Surge of Stinking Hot Weather Next Week

"I look forward to being older, when what you look like becomes less and less an issue, and what you ARE is the point," said actress Susan Sarandon.

Dr. Anthony Fauci gives me hope for productive life after middle age. He's 79, and along with Minnesota's Michael Osterholm, arguably the leading epidemiologists on the planet.

Then again, age has always correlated with wisdom and and perspective. Benjamin Franklin was 70 when he signed the Declaration of Independence. Nelson Mandela was 75 when elected president of South Africa. Mother Theresa received a Nobel Peace Prize at age 69 for her charitable work. John Glenn was 77 when he piloted the Space Shuttle. Seniors have much to contribute, and always will.

Showers arrive today, with more puddles Saturday, before we salvage some lukewarm sunshine on Sunday - the nicer day of the weekend to putter in the yard.

Only in Minnesota can one go from frost to 80s in the span of a week. Next week should be "stinking-hot", with 3 days of 80s and high humidity. Another light-switch summer?

80s Next Week. It seems like divine, cosmix, meteorological justice of sorts. Slush and frost one week, 80s the following week as a flailing atmosphere tries to compensate. I see 3 or 4 days in the 80s next week. Many of us are ready to make up for lost time. Graphic sequence above: Praedictix and AerisWeather.

Flash of Summer. Our on-again, off-again spring gives way to a preview of summer next week with a few days in the 80s. Both ECMWF (top) and GFS (bottom) hint at 90F by Wednesday of next week. We'll see. MSP Meteograms: WeatherBell.


Trending Warmer Than Average. In spite of a few (minor) cool frontal passages it looks like the last half of May will end on a warmer than average note for much of the USA; baking heat for much of the west and south.

The Coronavirus Pandemic and Loss of Aircraft Data are Taking a Toll of Weather Forecasting. The models are wonkier than usual, and there may be a good reason. Here's a clip from Capital Weather Gang: "...According to the WMO, when operating at full capacity, the global aircraft-based observing system produces over 800,000 weather observations per day using planes from 43 airlines and several thousand aircraft in all. In the U.S., as of April 20, “the daily output of meteorological data from U.S. commercial aircraft has decreased to approximately one quarter of normal levels,” according to NOAA spokesman Chris Vaccaro. When at full capacity, aircraft soundings, as such data is known, dwarf the volume of the twice-a-day weather balloons launched from 900 weather stations around the world. In a typical year in the United States, more than 3,500 commercial aircraft provide more than 250 million observations per year, according to a NOAA statement (not every aircraft in the sky is part of the observing network)..."

Warm Sea Surface Temperatures Make Above-Average Hurricane Season Likely. A story at news4jax.com in Jacksonville, Florida caught my eye: "...Right now the warm waters in the tropical Atlantic are running a bit longer than normal about quarter to half a degree Celsius or about half a degree to one degree Fahrenheit,” Klotzbach says. Sea surface temperatures are one of the ingredients needed to fuel hurricanes. The warmer the ocean, the more fuel available for the storms to tap into. "The current Atlantic sea surface temperature setup is consistent with active Atlantic hurricane seasons," says Klotzbach. "With the notable exception of the far North Atlantic, which remains somewhat cooler than normal." "Since tropical systems feed off of warm sea surface temperatures, this could certainly lead to a more active 2020 Atlantic hurricane season," Ward says..."
With Increasing Storms, Atlantic Hurricane Season Needs to Expand and Begin on May 15. The authors at Capital Weather Gang make a compelling case, based on data and trends: "...These tests show the current definition of hurricane season encompasses less than its intended 97 percent of storm development cases in the modern era. The June 1 to Nov. 30 period captures 96.2 percent of total tropical or subtropical formation events over 1971 to 2018, meaning 3.8 percent of storms develop in the purported offseason. A hurricane season beginning on May 15 would miss 2.6 percent of Atlantic genesis cases, cutting offseason systems by a third. Even worse, June 1 to Nov. 30 is particularly late-shifted with respect to impacts, missing 3.1 percent of U.S. landfalls with wind speeds exceeding 39 mph (34 knots). In contrast, a six-month hurricane season beginning on May 23 would miss just 1.2 percent of landfalls, and a May 15 to Nov. 30 season would capture all but one out of 162 U.S. storms since 1971..."

Sudden Pattern Change On The Way. Here's the intro to a good explainer at Capital Weather Gang: "After a weeks-long stretch of chilly weather in the East and scorching warmth across the West, the stubborn pattern dominating the nation’s weather is just days away from easing its harsh grip on the country. A dramatic warm-up is in store for cold-weary residents in the Northeast, where temperatures up to 30 degrees below normal and even snow made the start of May feel more like March. Meanwhile, the unbearable heat sizzling the Southwest has begun to ease. Monday could be the first day in a week that Phoenix doesn’t hit 100 degrees, a welcome relief from the brutal scorcher that has brought summertime temperatures a month ahead of schedule. The dramatic changes come as a weather pattern shift teeters the United States’ meteorological seesaw in the other direction..."

Pockets of Drought Emerging. It may my meds, but I'm leaning toward drought emerging by the end of summer for parts of the Upper Midwest. Just a hunch, based on how the patterns seem to be setting up. The U.S. Drought Monitor has an update: "..The Corn Belt remains drought-free due to long-term precipitation surpluses, favorable soil moisture, and a cool start to spring (30-day temperatures averaging 2 to 4 degrees F below normal). A small area of abnormal dryness (D0) was decreased this week due to recent rainfall. The largest 30-day precipitation deficits (around 3 inches) exist across northern Iowa..."


New Weather Alerting Technologies Will Save Lives. I wrote a post for Medium, focusing on some of the new and novel ways of receiving severe weather notifications; here's an excerpt: "...Traditional media can provide what your favorite weather app cannot: perspective, context and analysis. Meteorologists add value in real time and help to highlight time-sensitive information that can help to secure property, even save your life. The truth: flesh and blood meteorologists still add value you won’t get from automated alerts. Managing a continuous firehose of information and updates is daunting, for everyone. Social media gossip and speculation runs rampant before a major storm outbreak. Combine that with shorter attention spans, and a spray of notifications, headlines and advertisements, and it can be difficult separating signal from the noise. That is where new technologies come in, offering the rough equivalent of a digital tap on the shoulder. Pay attention. This is important..."


Bill Gates Has Regrets. Could-have, should-have, would-have. Here's an excerpt from a Wall Street Journal (paywall) story: "...In March 2015, Mr. Gates warned in a widely watched TED Talk that an infectious disease pandemic posed a greater threat to the world than a nuclear war because nations have built so few defenses. He called for an international warning-and-response system with mobile units of medical personnel, rapid diagnostics, drug stockpiles and technologies to produce vaccines in months. “An epidemic is one of the few catastrophes that could set the world back drastically in the next few decades,” he wrote that month in the New England Journal of Medicine. Mr. Gates joined other global-health experts calling for better public-health defenses. “In no way was I a lone voice,” he said. “The one thing that’s unique about my voice, though, is that I haven’t spent my life in infectious diseases...”

There is No Evidence That Voting by Mail Gives One Party an Advantage. Here's a clip from FiveThirtyEight: "...Numerous studies have arrived at the same conclusion: Voting by mail doesn’t provide any clear partisan advantage. In fact, as states have expanded their use of mailed ballots over the last decade — including five states that conduct all-mail elections by default — both parties have enjoyed a small but equal increase in turnout. In short: voting by mail is more convenient for some voters but more difficult for others, and these conflicting factors appear to cancel each other out, dampening any partisan advantage. Moreover, the vast majority of nonvoters don’t participate not because it’s too inconvenient to vote, but because voting isn’t a habit for them. Maybe they don’t care about politics, maybe they don’t think their vote matters, maybe they don’t like any of the candidates, or maybe it’s some combination of all of the above..."


Why Time Feels So Weird Right Now. Doesn't it? Here's an excerpt of a plausible explainer at Vox: "...So what we call our internal clock is actually a whole bunch of internal clocks. We’ve got multiple systems, all of them influencing the subjective perception of time. We’ve got systems just for regulating our bodily functions like our sleep cycle. We’re constantly interpreting and synchronizing multiple sensory modalities — our auditory information has to be integrated into and synchronized with what we’re seeing visually, for example. We’re constantly switching our attention and regulating attention. We’re constantly integrating memories and our anticipations into making plans and performing critical actions. So there’s a lot of stuff going on all at the same time that all have to do with our internal sense of the passage of time..."

Climate Stories...

Coronavirus Could Worsen Death Toll of Summer Heat Waves, Health Officials Warn. The Los Angeles Times reports: "High temperatures have rolled through the Southwest unusually early this year, scorching Phoenix and Las Vegas and sending droves of quarantine-weary Southern Californians to the beaches. Even before the outbreak, the hottest parts of the country were struggling to protect their residents from summer weather that, fueled by global warming, has become increasingly dangerous. Now the COVID-19 epidemic has presented them with an added crisis — the possibility of millions of people self-isolating in homes and apartments they can’t keep cool. This is an especially worrying possibility for the elderly and people in poor neighborhoods, where residents are more likely to live in older, less energy-efficient homes and less likely to have air conditioners..."


Missouri River Basin Drought Worst Since Charlemagne: Climate Nexus has links and headlines: "Human-caused climate change caused the Upper MIssouri River Basin to be drier between 2000-2010 than at any point in the last 1,200 years, according to new research. A study published Monday in the Proceedings of the National Academy of Sciences found the drought of the 2000s mirrored the “megadroughts” of the last 500 years, but was made worse by climate change’s impact on Rocky Mountain snowpack, a crucial source of water for the river that is very sensitive to warming temperatures. Scientists used tree ring data to measure annual stream flow since 800 A.D. Climate scientists expect climate change to cause more and worse droughts in the future caused with significant repercussions for the region and beyond. “We’ve designed our agriculture and infrastructure around expectations that this water [from snow melt] will be provided at a certain pace over a certain part of the year,” Erika Wise, a co-author of the study, told the Washington Post."

Big Oil Earnings Battered by Virus, But Worst is Yet to Come. Bloomberg has the story: "Big Oil emerged from first-quarter earnings battered and bruised, but things are only going to get uglier. Major oil and gas producers from Norway to the U.S. saw profit plunge in the opening three months of the year. Exxon Mobil Corp. reported its first loss in over 30 years, Royal Dutch Shell Plc cut its dividend for the first time since the Second World War. And that was only the result of the initial spread of the coronavirus. Things have got even worse since as a global pandemic caused an unprecedented oil-market slump. There are some signs of recovery on the horizon, but companies were united in their warnings that the current quarter will be tougher than the first..."


Fact Check: The Coronavirus Pandemic Isn't Slowing Climate Change. USA TODAY explains: "With the coronavirus pandemic shutting down most global activity, a consequent crash in global carbon emissions has been widely reported. While analysts agree the historic lockdowns will significantly lower emissions, some environmentalists argue the drop is nowhere near enough. “Hey so it turns out that the people of earth accidentally did a global experiment to see if every individual could course correct climate change through mass personal change of habits, and it turns out, no! We can't!,” a Facebook post shared more than 4,000 times reads. The post shares a screenshot of another post that links to a Scientific American article with the chatter, "Despite all the 'natural is healing' commentary global CO2 emissions have not considerably declined during the pandemic..."

Climate Change Deniers Take On Coronavirus: Climate Nexus has headlines and links: "Climate change deniers are using tactics honed over decades of undermining climate action to spread conspiracy theories over official COVID-19 death counts, the New York Times reports. The Times tracks the ways in which many groups allied with the Trump administration, including many historically funded by tobacco and oil companies to question science, are using tactics similar to those they have used to sow doubt over climate science to inflate coronavirus rumors. In one instance, a claim that the virus’s death toll was being deliberately inflated traveled from a MN state senator, who made the rounds on conspiracy-oriented programs like Infowars, all the way to the president’s Twitter feed. “We don’t have perfect information,” James Taylor of the Heartland Institute, which has long questioned established climate science, told the Times. “The coronavirus models’ failure to make accurate predictions to this point should be instructive when we are told to blindly accept certain climate models.” (New York TImes)


Climate Change in Northern Climes. Cosmos Magazine connects the dots: "...Lakes and peatlands – spongy bogs and fens – make up the remainder of the boreal landscape. Peatlands store vast amounts of water and carbon in layers of living and dead moss and serve as natural firebreaks as long as they remain wet. Peatland mosses are not vascular plants, so as warming continues, they are more prone to drying out, the researchers say. Unlike forests, they have no active mechanism to protect themselves from losing water to the atmosphere. Dehydration exposes their dense carbon stores to accelerated decomposition, turning them from firebreaks into fire propagators – and bigger, more intense fires that can release vast amounts of carbon into the atmosphere, accelerating global warming..."
