0″ of snow on the ground as of 7 PM Sunday in the Twin Cities.
February 22, 1922: A blizzard, ice storm and thunderstorms all occur on the same day across Minnesota. Winds hit 50 mph in Duluth while thunderstorms were reported in the Twin Cities. Heavy ice over southeast Minnesota with 2 inches of ice on wires near Winona. Over two inches of precipitation fell. This was also one of the largest ice storms ever in Wisconsin history with ice four inches in diameter on telegraph wires. One foot of ice covered wire weighed 11 pounds. One killed and four injured in Wisconsin.
Minnesota Winters: Fastest Warming in the USA
Isolating the signal from the noise is challenging, yet essential. A single storm or frontal passage is the equivalent of a free throw shot at a Minnesota Timberwolves game. That’s weather. Climate is an analysis of ALL free-throw shots at Wolves games since their founding in 1989. It’s easy to get fixated on a single play, but keep your eye on the big picture; the long-term trends.
Crunching NOAA data Climate Central determined that Minnesota is the fastest warming state in the nation during the winter season. MSP has warmed 1.1F per decade since 1970. So far this winter record highs have outpaced record lows by a 3 to 2 margin across the USA. El Nino is spiking or “juicing” the background warming already underway. That accounts for thin ice on Minnesota lakes in late February.
Don’t write winter off just yet; we’ll see more (fleeting) spasms of frosty air. Models bring a blustery arctic front into Minnesota Saturday; a few subzero lows possible Sunday and Monday before we warm up the first week of March.
Winter is fading fast but I wouldn’t retire that favorite parka just yet.
Every State’s Temperature Trend for Every Season. Yes, Minnesota is warming, especially during the winter months, in fact no other state (except for possibly Alaska) is warming faster. Here’s an excerpt from Climate Central: “...If you look at all four seasons across all of the Lower 48 states — for a grand total of 192 state-season combinations — there are only three instances of cooling. The Dakotas and Iowa are cooling ever so slightly in summer. Otherwise, there’s only one direction temperatures have gone: up. Snow cover in particular plays a role in why winters are heating up so fast from Montana to North Carolina. Or more specifically, it’s a lack thereof. As temperatures rise, snow is decreasing — and in many cases being replaced by rain. Replacing light snow with dark ground means more of the sun’s energy is absorbed leading to a faster increase in warming…”
Decadal Warming Rate. Map above courtesy of WXshift. Minnesota ranks first (since 1970), Wisconsin a close second during the winter season.
How Much Warmer Was Your City in 2015? The New York Times has a terrific interactive page that allows you to find out; here’s an excerpt: “Scientists declared that 2015 was Earth’s hottest year on record. In a database of 3,116 cities provided by AccuWeather, about 90 percent of them were warmer than normal. Enter your city in the field below to see how much warmer it was last year...”
Average Snow Cover in the Twin Cities. 90 days a year with at least 1″ or more on the ground? Here’s an excerpt from Current Results: “For nearly all of winter along with some of early spring and late fall, Minneapolis has at least an inch of snow on the ground. A snowpack that gets to ten or more inches deep can cover the city anytime from November to April. The snow accumulates most during December, January and February. Typically, on six or seven days in January and in February plus another five days in December, the snow depth in Minneapolis tops ten inches…”
Nuisance Snow on Tuesday. Models print out about a tenth of an inch of liquid precipitation Tuesday, which may translate into a coating to an inch of (slushy/sloppy) snow. With temperatures above 32F most roads will probably be wet. 84-hour NAM accumulated snowfall forecast: NOAA and AerisWeather.
About As Exciting As It’s Going to Get Anytime Soon. A “storm”? Old-timers might call it “flurries”. Any big storms detour well south and east of Minnesota into the first week of March; a fading (but still significant) El Nino signal helping to keep us drier and milder than average, overall, the next couple of weeks.
A Sharp, Quick Arctic Smack. No prolonged polar air; the sun is too high in the sky now and the pattern doesn’t favor an extended spell of shivering. But cold air is building and there’s a good chance Sunday and Monday will bring back memories of January. 10-day 2-meter GFS temperatures: NOAA and AerisWeather.
Parka Weather. Models show subzero wind chills late Saturday into Sunday morning, as cold as -13 to -27 by 7 AM Sunday. Something to look forward to. Graphic: Aeris Enterprise.
One More Wintry Slap. If it’s any consolation any pain will be brief, and it won’t be nearly as cold as it was back in mid-January. After a sloppy mix Tuesday with highs near 40F temperatures run close to average, until Tuesday when a sharp cold frontal passage whips up 20-40 mph winds and tumbling temperatures. The 11th (and probably last) night below zero in the metro may come Sunday morning before a rapid rebound next week. Graphic: WeatherSpark.
Will the Minnesota River Flood This Spring? Less snow cover, less frost in the ground – the potential for (river) flooding now hinges on the risk of heavy rain and snow in March and April. Here’s an excerpt from The Chaska Herald: “…The NWS report notes that the area had a wet November and December followed by a drier January and February, with a below-normal snow pack and frost depth. With spring flooding, the “main driver” will be heavy rain fall in areas with high soil moisture. In the Minnesota River valley, that means a “slightly above normal” chance for spring flooding. “Especially from the Redwood River downstream,” notes the NWS report…”
Tropical Cyclone Winston Makes Category 5 Landfall; Strongest on Record in Fiji. Here’s a link to a terrific explainer and story update at The Weather Channel: “…Tropical Cyclone Winston raked across Fiji Saturday with Category 5 winds, the strongest landfalling tropical cyclone on record in the South Pacific archipelago. Winston is now located west of Fiji and is forecast to curl southward away from land while weakening the next few days. According to the U.S. Joint Typhoon Warning Center (JTWC), Winston made landfall along the north coast of Fiji’s largest, most populous island, Viti Levu, Saturday evening, local time (Fiji is 17 hours ahead of U.S. Eastern standard time), packing estimated maximum sustained winds of 180 mph…”
Weather Wise: How Are Tornadoes Identified? New dual-polarization Doppler is so sensitive it can track tornado debris lofted into the air, helping to confirm that a tornado is, in fact, on the ground. Here’s an excerpt from Florida Today: “…But how do meteorologists know if a tornado has touched down or not? Obviously, eyewitness accounts or footage could help confirm things, but given that it was dark and the rotation was seen initially in an area without much, if any population, that wasn’t to be. Instead, during an event, forecasters look for a tornadic debris signature on radar. “If there is a tornadic debris sign on radar, that will give us confirmation,” Kelly said. “At that point, we would update the warning probably to OK, we have more confidence now that there is a tornado on the ground.” Kelly adds that the strength makes the debris signatures “more pronounced.” Essentially, the higher that the debris field is, the stronger the tornado is...”
El Nino Weakening, Stage Set for La Nina and Possible Dry Winter Next Year. The pendulum may be about to swing in the opposite direction. Here’s an excerpt from KQED Science: “Federal climate scientists say the near-record El Niño conditions in the Pacific Ocean have peaked and are slowly waning. Forecasters now say conditions are likely to flip to their opposite phase, known as La Niña by late summer or early fall, which could set the stage for another drier-than-normal winter and prolonged drought in California. “We are reasonably confident that there will be a La Niña,” says Huug van den Dool, seasonal forecaster at NOAA’s Climate Prediction Center, “but we plead ignorance as to whether this is going to be a small, moderate, or strong La Niña…” (Image above: NOAA NCEP).
El Nino is Causing Global Food Crisis, UN Warns. Here’s an excerpt from The Guardian: “…Severe droughts and floods triggered by one of the strongest El Niño weather events ever recorded have left nearly 100 million people in southern Africa, Asia and Latin America facing food and water shortages and vulnerable to diseases including Zika, UN bodies, international aid agencies and governments have said. New figures from the UN’s World Food Programme say 40 million people in rural areas and 9 million in urban centres who live in the drought-affected parts of Zimbabwe, Mozambique, South Africa, Zambia, Malawi and Swaziland will need food assistance in the next year…”

How America Is Putting Itself Back Together. Is America as big a basket base as some presidential candidates would like us to believe? The jury is out, but James Fallows renewed my abiding faith in the USA in his essay at The Atlantic; here’s an excerpt: “…As a whole, the country may seem to be going to hell. That jeremiad view is a great constant through American history. The sentiment is predictably and particularly strong in a presidential-election year like this one, when the “out” party always has a reason to argue that things are bad and getting worse. And plenty of objective indicators of trouble, from stagnant median wages to drug epidemics in rural America to gun deaths inflicted by law-enforcement officers and civilians, support the dystopian case. But here is what I now know about America that I didn’t know when we started these travels, and that I think almost no one would infer from the normal diet of news coverage and political discourse...”
Postcards From The Astronaut’s Lounge. Why are Bezos, Musk and Branson so obsessed with The Great Beyond? WIRED has a revealing story; here’s the intro: “Space. It’s a funny thing. Kubrick knew that. Because if you start a story with apes, how can it not be funny? Then again, doesn’t everything that’s about humans start with apes? Here’s the funny thing about space: Ask people what they think about it and you’ll get every kind of answer. We should colonize Mars! We should stay home! We should look for life! Space, really, is a giant Rorschach. Into it we send rockets and satellites and space stations. But more than that, we send beliefs. About what is meaningful. About what is possible. About what is inescapable…”
Newsonomics: The Financialization of News is Dimming The Lights of The Local Press. Ken Doctor has a long and intriguing essay at NiemanLab about the struggle to develop new platforms and business models to support a digital-first strategy; here’s an excerpt: “…There’s no easily assembled formula yet, but the parts of it have become clearer over the past several years. It is those national/global players that have begun to master new disciplines in this new age of AMP, Arc and analytics. Why? Certainly, it’s easier for them to take advantage of digital’s natural opportunities for scale. They also increasingly put data science (which leads to audience knowledge and development) at or near the centers of their business. That leads them to intelligent experimentation with the platforms of the moment (Facebook, Apple, Google, Snapchat) while local media hardly play (“As giant platforms rise, local news is getting crushed”)...”
Wireless: The Next Generation. 5G is coming. Can you hear me now? Here’s an excerpt of what we might expect from The Economist: “…The advent of 5G is likely to bring another splurge of investment, just as orders for 4G equipment are peaking. The goal is to be able to offer users no less than the “perception of infinite capacity”, says Rahim Tafazolli, director of the 5G Innovation Centre at the University of Surrey. Rare will be the device that is not wirelessly connected, from self-driving cars and drones to the sensors, industrial machines and household appliances that together constitute the “internet of things” (IoT)...”
From Georgia to Maine: What I Learned on a 6-Month Hike Along the Appalachian Trail. Here’s an excerpt of an interesting and vaguely terrifying tale at The Washington Post: “…The scariest moment on the trail was not, as many people often guess, bear-related. Rather, it was the weather. Team Pie, with the temporary addition of a real-life friend named Gary, was headed over Kinsman Mountain in the White Mountains of New Hampshire. The August weather was stunning — just a bit chilly, bright with sunshine. The weather report had said that there was a chance of rain later…”

Profound and intractable as the city’s sanitation problems are, the precise risks to Olympic athletes competing on any given day this summer are hard to calculate. Some got sick at sporting test events last year, but none of these cases has been publicly, definitively connected to the water, as opposed to food or another source. “Epidemiology is a science of population health, not individual health,” says Joseph Eisenberg, a University of Michigan professor of epidemiology who studies waterborne disease pathways. “It’s statistical association, not deterministic.” In the event of a large-scale outbreak, suspect environments would be tested, he says. But no team of scientists in hazmat suits rushed to the scene to investigate the microbes that caused stomach bugs in a smattering of athletes…”

Short-Term Climate Sensitivity on Vegetation Productivity. Certain ecosystems appear to be more vulnerable than others, according to research highlighted at MicroCap Magazine: “…Seddon, adds, “We have found ecologically sensitive regions with amplified responses to climate variability in the Arctic tundra, parts of the boreal forest belt, the tropical rainforest, alpine regions worldwide, steppe and prairie regions of central Asia and North and South America, forests in South America, and eastern areas of Australia.” The researchers say they have developed a quantifiable response measurement, called the Vegetation Sensitivity Index (VSI), that can show how ecosystems are challenged by short-term climate anomalies, such as a warmer June than the average, a colder December, or even a cloudy September. The team says the index can supplement other methods of monitoring and evaluating the health of ecosystems across the globe…” (Map credit: Verisk Maplecroft 2014).
January 2016 Shattered the Global Warming Monthly Record. Symptoms of El Nino, and background warming which continues to accelerate. Here’s an excerpt from Newsweek: “The global temperature anomaly for January 2016 was 1.13° Celsius. That makes it the hottest January on record (the previous record was 0.95° C in 2007). But there’s more: 1.13° is the largest anomaly for any month since records began in 1880. There have only been monthly anomalies greater than 1°C three times before in recorded history, and those three were all from last year. The farther back in the past you go, the lower the anomalies are on average. Yes, the world is getting hotter…”
Earth Kicks Off 2016 With the Most Abnormally Warm Month Ever Measured. This is more than El Nino. El Nino is standing on your tip-toes at the top of a flight of steps. Many are forgetting about the flight of stairs we’re going up. Here’s an excerpt at Slate: “It would be hard to top 2015—a year unlike any other in human history—but 2016 seems to be giving it a shot. According to the latest data from NASA, issued over the weekend, January was the planet’s most unusually warm month since we started measuring temperature in 1880. No other month in the preceding 1,633 months has deviated this far from what was once considered “normal.” Data independently produced by Japan’s Meteorological Agency confirmed that last month was the hottest January on record globally. Last month broke the all-time January record by the widest margin of any month on record, a full one-third of a degree ahead of last year’s record pace. That means the planet is already on track for an unprecedented third straight year of record-setting temperatures…”

Catholic “Climate Cardinal” Says Florida Politicians Have Duty to Act. Here’s the intro to a story at The Miami Herald: “Florida politicians have a duty to address the perils of climate change even if they don’t believe humans are hastening its grave consequences, Pope Francis’ chief advisor on climate change said Friday. In an interview with the Herald before addressing a conference on climate, nature and society at St. Thomas University law school, Cardinal Peter Turkson said, “Anybody running for public office who sees the life of the people affected by climate-related disasters” needs to act. That, he said, includes the state’s two Republican presidential contenders who remain skeptical of the science tying climate change to increased carbon emissions…” (File photo of Miami: Wikipedia).
