Severe Risk Friday – A “Plan B” Weekend Coming
I would like to publicly apologize for the weekend forecast. I have NOTHING to do with the weather – but I WILL be blamed when the sky turns foul and runny on Saturday. It’s inevitable.
Which begs the question: are you ‘weather-sensitive’? New research suggests that 15-20 percent of us are genetically hypersensitive to our surroundings. Are you easily overwhelmed by bright lights and noise? Do you startle easily? Extra-sensitive to caffeine? If so a dreary weekend may affect your moods more than most.
I wish I could prescribe an antibiotic of warm weekend sunshine, but another surge of cool air keeps us showery much of Saturday and Sunday with a stiff wind. Temperatures may not climb out of the 60s Saturday afternoon. The approach of this (rude, ill-timed) cool front may spark the first widespread severe T-storm outbreak of 2016 on Friday. The biggest risk is large hail and straight-line winds, but an isolated tornado can’t be ruled out.
That said, today will be stunning and summer heat returns next week; 90F by next Thursday. Wild weather swings?
Welcome to Minnesota!
Weather and Mood: Rainy With a Chance of Depression. Are you “weather-sensitive”? It would appear that there’s considerable data to suggest that some of us are more prone to ups and downs triggered by changes in the weather. Here’s an excerpt from the information referenced in today’s column at Everyday Health: “…Weather is going to affect you more if you are a highly-sensitive person, as defined by Elaine Aron, PhD, in her best-seller, The Highly Sensitive Person. If you answer yes to these and most of the questions on Aron’s website, you’re probably in the club, which holds 15 to 20 percent of human beings. Are you easily overwhelmed by bright lights and noise? Do you startle easily? Do other people’s moods influence you? Does caffeine have a great effect on you? Research has indicated that hypersensitive people are genetically different from folks who have a normal degree of sensitivity. This might explain why the rain or cold or heat affects some of us much more than others, and why some people would thrive in a humid, hot climate, while others would wilt. Your response to weather would depend on your sensitivity type…”
Severe Risk Friday. NOAA SPC has much of central and southern Minnesota and western Wisconsin in a slight risk of severe storms. The main threat will be large hail and straight-line winds, but a few isolated tornadoes can’t be ruled out tomorrow. Map: AerisWeather.
Future Radar. 4 KM NAM guidance shows a developing squall line Friday afternoon, capable of hail and damaging winds, with the heaviest rain bands sweeping across central Minnesota. Guidance: NOAA and AerisWeather.
Inch of Rain by Midnight Friday? Internal model ensembles are hinting at somme 1″+ rains for the metro area by Friday night and Saturday morning.
Locally Heavier Amounts. As is always the case with convection there will be big extremes in rainfall amounts across the state, NOAA models printing out some 2″+ amounts near Brainerd, Walker and Wadena by Saturday morning.
Cool Weekend – Heating Up Next Week. Temperatures may not climb much above 70F Saturday, but Sunday looks milder and sunnier (only a late-day instability shower or T-shower). 80s return in full force by the latter half of next week, according to ECMWF forecasts. Graphic: WeatherBell.
Texas’ Brazos River Surges to Century High, Houston Braces for Floods. Reuters has the very latest on a very serious situation playing out across metropolitan Houston – and much of Texas: “…Houston has activated its emergency operations center as forecasters warned of heavy rains and flooding. Emergency shelters were opened in the Houston area. Flooding around Houston in April left eight people dead and damaged some 1,500 homes. In the most recent floods, hundreds of people across the state have fled their homes. “It’s scary, we have never had anything like this before,” said Mary Hernandez of Richmond in metropolitan Houston, where evacuations were underway...”

This Is Why Parts of Texas Are Enduring Yet Another Torrential Spring. Angela Fritz has details at Capital Weather Gang: “Why does this keep happening? The atmosphere is all blocked up. High pressure is building over California, surrounded by areas of low pressure. It’s a very disrupted flow in which the jet stream becomes twisted and distorted and storms cannot pass through as quickly as they would otherwise. The high pressure acts like a rock in a stream — the flow gets blocked and storms have to pass around it. The low pressure acts to reinforce the high pressure, and the pattern can strengthen and last for weeks…”

What To Do If You’re Driving And Encounter a Flash Flood. Rule #1 – don’t drive through high water – it’s impossible to estimate water depth, especially at night. Only 2 feet of moving water can turn your vehicle into a boat, with tragic consequences. NOAA has it right: “Turn around, don’t drown.” Here’s an excerpt from Popular Mechanics: “…Getting swept away while inside your vehicle is extremely dangerous. Although it sounds counterintuitive, if you’re stuck inside your car, you’ll want to roll down your windows and allow water to enter your vehicle. You can escape from your vehicle through the window or, if that’s not possible, wait until the water pressure is equal on both sides of your door so it will open...”
Prime Time for Severe T-storms Approaching. Historically, June is the wettest, most severe month of the year in Minnesota, so it’s premature to let our guard down just yet. Here’s an excerpt of a story with good perspective from WXshift: “…Those atmospheric ingredients tend to come into play across the Southeast in March as warm, moist air flows up from the Gulf of Mexico and meets with cooler, drier air dropping down from the northwest. That’s why March is peak tornado season for that region, known as Dixie Alley. From there, the pattern spreads north and west toward the heart of Tornado Alley in the Central Plains. The statistical peak of tornado season is June 12, with the bullseye square over Kansas; the risk of severe weather then continues through the summer before eventually petering out in October as the seasons change...”

If You Build It They Will Come – Hurricanes, That Is. Meteorologist John Morales from Miami has a timely post at WXshift; here’s the intro: “In the classic baseball movie “Field of Dreams,” a baseball diamond was built in a cornfield. In what could be a disaster movie-in-production, Florida has built enough housing and infrastructure in the past decade to accommodate 2.5 million new residents. It’s clear that a lot of building has been going on in the Sunshine State lately. But not one has come! Not a single hurricane has reached Florida since major Hurricane Wilma in October 2005. When this year’s Atlantic hurricane season starts on June 1, it’ll mark a record 10 years, seven months and eight days since the last landfall…”

Republicans and Democrats Agree On At Least One Thing: Wildfires Are a Major Threat. Here’s the intro to a story at Grist: “A bipartisan group of U.S. senators is teaming up to do away with preordained spending caps on emergency fire recovery efforts as the American West braces for another wildfire season. Drier conditions, likely driven by climate change, have turned vast swaths of the continent into veritable tinderboxes; last summer, for example, five million acres of Alaska and 1.7 million acres across Washington, Oregon, and Idaho burned. “We need to call mega-fires what they are — disasters,” said Sen. Mike Crapo (R-Idaho), in a press release…” (Image credit: REUTERS/Noah Berger).
Why a Power Grid Attack is a Nightmare Scenario. Alarmist hype? I sure hope so. Here’s an excerpt from TheHill: “…While cybersecurity experts and industry executives describe such warnings as alarmist, intelligence officials say people underestimate how destructive a power outage can be. The most damaging kind of attack, specialists say, would be carefully coordinated to strike multiple power stations. If hackers were to knock out 100 strategically chosen generators in the Northeast, for example, the damaged power grid would quickly overload, causing a cascade of secondary outages across multiple states. While some areas could recover quickly, others might be without power for weeks. The scenario isn’t completely hypothetical. Lawmakers and government officials got a preview in 2003, when a blackout spread from the coastal Northeast into the Midwest and Canada...” (File photo: AP).
Rising Seas Could Swamp Crucial Infrastructure. Markeplace takes a look at the implications of a 2 foot rise vs. a 6 foot rise; here’s an excerpt: “…Nationwide, there is little coordinated planning or funding to deal with the threat posed to public infrastructure and private real estate by climate change and rising sea levels. “There are thousands of hazardous waste sites, chemical facilities that are on low-lying industrial land around the country,” said Ben Strauss at Climate Central. “And that is a huge concern.” Strauss is vice president for sea level and climate impacts at Climate Central, which has developed online mapping tools to show the potential effects of temperature and sea-level rise over the next century. Based on a projection of 2 feet in sea-level rise by 2100, Strauss said, “it is reasonable to imagine defending most coastal places with a couple of exceptions: some barrier islands, South Florida, parts of Louisiana. But with 6 feet, it becomes pretty much impossible to imagine—we see severe challenges to places like New York City or Boston…”

2015: A Record Year for Renewables. Reuters has the facts and figures: “A record amount of renewable power capacity was installed worldwide last year as solar and wind costs fell, becoming more competitive with fossil fuels, research by renewables policy organisation REN21 showed on Tuesday. New installations of renewable power generation capacity (including hydropower) rose to 1,848.5 gigawatts (GW) globally in 2015, an increase of 147.2 GW from the previous year, Paris-based REN21’s annual renewables global status report showed. This is the largest ever annual increase in installed capacity and was mainly driven by renewables becoming more cost-competitive with oil, coal and gas in many markets and an increase in government policies to support the growth of clean energy, it added…” (File photo: MN.gov).
The Walled World of Work. The Economist has an article with some eye-opening statistics; here’s an excerpt that made me do a double-take: “Over the next decade more than 1 billion young people will enter the global labour market, and only 40% will be working in jobs that currently exist, estimates the World Bank. Some 90% of new jobs are created by the private sector. The best thing for job creation is economic growth, so policies that promote growth are particularly good for the young. Removing regulatory barriers can also boost job creation…”
Mary Meeker’s 2016 Internet Trends Report. Recode has a link to the full 213 slide PPT; here’s an excerpt that caught my eye: “…The home screen has acted as the de facto portal on mobile devices since the arrival of the iPhone and even before. Messaging apps, with context and time, have a chance to rival the home screen as the go-to place for interaction…”
A Shrine to Licorice. If you’re into that kind of thing. Here’s a clip from Atlas Obscura: “The Shrine hovers over 500 varieties of authentic licorice from all over the world including imports from Holland, Finland, Sweden and Germany with displays that identify the country of origin by tiny country flag. There are brightly colored packages and tins of soft and hard licorices, licorices filled with blueberry, mango and pomegranate, sweet and salty licorices, super hot and gluten free licorices…”

The “Temperature Spiral” Has an Update. It’s Not Pretty. This is one of the better visualizations I’ve ever seen about the warming underway – here’s an update from Climate Central: “…Like a lot of people, I found Ed Hawkins’ temperature animation very compelling because it details observed warming from 1850 to present in a novel way,” U.S. Geological Survey scientist Jay Alder said. “His graphic sets the context for looking at projections from climate models.” So Alder used climate projections and stretched the spiral to its logical conclusion in 2100 when most climate model projections end. Using our current carbon emissions trends, it shows that things could get out of hand pretty quickly...”

Houston Flooding is a Perfect Storm of Climate Change and Bad Urban Planning. Suddenly the “no zoning!” provisions seem like more of a bug than a feature, according to Grist: “…One likely cause,” Texas’ state climatologist John Nielsen-Gammon tells Grist, “is the increase in ocean temperatures from the Gulf of Mexico and tropical Atlantic. That determines how much moisture is in the atmosphere.” As temperatures increase, so does rainfall. But it’s not just the rainfall that is endangering Houston’s citizens — it’s also ecologically irresponsible development. Houston is the only major American city without formal zoning laws. As a result, developers have been free to pave over huge swaths of valuable wetlands that absorb runoff…”

Spike in Alaska Wildfires is Worsening Global Warming, U.S. Says. Here’s the intro to a story at The Guardian: “The devastating rise in Alaska’s wildfires is making global warming even worse than scientists expected, US government researchers said on Wednesday. The sharp spike in Alaska’s wildfires, where more than 5 million acres burned last year, are destroying a main buffer against climate change: the carbon-rich boreal forests, tundra and permafrost that have served as an enormous carbon sink. Northern wildfires must now be recognised as a significant driver of climate change – and not just a side-effect, according to the report from the US Geological Survey…”

Climate Change Threatens to Turn Prairies into Dust Bowl. Canada’s Chronicle Herald has the story; here’s the intro: “Canada’s breadbasket could become a new Dust Bowl as climate change tightens its grip, warns a Dalhousie University food expert. Dr. Sylvain Charlebois, a specialist in food distribution and policy, said that Canada’s Prairies are expected to be the region most vulnerable to climate change in the world. He cited a recent Manitoba study that predicts Winnipeg will likely see the number of 30 degree-plus days per year rise from 11 to 46 in the next 50 years. The report also warns that those most vulnerable to climate change include not only farmers but low-income people and First Nations communities, who will struggle to cope with higher food prices…”

15 Photos of Devastating Floods Show What The Future of Europe Could Look Like. Here’s a story excerpt from Huffington Post: “…The devastation caused by the flooding shows the vulnerabilities that even wealthy countries face as global warming causes the climate to change and weather to become more extreme. “We cannot predict climate on a local scale 10 years ahead or even further, but we can put a lot more effort on extracting the information on what could be happening in that far-away abstract future by looking at the extremes that happen today,” Bart van den Hurk, a doctor at the Royal Netherlands Meteorological Institute, said in a report published last week by the European Commission. A study released in March 2014 found that the frequency of severe flooding across Europe is expected to double by 2050. The annual economic costs from that flood will go up nearly fivefold, the study found…”

If Climate Scientists Are In It For The Money, They’re Doing It Wrong. Here’s an excerpt from Ars Technica: “…It’s also worth pointing out what they get that money for, as exemplified by a fairly typical program announcement for NSF grants. It calls for studies of past climate change and its impact on the weather—pretty typical stuff. This sort of research could support the current consensus view. But it just as easily might not. It’s impossible to tell before the work’s done. And that’s true for pretty much every scientific funding opportunity—you can’t dictate the results in advance. So, even if the granting process were biased (and there’s been no indication that it is), there is no way for it to prevent people from obtaining data that poses problems for the current consensus…”
Record-Breaking Heavy Rainfall Events Increased Under Global Warming. Professional climate deniers will tell you otherwise, but the data suggests an increase in extreme rainfall events, worldwide. Here’s an excerpt from PIK Research Portal: “Heavy rainfall events setting ever new records have been increasing strikingly in the past thirty years. While before 1980, multi-decadal fluctuations in extreme rainfall events are explained by natural variability, a team of scientists of the Potsdam Institute for Climate Impact Research detected a clear upward trend in the past few decades towards more unprecedented daily rainfall events. They find the worldwide increase to be consistent with rising global temperatures which are caused by greenhouse-gas emissions from burning fossil fuels. Short-term torrential rains can lead to high-impact floodings…”
