-9 F. morning low on Wednesday.
2 F. high yesterday afternoon at KMSP.
30 F. average high on February 18.
44 F. high on February 18, 2014.
1″ snow on the ground in the Twin Cities.
February 18, 1928: A dust storm moved across Minnesota, causing lights to be turned on in the day time in the Twin Cities.
There’s no shame in flying, driving or walking south for a mid-winter break. A good friend, Bill Popp, reminded me that even Minnesota’s state bird, the loon, flies south for the winter, relocating along the Gulf coast.
Except that may not be far enough south. Mardi Gras revelers in New Orleans have been decked out in heavy coats; wind chill advisories posted for much of Florida. You may have to fly to Phoenix, San Diego or Mexico to work up a serious sweat because an almost January-like chill will linger east of the Rockies into late February. No, spring is NOT right around the corner.
This morning starts out colder than yesterday but winds are easing under the center of a high pressure bubble. The wind chill won’t be nearly as gasp-worthy. And the sun will be out, removing some of the psychological sting.
An inch of snow on Friday gives way to another thumb-numbing slap over the weekend; daytime highs barely creep above zero Sunday, again Wednesday of next week – with a wind chill that may tempt you to put your travel agent on speed-dial.
A higher sun angle and longer daylight finally gives the mercury a good kick the first week of March. 30s may feel like a revelation!

Pulses of Pain. A few more smacks of Siberian air are shaping up into the end of next week; the end of February; the brunt of subzero temperatures from the Dakotas and Upper Midwest into the Great Lakes and New England. 2-meter temperature animation: NOAA and Ham Weather.
Cold and Dry. European guidance shows another surge of subzero air Sunday into early Monday, again the middle of next week. Highs Friday may surge into the 20s before temperatures beat a hasty retreat late Saturday into Sunday. Not exactly polar, school–closing cold, but chilly enough to spark more griping and general irritability. This is what we get for a relatively mild December and January. Graphic: WeatherSpark.
March Thaw. At some point the wicked winds of winter will ease, in response to a higher sun angle and an eventual wind shift to the west or southwest within 2 weeks. At least one NOAA model shows 30s pushing into Minnesota by March 1, with 40s over southwestern counties. Source: Ham Weather.
Looking Forward To March. What snow lovers are hoping for is a persistent trough of low pressure out west, one that turns our winds aloft to the southwest, pumping tropical moisture northward. That will probably happen by mid-March, but will there be enough cold air in place by then for mostly snow? No way to know, but 500 mb winds on Wednesday evening, March 4 are forecast to be howling from Las Vegas, not Saskatoon, based on GFS guidance. Source: GrADS:COLA/IGES.
Why Tesla’s Battery For Your Home Should Terrify Utilities. Free power from the sun, powering your home? The concept may not be as outrageous as it sounds, according to a story at The Verge; here’s a snippet: “…The prospect of cheap solar panels combined with powerful batteries has been a source of significant anxiety in the utility sector. In 2013, the Edison Electric Institute, the trade group for investor-owned electric companies, issued a report warning that disruption was coming. “One can imagine a day when battery storage technology or micro turbines could allow customers to be electric grid independent,” the report said, likening the speed of the coming transition to the one from landlines to cellphones 10 years ago. Suddenly regulated monopolies are finding themselves in competition with their own customers...”
Get Ready for $10 Oil. Bloomberg View has the Op-Ed, here’s an excerpt: “At about $50 a barrel, crude oil prices are down by more than half from their June 2014 peak of $107. They may fall more, perhaps even as low as $10 to $20. Here’s why. U.S. economic growth has averaged 2.3 percent a year since the recovery started in mid-2009. That’s about half the rate you might expect in a rebound from the deepest recession since the 1930s...”
Last Week Tonight With John Oliver: Tobacco. Mr. Oliver is doing enterprise reporting that would make network news divisions jealous. In case you missed it here’s a YouTube link to a recent story about tobacco that made me do a double-take: “Thanks to tobacco industry regulations and marketing restrictions in the US, smoking rates have dropped dramatically. John Oliver explains how tobacco companies are keeping their business strong overseas.”
Our Fear of Artificial Intelligence. Are our fears overblown? Here’s an excerpt from a long but excellent read at MIT Technology Review: “…No one is suggesting that anything like superintelligence exists now. In fact, we still have nothing approaching a general-purpose artificial intelligence or even a clear path to how it could be achieved. Recent advances in AI, from automated assistants such as Apple’s Siri to Google’s driverless cars, also reveal the technology’s severe limitations; both can be thrown off by situations that they haven’t encountered before. Artificial neural networks can learn for themselves to recognize cats in photos. But they must be shown hundreds of thousands of examples and still end up much less accurate at spotting cats than a child…”
Sizzle For A Cause. I hope you can stop by Bayview Event Center in Excelsior, sample some amazing food and support the ICA Food Shelf, which serves 800 homes every month. Tickets and details are here.

NASA Study Predicts Devastating Droughts During The Last Half of the Century. Gizmag has a good summary of recent news coming out of NASA; here’s the intro: “A new NASA study is predicting the occurrence of severe “megadroughts” across the United States in the second half of this century, that are set to be more extreme and prolonged than any droughts that have taken place in the region for the past 1,000 years. According to the study, one of the key driving forces behind the devastating droughts will be the prolific creation of human-produced greenhouse gasses. The study made use of several climate models including one spearheaded by NASA, and is the first of its kind to use historical data stretching back as far as 1,000 years…”

BP’s Two-Word Fix For Global Climate Change. A tip of the hat to BP for acknowledging the elephant in the living room, and proposing the same market-based solution many others are advocating. Here’s an excerpt of a good summary at Christian Science Monitor: “…In its report, BP lays out a variety of ways policymakers and businesses could prevent that from happening, including boosting renewable energy production, limiting carbon-heavy coal use, and making energy systems more efficient. It concludes that no one approach will be enough to meet emissions reductions goals, but offers a simple idea that would help guide efforts: carbon pricing…”
The Risks of Climate Engineering. Here’s a clip from a New York Times article: “…Beneath the identifiable risks is not only a gut reaction to the hubris of it all — the idea that humans could set out to regulate the Earth system, perhaps in perpetuity — but also to what it says about where we are today. As the committee’s chairwoman, Marcia McNutt, told The Associated Press: The public should read this report “and say, ‘This is downright scary.’ And they should say, ‘If this is our Hail Mary, what a scary, scary place we are in….”
New Study Calls For Urgent Action To Prepare New York City. The Big Apple may be hit disproportionately harder than many large coastal cities as sea levels continue to rise, due to a variety of factors. Here’s an excerpt from Gothamist: “…The news gets worse. The sea level will increase between 11 inches and 21 inches by the 2050s; by the 2080s, it’ll be up to between 18 and 29 inches, and by 2100, we can expect an increase of between 22 and 50 inches. And if the science gods are against us—and aren’t they always?—that sea level could see a rise as high as six feet by 2100. Bye, Red Hook! In fact, by 2100, sea level will have risen so much it’ll have doubled the area for 2013’s designated coastal flooding zones for both the 100-year flood and the 500-year flood, leaving a lot of previously untouched inland vulnerable…” (Graphic source here, Wiley Online Library has a link to the full report here).
The Weird Way That Climate Change Could Lead To New Disease Outbreaks Around The World. The Washington Post takes a look at how a rapidly morphing climate is impacting disease vectors; here’s an excerpt: “Climate change could be behind more than just rising ocean levels, melting polar ice caps, and extreme weather events – it could also be creating the ecological basis for infectious diseases to spread to new places and new hosts. Writing in the Philosophical Transactions of the Royal Society B, two prominent zoologists, Daniel Brooks of the University of Nebraska-Lincoln and Eric Hoberg of the U.S. National Parasite Collection of the USDA’s Agricultural Research Service, warn that outbreaks of infectious diseases such as West Nile virus and Ebola are just the start – global warming could enable similar types of diseases to emerge and thrive in places you might not expect...”
More Infectious Diseases Emerging Because of Climate Change. Following up on the story above, here’s an excerpt from a story at phys.org: “…Each has observed the arrival of species that hadn’t previously lived in that area and the departure of others, Brooks said. “Over the last 30 years the places we’ve been working have been heavily impacted by climate change,” Brooks said in an interview last week. “Even though I was in the tropics and he was in the Arctic, we could see something was happening...”
Birds Tell An Urgent Climate Change Message. Huffington Post takes a look at how bird migrations are reflecting temperature trends; here’s the intro: “The canary in the coal mine.” That phrase has become part of the lexicon as a warning for danger. Now birds are cautioning humans about the imminent threat of climate change — and the news is not good. This from a report based on seven years of research by the National Audubon Society. I checked out their website, which featured material on environmental events — both national and international. I learned that the Baltimore Oriole may no longer be in Maryland by the end of the century and that coastal species, like the sandpiper, were imperiled by rising sea levels...”
