Snow Drought Drags On (couple of slushy inches by Saturday night?)

Posted by: Paul Douglas Updated: December 5, 2012 - 9:40 PM

 

Snow Drought

"Paul, why can I still see my puke-colored lawn on December 6?" Proving cause and effect with something as complicated as the atmosphere is always problematic, but my gut? Drought. With a dash of climate change thrown in for good measure.

Some numbers: we should have seen 11.5 inches of snow by now. Last year 7.8 inches of fluff had already fallen. So far in 2012? A whopping 8 tenths of an inch of snow.

Heating degree data from the National Weather Service shows a warm bias since July; we've saved about 11 percent on heating bills during that period. It feels like December in Tulsa. Again.

Snowy rumors are filling the airwaves for this weekend. My advice? Keep your expectations low. Saturday still appears to be the better travel day; a streak of wet snow may drop an inch or two of slushy snow Saturday night and early Sunday; heavier snow possible just outside the metro area. Plowable up north? Perhaps. Here at MSP? Enough slush to stare out the window and pretend it's winter.

Significantly colder air arrives by mid-December; highs in the 20s. Another storm late next week may drop a light accumulation; once again the best chance north of the cities.

At this rate Santa may have to ditch the sleigh for a big, red SUV. Don't give up on a white Christmas just yet. I haven't.

 

Snowfall Departure From Normal. The MSP metro area is running a 10.7" snowfall deficit, to date. Even Duluth and International Falls are seeing a snowfall slump; the only (reliable) snow coming from lake effect downwind of Lake Superior.

 

72 Hour Snowfall Prediction. WSI's high-res "RPM" model is printing out some 2"+ amounts over central and southern Minnesota by Saturday night, maybe as much as 3-5" south and west of the Twin Cities. Not buying it just yet, but there's certainly a chance of accumulating snow this weekend.

 

USA Snowcover Comparison. The (NOAA) map in the upper left is from December 5, 2010, snow on the ground as far south as the Carolinas, significant snowcover over Minnesota and Wisconsin. 38% of the USA had snow on the ground 2 years ago. The map in the upper right shows a thin gruel of snowcover from Montana and North Dakota into Minnesota's BWCA and the U.P. of Michigan, resembling something out of early October, rather than early December, with snow reported over just 7% of the Lower 48.

 

Where's The Snow? According to NOAA a little over 7% of the Lower 48 have snow on the ground. You have to drive up into far northern Minnesota to see a covering of white, which is a bit off for early December, a little more than 2 weeks from the Winter Solstice. Last year at this time snow was reported over 29% of the USA (exclusing Alaska and Hawaii).

 

Glimmers Of Hope For Snow Lovers? Last winter was a dud (for snow lovers, at least). Minnesotans who aren't fond of snow or cold were relieved - anyone with skis or a snowmobile was in a funk for most of the winter. It's hard to believe, but we're actually seen less snow (to date) than last winter. A couple inches of slush may accumulate Saturday night, possibly mixed with rain or ice. There's another chance of a little snow a week from Friday - temperatures definitely chilling down as we head into mid-December. We'll have enough cold air in place, but can we drum up the moisture? We'll see - but I wouldn't give up on that white Christmas just yet. Image above: Loveland Ski Resort.

 

 

Stay Off The Ice. As we stumble into another potentially anemic winter, with sub-freezing temperatures alternating with thaws, the quality and quantity of ice will be problematic, at least until we get a few (sustained) weeks below freezing. Remind your kids (and spouses) that the ice is far from safe. More details from the Minnesota DNR.

 

 

Sunday Slush? The ECMWF forecast for 12z Sunday (courtesy of WSI) shows the best chance of a fast-moving burst of snow over central and northern Minnesota; a potentially "plowable" accumulation up north. It's still too early to go into specifics, but if you're traveling this weekend you'll want to stay up on the latest forecast.

 

Accurate Flood Forecasting Gets Closer. Flash flooding and river flooding is a short-fuse meteorological challenge. Predicting flooding severity is literally a science within a science. Phys.org has an interesting story on new technology that may help to pinpoint extreme rainfall amounts and subsequent flooding.

 

Tracking Powerful "Atmospheric River" Winter Storms. Water vapor has increased by 4-5%, especially over the tropics, providing more fuel for storms. When weather patterns become locked or "blocked" these streams of concentrated water vapor, dubbed "atmospheric rivers" can focus a fire-hose of moisture on the west coast, as described in this story from NOAA: "...“With satellites, we can see the tell-tale water vapor signature of an incoming atmospheric river over the ocean. However, NOAA’s offshore observing systems do not measure another key factor — strong low-altitude winds,” said Martin Ralph, Ph.D., a research meteorologist and branch chief in NOAA’s Earth System Research Laboratory in Boulder, Colo. “With our new sensors, we’ll be able to measure those winds and more, to understand just how much moisture is moving in, which largely controls how extreme the precipitation inland will become. This information will ensure that meteorologists and emergency managers have additional information to keep the public informed about these potentially destructive storms.” (Image: KQED).

The four coastal observatories will include:

  • A Doppler wind profiling radar, which reveals the speed and direction of winds at several altitudes aloft;
  • A technique for extracting critical information from wind profiler data — the level in the atmosphere where falling snow turns to rain;
  • Global positioning system (GPS) water vapor instruments, which measure the total amount of water vapor above the site; and
  • Standard meteorological instruments (relative humidity, temperature, pressure, rain gauge)."

 

Physicist Happens Upon Rain Data Breakthrough. I love these stories of accidental discoveries and serendipity, but this is how the (sometimes awkward) arc of science works. Here's a snippet from Science Daily: "..."It's not often that you're studying lunar dust and it ends up producing benefits in weather forecasting," said Phil Metzger, a physicist who leads the Granular Mechanics and Regolith Operations Lab, part of the Surface Systems Office at Kennedy. Lane said the additional piece of information would be useful in filling out the complex computer calculations used to determine the current conditions and forecast the weather. "We may be able to refine (computer weather) models to make them more accurate," Lane said. "Weather radar data analysis makes assumptions about raindrop size, so I think this could improve the overall drop size distribution estimates." (Photo courtesy of Mike Hall).

 

Hurricane Warning Definition Modified By NHC In The Wake Of Sandy. NOAA received a fair amount of criticism for dropping hurricane warnings as Sandy's warm core center became absorbed into a massive extra-tropical storm, a classic Nor'easter, but one on a gargantuan scale. Here's an excerpt from Accuweather and Huffington Post: "Following the criticism of the National Hurricane Center's handling of Hurricane Sandy and the non-issuance of hurricane warnings north of North Carolina, it has been decided that the NHC will now have more flexibility in their policy regarding the issuance of advisories. Beginning in 2013, the NHC will have the flexibility to issue multiple advisories on post-tropical cyclones for landfalling systems or close bypassers. According to the NHC, this required a revision of the Hurricane Warning definition, which will now be as follows:

An announcement that sustained winds of 74 mph or higher are expected somewhere within the specified area in association with a tropical, sub-tropical, or post-tropical cyclone. Because hurricane preparedness activities become difficult once winds reach tropical storm force, the warning is issued 36 hours in advance of the anticipated onset of tropical-storm-force winds. The warning can remain in effect when dangerously high water or a combination of dangerously high water and waves continue, even though winds may be less than hurricane force."

UI Researcher Predicts More Intense North Atlantic Tropical Storms. Even if I had the money, I wouldn't dream of buying a beach house on the ocean. No, Minnesota's lakes are looking like a safer bet, long term. Here's an excerpt of an article from The University of Iowa: "Tropical storms that make their way into the North Atlantic, and possibly strike the East Coast of the United States, likely will become more intense during the rest of this century. That’s the prediction of one University of Iowa researcher and his colleague as published in an early online release in the prestigious Journal of Climate, the official publication of the American Meteorological Society. The study is a compilation of results from some of the best available computer models of climate, according to lead author Gabriele Villarini, assistant professor of civil and environmental engineering and assistant research engineer at IIHR-Hydroscience & Engineering, and his colleague Gabriel Vecchi of the National Oceanic and Atmospheric Administration, Princeton, N.J...."

Earth At Night. Here's a look at how these new nighttime images were created, courtesy of NASA: "This new global view of Earth's city lights is a composite assembled from data acquired by the Suomi National Polar-orbiting Partnership (NPP) satellite. The data was acquired over nine days in April 2012 and 13 days in October 2012. It took 312 orbits to get a clear shot of every parcel of Earth's land surface and islands. This new data was then mapped over existing Blue Marble imagery of Earth to provide a realistic view of the planet. The image was made possible by the satellite's "day-night band" of the Visible Infrared Imaging Radiometer Suite, which detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe dim signals such as city lights, gas flares, auroras, wildfires and reflected moonlight..."

 

Global Water Crisis: Too Little, Too Much, Or Lack Of A Plan? Here's a clip from an illuminating story at Yahoo News: "...But superstorm Sandy's deluge and flooding, says Geoff Dabelko, an environmental expert at Ohio University in Athens, is an example of how the term "global water crisis" can be misleading. It tends to imply that there's just one kind of crisis – a water shortage. "The kind of dead-cow-carcass-in-the-desert image that global 'water crisis' evokes is very real for some people," Professor Dabelko says. "But there are so many dimensions." Too much water – whether from flooding, sea level rise, or more extreme storms – can be just as deadly as too little. While the balance between water supplies and the demands of a burgeoning population are further complicated by the effect of climate change on delicate hydrological margins, there are those who say there is enough water, if nations learn to plan for a different future – one in which past abundance is no guide..."

 

Top 5 Weather And Climate Challenges Facing White House. Meteorologist Andrew Freedman has the story from Climate Central; here's an excerpt:

1) Building a More Weather and Climate Resilient Society

Hurricane Sandy, which killed 85 people in the U.S. and caused at least $72 billion in damage in New York and New Jersey alone, highlighted the need to bolster the resilience of coastal cities so that they can withstand the increasing threat posed by the 1-2 punch of global warming-related sea level rise and major storms. Steps that may need to be taken include installing sea walls or storm surge barriers to better protect populated areas, as well as potentially retreating from some vulnerable locations that are almost certain to flood again, given current sea level rise projections. It could also involve reforming the federal flood insurance program, which currently provides incentives to rebuild in vulnerable areas..."

Climate Stories...

 

Forecasting Denial: Why Are TV Weathercasters Ignorning Climate Change? Here's an excerpt of a Rolling Stone story, focused on denial within the TV meteorology community. Why are some TV forecasters still leaning on ideology vs. acknowledging legitimate scientific trends? Here is what I told R.S. environmental writer Jeff Goodell: "...It's not always a matter of ideology, though. Many broadcasters are simply afraid that any talk of global warming will dampen ratings and scare off advertisers. "Talking about climate change is kryptonite for TV meteorologists," says Paul Douglas, a veteran TV weathercaster and reformed climate skeptic who is now the chief meteorologist at Alerts Broadcaster, which specializes in severe weather alerting services. "They tend to abhor anything that might turn viewers off and make it harder for them to renegotiate a big, fat, six-figure salary. By even bringing up the topic, you know you're going to alienate the percentage of the audience who still link global warming with Al Gore and conspiracy theories. Why run into the buzz saw of denial? It's easier to stick to safe topics, like dew point and hot weather survival tips...."


 

Climate Out Of Control. Why are so many TV meteorologists reluctant to talk about climate change during their weather reports? There's a long list of reasons, some legitimate. I was recently interviewed by Jim Poyser (along with TV meteorologists in Orlando) for an article that appeared in Orlando Weekly. Here's an excerpt:

"JP: When did you begin to actually talk about climate change as part of your job as a broadcast meteorologist?

PD: In the late '90s I began including it in my weather statements.

JP: Was anybody else doing it at that time?

PD: No, no. The pervasive feeling at the time was that … if you even mention the term global warming or climate change you will instantly alienate 30 percent of your audience and they will tune out. So, you know, it's kryptonite.

Every day I would get scores of emails like, "Flaming liberal. You crazy crackpot. Why are you buying into this Al Gore conspiracy? You're going to cripple our economy." It is the equivalent of sticking your finger in the electrical socket. Most of us are conditioned to avoid pain, to avoid controversy. Everybody on television wants to be loved and your contract – whether you're renewed – really depends on your ability to attract an audience. Just by reporting on this you know that you're alienating people with a certain ideology...."

CNN Gives Climate Change Denial A Platform. I watched this spectacle Tuesday evening. Bill Nye (the science guy) did an admirable job, but why they didn't have a climate scientist to talk about the trends is baffling. The media wants "balance"? Then CNN should have had a panel of 98 peer-reviewed scientists debating 2 fossil-fuel industry shills. That would have been journalistically balanced. But a TV food-fight makes for better ratings, right? Media Matters has the story; here's an excerpt: "...If the role of the media is to inform its audience, anchors must recognize how people are informed and misinformed. When people are repeatedly exposed to a myth, it becomes more familiar and they are more likely to believe it. By giving Morano a platform to claim that average temperatures have not warmed in nearly 20 years, Morgan enabled him to familiarize CNN's audience with climate myths. It's not surprising that Morano seized the opportunity to spread confusion about climate change. His website is sponsored by the Committee for a Constructive Tomorrow, an organization that has received funding from oil companies. As New York Times reporter Andrew Revkin explained, "industry-funded groups have used the media's tradition of quoting people with competing views to convey a state of confusion even as consensus on warming has built." Morano has promoted extreme attacks on climate scientists and those that accept global warming. His website often publishes the email addresses of scientists, leading to a barrage of hate mail, and he defended a billboard campaign comparing those who accept climate science to the Unabomber, saying it was "edgy."

 

Bill Kurtis On Global Warming. One of the (few) good things to come out of my brief stint in Chicago was working with Bill Kurtis, a legendary anchor, reporter and award-winning journalist. And a decent human being, the kind of guy you'd want to have a beer with. Here is his take on climate change, an excerpt of a recent Op-Ed at The Chicago Sun Times: "...A small number of skeptics have managed to take the adrenaline out of the global warming movement; and by creating the impression that there are actually two sides to the issue, they have stalled efforts to do something about it. I’ve been producing documentaries on global warming for 20 years and have seen the early warnings of extreme weather events come true. Predictions of stronger hurricanes now have names — Katrina and Sandy. Greater forest fires recall the Colorado Springs fire last June. More droughts — this year’s drought in the Midwest is the worst in more than 50 years. The prediction that glaciers will be gone from Glacier National Park has been moved up by 10 years to 2020, the same year it’s predicted the Arctic Sea will be ice-free in the summer..."

 

Treat Climate Change As A "Waste Management Problem". Spoken like a true engineer, and absolutely true. But we've never had a waste management problem of this scale and severity. Everything we do, everywhere we go, all things manufactured and consumed hinges on carbon, the extraction and burning of fossil fuels. But maybe this guy is onto something. Here's an excerpt from Consumer Energy Report: "... The debate for me is over because I believe we have the technology available to us today to develop hydrocarbons and to use those hydrocarbons in ways in which we can use them fully and clean up after ourselves; with respect to physical waste, liquid waste, and gaseous waste. So if we approach the issue of global warming/climate change as an issue of waste management – which I would prefer to do – rather than some kind of global crisis which remains undefined and unresolved. Let’s deal with what we know how to deal with. We know how to deal with waste..."

 

How Has Climate Change Affected Your Winter Sports? What winter sports? Oh yeah - it's meteorological winter out there, at least on paper. Lately it seems like Minnesotans experience all or nothing winters. Either we get buried under 70" or more of snow (once every 4 or 5 winters, on average) or we see dribs and drabs of snow (last winter comes to mind). Here's a clip from The PBS NewsHour: "The winter of 2011 was so unusually warm and dry, it left some ski resorts struggling to create enough powder to sustain their season. Winter sports enthusiasts are now facing the possibility of another warm, dry winter, which means more snow machines and fewer skiers, snowboarders and outdoor skaters. We want to hear from you -- how have the changing seasons affected your favorite winter pastimes? Are you a skier, snowboarder or ice-skater who has had to travel farther to find snow and ice? Have fewer snow days meant less time sledding? Have winter tournaments or outdoor games been cancelled or rescheduled due to unseasonably warm weather?"

U.S. Price Tag For Allergies Will Rise Because Of Climate Change. Scientific American has the story; here's an excerpt: "Researchers are probing the health and economic fallout from this year's record allergy season to understand how warming weather and shifting rainfall may lead to more widespread and costlier allergy problems in the future. Already, doctors are seeing climate change alter how allergens disperse. "It played out in the form of the duration of the pollen season," said Leonard Bielory, an attending physician and allergist at the Robert Wood Johnson University Hospital and a professor at Rutgers University's Center for Environmental Prediction..."

Why Seeing Is Believing - Usually - When It Comes To Climate Change. Wait. Climate change requires connecting the dots and a concept known as "thinking"? Uh oh. We're in trouble. Here's an excerpt from an interesting article at Time Magazine:

"One possible explanation for these low levels of belief certainty and perceptions of the threat as distant as that of climate change is difficult to perceive directly; `climate’ itself is a statistical abstraction, even though its impacts can be quite tangible. Current theories of cognitive science suggest that learning about abstractions requires analytical information processing, which involves cognitive effort...a scarce commodity, which people expend sparingly. Both low motivation to think about climate change and low ability to comprehend scientific information can impede people’s processing of the charts, graphs and models in the climate scientist’s toolkit.

In other words, climate change is hard to really see in one’s daily life, and understanding it requires “analytic information processing”—otherwise known as thinking. That’s not something people have a lot of time, inclination (and perhaps ability) to do..."
