“Hot Front” (and America’s most hurricane-vulnerable cities)
America’s Most Vulnerable Hurricane Cities? Not surprisingly, two of the top 5 are in Florida. Tampa/St. Pete has the dubious distinction of being #1. Details from Climate Central below.
Weather Nugget: “The last drop of rain in Flagstaff was on April 26th, a dry spell of 40 days so far. With the driest time of year upon us, this could go on for quite a while!”
“For the insurance industry it means massive exposure to property damage and business losses from storms, wildfires, floods and droughts. For the electric power and oil and gas sectors it means supply disruptions and disabled infrastructure. The new report also details comparable risks in the apparel, mining and tourism sectors. In short, climate change is bringing with it a whole new world of risk for businesses, investors and the economy — risks that many companies are under obligation to disclose.” – from a Huffington Post article below.
Photo Of The Day: “Montana Supercell”. My thanks to Roger Hill for sharing this remarkable photo of a tornado near Stanford, Montana – one of the most amazing pics I’ve seen in a long time. Details via Facebook: “Ok, this is getting crazy! So many fantastic structured supercells, and today (June 5th) was no exception! We intercepted an HPish storm southeast of Stanford, MT and moved northward as it approached Denton. Off to the south, the structure came into view and low and behold, somewhere between Moccasin and Denton this tornado touched down. Partially rain wrapped at times, we were fortunate enough to look down the notch from the northwest and see this insane sight! I have better structure shots I will put up in another day or so. Structure was slightly enhanced to bring out the tornado.”
An Awesome Sight. Professional photographer Sean R. Heavey captured this awe-inspiring shot near Big Sandy, Montana Tuesday, complete with wall cloud below and lumpy, cumulonimbus mammatus clouds dangling from the thunderhead anvil above. Check out his photos here.
NexSat. I’m a fan of the Naval Research Lab site, which has created some new and novel ways to display visible and infrared (temperature derived) satellite imagery from NOAA. The image above was taken at 9:30 pm yesterday, showing strong/severe (tornado-producing) storms from the Denver area into the central Plains.
Close Call. Late Wednesday came reports of a weak tornado near DIA, Denver International Airport. As many as 4-5 separate tornadoes were spotted over the far southeastern suburbs of Denver Wednesday evening, in Arapahoe County. Click here to see the latest list of NOAA storm reports.
Top 5 Most Vulnerable U.S. Cities To Hurricanes. Climate Central meteorologist Andrew Freedman has a terrific article that summarizes the threat to America’s most vulnerable metro areas; here’s an excerpt: “The 2012 Atlantic Hurricane Season is officially underway, and while Hurricane Katrina has tended to fade from memory, New Orleans isn’t the only major U.S. city at risk, although it remains extremely vulnerable. As Hurricane Irene demonstrated in 2011, weaker hurricanes can also do significant damage in places that are not used to experiencing such storms. Many American coastal cities are essentially sitting ducks to hurricanes, with millions of Americans living at water’s edge, exposed to high winds and flooding. Some of these communities, like New Orleans and Houston, have experienced powerful storms during the past decade. Others, like Miami and Tampa, have been spared the brunt of landfalling storms during recent hurricane seasons.”
New Mexico Smoke Plume From Space. NASA’s Earth Observatory captured this photo of the southwestern USA Tuesday, showing the pall of smoke from the (record) New Mexico Whitewater-Baldy blaze being swept south and west, toward Phoenix and Baja Mexico.
Transit Of Venus. In case you missed it – here’s an amateur video of Venus passing in front of the sun Tuesday evening, captured by Josh Dowell, via YouTube: “Here is an amateur video shot of the Venus Transit. Shot on June 5th, 2012 with a Sony AVCHD Handycam. The camcorder itself could not view the sun like this I had to break some nice sunglasses to use the lens to block out the sunlight.”
“Ask Paul” Weather-related Q&A
Hello – what is called when the clouds move away from the lake? And why does in happen?
I was watching the Midwest (Great Lakes) satellite for the Minnesota weather (thunderstorm), yet I noticed the cloud cover pulling back from Lake Michigan. Is that due to winds coming from the north/northeast, and/or also the water on Lake Michigan is cooler (and drier) than the air on land?
Paul (may I call you Paul?) – you sent along a great example of lake effect clouds, a sort of “reverse-lake-effect” during the summer months. You have the right idea: water takes much longer to heat up than land. Great Lakes water temperatures are routinely 20 degrees cooler than surrounding land temperatures, which heat up rapidly with the sun so high in the sky in June. As air heats up it rises, allowing stable, lake-cooled air to push 5-50 miles inland. These miniature cool fronts pushing away from cooler lakes can set up boundaries capable of firing off showers and T-showers. This “sea-breeze” effect triggers late-day T-showers like clockwork many summer days across Florida. It all ties back to differential heating of land and water. In November the process reverses – lake water is warmer than chilly Canadian, heating the air from below, sparking lake-effect clouds and (snow) showers downwind of the Great Lakes. Great question!
Time For Your Close-Up. Here is Wednesday’s NASA MODIS 250 meter close-up of the southern tip of Lake Michigan. Air temperatures shot up into the low to mid 70s, heating the air above the land, causing fair weather cumulus to sprout 20 miles inland. But lake water temperatures off Navy Pier are still in the mid to upper 50s, and by mid afternoon that lake-cooled air had been pulled inland – resulting in a cloud-free zone near the lake.
7 Ways To Disrupt Your Industry. If you’re not paranoid, you’re not paying attention, right? Here’s an excerpt of an excellent article from Fast Company on steps you can take to to prepare yourself, and your company, for inevitable change: “Massive disruption is coming, and the only question is whether your firm is going to cause it or fall victim to it. Disruption is not easy–either to create or to confront. We have no illusions about that. But in the spirit of helping established firms best serve their customers, we offer seven ways your firm could disrupt its own industry, raising the standards of customer experience and creating new opportunities for growth:
1) Totally eliminate your industry’s persistent customer pain points.
Each industry has practices that drive customers crazy.
Technology providers drive customers crazy with technical support that often requires long waits on hold and hopelessly complex interactions (“Just find the serial number on the back of your device and type that into the space provided along with your IP address and the exact wording of the error message you encountered”).”
“Orsos Island” – The Smallest Floating Island Yet In A Fast Growing Market. Who are these people, and why can’t I be related to one of them? Good grief. For a new level of wretched excess, check out this story from gizmag.com: “The Wally Island was a 99 meter (325 feet) “gigayacht” design that dwarfed the vast majority of luxury megayachts and reconceived the yacht as a floating personal island, a mobile address that can be used as a home, an entertaining space or even a moving exhibition or show space. At an estimated US$200 million, the Wally Island was not for the common man, but the concept appears to have ignited a flurry of activity in the marine industry, with these new designs all more focused on a comfortable movable living space framed as a floating island more than a boat.”

What is Heat Index?
“If you saw a heat wave, would you wave back?” asked humorist Steven Wright.
Let me ponder that one.
U.N. Report Warns Environment Is At Tipping Point. Here’s an excerpt from a story from seattlepi.com: “RIO DE JANEIRO (AP) — The earth’s environmental systems “are being pushed towards their biophysical limits,” beyond which loom sudden, irreversible and potentially catastrophic changes, the United Nations Environment Program warned Wednesday. In a 525-page report on the health of the planet, the agency paints a grim picture: The melting of the polar ice caps, desertification in Africa, deforestation of tropical jungles, spiraling use of chemicals and the emptying out of the world’s seas are just some of myriad environmental catastrophes posing a threat to life as we know it.”

Extreme Weather Is The New Reality. Here’s a snippet of a Huffington Post article from the President of Ceres: “There’s been a nasty change in the weather of late, and for businesses the forecast is simple: be prepared. In 2011, extreme weather caused more than $148 billion in economic losses, and $55 billion in insured losses globally. A major chunk of those insured losses — more than $30 billion — were in the U.S. where 14 severe weather events caused losses of more than $1 billion each, far more than in any previous year. We’ve just lived through the warmest decade on record, seen unprecedented flash storms and flooding and watched as Texas suffered through the worst drought in its history. Just a normal variation in the weather? “No,” is the overwhelming scientific consensus. Human activity is changing the climate, and the climate is changing the weather. Buckle up. It’s going to be a wild ride. And virtually every business in every sector of the economy is vulnerable.”
Virginia’s Dying Marshes And Climate Change Denial. Details from The BBC: “Dying wetland trees along Virginia’s coastline are evidence that rising sea levels threaten nature and humans, scientists say – and show the limits of political action amid climate change scepticism. Dead trees loom over the marsh like the bones of a whale beached long ago. In the salt marshes along the banks of the York River in the US state of Virginia, pine and cedar trees and bushes of holly and wax myrtle occupy small islands, known as hummocks.”

- Welcome to the WeatherNation blog. Every day I sift through hundreds of stories, maps, graphics and meteorological web sites, trying to capture some of the most interesting weather nuggets, the stories behind the forecast. I’ll link to stories and share some of the web sites I use. I’m still passionate about the weather, have been ever since Tropical Storm Agnes flooded my home in Lancaster, PA in 1972. I’ve started 5 weather-related companies. “EarthWatch” created the world’s first 3-D weather graphics for TV stations – Steven Spielberg used our software in “Jurassic Park” and “Twister”. My last company, “Digital Cyclone”, personalized weather for cell phones. “My-Cast” was launched in 2001 and is still going strong on iPhone, Android and Blackberry. I sold DCI to Garmin in 2007 so I could focus on my latest venture: WeatherNation. I also write a daily weather column for The Star Tribune startribune.
