 140 years ago — during the Qing dynasty. On Aug. 12 the heat reached 105.8ºF (41ºC) in the southern Japanese city of Shimanto, the hottest temperature ever recorded in the country. Hundreds of people throughout South Korea have been hospitalized because of heatstroke, even as the government was forced to cut off air-conditioning in public buildings because of fears of a power shortage. As heat waves go, it’s a tsunami, similar to the brutally hot weather that singed Europe 10 years ago, which contributed to the deaths of over 30,000 people. It’s also a glimpse of a blazingly hot future..."

Climate Change Is Scary, But I'm Not Scared. No, the situation is far from hopeless, as the author of this Op-Ed at Living Green Magazine points out - here's an excerpt: "...So, why am I not scared? Why did I decide to have a baby in the face of this knowledge? Because there are hopeful trends. Technology can be implemented very quickly, and views can change equally quickly. The impossible can quickly become inevitable. A recent poll showed that young people think that climate change deniers are “ignorant” “out of touch” and “crazy”. They also don’t care much for cars, and prefer modes of transportation that allow them to text at the same time. They think electric cars and solar panels are cool. And it’s not just our kids’ attitudes that give me hope. The technological solutions are here. The price of solar panels has come down 80% since 2008. Imagine if a shirt at the Gap was marked as 75% off—a few more shirts would sell, and indeed, as you’d expect, solar panels are flying off the racks..."
Climate Policy's Twin Challenges. Here's a portion of a story posted at The Los Angeles Times: "Climate change presents two distinct problems. The first is linear: A little more warming causes a little more damage. The second is nonlinear: A little more warming pushes some part of the climate system past a tipping point and the damage becomes catastrophic. We need smart climate policies that address both problems, so we can slow incremental damage while also taking out an insurance policy against the growing risk of catastrophic damage. The Arctic is a prime example of a potential tipping point. It is already warming at twice the global rate, with Arctic sea ice disappearing faster than previously predicted. Some scientists calculate that it could disappear for all practical purposes later this decade..."
Solar Panels Return To White House. The Hill has an update; here's the introduction: "The White House is making good on a late 2010 pledge to put up solar panels. “The White House has begun installing American-made solar panels on the first family’s residence as a part of an energy retrofit that will improve the overall energy efficiency of the building,” a White House official said. The installation drew cheers from an environmental group that in 2010 called for panels to return to the White House after the Reagan administration removed a Carter-era solar panel installation..."

Would Things Be Different If The Public Had Perfect Information On Climate Science And Solutions? Here's a portion of a Joe Romm post at Think Progress: "Last week, I wrote about the important Dunlap-McRight paper that found organized climate change denial “Played a Crucial Role in Blocking Domestic Legislation.” Although this is a pretty obvious conclusion to objective observers, the false-equivalence bunch, led by blogger Andy Revkin, couldn’t bring themselves to report on it without giving the professional disinformers equal time. John Rennie, the former editor in chief of Scientific American, slammed Revkin’s piece in a must-read post, “Revkin’s False Equivalence on Climate Message Machines.” Rennie was particularly critical of Revkin’s equating the climate denial machine with a laughable “climate alarmism machine” (whipped up by an Australian disinformer), which equates those who spread outright anti-scientific disinformation (often funded by fossil-fuel interests) with the serious work of climate scientists and governments (and others) who make use of that genuine, scientific work..."
Brave New World: Americans Are Learning To Live With Climate Change. Because when you get right down to it - we won't have much choice. The forecast calls for adaptation. Here's an excerpt from Grist: "The Great American Road Trip — it’s a rite of passage, a national pastime, and increasingly, a tool for spreading the word about looming climate catastrophe. Each summer, a motley parade of veggie buses, vintage motorcycles, and bicycles circulates around the country, its participants out to preach the gospel of green living, and perhaps learn a thing or two in the process. Two of these eco-minded road trippers, Kirsten Howard and Allie Goldstein, recently dropped by the Grist offices in Seattle to tell us about their adventures aboard a 2000 Toyota Sienna minivan. The duo, who recently graduated from the University of Michigan’s School of Natural Resources and Environment, called their adventure the Great American Adaptation Road Trip..."
How "Skeptics" View Arctic Sea Ice Decline. Here's an excerpt from Skeptical Science: "September Arctic sea ice extent data since 1980 from the National Snow and Ice Data Center (blue diamonds). "Recovery" years, meaning years when the sea ice extent is greater than the previous year, are highlighted in red to mock the repeated cynical claims of climate change "skeptics" that global warming has somehow stopped. Many factors affect the annual summer decrease in Arctic sea ice extent, and it is illogical at best to claim any "trend" by cherry-picking only brief periods of data. The obvious true long-term trend in Arctic sea ice extent (red second-order polynomial curve fit) is that it is declining at an accelerating rate..."
2012 State Of The Climate: Glaciers. Here's the introduction to a story at NOAA's Climate.gov focused on glacier retreat around the world: "Around the globe, some 370 million people live in basins where rivers derive at least 10 percent of their seasonal discharge from glacier melt. Glacier melt provides drinking water for human populations, and irrigation water for crops. The damming of glacial melt water even generates hydroelectric power. The retreat of the majority of mountain glaciers worldwide is one of the clearest signs of long-term climate change....Between 1980 and 2011, glaciers around the world lost the water equivalent of 15.7 meters. That would be like slicing a roughly 17-meter-thick slab off the top of the average glacier and repeating that exercise worldwide."
