Sweating into September

 Smokey Sunsets
WOW! Thanks to my good friend Stephanie Chanaka Johnson for the picture below. This was taken over the weekend of one of our last (meteorological summer) sunsets of the year. Smoke from western wildfires helped to produce some brilliant smokey sunrises and sunsets over the last several days. The full moon rises and sets were pretty nice too!! Hope you enjoyed them!!



Smoke and Wildfire Analysis
Airnow.gov has a neat map that shows daily the wildfire and smoke analysis across the country. The map below shows how widespread the smoke was from Tuesday, September 1st. Note that most of the fires are in the western U.S., while much of the smoke was still across the central and eastern U.S..



Wednesday Smoke Analysis
NOAA also has a neat smoke analysis map. This is the forecast for Wednesday at 2pm, which show that much of the smoke from western wildfires will have lifted north into Canada. The threat for smokey sunrises/sunsets has ended for much of the central/southern part of the country... for now.



Low Expectations
By Paul Douglas

"It is best to read the weather forecast before praying for rain" said Mark Twain. There is now little doubt that major holidays attract puddles. Mother Nature has a wicked sense of humor. T-storms are in the forecast for the Labor Day weekend. Trying to time the rain this far out is an act of futility, but the skies will be rumbling every now and then, especially Sunday. The farther north you go, the better the odds of a few hours of hard rain.

The Dog Days of September limp on, with a heat index in the mid-90s almost every day into Saturday. If you're heading off to the State Fair stay hydrated and take plenty of breaks.

A little perspective is in order: during a typical summer MSP picks up 14 days at or above 90F. So far in 2015: only 4 days of 90-degree heat. In 2013 we enjoyed 7 days in the 90s during the State Fair! That was a truly whine-worthy spasm of late-summer heat. This warm spell is tame, by comparison.

An isolated thundershower may bubble up later today as dew points surge into the low 70s. Sweaty weather extends into Labor Day before a puff of slightly cooler, drier air arrives.

With a Super El Nino in the Pacific I'm predicting warmth well into October.

This Day in Weather History
September 2nd


1996: Approximately 8 inches of rain fell over 2 1/2 hour period in the Mankato area resulting in flash flooding. Numerous road were closed, basements flooded and $100,000 of damage from a lightning strike in Lehiller.

1992: Severe weather affected several counties in the western parts of the County Warning Area. Several tornadoes were reported along with 3/4 inch hail and damaging winds as the system passed through Pope, Swift, Stearns, Kandiyohi, Meeker, Brown and Renville Counties.

1975: Severe weather rolled through Stevens, Swift, Kandiyohi, and Meeker counties. 1.50 inch Hail was reported in Stevens and Swift. An F1 tornado also occurred in Swift at the time that the hail was reported. An hour later another F1 Tornado was reported in Kandiyohi County while 69 knot winds occurred in Meeker County. Damages were estimated at $50,000 for the two tornadoes that touched down.

1937: Severe thunderstorms over northern Minnesota, with 4.61 inches of rain dumped on Pokegama. Flooding was reported in Duluth.

Minneapolis Temperature Trend
Welcome to the dog days of September! Well above average temperatures look to continue through the upcoming weekend; a shot at 90F is not out of the question. Scattered showers and storms move in over the weekend/early next with a memorable cold front sneaking in by midweek as temperatures dip into the 70s. Enjoy the warmth while you can, we all know what's around the corner...


____________________________


Wednesday Weather Outlook
Wednesday looks like another warm and muggy day with readings more July-like. Highs will will warm into the mid/upper 80s across much of the region with a few low 90s possible across far western MN and through the Dakotas. Note that dewpoints will climb into the mid/upper 60s as well, which is considered quite sticky at any time of the year!



Wednesday Weather Outlook
A weak boundary will be in place helping to promote a little spotty shower/thunderstorm potential. The images below suggests weather and % sky cover around 2pm. Note that the best chance of t-shower activity looks to be across Wisconsin and far southeastern MN.



Wednesday Weather Outlook
Flashbacks of summer will unlimited today as a somewhat breezy south wind continues. Wind gusts could at times approach 20mph, especially across western Minnesota.



Rainfall Potential
Spotty showers and storms will be possible across the region over the next couple/few days, but according to the rainfall forecast below, we're not expecting much. In the meantime, we'll be left to tend to our lawns and gardens manually as this warm and 'mostly' dry weather continues through midday Friday.



National Weather Outlook
The loop below actually looks pretty quiet doesn't it? To be honest, there isn't much in terms of widespread heavy rain or any big storms brewing through Thursday. Pockets of heavy rainfall will be possible in the Southwest, Southwest and in the Northwest, but other than that... it's a pretty quiet and warm start to September.



5 Day Precipitation Outlook
According to NOAA's WPC, the 5 day precipitation forecast shows some of the heaviest rainfall potential over Florida and across parts of the northern tier of the nation. Florida will be dealing with some lingering tropical moisture, while impulses of energy (from a large low pressure system in the Gulf of Alaska) continue to skirt along the international border.



Gulf of Alaska Low
Here's a neat image that shows why temperatures across much of the nation are so warm (with the exception of the Pacific Northwest). A fairly large low pressure system in the Gulf of Alaska is helping to amplify a ridge of high pressure over the central part of the country with temperatures running well above average for most. This particular storm system will slowly move across Canada (in pieces) and help to cool things off a little across parts the nation over by next week.



Highs From Average Wednesday
Daytime highs on Wednesday will be running anywhere from nearly 5° to 20° above average across the eastern two-thirds of the country. Meanwhile, note that readings west of the Rockies will be running a little cooler than average thanks to the area of low pressure/trough in the Gulf of Alaska mentioned above.



6 to 10 Day Temperature Outlook
According to NOAA's CPC, the big blob of warmer than average temperatures will continue in the eastern third of the nation into early next week, but the that pocket of cooler than average weather, which is currently along the West Coast, will begin to slide east by mid month. By the 2nd to 3rd week of September, it may feel a little more like fall for the central part of the country.

Peak of Atlantic Hurricane Season Nears...
According to NOAA, the peak of the Atlantic Hurricane Season is September 10th. Over the last 100 years, there have been more tropical systems on September 10th than on any other day during the season.



Tracking the Tropics
As we approach the peak of the Atlantic Hurricane Season, there is only 1 named system in the basin. As of Tuesday, Fred was still a Tropical Storm and was drifting WNW into away from the western tip of Africa.



Fred
This was Fred on Tuesday afternoon as it continued weaken just off the Cape Verde islands. By the way, did you know the Cape Verde Islands changed their name to the Cabo Islands in 2013? I will link a story below...



Tracking a Weakening Fred
Fred became our second Hurricane of the 2015 Atlantic Hurricane season for a fairly short amount of time. The track was northwest through the Cape Verde (Cabo Verde) Islands into less favorable weather conditions, so it weakened rather quickly.



Active Pacific
This is an impressive sight, isn't it? The circulation of 3 different hurricanes ongoing in the Pacific Ocean. Interestingly, these were all category 4 storms at one point! Thankfully, the tracks have steered clear of the Hawaiian Islands!



Kilo
As of Tuesday afternoon, Kilo was equivalent to a category 2 hurricane with sustained winds to near 104mph. At this point, Kilo poses not threat to any major landmass.



Ignacio
Thankfully, Ignacio drifted a little farther north than previous forecasts... It was definitely a close call. However, Ignacio will continue pushing north into the open waters of the Pacific Ocean and stay a fish storm.



Tracking Ignacio
Note the pink colored dots when Ignacio was a Major Hurricane just east of Hawaii. I was getting nervous there for a moment that this thing was going to track right toward the Big Island. Thankfully it didn't!



Jimena
Jimena was still a strong hurricane as of Tuesday afternoon with winds near 120mph. Unfortunately, this storm is still tracking toward Hawaii, but it appears it will continue turning north away from the islands through the rest of the week.



Tracking Jimena
It seems as if the Pacific Ocean is a tropical shooting gallery right now. I am praying that none of these tropical systems end up finding there way over the Islands! Jimena looks to continue tracking north away from Hawaii through the rest of the week.

"Why NASA’s so worried that Greenland’s melting could speed up"
Here's an excerpt from an article by the WashingtonPost.com, which is a little concerning. An extensive research shows how much ice we've lost in Greenland and Antarctica since 2002. Note that the rate of ice loss is much more significant than that in Antarctica.

"NASA briefed the press on its “intensive research effort” into the rate and causes of sea level rise, releasing a suite of new graphics and visualizations showing how precisely the agency is measuring the upward creep of the oceans, currently at a rate of 3.21 millimeters per year. It would be easy to lose yourself in all of the new material, but if there’s one slide above all that really matters, it’s this one:"

A Suddenly Sweaty Minnesota State Fair - Odds of Theoretical "Hypercane" Are Very Small

86 F high temperature in the Twin Cities Monday.
78 F average high on August 31.
85 F high on August 31, 2014.

August 31, 1949: Earliest snowfall know for Minnesota. A trace of snow fell at the new Duluth Airport
August 31, 1947: Tornado hits Le Center, killing one person

September 1: "Emma M. Nutt Day". Emma was the first female telephone operator. No kidding.


September Sauna

Many years ago, on a Northwest flight, I had the good fortune of sitting next to an investment banker. "What's the best investment for the long haul?" I asked. He thought about it and surprised me with his answer. "Get a graduate degree. Go back to school. The additional salary you make will outpace any returns from stocks or bonds."

The idea that you graduate with a degree and you have all the training you'll ever need has gone the way of fax machines, quadraphonic sound, 3-D TV and New Coke. There are great options at local schools and a wealth of online courses.

Every business is being disrupted - we're all going to need to get smarter, with more skills under our belt.

Until the robots take over.

Welcome to the Dog Days of September; a streak of days with highs well into the 80s, coupled with a dew point near 70. A free sauna, in the privacy of your back yard! Models keep us uncomfortably warm and steamy into the holiday weekend with a growing chance of T-storms Friday into Sunday. No all-day washouts, but it may look more like June with a couple hours of hard rain and thunder each day.

We cool off a little by mid-month but no controversial cold fronts are brewing.

Temperature Tells Only Half the Story. The chart above from Iowa State shows the predicted heat index this week from multiple models; the combination of mid to upper 80s and a dew point near 70F may create a heat index in excess of 95F today, Thursday and Saturday.

Flashes of Mid-July. A bloated heat-pump high pressure ridge is forecast to temporarily stall over the central USA; keeping us unusually warm and sticky into the weekend. NOAA's GFS model (above) pulls cooler, drier air into Minnesota in time for Labor Day; the ECMWF (European) hints that the push of cooler air may stall to our north and west, keeping us on the uncomfortable side of the front into early next week.

Entering Another Wet Phase. The 7-Day rainfall potential map from NOAA prints out over 1.5" of rain for roughly the northwest half of Minnesota, with some 3-4" amounts near International Falls by next Monday evening. Meanwhile the soggy remains of "Erika" continue to douse Florida and coastal Georgia with swarms of T-storms capable of additional flash flooding.

Model Hiccup? The 4 KM NAM (or WRF) model prints out well over 1" of rain by this evening, which is possible, but a low probability risk. The leading edge of steamy air may set off a few isolated T-storms from tonight into Wednesday, and then we dry out much of Thursday and Friday. Source: Iowa State.

September Climate Calendar. Average high drop from 77F on September 1 to 65F by September 30. That said, September is often a spectacular month, with lower humidity (in theory), fewer T-storms and a better chance of salvaging outdoor activities. Then again there are exceptions to every rule. Check out the climate calendar here, courtesy of the Minnesota DNR.

Sweltering Summer Has Climatologists Sweating. We've been relatively lucky this summer in Minnesota with an absence of extended hot streaks. The rest of the Northern Hemisphere hasn't been quite so fortunate. Here's a clip from the German edtion of The Local: "Heat over 40 degrees, weeks without rain, sudden storms and flash floods – in the summer of 2015 Germany experienced all these things. Are these extremes set to become the norm? “It fits the description [of global warming],” says Peter Hoffmann from Potsdam's Institute for Climate Research (PIK). And the weather could become more intense meaning more heat waves and an increase in sudden localized storms. In the future we can expect more days without rain and and then extreme downpours in a short time span. says Hoffmann. “We should prepare for both extremes...”

New Study Reveals The Possibility of Hurricanes "Unlike Anything You've Seen in History". Chris Mooney at The Washington Post has the story; here's the intro: "Last week, the nation focused its attention on the 10-year anniversary of Hurricane Katrina, the most destructive hurricane in U.S. history. As bad as the storm was, though, it wasn’t the worst storm that could have possibly hit New Orleans. That’s true of many, many other places, too. And now, in a new study in Nature Climate Change, Princeton’s Ning Lin and MIT’s Kerry Emanuel demonstrate that when it comes to three global cities in particular — Tampa, Fla., Cairns, Australia, and Dubai, United Arab Emirates — there could come a storm that is much worse than anything in recent memory (or in any memory)..." (File image of Super Typhoon Haiyan, which generated sustained winds estimated at 180-200 mph before strike the Philippines in early November, 2013.

10 Years After Katrina, Miami Very Vulnerable to Hurricane Hit. Here's a clip from a video and story at NBC News: "...Of the 20 large (global) cities that people talk about as being highly at risk for coast storms, about eight of them are on the American coast: the East Coast and the South coast," said Greg Baecher, a professor of engineering at the University of Maryland. "If a Katrina directly hit Miami, you are talking about damages that could be several multiples of what happened in New Orleans," Baecher told CNBC. "First, you have the size of the city, and the fact that there is nothing between the coast and the ocean..."

Billions Spent on Flood Barriers, But New Orleans Still a "Fishbowl". The number I heard from PBS News Hour was $14 billion, which is a staggering sum. It doesn't help that the city is actually situated below sea level. Will the new and improved (and wildly expensive) levees and storm barriers hold? Only time will tell. Here's an excerpt from WUNC: "...Flood protection" is a loaded term. The Army Corps of Engineers prefers to call it a "risk reduction system." The new system is designed to withstand a 100-year hurricane or a storm that has a 1 percent chance of occurring each year, and to significantly reduce flooding from a 500-year cyclone. "We changed that lexicon after Hurricane Katrina because we didn't want the public to be deluded into thinking that they were protected, that they're safe, that once we have a system that was complete they were relieved from any risk of flooding," says Mike Park, the Corps' chief of operations in New Orleans..."

Apple's Ad-Blocking is Potential Nightmare for Publishers. Here's an excerpt from The Wall Street Journal: "...Apple’s Safari desktop browser has supported ad-blocking software for years. But the company is preparing to allow similar functionality in the mobile version of Safari in iOS 9, the next version of its operating system, which is expected to be released next month. The “beta” version that some people are testing includes the ad-blocking capability. For sites that support themselves with advertising, the reason for their heartburn is clear: they are already struggling to monetize their growing mobile audiences. If millions of iPhone and iPad users can easily activate ad blocking, that will translate to fewer ads to sell and likely less revenue..."

Soul Searching in TV Land Over the Challenges of a New Golden Age. 400 new TV shows this year? My clones and I are enjoying each and every one of them! Here's a clip from The New York Times: "...There’s a malaise in TV these days that’s felt among executives, viewers and critics, said Mr. Landgraf, the chief executive of FX Networks. And it’s the result of one thing: There is simply too much on television. The glut, he said at a Television Critics Association media event earlier this month, has made it hard to “cut through the clutter and create real buzz” and has presented “a huge challenge in finding compelling original stories and the level of talent needed to sustain those stories.” On the face of it, the assertion seemed absurd..."

Why Former 49er Chris Borland Is The Most Dangerous Man in Football. Here's an excerpt from a remarkable story at ESPN: "...Borland has consistently described his retirement as a pre-emptive strike to (hopefully) preserve his mental health. "If there were no possibility of brain damage, I'd still be playing," he says. But buried deeper in his message are ideas perhaps even more threatening to the NFL and our embattled national sport. It's not just that Borland won't play football anymore. He's reluctant to even watch it, he now says, so disturbed is he by its inherent violence, the extreme measures that are required to stay on the field at the highest levels and the physical destruction he has witnessed to people he loves and admires -- especially to their brains..."

"Gadget Allergy" Disorder Recognized in French Courts. Just when you thought you had seen everything; here's a clip from a story at WIRED: "...Marine Richard, who lives in the mountains of southwest France to avoid electronics, said that the ruling was a "breakthrough" for people who claim to suffer from Electromagnetic Hypersensitivity (EHS). Sufferers say they experience symptoms including headaches, nausea, tiredness and 'tingling' sensations when exposed to electromagnetic radiation from cellphones, WiFi or even just batteries, screens and other elements of technology which give off electromagnetic radiation..."

The American Lawn: A Eulogy. I'm not ready to give up my lawn just yet, although if I lived in water-starved California I'd probably think different. Here's an excerpt from Citylab at The Atlantic: "...And the lawn—its cause furthered by the Levittown model and the introduction of the motorized lawnmower and the Haber-Bosch fertilizing process and the mid-century’s faith in the easy virtues of conformity—spread. It was relatively cheap to install—see the seeds nicknamed “contractor’s mix” for their popularity among developers as a quick-and-easy way to landscape. A verdant metaphor for the new national highway system, it unified the country, visually if not politically. And symbolically if not actually. During a time of upheaval, the lawn suggested a sense of structure and calm...."

Climate Stories....

Climate Change: 2015 Will Be Hottest Year on Record "By a Mile" Experts Say. Here's the intro to a story at The Independent: "Climate scientists are predicting that 2015 will be the hottest year on record “by a mile”, with the increase in worldwide average temperatures dramatically undermining the idea that global warming has stopped – as some climate-change sceptics claim. Even though there are still several months left in the year to gather temperature readings from around the world, climate researchers believe nothing short of a Krakatoa-sized volcanic eruption that cuts out sunlight for months on end can now stop last year’s record being beaten..."

Obama Plays Defense on Climate Change Ahead of Alaska Trip. Caught between a rock and an oily place. Here's a clip from a video and story at NPR: "...He added, "I share people's concerns about off-shore drilling." But, Obama pointed out, he is trying to balance domestic economic concerns as he tries to push the world to wean itself off oil. "Our economy still has to rely on oil and gas," Obama said. "And, as long as that's the case, I believe we should rely more on domestic production than on foreign imports...."

Obama's Arctic Trip Comes as Climate Change Builds as 2016 Issue. Here's an excerpt from The Wall Street Journal: "President Barack Obama’s trip to Alaska’s Arctic on Monday likely will reverberate much farther south, on the 2016 presidential campaign trail, where global warming is expected to emerge as a key issue. His visit to the North Pole region, the first ever for a sitting president, coincides with a growing public consensus that the earth is heating up and that humans have something to do with it. A July report from the Pew Research Center found that 72% of American adults say there is “solid evidence” of global warming..."

Citi Report: Slowing Global Warming Would Save Tens of Trillions of Dollars. Here's a clip from a story at The Guardian: "...This conclusion soundly refutes the main argument against climate action – that it’s too expensive, with some contrarians even having gone so far as to claim that cutting carbon pollution will create an economic catastrophe. To the contrary, the Citi report finds that these investments will save money, before even accounting for the tremendous savings from avoiding climate damage costs. What about those avoided climate costs? As shown in the bottom left corner of the above figure, the difference in climate damage costs between low (1.5°C) warming and high (4.5°C) warming scenarios could be as high as $50 trillion. Even moderate (2.5°C) warming could cost $30 trillion less than a business-as-usual high global warming scenario..." (Graphic credit: NOAA NCDC).

Call It What It Is: A Global Migration Shift from Climate, Not a Migrant or Refugee Crisis. Alarmist hype? There's compelling evidence that historic drought in Syria let to the dislocation and social unrest that planted the seeds for the rise of ISIS. Dry areas are getting drier; the Middle East and northern Africa is forecast to become even drier, and perpetual drought and water/food shortages may have unpleasant ramifications going forward. Here's an excerpt of an Op-Ed at Huffington Post: "...While news organizations and policymakers around the world wrestle with calling displaced persons "refugees" or "migrants"or "asylum-seekers," a far more dangerous precedence of denial over a looming global shift of populations largely from climate change is taking place. There is not a migrant or refugee crisis. We're in the midst of a global migration shift. While its unrelenting realities of forced displacement, whether from war, persecution or economic despair originate from disparate causes, they all share a singular fact: The nascent stages of this historical migration shift require long-term planning, not short-term designation..."

How Will Climate Change Affect Your Livelihood? If you're a farmer it's already impacting your business with more volatile swings in temperature and moisture (and much heavier summer rains already showing up in the data). Here's an excerpt from Business Insider: "As the reality of global warming starts to hit home, people may ask: "How will it affect my livelihood?" Well, that depends.  On your profession, your age, and exactly where you live, among other things.  Here, then, are a few scenarios for a climate-altered future, when rising temperatures are closing in on the threshold of two degrees Celsius (3.6 degree Fahrenheit) above pre-industrial levels which scientists warn we should not cross..."

Warming's Recipe for Baked Alaska: Trillions of Tons of Glaciers Gone, Millions of Acres Burned. Here's an excerpt from AP and US News: "...More than 3.5 trillion tons of water have melted off of Alaska's glaciers since 1959, when Alaska first became a state, studies show — enough to fill more than 1 billion Olympic-sized pools. The crucial, coast-hugging sea ice that protects villages from storms and makes hunting easier is dwindling in summer and is now absent each year a month longer than it was in the 1970s, other studies find. The Army Corps of Engineers identified 26 villages where erosion linked to sea ice loss threatens the communities' very existence. Permafrost is thawing more often as the ground warms, so as the ground oozes, roads, pipelines and houses' foundations tilt and shift — sometimes enough to cause homes to be abandoned..."

Photo credit above: "In this March 29, 2006 photo, a skier poses for a photograph on Portage Lake in front of Portage Glacier, about 50 miles south of Anchorage, Alaska. The Portage Glacier, which is a major Alaska tourist destination near Anchorage has retreated so far it no longer can be seen from a multimillion-dollar visitors center built in 1986. President Obama leaves Monday, Aug. 31, 2015 for a three-day visit to the 49th state in which he will speak at a State Department climate change conference and become the first president to visit the Alaska Arctic. There and even in the sub-Arctic part of the state, he will see the damage caused by warming, damage that has been evident to scientists for years." (Evan R. Steinhauser/Anchorage Dispatch News via AP, File).

What's A Glacier Visitor Center With No Glacier? Yale Climate Connections has a post and interview with St. Louis businessman Larry Lazar, who went from climate skeptic to acknowledging the science after a visit to Alaska; here's an excerpt: "...A photograph from the 1990s proves the glacier could once be seen from the visitor’s center. But just a decade later, Lazar’s family had to take a long boat ride up the lake to find it. “This made it very clear that global warming is real. Unfortunately, that’s not what I had been hearing on radio and TV back home in St. Louis. I reflected on this a great deal on the return trip. When I got home, I turned off the radio and TV and I opened some books. I started with James Hansen’s Storms of My Grandchildren and continued from there. The more I learned, the more aha moments I had — many of them alarming, which is why I speak out today to protect the climate...”

How To Talk About Climate Change So People Will Listen. Somewhere between the apocalyptic tales of gloom and doom and the "no worries!" attitude of perpetual deniers lies the truth; here's an excerpt from The Atlantic: "...According to Forbes, the world has 1,645 billionaires, several hundred of them in nations threatened by climate change. If their businesses or homes were at risk, any one of them could single-handedly pay for a course of geo-engineering. Is anyone certain none of these people would pull the trigger? Few experts think that relying on geo-engineering would be a good idea. But no one knows how soon reality will trump ideology, and so we may finally have hit on a useful form of alarmism. One of the virtues of Keith’s succinct, scary book is to convince the reader that unless we find a way to talk about climate change, planes full of sulfuric acid will soon be on the runway."
