.19″ rain fell at Twin Cities International Airport as of 7 pm yesterday.
May 10, 1934: ‘The Classic Dust Bowl’ hits Minnesota. Extensive damage occurs over the region, with near daytime blackout conditions in the Twin Cities and west central Minnesota. Dust drifts cause hazardous travel, especially at Fairmont where drifts up to 6 inches are reported. Damage occurs to personal property due to fine dust sifting inside homes and businesses.
Welcome Puddles – Over 1 Inch of Rain by Wednesday
“The way I see it, if you want the rainbow, you gotta put up with the rain” said Dolly Parton. Smart woman.
It’s hard keeping farmers, boaters & commuters happy, simultaneously. Maybe if we could time the rain after 8 pm on weeknights – reserve blue sky for weekends? Dream on.
I’m happy to see the rain, for a variety of good reasons. The Fort McMurray mega-blaze may be Canada’s worst natural disaster on record. Much of northern Minnesota is too dry. The first 4 months of 2016 were the second warmest in 135 years of records, according to NOAA. And new data suggests we’re sliding into a moderate La Nina cool phase in the Pacific, which correlates with a greater drought risk for Minnesota. Let it rain.
NAM guidance from NOAA prints out over 1 inch of rain between now and Wednesday. Embedded T-storms are possible, but conditions aren’t favorable for anything severe, not yet. Cool exhaust behind the storm drops temperatures into the 30s by Saturday morning – a lingering breeze may prevent a widespread frost. Don’t panic: 70s return within 2 weeks. Spring is fickle.
I know, shocking.
Another Inch of Rain? It seems more than plausible, based on latest model guidance. In fact our model ensemble at Aeris Weather suggests an additional inch of rain by 11 pm Wednesday night.
Million Dollar Rain. It may complicate your commute the next couple of days, but farmers and gardeners are welcoming these waves of rain – coming at a very good time (after the bulk of spring planting with crops in the ground). Models show nearly 1″ of rain by Thursday morning. Source: Aeris Enterprise.
Two Waves of Heavy Rain. The first comes this morning; a second surge of southern moisture sparking another round of showers and possible T-storms late Wednesday and Wednesday night.
Late Week Cool-Down. The same storm responsible for serious puddles into Thursday morning will pull cooler air back into Minnesota by Friday; Saturday morning temperatures may dip into the mid-30s in outlying suburbs from Maplewood to Elk River, Medina and Prior Lake.
ECMWF Numbers. European guidance shows highs holding in the 50s Friday into Sunday with mid to upper 30s for weekend wake-up temperatures in the metro. I still believe the immediate MSP metro area will avoid a frost, but 30-50 miles away from the downtowns it could be a different story. Graphic: WeatherBell.
Mellowing May Warmth. High temperatures return to the 60s next week; with 70s the weekend after next. The sun angle is too high in the sky for cool weather to linger for long. 500 mb GFS winds valid Monday evening, May 23.
April Weather Summary. Here’s an excerpt from NOAA NCDC: “…Above-average precipitation was observed across the Great Plains and Rocky Mountains. Seven states throughout the Great Plains, stretching from Montana to Texas, had an April precipitation total that was much above average.
- Several rounds of heavy precipitation impacted parts of Texas during April causing widespread flooding. Houston was hit particularly hard on April 18 when 9.92 inches of rain was observed at the George Bush Intercontinental Airport; even higher amounts were observed to the northwest of the city. This was the second highest one-day precipitation total for the city, bested only by the 10.34 inches that was observed during Tropical Storm Alison in 1989. As a whole, Texas had its ninth wettest April with nearly 180 percent of average rainfall…”
Scorched Remains: Haunting Images From a City Destroyed by Wildfire. Mashable has the story and photos; here’s an excerpt: “…The wildfire, fueled by high temperatures, strong winds and dry conditions, has burned more than 385,476 acres (156,000 hectares) and could gobble up 741,300 acres (200,000 to 300,000 hectares) by the end of Saturday, Chad Morrison of Alberta Wildfire said. It has so far destroyed 1,600 buildings, but no deaths or injuries were reported Saturday. “In no way is this fire under control,” Alberta Premier Rachel Notley told the Associated Press. Cooler temperatures and possible rain are expected Sunday, however it would take significant rainfall to tamp down the powerful fire. Authorities expect to be battling the blaze for months...” (Photo credit: CBC News Edmonton).
A Ride Into the Ashes of Fort McMurray. VICE News has the story and some harrowing images; here’s an excerpt: “…Dozens of wildfires in Alberta, collectively dubbed the “beast,” have grown to cover nearly more than 150,000 hectares this week — about three times the geographic footprint of Canada’s largest city, Toronto — and are now pushing into neighboring Saskatchewan. In addition to boots on the ground, Alberta has 15 helicopters, 14 air tankers and 88 other pieces of equipment trying to control the flames. Saturday evening, officials reported that more than 2,000 vehicles were able to travel safely south through Fort McMurray as part of a massive military-led mobilization that escorted people who had been sent north in the chaos of the initial evacuation...” (Image credit: Dan Olson/VICE News).
Chaos Limits Predictability of Hurricane Intensities. Models are doing a pretty good job with hurricane track, but intensity remains a huge challenge – and there may be limits to how accurately we can predict hurricane intensity. Here’s an excerpt from a new paper highlighted at Physics Today: “…Yet the errors in forecasts of hurricane intensity don’t go away as one might expect; rather, speed errors level off at about 8 m/s (18 mph) after four to five days in real-time intensity forecasts. Through full-physics simulations, the pair discovered that those errors arise from a so-called chaotic attractor at the maximum potential intensity limit. That finding implies that improvements in intensity forecasts are more likely to come from better modeling of the large-scale environment than from better knowledge of the storm’s initial state. Even so, the researchers note, the maximum range of predictability is only about three days, and likely shorter for mature hurricanes...” (File image of 2007 Hurricane Felix: NASA).
Western U.S. Snowpack Melting at Record Speed. Capital Public Radio looks at the implications of rapid warming and melting: “…The U.S. Department of Agriculture’s Natural Resources Conservation Service issued its final “west-wide forecast” of the season this week. It shows that snowpack, from Washington to Wyoming, is melting so quickly, flooding is a possibility in some areas. “Most areas saw major decreases in snowpack during April and are now below normal,” according to the NRCS May 2016 Western Snowpack and Water Supply Conditions report...”
Man Captures Some of the Most Dramatic Footage Ever Taken of a Tornado. That’s quite a mouthful, but the video is compelling. Here’s a link and story excerpt from San Antonio Express-News: “...A video posted on YouTube Saturday shows some of the most dramatic up-close footage of a tornado ever captured on film. According to the Associated Press, a tornado hit just north of Wray, Colo., Saturday evening about 7 p.m. It injured five people was one of several tornadoes that hit Colorado Saturday. The AP wrote that storm chasers tracked the tornado for about 10 miles once it hit the ground…”
A 3-D, 30K Lifesize Replica of Yourself. Why not, for people who have more money than sense this sounds like the gift that will keep on giving! Here’s an excerpt of a fascinatingly troubling article at The Next Web: “Today in “Sure, why not,” Groupon is offering – what else – a deal of a lifetime that lets you 3D print a life-size replica of yourself for only $30,000. And it’s being offered as Mother’s Day special. In collaboration with Alabama-based 3D-printing company SWIGRO, the deal includes travel to the headquarters to create your body’s blueprint and framework, and free shipping within the United States. It won’t likely arrive in time for actual Mother’s Day (this Sunday, May 8) but if you’re seriously considering getting this as a gift for the lady who raised you, we’re guessing it doesn’t matter when mom’s day is…”

See Earth’s Temperature Spiral Toward 2 Degrees Celsius. Climate Central has the story and (amazing) visualization; here’s an excerpt: “The steady rise of Earth’s temperature as greenhouse gases accumulate in the atmosphere and trap more and more heat is sending the planet spiraling closer to the point where warming’s catastrophic consequences may be all but assured. That metaphoric spiral has become a literal one in a new graphic drawn up by Ed Hawkins, a climate scientist at the University of Reading in the United Kingdom. The animated graphic features a rainbow-colored record of global temperatures spinning outward from the late 19th century to the present as the Earth heats up…”

Raging Canadian Wildfire Points to Global Warming. CBS News has the story; here’s the intro: “The wildfire that has devastated the remote Canadian town of Fort McMurray has caused an estimated $7.3 billion in insurance-related losses, the most from that type of disaster since 1970. Experts say the size of the blaze, along with an increase in the number of wildfires in the U.S., are evidence of global warming. “This is one of the parts of the world that has seen warmer and warmer winters and accelerated springs and drier conditions, which are linked to increasing atmospheric greenhouse gasses and the long-term warming that we’ve seen,” said Glen MacDonald, a professor of geography at University of California at Los Angeles, in . “It’s just not surprising that you would have an event like this...” (Image: CBC News).
Inland Flooding Threat to Increase by 2050. WXShift has the analysis – here’s an excerpt of a recent story: “…The recent flooding in the Gulf Coast states highlights the increasing threats from heavy precipitation with climate change. Our States at Risk report examined the intensity and duration of the heaviest runoff events for each state. To determine the future inland flood threat, the report examined the frequency of high water runoff that could lead to flooding threats both currently and in the future. In this week’s analysis, we examine both the state and national projected trends for heavy runoff. Our Flooding Severity Index is used to quantify the runoff. This index is the average yearly sum of the daily total runoff which exceeds the 95th percentile of a 1990-2010 baseline. Using this index incorporates both intensity and duration of the runoff in each state (a full methodology can be found in the States at Risk report)...”
South Florida Republicans Lead Their Party from Climate Change Denial. The Charlotte Observer has a story focused on how southern Florida is on the front line of sea level rise associated with a warming, rising sea – here’s a clip: “Republican Rep. Carlos Curbelo and Democratic Rep. Ted Deutch, whose South Florida districts are already enduring increased flooding, salt water intrusion and other effects of rising sea levels, are leading the first truly bipartisan congressional effort to tackle climate change. Joined by Rep. Ileana Ros-Lehtinen, a Miami Republican, they’ve formed a caucus that uses an unusual “buddy system” in which each Democratic member must bring along a Republican colleague willing to renounce party orthodoxy and stop minimizing the peril – or even existence – of global warming…”

Florida Mayors Rush to Prepare for Rising Seas. Here’s an excerpt from ThinkProgress: “Cindy Lerner and Carlos Gimenez are, in many ways, typical local politicians. Both are mayors, and both are intimately familiar with the trials and tribulations that their constituents face on a daily basis, from trash pickup to traffic. Both serve communities along the southeastern Florida coast — Gimenez is mayor of Miami-Dade County, the most populous county in Florida and the seventh-most populous county in the United States, while Lerner is mayor of the village of Pinecrest, a suburban village of about 18,000 residents located within Miami-Dade County. And yet both are in a unique position for a local leader: they both believe that climate change is occurring, and that the consequences will hit Florida residents hard. That puts them at odds with the state government, led by Governor Rick Scott, which fervently denies that climate change is occurring...” (File photo credit: Shutterstock).
Philippines Investigates Shell and Exxon Over Climate Change. Here’s a clip from a summary at The Guardian: “Can Chevron, ExxonMobil and BP be held accountable for the vulnerable communities most affected by climate change? It’s a question a legal case in the Philippines could answer. Last month, lawyers for the petitioners met with the Commission on Human Rights of the Philippines (CHR), a constitutional body tasked with investigating human rights violations. Their goal was to identify expert witnesses for a hearing into the liability of 50 of the biggest fossil fuel companies for violating the human rights of Filipinos as a result of catastrophic climate change…”

Exxon Scrambles to Contain Climate Crusade. Politico reports; here’s a snippet: “…The meeting marked a striking shift in Exxon’s handling of the controversy. The notion of holding oil companies responsible for global warming, in the same way tobacco companies had to pay billions of dollars in damages over the health effects of cigarettes, had long been seen as a quixotic quest led by scruffy, oil-hating extremists. But POLITICO’s interviews with dozens of activists, industry officials and lawmakers suggest that support for a legal crusade against Exxon is growing far beyond the political fringe — and now poses the biggest existential threat the company has faced in decades...” (File photo: Reuters).
Meet the Utah Columnist Shining a Light on Fossil Fuel Front Groups. Here’s an excerpt from Media Matters: “In recent decades, fossil fuel interests have been funding front groups to advance their ideological and political goals, and key to these groups’ success is concealing their industry backing. But Utah columnist Paul Rolly has been working to shine a light on the industry backing behind the most influential front groups in his state. In an interview with Media Matters, Rolly discussed the importance of following the money. Rolly has been a columnist at The Salt Lake Tribune for the last 20 years, and he has stood out because of his work exposing fossil fuel front groups operating in Utah. He has uncovered the oil industry fingerprints behind campaigns to seize public lands from the federal government, attack renewable energy, and promote an industry-friendly agenda in higher education…”
The Coming Refugee Crisis: When Home Leaves Us. Here’s an excerpt of a poignant essay at The Guardian: “…The economic, political and psychological toll of the coming droughts, famines, wars, storms and rising seas is difficult to fathom. Yet remarkably, even in this active political season, the need to adapt to climate change has hardly been mentioned. For Louisiana, my home state, the stakes couldn’t be higher. We’ve lost the equivalent of Delaware’s entire landmass over the past century, and the familiar outline of the state is being eaten away. The wetlands that once provided bountiful resources while serving as a buffer against storms and floods are continuing to vanish at an alarming rate. Watching the Louisiana coast sink faster than any other shoreline on the planet while being buffeted by ever-rising seas and storms, one thing is clear. It’s not that we are leaving home, but that home is leaving us…”
