May Preview This Weekend - Dangerous Tornado Myths
So far it's the busiest year for tornadoes on record (reliable data goes back to 1950). Yesterday's outbreak was a violent reminder that the current pattern favors frequent outbreaks of large hail, damaging winds and tornadoes. At some point this atmospheric scuffle will migrate north. Peak season for Minnesota is May and June.
Now would be a good time to review a tornado action plan with your kids. The basement, under the stairs, is the safest place, not the southwest corner. Otherwise a small, windowless room on the ground floor, like a closet or bathroom. People have survived EF-5 tornadoes by crawling into their bathtubs.
Do NOT open windows to equalize air pressure. Avoid cars and mobile homes, which can become airborne at wind speeds over 100 mph.
The biggest myth: "tornadoes can't hit cities, or close-in suburbs, or cross rivers and lakes". Not true. Tornadoes pull in moisture and warmth from a 20-mile plus radius - a few high rise buildings or river won't slow it down.
Nothing but severe clear here into Saturday with a warming trend. If the sun stays out most of the day Saturday we should see 70s; average for late May. Model guidance hints at T-storms Sunday, then a cooler push early next week. Too warm for snow, too cool and dry for widespread severe outbreaks.
Compared to much of the USA we're getting off easy right now.
Signs of Spring: Phenology. The Minnesota DNR has a good post highlighting our fast-forward spring: "Spring 2017 began at a rapid pace in Minnesota. The songs of the first red-winged blackbirds of the season were heard in north Maplewood on Sunday, March 5, nine days earlier than the median date of March 14. This is the second earliest the musical birds have returned to the marshes of Maplewood. Winter made a bit of a comeback with below normal temperatures from March 9th to the 16th. In a rare occurrence, many lakes that were thawed in southern Minnesota refroze. In Maplewood, there was only one lake that was out before the cool down and this was tiny Spoon Lake just north of Highway 36. This lake thawed on March 6th, then refroze on March 10 with ice thick enough to support a basketball-sized rock, and lost its ice cover again on the 23rd. Warmer conditions returned for the last week of March and the progress of Spring restarted. The frost left the ground in Maplewood on March 29th. April began with above normal temperatures, but sunny days were still hard to come by. Phenology which is derived from the Greek word phaino meaning to show or appear, is the study of periodic plant and animal life cycle events that are influenced by environmental changes, especially seasonal variations in temperature and precipitation driven by weather and climate..."
Stormy Bookends. Relatively quiet weather is expected over the central USA today, with storms swirling on both coasts. The same intense area of low pressure that spawned tornadoes over the Deep South will push a pinwheel of heavy rain across the Mid Atlantic into New England today. Farther west enough cold air gets pulled into the circulation for a changeover to heavy wet snow. Meanwhile the next Pacific storm slops ashore, impacting northern California, Oregon and Washington state. 12 KM NAM: Tropicaltidbits.com.
Another West Coast Soaker. Over 2" of additional rain is forecast to soak northern California and parts of the Pacific Northwest in the coming days; as much as 2-3 feet of additional snow for the Cascades and Sierra Nevada.
- Establish a program to improve tornado warnings.
- Protect the Hurricane Forecast Improvement Program, whose funding was previously slashed.
- Develop a formal plan for weather research.
- Develop an annual report on the state of its weather models..."

Zika Poses Even Greater Risk for Birth Defects Than Was Previously Known, CDC Reports. Here's a clip from The Washington Post: "About 1 in 10 pregnant women infected with Zika in the United States last year had a baby or fetus with serious birth defects, according to a study released Tuesday that represents the largest and most comprehensive study of Zika’s consequences for pregnant women. Women infected during the first trimester of pregnancy had an even higher risk of birth defects, about 15 percent, according to the analysis by the Centers for Disease Control and Prevention. These estimates are higher than what U.S. health officials have previously reported and underscore the serious risk for birth defects posed by Zika virus infection during pregnancy. With warm weather, a new mosquito season and summer travel approaching, prevention is crucial to protecting the health of mothers and babies, said Anne Schuchat, the CDC's acting director..."

Walking 10 Minutes a Day Could Change Your Life. Here's a clip from nextavenue: "...Walking is also recommended as a great form of exercise. But there’s a difference between just walking and taking a mindfulness walk. “We often get so caught up in life and in our thoughts that we miss things,” Koerbel says. Our lives are filled with ordinary moments that we don’t pay attention to because we are rushing through them. “Being mindful is about stopping and pausing and taking notice of them,” says Koerbel. Notice, for example, how the air smells or how it feels when it hits your skin. Take a look at the colors around you — in the leaves of the trees, the grass or even the brown spots where the grass isn’t growing. Listen to the birds, the cars passing by, to the sounds of your particular environment..."

Trump Declares End to "War on Coal", but Utilities Aren't Listening. So says a story at Reuters: "...Reuters surveyed 32 utilities with operations in the 26 states that sued former President Barack Obama's administration to block its Clean Power Plan, the main target of Trump's executive order. The bulk of them have no plans to alter their multi-billion dollar, years-long shift away from coal, suggesting demand for the fuel will keep falling despite Trump's efforts. The utilities gave many reasons, mainly economic: Natural gas - coal’s top competitor - is cheap and abundant; solar and wind power costs are falling; state environmental laws remain in place; and Trump's regulatory rollback may not survive legal challenges...I’m not going to build new coal plants in today’s environment," said Ben Fowke, CEO of Xcel Energy, which operates in eight states and uses coal for about 36 percent of its electricity production. "And if I’m not going to build new ones, eventually there won’t be any...."

How We Know Today's Climate Change is Not Natural. Here's an excerpt from Earth Institute at Columbia University: "...Climate deniers offer a variety of bases for their skepticism without providing scientific evidence. The most effective thing that the climate denier community has done, however, is to spread the notion of uncertainty about climate change, and use it as an excuse not to take any action. “It’s been a very effective tactic,” said de Menocal, “in part because the scientific community spends a tremendous amount of effort quantifying that uncertainty. And so we make it plain as day that there are things we’re certain about, and things we’re uncertain about. There are places of debate that exist in the community. That’s the scientific process. … The deniers are not selling a new way of looking at the problem, they’re selling doubt, and it’s very easy to manufacture doubt.” “They are in total denial of the evidence that there is,” said Schmidt. “When I challenge them to produce evidence for their attributions, all I get is crickets. There’s no actual quantitative evidence that demonstrates anything. … Show me the data, show me your analysis...”

True Conservatives Should Worry About Climate Change. Here's an excerpt of an Op-Ed at The Charlotte Observer: "...To follow Mr. Loris’ recommendations will push the concentration of carbon dioxide above 400 ppm. We are now aware that these choices have consequences for us, for our children and for generations to come. The moral choice has been different over the last 30 years than it was for our grandparents. Mr. Loris cannot simply argue for a limited set of jobs helped by fossil fuels without also accepting the burden we now understand – such as rising sea levels, abnormal precipitation leading to droughts in some areas and flooding or mudslides in others. It is not a conservative value to ignore our impacts on those around us or on the economic conditions we leave for our kids. Thankfully, there are conservative voices speaking out on this issue. Fifteen House Republicans have joined the bipartisan House Climate Solutions Caucus to hold meaningful discussions on what can be done..."
