A Touch of November East of the Rockies This Week (will drones soon replace "Hurricane Hunter" aircraft?)


First Flakes

Everyone, it seems, is looking for cues - tip-offs of what the winter to come might hold. Old fashioned, like last winter's 68 inches of snow, or Kansas City-style, like 2011-2012? Check the wooly bear caterpillars, and see if the squirrels are stocking up on extra nuts, but don't go off the date of the first snowflakes to make your winter call.

Last winter we didn't see the first snow at MSP until October 25, but winter lingered into the following May. In 2011 the first flurries didn't float past your window until November 9. An omen of the 22.3 inches of snow later that winter and record warmth in March, 2012? Not necessarily. In 2004 the first flakes at MSP came early: October 17. Only 25.5 inches fell later that winter. The first snow is random; there's no evidence it's a premonition, a reliable indicator or tip-off of the winter to come.

Today will be typical, for November 19. A stray flake gives way to a hard freeze late tonight, stunted temperatures until the end of the week. We have a new definition of a "warm front": 50F, possible Saturday afternoon. A cold rain early next week gives way to 30s and flurries for Halloween.

A visual first on today's weather blog: a friend snow-blowing his dock. Huh?

"I'll Be In As Soon As I Snow-Blow The Dock" Not sure I've ever seen this before - a good friend of mine, Heidi Rusch, sent in this photo of her husband (Tom Rusch) pushing the snowblower onto their dock up on Pelican Lake, near Breezy Point, where 1-2" slush fell yesterday. "Hey, at least we didn't have to rake leaves!" she added. Good point.

Cosmetic Snowfall. It was just enough snow to get people's attention, enough to coat lawns and fields, although most roads were wet up north. NOAA reports .5 to 1" snows near St. Cloud, about 1.2" at Hillman and nearly an inch at Motley.

Days With 1"+ Snows. On average we see a tenth of a day (?) with 1" or more of snow in October. Translation: it's rare to see an inch of snow in the MSP metro in October. On average we see 3 days in November and 4 days in December with at least an inch, a grand total of 16 separate 1"+ snow days during a typical winter season.

Plants About To Freeze Their Buds Off. Here are the projected 7am surface temperatures Tuesday morning. A freeze is defined as several hours in a row below 28F, cold enough to kill off just about all plant life. We should have those conditions early this morning. 12km NAM guidance courtesy of NOAA and Ham Weather.

A Four Day Preview Of Mid-November. Stay with me for a second: last month felt like late August and early September, so it's only fitting that the latter half of October feels like mid-November. Highs flirt with 40F into Thursday with lows dipping into the 20s. We temporarily redefine the meaning of a "warm front" - 50F will feel pretty tolerable Saturday afternoon, with highs well up into the 40s into the first few days of next week. Graphic: Weatherspark.

Halloween Chills. No Indian Summer to save us this time around; highs on Halloween may hold in the 30s, Trick or Treat temperatures close to freezing. No big Halloween Superstorms brewing this time around. Whew...

A Numbing End To October. Weather systems (in general) have been moving slower this year, and the current cold spell is forecast to linger for the better part of 2 weeks, into the first few days of November. I still suspect we'll see an upward blip by the second week of November, but 70s and 80s? History. 8-14 Day Temperature Outlook courtesy of NOAA CPC and Ham Weather.

Blizzard's Financial Toll May Snow Under Cattle Ranchers. The freak blizzard that dropped as much as 55" snow near the Black Hills of South Dakota is having a major impact on cattle farming; The Rapid City Journal has details: "For South Dakota ranch families reeling from the physical and emotional stress of the Oct. 4 blizzard that killed tens of thousands of farm animals, even tougher days may lie ahead when they confront the financial consequences of the storm. On Thursday, State Veterinarian Dustin Oedekoven estimated that between 15,000 and 30,000 cattle in western South Dakota died of exhaustion or suffocation in the unseasonably powerful storm. The blizzard that dumped up to 55 inches of snow in some places hit ranchers just as they were looking forward to the promise of strong markets for their calves, yearlings and bred heifers this fall..."

South Dakota Stockgrowers Association Director Silvia Christen says more than 5 percent of the cattle in western South Dakota might have been killed from the wind and snow of a weekend storm."

On Computers: Hurricanes And Lightning Bolts: New Thinking On Both. Here's an excerpt of a very interesting article at Canton's cantonrep.com: "...This all soon will change. NASA is rolling out a hurricane-hunter jet based on the Air Force’s largest pilotless plane, the Global Hawk. It can spend 20 hours or more loitering inside a hurricane, monitoring conditions by the minute and sending them back to its manned cockpit on land. The “cone of improbability” will shrink to the probable. This could end the lethal surprises, such as tracking Hurricane Sandy’s sudden swing up the East Coast. The immense data flow could enable meteorologists to crack the code of why hurricanes can be so unpredictable. Next step would be Tornado Alley with drones constantly watching for the early signs of twister outbreaks. All this is doable..."

Australia's Brushfire Season Turns Sydney's Skies Orange. Climate Central has the story and video - here's the intro: "Australia has been enduring its hottest year on record, and the warm temperatures combined with dry conditions have sent wildfires whipping across the southeastern Australian state of New South Wales. The fires — some of the worst in a decade — have caused a deep haze to descend over Sydney and spurred the deployment of hundreds of firefighters across the region. Smoke from the fires blanketed Sydney. Surreal images from Quartz show eerie orange skies framing the downtown, harbor, and iconic opera house, making the city look like its been transplanted to Mars. Social media also buzzed with pictures of the lingering smoke. Timelapse videos, including the one above, show Australia’s largest city under the orange haze for much of the day..."

Australia Faces Worst Wildfire Threat In 40 Years. France24.com has an update on the major fires burning in New South Wales, and the potential for more blazes; here's an excerpt: "Australian officials warned Sunday that New South Wales was facing "unparalleled" danger from the worst wildfire conditions in more than 40 years. More than 200 homes have already been destroyed, with weather conditions likely to worsen. Australian fire services warned Sunday that parts of New South Wales were facing the most dangerous combination of warm, dry weather and strong winds in more than 40 years as major wildfires swept the state..."

Why You Need Your Beauty-Sleep. So this is why I get cranky (and even more forgetful) when I don't get a good night's sleep. NPR has a great explanation; here's a clip: "While the brain sleeps, it clears out harmful toxins, a process that may reduce the risk of Alzheimer's, researchers say. During sleep, the flow of cerebrospinal fluid in the brain increases dramatically, washing away harmful waste proteins that build up between brain cells during waking hours, a of mice found. "It's like a dishwasher," says , a professor of neurosurgery at the University of Rochester and an author of the study in Science. The results appear to offer the best explanation yet of why animals and people need sleep. If this proves to be true in humans as well, it could help explain a mysterious association between sleep disorders and brain diseases, including Alzheimer's..."

18-Foot Oarfish Livens Up A "Leisurely Snorkel" In California. I'm feeling even better about Minnesota's wondrous lakes; details from NPR: "A snorkeler off the coast of California found more than she bargained for on the ocean floor Sunday, when she saw the large eyes of an 18-foot fish staring back at her. It turned out to be a dead oarfish, a mysterious creature known to live in waters thousands of feet deep. The discovery at the bottom of Toyon Bay at Catalina Island came as a shock to Jasmine Santana, an instructor at the , who approached the ribbon-like animal with care before realizing it was dead. Its body was "almost perfectly intact," the institute says. It may have died of natural causes..."

Climate Stories...
Saving The Great North Woods. The Star Tribune ran a long, comprehensive, and excellent story about the changes taking place in the North Woods of Minnesota. A slow-motion warming trend is underway, and that has implications for the species of trees that can thrive in the years ahead; here's an excerpt of Josephine Marcotty's article: "...A stark forecast looms for Minnesota’s great North Woods, the mixed hardwood and conifer forest that grew when the glaciers retreated during the last great climate change 12,000 years ago. Driven by a warming climate, scientists predict, the forest will soon follow the glaciers and retreat north by as much as 300 miles in the next century. Much of northern Minnesota, they say, will become open savannas like those in Nebraska and eastern Kansas — with grasses and brush, a few scattered trees, and domes of bare rock rising from the ground. For future generations of Minnesotans who love fishing, canoeing and the sight of a moose in the piney North Woods, that cherished outdoors experience is likely to be the stuff of grandparents’ tales..."

Here, Rajala stands next to one of his giants near Grand Rapids — a 200 year old white pine 12 feet in circumference and 120 feet tall."

Iowa Scientists: Climate Change Affecting Farming. Bloomberg Businessweek has the story - here's the introduction: "More than 150 Iowa professors and climate researchers have signed on to a statement released Friday that says extreme weather patterns caused by climate change are affecting farming, and updated practices are needed to prevent soil erosion and adjust to the new reality. "Every year, evidence has been building in Iowa and around the world that there are consequences to the continued release of large quantities of heat-trapping gases into the atmosphere," said David Courard-Hauri, chairman of the Environmental Science and Policy Program at Drake University, who helped write the statement. This year's weather has been extreme..." (file photo above courtesy of Renee Jones Schneider, Star Tribune).

George Shultz Calls For GOP "Climate Insurance Policy". Here are a few exceprts from a recent story at Clean Technica: "Former Secretary of State George Shultz proposed that the U.S. adopt a "Climate Insurance Policy" to simultaneously bolster the economy and reduce the risk of global warming. In a recent interview with reporters, Shultz suggested that Republican leaders follow a Reagen-era strategy that would drive innovation while also cutting carbon emissions....On Climate, Shultz's policy preference combines sound policy with deft political strategy. It would tend to reduce federal tax and spending levels over time, by shifting taxes from forms of prosperity that tend to go up, to forms of pollution that tend to go down..."

To Fix Climate Change , Scientists Turn To Hacking The Earth. We'll lower emissions before drastic, global geo-engineering becomes the only viable way of reversing climate volatility. Right? Here's a clip from a story at NPR: "...While it scared a lot of people and angered a lot of scientists, this event could be a sign of what's to come. Because some very mainstream scientists are saying that the climate change situation is so bad that saving life as we know it might require something radical: like shooting chemicals into the stratosphere to protect earth from the sun. In essence, these scientists are talking about hacking the climate..."

Insurance Industry Warms To New Climate Report. Here's a clip from Business Insurance: "...When a body like the IPCC concludes that, with 95% certainty, mankind is causing climate change, we would be foolish not to listen,” he said. “And yet, we are still not listening closely enough. The transition to a low-carbon economy and a more climate-resilient society cannot be thought of as options; they are necessities.”
