Nothing Severe - Welcome Spring Showers This Week
Were you outside yesterday? Looking at the sky was the rough equivalent of staring up through a dirty aquarium, which I don't recommend. An orange haze? It looked like L.A. - with lakes. Vast smoke plumes from the Fort McMurray, Alberta mega-blaze have been sweeping south into the USA; a vivid reminder than everything is interconnected.
Why so bad, so early in the season? Less winter snow, an early spring and record warmth were all factors. It's not limited to Canada. "Climate change has led to fire seasons that are now on average 78 days longer than in 1970," the U.S. Forest Service said in an August 2015 report. "The U.S. burns twice as many acres as three decades ago and Forest Service scientists believe the acreage burned may double again by mid-century" said a recent CNN story.
No complaints about rain in the forecast this week. Anywhere from .5 to 1 inch of rain may fall from this afternoon into Thursday, followed by cooler air. By late week highs hold in the 50s with a light frost over northern Minnesota next weekend.
No worries: balmy 70s & 80s return late next week.
Second Warmest Start to the Year on Record for U.S. Here's a clip from Climate Central: "While the weather is chilly and rainy along much of the East Coast, the Lower 48 as a whole is having its second hottest year to date, thanks in large part to major western warmth, the National Oceanic and Atmospheric Administration announced Friday. That warmth extended all the way up to Alaska, which is seeing its warmest year on record and temperatures far above normal..."

Tracking Smoke Plumes. That orange-blue haze was the result of massive fires in Alberta; steering winds aloft pushing the core of the smoke plume southeast into Minnesota, creating a sky only a Californian could love. Sunday afternoon visible satellite loop: WeatherTap.
30s by Saturday Morning? All the models are in agreement; showing a gradual cooling trend into next weekend, when wake-up temperatures may dip into the 30s. A metro frost is unlikely, but St. Cloud and Brainerd? All bets are off for central and northern Minnesota. Model data: Aeris Enterprise.
One More Relapse. On a positive note it probably won't snow, and the new annuals planted in the garden should be OK, at least in the metro, but ECMWF data shows lows dipping into the 30s Saturday through Monday of next week; one more swipe of formidable Canadian air. Graphic: WeatherBell.
Midweek Soaker? Our internal model ensembles sent out an alert for 1.1" of rain at MSP by Wednesday evening at 7 pm. Let it rain - especially on weekdays. Source: Aeris Enterprise.
A Colorful Precipitation Map = Significant Rains This Week. 4 KM NAM guidance prints out some .5 to 1" rainfall amounts by Wednesday evening, which seems reasonable, given the slow movement of the next approaching system. Accumulated precipitation outlook: NOAA and AerisWeather.
Enough Rain To Settle the Dust - and Smoke. Latest (00z) NAM guidance prints out 1.53" of rain in the Twin Cities by late Wednesday night. Your emerging flowers are thrilled to hear the news.
Warming Trend Returns by Last Week of May. Have no fear - it will warm up again, as early as next week. Another bubble of warm high pressure should pull temperatures back into the 70s, even a few 80s, within 2 weeks or so.
The Fort McMurray Fire Created Lightning That Set Off New Blazes. These mega-fires literally create their own weather which can help to perpetuate the blazes until winds ease, humidity levels rise and rain arrives. Here's an excerpt from VICE News: "...It takes an extreme fire to produce a thunderhead — and what happened at Fort McMurray may be a first, said Mike Flannigan, a wildfire researcher at the University of Alberta. "We've had these types of things with lighting before, but this may be the first documented case in which lightning started new fires," Flannigan said. The blaze is so intense, witnesses have reported that broadleaf trees like aspens — known for being more resistant to fire than evergreens — "caught fire in one big whoosh" like a barbecue grill being lit. And if early damage estimates of $8-9 billion bear out, "It would be the most costly natural disaster in Canadian history," Flannigan said..."
Explosive Growth. Canada's CBC News has an animation that shows the mind-boggling spread of the Fort McMurray fire in the span of only 6 days.
Unusual Spring Warmth Helped to Set the Stage for Fort McMurray Conflagration. Here's an excerpt from an explainer at NASA's Earth Observatory: "...In early May 2016, a destructive wildfire burned through Canada’s Fort McMurray in the Northern Alberta region. Windy, dry, and unseasonably hot conditions all set the stage for the fire. Winds gusted over 20 miles (32 kilometers) per hour, fanning the flames in an area where rainfall totals have been well below normal in 2016. Ground-based measurements showed that the temperature soared to 32 degrees Celsius (90 degrees Fahrenheit) on May 3 as the fire spread. Satellite observations also detected the unusual heat. The map above shows land surface temperature from April 26 to May 3, 2016, compared to the 2000–2010 average for the same one-week period. Red areas were hotter than the long-term average; blue areas were below average. White pixels had normal temperatures, and gray pixels did not have enough data, most likely due to cloud cover..."

First Autonomous Robot to Operate on Soft Tissue Outdoes Human Surgeons. Is surgery the next industry to be disrupted? Here's the intro to a story at Ars Technica: "Step aside, Ben Carson. The once lauded ability to perform delicate operations with gifted hands may soon be replaced with the consistent precision of an autonomous robot. And—bonus—robots don’t get sleepy. In a world’s first, researchers report using an autonomous robot to perform surgical operations on soft tissue and in living pigs, where the adroit droid stitched up broken bowels. The researchers published the robotic reveal in the journal Science Translational Medicine, and they noted the new machinery surpassed the consistency and precision of expert surgeons, laparoscopy, and robot-assisted (non-autonomous robotic) surgery..."

Shelby Challenges Seniors to "Get Out of their Seats". Don's a good friend - so he won't care if I show up and heckle him (from my seat). Here's an excerpt at Eden Prairie News: "...The first part of our lives is basically lived in a cocoon of protection and tutelage and then we go out into the world and struggle,” he said. “It is a slog for a lot of people to get through to a point when they can at last retire. Then society tells us that we’re of no use. We’ve served our useful purpose. Now why don’t you just slip into the background and be quiet and let the new generation handle the world? “And it’s a shame that all of that accumulated wisdom, knowledge and experience is cast aside by commentators and media that tells people that they’re now aged, the elderly, the senior citizens. “The message is wrong. We have a lot more to give. We have the most to give,” Shelby said..."

What Do Consumers Want? Look at their Selfies. Now you can market your selfies - to sell toothpaste. Here's an excerpt from The New York Times: "...If Ms. Shragal takes enough selfies with her smartphone and uploads them to a special app, she has “an extra $20 to go get my nails done,” she said. Her seemingly mundane images, when combined with thousands of others, contain insights that companies like Crest are eager to mine. They are using a Chicago-based company called Pay Your Selfie to gather those insights and present them in reports on consumer behavior that are meant to go where focus groups and surveys cannot..."
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 troublilng 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..."

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..."

We Need to Talk About Climate Change. Meteorologist Eric Holthaus connects the dots and explains why it's necessary to talk about the conditions that prime the pump for extraordinary events; here's an excerpt from his essay at Slate: "...Many people have expressed outrage at the fact that climate change is being mentioned as a contributing cause to this fire. It is “insensitive” to the victims to bring up something so political at a time like this, they argue. I want to be clear: Talking about climate change during an ongoing disaster like Fort McMurray is absolutely necessary. There is a sensitive way to do it, one that acknowledges what the victims are going through and does not blame them for these difficulties. But adding scientific context helps inform our response and helps us figure out how something so horrific could have happened. We’ve reached an era where all weather events bear at least a slight human fingerprint, which, as Elizabeth Kolbert points out in the New Yorker, means “we’ve all contributed to the latest inferno...”
The Fire in Canada Looks a Lot Like Climate Change - And That Should Scare You. Or at least get your attention - again. Here's an excerpt from an Op-Ed at CNN: "...This is an example of what we expect -- and consistent with what we expect for climate change," said Mike Flannigan, a professor of wildland fire at the University of Alberta who's been studying climate change and wildfire for decades. "This fire is unprecedented," he said, referring to its local impact. It's impossible for scientists to say global warming caused this specific fire, of course, but polluting the atmosphere is creating conditions that make such disasters more likely, bigger and costlier. "In Canada, our area burned (by wildfire) has more than doubled since thLe early 70s," Flannigan said. "And we've published work that states that this is because of human-caused climate change..."

How Climate Change May Be Fueling Canada's Fire Season. The Washington Post has additional perspective; here's an excerpt: "...Robinson has suggested that earlier melting, like what we’ve seen in the northern hemisphere this spring, can give forests and grasslands a chance to dry out earlier and provide the potential for a longer fire season. It’s a point other experts have raised as well. “The earlier the snow melts, the longer the fire season — so the more days during which fires can ignite and burn,” said David Martell, a forestry professor and fire expert at the University of Toronto, by email, although he noted that he’s unaware of any studies that have explicitly investigated this connection..."
