Significant Severe Threat Later Today (near 80 into Thursday)

63 F. high yesterday at MSP International Airport (67 at Eden Prairie).
65 F. average high for April 30.
60 F. high on April 30, 2011.
Trace of rain yesterday in the metro area.

Severe storms likely later today, affecting less than 1% of the state. Damaging straight-line winds, large hail and a few tornadoes can't be ruled out. Stay alert, make sure you have a NOAA Weather Radio, and make sure you have an adequate shelter nearby.

4-9 pm. Time when severe storms are most likely in and near the MSP metro area.

Multiple Safety Nets. The more sources of severe storm information, the better:

NOAA Weather Radio. The only device that will alert you of a late-night tornado in your county.
TV, radio. Check batteries. Make sure you have a working flashlight in case power goes out.
Internet/E-mail. Monitor startribune.com for updates throughout the day. Check the latest videos for more info.
Smartphone apps. Many iPhone and Android apps can display Doppler and nearby watches/warnings.
Sirens (outdoor use only). Remember, the sirens were never meant to be heard indoors.

Today's Severe Storm Risk. Here is the latest overview from NOAA SPC, the Storm Prediction Center, showing a broad area of elevated risk from Omaha and Sioux City to Des Moines, Sioux Falls, the Twin Cities, Brainerd, St. Cloud and Duluth, and the western half of Wisconsin.

Severe Storm Probabilities. A 30% risk within the red hatched area means a nearly 1 in 3 chance of severe weather (58 mph+ winds and/or 1" diameter hail) within 25 miles of any town in the threat area. Translation: a good chance of severe storm watches and warnings - I wouldn't be at all surprised to see a few tornado watches issued for central and southern Minnesota later today. Stay alert and stay tuned. Map: SPC.

EHI. The energy-helicity index valid 7 pm this evening shows the greatest risk of tornadoes over the Oklahoma-Kansas border, but EHI values are very high over eastern Minnesota. EHI is a parameter that combines helicity (wind shear) with instability to show one number. This 0-3000 meter EHI index is courtesy of twisterdata.com.

Potential Growing For Damaging Winds Later Today. I want to stress that most of us will not experience damaging winds, but the fact that winds are forecast to gust close to 50 mph. this evening leads me to believe that we may see a squall line with (isolated) reports of 70-90 mph. winds. Most of us will experience straight-line winds, but a few isolated tornadoes can't be ruled out. Graphic: University of Iowa meteorology department.

Tornado Safety: here is some good information courtesy of FEMA's ready.gov:

If you are in:	Then:
A structure (e.g. residence, small building, school, nursing home, hospital, factory, shopping center, high-rise building)	Go to a pre-designated shelter area such as a safe room, basement, storm cellar, or the lowest building level. If there is no basement, go to the center of an interior room on the lowest level (closet, interior hallway) away from corners, windows, doors, and outside walls. Put as many walls as possible between you and the outside. Get under a sturdy table and use your arms to protect your head and neck. In a high-rise building, go to a small interior room or hallway on the lowest floor possible. Put on sturdy shoes. Do not open windows.
A trailer or mobile home	Get out immediately and go to the lowest floor of a sturdy, nearby building or a storm shelter. Mobile homes, even if tied down, offer little protection from tornadoes.
The outside with no shelter	Immediately get into a vehicle, buckle your seat belt and try to drive to the closest sturdy shelter. If your vehicle is hit by flying debris while you are driving, pull over and park. Stay in the car with the seat belt on. Put your head down below the windows; cover your head with your hands and a blanket, coat or other cushion if possible. If you can safely get noticeably lower than the level of the roadway, leave your car and lie in that area, covering your head with your hands Do not get under an overpass or bridge. You are safer in a low, flat location. Never try to outrun a tornado in urban or congested areas in a car or truck. Instead, leave the vehicle immediately for safe shelter. Watch out for flying debris. Flying debris from tornadoes causes most fatalities and injuries.

Tornado Preparedness. From CDC, the Center for Disease Control and Prevention: "Take a few minutes with your family to develop a tornado emergency plan. Sketch a floor plan of where you live, or walk through each room and discuss where and how to seek shelter."

• Show a second way to exit from each room or area. If you need special equipment, such as a rope ladder, mark where it is located.

• Make sure everyone understands the siren warning system, if there's such a system in your area.

• Mark where your first-aid kit and fire extinguishers are located.

• Mark where the utility switches or valves are located so they can be turned off--if time permits--in an emergency.

• Teach your family how to administer basic first aid, how to use a fire extinguisher, and how and when to turn off water, gas, and electricity in your home.

• Learn the emergency dismissal policy for your child's school.

• Make sure your children know--
  • What a tornado is
  • What tornado watches and warnings are
  • What county or parish they live in (warnings are issued by county or parish)
  • How to take shelter, whether at home or at school.

Tornado Tip-Offs. I start to get nervous when I see any of the following conditions:

1). Wall Cloud. Lowering, rotating cloud base. This "wall cloud" is where tornadoes are most likely to spin up.
2). Large hail. The larger the hail, the stronger the T-storm updraft, the greater the potential for tornadoes. I start to worry when hailstones are golfball-size or larger. Baseball-size hail? Head to the basement. Don't wait for warnings or the sirens to sound.
3). Debris visible: sparks on high-tension wires. These are additional tell-tale signs that a tornado circulation may be reaching the ground.
4). Black/green sky. A green or yellowish tint to the sky often means significant hail in the thunderhead overhead. It's not a foolproof tip-off, but trust your gut, and your instincts. If winds are increasing sharply, and large hail is falling, it's time to head for the basement, or a small, windowless room near the interior of your home or office.

* The smaller the room, the better. The more walls between you and the tornado, the better.

Severe Storm Potential. The local Twin Cities office of the National Weather Service has outlined the greatest threat area, covering most of central and southern Minnesota.

Sliding Into A Stormier, Wetter Pattern. The good news: we're about to put a big dent in our ongoing drought. The bad news: the surge of warmth and moisture will spark a few severe storms, especially later today and Wedneday. Highs reach well into the 70s, possibly topping 80 today and tomorrow, with a gradual cooling trend by the weekend. The ECMWF (European) model prints out nearly 2" of rain next Monday. We'll see, but from a moisture standpoint the models are encouraging.

Hints of June. The U.S. model suite shows highs possibly topping 80 today and tomorrow - depending on how much sun we experience. If clouds/stratus/fog lingers into midday we'll have to be content with mid 70s. If the sun is out through midday then 80 F. is a pretty good bet. The warmer the mercury, the more unstable the airmass overhead, the greater the potential for a severe outbreak by evening. All the models show readings cooling into the 60s and low 70s by the weekend; right now Saturday looks a few degrees milder than Sunday.

Dripping Dew Points. All the models show the dew point rising above 60 today, and staying in the 60-65 F. range into Friday. There will be plenty of moisture in the air, enough fuel for strong/severe T-storms.

Great News For Fields, Lawns and Gardens. It's not enough rain to replenish low lake-water levels, but it's a big step in the right direction. Models are suggesting over 1" of rain by Thursday night, maybe 2"+ amounts for parts of Minnesota and western Wisconsin.

Soaking Rains? A robust warm frontal boundary draped over central Minnesota and Wisconsin will act as a magnet for "waves" of showers and T-storms - best chance late afternoon into the overnight hours; storms will tend to weaken rapidly during the morning hours. The latest NAM predicts over 1" of rain for the Twin Cities metro by Thursday night, with some 1-2" amounts over southern Minnesota and western Wisconsin.

"Spread joy. Chase your wildest dreams." - Patch Adams

"Last year the Arctic Monitoring and Assessment Program (AMAP) concluded that Arctic temperatures in the past six years were the warmest in measured history. Each year since 2001, summer ice coverage in the Arctic Ocean has been at, or near, a new record low, a pace that predicts ice-free summers in the Arctic Ocean in the next 30 or 40 years." - from an Op-Ed in West Virginia's wvgazette.com.

A Warmer March Than April? Amazing, but true. Details from the NWS office in Binghampton, New York: "For the first time EVER in our climatological records, April has turned out to be colder than March. These stats do not yet include today, April 30th, but will change very little (by 0.1 of a degree or so at most) when the final numbers are calculated."

Record March-April Snowfall Deficit For Denver. Here's an interesting post from the Denver/Boulder office of The National Weather Service, via Facebook: "The total snowfall for March and April combined was 1.0”. This is the lowest combined March-April Snowfall on record dating back to 1882. The previous low was 1.1” in 1887. The average is normally 20.5” based on the period of record. Furthermore the last two years the combined March-April Snowfall has been below 5.0”. This has never happened before dating back to 1882."

Spectacular Snaps Of Tornado That Tore Through Toulouse (France). Check out some amazing photos from The U.K. Sun: "A tornado touched down in southern France yesterday - long enough to be captured in a series of spectacular pictures and videos. Storm chasers snapped the dust-laden funnel, known as an F-1 tornado, as it stormed through Toulouse at speeds of up to 112mph."

* no, that's not a typo: tornado chasers in southern France. That's a new one.

Weather Channel's 30th Anniversary Plans. Details from Media Bistro's TVNewser: "On Wednesday, The Weather Channel will celebrate 30 years on the air. The channel is planning a celebration on-air online and in the real world. For starters, the Empire State Building will be decked out in “Weather Channel Blue” lights for the anniversary. On-air, there will be a retrospective looking back on 30 years of coverage, as well as interviews with key players, employees and on-air personalities. Celebrities and prominent figures will offer congratulations, and a blooper reel will be played."

Artist Floats "Real Clouds" Indoors. I need one of these machines - that way my forecast will never be wrong. AccuWeather.com has more details: "Dutch artist Berndnaut Smilde floated clouds indoors for two art exhibits in the Netherlands. Smilde used a fog machine to build the clouds in the room."

Freedom Tower: 11 Beautiful Instagram Images of NYC's Tallest New Building. Mashable.com has the story; here's an excerpt: "A steel beam was secured to One World Trade Center Monday, making it officially the tallest building in New York City. The tower now stands at 1,271 feet, and users on Instagram have been sharing their view of the building from all over New York, using the hashtags #WTC1 and #FreedomTower. Once finished, the building will be 1,776 feet have 104 floors, including 71 office floors with 3 million square feet of space."

Mommy Confession: I Let My Toddler Wear Make-Up. Good grief. I saw a tweet from KMSP and had to get more details on this "breaking story"; more details from mommyish.com. Yep, "ish" kind of sums it up: "This weekend, my daughter had her spring pre-school performance. As we were getting ready, practicing her songs and pulling out her “good shoes,” she walked into the bathroom and reminded me that I needed to plug in the curling iron. “Mom,” she bellowed from across the house, “you need to turn on the hot curly thingy.” Brenna and I have a pretty solid “dress-up” routine. Every holiday, performance, or any other event that she deems necessarily fancy, we pick out a pretty dress, curl her hair and then we apply a little make-up. Alright, we apply a full face of make-up. On both of us."

Discovery Channel Crashes 727 To See To, Um, See What Happens. Speaking of crashing and burning, CNET.com has details on a perfectly good waste of a Boing 727: "It is always a little frightening to see a plane plummet towards Earth, especially if you're often forced to travel in one. What might it have looked like for those who, last Friday, watched a 727 crashing in the Mexican desert -- with the full knowledge and co-operation of the pilot? I am grateful to the Daily Mail for making my Monday so much more exciting with this information. According to a Discovery Channel press release, this was done in the service of "an unprecedented international television documentary for Discovery Channel, Channel 4 in the UK, plus Pro Sieben in Germany."

Why We Love To Use iPad Indoors: WIFI. The details from gigaom.com; here's a snippet: "By analyzing data from a live 3G network in a major city, the mobile network analytics and optimization specialist has found that only 5% of iPads are used outdoors and whilst iPads account for just 1% of data sessions, they use four times more data than an average 3G device. Key findings from the study were:

• iPads account for less than 1% of all data sessions but make up 5% of total traffic."

Berries Can Keep Your Brain Sharp. So this is why my dear wife is force-feeding me berries: she's trying to keep my brain sharp! But you just can't sharpen a rusty knife. That said, there is some good information in this story from gizmag.com; here's an excerpt: "Everyone knows that strawberries and blueberries are good for you. Now a new study by researchers at Brigham and Women’s Hospital (BWH) has found that eating as little as two servings of flavonoid-rich strawberries and/or blueberries a week can delay memory decline in older women by over two years. The research team used data from the Nurses’ Health Study, which involved more than 120,000 registered nurses between the ages of 30 and 55. The nurses completed health and lifestyle questionnaires beginning in 1976, and have been surveyed every four years since regarding their eating habits. Starting in 1995, memory was tested in participants older than 70 every two years. Women included in the present study had a mean age of 74."

Another Step In The Right Direction. The forecast called for upper 60s to near 70. Eden Prairie experienced a high of 67 by evening, but MSP International only reached 63 F. Morning clouds lingering longer, delayed sun kept us 5 degrees cooler than they would have been otherwise. Statewide Monday highs ranged from 45 at Grand Marais to 60 Rochester, 68 St. Cloud and 70 at Redwood Falls.

"Safe Rooms"

Ever since the movie "Twister" thousands of would-be amateur photographers have taken to America's highways, checking Doppler, trying to be at the right place at the right time, capturing tornado footage that will a). get them paid, and b). show up on TV. 

I have mixed feelings. The swarm of tornado chasers is triggering potentially dangerous traffic jams, in some cases making it harder for first responders to reach tornado damage. But studies repeatedly show that many Americans don't head to the basement until they SEE that the tornado threat is real. Warnings and sirens simply aren't enough to get some off the dime.

No basement? Consider spending a few thousand dollars to reinforce an interior closet. These "safe rooms" are booming down south and might be a good idea for northern homes. In recent years, for a variety of reasons, many still unclear, some of the largest, most violent tornadoes have been touching down outside of traditional "Tornado Alley". In 2010 Minnesota experienced the most tornadoes in the USA (145). There's no evidence that this spring/summer season will rival 2010 - but we need to be ready.

You know the drill: small, windowless rooms on the ground floor afford the most protection (closet or bathroom usually works best). If you're in an office the safest place is an interior (concrete-reinforced) stairwell or bathroom. If a warning is issued and you're home with the kids consider football or hockey helmets. Don't laugh. Most tornado injuries are blunt head trauma. A helmet could - in theory and reality - save your life.

T-storms later today may be severe - I expect a few tornadoes fairly close to home. The good news: no more jackets. If the sun comes out we may hit 80 through Friday. A damp start Saturday gives way to slow clearing; the best chance of Sunday storms over southern Minnesota.

"The sun, the moon and the stars would have disappeared long ago...had they happened to be within the reach of predatory human hands." - Havelock Ellis, "The Dance of Life", 1923

Climate Stories...

Joe Wyatt: Global Warming Is Real. Here's an excerpt of a must-read Op-Ed from heart of "clean" coal country: West Virginia's Sunday Gazette-Mail: "....Limbaugh has yet to explain how the researchers' well-oiled scheme was put into place. If Rush is correct, thousands of scientists have put on hold their self-involved hopes for the Nobel Prize so that they may surreptitiously conspire to deceive us about air temperature. And they have done this unobserved, even though they work for numerous governments, hundreds of agencies, dozens of universities and a myriad of research groups in far-flung nations. One wonders whether Rush suffers hallucinations in which secret handshakes are exchanged at clandestine meetings in little used rooms of dusty basements far beneath the classrooms of ivy-covered chemistry buildings. In contrast to such paranoia, the National Climatic Data Center said that 2010 was the second hottest year in history, after 2005. The National Oceanic and Atmospheric Administration (NOAA) reported that more than 15,000 warm temperature records fell nationwide during March this year."

Listen To The Skeptics! Except When They Talk Nonsense. From Climate Central: "I got an email the other day from an occasional visitor to the Climate Central website, asking whether we’d be covering a series of recent challenges to conventional climate science. He was being facetious: he knew we probably wouldn’t, and he was right — clear evidence, he proclaimed triumphantly, that our claim of following the science wherever it leads is just a lot of empty talk. My first reaction was: “how dare you suggest such a thing!” But that’s a throwaway line, not a response, and I thought I should provide a fuller answer. The bottom line is that we ignore people who claim to have found holes in the mainstream ideas of climate change if their claims don’t make lot of sense. Who gets to decide? Well, we do. But it’s not arbitrary: there’s a thought process behind it, and it’s a pretty valid one, though it’s not infallible."

U.S. Wind Energy At The Crossroads. Here's a video clip from climatecrocks.com: "Wind energy is not a future resource, it is here now. There is no question that it will be a primary part of our energy mix in the future. The only question is, will we build those millions of turbines here in the US, or will we concede the growth industry of the 21st century to our competitors."

Wind Farms Can Increase Night Time Temperatures, Research Reveals. An interesting potential symptom of turning turbines: it keeps the air stirred up at ground-level, preventing the coldest air from settling to ground level, as reported by The Guardian: "Large windfarms can increase local night time temperatures by fanning warmer air onto the ground, new research has revealed. The study used satellite data to show that the building of huge windfarms in west Texas over the last decade has warmed the nights by up to 0.72C. "Wind power is going to be a part of the solution to the climate change, air pollution and energy security problem," said Liming Zhou, at the University of Albany in New York. "But understanding the impacts of windfarms is critical for developing management strategies to ensure the long-term sustainability of wind power."

Wind Farms May Have Warming Effect: Research. Details from Reuters and the Baltimore Sun: "LONDON (Reuters) - Large wind farms might have a warming effect on the local climate, research in the United States showed on Sunday, casting a shadow over the long-term sustainability of wind power. Carbon dioxide and other greenhouse gases from burning fossil fuels contribute to global warming, which could lead to the melting of glaciers, sea level rise, ocean acidification, crop failure and other devastating effects, scientists say."

Flooding Spreads Invasive Species In Vermont, Iowa, Louisiana. Here's a snippet from a story at Huffington Post: "BETHEL, Vt. (AP) — Last year's hurricanes and flooding not only engulfed homes and carried away roads and bridges in hard-hit areas of the country, it dispersed aggressive invasive species as well. In Vermont, the floodwaters from Tropical Storm Irene and work afterward to dredge rivers and remove debris spread fragments of Japanese knotweed, a plant that threatens to take over flood plains wiped clean by the August storm. The overflowing Missouri and Mississippi rivers last year launched Asian carp into lakes and oxbows where the fish had not been seen before, from Iowa to the Iowa Great Lakes. Flooding also increased the population along the Missouri River of purple loosestrife, a plant that suppresses native plants and alters wetlands."

Which Hotel Chain Has The Smallest Carbon Footprint? The fact that a major media outlet is even asking the question is an encouraging sign. Here's an excerpt of an interesting story from The L.A. Times: "If you want to shrink your carbon footprint when you check into a hotel, you may be better off staying at a mid-range or budget chain hotel. That's the conclusion from a report released last week by Vermont-based Brighter Planet, the eco-minded tech firm that creates digital apps and other technology to measure environmental impacts. The report said the nation’s hotels use 4% of all commercial building energy per year and generate 34.7 million metric tons of greenhouse gas emissions. The most energy- and carbon-efficient hotel chain in the U.S., according to Brighter Planet, is Vagabond Inn, followed by Red Lion Hotels, both mid-range national hotel chains. Red Carpet Inns, a budget hotel chain, came in third."

App Depicts Impact Of Climate Change On Planet. Reuters has details: "Called Fragile Earth, the app for iPhone and iPad shows how our planet is impacted by global warming by featuring more than 70 sites such the receding Muir Glacier in Alaska, the impact of Hurricane Katrina in New Orleans and the draining of the Mesopotamia Marshes in Iraq. "We don't necessarily put an opinion on it," said Jethro Lennox, head of publishing at Collins Geo, a division of Harper Collins UK which created the app. "We're just trying to visually portray some of the geographical features and changes around the world."

Report: China Doing Most Global Warming Abatement, Global Greenhouse Gas Emissions To Peak In 2016, But Still Not Enough. Details from Clean Technica: "The DB Climate Change Advisors has released its latest Global Climate Change Policy Tracker report [PDF], its fourth. The report has quite a bit of interesting info in it. Most important, from a global perspective, is that “the best case global outlook” based on potential current targets still leaves us is with “a 5.8Gt ‘gap’ compared to a 450ppm stabilization pathway.” And even 450ppm is way to high according to top climate scientists."
