Veteran's Day Cold Front (50s next weekend; even colder next week - unfolding horror left behind by "Haiyan")

Posted by: Paul Douglas Updated: November 11, 2013 - 8:38 AM

Canadian Appetizer

Yesterday was another meteorological disconnect, gazing out at a supernaturally-green lawn in need of one last mowing - long shadows cast by a feeble sun barely clearing the treetops. A fleeting ration of blue sky.

The sun is as high as it was in late January; longer nights and snow on the ground brewing up colder colds across Canada. A fresh burst of wind chill will chase away any visions of Indian Summer over the next 48 hours; highs stuck in the 20s today and Tuesday with a wind chill slipping into single digits. Cold enough.

40s return late week; a shot at low 50s next weekend with a little rain Saturday night and early Sunday.

And then things get more interesting. ECMWF (European) model data shows rain changing to snow 1 week from today. Some accumulation is possible as the leading edge of an "arctic gusher" sweeps southward. Think of today as a cold weather appetizer. The main course is 7-10 days away.

It's premature to contemplate snowfall amounts - although I don't envision a major dumping you might just want to plant your driveway stakes within the next week or so.

The pattern favors cold east and mild west. Autumn is finally succumbing to winter.

Happy Veterans Day. Go out of your way to thank someone who has served or is serving. We owe these men and women nothing less than our freedom.


Anniversary Of The Armistice Day Blizzard. November 11-12, 1940 brought extreme changes to Minnesota; large temperature contrasts whipping up a sudden (unpredicted) blizzard. Could the same thing happen today, in spite of computer models and Doppler radar? I'd like to think not (if anything it would probably be over-hyped) but this storm was an abject lesson in humility; a lesson we should never forget. Wikipedia has a good overview of this historic storm: "The morning of 11 November 1940 brought with it unseasonably high temperatures. By early afternoon temperatures had warmed in lower to middle 60s °F (18 °C) over most of the affected region. However, as the day wore on conditions quickly deteriorated. Temperatures dropped sharply, winds picked up, and rain, followed by sleet, and then snow began to fall. An intense low pressure system had tracked from the southern plains northeastward into western Wisconsin, pulling Gulf of Mexico moisture up from the south and pulling down a cold arctic air mass from the north. The result was a raging blizzard that would last into the next day. Snowfalls of up to 27 inches (69 cm), winds of 50 to 80 mph (80–130 km/h), 20-foot (6.1 m) snow drifts, and 50-degree Fahrenheit (30 °C) temperature drops were common over parts of the states of Nebraska, South Dakota, Iowa, Minnesota, Wisconsin and Michigan. In Minnesota, 27 inches (69 cm) of snow fell at Collegeville, and the Twin Cities recorded 16 inches (41 cm). Record low pressures were recorded in La Crosse, Wisconsin and Duluth, Minnesota. Transportation and communications were crippled, which exacerbated finding the dead and injured. The Armistice Day Blizzard ranks #2 in Minnesota's list of top-5 weather events of the 20th century..."


Serious Ups And Downs. Here is ECMWF Guidance looking out 8 days, showing temperatures holding in the 20s today and Tuesday as wind chill values sink into single digits at times. At least the sun should be out later today and all day Tuesday. We warm into the 40s during the latter half of the week, 50s over the weekend with light rain or showers Saturday night into early Sunday, then a period of rain changing to snow 1 week from today as MUCH colder air approaches. Temperatures dip into the teens by Tuesday of next week. Graph: Weatherspark.

Philippines Typhoon Haiyan: "It Was Like A Tsunami". Of course they're refering to the storm surge, a dome of water preceding the eye of this record storm, possibly 15 feet or more above sea level. Z News has more details; here's an excerpt: "Tacloban: The fierce storm that ravaged Philippines on Friday inflicted massive destruction and wreaked havoc in the country with many likening it to tsunami as most of the deaths were caused by the towering sea waves. A top UN disaster management official recalled Indian Ocean tsunami of 2004 while describing the situation. “The last time I saw something of this scale was in the aftermath of the Indian Ocean tsunami", Sebastian Rhodes Stampa, the head of United Nations disaster assessment team which visited the area on Saturday, said in his report as cited by the New York Times. “This is destruction on a massive scale. There are cars thrown like tumbleweed,” he added.Philippines Interior Secretary Mar Roxas described the situation as "horrific" adn said that the level of destruction called for an overwhelming level of relief and rescue operations..."

Scale Of Damage Caused By Super Typhoon Emerges. Here's a video clip and excerpt from ITV News: "...Experienced aid workers are saying they haven't seen anything like it since the December 2004 Asian Tsunami, and that's not a comparison you make lightly. The US military is standing by by ready to give assistance. I was speaking to a colonel in the US Marines today. He had been up with the air force, surveying the worst affected areas. The government of the Philippines has now accepted the UN offer of international assistance..."


858 mb. Data suggests that the central pressure of Super Typhoon Haiyan may have dropped to 858 mb before reaching the Philippines, an unimaginable 25.33" of mercury. That would make Haiyan the strongest storm ever observed on the face of the Earth. This is satellite-derived and not yet confirmed.

CBC News in Canada estimates as many as 10,000 dead just in Tacloban City, Philippines.


Super Typhoon Haiyan: One Of The Word's Most Powerful Storms In History From Space. Here's a reminder of how vitally important weather satellites are across the board, but especially with hurricane tracking and intensity estimates. The USA is the only nation that flies planes (and probes) into hurricanes to get a more accurate 3-D picture of a storm. Meteorologist Jason Samenow has more details at The Capital Weather Gang: "Over the last three days, satellite imagery has provided astonishing views of the storm’s structure. Many meteorologists, myself included, have remarked that they’ve never seen a storm with such an impressive presentation. From its unmistakably clear eye (episodically blurred by small swirls or mesovortices spinning inside it), the towering thunderstorms surrounding it, and its impeccable symmetry – it is a textbook, “perfect” tropical cyclone..."

Should There Be A Category 6 For Hurricanes? Greg Laden brings up the pros and cons in a post at scienceblogs.com; here's a clip: "...There is resistance to this proposal that comes from two mostly distinct places. One is the community of those who deny the science of climate change, or climate change itself, or science itself. Their motivation is to not allow the so called “alarmists” (those who are alarmed at the changes happening on our planet) to have a tool to point out that severe weather can be very severe indeed. The other is the subset of meteorologists who are actually correct, in a way, when they point out that the Saffir Simpson scale, the scale with the five categories, can’t be extended because of the way it is built, but who are very incorrect, I think, when they point out that extending the scale would damage the most important available tool for scaring people into running away (or staying indoors)..."


Scientists Develop A New Way Of Classifying Hurricanes. There are probably more effective ways to communicate the potential damage of a given hurricane, going beyond Saffir Simpson. Here's an excerpt of a relevant and still-timely May 7, 2013 post from Climate Central: "...Now, a new study, published in the journal Monthly Weather Review by scientists from Florida State University, proposes a new metric that aims to complement Saffir-Simpson and other recently developed scales by taking into account a storm's intensity, duration and size. The metric, know as "Track Integrated Kinetic Energy", or TIKE, builds from an existing measure of storm integrated kinetic energy (IKE), which was developed in 2007..." (Image: NOAA).


After Typhoon, A Look At Powerful U.S. Storms. Here's a good recap of America's most extreme hurricanes, courtesy of AP and seattlepi.com: "A typhoon that slammed the Philippines is among the strongest on record with sustained winds of nearly 150 mph when it made landfall, and the destruction it caused rivals that of some of the most powerful hurricanes to strike the U.S. mainland. A hurricane's intensity is typically gauged by its barometric pressure. Below are the five most intense hurricanes on record to strike the U.S. mainland, ranked by minimum pressure at landfall, according to the National Hurricane Center in Miami. Forecasters say the accuracy of wind speeds is somewhat uncertain for some historical hurricanes because of limits on technology at the time..."

The Hurricane Center says no wind measurements were available from the core of this small but “vicious” hurricane, which was a Category 5 storm when it reached the Florida Keys. But a pressure measurement taken at Long Key, Fla., makes it the most intense hurricane ever to make landfall on the U.S. mainland. It was blamed for 408 deaths and caused an estimated $6 million (1935 dollars) in damage." Photo: Uncredited, AP.


Tranquil Year For Tornadoes. 2013 has been the second-quietest year for tornadoes since 1990, according to NOAA SPC. USA Today has a good recap; here's the introduction: "Hurricanes have been on holiday this year, and so too have their ferocious cousins, tornadoes. The USA is enjoying its second-consecutive below-average tornado season, and one of the calmest years for tornadoes in more than two decades, according to data from the Storm Prediction Center in Norman, Okla. "It's been a near-record quiet year, especially with respect to strong to violent tornadoes," said warning coordination meteorologist Greg Carbin of the prediction center..."

China's Massive Pollution Problem. The Week has an update; here's the intro: "How bad is China's smog? Sixteen of the world's 20 most polluted cities are in China. The air in some cities there is so bad that, at times, visibility drops to 30 feet, traffic slows to a crawl, and nearly everyone wears masks over their noses and mouths. In Harbin, a city of 11 million people, government officials recently shut down roads, schools, and the airport when air pollution levels hit 40 times the safe limit set by the World Health Organization (WHO). During the "airpocalypse" in Beijing earlier this year, the density of small, lung-penetrating particles reached 993 micrograms per cubic meter — a concentration normally not seen outside of forest fires. The U.S. Environmental Protection Agency (EPA) considers anything above 300 dangerous, and maxes out its scale at 500..."

Visibility shrank to less than half a football field and small-particle pollution soared to a record 40 times higher than an international safety standard in the northern Chinese city as the region entered its high-smog season."

Remembering The "White Hurricane" Of Mid-November, 1913. Here's a great recap of a wild storm that whipped up 90-mph winds and 30-40 foot seas on the Great Lakes in 1913, courtesy of the Detroit office of the National Weather Service: "During the infamous “White Hurricane” of November 1913, intense lake-effect snow occurred downwind of the Great Lakes as cold, arctic air moved over the relatively warm lake water. The wind and snow combined to cause whiteout conditions, paralyzing many cities across the Great Lakes Region. Port Huron, Mich., and Cleveland, Ohio, were two of the hardest-hit cities, experiencing both heavy snowfall and tremendous snow drifts. Cleveland broke its 24-hour snowfall record, with 17.4 inches in one day and a three-day total of 22.2 inches. High winds caused extensive power outages across the Great Lakes, effectively cutting off communication via telephone and telegraph."


Fear Of The Dark. How real are the risks of a major failure of the power grid? The New York Times takes a look - here's an excerpt: "...Energy in general is something people like to worry about, said Mr. Apt, and grid failure is the latest target of that anxiety. “It echoes the ‘peak oil’ theme,” he said, referring to the alarmist concern, especially before the advent of fracking, that oil supplies had peaked and were about to shrink, with catastrophic results. The idea of a sustained blackout resonates in the public’s mind, agreed David Ropeik, an expert on risk perception, particularly because it could come from either cyberattack, physical attack by terrorists or even Mother Nature as a side effect of solar flares. “It is one of those low-probability, high-consequence events that every once in awhile scares the bejesus out of us,” he said..."

South Florida Faces Ominous Prospects From Rising Waters. The New York Times has the story - here's a clip: "...Much of Florida’s 1,197-mile coastline is only a few feet above the current sea level, and billions of dollars’ worth of buildings, roads and other infrastructure lies on highly porous limestone that leaches water like a sponge. But while officials here and in other coastal cities, many of whom attended a two-day conference on climate change last week in Fort Lauderdale, have begun to address the problem, the issue has gotten little traction among state legislators in Tallahassee. The issue appears to be similarly opaque to segments of the community — business, real estate, tourism — that have a vested interest in protecting South Florida’s bustling economy..."


Vermont's Bill McKibbon Finds Climate Change Taking A Toll - On Him. I've met Bill - he's passionate, relentless and tenacious, and he keeps up an almost supernatural pace. The Rutland Herald has the story - here's a clip: "In his travels as an environmental author and activist, Ripton resident Bill McKibben is used to receiving climate-change questions from skeptics who sound like Stephen Colbert, the sly television satirist who once inquired, “Did you come down from Vermont in some car powered by self-righteousness?” But the author of the first book about global warming written for a general audience was surprised recently by the mother of one of his daughter’s former schoolmates. Standing outside a local library, the woman was distributing fliers accusing the crusader who has jetted to every continent (“once I hit four of them in six days”) of having too big a carbon footprint..."

Super Typhoon Haiyan: A Hint Of What's To Come? Climate Central meteorologist Andrew Freedman takes a look at how warming oceans may be impacting the intensity of hurricanes and typhoons; here's a clip: "Super Typhoon Haiyan was one of the most intense tropical cyclones at landfall on record when it struck the Philippines on Nov. 7. Its maximum sustained winds at landfall were pegged at 195 mph with gusts above 220 mph. Some meteorologists even proclaimed it to be the strongest tropical cyclone at landfall in recorded history. Haiyan’s strength and the duration of its Category 5 intensity — the storm remained at peak Category 5 intensity for an incredible 48 straight hours — raises the question of whether manmade global warming tipped the odds in favor of such an extreme storm. After all, the global atmosphere contains 4 percent more water vapor than there was in the 1970s and global air and sea surface temperatures are higher now than they used to be, due in large part to manmade global warming as well as natural climate variability. These changes would, in theory at least, lead to stronger and wetter storms..."

More information on the image above provided by NOAA:

"The intensification of Super Typhoon Haiyan is being fueled by "ideal" environmental conditions - namely low wind shear and warm ocean temperatures. Maximum sustained winds are currently at 195 mph, well above the Category 5 classification used for Atlantic and East Pacific hurricanes. Plotted here is the average Tropical Cyclone Heat Potential product for October 28 - November 3, 2013, taken directly from NOAA View. This dataset, developed byNOAA/AOML, shows the total amount of heat energy available for the storm to absorb, not just on the surface, but integrated through the water column. Deeper, warmer pools of water are colored purple, though any region colored from pink to purple has sufficient energy to fuel storm intensification. The dotted line represents the best-track and forecast data as of 16:00 UTC on November 7, 2013."


"Last" Arctic Region Succumbing To Global Warming. Here's the intro to a story at Blue and Green Tomorrow: "Researchers from Ontario universities say that the lakes of the Hudson Bay Lowlands in north-east Canada, one of the last areas to hold out against global warming trends, are showing signs of sudden change. Their study, published in the journal Proceedings of the Royal Society B, notes that the sub-Arctic region had maintained stable, cool temperatures for hundreds of years until the mid-1990s, thanks to sea ice on Hudson Bay – the largest northern inland sea – that naturally cooled the waters. However, average air temperatures in the area have also risen dramatically – going from around 0C in the mid-1990s to 3C by the end of the 2000s in the shoreline town of Churchill, Manitoba. By studying long-dead algae from the lakebeds off the Hudson Bay shoreline, the scientists found that the waters have warmed at an extraordinary rate and magnitude over the last two decades..."

The guide, under the guise of being "Ranger Brad" says, "Today we're taking some kids on the best field trip they could wish for." He then shows them some pictures of leaves, while the camera pans around the bus at bored, tired, yawning kids. Then, surprise! He reveals they are not going on a natural science field trip at all, but to... Toys "R" Us! Celebration! Confetti littering the ground as the kids run from the bus into the store! Free wild rumpus in the store playing with whatever they want. Hooray!.."
