Summer On Hold Early Next Week - Coolest MLB All-Star Game on Record?

"July-tober"

Not much surprises me anymore. Numbing cold followed by record rains as weather patterns slow and our climate becomes more volatile? A 4th of July blizzard would have gotten my attention.

Welcome to the "new normal".

Even so next week's weather map made me do a double-take. During what is typically the hottest week of the year a hunk of October-like air will hurtle south. Minnesotans will be wandering around in light jackets & sweatshirts on Monday and early Tuesday, mourning the (temporary) death of summer.

1816 was "A Year Without a Summer", due to low solar activity and volcanic eruptions. Heavy snows were reported into June; ice "thick enough to support the full weight of a duck" into July over New England.

This summer? Not quite that extreme, but the jet stream is still misbehaving and I suspect it's related to rapid warming of the Arctic. We'll see.

A comfortable Thursday gives way to a few T-storms Friday, the wettest day in sight. Soak up 80s Saturday because an autumn-like cool front arrives late Sunday. By Monday "highs" may hold in the 50s north, 60s south with a discernible whiff of crisp mid-summer wind chill.

Just when you thought things couldn't get any stranger around here.


* Monday 1 PM temperature anomalies across the USA courtes of Weather Bell. Temperatures may be 26 F. cooler than average across much of Minnesota; as much as 30-34 F. warmer than normal across western Canada. More crazy extremes.

Reinforcing Tired Stereotypes. "Oh, you're from Minnesota. It's really cold up there, huh?" Raise your hand if you've ever heard that before. Plan on hearing more of it after Tuesday's MLB All-Star game, which may wind up being the coolest on record, with gametime temperatures in the 60s under a mostly clear sky. Light jacket or sweatshirt weather. But not as chilly as Monday, when 10-20 mph winds, coupled with ragged clouds and PM showers will make you SWEAR it's October. Something to look forward to. A meager warm front sparks a few showers and T-showers tonight into Friday morning. Summer takes a siesta next week.


Risk of a Smoky Sunset. Visible satellite imagery Wednesday showed a plume of smoke sweeping across the Dakotas, from wildfires blazing over Canada's Northwest Territories. Some of that smoke may reach Minnesota in the coming days, giving the sky a milky, hazy cast - possibly sparking an extra-red sunrise or sunset.

Tornado Alley Migration? Traditional Tornado Alley runs from Texas to Iowa, but in recent years NOAA SPC has issued the most Tornado Watches for southern Alabama and Mississippi, the same area that has the highest tornado concentration and death toll. Not quite what I was expecting, and it's the topic of today's first Climate Matters segment.


Steps To Reduce The Risk of Tornado Damage in Commercial Structures. Here's an excerpt of an interesting story at DisasterSafety.org that caught my eye: "...The strongest category of tornadoes can generate maximum wind speeds of greater than 250 mph, which is enough to destroy most buildings and structures in their path. These maximum wind speeds generate forces that are about twice as large as those generated by the strongest hurricanes. Only a few specialty buildings are designed to withstand the direct impact of a severe tornado. However, well engineered, large and tall commercial structures are not likely to suffer structural collapse. For smaller commercial structures, good construction choices can give added protection and increase the likelihood that at least part of the structure will remain standing to provide shelter. Buildings that have been strengthened in critical areas and particularly at connection points, such as between the roof and walls and walls and foundation, would have a good chance of surviving intact or with minor cosmetic damage if subjected to the outer edges of a tornado..."


Severe Storm Capital of the USA Since 2003: Asheville, North Carolina? I know, I did a double-take too, and 10 years may not be a long enough time to derive any meaningful statistical trends, but the Asheville area receives nearly 40 days/year, on average, with a tornado, severe wind storm or large hail within 25 miles of the city, according to NOAA SPC. That compares with 25 in Atlanta, 21 in Dallas and Denver, 10 in Chicago and roughly 16 in the Twin Cities. L.A. sees an average of 4 severe weather days, with only 1 in the Bay Area and San Diego. Sign me up. Source: NOAA SPC.


Severe Thunderstorm Winds Days Per Year Since 2003. The same trends are evident with thunderstorm generated straight-line winds, with a peak frequence over the western Carolinas and the Tennessee Valley. On average the Twin Cities have picked up an average of 8-9 severe wind days/year since 2003.


Want To Avoid Hail? Move North. Cool breezes off Lake Superior inhibit the largest, hail-producing thunderstorms much of the summer season: 1-3 large hail days a year for Duluth, on average, but less than 1 for much of the North Shore and Minnesota Arrowhead. That compares with 3-6 large hail days for Minneapolis - St. Paul, and over 8 hail days/year for Kansas City and the Denver area.


The Severe Weather Capital of the USA Since 2003 is....North Carolina? When, exactly, did that happen? The data set isn't very long (since 2003), but looking at tornadoes, large hail and damaging winds Asheville, North Carolina sees more than 3 times more "severe weather days" during an average year than Dallas or Wichita. That's the subject of a second Climate Matters segment: "40 days a year of severe weather makes..... Asheville, NC the severe weather capital of the United States? It's true. The Carolinas see almost 40 days a year with hail and wind gusts over 50 mph. That's a bit of a head scratcher."


Be Prepared! What To Do Before, During, And After a Hurricane. RedOrbit has a timely article with some useful information and links; here's an excerpt: "From June 1 to November 30 of each year, the Atlantic hurricane season flexes its muscles. In an effort to help keep people alive and safe, the Centers for Disease Control and Prevention (CDC) keeps a Hurricane Preparedness website that is full of great information to help with hurricane health and safety. The CDC provides important tips to help before, during, and after a hurricane. Before: The first tip is to prepare for a hurricane. If you live in a place that could be hit, it is best to prepare now rather than wait for a hurricane to be imminent. Before a hurricane, the CDC identifies two steps: make a plan and get supplies. In making a plan, the CDC gives these readiness suggestions..." (Hurricane Irene file photo: NASA).


Why New Orleans' Katrina Evacuation Debacle Will Never Happen Again. Next City has an interesting story focused on what New Orleans officials learned in the wake of Superstorm Sandy; how they are much better prepared for the next, inevitable hurricane. Here's an excerpt: "In New Orleans, evacuation requires decisions that must be made early before traffic builds, motels fill up, roads flood, or winds reach dangerous levels. In 2005, when Katrina loomed in the Gulf, most New Orleanians did leave town, but roughly 100,000 were left behind. Many lacked a car or money for transportation, or had special needs that made evacuation impossible. Others were stranded because they practiced “vertical evacuation,” staying with family that lived on higher ground or renting hotel rooms in buildings that had proven safe in the past. “We will never do that again,” said Lt. Col. Jerry Sneed, the city’s deputy mayor of Public Safety and Homeland Security..."


What's The Difference Between a Hurricane, Cyclone and Typhoon? Of course they are one in the same, but some of the classifications are slightly different, as explained at wsav.com; here's a clip: "...To be classified as a hurricane… typhoon or cyclone… a storm must reach wind speeds of at least 74 miles per hour. If a hurricane's winds reach speeds of 111 miles per hour… it is then upgraded to a major hurricane. If a typhoon hits 150 miles per hour then it becomes a super typhoon..."


I Was a TSA Agent, And The New Airport Cellphone Rules Wouldn't Stop an iBomb. Well this is reassuring as I board the plane (clutching my Bible tightly). Here's an excerpt from The Guardian: "...This is the real conundrum that accompanies most post-9/11 airport security rules: the logic behind them is a race to the bottom. Consider...

  • If a group of terrorists is clever enough to pack explosives inside a laptop to make them undetectable by current technology, wouldn't they be clever enough to devise an explosive laptop that can do all of this ... and still appear to power up?
  • If US intelligence next announces that terrorists have become clever enough to engineer the faux-power laptop bomb, and passengers are then required to prove their laptops can connect to airport WiFi, how long until murky intelligence warns of a hotspot-enabled iBomb?..."

Decades-Old Forgotten Vials of Smallpox Found In Storage Room. So don't sweat the thundershowers tomorrow OK? Here's a clip from an AP story at Huffington Post: "A government scientist cleaning out an old storage room at a research center near Washington made a startling discovery last week — decades-old vials of smallpox packed away and forgotten in a cardboard box. The six glass vials were intact and sealed, and scientists have yet to establish whether the virus is dead or alive, the Centers for Disease Control and Prevention said Tuesday. Still, the find was disturbing because for decades after smallpox was declared eradicated in 1980, world health authorities said the only known samples left were safely stored in super-secure laboratories in Atlanta and in Russia..."

Seoul's Eccentric Mayor is Building Hotels for Insects. Yes, Insects. Great! One less city on my travel bucket list. GlobalPost has the curious details; here's a clip: "As part of its greening efforts, Seoul is embarking on a campaign to establish 27 “insect hotels” in parks and public areas, offering the bug population a refuge in this gray, cyberpunk Asian mega-city, protecting them against the spread of insecticide. City officials are enthusiastic. “Seoul was developed very fast, and it wasn't regulated. We don't have a diverse species of bugs,” explained Yang Gyoung-gyu, a city environmental advisor. “The effect of the insect hotel is to expand the diversity of species...”


California Screaming. The tech industry made the Bay Area rich. Why do so many residents hate it? Nathan Heller has an interesting read at The New Yorker; here's an excerpt: "...Many people in San Francisco today worry that the tech industry is behaving like Coyote, professing to nurture and provide while actually hoarding. San Francisco has a real-estate shortage. Some speculators, looking to capitalize on growing demand, have started circumventing rent control using buyouts: lumps of cash given if long-term tenants leave. Others have invoked a 1986 California law known as the Ellis Act, which permits evictions when landlords want to go out of business permanently..."


"Cloud" Brings Thunder and Lightning Inside Your Home. I'm going to need a few of these, especially in the guest bathroom, right above the toilet. Details at gizmag.com: "Cloud, by New Zealand-based designer Richard Clarkson, is an interactive lamp designed to mimic a thundercloud. It brings the outside inside, providing an audiovisual show that looks and sounds like thunder and lightning ... but thankfully rain isn't included in the package..."


Student-Designed Device Reduces Gas Lawnmower Air Pollution by Over 90 Percent. Yes, our kids will save us from ourselves; here's another example of the kind of innovation we're going to need from Gizmag: "Gas-powered lawnmowers are notorious polluters. According to the US Environmental Protection Agency, running a new gas mower for one hour produces as much air pollution as would be generated by 11 typical automobiles being driven for the same amount of time. Switching to an electric or reel mower is certainly one option, but for those applications where it's gotta be gasoline, a team of engineering students from the University of California, Riverside are developing another: an attachment that they claim reduces noxious emissions by over 90 percent..."


When "Sprinkles" are Newsworthy. My friend, Bill Stein, lives in the San Francisco Bay Area, and sent me this tweet yesterday. Yes, in a severe, historic drought a few drips from the sky constitute "breaking news". His comments: "I thought you might get a slight laugh out of the attached pic. I raced to grab a photo of sprinkles here in Pleasanton and tweeted it to the Bay Area NWS. They retweeted the picture and the next thing I know San Fran's NBC station wants to run the picture. Of sprinkles!!! (Though Stockton, CA actually set a record with .01" of rain today.)"

Climate Stories....

Global Warming Requires More Frequent Rethink of "Normal" Weather: UN. No kidding. As the weather becomes more volatile, responding to more energy and heat in the atmosphere-ocean-cryosphere, we're going to see more erratic swings in temperature and moisture. Here's an excerpt from Reuters: "The baseline for "normal" weather used by everyone from farmers to governments to plan ahead needs to be updated more frequently to account for the big shifts caused by global warming, the U.N.'s World Meteorological Organization said on Wednesday. The WMO's Commission for Climatology believes rising temperatures and more heatwaves and heavy rains mean the existing baseline, based on the climate averages of 1961-90, is out of date as a guide, the WMO said in a statement. "For water resources, agriculture and energy, the old averages no longer reflect the current realities," Omar Baddour, head of the data management applications at the WMO, told Reuters..."


Climate Change: What Are The Risks to Corporations? Fortune has the details; here's an excerpt that caught my eye: "Extreme weather events appear to be getting more severe and more frequent, as the recent drought in California and floods in Europe reminded us. Weather events accounted for 90% of natural catastrophe losses in 2013, causing over $120 billion of losses, according to reinsurance company Munich Re. In 2012, the overall effect of climate events on the US and European economies is estimated at more than $5 trillion for each region, or over 30% of their GDP. The investment community – along with regulators – has woken up to this threat. It is demanding more information from companies about their exposure to climate events, as well as the prospective cost of their carbon emissions..."


Saving Water in California. California may be facing a slow-motion water disaster if El Nino-driven rains don't arrive next winter (which is no sure bet). Here's a clip of an Op-Ed from The New York Times Editorial Board: "...California is in the third year of its worst drought in decades. But you wouldn’t know this by looking at how much water the state’s residents and businesses are using. According to a recent state survey, Californians cut the amount of water they used in the first five months of the year by just 5 percent, far short of the 20 percent reduction Gov. Jerry Brown called for in January. In some parts of the state like the San Diego area water use has actually increased from 2013. Without much stronger conservation measures, the state, much of which is arid or semiarid, could face severe water shortages if the drought does not break next year..." (Image above: ThinkStock).


The Climate Optimists. It's tempting to rail against Big Government. Until a freak storm levels your home, or flooding paralyzes your community, or a withering drought brings business as usual to a screeching halt. Then the free-market advocates usually come crying to the very same Big Government to bail them out and clean up the mess. Which will happen with greater frequency if climate scientists are correct. According to Will Oremus at Slate attending a climate denier conference in Las Vegas, conservatives have a new line on climate change: "It's real, but it's nothing to worry about!" Here's an excerpt: "...It’s tempting to find irony in the spectacle of hundreds of climate change deniers staging their convention amid a drought of historic proportions. But, as the conference organizers are quick to tell you, they aren’t actually climate change deniers. The majority of this year’s speakers readily acknowledge that the climate is changing. Some­ will even concede that human emissions are playing a role. They just think the solutions are likely to be far worse than the problem..."
