Relatively Quiet Black Friday for Shoppers (snow potential increases central USA next week – bitter blast 1 week away?)

29 Nov 2013, 9:18 am



Storm Incubator. The map above from NOAA shows predicted 500 mb heights (streamlines) between December 4-8, a southwesterly wind component aloft capable of whisking a series of storms across the Plains. As temperatures progressively cool down the atmosphere should be cold enough for (all) snow by the end of next week.


Wednesday Night – Thursday: Wintry Mix? The ECMWF map above (WSI) valid midnight Wednesday night shows a storm tracking across Iowa, enough warm air flowing north for a possible mix of rain, sleet and snow from central Minnesota southward to the Iowa border. It’s too early for more specifics – and the forecast WILL change over time as new, higher resolution data initializes the models.


Friday PM Hours: All Snow. Again, this is all still highly speculative (it always is), but ECMWF guidance shows a second storm rippling north along a vigorous cold frontal boundary pushing across the central USA, with enough cold air in place for another wave of snow late Friday into Saturday morning. If temperatures are in the teens or single digits this could be a dry, powdery snow, prone to blowing and drifting.


8-Day Snowfall. Here is the latest NAM solution showing NOAA’s prediction for 8-Day snow accumulations; the best chance of a healthy pile of (very) plowable snow from eastern Nebraska and the eastern Dakotas into the northwest half of Minnesota. Map: Ham Weather.


8-Day Blizzard Potential Index. I start to get nervous anytime our calculated in-house Blizzard Index goes above 3.0. Again, it’s still very early to be making sweeping pronouncements, but conditions may be ripe for blizzard or near-blizzard conditions across the Dakotas and portions of western and northern Minnesota the latter half of next week.

Cold Weather Myths. What Do You Really Know About Staying Warm? A few of these were a (big) surprise to me, to be honest. As we track the deepening chill we attempt to address a few cold weather myths: any scientific validity to back up these claims? That’s the subject of today’s Climate Matters: “Meteorologist Paul Douglas has your cold weather trivia. The myths we have grown up believing about the cold weather! These clues will help you stay warm as the coldest air mass of the season is looking to set in the first week in December. Brrr…. Happy Thanksgiving and Happy Hanukkah! These two holidays fall on the same day this year, a very rare occurrence that will not happen again for many years to come.”


In Spite Of Nagging Drought – 2013 Was Second Best Year For Farming Since 1973. Here’s an excerpt of a good summary from CNBC: “…In crop projectiongs this month, the USDA increased its estimated total for corn to 1 percent over last year’s estimate, and soybean production up 3 percent from the 2013 estimate. Corn will see total production at a record level of nearly 14 billion bushels. Those higher estimates came despite many areas of Iowa, Minnesota and the Upper Midwest dealing with late planting, along with some late-season drought conditions. Net farm income is also on the rise. It’s forecast to be $120.6 billion in 2013, up 6 percent from 2012’s estimate of $113.8 billion. After adjusting for inflation, 2013’s net farm income is expected to be the second highest since 1973, according to the USDA...”

Growing Signs Of El Nino In 2014. The graphic above is from NOAA’s latest ENSO update; after years of a perpetual La Nina cooling phase of the equatorial Pacific there are growing signs of a possible El Nino warming phase developing by early 2014; which may, in turn, favor milder than normal temperatures, and a southern storm track across the USA into the latter half of winter. It won’t be declared an official El Nino event until and unless we go at least 3 consecutive months with sea surface temperatures .5C warmer than average.


Battling Flames In Forests, With Prison As The Firehouse. The New York Times has the story of how many states are throwing more manpower on the front lines of major wildfires; here’s an excerpt: “…As federal agencies have cut costs during the budget standoffs in Washington, further decreasing the size of a firefighting work force that has already been reduced by 40 percent since the 1980s, the burden of fighting wildfires has been shifted to states and local jurisdictions, even as they struggle under the weight of a sluggish economy. Prison crews, cheap and dependable, have emerged as a solution as wildfires burn bigger, hotter and longer each year and take up a growing portion of the United States Forest Service budget. (In 2012 alone, federal agencies spent $1.9 billion on wildfire suppression, just shy of the record, set in 2006.)…” (Photo above: Grand Junction office of the National Weather Service).


The Daniel Fast: A Diet From God? Step away from the turkey – just fruit and vegetables going forward, ok? Here’s a clip from an interesting story at The Atlantic: “…Daniel said he and his friends would eat a diet of only vegetables (“pulse”). After 10 days, they grew healthier and stronger than the Babylonians, and his diet became a small demonstration of his opposition to the King’s power. This passage is occasionally used to encourage Christians to resist the corrupting influences of the outside world. But several years ago, some Protestant churches began to take the “diet” aspect of Daniel’s story literally. Motivated by both faith and fitness, today many protestant Christians around the country are, like Daniel, occasionally limiting themselves to fruits and vegetables for 21-day increments…”

“Action”: From Sports Star To TV Star. The New Yorker has a fascinating article about how ESPN grooms it’s on-air talent, making that hard turn from sports star to TV “personality”; here’s the excerpt: “…ESPN, the Megalodon of sports broadcasting, has no shortage of retired millionaires sending job applications: both the N.F.L. and the N.B.A. host annual seminars for players interested in broadcasting, and a current Pittsburgh Steeler recently asked if he could work as an unpaid intern. But finding linebackers who understand the difference between B-roll and a boom mike can be difficult. “They go from a job where you’re trained to say as little as possible to a job where you need to say as much as possible,” Gerry Matalon, a senior producer who helps run ESPN’s on-air talent development, said recently. In 2008, to remedy the problem, ESPN created a talent department staffed with several performance coaches like Nash…”



Climate Stories…

The Sound Of Global Warming: Melting Glaciers Sizzle In Warm Water. Science World Report has the article; here’s the intro: “What does global warming sound like? Scientists may have just found that out. They’ve recorded and identified the sizzle of glacier ice as it melts into the seas. The noise, caused by trapped air bubbles squirting out of the disappearing ice, could provide clues to the rate of glacier melt and help researchers better monitor fast-changing polar environments…”

Can You Talk Turkey With Your Climate-Change-Denying Relatives This Thanksgiving? After reading this (and checking out the video) I wasn’t sure whether to laugh or weep; here’s an excerpt from Huffington Post: “…Thanksgiving is coming and you know what that means, folks: dinner with your climate-change-denying relatives. You know who I’m talking about. The uncle who thinks sunspots are the reason the planet’s getting warmer. The cousin who thinks dinosaur farts are to blame. Grandma, who also thinks President Barack Obama is a lizard from space. Maybe you try to avoid these conversations at your Thanksgiving dinner. But there usually comes a point in the evening when, having exhausted all conversation about how lovely the new trivet is and yes, the traffic yesterday was just the worst, other topics come up. Sometimes you start talking about the weather … and then all of a sudden you’re arguing about whether Al Gore’s breath is really the reason it’s been so hot lately…”


Chris Hadfield: We Should Treat Earth As Kindly As We Treat Spacecraft. Here’s an excerpt of a thoughtful, timely piece from NASA astronaut Chris Hadfield, in Wired Science: “…While I was on the space station, I used Twitter to ask hundreds of thousands of people what they would like me to take a picture of. Resoundingly, the answer was “home.” Everyone, from all around the world, wanted to see their hometowns. I found that thought-provoking. After millennia of wandering and settling, we are still most curious about how we fit in and how our community looks in the context of the rest of the world. A curiosity of self-­awareness, now answerable by technology. This is where the answers to our problems will start…”

Solar Energy Was America’s Sole New Power Source In October. My dream (among others) is to be able to power my Tesla Model S, for free, with affordable solar power and battery storage in my garage. That day may be fast approaching. Here’s a clip from The Atlantic: “In October, power plants generating 530 megawatts of electricity came online in the United States. And every single electron put on the grid came from the sun, according to a report released today. It’s possible to make too much of the fact that solar energy was the sole source of new electricity capacity in US that month. After all, the completion dates of power plants can be random. That’s particularly true for complex, multibillion-dollar, fossil fuel power stations that can take years to build and are subject to oversight by state regulators…”

High Intensity “Megafires” A New Global Danger. Here’s an excerpt (and video clip) from VOA, Voice of America: “..”


How High Will Sea Levels Rise? Let’s Ask The Experts. Here’s a snippet from a comprehensive article at The Washington Post: “…So here’s one way to get a better sense for the broader debate: A new study in Quaternary Science Reviews simply asked 90 experts on sea-level rise for their projections, based on their work. This isn’t brand-new scientific research, but it does give a very useful overview of the current state of research. The results? The experts, on average, think global sea levels will rise somewhere between 0.7 and 1.2 meters by the end of the century if global warming continues unchecked (that’s between 2.2 and 4 feet)…”


Acidifying Oceans Alarm Hundreds Of Scientists. Here’s a clip from a story at Environment News Service: “…Climate change is causing the world’s oceans to acidify at rates not seen for the last 55 million years, and the only way to moderate this danger is to reduce human emissions of carbon dioxide, conclude 540 scientists from 37 countries in a new report. Their conclusion is the outcome of the Third Symposium on the Ocean in a High CO2 World that took place in Monterey, California in September 2012. The findings of these experts were presented in a report to the Conference on Climate Change that took place in Warsaw from November 11 to 22…” (Photo credit: Alamy).

Welcome to the WeatherNation blog. Every day I sift through hundreds of stories, maps, graphics and meteorological web sites, trying to capture some of the most interesting weather nuggets, the stories behind the forecast. I’ll link to stories and share some of the web sites I use. I’m still passionate about the weather, have been ever since Tropical Storm Agnes flooded my home in Lancaster, PA in 1972. I’ve started 5 weather-related companies. “EarthWatch” created the world’s first 3-D weather graphics for TV stations – Steven Spielberg used our software in “Jurassic Park” and “Twister”. My last company, “Digital Cyclone”, personalized weather for cell phones. “My-Cast” was launched in 2001 and is still going strong on iPhone, Android and Blackberry. I sold DCI to Garmin in 2007 so I could focus on my latest venture: WeatherNation. I also write a daily weather column for The Star Tribune And if you’re on Twitter, you’ll find me @pdouglasweather.
