53 F. high in the Twin Cities Thursday.
41 F. average high for November 15.
51 F. high on November 15, 2011.
60 F. highs possible next Wednesday, and the Saturday after Thanksgiving.
Thanksgiving Weather: 46-51 F, patchy clouds behind a weak cool frontal passage, probably dry.
A Stubborn Drought. 100% of Minnesota is now classified as “abnormally dry”, over 43% of the state in a severe drought, including most of the Twin Cities metro. Extreme drought covers most of southwestern Minnesota, extending into St. Cloud. The drought signal is pervasive, and will probably spill over into the first half of winter. Details from NOAA’s U.S. Drought Monitor.
Aurora Watch. Thanks to Andrea Clarke in Saskatchewan for passing this along. The Northern Lights have been very visible (and vivid) in recent nights – worth a look tonight, as skies should be clear to partly cloudy.
And Then There Were Four. The local NWS office now counts 4 small (EF-0) tornadoes last Saturday, as a vigorous cold front plowed across the state. Doppler radar doesn’t work nearly as well on small, brief tornadoes that spin up along a squall line – a very different scenario from classic (large) supercell thunderstorms, the isolated cells that spawn big tornadoes well in advance of the cold front during spring and summer. Here’s more from the NWS: ” There were two tornadoes in this region (map) that occurred Saturday night, November 10th. One was near Interstate 494 and Highway 13. The other tornado occurred near Lilydale, between Wachlter and Butler Ave, or paralleling Highway 13. Two areas of straight line wind damage occurred from near Dodd Road and Highway 110, northeast to Robert Street and Sidney Street; and along Highway 13, between Mendota and Lilydale. Both of the tornadoes had a path length of approximately one-half mile.”
Misplaced Priorities. Maybe it’s just me, but the media’s sudden obsession with “the Petreus affair” seems way off-base, considering the carnage, heartache and loss on the east coast in the wake of Sandy. This web site sums up the hypocrisy of leading with lurid tales of sex at high levels, when hundreds of thousands of Americans are trying to put their lives back together again. It’s worth a look.
Not Bad For Late November. The pattern looking out 10 days would look right at home in mid-October. Jet stream steering winds are lifting north into Canada, bottling bitter air many hundreds of miles north of Minnesota until further notice. Temperatures will run 5-15 F. above average thru the last weekend of November; a shot at 60 next Wednesday, again the Saturday after Thanksgiving. A cooler front may knock highs into the 40s next Thursday for turkey (and football) consumption, but a 50-degree high is possible on “Black Friday”. Power shoppers lined up at Best Buy may only need a light jacket this year. Here’s a shocker: no significant rain (or snow) is in sight.
Sandy Shook U.S. Like An Earthquake. How severe was Sandy? Powerful enough to physically shake the ground many hundreds of miles away. Here’s an excerpt of an amazing article and animation at Our Amazing Planet: “Hurricane Sandy pummeled the United States from Florida to Wisconsin, and its fierce winds caused a vast swath of ground to shake, a new earthquake-monitoring animation shows. The visualization shows seismic stations lit up as the storm approached Florida on Oct. 26. The earthquake monitors detected rolling seismic waves caused by Sandy’s fierce winds out at sea. The earthquake-monitoring network always “hears” a continuous hum of background noise generated in the ocean, called microseism, said Alex Hutko, a seismologist at the Incorporated Research Institutions for Seismology (IRIS) in Seattle, and creator of the Hurricane Sandy animation…”
Surging Storms: Can The US Adapt In Time To Avert Coastal Damage. I would hazard a guess that the short answer is an emphatic no. We’re allowing people to build homes in high-risk coastal areas, and rebuild after major storms like Sandy on a consistent basis. Insanity is defined as doing the same thing over and over, expecting different results. Mandatory federal insurance is required for people living close to sea level, and taxpayers indirectly contribute to this ongoing treadmill of rebuilding. It’s the third rail of politics – nobody wants to say it out loud, but too many people are building in areas prone to repeated storm surges from hurricanes and Nor’easters. Private insurance companies won’t touch these policies – and for good reason. Here’s an excerpt of an article at The Christian Science Monitor: “…Indeed, damage from tropical systems such as Sandy are projected to multiply by the end of the century as the population grows and people put more assets in harm’s way. That’s true whether or not global warming, which many researchers say is feeding extreme-weather events, is factored in. Tropical-cyclone damage now runs about $26 billion a year globally, according to a study published in January in the journal Nature Climate Change. By 2100, increases in population and wealth as economies grow could push that number to $56 billion a year, assuming little or no effort to adapt to the hazard...”

We Survived Hurricane Sandy. Now What? Here’s a clip from a first-person account of Sandy at Huffington Post: “I live on the Texas Gulf Coast. I have lived through a lot of hurricanes and tropical storms. Yet last month, I flew into New York City for a hurricane. Why? Following my recent book launch, I had a lot of important media events, including a potentially game-changing TEDx talk, scheduled starting on October 30. This SQ work is my passion and mission. I didn’t want to miss these events because of cancelled flights. So I left on the second-to-last flight out of Houston to Newark, and arrived at my hotel hoping that Sandy would be more hype than horror. As a storm veteran, I brought a flashlight, extra batteries, boxes of granola bars, and other food with me. I verified that the hotel had a backup generator just in case. I confirmed we were not in the Zone A evacuation area. I stocked up on some bottled water, filled the tub, and hunkered down. Over the next few days, the local news crew became my primary companions…”
Lake Effect Snow From Space. The high-resolution (“MODIS”) satellite from NASA boasts resolutions as good as 250 meters. Here’s an excerpt from a recent NOAA post describing favorable conditions for lake effect snow bands: “Snowfall reports from Cooperative Observers, Spotters, and Social Media indicated anywhere from 2-6 inches of snow fell over Northwest Upper Michigan as of the morning of 11/13. In addition, locations east of Munising near Lake Superior received up to 3 inches of snow (seen through the clouds from Pictured Rocks National Lakeshore to Newberry). The widespread area of Lake Effect Snow highlights the areas that are favored by West to Northwest winds, as the snow quickly diminished after passing over the Huron Mountains (produced just a light dusting in Marquette). This was due to the combination of downslope wind off the higher terrain and the snow showers being removed from the influence of Lake Superior. This lack of snow continued to the east of Marquette until the Pictured Rocks National Lakeshore, where the West-Northwest winds allowed a long enough residence time over Lake Superior to produce lake effect snow. To see a listing of snowfall reports from this lake effect snow, click here.”
Thanksgiving Preview. ECMWF model data (courtesy of WSI) shows unusually mild, dry weather across most of the USA next Thursday; slightly cooler air dribbling southward from Fargo to the Twin Cities. The only rain in the extended outlook: Pacific Northwest, from Seattle to Portland. Old Man Winter will continue to pull his punch over the Lower 48 States thru the last weekend of November.
“Indoor Clouds”. Here’s an excerpt of a fascinating post (and experiment) at mashable.com: “Dutch artist Berndnaut Smilde has developed a way to create clouds indoors by carefully regulating the space’s humidity, temperature and light. This intersection of science and art was recently named one of TIME magazine’s “Best Inventions of the Year 2012.” The fluffy white clouds are summoned up temporarily using a fog machine, creating a surreal experience in the middle of a room. Smilde has created his clouds inside different types of locations, ranging from corridors and hallways, to bedrooms and common spaces…”

Paul’s Conservation Minnesota Outlook for the Twin Cities and all of Minnesota:
Has Obama Turned A Corner On Climate Change? The story from The Christian Science Monitor; here’s an excerpt: “…If the message is somehow we’re going to ignore jobs and growth simply to address climate change, I don’t think anybody’s going to go for that,” Obama said. “I won’t go for that.” Obama dismissed the inverse relationship some ascribe to environmentalism and job growth. The president instead endorsed an agenda that both advances economic growth while making “a serious dent in climate change.” In what is likely an allusion to hurricane Sandy, Obama emphasized the importance of long-term, proactive investments in infrastructure as a means of reducing the reconstruction costs incurred by extreme weather events…”

Be Persuasive. Be Brave. Be Arrested (if necessary). Think climate change can’t effect your investment portfolio? Think again. Here’s a clip of a thought-provoking paper and warning at nature.com: “I have yet to meet a climate scientist who does not believe that global warming is a worse problem than they thought a few years ago. The seriousness of this change is not appreciated by politicians and the public. The scientific world carefully measures the speed with which we approach the cliff and will, no doubt, carefully measure our rate of fall. But it is not doing enough to stop it. I am a specialist in investment bubbles, not climate science. But the effects of climate change can only exacerbate the ecological trouble I see reflected in the financial markets — soaring commodity prices and impending shortages…”
America’s Carbon Compromise. Here’s an excerpt of a new paper at Nature: “This week, a reinvigorated Barack Obama returned to the White House knowing that he was poised on the edge of a fiscal cliff. Rather than relishing his victory last week, Obama must immediately set about crafting a compromise on deficit reduction with congressional leaders. The stakes could hardly be higher — for science, for US citizens and, indeed, for the world. In the event of failure, a budgetary time-bomb of tax increases and sweeping budget cuts will detonate on 2 January. As well as resulting in indiscriminate cuts to funds for scientific research and many other areas, it could knock the United States back into recession and deliver yet another blow to an already fragile global economy…” Image: Clean Technica.
Obama Says He Will Elevate National Climate Change “Conversation”. Here’s an excerpt from a story at Climate Science Watch: “A New York Times reporter asked President Obama at his White House news conference today: “What specifically do you plan to do in a second term to tackle the issue of climate change?” The President’s reply included this: “What I’m going to be doing over the next several weeks, next several months, is having a conversation, a wide-ranging conversation with scientists, engineers, and elected officials to find out what can — what more can we do to make a short-term progress in reducing carbons, and then working through an education process that I think is necessary — a discussion, a conversation across the country about what realistically can we do long term to make sure that this is not something we’re passing on to future generations that’s going to be very expensive and very painful to deal with.”
“Time To Do Something About The Weather”. Here’s an excerpt of a timely Op-Ed at Milwaukee’s Journal Sentinel: “There was precious little discussion of climate change during the presidential campaign and most other political races this year. That may strike some as a little surprising, given the weather that’s been plaguing much of the nation over the past couple of years, which has cost billions of dollars of damage and taken hundreds of lives. Maybe politicians think that climate change has become the new third rail of politics (it used to be Social Security, but these days everyone’s talking about Social Security), but on this issue they’re way behind everyone else. They need to catch up and start making some real proposals on how to mitigate both the trend and the effects – and they need to start doing so as soon as new members are seated in Congress and President Barack Obama renews his oath in January. The people are paying attention. According to a national survey released Tuesday, a large majority of Americans (77%) say global warming should be a “very high,” “high” or “medium” priority for the president and Congress…”
