Keeping It Official
For the sake of ease, continuity and accuracy official NOAA and FAA weather measurements are taken at airports around the nation. The Twin Cities official weather observations are hourly snapshots at MSP International.
But all weather, like politics, is local. This last snowstorm only brushed the airport with .3 inches of slush; a total of 69.8 inches this winter at MSP. But locals up in Mora, far north metro, would beg to differ. 94.2 inches of Sweet Saskatchewan Slush has piled up there this winter season; close to the 1930-31 record of 99.5". Hayward, Wisconsin has seen a record, jaw-dropping 108.1 inches!
At 75.5 inches St. Cloud is tied for the 5th snowiest winter on record; the 6th snowiest April, with 12 inches and counting.
I think the heavy snow is over now. Let's tempt fate. If it snows more than 2 inches I will personally power-wash & wax Amelia Santaniello's minivan. There. What can go wrong.
A sudden warm front lifts spirits into Monday; highs well into the 60s. Above average! Watch for a late-day T-shower today - more showers possible late Easter Sunday; again midweek.
We cool off into the 50s late next week but no more front-page-worthy mega-snows.
Trust me, I'm a weatherman.
A Springy 72 Hours. ECMWF guidance suggests upper 60s to near 70F each of the next 3 days. Getting to 70F will be a function of how long the sun stays out (and any rain will keep temperatures a few degrees cooler). We cool off a bit Tuesday; another round of potentially heavy showers and T-storms late Wednesday into Thursday. Light jackets stage a comeback by next Friday. Graphic: Weatherspark.
Easter Sunday National Outlook. With the exception of cool weather over much of New England, most of America experiences a mild Easter Sunday, even northern cities from Minneapolis to Chicago and Detroit. Good timing on this latest warm front. Graphic: WeatherNation TV.
7-Day Rainfall Forecast. GFS guidance shows 1-3" amounts pushing into the Pacific Northwest, some 3-5" rains capable of flash flooding into the weekend over Georgia, South Carolina and the Florida Panhandle. An upper level disturbance pushing across the Upper Midwest may drop some 1-2"+ amounts on southeastern Minnesota and central Wisconsin late Saturday into Monday morning. Source: NOAA and HAMweather.
Near-Record Breaking Winter Snowfall at Mora. Yes, the official NWS measurements are taken at MSP International, but snowfall amounts this past winter were much higher over the northern suburbs. Case in point: Mora, where 94.2" of snow has fallen this winter, close to the all-time record of 99.5" in 1930-31. Graph courtesy of the Twin Cities National Weather Service NOWdata.
Above Average Snowfall for MSP. Normal winter snowfall, to date, at MSP International Airport is 53.8". So far 69.8" of snow has piled up in Richfield, according to NOAA records.
Doubly Taxing. As if April 15 isn't tough enough. Dr.Mark Seeley has some trivia about April 15's weather that made me do a triple-take. Here's an excerpt of the latest edition of WeatherTalk: "...Tax filing day in 2014 will likely be remembered as the coldest April 15th in state history (or at least a rival to 1875, 1935, and 1962 as among the coldest). Scores of Minnesota weather observers reported new record lows for April 15th, and the National Weather Service Cooperative weather observer at Camp Norris (Lake of the Woods County) reported a new all-time statewide low temperature for the date with a reading of -4 degrees F..."
Let's shift gears and acknowledge that the pattern is (finally) shifting into spring...
Will The Next El Nino Break A Global Temperature Record? Not al El Ninos are created equal. The really big warm phases of ENSO, the ones that lead to global temperature records, tend to be EP or Eastern Pacific El Ninos. The CP (Central Pacific) warmings tend not to have as great an influence on global temperature. Climate scientist Simon Donner explains at Maribo; here's an excerpt: "...This has important implications for the “pause” in surface warming. Over the past 10-15 years, the easterly winds have been abnormally strong, with few gaps sufficient to generate Kelvin waves. This is related to decade-scale variability in the Pacific Ocean conditions, called the Pacific Decadal Oscillation (PDO) or Interdecadal Pacific Oscillation (IPO). It may then come as no surprise that all the El Nino events since 1998, including the 2009/10 event that made the cherries blossom early in Vancouver, have all been of the CP variety. The same happens to be true for other “slowdowns” in the rate of global surface temperature change since the Industrial Revolution. This suggests the decade-scale variability in the Pacific affects El Nino development, and in turn, the ups and downs in the rate of human-caused global surface warming..."
Average Data Of The First Tornado Warning? Iowa Environmental Mesonet put together an interesting graphic, showing the average first Tor Warning, office by office. As early as January 24 in Jackson, Mississippi, March 11 in Oklahoma City, May 2 in Denver, May 9 in Washington D.C. and May 12 in the Twin Cities. Can we please have a few quiet weeks between the snow and the tornadoes?
Spewing Sewage Into The Ocean Is Bad: Toxic Algae and Man-Size Jellyfish Edition. Remind me not to take a dip in the South China Sea anytime soon after reading this post from Quartz. Here's a clip: "...In July 2013, the biggest algal bloom ever recorded in China covered 28,900 square kilometers (11,158 square miles) of the Yellow Sea—meaning more than three New York City metro areas of ocean was carpeted in green muck—requiring Qingdao city officials to bulldoze 7,335 tonnes (8,085 tons) of beached scum. A similar incident almost shut down the sailing competition of the 2008 Beijing Olympic Games. The army dispatched 15,000 soldiers to remove 1 million tons of algae, costing more than $100 million..."

Pollution From Asia Makes Pacific Storms Stronger. It's all about the aerosols, man-made pollutants seeding clouds and ultimately storms hundreds, even thousands of miles downwind. Is Chinese pollution impacting our weather? Here's a clip from National Geographic: "...Whether the weather [in North America] will change in a good direction or bad is hard to say at this time," says Renyi Zhang, a professor of atmospheric sciences at Texas A&M University in College Station. Zhang is a co-author, along with several scientists from the U.S. and China, of a study released in the Proceedings of the National Academy of Sciences on Monday. The scientists say pollution from Asia is likely leading to stronger cyclones in the midlatitudes of the Pacific, more precipitation, and a faster movement of heat from the tropics toward the North Pole. As a result of these changes, "it's almost certain that weather in the U.S. is changing," says Zhang..."
California Suffers Astonishingly Fast Snowpack Melt As Drought Intensifies. It's going to be a long, hot, potentially fiery summer and autumn for California and much of the Southwest. Andrew Freedman has more details in a story at Mashable; here's a clip: "...Officials already knew that the snowpack was unusually thin and would provide below average amounts of water when it melted, considering that the state had its third-driest winter on record, following its driest calendar year in 2013. However, they did not anticipate it would melt so quickly. The California state snow survey on April 1 found that the snowpack contained just 32% of the average water content at that time of year, when snowpack typically reaches its annual peak. This placed 2014 as among the lowest water-content years on record since such data began in 1930..."

California's Wildfire Threat Is So Severe That The Season Started Early. Following a deepening drought and unusual heat during the winter months, 2014 promises to be a very rough year on the wildfire front. Here's an excerpt from Huffington Post: "Don’t let the recent rains and green hillsides fool you -- the California Department of Forestry and Fire Protection says the fresh growth is only covering up months of dry, dead grass, putting California at risk for one of its most severe fire seasons ever. Warnings issued to homeowners in the state’s most wildfire-prone areas urged them to prepare earlier than ever for the summer fire season in light of California’s historic drought, ABC News 10 reported..."
California Drought To Push Produce Prices Higher. AZCentral has the story; here's an excerpt: "Drought conditions in California's agricultural fields are going to push prices higher for fruits and vegetables, according to a Arizona State University study. The biggest price hikes are likely for lettuce, up 34 percent, and avocados, up 28 percent, according to Professor Timothy Richards of W. P. Carey School of Business at ASU. "You're probably going to see the biggest produce price increases on avocados, berries, broccoli, grapes, lettuce, melons, peppers, tomatoes and packaged salads," Richards said..."

The Drought Hitting 40% of the Entire Country, in 5 Maps. The Washington Post has the story - here's an excerpt: "...Every inch of five states — California, Nevada, Arizona, New Mexico and Nebraska — are experiencing some level of drought. Much of the northern Texas Panhandle is under extreme or exceptional drought warning, as is most of California and parts of northern Nevada. A weekly snapshot of drought conditions shows 21 percent of the country is experiencing severe drought or worse; all told, 40.9 percent of the country is under some kind of drought watch or warning...."

Silver Lining. Those piles of April slush lingering in your yard have some benefits: they've delayed allergy season, and moisture is trending above average. NOAA may remove the drought designation for parts of central and southwestern Minnesota in the coming weeks if these (wetter than normal) trends continue.

Despite all the public education, a staggering 84 percent of people surveyed still believe wind, not water,is the greatest threat to their safety, and base their evacuation decisions on wind speed or a storm’s category, the Federal Alliance for Safe Homes said this week.
The national Harris Interactive Survey, commissioned by the nonprofit group FLASH, revealed “frightening perceptions,” FLASH said Tuesday in a release.
The survey clashes with the reality that hurricane evacuation zones are based on the threat of water, not wind, and nearly all evacuation orders reflect the threat of inland flooding and storm surge.- See more at: http://blogs.palmbeachpost.com/eyeonthestorm/2014/04/15/hurricane-survey-waters-the-threat-but-most-fear-wind/#sthash.6UHHm3wb.dpu
Hiawatha Bray recalls the moment that inspired him to write his new book, You Are Here: From the Compass to GPS, the History and Future of How We Find Ourselves. "I got a phone around 2003 or so," he says. "And when you turned the phone on—it was a Verizon dumb phone, it wasn't anything fancy—it said, 'GPS'. And I said, 'GPS? There's GPS in my phone?'" He asked around and discovered that yes, there was GPS in his phone, due to a 1994 FCC ruling. At the time, cellphone usage was increasing rapidly, but 911 and other emergency responders could only accurately track the location of land line callers..."Boston Globe technology writer

Easter's Coming. Beware Bunny Ears? Oh the shame. The Washington Business Journal has a nugget in this article that made me think back to the days of Easter Egg baskets - did I steal from my kids? Uh oh. Here's an excerpt: "...The Washington-based trade group says Americans will spend $2.26 billion on candy this Easter, up 4 percent from last year. The increase is largely because Easter is three weeks later than it was last year. The association says 87 percent of parents will buy or create Easter baskets for their kids and 81 percent of them will steal candy back from their kids' Easter stash..."

Why Western Wildfires Keep Getting Bigger. Here's a clip from the web site vox.com: "...So what's driving this? Global warming is one likely suspect. "The really amazing thing is that we don't just see an increase in one or two regions," says lead author Philip Dennison, a geographer at the University of Utah in Salt Lake City. "We're seeing it almost everywhere — in the mountain regions, in the Southwest. That tells us that something bigger is going on, and that thing appears to be climate change." The study itself stops short of estimating how much of the increase might be caused by global warming — especially since other factors, such as forestry practices and invasive species are likely at play, too. But their finding is in line with previous research suggesting Western fire activity will become more common as temperatures rise..."

Universities Must End Financial Ties to Climate Denying Fossil-Fuel Giants - Now. Where does the University of Minnesota stand on this issue? There's an opportunity for the U to take a true leadership role with divestment. Here's an excerpt of an Op-Ed at The Guardian: "There are many compelling reasons for universities to divest themselves of investment in the fossil fuel industry – including and especially the physical and potentially irreversible effects of climate change to which university endowments essentially contribute. But for our colleagues now asking for an end to these investments, there's an almost equally compelling argument: universities exist to foster knowledge, learning and understanding, and the fossil-fuel industry has worked systematically over the past 20 years to undermine that work. It has worked and continues to work in direct opposition to our mission as scientists and educators through the political process and PR campaigns..."

Why This Is A Dark Time For The Field Of Climate Science. The Huffington Post has the story - here's the introduction: "These are dark times for science -- in particular, climate science and related fields of study. Hate mail, harassment campaigns, accusations of scientific fraud and threats of lawsuits have become the new normal for climate scientists and researchers who study climate change denial. These problematic conditions have a chilling effect on scientific research. So what happens when a scientific journal becomes part of the problem?..."
Pseudoskeptics Are Not Skeptics. Scientists are, as a profession, skeptical by nature. Science is organized skepticism. But organized denial, orchestrated, well-funded skepticism of climate science? That's something altogether different, as explained at DeSmogBlog: "Genuine scientific skepticism is not just the unmoving rejection of evolution or climate change by fake skeptics, called pseudoskeptics. The real thing avoids premature conclusions, recognizes uncertainty, motivates searches for good data and causes real skeptics to change their minds, as put succinctly by John Maynard Keynes: “When my information changes, I alter my conclusions. What do you do, sir?”....
Drunken Trees: Dramatic Signs of Climate Change. Seeing is believing, unless one chooses not to see. Here's a clip from National Geographic: "Sarah James, an Alaska Native elder, says global warming is radically changing her homeland. Even the forests no longer grow straight. Melting ground has caused trees to tilt or fall. "Because permafrost melts, it causes a lot of erosion," says James, who lives in Arctic Village, a small Native American village in northeastern Alaska. "A lot of trees can't stand up straight. If the erosion gets worse, everything goes with it..."

The High Cost of Climate Change Denial. Here's a segment of an Op-Ed from The San Antonio Express-News: "...In fact, there is a wide scientific consensus. Reluctance to act in go-slow or denier quarters likely has more to do with the perception that doing what needs to be done will slow economic growth. This is shortsighted. While one of these U.N. reports acknowledges an initial slowing, it also says countries will be richer by the end of the century than they are today. The price should be calculated according to what costs will come to roost if these scenarios unfold, not just short-term effect. The future is clear and harsh: Without action, people will have to live with the effects of climate change for hundreds and hundreds of years..."
Virginia Supreme Court Rule For U-Va. in Global Warming FOIA Case. It's a victory for academic freedom and scientific research, free from political or ideological influence, as reported by The Washington Post; here's a clip: "Unpublished research by university scientists is exempt from the Virginia Freedom of Information Act, the Virginia Supreme Court ruled Thursday, rejecting an attempt by skeptics of global warming to view the work of a prominent climate researcher during his years at the University of Virginia. The ruling is the latest turn in the FOIA request filed in 2011 by Del. Robert Marshall (R-Prince William) and the American Tradition Institute to obtain research and e-mails of former U-Va. professor Michael Mann..."
Weather-Related Blackouts Doubled Since 2003: Report. A ten-fold increase in major power outages between the mid-80s and 2012? Here's the introduction to a disturbing report, summarized at Climate Central: "Climate change is causing an increase in many types of extreme weather. Heat waves are hotter, heavy rain events are heavier, and winter storms have increased in both frequency and intensity. To date, these kinds of severe weather are among the leading causes of large-scale power outages in the United States. Climate change will increase the risk of more violent weather and more frequent damage to our electrical system, affecting hundreds of millions of people, and costing Americans and the economy tens of billions of dollars each year..."

The number of wildfires over 1,000 acres in size in the region stretching from Nebraska to California increased by a rate of seven fires a year from 1984 to 2011, according to a new study accepted for publication in Geophysical Research Letters, a journal published by the American Geophysical Union.
The total area these fires burned increased at a rate of nearly 90,000 acres a year – an area the size of Las Vegas, according to the study. Individually, the largest wildfires grew at a rate of 350 acres a year, the new research says.

U.S. GHG Emissions At Lowest Levels In 20 Years. The trends are encouraging in the USA, but any drop in carbon pollution here has been more than offset by spiking greenhouse gas emissions in China, India and other rapidly developing nations. Here's a clip from Climate Central: "U.S. greenhouse gas emissions declined 3.4 percent in 2012 from 2011, the Environmental Protection Agency announced Tuesday. Those emissions are down 10 percent from what they were in 2005, the EPA said, and are at their lowest levels since 1994. Most of the decline came from reductions in energy consumption, increased fuel efficiency of cars and other types of transportation, and a shift to natural gas from coal in fueling power plants, the EPA said in a statement..."

Analysis: How The Media Covered The U.N. Climate Reports In Three Charts. Are we losing interest or avoiding the subject altogether? Here's an excerpt from Media Matters: "...A Media Matters analysis found that the major print and television outlets devoted far less coverage to the most recent installment of the IPCC report than the first two reports by Working Group 1 (WG1) and Working Group 2 (WG2), which outlined the evidence that manmade climate change is happening and having largely negative impacts, respectively. The third report received only about a quarter (28 percent) of the amount of coverage given to the first report..."
