“March-ember” for much of USA

16 Dec 2012, 9:02 am






Saturday Snowfall across Minnesota. Although just about all rain in the Twin Cities, Brainerd picked up a 2-4″ icy mix of freezing rain followed by snow. Over 5″ of new snow caked International Falls. More details from NOAA here.




328 Days without a Sub-Zero Temperature in Rochester MN – All Time Record in Jeopardy. Rochester International Airport has not fallen below zero since January 21 2012 -12 degrees. This 328 day stretch ties a similar stretch in 1999 January 26-December 19 for the third longest stretch of days without falling below zero. This current streak is just 5 days from the record of 333 days set back in 1987 January 27 through December 25. With no sub-zero temperatures in forecast for next week, this record will likely bebroken on Thursday, December 20th. Source: NOAA.






Big Snow for Chicago? Not Here.A very significant storm spins up later this week, along the leading edge of a colder surge. Heavy snow is possible from the Quad Cities to Madison, Milwaukee and Chicago by Thursday, a warm rain (and a few severe T-storms) pushing into the eastern seaboard? Like something out of March.

Christmas Slush. It’s pretty far out on the horizon, but just for laughs and giggles I thought I’d include the outlook for Christmas Morning, showing a possible severe T-storm outbreak from Dallas and Houston to Memphis, with a storm winding up over the Upper Midwest, possibly a rain/snow mix for much of Minnesota, with heavier snow (only) for the Dakotas – a rather turbulent map,and if it verifies, weather will almost certainly be a factor for Christmas travel. 12z December 25 ECMWF (European) map from WSI.






2012: Warmest Year On Record for the Twin Cities? Here’s an excerpt of an e-mail I received from Minnesota State Climatologist Greg Spoden: “As I’m sure you are aware, Twin Cities temperatures in 2012 have been pervasively warm. March 2012 was the warmest March on record by a large margin. July 2012 was the second warmest July (and the second warmest of any month) of the modern record. October was the only below-normal temperatures month of the year. As the calendar year comes to a close, there exists the potential to break the record for the warmest annual average temperature found in the modern Twin Cities climate data set (1872-2012). Should the December monthly average temperature finish above 24.0 degrees, a new calendar year average temperature record will be established. This will require that the monthly average temperature exceeds the December normal average temperatures (19.7 degrees) by more than 4.3 degrees. Given December temperatures reported thus far, along with the outlooks for the second half of December, such a scenario appears to be plausible.”

2012: Probably The Warmest Year In Recorded U.S. History. Here are a few bullet points from NOAA NCDC:

  • The January-November period was the warmest first 11 months of any year on record for the contiguous United States. The national temperature of 57.1°F was 3.3°F above the 20th century average, and 1.0°F above the previous record warm January-November of 1934. During the 11-month period, 18 states were record warm and an additional 24 states were top ten warm.


  • It appears virtually certain that 2012 will surpass the current record (1998, 54.3°F) as the warmest year for the nation. December 2012 temperatures would need to be more than 1.0°F colder than the coldest December (1983) for 2012 to not break the record.


Unstable Ice. I can’t stress enough to outdoor enthusiasts of all ages that ice in and around the Twin Cities, even St. Cloud, is still not even close to being “safe”. Mille Lacs, Gull and the Whitefish Chain is mostly ice-covered, but you should absolutely check with local authorities before dragging your ice house out. NASA’s 1,000 meter MODIS satellite still showed open water on metro lakes yesterday, extending south to Mankato and Lake Pepin. Be careful out there.

Slight Shrinkage. NOAA data shows snow on the ground over 35.6% of the lower 48 states, compared with 17 % of the same area a month ago, on November 13, 2012. Many northern tier cities will see a white Christmas. The rest of the USA? Not so much.

The Weather Cliff? New Study Warns Of Sequestration Impacts To NASA, NOAA Programs. Here’s an excerpt from a post at the Second to None web site: “A new economic impact analysis concludes that over 20,000 NASA contractor jobs and over 2,500 NOAA jobs related to weather satellites could be lost in 2013 if the Budget Control Act’s sequestration mandate takes effect on January 2, 2013. “This report demonstrates that the biggest single threat to our space programs’ continued success are arbitrary and capricious budget cuts,” said AIA President and CEO Marion C. Blakey. “NASA and NOAA are responsible for cutting edge activities that expand the boundaries of knowledge and discovery, lead to economic innovation and save lives.  We can’t afford not to invest in these sources of American scientific and technological greatness…”

Editorial: Why No Hurricane Warnings For Sandy? Here’s a portion of an Op-Ed from USA Today: “When Sandy clobbered the Northeast on Oct. 29, it carried torrential rains, record flooding — and hurricane-force winds. Gusts reached 90 mph in New York and New Jersey, 86 mph in Rhode Island, 85 mph in Connecticut, 83 mph in Massachusetts and 81 mph in Pennsylvania. Despite these clear-cut Category 1 conditions, however, no hurricane watches or warnings were posted in any of those states.

OPPOSING VIEW: Our warnings were clear and effective

Why not? In the six weeks since Sandy struck, a lot of people in the forecasting community have been asking that question. The emerging answers suggest that, faced with a pair of unusual challenges from Sandy, government forecasters rose to one test and bungled the other…”

Hurricane Sandy Relief Aid Already In Jeopardy In Congress. Nice of our elected representatives to turn Sandy’s recovery into another political freak show; details from MSNBC: “President Obama has submitted a $60.4 billion relief package for areas affected by Hurricane Sandy, which is actually below the total aid request from the governors of New York, New Jersey, and Connecticut, but as promised, Congress is not in a generous mood.

House lawmakers don’t intend to introduce an emergency funding bill anywhere near as large as the $60 billion the Obama administration is seeking to help rebuild the Northeast after superstorm Sandy, saying the administration hasn’t provided sufficient details to justify spending that amount, two senior GOP aides said Wednesday.
If the Republican-controlled House doesn’t take up the measure this year, it would push debate on a large rebuilding bill into next year — something New York and New Jersey officials have said they want to avoid...”

Climate Stories…

Extreme Weather More Persuasive On Climate Change Than Scientists. Some people may not believe peer-reviewed science, but it appears they do believe their own eyes (and personal experiences). Here’s an excerpt from The Guardian: “As one of the Marx brothers famously said: who do you believe, me or your own eyes? Climate sceptics, it turns out, are much more likely to believe direct evidence of a changing climate in the form of extreme weather events than they do scientists, when it comes to global warming. A poll released on Friday by the Associated Press-GfK found rising concern about climate change among Americans in general, with 80% citing it as a serious problem for the US, up from 73% in 2009. Belief and worry about climate change were rising faster still among people who do tend not to trust scientists on the environment…”

AP-Gfk Poll: Belief In Climate Change Rises With Thermometers, Even Among US Science Doubters. Here’s an excerpt from an Associated Press Gfk poll: “Nearly 4 out of 5 Americans now think temperatures are rising and that global warming will be a serious problem for the United States if nothing is done about it, a new Associated Press-GfK poll finds. Belief and worry about climate change are inching up among Americans in general, but concern is growing faster among people who don’t often trust scientists on the environment. In follow-up interviews, some of those doubters said they believe their own eyes as they’ve watched thermometers rise, New York City subway tunnels flood, polar ice melt and Midwestern farm fields dry up….”

IPCC Draft Report Leaked: Shows Global Warming Is NOT Due To The Sun. More on the leaking of the upcoming IPCC report, how it’s being spun by the Climate Denial Machine, and what it really says, at Skeptical Science; here’s an excerpt: “Alec Rawls, an occasional guest poster on the climate contrarian blog WattsUpWithThat who signed up to review the upcoming Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (as anyone can), has “leaked” a draft version of the report and declared that it “contains game-changing admission of enhanced solar forcing.”  This assertion was then repeated by James Delingpole at The Telegraph (with some added colorful language), and probably on many other climate contrarian blogs. If the IPCC were to report that the sun is a significant player in the current rapid global warming, that would indeed be major news, because the body of peer-reviewed scientific literature and data clearly show that the sun has made little if any contribution to the observed global warming over the past 50+ years…”

Early Draft Of International Climate Science Report Posted Online. More on the apparent leak of a (preliminary) IPCC report, due out next September, from The Union of Concerned Scientists; here’s an excerpt: “Yesterday, a blogger who had signed up to review a forthcoming Intergovernmental Panel on Climate Change (IPCC) report on climate science posted unauthorized drafts online. Below is a statement by Peter Frumhoff, Science and Policy Director at the Union of Concerned Scientists and a lead author for the IPCC’s 2007 report: “The report is a draft and will change. Overall, scientific groups like the IPCC recognize that climate change is happening faster and with greater consequences than previously anticipated. Whether it’s the National Academy of Sciences or the United States Global Change Research Program, there is, and will remain a strong scientific basis to inform and motivate policymakers to reduce the serious risks that climate change poses for our nation and the world…”

* Global Warming is not due to the sun, according to leaked IPCC report. The U.K. Guardian has details.

Insurance Industry Paying Increasing Attention To Climate Change. The data is the data – the trends are the trends, as described in this excerpt from Science Daily: “…Weather and climate-related insurance lossses today average $50 billion a year. These losses have more than doubled each decade since the 1980s, adjusted for inflation,” says the study’s author Evan Mills, a scientist in Lawrence Berkeley National Laboratory (Berkeley Lab’s Environmental Energy Technologies division). “Insurers have become quite adept at quantifying and managing the risks of climate change, and using their market presence to drive broader societal efforts at mitigation and adaptation.…”

Libertarians, Engineers, and Climate Disruption Denial: Part 1. The psychology of denial is examined in this post at Scholars and Rogues; here’s an excerpt: “…Ever since I encountered my first example of a climate disruption denier I’ve wondered what kind of person could deny the reality that is industrial climate disruption. Over the years of writing on climate, however, it became clear that there were two groups of people who made up the majority of the serious deniers – libertarians and engineers of various stripes. As an electrical engineer myself, however, I didn’t understand how individuals trained in mathematics, science, and logic could fail to see glaring scientific, mathematical, physical, or logical flaws in their own arguments. Eventually, though, something clicked: most of the engineers I work with today and have worked with since earning my MSEE are either libertarians themselves or have some libertarian leanings. This is the first part of a series of posts exploring the personality traits and moral values of libertarians, engineers, and the relationship of those traits and values to the denial of industrial climate disruption…”

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
