October 29 in Minnesota Weather History. Source: MPX National Weather Service:
1951: A early snow storm dropped as much as 8 inches of snowfall in north central Minnesota. Mora had 8 inches, while Long Prairie received 6 inches. Glenwood, Little Falls, Morris, and New London all had 5 inches of new snow. Meanwhile, surrounding areas received a couple of inches.
1936: Gale dust storm causes damage in Central Minnesota. Heavy wind damage is reported in Stearns County.
Why can’t we put more people to work on badly-needed infrastructure upgrades, with increasing climate volatility and weather extremes in mind? The American Society of Civil Engineers gave the USA’s infrastructure a D+ in a 2013 report card.
Meanwhile a recent study in Proceedings of the Institution of Civil Engineers says that from 1980 to 2007 90 percent of all global disasters were triggered by flooding; either by heavy rain, hurricane, tsunami or some other natural event.
The frequency of extreme flooding is rising, especially Midwest to New England. The rain is falling harder, washing out more roads and bridges in the process. There has to be a smarter way to rebuild America’s aging roads and bridges.
A reinforcing cold front sparks a few sprinkles early. A cold north wind kicks in by tonight and we may not climb out of the 30s tomorrow as winds slowly ease under the center of high pressure. A chilly Halloween but nothing wet or flaky falling from the sky, and winds will be light – no chill factor.
We just get a glancing blow of cold air; the main event sparks lake effect snow showers over the Great Lakes and a big nor’easter, which may remain just offshore.
Plenty of weather drama on either coast, but I still see a mild, dry bias across the central USA into early, possibly mid November. The ECMWF is hinting at 60s, even an outside shot at 70F, one week from Saturday.

Data from the Minnesota DNR shows highs, lows and precipitation on Halloween since 1990. Assuming a high in the upper 30s to near 40F on Friday it will be the coolest Halloween since 2006.
A Vortex of Relative Warmth. Temperature anomalies show unusually mild air over far northern Canada and much of the Arctic region, where temperatures yesterday were nearly 3.5F warmer than average. We will see cold and snow in the coming months (no kidding Paul!) but Old Man Winter doesn’t appear to be in any great hurry this year.

Not So Fast Polar Vortex! Why This Winter Might Not Be So Brutal After All. Note to self: don’t bet the farm based on a 5 month forecast. Here’s an excerpt from a story at Salon that does a good job summing up what we know, and what we are pretending to know about the winter to come: “…Sobel says that despite the headlines, it’s doubtful we will be seeing a winter as cold as last winter was in the eastern U.S. “Last winter was very extreme by historical standards, so it is improbable in any year,” says Sobel. “No information currently available (including the state of El Niño), or that will be available ahead of time, is strong enough to change that. It’s not impossible that this winter will be as cold or colder than last, it’s just very unlikely.”
Superstorm Sandy Anniversary: Remembering Hurricane Sandy 2 Years Later. Here’s an excerpt of a good summary of Sandy from weather.com: “…As the animation above shows, before Sandy even made landfall, tropical storm force winds extended outward in diameter some 943 miles from southwest to northeast, the biggest circulation of any tropical system on record. The sheer size of the storm played an important role in the devastation Sandy dealt to the East Coast. Among the many factor that influence storm surge, size matters, because as the National Hurricane Center notes, bigger storms impact a greater area of the ocean over a longer period of time than smaller storms, thereby enabling a large storm to push more ocean water ashore…”
Hurricane Sandy’s Lesson: Resilience Isn’t Enough. Here’s a clip from a post at the Harvard Business Review that caught my eye: “…Building resilience and adaptability are necessary actions and great to see. But there is more than a hint of a defensive posture here – we’re being reactive. Adaptation is critical, but as a sole strategy, it’s kind of silly and potentially devastating. We can build some walls around lower Manhattan but where will the water go? I don’t think New Jersey will appreciate the extra dose of storm surge. And how high a wall can we even build? If we continue with business as usual and think we’ll just adapt, we will be sorely disappointed…” (File photo: AP).
Hoboken Oceanographer Dreams of Slowing Hurricanes Before Landfall. There are some practical considerations here, including what 30-50 foot seas might do the pumps required, but under the headline of vetting all ideas, here’s an interesting one – an excerpt courtesy of NBC New York: “…His plan is to slow down a hurricane by deploying hundreds of thousands of floating tubular pumps — directly in the path of an approaching storm. Each pump would be upwards of a thousand feet long, using the kinetic energy of undulating waves to draw cold water from the depths of the ocean all the way to the surface. By cooling the surface water just two degrees, Blumberg estimates a storm could be reduced from a category-3 to a category-1 designation. From a category-5 to a category-3 designation…” (Hurricane Igor file: NASA).
Study Says Upgrading Infrastructure Could Reduce Flood Damage. Phys.org has the article which includes this interesting nugget: “…From 1980 to 2007, about 90 percent of all global disasters were caused by flooding either by rain, tsunami, hurricane or some other natural event. At the same time, the American Society of Civil Engineer’s 2013 Report Card for America’s Infrastructure gave the country a dismal D+. The group said $3.6 trillion was needed by 2020 to address the most serious problems…”

Overall, the researchers revealed a much wider problem.

Cigarette Plant Will Be Turned Into A Factory for Solar and Wind Farm Batteries. Think Progress has the story; here’s an excerpt: “Deep in tobacco country, the once booming Phillip Morris cigarette plant in Concord, North Carolina has been reborn into a facility that churns out batteries for solar and wind farms. Swiss startup battery manufacturer Alevo plans to open up the 3.5 million square-foot plant Tuesday, which will produce utility-sized batteries to store electricity harvested from wind and solar plants, according to Fortune…”

Home Of The Brave? Why is there a question mark at the end of the first stanza of America’s National Anthem? Gizmodo takes a look; here’s an excerpt: “Everybody knows that “The Star-Spangled Banner” boldly proclaims that our flag flies over the land of the free and the home of the brave. But in Francis Scott Key’s original 1814 manuscript for our national anthem, there are surprisingly more question marks than you might guess — including after the phrase “home of the brave?…”
Here’s What It’s Like To Be A Woman Walking Through The Streets of New York. 100 catcalls in 10 hours? The Daily Dot takes a look at a video that’s gone viral: “…A new PSA from Rob Bliss and Hollaback exposes a close look at the catcalling and street harassment many women go through daily. With a GoPro camera strapped to his backpack, he walked in front of Shoshana B. Roberts, who volunteered for the project, as she silently walked around New York City for 10 hours. In the process, she had more than 100 instances of verbal street harassment—not including winks and whistles—from people of all backgrounds…”
Europeans Recall Fireball Whiskey Over A Sweetener Also Used in Antifreeze. The Daily Beast has the details; here’s a clip: “Bottles of Fireball whiskey, the insanely popular cinnamon-flavored frathouse favorite, are being recalled in some European countries—because it’s got too much of a chemical used in antifreeze (among other things) inside. Late last week, the whiskey’s European bottler informed the makers of Fireball that they were out of compliance with European regulations…”

Superstorm Sandy Anniversary: “It’s (Still) Global Warming, Stupid” A higher sea level, more water vapor, warmer sea surface temperatures and a highly unusual tropical track for late October – a warming climate made Sandy worse. Here’s an excerpt from Think Progress: “…So we have nearly doubled the chances for a Sandy-type storm surge with just the modest several-inch sea level rise we have caused to date with carbon pollution. This study points out future Sandy-level storm surges will result from weaker storms than Sandy as sea levels rise. The NOAA study has an “intermediate high scenario” of 2 to 4 feet of sea level rise by 2100 and a “High scenario,” where sea level rises 4 to 7 feet by 2100…”
What Caused The “Pause” in Global Warming? Air temperatures have leveled off; additional heat being pumped into the oceans, according to climate scientist Kevin Trenberth. Here’s an excerpt of his explanation at The Conversation: “…These changes in the atmosphere cause changes in the ocean and have led to heat being stored deeper than 700m in the ocean. while heat has also been carried down deeper in the subtropical Pacific, away from the surface. The largest region of the planet that has not warmed in the 2000s is the eastern half of the Pacific Ocean. The planet is warming, but heat is effectively being dumped deeper in the ocean…”

Climate Depression Is For Real. Just Ask a Scientist. A story in Grist argues that climate scientists are human too, and many of them are trying to cope with the implications of their own research. Here’s a clip: “…Parmesan certainly isn’t the first to experience some sort of climate-change blues. From depression to substance abuse to suicide and post-traumatic stress disorder, growing bodies of research in the relatively new field of psychology of global warming suggest that climate change will take a pretty heavy toll on the human psyche as storms become more destructive and droughts more prolonged. For your everyday environmentalist, the emotional stress suffered by a rapidly changing Earth can result in some pretty substantial anxieties….”
With Storms Intensifying, Milwaukee Braces for Bigger Floods. The Daily Climate takes a look at how a more volatile climate is impacting Milwaukee; here’s a clip: “...Milwaukee is emblematic of how climate change is forcing the hand of sanitation departments in the Midwest. More frequent, intense storms threaten aging systems, making repairs, upgrades and innovative solutions more urgent. Climate change “keeps me up at night,” said Kevin Shafer, executive director of the Milwaukee Metropolitan Sewerage District. “Before, we had a design criteria, and Mother Nature followed a historic trend. Now the historic trend is thrown out of whack.” The Midwest is already seeing more frequent and intense storms, with more precipitation on the way, said Don Wuebbles, a professor of atmospheric science at the University of Illinois and member of the scientific team behind the 2014 U.S. National Climate Assessment. Eight of the 10 wettest years for daily precipitation in the upper Midwest have happened since 1978…”
The Varieties of Denialism. This subject obviously extends well beyond climate science. Here’s the intro to a story by Massimo Pigliucci at Scientia Salon: “I have just come back from a stimulating conference at Clark University about “Manufacturing Denial,” which brought together scholars from wildly divergent disciplines — from genocide studies to political science to philosophy — to explore the idea that “denialism” may be a sufficiently coherent phenomenon underlying the willful disregard of factual evidence by ideologically motivated groups or individuals….”
