Nothing to Whine About: Welcome Rain Today – 70s Return Next Week

55 F. high temperature in the Twin Cities Thursday.
62 F. average high on April 23.
47 F. high on April 23, 2014.

April 23, 1990: A record of 88 degrees is set at Redwood Falls

Sputtering Spring

Oh stop your whining. Yes, you. I know it’s buried somewhere in the Constitution – or maybe the Bill of Rights? I should have paid attention in history class. Yes, it’s our God-given right to honk, bellow and bray about the vicissitudes of the weather. It’s just all SO unfair!

A dollop of perspective is in order. April 2015 is still running 3.5F warmer than average, to date. We’ve picked up .3 inches of snow this month. That compares to 7 inches in April, 2014, and a whopping 21.8 inches of snowy fun in April, 1983. That was my first full month living at MSP. I remember wondering what parallel universe I had tumbled into.

So it hasn’t been that rough a spring, all things considered. Moisture has been sparse though, lake water levels are down; all but far southeast Minnesota is in moderate drought. A 3-day soaking qualifies as “good weather” this year.

NOAA’s NAM model prints out .76 inches of rain Friday night but I think that may be generous; once again the brunt of the rain is forecast to pinwheeling south of Minnesota. Long-range ECMWF guidance shows a string of 70s next week, even a shot at 80F. It will feel like spring again next week.

In today’s blog: dual polarization Doppler at 152 National Weather Service sites is so sensitive it can see the “debris ball” of a tornado on the ground. That should mean fewer false alarms.


Moderate Drought. All but far southeastern Minnesota is now in an extended (deepening) drought, as the biggest, wettest storms continue to track south of Minnesota. I’m still hoping for a shift in the pattern, one that brings a parade of sloppy storms into the Upper Midwest. That could still happen but it’s not imminent.

Late Evening Tornado Outbreak? AerisWeather’s TPI, Tornado Potential Index, shows an enhanced risk of tornadic supercell thunderstorms from Dallas to Tulsa and Wichita. There’s a good chance SPC may upgrade the enhanced risk to moderate risk, which is a tripwire of sorts, suggesting at least a few large, long-track and damaging tornadoes.


Late April Sledding. NASA’s high-resolution MODIS satellite imagery shows snow on the ground over the Minnesota Arrowhead and BWCA; significant snow for much of Ontario. You can clearly make out the lake-effect streaks of snow, especially downwind of Lake Superior.


A Long, Cool Drink? NOAA model guidance shows some .50″+ rainfall amounts setting up north of St. Cloud and south of the Twin Cities and Eau Claire, the heaviest amounts of rain reaching Iowa and Illinois where some 1-3″ rains may trigger flash flooding. Source: AerisWeather Enterprise.


Warming Trend. Today looks cool and damp and Saturday won’t win any awards for beauty and splendor. But things start to go right again Sunday, with a streak of 60s and 70s next week; 80F not entirely out of the question by the end of next week. Source: Weatherspark.


First 80s of 2015. Models are in fairly tight agreement, showing a steady warming trend into late April and the first week of May. A few models shows highs near 80F from April 30 to about May 3. Source: AerisWeather Enterprise.


How Warm Weather Influences our Mood. Yes, warm fronts can be good for your state of mind. There’s even science to back up (the obvious!) Here’s an excerpt of a good summary at Huffington Post: “…The gold standard on this subject is a 2004 University of Michigan study that found people who spent at least 30 minutes outside in pleasant weather — either by taking a trip to warmer climates in the winter months or by taking advantage of a newly warm spring day in the park — had happier moods. And in corroborating research, a 2014 UM study found that being outside could lead to a better mindset and reduced stress…”


What If April 9th Tornado Had Taken A Different Path? Large cities have been particularly lucky when it comes to direct strikes from major tornadoes. So argues the author of this good post at Northern Illinois University Newsroom: “…And had it been closer to Chicago, the number of homes and people affected would have been immense. People have a false sense that tornadoes only happen in rural settings, but nothing could be further from truth,” he added. As evidence, he points to Minneapolis, Atlanta, Springfield, Mass., Huntsville, Ala. and Raleigh, N.C. Just within the last decade, tornadoes have struck downtown areas in those cities. In Illinois, the 1967 Oak Lawn tornado and the 1990 Plainfield tornado are reminders that the Chicago metropolitan region is not immune to tornado threats…”

Radar Upgrade Has “Changed The Way We Do Business” At Weather Service. Al.com has an interesting article focusing on the advantages of dual-polarization Doppler radar, and for the first time, the ability to see debris lofted into the air by large tornadoes. Here’s an excerpt: “…Dual-pol radar can help meteorologists better identify when a tornado has touched down. It’s even more useful at night, when storm spotting becomes next to impossible. “It can tell us when a tornado is on the ground and that debris is being cast high into the air,” said Jeffrey Medlin, the meteorologist in charge at the National Weather Service office in Mobile. “We have several different data sets we can look at within the dual pol and see that…”

100-Year Hurricane Could Cost $250 Billion If It Hit Miami. At some point our luck will run out. If not Miami, Tampa, Houston, New York or Boston. Here’s the intro to a story at Miami New Times: “Hurricane season 2015 starts in just a few weeks and so far, most experts are forecasting another sleepy storm period in the Atlantic. But another study out this week makes it clear that it would only take one monster ‘cane to wreak an insane amount of damage in booming South Florida. A new study released by the disaster modeling experts at the Karen Clark Company estimates that if a major hurricane, with a 1-in-100 chance of occurring in a given year, were to hit downtown Miami the losses would eclipse more than $250 billion in damage...”


Where People Go To Check The Weather. Young people, millenials specifically, aren’t consuming weather information the way their parents do. It’s all about mobility. Here’s an excerpt of an interesting read at FiveThirtyEight: “…Because I’m 24, I either don’t bother checking the weather or just use the default app on my phone. I assumed everyone else was like me in this regard. I was wrong. I couldn’t find data on this, so I asked SurveyMonkey Audience to run a simple survey. It ran April 6-10 and had 938 respondents. It asked two main questions: How do you check the weather? And, do you check a weather report every day?…”


Mission Possible. Can a 64-year-old guy with heart disease, emphysema (COPD), and missing half a lung, succeed at twelve of the most iconic climbs in America?  “Phil Huston climbed mountains, rock cliffs and ice walls in 5 countries. He climbed Mount Rainier 12 times; the last ascent just 3 months after losing half of his lung to cancer. “The Climb for Clear Lungs Adventure” proves that even the worst health crises can be overcome. Let’s show how strong older athletes really are!  35 days. 12 climbs. 7 destinations. 18,000 vertical feet. Goal: Promoting screening for millions with undiagnosed lung diseases.”

Clear Lungs Adventure: Sunday, 4/26 at 3:30, Room 104 Hanson Hall, University of MN, West Bank.

* If you’ve smoked at least 100 cigarettes over the course of your life you are at increased risk of COPD. Phil is a dear friend of mine (we worked together at WLOL-FM). He isn’t letting COPD slow him down, but his mission is to raise awareness among the general population. Many people have COPD and they don’t even realize it yet. Take the screening test from the COPD Foundation; it takes a minute or two.


It’s Not The 1% Controlling Politics. It’s The 0.01 Percent. Corporations are people, and my dog, Leo, is a space alien. God help us. Here’s a clip from a story at Mother Jones: “…In other words, about 125 Americans* control more than 40 percent of election contributions. Notably, between 2010 and 2012, the total share of giving by these donors jumped more than 10 percentage points. That shift is likely the direct result of the Supreme Court’s 2010 Citizens United ruling, which struck down decades of fundraising limits and kicked off the super-PAC era. And this data only includes publicly disclosed donations, not dark money, which almost certainly means that the megadonors’ actual share of total political spending is even higher…”


Italian Company Hopes To Market Synthetic Eyeballs. The bionic man may not be that far off, after all. Here’s an excerpt of a fascinatingly creepy post at Gizmag: “Imagine being able to see in black and white or with an Instagram-like filter, or to have what you see through your eyes transmitted wirelessly, simply by swallowing a pill. Or imagine having vision so sharp and accurate that your visual acuity is on par with the most sight-adept people in the world. Italian research studio Mhox hopes to one day make this a reality with its EYE concept, which would offer 3D bioprinted eyes that replace your existing eyeballs…”

Climate Stories…

What Do Volcanic Eruptions Mean For The Climate? Carbon Brief does a good job summarizing the potential impact of the new volcano roaring to life in Chile; here’s an excerpt: “…Volcanic eruptions can affect climate in  two main ways. First, they release the greenhouse gas carbon dioxide, contributing to warming of the atmosphere. But the effect is very small. Emissions from volcanoes since 1750 are  thought to be at least 100 times smaller than those from fossil fuel burning. Second, sulphur dioxide contained in the ash cloud can produce a cooling effect, explains Prof Jim McQuaid, professor of atmospheric composition at the University of Leeds…”

Changes in Water Vapor and Clouds are Amplifying Global Warming. The Guardian has the story – here’s a snippet: “… If the cooling effect gets smaller, it means the Earth will warm more than expected. If the cooling effect of clouds gets bigger, it means the Earth will warm less than expected.
What the present paper shows is that future changes to clouds will cause slightly more warming. Scientists describe clouds as a “positive feedback” on global warming. This finding is consistent with the work of Dr. Andrew Dessler. He had published work here and here showing changes in clouds are making the Earth warm more than otherwise expected

Conservatives Don’t Think Global Warming Will Happen In Their Lifetimes. Not all conservatives, but a significant percentage. Which is ironic, because it’s happening now – we’re already observing symptoms. And conservatives in Europe and even China are now acknowledging the trends. Here’s the intro to a story at Politico: “Everyone except conservative Republicans seems to agree that global warming will happen in their lifetime, according to a new Gallup survey released Wednesday, just in time for Earth Day. Fewer than four in 10 self-identified conservative Republicans — 37 percent — think that global warming will occur in their lifetime, while 19 percent believe it will affect future generations…”


It’s Time To Begin Bracing For Effects of Climate Change. The Register-Guard in Eugene, Oregon has the Op-Ed; here’s an excerpt that caught my eye: “…However, in what might turn out to be a mistake of epic proportions, there have been no efforts to teach the skills that people and groups will need to cope psychologically, emotionally and spiritually with the increased frequency and intensity of extreme weather events and the toxic stress associated with climate disruption. Research has linked climate impacts with debilitating anxiety, depression, moral distress, compassion fatigue and post-traumatic stress disorder. Mounting psychosocial troubles have been identified, including interpersonal aggression, extremism, crime and violence. The Pentagon has connected climate disruption to more terrorism and war…”

Obama In Everglades: Threats from Climate Change “Can’t Be Edited Out” of Conversation. Here’s a snippet from a Miami Herald story: “…Obama also took a jab at Republican Gov. Rick Scott, who prohibited state staff from using the term “climate change,” according to several former employees and academics. Scott has said no such ban exists. “Climate change can no longer be denied. It can’t be edited out. It can’t be omitted from the conversation,” Obama said, without naming the governor...”
