Ripening Colors. My semi-educated hunch: this upcoming weekend may be the best time to head out in search of peaking color. According to the Minnesota DNR 75-100% of the leaves have riped up just north and west of the Twin Cities, and along Lake Superior's North Shore. Up north colors may be past-peak by the second week of October. That, and there's a good chance of rain the weekend of October 8-9.
Change In The Pattern? 500 mb winds next Thursday show a strong trough of low pressure over the Northern Rockies, a broad south/southwest flow pumping warm (moist) air into the Plains and Great Lakes The chance of rain increases the end of next week, with cooler weather returning by the second weekend of October. Significantly cooler weather is likely by mid October for the northern tier states - make the most of next week's 70s.
Milwaukee Waterspouts On September 24. The local Milwaukee NWS has more on the remarkable outbreak of waterspouts last weekend on Lake Michigan: "A somewhat rare and fascinating weather pattern took shape over Lake Michigan on September 24, 2011. Two important ingredients came together during the late morning and afternoon to produce a rare "outbreak" of waterspouts stretching from off shore of Milwaukee, south to the Chicagoland area. The environmental ingredients responsible for this setup were simple; a seasonably cold airmass moving over Lake Michigan, at a time when the Lake Michigan water temperatures were still hovering in the lower to mid 60s. This created a temperature difference of nearly 14 degrees Celsius, or about 25 degrees Fahrenheit, between the air at the water surface and the air at around 4000 feet (we call this the Delta-T.) Amazingly, the showers and isolated thunderstorms that developed eventually had cloud tops that reached nearly 26000ft. This was due to the added heat from the warm lake temperatures."
Flash Flood. Here's a YouTube clip showing the result of flash flooding near Gettysburg, Pennsylvania - reports of 2-3" rains in less than 2 hours - falling on saturated, waterlogged ground.
Freak Hailstorm. This YouTube clip captures some of the craziness during a sudden hailstorm in Windsor, Virginia - reports of tennis ball size hail nearby.
Listen To The Train Whistle. This is some of the most incredible YouTube video I've ever seen - you hear the train coming, the whistle is blaring, and then a wall of water comes toward the camera. This was taken in Belgium, during the aftermath of flooding.
The Future Of The Book. Here's an interesting essay at samharris.org: "Where publishing is concerned, the Internet is both midwife and executioner. It has never been easier to reach large numbers of readers, but these readers have never felt more entitled to be informed and entertained for free. I have been very slow to appreciate these developments, and yet it is clear even to me that there are reasons to fear for the life of the printed book. Needless to say, many of the changes occurring in publishing are changes that neither publishers nor authors want. The market for books is continually shifting beneath our feet, and nobody knows what the business of publishing will look like a decade from now....Journalism was the first casualty of this transformation. How can newspapers and magazines continue to make a profit? Online ads don’t generate enough revenue and paywalls are intolerable; thus, the business of journalism is in shambles. Even though I sympathize with the plight of publishers—and share it by association as a writer—as a reader, I am without pity. If your content is behind a paywall, I will get my news elsewhere. I subscribe to the print edition of The New Yorker, but when I want to read one of its articles online, I find it galling to have to login and wrestle with its proprietary e-reader. The result is that I read and reference New Yorker articles far less frequently than I otherwise would. I’ve been a subscriber for 25 years, but The New Yorker is about to lose me. What can they do? I don’t know. The truth is, I now expect their content to be free."
"Clear Proof" That Climate Change Causes Extreme Weather. Proving cause and effect with weather is tricky - but is there enough evidence to connect a warmer (wetter) atmosphere with an increase in extreme weather events? The story from the U.K. Guardian: "Al Gore has warned that there is now clear proof that climate change is directly responsible for the extreme and devastating floods, storms and droughts that displaced millions of people this year. Speaking to an audience of business leaders, political leaders including Scotland's first minister Alex Salmond and green energy entrepreneurs in Edinburgh, Gore said the world was at a "fork in the road". The former US vice-president and climate campaigner also argued that America has suffered a "breakdown in democratic governance", because members of Congress are obsessed with appeasing special interests in return for campaign funding, rather than confronting climate change. The former vice president and climate campaigner said that US democracy had been undermined. "In the language of computer culture, our democracy has been hacked," he said. In a near hour-long speech to the Scottish low-carbon investment conference, Gore said the evidence from the floods in Pakistan, China, South Korea and Columbia was so compelling that the case for urgent action by world leaders to combat carbon emissions was now overwhelming, Gore said."
Look North America. Here's an Op-Ed from the New York Times: "As American lawmakers struggle to fix the economy, they are missing the elephant in the room — or, more aptly, the polar bear. America has a vast pool of untapped resources in its backyard. The North American basin, the Alaskan Arctic, holds an estimated 30 billion barrels of oil and more than 220 trillion cubic feet of natural gas, as well as rare earth minerals and massive renewable wind, tidal and geothermal energy. The economic potential is in the trillions of dollars, as with the Siberian and Eurasian Arctic basins. The difference is that other nations, like China and Russia, have responded by building polar icebreakers and ice-strengthened ships, and by investing in resource exploration. The United States has not. The Arctic is the newest emerging region, and yet the United States has no action plan. Both the Bush and Obama administrations have proclaimed it to be in America’s strategic interest, but Washington has done little to convert words to action. The Pentagon, Coast Guard, National Science Foundation, academics and nonprofit organizations have compiled study after study. It’s time for policymakers to act."
