Windchill Sting Today - Couple Inches Sunday - Spring Returns Late Next Week

25 F. maximum temperature yesterday in St. Cloud. 
35 F. average high on March 9.
38 F. high on March 9, 2016.

March 10, 2012: The record high of 66 degrees at the Twin Cities is the first of 8 record highs in a 10-day span.
March 10, 1948: Bitterly cold conditions, especially for March, occur in Minnesota. A low of -44 is reported at Itasca.



February Relapse, but 50 Degrees Is A Week Away

Legendary Minnesota winters have been partially defanged. They've lost some of their bite. Today zero is the new 20 below. Snow day? Dream on. Since 1970 meteorological winters in the Twin Cities have warmed 5.4 F. According to Dr. Mark Seeley 15 of the last 20 winters have been warmer than normal.

I explain that roughly 1 in 4 winters now are "old fashioned", with average snow (50 inches or more) and the kind of polar pain that once made Americans wince at the thought of spending a winter here.

Spring has arrived 3 weeks early over the southern half of the USA but a wintry relapse will grip the Midwest to New England into early next week. Today is the coldest day for Minnesota; a chill factor of -10 F at the bus stop this morning. A couple of super-sized clippers will drop plowable snow (3 inches or more) from the Dakotas to Des Moines, Nashville and the Carolinas. Both GFS and ECMWF are printing out 1-2 FEET of snow for the Northeast, including major coastal urban areas, late Monday into Wednesday. Next week may be wild from Boston and New York to D.C.

Once of these clippers will spread light snow into much of Minnesota Sunday PM into midday Monday, and I could see a couple inches  of slush. Whatever falls will melt within 36 hours or so. The beauty of a mid-March snowfall. We get off relatively easy with a couple inches late sunday.

Winter's last gasp? Probably. A mild, Pacific flow returns within 4-5 days. Highs nudge 50 F. in the metro in about a week or so.

Enjoy the cold front!




Short-Term Snow Potential. Clipper #1 takes a more southerly track, spreading accumulating snow from the Dakotas into St. Louis, Chattanooga and the Carolinas - plowable amounts of snow are possible across the Mid South and Carolinas; one of the bigger potential snowfalls of a fairly tame winter season. 84-hour NAM snowfall product: NOAA and Tropicaltidbits.com.


Nor'Easter Risk Grows Early Next Week. Both GFS (above) and ECMWF spin up a major coastal storm capable of 1-2 foot snowfall amounts from near Washington D.C. and Philadelphia and New York. The heaviest amounts may pile up west of I-95 and it's still very early to talk amounts and timing. But it looks ripe, and there should be sufficient cold air in place for a major dumping - possibly the biggest of the winter.

Record-Challenging Cold to Crash into Northeast This Weekend. Jason Samenow reports for Capital Weather Gang: "Following a historically warm February, near-record cold is forecast to spill into the Northeast this weekend. Weekend high temperatures may reach only the single digits and teens in many areas. From northeast Pennsylvania to Maine, these will be some of the coldest afternoon highs ever posted at this time of year..." (GFS model forecast wind chills Saturday morning, Washington Post).

Spring Returns Next Week. It doesn't feel like March out there today with a stinging wind chill. One last dance with January, then fairly rapid moderation next week with a shot at 50 degrees next weekend, according to ECMWF guidance. Twin Cities meteogram: WeatherBell.

Late-March Thaw. I'm still impressed with the intensity and persistence of the subtropical jet stream, intense winds capable of spinning up major, full-latitude storms - with sufficient shear for tornadic thunderstorms in the warm sector. Looking 2 weeks out New England finally warms up; unusual warmth east of the Mississippi River, as another series of storms slams into the west coast.


46 Confirmed Tornadoes in March 6-7 Outbreak. U.S. Tornadoes confirms 63 reports, 90 warnings and 6 watches. Here's an excerpt from a post detailing the biggest tornado outbreaks of 2017, nationally, to date: "...Another in a late-winter and early-spring volley of storm systems, this one was the farthest west outbreak so far this year. While many of the tornadoes were QLCS-type, spinning up within lines and broken lines, several supercells dropped tornadoes as well. The Kansas City area was particularly hard hit as an EF3 struck east of town. Fortunately, no one was killed despite relatively high impact..."

GOES-16 (Combined Vis/IR) Imagery of Monday's Tornado Outbreak. Here's what the squall line over Iowa and Missouri looked like from 22,300 miles above the equator; additional detail provided by Satellite Liason Blog: "...Severe convection developed quickly across the western edge of the SPC risk zone. (Above) is an animation of an image combination known as a “sandwich product”. This is simply transparent 10.4 um IR channel overlaid on 0.64 um visible channel. With this combination, one is getting the benefit of the higher resolution in the visible imagery, and the benefit of the temperature information from the IR imagery. One can clearly see the evolution of overshooting tops, and the rapid expansion of the storm anvils..."

A Note to the Weather Community About Using GOES-16 Data. It's still in beta, so buyer beware. But damn, the imagery is spectacular! Here's an excerpt from NOAA NESDIS: "NOAA's National Environmental Satellite, Data, and Information Service appreciates the enthusiasm in the weather community and support for our newest on-orbit satellite, GOES-16, which will enhance the weather forecasts that save lives and protect property nationwide. At this time, data from GOES-16 are considered preliminary and are undergoing validation testing. NOAA is therefore requesting that any organizations that redistribute GOES-16 data -- before it is declared operational -- include the following disclaimer with the data:
"NOAA's GOES-16 satellite has not been declared operational and its data are preliminary and undergoing testing."

La Crosse County Sees Earliest Tornado on Record.  Wisconsin Public Radio has the story: "Damage in La Crosse County originally attributed to high winds during Monday night’s storm is actually the result of a tornado. The National Weather Service researchers confirmed the tornado after surveying the area Wednesday. The twister touched down north of Barre Mills, skipping northeast for 3 miles. NWS researchers say the storm only lasted for 5 minutes and was rated a EF1 on the 5-point scale used to rate tornadoes. The tornado is the earliest on record in western Wisconsin, after the region experienced a mild end to winter..."




Record Warmth for Meteorological Winter. Yes, it was a top 3 warmest December though February for muh of America east of the Rockies. Here's an excerpt from NOAA NCEI: "The stations shown on the map below had one of their three warmest, coolest, wettest or driest winters on record this year. Stations with a bold white circle saw values that exceed any previous December-through-February value at the station's current location. The smaller circles indicate year-to-date outcomes that were 2nd or 3rd place among a station's history..."

An Early Spring for Much of the USA. This reminds me of the freakishly early spring of 2012. In spite of a wintry flashback later this week and the upcoming weekend from the Northern Plains and Midwest to New England, there's little doubt that spring is coming earlier this year. Here's a spring update from the National Phenology Network: "...In 2017, we see very large anomalies in the southeastern United States on the Spring Leaf Index map, where the Index was met up to three weeks earlier than what is typical for these locations. The timing of leaf-out, migration, flowering and other seasonal phenomena in many species is closely tied to local weather conditions and broad climatic patterns. The Spring Index maps offered by USA-NPN shed light on plant and animal phenology, based on local weather and climate conditions..."



Tech Tornado Researchers Return to Southeast for VORTEX-SE. Another round of in-the-field research is scheduled for mid-May. Here's an excerpt from Plainview Daily Herald: "...Associate professors Chris Weiss and Eric Bruning and graduate research assistants Aaron Hill and Vanna Chmielewski – all from the atmospheric science group within the Department of Geosciences – arrived in Alabama early last week to deploy equipment for the second year of the Verification of the Origins of Rotation in Tornadoes Experiment-Southeast (VORTEX-SE), which runs March 8 through May 8. Team members are now stationed in Huntsville to await signs of potentially dangerous storms. Their equipment includes lightning mapping array sensors that will be deployed ahead of storms to map characteristics of lightning strikes, including size and channel length; dozens of weather balloons to measure changes in temperature, wind and moisture content at different heights; and 24 StickNet platforms that measure temperature, pressure, humidity and wind to understand how atmospheric states change around developing tornadoes. Sixteen StickNets are already in place to gather long-range data while the other eight will be deployed directly in the path of oncoming storms..."

Update on National Hurricane Center Products and Services for 2017. Here's a link to a PDF from NOAA NHC showing what has changed for the upcoming hurricane center, along with new (operational) Storm Surge watches and warnings.

A Land of 10,000 Lakes For Sure. But How About Springs? I had no idea. Here's an excerpt from The Star Tribune: "The Land of 10,000 Lakes also may be the Land of 15,000 Springs. Or many more. Minnesota stands to gain that distinction as the Department of Natural Resources works to build an online inventory of the state’s estimated 15,000 to 22,000 springs. A spring is a natural flow of water from an aquifer — an underground layer of rock — to the earth’s surface, in the definition of DNR research analyst Greg Brick, who began work last year on the spring inventory project. Springs are critical resources even if they go overlooked compared to the state’s beloved lakes, rivers, streams and wetlands..."

8 Fossil Fuel Majors Seen Polluting as Much as U.S. Bloomberg has the story: "Eight of the world’s largest oil companies are responsible for as much of the climate-damaging pollution spewed into the atmosphere as the entire U.S., according to a study by a London-based researcher. Saudi Aramco, Exxon Mobil Corp., OAO Gazprom, the National Iranian Oil Co., BP Plc and Royal Dutch Shell Plc were among the eight companies whose fuel was responsible for a third of emissions from oil and gas, according to the non-profit group CDP. The companies released a fifth of all greenhouse gases outside of farming and forestry since 1988, the year most governments acknowledged man-made climate change as a risk..."

Solar Energy Employs a Higher Percentage of Veterans Than The Rest of the Work Force. There's no reason why coal miners can't be manufacturing solar panels and wind turbines here in the USA. Climate Reality has the story: "...Let’s be clear: environmental regulations and clean energy aren’t the main factors behind declining coal jobs (you have to look at increasing automation in the industry and cheap natural gas for those).  But many Americans who’ve spent their careers working in coal have incredibly valuable skills that – with the right policies and training initiatives – can be put to use in well-paying solar and wind jobs with a future. A recent study found that solar’s rapid and projected continuing expansion offers workers in shrinking fossil fuel industries real career opportunities – and we’re already seeing the proof. Just look at the success of Solar Ready Colorado, which is working to retrain hundreds of laid-off coal miners and veterans in Colorado’s Delta County – a region that’s lost over 1,000 coal mining jobs in just the past three years – for long careers in the solar industry..."

Clean Energy Is Now as Big as Pharmaceutical Manufacturing in the U.S. Here's a clip from Vox: "...In the US, the story is much the same: The advanced energy industry is big! As of last year, it brought in $200 billion in revenue, which is “nearly double beer sales, equal to domestic pharmaceutical manufacturing, and approaching wholesale consumer electronics.” That’s up 28 percent since 2010. The industry now supports 3.3 million jobs in the US..."

Solar Power Growth Leaps by 50% Worldwide Thanks to U.S. and China. The Guardian reports: "The amount of solar power added worldwide soared by some 50% last year because of a sun rush in the US and China, new figures show. New solar photovoltaic capacity installed in 2016 reached more than 76 gigawatts, a dramatic increase on the 50GW installed the year before. China and the US led the surge, with both countries almost doubling the amount of solar they added in 2015, according to data compiled by Europe’s solar power trade body..."

Will Electric Cars Soon Have Solar Roofs? Toyota and Tesla Say Yes. Driving for free - what a concept. Here's an excerpt from ThinkProgress: "Last week, Panasonic announced an advanced solar panel system that will debut on the 2017 model Toyota Prius plug-in hybrid in Japan (the Prius Prime). It is “the first commercially available, mass-produced passenger car to feature an optional solar charging system,” PV magazine explained. Panasonic notes that, previously, rooftop solar cells had outputs of only “several tens of watts.” So they were used only for ventilating parked cars and “auxiliary charging” of the standard 12-Volt lead-acid battery. But improvements in solar efficiency combined with advanced design and “technologies to laminate three-dimensional curved glass” have allowed a high output — some 180 watts, which is more than triple the output of the previous solar roof..."

Bentley's First-Ever, Electric Concept Car is a Luxury Fever Dream. BloombergPursuits has more details: "Although most of the notable debuts at the Geneva Motor Show are teased months ahead of time, Bentley came out swinging on Tuesday with a surprise showing of the marque's first-ever, pure-electric concept. The Bentley EXP 12 Speed 6e Concept is meant to explore the possibility of Bentley producing a true all-electric vehicle for production; it’s a separate endeavor from the recently promised plug-in hybrid Bentayga SUV, which is due out in 2018. If it is received well by VIP guests and analysts at future car circuit stops in Shanghai and Pebble Beach, Calif., said execs, the convertible could lead to an electric vehicle from Bentley by 2021. (The car, while drivable, is one of one, so in order to prevent damage it will not be available for prospective buyers to drive.)..."

With Claims of CIA Hacking, How to Protect Your Devices. Here's a clip from The New York Times: "...Many iPhone owners are far more up-to-date with their mobile software than Android device owners. So only a minority of iPhone users have devices with the versions of the Apple iOS operating system that the WikiLeaks documents mention. Specifically, the WikiLeaks documents referred to exploits working on versions of iOS up to 8.2. About 79 percent of Apple users are running iOS 10, the latest version of the system, and only 5 percent are running a version older than iOS 9, according to Apple. In raw numbers, with more than one billion iOS devices sold worldwide, that amounts to at least 50 million people running the outdated software..."

Cable Cars are Changing the World. Increasingly they are seen as a cost-effective way of transporting people across urban areas, according to How We Get to Next: "...Countries around the globe are now rushing to construct cable car systems in much the same way that they were rushing to construct monorails a few decades ago. The success of the Medellín project inspired its local neighbor, Caracas, to construct its own mass transit cable car, as well as other projects in Brazil, Bolivia, Chile, Peru, and Colombia’s capital, Bogotá. In Iran, the Tochal Telecabin system carries winter sports enthusiasts from the city of Tehran to the enormous Tochal ski complex. In Armenia, the Wings of Tatev cable car ferries religious tourists to the Tatev monastery year-round. Mexico City has a proposal for a cable car, as does Haiti, Vietnam, Lagos, Mombasa, and many other places. The list of current proposals that The Gondola Project tracks is enormous..."

Where Residents are Happiest - and Not so Cheery. The happiest people in America live in Naples, Florida? CNN.com has details: "...The Naples-Immokalee-Marco Island metro area was tops in contentment for the second year in a row, according to the Gallup-Healthways 2016 well-being rankings. The survey says residents there feel safer than residents in any other community in the nation. The Town of Barnstable, Massachusetts, and Santa Cruz-Watsonville, California, took second and third place overall in the composite index. The border city of Fort Smith, Arkansas, on the other hand, ranked lowest of 189 communities measured. Gallup measures the well-being of a community based on interviews gauging resident's feelings about their financial position, community, health and safety..."

Hot Story: Miami Lawyer's Pants Erupt in Flames During Arson Trial in Court. You just can't make this stuff up. The Miami Herald reports: "...A Miami defense lawyer’s pants burst into flames Wednesday afternoon as he began his closing arguments in front of a jury — in an arson case. Stephen Gutierrez, who was arguing that his client’s car spontaneously combusted and was not intentionally set on fire, had been fiddling in his pocket as he was about to address jurors when smoke began billowing out his right pocket, witnesses told the Miami Herald. He rushed out of the Miami courtroom, leaving spectators stunned. After jurors were ushered out, Gutierrez returned unharmed, with a singed pocket, and insisted it wasn’t a staged defense demonstration gone wrong, observers said..."

February's Warmth, Brought To You by Climate Change. How much of the recent, freakish, warmth is natural vs. attributed to background warming? Here's an excerpt from Climate Central: "A bonanza of heat records fell throughout February in almost all quarters of the U.S. and research released on Wednesday shows that this pervasive spring-like warmth was made possible by climate change. The rise in planetary heat made the freakishly warm February at least three times more likely than it was around 120 years ago, according to the analysis by scientists working on the World Weather Attribution team. While it was a month to remember, by mid-century that type of heat could occur every three years unless carbon pollution is curtailed. The warm spell is just the latest piece in a growing body of evidence that climate change is playing a role in almost all extreme heat events. Winter is the fastest warming season in the U.S. and February is no exception. February temperatures in particular have risen by 3°F since 1895, which is roughly twice as fast as the global average..."

What Keeps Global Security Academics Awake at Night? Here's an excerpt from The Interpreter: "...By a factor of three, the key threat to global security identified was climate change. For many, climate change constituted the most fundamental existential threat, especially if our focus is the global rather than the national. As one respondent put it, ‘the globe can survive most other things’. At second place was poverty and inequality. Respondents noted the ongoing devastating effects of poverty and the effects of growing inequality on both life choices and the surge of destructive ideologies. On this score, nationalism finished a close third, with respondents pointing to the dangers of a world of states turning inward even while global action to address global problems (like climate change) seems more necessary than ever..."

Chronology of Military and Intelligence Concerns About Climate Change. Here's an excerpt of a story at The Center for Climate & Security: "...This concern didn’t happen overnight, or under a single administration. Rather, it’s the culmination of decades of assessments stretching back to the end of the Cold War. In popular discourse, it’s often assumed that climate change is a brand new issue for the national security world – an interloping latecomer. The truth is that it’s not. The U.S. military has been concerned about climate change since the George W. Bush Administration, at the latest, but military institutions such as the Naval War College have been warning policy-makers since 1990, during the first Bush Administration. The intelligence community has also been in the game since the early 1990s, with the establishment of the MEDEA program – a structured collaboration between climate scientists and U.S. intelligence agencies – and has been releasing intelligence estimates on the national security implications of climate change since 2008, under the direction of then Chairman of the National Intelligence Council, Dr. Thomas Fingar..."



These are the 158 Key Federal Science Data Sets Rogue Programmers Have Duplicated So Far. Quartz has the story: "...These “data rescue” events have managed to archive tens of thousands of government website pages they fear may be edited or removed under an administration that has expressed hostility towards climate and environmental science. Copies of those web pages now live within the Internet Archive, best known for its Wayback Machine platform. But the Internet Archive can’t scrape more elaborate databases—so in addition to simple web pages, the groups pull down intricate and often large data sets from science agencies like NASA, the US Environmental Protection Agency, and the US National Oceanic and Atmospheric Administration, all three of which have been singled out by the Trump administration for budget and staffing cuts to their earth and climate science programs. Since January, 158 complete data sets have been downloaded, labeled, and re-uploaded to DataRefuge.org, a growing repository of scraped government science..."

Addressing Climate Change is Prudent. Here's an excerpt of an Op-Ed at Cincinnati.com that resonated: "...Mr. Kleine is correct in stating that science is never completely settled; it is the nature of inquiry to constantly keep exploring and asking questions. There does reach a point, however, where the major pieces of the puzzle emerge. Such is the case with climate change resulting from global warming. There is high confidence that the earth is warming and that human consumption of fossil fuels is a major contributor. While the science is not 100 percent certain, the level of confidence in these conclusions is about the same as the confidence needed for a prescription drug to be judged effective for use. Said differently, the level of confidence in climate change is high enough to do something about it. The challenge with global warming is that it takes broad political agreements to induce the kind of societal changes needed to address the problem. Wanting to act is not a liberal or radical idea; it is simply prudent..."

Only Sci-Fi Can Drown Manhattan and Make You Want to Live There. Bloomberg Businessweek takes a look at Kim Stanley Robinson's upcoming book, "New York 2140": "...Robinson’s baseline scenario might be too aggressive. Benjamin Strauss, vice president for sea level and climate impacts at Climate Central, a nonpartisan, nonprofit environmental group, says a 15-foot rise, not a 50-foot one, is more likely by 2140. That would still mean standing water in Manhattan’s Lower East Side, Chelsea, and the Financial District. John F. Kennedy International and LaGuardia airports would be submerged. At 50 feet, Strauss says, “you certainly would have enough water for Venice,” but he’s more optimistic that the city will prevent flooding than is Robinson. “The geography of the area allows the building of a barrier,” Strauss says. “My guess is that we will build a wall and sit tight” before the water reaches Times Square. 2140 arose from Robinson’s conviction that the free market sets prices incorrectly. “The system set up now is a system of laws, and it’s an artificial system,” he says. “The laws could be rewritten to prioritize the survival of the species...”

Spring Came Early. Scientists Say Climate Change is a Culprit. Here's an excerpt of a New York Times analysis: "...The new research shows a strong link between global warming and the very warm February that helped to drive the extremely early spring this year. For the entire continental United States, February 2017 was the second warmest on record, and mean temperatures were especially high east of the Rockies: as much as 11 degrees Fahrenheit above normal. The study, by scientists working as part of a group called World Weather Attribution, looked at the influence of climate change on the temperatures, using models of the atmosphere as it exists and of a hypothetical atmosphere with no greenhouse gas emissions and thus no human-driven climate change. They found that a warm February like the one just experienced is about four times more likely in the current climate than it would have been in 1900, before significant emissions began to change the climate..."


A Tornado in Early March? In Minnesota? Really? Republican Tim Reckmeyer makes a convincing case for bipartisan action in this Op-Ed at Star Tribune; here's an excerpt: "...In colder climates, like ours, winter-based recreational activities, like skiing, ice fishing, and snowmobiling are less prevalent. This has effects on local businesses and kids who just want to play pond hockey throughout winter. The frequency of Lyme disease in Minnesota is increasing because more disease-carrying insects, like ticks, survive milder winters. Allergy season is already 21 days longer than it was in 1995, and pollen counts are rising, which can trigger respiratory illnesses for allergy sufferers. This can have deadly implications for children and the elderly. The most important actions we can take are to support smart progrowth economic policies that reduce our energy waste and fully embrace clean energy to power our modern world. Doing so will stabilize our climate and winters, reduce the risks of further damage to our economy, and immediately provide better health via cleaner air and water..."

Study: Climate Change May Hurt Nation's Agricultural Productivity. Here's an excerpt from Iowa Public Radio: "...They found that without changes to farm policy and improvements to agricultural technology, the nation’s productivity in 2050 could look like it did in 1980. That’s because at the present rates of innovation, new technologies won’t be able to keep up with the damage caused by the changes in climate in our major growing regions. Lead author Xin-Zhong Liang, a professor at the University of Maryland, says both policymakers and those who work directly in agriculture should consider changes that might prevent this drop. On the policy side, Liang said, changes to  water management could help. On the technology side, the development of seeds that can withstand more extremes of heat and rain would likely help mitigate the climate’s impact on overall productivity..."

Trees Might Not Be Able to Store as Much Carbon As We Thought, New Study Suggests. An article at CNBC highlights new research raising concerns that soil nutrients may not be sufficient for plants to process increasing CO2 efficiently: "Researchers at Western Sydney University (WSU) in Australia have found that "common" Australian trees do not store as much carbon as had been previously assumed, a discovery that could have big implications on how we tackle climate change. According to a news release from the university, the study, published in the journal Nature Climate Change, found that Eucalyptus forests may require extra soil nutrients to grow and "take advantage" of additional carbon dioxide (CO2) in the atmosphere. Large areas of "remnant native eucalypt forest" were exposed to heightened levels of CO2 at a WSU facility. Researchers found that while the extra CO2 increased levels of photosynthesis, it did not result in increases in leaves, stems and wood..."
