Friday Slush for MSP - Blizzard Watch Out West

Yesterday the FedEx guy showed up in shorts and a short-sleeve shirt. "Can you believe this weather, Paul?" he asked, beaming from ear to ear. I expect muffled applause to die down by Friday, as the first big winter storm of the season rolls across the state.

With a rapidly intensifying storm tracking directly over MSP I don't expect heavy snow in the immediate metro, but much of northern and western Minnesota should see a plowable accumulation, whipped into towering drifts by 45 mph wind gusts. Blizzard Watches are posted for western Minnesota, where travel conditions could range from treacherous to impassable by Friday afternoon. Roads will be increasingly slushy and icy the farther north and west you travel from MSP on Friday.

Coming after the warmest start to November on record it will feel like a cold slap across the face.

Skies clear Saturday with weekend highs in the 30s. Models suggest a light mix Tuesday night, again Friday, but no major storms to complicate travel plans.

The first freeze at MSP comes Saturday, a 221-day frost-free growing season in 2016. Wow. 

Blizzard Watch Western Minnesota and Eastern South Dakota. You may want to think twice about driving into western Minnesota or toward Watertown, Brookings or Aberdeen, South Dakota on Friday. The combination of heavy snow and high winds will create treacherous condiitions. Details:


NAM/WRF Solution. Here is NOAA's high-resolution 4km model, showing the axis of heaviest snow from eastern South Dakota to Bemidji and International Falls; as much as 12-18" of snow predicted. Map credit: WeatherBell.

GFS Solution. NOAA's GFS solution shows the heaviest snow band farther north than the NAM/WRF model, some 10-16" amounts from near Fergus Falls and Bemidji into the Minnesota Arrowhead.

European Solution. The ECMWF ("Euro") pulls the axis of heaviest snow into far southwestern Minnesota; more impressive overall, with 8" predicted for Brainerd, closer to 12" at Alexandria and a cool 15" for Bemidji. A coating is possible in the MSP metro, maybe a quick 1-2" on lawns and fields by late Friday.

Future Radar. NOAA's 4km NAM model pulls rain into Minnesota Thursday night, changing over to snow from west to east during the day Friday. By the time the atmosphere is cold enough for accumulating snow (ground temperatures and the lowest mile of the atmosphere <32F) most of the moisture will have cut off in the immediate Twin Cities. But for much of western, central and northern Minnesota there should be enough snow to get snow-lovers (and you know who you are) very excited. Loop: AerisWeather.

Windblown Friday. Internal models show winds gusting over 40 mph across much of western Minnesota Friday, capable of producing white-out conditions from Marshall and Windom to Alexandria and Wadena. Source: AerisWeather AMP.

Peak Gusts. Here are a few of the towns that may experience blizzard conditions by Friday. A blizzard is defined as 35 mph winds (sustained) for at least 3 consecutive hours, capable of producing low visibility, under 1/4 mile. We could easily have those conditions over much of western and northern Minnesota Friday.

GFS Loop. Here's NOAA's GFS solution, suggesting a plowable snowfall across far western, central and northern Minnesota. The central Rockies and Dakotas will also pick up enough snow to get snow lovers excited. Animation: AerisWeather.

Thanksgiving Day Weather. Here is the European solution, valid midday next Thursday, showing showery rains for the Mid Atlantic region; maybe a mix for upstate New York. Heavy rain will push into the Pacific Northwest, but the rest of the USA looks relatively dry and quiet on Turkey Day. No mega-storms brewing just yet. Source: WSI.

NOAA: U.S. Snowcover Hits an "All-Time Low" for November. Here's the intro to an explainer at Engadget: "Researchers just supplied more evidence that climate change-related temperature increases are having a material effect on the planet. America's National Oceanic and Atmospheric Administration reports that snow cover in the lower 48 states is the lowest ever recorded for mid-November. As you can see in the map below, there's very little snow on the ground in the country -- you'd likely have to climb a mountain to see it. For contrast, the average snow cover between 1981 and 2010 reached as far south as New Mexico..."

Second Warmest October Cements Hottest Year. Climate Central has an update: "...But even La Nina years now are warmer than El Niño years several decades ago because of the long-term warming caused by carbon dioxide and other heat-trapping gases emitted into the atmosphere. Because of the combination of El Niño and manmade warming, 2016 will best 2015 as the hottest year on record, the third record-warm year in a row, the World Meteorological Organization told delegates at the U.N. climate meeting in Morocco..."

Smoke From a Siege of Wildfires Spreading Across the Southeastern USA Is Easily Seen From Orbit. Details via Discover Magazine: "Spurred on by intensifying drought, wildfires continue to spread across portions of the southern United States, sending up palls of smoke that are easily visible from orbit. In the image above, acquired by the Suomi NPP satellite on November 12, the thickest plumes are rising from fires in the southern Appalachians within North Carolina and Georgia. But smoke from fires in Virginia, Kentucky, Tennessee, and South Carolina is also visible..."

A Heartbreaking Hurricane. Hurricane Katrina is linked to heart attacks many years after the storm, according to an analysis at Nexus Media: "...Irimpen and his colleagues also found that patients were significantly more likely to have other risk factors for heart attack post-Katrina than before the hurricane, including coronary artery disease, diabetes, high blood pressure and high cholesterol. They were also more likely to be smokers. The researchers found that these patients were more than twice as likely to abuse drugs, or suffer from a psychiatric disease as their pre-Katrina counterparts. Moreover, unemployment and lack of health insurance were significantly more frequent among the post-Katrina patients, he says. Post-Katrina patients also were more likely to receive prescriptions for medications to treat heart disease, cholesterol and hypertension, but were only half as likely to take them compared to the pre-Katrina group, he says..."

Will Rising Sea Levels Sink Property Values? Here's an excerpt from Yahoo! Finance: "...But many people don’t realize that investing in waterfront property now may lose them money, in much the same way as splurging on an expensive car would: depreciation. The reason? Rising sea levels are eroding the long-term value of such properties. “Once impacts become noticeable, they’re going to be upon you quickly,” William V. Sweet, a scientist with the National Oceanic and Atmospheric Administration in Silver Spring, Maryland, told The New York Times. “It’s not a hundred years off — it’s now.” Sea levels are rising, according to scientists, due to global warming, as rising atmospheric and ocean temperatures melt polar ice caps and glaciers. Even skeptics of the phenomenon may find it difficult to argue with the “sharp jump in this nuisance flooding,” currently impacting the East Coast and Gulf Coast. Expect more flooding in those areas and the West Coast, too, according to The Times report..."

The History of Weather Satellites. AccuWeather has an interesting post - yes, we've come a long way, and GOES-R marks the next big evolutionary leap: "The science of weather forecasting has come a long way over the past 100 years, but one of the biggest leaps forward occurred once information from weather satellites was readily available. Weather satellites have had such a huge impact on weather forecasting that some divide the history of meteorology into two categories: pre-satellite era and post-satellite era. Weather satellites provide invaluable data to meteorologists all around the world, not only by sending forecasters images of weather systems but also by supplying weather models with remote observations in places where observations cannot be taken at the Earth's surface..."

How Wind and Solar Plan To Thrive During the Trump Presidency. Here's an excerpt from a story at Utility Dive: "...Our industry will be fine,” Sunnova CEO John Berger told Utility Dive. Sunnova is one of the leading national rooftop solar providers. “Business models will change and the companies that can’t deliver a better service at a better price won’t make it.” Losing its 30% federal investment tax credit (ITC) might even provoke constructive change, Berger said. “But with or without the ITC, this industry will thrive and that is because we are quickly driving down the cost of solar and solar components and now the cost of batteries is coming down as fast...” Image credit: NAHB livestream

Biofuel From Logging Scraps Powers Alaska Airlines Jet on Cross-Country Flight. I haven't seen this before. Here's the intro to a story at The Seattle Times: "An Alaska Airlines flight from Seattle to Washington, D.C., on Monday morning was powered with a jet-fuel blend containing 20 percent renewable biofuel made from Pacific Northwest forest residuals — the limbs and branches that remain after the harvesting of managed forests. Billed as the first commercial flight running partly on wood, the alternative jet fuel was produced through the research efforts of the Northwest Advanced Renewables Alliance (NARA). Led by Washington State University, the group aims to build a sustainable supply chain for aviation biofuel using the leavings from logging operations..."

It's Hard To Tell Whether Trump Supports Renewable Energy - And That May Not Matter Much. Here's an excerpt from a post at FiveThirtyEight: "...Job creation is a key part of bolstering that capital. Just over 600,000 Americans are employed in industries related to alternative energy1 — not including the 1.9 million employed in the energy efficiency industry, which is aimed at reducing the amount of energy people have to use for services like transportation, or home heating and cooling. The solar and wind industries account for about 61 percent of those jobs. There are far more people employed in all the industries related to fossil fuels, 3.6 million in the U.S. in total. But 600,000 jobs is a big deal to the American economy..."

These 6 New Technology Rules Will Govern Our Future. Here's a clip from a story at The Washington Post that got my full attention: "...In every field, machines and robots are beginning to do the work of humans. We saw this first happen in the Industrial Revolution, when manual production moved into factories and many millions lost their livelihoods. New jobs were created, but it was a terrifying time, and there was a significant societal dislocation (from which the Luddite movement emerged). The movement to digitize jobs is well underway in low-salary service industries. Amazon relies on robots to do a significant chunk of its warehouse work. Safeway and Home Depot are rapidly increasing their use of self-service checkouts. Soon, self-driving cars will eliminate millions of driving jobs. We are also seeing law jobs disappear as computer programs specializing in discovery eliminate the needs for legions of associates to sift through paper and digital documents..."

A Brief History of the Cheese Curl, Junk Food's Happiest Accident. Atlas Obscura has an article that will make you hungry, for orange-colored food - here's a clip: "They change the color of our skin. They get stuck in our teeth. But for some reason, we can’t stop eating cheese curls, the puffiest snack food ever created. But these corn-and-powder snacks didn’t just fall like manna from the sky into our bowls, always there for us ahead of our Bojack Horseman marathon. The story of the cheese curl is one of the more unusual creation stories in snack-food history, starting, of course, in Wisconsin, an agricultural hub that has given us a lot of food innovations over the years.."

Climate Stories

WMO: Past 5 Years Hottest on Record, Worldwide. Here's an excerpt from a story at Fusion: "...On November 8, the World Meteorological Organization (WMO) delivered a report at the international conference on climate change in Morocco (COP22) which was called in order to carry forward the Paris agreement of COP21. The WMO reported that the past five years were the hottest on record. It reported rising sea levels, soon to increase as a result of the unexpectedly rapid melting of polar ice, most ominously the huge Antarctic glaciers. Already, Arctic sea ice over the past five years is 28% below the average of the previous 29 years, not only raising sea levels, but also reducing the cooling effect of polar ice reflection of solar rays, thereby accelerating the grim effects of global warming..."

Military Leaders Urge Trump To See Climate As a Security Threat. Scientific American has the story; here's an excerpt: "...The Center for Climate & Security in its briefing book argues that climate change presents a risk to U.S. national security and international security, and that the United States should advance a comprehensive policy for addressing the risk. The recommendations, released earlier this year, were developed by the Climate and Security Advisory Group, a voluntary, nonpartisan group of 43 U.S.-based senior military, national security, homeland security and intelligence experts, including the former commanders of the U.S. Pacific and Central commands. The briefing book argues that climate change presents a significant and direct risk to U.S. military readiness, operations and strategy, and military leaders say it should transcend politics. It goes beyond protecting military bases from sea-level rise, the military advisers say. They urge Trump to order the Pentagon to game out catastrophic climate scenarios, track trends in climate impacts and collaborate with civilian communities..." (File photo: AP).

Military, Security Leaders Deliver Climate Change Briefing Book to President-Elect. Here's the intro to an update from The Center for Climate and Security: "In the wake of last week’s election, the Center for Climate and Security is delivering a Briefing Book for a New Administration to the President-elect. The book of recommendations was developed by the Climate and Security Advisory Group (CSAG), a voluntary, non-partisan group of 43 U.S.-based senior military, national security, homeland security, and intelligence experts, including the former Commanders of U.S. Pacific and Central Command, and former Special Assistant to President Reagan for National Security Affairs. Climate change presents risks that must be managed, no matter one’s political perspective..."

DC Prepares For Heat Emergencies To Nearly Double by 2020, Among Other Climate Change Effects. Here's a clip from DCist: "...D.C. currently experiences around 11 heat emergency days per year, which could almost double to 20 days by 2020 and spike up to 75 days by 2080, according to the report. Washingtonians should also expect much warmer average temperatures; longer, hotter, and more frequent heat waves; and more frequent and intense heavy rain and flooding. The city has already begun to see record-breaking heat waves and snowstorms as well as flooding caused by rising sea levels and high rainfall. Climate Ready DC, the city's readiness plan, looks at current weather patterns and predicts how they will change by 2080. The report, which was developed by consulting with experts inside and outside of District government, then outlines the city's strategies to adapt..." Photo credit: SweetJen34

The End of Ice. Check out the photo essay at New Republic: "...The peculiar physics of climate change have played a particularly nasty trick on those who live farthest to the north. The steady, relentless stream of data from satellites, weather buoys, and remote weather stations makes it clear that the Arctic—which has supported human life for millennia—is warming twice as fast as any place on the planet. But you don’t need data to understand what’s happening: Pictures will do..."

40 Years of Measuring the World's Cleanest Air Reveals Human Fingerprints on the Atmosphere. Here's an excerpt from The Conversation: "...Cape Grim data are freely available and have been widely used in all five international climate change assessments (1990-2013), all ten international ozone depletion assessments (1985-2014), in four State of the Climate Reports 2010-2016 and in lower-atmosphere ozone assessments. Measurements at Cape Grim have demonstrated the impact of human activity on the atmosphere. For example, CO₂ has increased from about 330 parts per million (ppm) in 1976 to more than 400 ppm today, an average increase of 1.9 ppm per year since 1976. Since 2010 the rate has been 2.3 ppm per year. The isotopic ratios of CO₂ measured at Cape Grim have changed in a way that is consistent with fossil fuels being the source of higher concentrations..."

Why Arctic Waters Are Reluctant to Freeze. The Guardian explains: "...Much of the reason for these warm temperatures and the sluggish rate of sea-ice formation is the exceptional summer sea-ice melt that occurred this year. By 10 September the National Snow and Ice Data Center reported that Arctic sea-ice had shrunk to an area of just 4.14m square kilometres – tying with 2007 for second lowest sea-ice extent on record, and some 740,000 square kilometres short of the record set in 2012..."
