A (Brief) Siberian Swipe
7 of the 10 warmest years in recorded Minnesota history have taken place since 1998. Last winter brought only 3 nights below zero (the latest 30-year running average is 22.5 nights of subzero fun every winter at MSP). The trends are undeniable.
But Earth is still tilted on its axis, nights are still long over the Northern Hemisphere. Cold fronts will still surge southward into the USA.
Saying that a couple of numbing days refute a warming atmosphere is like judging Adrian Peterson from one play, and not looking at his entire career as an NFL running back.
The rumor is true: 2 days with highs below zero next Monday & Tuesday. We may wake up to -15F Tuesday morning. Air temperature.
The coldest outbreak in 4 years. Increasingly rare, but not unprecedented. And hardly the week after week of subzero pain back in the 1970s.
Sunny teens today give rise to a thaw tomorrow. A mild start Saturday, and then we fall over the temperature cliff Saturday night; single digits by Sunday. We probably won't climb above 0F. from Sunday evening into early Wednesday.
We'll make the national news. Your Aunt Ethel will call to make sure you're OK. We'll get thru this, as winter "bottoms out".
Wednesday "Highs". I grabbed this map from 3 pm yesterday, showing the core of the Arctic air pushing slowly south across Canada. We'll get to enjoy some of this fresh air from Sunday into Wednesday morning of next week, probably the coldest spell of winter. Map: Ham Weather.
Thaw, Then Awe. Models show low to mid 30s Friday and the first half of Saturday, followed by a 35 degree temperature drop Saturday night; temperatures hovering just above 0 F. Sunday, then dropping below zero from Sunday evening into at least Tuesday morning. ECMWF keeps us (just) below zero on Tuesday as well, but we finally pull out from under the worst of the chill by Tuesday night and Wednesday.
Old Man Winter Pulling His Punch? We've seen worse, in fact the outbreak in January, 2009 will probably wind up being considerably colder/longer than what we'll experience early next week. ECMWF guidance shows only 1 day below zero (next Monday). If this verifies it will be the first subzero daytime max in just over 4 years. I still think this will be the coldest spell of the winter.
Next Week: Probably The Coldest Of Winter. Could we see a similar subzero blast in February? Possible, but not terribly likely. Historically our coldest day of the year is January 15-16; the best chance of subzero cold often comes 3-4 weeks after the Winter Solstice. The extended NAEFS trends (courtesy of Environment Canada) show temperatures bottoming out early next week, then recovering into the 20s and 30s the last week of January. No significant snow is in sight thru the end of the month.
Rain In Fairbanks? When Alaska is unseasonably mild, Minnesotans usually shiver. Such will be the case early next week. A tenth of an inch of rain, in the dead of winter, in Fairbanks, Alaska, is very unusual. Details from the Alaska office of the National Weather Service: "The anomalous rainstorm that glazed interior roads yesterday, causing school and business closures, produced the most rain Fairbanks has seen from a single January storm in half a century."
Vegas Freeze. While it rains in the interior of Alaska, tourists and locals in Las Vegas are freezing their butts off.

Thanks to both of our weather contributors today - sorry about the untimely cold front.
Top 10 Global Weather/Climate Events of 2012. Here is NOAA NCDC's list of top events; frankly I was surprised by what they picked as the #1 event of last year. Sandy was third on the list: "Meteorologist Paul Douglas takes a close look at a NASA animation showing global temperature trends over the last 100 years. Plus, the National Climatic Data Center (NCDC) ranks the Top 10 Global Weather/Climate Events of 2012, with input from both weather and climate experts. See what topped the list."
A Real Snowbird. O.K. Like most Minnesotans, I plan on weathering next week's Arctic front first-hand. I'm tempted to evacuate for a warmer climate, but part of me (the insane part) wants to experience this first-hand. Thanks to Jeff Edmonson for this photo of a pint-size bird at Twin Cities International Wednesday. Hoping to catch a southbound flight along with everyone else?
The Long Tail Of A Hurricane. Here's an excerpt of an excellent story at NPR: "The House just approved a $50 billion assistance package to victims of Hurricane Sandy — months after the storm wrecked much of the East Coast — although the Senate is yet to vote. Securing relief funds after natural disasters has traditionally been noncontroversial, but with the recent deficit debates, this has been an unusual struggle. And sometimes, funding doesn't seem to be enough. Take Galveston, Texas, for example. In 2008, the city was rocked by Hurricane Ike. And when Sandy Carson went to photograph it a few years later, what he found was a city, in many ways, still in shambles..."

A Mysterious Patch Of Light Shows Up In The North Dakota Dark. Notice the smudge of light in North Dakota? No, those aren't the lights of Bismarck, but a very visual symptom of the scale of fracking going on just to our west. Robert Krulwich has a story at NPR; here's an excerpt: "...What we have here is an immense and startlingly new oil and gas field — nighttime evidence of an oil boom created by a technology called fracking. Those lights are rigs, hundreds of them, lit at night, or fiery flares of natural gas. One hundred fifty oil companies, big ones, little ones, wildcatters, have flooded this region, drilling up to eight new wells every day on what is called the Bakken formation. Altogether, they are now producing 660,000 barrels a day, double the output two years ago, so that in no time at all, North Dakota is now the second largest oil producing state in America. Only Texas produces more, and those lights are a sign that this region is now on fire ... to a disturbing degree — literally..."

36 F. high in the Twin Cities yesterday.
23 F. average high for January 16.
32 F. high on January 16, 2012.
.3" snow fell at KMSP yesterday.
Welcome Thaw. It felt pretty good out there thru midday, with highs in the 30s statewide. Highs ranged from 33 at St. Cloud to 36 in the Twin Cities (37 at Eden Prairie and St. Paul).

Black Carbon Ranks As Second-Biggest Human Cause Of Global Warming. The Washington Post has the story; here's an excerpt: "Soot ranks as the second-largest human contributor to climate change, exerting twice as much of an impact as previously thought, according to an analysis released Tuesday. The four-year, 232-page study of black carbon, published in the Journal of Geophysical Research: Atmospheres, shows that short-lived pollution known as soot, such as emissions from diesel engines and wood-fired stoves, has about two-thirds the climate impact of carbon dioxide. The analysis has pushed methane, which comes from landfills and other forces, into third place as a human contributor to global warming..."

The thick layer of smog lingering over Utah has fouled the state's mountain air so badly that health officials have warned people not to exercise outside and schools are keeping children inside for recess and sports. The smog is blamed on a weather phenomenon that pins pollution to the valley floors." Brian Nicholson / AP
Burning Fuel Particles Do More Damage To Climate Than Thought, Study Says. The New York Times has more details on new research showing the risks posed by black carbon; here's a snippet of a recent article: "...Although some scientists have long believed that black carbon is a major force in climate change, the vast majority of previous mathematical models had predicted that the particles had only a modest impact. That view should now change, said Mark Z. Jacobson, an atmospheric scientist at Stanford University and one of the study’s authors, calling the old models “overly simplistic.” He said that many of his co-authors had previously hewed to the lower estimates. Veerabhadran Ramanathan, a professor of climate science at the Scripps Institution of Oceanography in San Diego who has long campaigned to control black carbon, described the study as highly authoritative. “The fact that it’s written by a very large group of modelers gives it enormous credibility,” he said. “It was lonely before. I’m now glad to be right in the middle...”

Climate Change Series: Where Science And Ethics Meet. Here's an excerpt of a WBUR article that resonated with me: “Global warming,” which sounds gradual and reversible, does not begin to describe the challenge we face today. The obstacle ahead is unstable and irreversible – it is climate change. “Unstable” because the warming of the earth’s atmosphere can set up feedback loops that dramatically change the earth’s fundamental climate patterns. “Irreversible” because once these changes take place, we know of no way to undo them and return to the climate patterns that have existed throughout human civilization...."

For generations, the people of this bone-dry region lived off their herds, but climate change has meant that the normally once-a-decade droughts are now coming every few years."
