Thawing Out (more on freak Saturday night tornadoes; Thanksgiving Travel Preview; $50 billion in estimated damage from Sandy in New York City area)

Posted by: Paul Douglas Updated: November 12, 2012 - 9:32 PM

 

Now Or Never. I just got home from a 2 week Panama Canal cruise with my 82 year old father, my wife and some good friends. It's something we've been talking about for a few years, and so we took the plunge and reserved the 14 day cruise on Princess, leaving from L.A., stopping in Cabo, Nicaragua and Costa Rica before pushing thru the canal on Election Day (which took about 7 hours). It was a once in a lifetime experience, and I wanted to do it now, with my father in relatively good health. My goal is to be able to look back and not have serious regrets ("could have, should have, would have.."). I think I spent $500 on satellite internet WIFI to keep tabs on Sandy and last week's Nor'easter for our corporate clients - talk about lousy timing. But nobody got sick or injured. With frequent visits to the buffet line I fear I may be showing up on Doppler for some time to come. My thanks to meteorologist Todd Nelson for filling in while I was gone. PS: I highly recommend seeing The Big Ditch. It's something you should do once in your life, if possible.

 

1" of rain the Wednesday before Thanksgiving with showers tapering, possibly ending as flurries Thanksgiving Day? Long-range guidance is hinting at mostly rain from next week's storm, a cold rain at that. On the other hand, the (often superior) ECMWF keeps us dry most of next week with highs in the 50s next Wednesday. At this point I'm leaning toward this (drier/milder) solution

 

Looks Like Snow. As of yesterday 31.5% of the USA had some snow on the ground, according to NOAA, up from 2.1% on October 12, 2012. I'm always amazed what a coating of snow can do during rush hour, when temperatures are in the teens and low 20s (cold enough for the salt/sand mix MnDOT uses not to work very well). Rush hour yesterday was a disaster - today should be better.

 

November 16, 1931: latest tornado ever observed in Minnesota, east of Maple Plains. Details here.

4 tornadoes reported in Minnesota during the month of November (2 of them were Saturday night). Details below.

 

 

Weather Whiplash

I may be showing up on Doppler the next few weeks. I just got back from a two week Panama Canal cruise with my wife and 82 year old dad - studying tropical weather - and the buffet table.

Burp.

69 F on Saturday, followed by 20s Sunday and a howling wind of Siberian origin? This extreme cold front whipped up a few small EF-0 tornadoes Saturday night near Burnsville & Eagan. November twisters are exceedingly rare; with Saturday's outbreak there have been only 4 tornadoes in November in modern-day records.

SPC had parts of southern Minnesota in a slight risk, but there were no watches or warnings in effect when severe storms spun up these small, brief tornadoes. What happened? The greater the contrast in temperature the stronger the winds have to blow; and there was just enough wind shear aloft to spin up small, brief, 75-80 mph tornadoes

With our expanding autumns maybe we shouldn't be too surprised. Moral of the story: never let your guard down - when skies turn threatening head for the basement, even in November.

Monday's icy coating of snow melts today; highs in the 40s this week - near 50 (above!) next week. No big storms brewing here into Thanksgiving, the way the maps are setting up. The biggest, sloppiest storms continue to detour well south/east of Minnesota and Wisconsin.

Yet another Nor'easter may cause (relatively minor) coastal flooding along the east coast next week. Folks out east just can't catch a break.

 

$50 billion in estimated damage in the New York City area alone from Sandy. Details from The New York Times.

 

Hurricane Sandy And The Disaster Preparedness Economy. The hottest gift for the holidays out east? Emergency generators. I'm not kidding. Forget jewelry and clothing - people want some assurance the power will stay on the next time a wild storm strikes. Here's an excerpt from The New York Times: "FOLKS here don’t wish disaster on their fellow Americans. They didn’t pray for Hurricane Sandy to come grinding up the East Coast, tearing lives apart and plunging millions into darkness. But the fact is, disasters are good business in Waukesha. And, lately, there have been a lot of disasters. This Milwaukee suburb, once known for its curative spring waters and, more recently, for being a Republican stronghold in a state that President Obama won on Election Day, happens to be the home of one of the largest makers of residential generators in the country. So when the lights go out in New York — or on the storm-savaged Jersey Shore or in tornado-hit Missouri or wherever — the orders come pouring in like a tidal surge..."

Sandy Victims Face Insurance Nightmare. CNN Money has the story - here's an excerpt: "When Roman and Marianna Bediner's Staten Island, N.Y., home was clobbered by Superstorm Sandy they took some comfort in knowing that it was insured. But a few days later, when they learned that their coverage would pay for only a fraction of the $75,000 to $100,000 needed to put the house back together again, that feeling evaporated. During the storm, Roman said the waters of Lower New York Bay rose by close to 11 feet, destroying all the walls, floors and ceilings -- not to mention the furniture and carpets -- on the first floor of his home. When the area flooded, the sewers backed up, filling the Bediners' ground floor with water that contained raw sewage and contaminating the home..."

Hurricane Sandy Damage Amplified By Breakneck Development Of Coast. Some unpleasant trends are converging. At the same time storms are becoming more intense (and sea level is rising, by at least a foot since 1900 in the New York City area) coastal development has exploded. Who doesn't want to live near the water? Minnesota lakes are quite tame compared to what can nappen when a hurricane storm surge coincides with high tide and a full moon. More from Huffington Post: "...Given the size and power of the storm, much of the damage from the surge was inevitable. But perhaps not all. Some of the damage along low-lying coastal areas was the result of years of poor land-use decisions and the more immediate neglect of emergency preparations as Sandy gathered force, according to experts and a review of government data and independent studies. Authorities in New York and New Jersey simply allowed heavy development of at-risk coastal areas to continue largely unabated in recent decades, even as the potential for a massive storm surge in the region became increasingly clear. In the end, a pell-mell, decades-long rush to throw up housing and businesses along fragile and vulnerable coastlines trumped commonsense concerns about the wisdom of placing hundreds of thousands of closely huddled people in the path of potential cataclysms..."

"Ask Paul". Weather-related Q&A:

Hi Paul,

Read you all the time.  Been a follower since 1988.

I’m very confused how a tornado could spin up, touchdown in my back yard with absolutely no warning.  In fact, I had just concluded watching a local weather forecast about 10:20 on Sat. night and there was no mention of strong wind, severe weather, nothing.  I just watched a rebroadcast of the weather segment again in case I missed something.  There were no sirens in Burnsville. 

Everyone likes to pounce on the weathercasters when they miss a forecast by a few degrees or ‘scattered showers’ hover over their picnic, but this is serious stuff.  How can this tornado have possibly been missed by everyone on your field?

Regards, Mike Svec

 

Mike - I was on a cruise ship off the coast of Florida Saturday night (I know, no excuse), but I'm trying to piece together what happened. SPC had a slight risk into southern Minnesota Saturday, but you're right: no watches or warnings were in effect when the line of strong/severe storms arrived. Dew points were in the 40s and low 50s, so moisture was somewhat limited, but with a 40 degree temperature drop across the cold front there was ample wind shear to spin up small, brief tornadoes (in 20-20 hindsight, of course). The situation was marginal at best for tornadoes. And Doppler radar works best on the big, supercell thunderstorms, not the small storms that swept thru Saturday night. The resulting twisters were too small and brief to create a noticeable "couplet" on Doppler.

Here's our new reality: technology is good, leaps and bounds better than the radars we were using back in the 70s and 80s. But it's not perfect, and never will be. There will be (rare) occasions where tornadoes still spin up, with little or no warning. I want to believe we'll catch the big (EF-2+) tornadoes, but the little ones? Very difficult - they literally get lost in the sauce. When winds pick up suddenly you head to the basement, or an interior room, even if it's mid-November.

KSTP.com has a good article explaining how the rapid forward speed of Saturday's squall line also made it extra- tough for meteorologists at the local NWS to isolate the tornado-producing cells. It's not like a May outbreak, where just about anyone with a pulse can pick out a tornadic cell, either in reflectivity or radial velocity mode. Finding an EF-0 is the meteorological equivalent of finding the proverbial needle in a haystack; one that's clipping along at 40-50 mph.

The Twin Cities NWS has more on the November 10 tornadoes in the south metro here. Some of the photos from near Burnsville and Eagan are below.

European Scientist: How We Improved Our Forecast Model, And How It's Reliant On U.S. Satellite Data. Eric Berger at The Houston Chronicle has a good story about how the European (ECMWF) model is, in many cases, better than the U.S. models. There's a good reason - how the model is initialized, with new data fed into the model in real-time, as it arrives, including satellite data from U.S. weather satellites. Here's an excerpt: "...Physics is essential. In 2007 we made big changes to the model’s physics, in particular the convection and clouds. This had quite a large impact on our skill with tropical cyclones. Another essential element is the way we use observations. This is what we call data assimilation, the way we initialize our models. This is an area where I think we are leading. The way we initialize our model using observations is probably quite advanced compared to other centers. We make a very large use of satellite data in particular, and particularly satellites from the United States. We have a strong collaboration with NOAA. To have these initial conditions accurate, and not accurate only in the vicinity of the hurricane, or what is going to become a hurricane, but the large scale flow around the hurricane is very important as well...."

Thanksgiving Day Weather Preview. Don't bet the farm based on a 9 day outlook, but the GFS is suggesting a significant storm pushing across the Midwest and Great Lakes next Wednesday. In fact the GFS model prints out over 1" of rain the Wednesday before Thanksgiving in the Twin Cities - probably rain. I could see rain showers ending as snow showers or flurries on Thanksgiving Day. Stay tuned.

 

Reality Check - We're Still In A Drought. The ECMWF keeps us dry next week, highs in the 50s next Wednesday with no storms nearby. Based on the recent track record of the European model I'm inclined to discount the (soggy) GFS forecast above and go with the milder, drier ECMWF solution. Map above valid 6 pm next Wednesday, courtesy of WSI.

 

27 F. high on Monday in the Twin Cities. Wind chill readings dipped into the low teens at times.

43 F. average high for November 12.

64 F. high on November 12, 2011.

2/10ths of an inch of snow fell at MSP.

 

Instant Winter. What happened? 69 F. on Saturday, 20s yesterday and today. Like a cold slap across the face. Or turning off a light switch. Nothing like easing into winter. Monday highs ranged from 20 at Alexandria to 25 St. Cloud, 27 Twin Cities and 28 Redwood Falls, nearly 20 degrees colder than average. How I long for average...

** photo of bus accident on I-35 Monday morning courtesy of MnDOT. More details on the icy start to Veterans Day:

  • Windswept snow made for dicey driving conditions Monday morning around the Twin Cities area, including on a Minneapolis interstate, where a Metro Transit bus spun out late in the rush hour.
  • The Route 114 bus had blocked all but the far left lane of southbound Interstate 35W between 26th and Lake streets, until its removal about 9:10, transit spokesman John Siqveland said. No injuries were reported. Only the driver was aboard the articulated bus.
  • The bus jammed up traffic for about an hour.
  • Fortunately for commuters, Monday is a holiday for many government workers in observance of Veterans Day. That means less traffic on the slick freeways and main thoroughfares. Even so, the bus mishap was one of several for motorists, who are getting their first reminder that wintry weather is drawing near.

 

Climate Stories....

 

Former UN Official Says Climate Report Will Shock Nations Into Action. The story from The Sydney Morning Herald; here's an excerpt: "THE next United Nations climate report will ''scare the wits out of everyone'' and should provide the impetus needed for the world to finally sign an agreement to tackle global warming, the former head of the UN negotiations said. Yvo de Boer, the UN climate chief during the 2009 Copenhagen climate change talks, said his conversations with scientists working on the next report of the Intergovernmental Panel on Climate Change suggested the findings would be shocking. "That report is going to scare the wits out of everyone,'' Mr de Boer said in the only scheduled interview of his visit to Australia. "I'm confident those scientific findings will create new political momentum.''

 

 

Lance Armstrong And Superstorm Sandy Were Both Doped. Here's an excerpt of an article that caught my eye from scholarsandrogues.com: "If you’re a cycling enthusiast, you’re no doubt aware that Lance Armstrong was recently stripped of all of his Tour de France wins because the U.S. Anti-Doping Agency found evidence of doping. While there are some questions that remain unanswered in the case and there are certainly reasonable criticisms that can be levied against the USADA’s investigation, the scientific evidence appears to be overwhelming. But I’m not here to talk about Lance Armstrong. Instead, there’s another example where the scientific evidence of doping is overwhelming even though there are a few reasonable criticisms and a few unanswered questions – the doping of Superstorm Sandy by the performance enhancer known as industrial climate disruption (aka global warming or climate change)..."
