NOAA Hurricane Prediction: Busier Than Average (will NOAA technical failures impact forecast accuracy?)

Ill-Timed Warm Front For Upper Midwest



My barber, Hurricane Heidi Rusch, was brutally blunt: “my clients are DISGUSTED by spring, Paul. They’re so sick of cool and wet they don’t even want to talk about it!” It’s been a tortured spring, and I’m keeping weather-expectations for the first unofficial holiday of summer low, hoping we might be pleasantly surprised.



Showers are likely tonight, a damp start Saturday with leftover clouds and highs stuck in the 50s. Grade: C-. Sleep in & see a movie. A few T-storms push across southern Minnesota Sunday – not an all-day rain, but have a Plan B for part of the day. A C+ day, but a few degrees milder. Memorial Day looks a bit better as a warm front lifts north; the best chance of T-storms early. Skies may brighten enough by afternoon for highs topping 70F. A solid B, and that’s grading on a curve.



Sticky, summerlike 80s return from the middle of next week into early June with swarms of T-storms; a few may be severe.



Today’s blog has an ominous hurricane prediction for 2013, along with news of some recent technology failures, including the GOES-13 weather satellite, which provides critical data for weather models and hurricane forecasts.



What can possibly go wrong?


“…This is an uphill battle, but I’m sure that the market will ultimately find a way to meet consumer demand. Many industries over the years — from the stagecoach builders and saddle makers to those who made the eight-track tape and the Sony Walkman — didn’t much like the change forced on them by the tide of history. Sooner or later, companies standing in the way today will face a similar choice: Meet consumers’ demands or become obsolete.” – Senator John McCain, arguing for a Television Consumer Freedom Act, in the Los Angeles Times below.

Atmospheric Tug-of-War. Warm air riding up and over a stubborn dome of cooler, drier air over the Great Lakes and Upper Midwest will spark periods of showers and T-storms over the weekend, the best chance of rain tonight and early Saturday; another round of showers and T-storms may push in on Sunday. Tomorrow looks like the foulest day; I don’t expect an all-day rain on Sunday or Monday, but rather hit or miss showers and T-showers. I’m just the messenger.

Moore Tornado Track Superimposed Over MSP Metro. A track from Edina to Maplewood? That’s what residents of Oklahoma’s southern suburbs, centered on Moore, enduring Monday afternoon, with patches of EF4 to EF5 damage (highlighted in red). Thanks to WeatherNation TV meteorologist D.J. Kayser for putting this story into local perspective. This is the kind of worst-case scenario that keeps me up at night. God-willing this will never happen, but we need to prepare for the worst, and hope for the best. An EF-4 can’t hit the metro? Tell that to residents of Fridley.

Moore, Oklahoma: Before And After The Tornado. This ESRI URL shows the implications of an EF-5 tornado, with devasting detail that I haven’t seen anywhere else.

Weather Service Systems Crumbling As Severe Weather Escalates. Failing weather satellites, NWS web sites going down in the south, the Chicago office of the NWS unable to issue severe storm warnings – what is going on? Here’s an excerpt from The Washington Post’s meteorologist Jason Samenow at The Capital Weather Gang: “As painfully obvious from the recent events in Oklahoma, tornado season is in full gear. Meanwhile, hurricane season is a week away.  Yet budget woes and multiple system failures at the National Weather Service in the past week, not to mention staffing shortages, are raising concerns that its ability to warn the public of hazardous weather could crack at any time. In the past 5 days alone, a telecommunications outage near Chicago made it difficult for NWS forecasters to issue warnings, a major weather satellite failed, the website for the entire NWS Southern Region went down, and a NWS official in tornado alley declined to launch a weather balloon citing budget concerns. These problems are symptomatic of insufficient funding and dated infrastructure, advocates for more generous NWS budgets say. What follows is an overview of the problems NWS has encountered, just since Sunday…”

The timing of these technical malfunctions and NOAA budget challenges and proposed furloughs is unfortunate…

NOAA Predicts Active 2013 Atlantic Hurricane Season. We’re in an ENSO-neutral period right now, no La Nina cooling or El Nino warming. El Nino also tends to turn on stronger winds in the tropics, which can deter tropical storm formation. It may be another very active season – here are a few excerpts from NOAA: “For the six-month hurricane season, which begins June 1, NOAA’s Atlantic Hurricane Season Outlook says there is a 70 percent likelihood of 13 to 20 named storms (winds of 39 mph or higher), of which 7 to 11 could become hurricanes (winds of 74 mph or higher), including 3 to 6 major hurricanes (Category 3, 4 or 5; winds of 111 mph or higher)….

Three climate factors that strongly control Atlantic hurricane activity are expected to come together to produce an active or extremely active 2013 hurricane season. These are:

  • A continuation of the atmospheric climate pattern, which includes a strong west African monsoon, that is responsible for the ongoing era of high activity for Atlantic hurricanes that began in 1995; 
  • Warmer-than-average water temperatures in the tropical Atlantic Ocean and Caribbean Sea; and 
  • El Niño is not expected to develop and suppress hurricane formation…”

Moore Tornado Recovery Efforts Signal Long Road Ahead. Here’s an excerpt from a story at Huffington Post: “…Early estimates indicate the tornado caused more than $2 billion of damage in Moore. Whole subdivisions in the fast-growing community of 56,000 people were destroyed. Authorities estimated that as many as 13,000 homes were damaged or destroyed and 33,000 people were affected – an especially traumatic toll for a city that had already suffered three other tornados since 1998. Two elementary schools were hit – one was leveled – by Monday’s tornado. Candelaria was one of seven children who perished at the Plaza Towers Elementary School, a one story building with barely a wall left standing. Altogether, 10 children were killed in the storm, including two infants…”

With authorities saying they have likely recovered all the bodies to be found beneath the rubble left by the Category 5 tornado Monday, the focus turned to the long and expensive path of recovering from one of the most catastrophic storms in Oklahoma’s history.” (Eric Thayer/The New York Times)

What Happens When A Tornado Hits? Here’s an excerpt of an interview I gave to Chris Hayes on MSNBC Monday evening, describing the dynamics of an EF4/EF5 tornado.

A Tornado Isn’t An Object, But Rather A Process. Tuesday night I had a chance ot explain how tornadoes form, the physics able to translate spin around a horizontal axis into a vertical axis (with the help of some great special effects). Here’s the video clip from “All In With Chris Hayes” on MSNBC. My segment is about 8:00 in.

When Tornadoes Are A Way Of Life. Here’s an excerpt of a radio interview I gave to Jennifer Ludden at NPR’s Talk of the Nation on Tuesday: “…I think one of the issues that we have in this country is a certain degree of tornado fatigue. Seventy percent of all tornado warnings, Jennifer, are false alarms, you know? Nobody wants to get caught with their Doppler down. So any time we see rotation in a thunderstorm, the temptation is to issue the warning. But in the process, we’re all kind of bombarded with warnings. You start to tune out. And on a day like yesterday, you need to break through the clutter and the apathy and the cry-wolf syndrome and shape people viscerally and emotionally. And the words that you chose – I think any sociologist will tell you the words you choose are critical in conveying that level of risk. At one point, Mike Morgan actually said: If you don’t have an underground shelter, this tornado is unsurvivable. Get into your vehicle, try to drive away – which you never, ever hear. And yet, that was the magnitude of the tornado threat yesterday. The problem is with tornados, we don’t know right away if it’s an EF1 or an EF4...”

Tornadoes And Urban Sprawl: How Long Until A Major City Is Hit? Oklahomans know exactly what to do when a major tornado is approaching, living at Ground Zero of Tornado Alley. But what happens when a similar (extreme) tornado hits a major city or densely populated suburb? We’re not even close to being ready for that scale of weather disaster. Here’s a link to a video from WeatherNation TV: “Meteorologists Paul Douglas and Susie Martin look at the severe threat for the coming days, as well as the statistics and the role urban sprawl has when it comes to the risk of a strong tornado hitting a major city.

Lessons From Moore Tornado Disaster. In today’s edition of Climate Matters I take a look at some of the implications of the Moore EF-5 tornado, including situational awareness, multiple information safety nets, and why you need to REALLY pay attention the next time a “Tornado Emergency” is issued for your area.

The Rise Of DIY Tornado Shelters. Do you really need to spend thousands of dollars to retrofit a closet into a steel and concrete-reinforced “safe room”, able to withstand even an extreme tornado? There may be some things you can on your own. Here’s an excerpt of a timely story from “…Homes without storm cellars or basements offer little protection from a tornado. While windowless rooms and closets offer more safety than other parts of the house, people are still left vulnerable to tragedy when storms strong enough to level entire structures come through. Storm shelters are built to withstand winds that standard household rooms are not equipped to handle. There have been cases of safe rooms remaining completely intact, protecting the people inside, as the entire building around it crumbles to the ground in a tornado. As people try to prepare for the worst, companies that produce do-it-yourself storm and tornado shelters are reporting a sharp increase in sales…”

NOAA Satellite Malfunctions; May Affect Forecasts. This is not a good development. Meteorologist Andrew Freedman at Climate Central has the story; here’s an excerpt: “As the weather system that spawned the deadly Moore tornado moves eastward, the main weather satellite used for observing and forecasting conditions across eastern North America and the Atlantic Ocean has gone offline. It’s the second malfunction since September 2012, when a technical glitch was fixed by engineers working from the ground. According to the National Oceanic and Atmospheric Administration (NOAA), which operates the nation’s fleet of weather satellites, the satellite, known as GOES-13, initially malfunctioned at 11:40 p.m. eastern time on Tuesday. An initial recovery procedure was unsuccessful at restoring it to operation…”

GOES-14 Starts Service As GOES-East. NOAA is using a spare satellite to try to make up for the GOES-13 outage; here’s an update from The University of Wisconsin CIMSS Satellite Blog: “At 1000 UTC (Thursday), GOES-14 imagery started flowing to AWIPS as the GOES-East satellite. Work continues on evaluating the status of GOES-13. GOES-14 remains at 105.5 West, and GVAR data are being broadcast directly from GOES-14. Updates on GOES-13 — and all satellites — can be found here.”

John McCain: Cable TV, The Right Way. The Television Consumer Freedom Act? Here is a clip of an Op-Ed from Senator John McCain at The Los Angeles Times that caught my eye: “…The numbers are striking. According to the Federal Communications Commission, the price for basic cable has grown by an average of 6.1% a year over the last 16 years — three times the rate of inflation and far outpacing the average American’s paycheck. Cable bills are projected to continue rising to an average of $200 a month by 2020. The 82% of American households that subscribe to cable or satellite television are stuck paying escalating prices for “bundled” packages of more than 100 channels, despite the fact that the average viewer tunes in to only about 18 of them. Reinforcing this fundamental unfairness is a federal regulatory and legal framework that tilts in favor of cable companies and television programmers at the expense of consumers…” (photo credit:

From Here You Can See Everything. Enjoy binge TV viewing? Hooked on Netflix? So am I. Maybe that’s not such a good thing, long term, as argued in this thought-provoking piece at; here’s an excerpt: “…I always binge on media when I’m in America. But this time it feels different. Media feels encroaching, circling, kind of predatory. It feels like it’s bingeing back. The basic currency of consumer media companies—Netflix, Hulu, YouTube, NBC, Fox News, Facebook, Pinterest, etc.—is hours of attention, our attention. They want our eyeballs focused on their content as often as possible and for as many hours as possible, mostly to sell bits of those hours to advertisers or to pitch our enjoyment to investors. And they’re getting better at it, this catch-the-eyeball game. Consider Netflix. These days, when one episode of The West Wing ends, with its irresistible moralistic tingle, I don’t even have to click a button to watch the next one. The freshly rolling credits migrate to the top-left corner of the browser tab, and below to the right a box with a new episode appears, queued up and just itching to be watched. Fifteen seconds later the new episode starts playing, before the credits on the current episode even finish. They rolled out this handy feature—they call it Post-Play—last August. Now all I have to do is nothing and moralistic tingle keeps coming….” (photo credit:

The Suicide Epidemic. I’ve lost too many friends and family members to suicide. As a society we don’t stigmatize people with diabetes, and yet another chemical imbalance, depression, is often brushed under the carpet. No, we can’t possibly admit to that, as if it’s a character flaw or genetic defect. But it’s not. Depression is treatable, with medication and therapy everyone can be helped. We have to keep pounding home that message, to our friends, colleagues and family members, and if you suspect someone is in a dark place, don’t ignore it – do something about it. Help them find the help they need. Read this article at The Daily Beast and then do something positive, like supporting SAVE (Suicide Awareness, Voices of Education), based in Bloomington with an international outreach. Their director (and a good friend of mine) Dr. Dan Reidenberg, has testified before Congress. SAVE has an amazing staff and volunteers working 24/7 to avoid senseless, horrific tragedies. Consider attending their annual Fashion Show to raise more funds to help more people in need – next Thursday, May 30, in Minneapolis. Details are here. I feel strongly about SAVE and it’s mission – I hope to see you there.

Climate Stories…

Floating Research Station In Need Of Evacuation. A friend forwarded me this article late last night – a Russian research facility near the North Pole being evacuated due to unstable ice. In May? More evidence of profound changes at the top of the world. Here’s an excerpt from The Barents Observer: “The scientific research station was placed on the ice floe in October 2012 and was planned to stay there until September. Now the floe has already started to break apart and the crew has to be evacuated as soon as possible. Russia’s Minister of Nature Resources and Ecology Sergey Donskoy has ordered that a plan for evacuation should be ready within three days, the Ministry’s web site reads. “A collapse of the station’s ice floe poses a threat to its continued work, the lives of the crew, the environment close to the Canadian Economic Zone and to equipment and supplies”, a note from the minister reads…”

The Odds Of Disaster: An Economist’s Warning On Global Warming. Here’s an excerpt of a Paul Solman interview with economist Martin Weitzman at The PBS NewsHour: “…Once it is in the atmosphere, CO2 remains there for a very long time. Even if CO2 emissions were cut to zero at some point in the future (a very drastic assumption), about 70 percent of CO2 concentrations over the pre-industrial level of 280 ppm would remain in the atmosphere for the following one hundred years, while about 40 percent would remain in the atmosphere for the following one thousand years. This, along with the possibility of bad outcomes, is the argument for keeping CO2 concentrations from reaching very high levels. Most people do not realize how difficult it is to stabilize CO2 concentrations. It is not nearly enough to stabilize CO2 emissions, which would cause CO2 concentrations to keep on increasing at the same rate as before. (This is because changes in concentrations are proportional to emissions.) The problem is that if you want to stabilize CO2 concentrations, you have to make drastic cuts in CO2 emissions. This is no easy feat. Yet, unless it is done, we are liable to reach very high levels of CO2 concentrations. Global warming skeptics would dispute or minimize the link between CO2 concentrations and temperature increases. Here is yet another uncertainty — are they or the mainstream climate scientists more right than wrong? But can we afford the luxury of assuming that a small minority of climate skeptics are more correct than the vast majority of mainstream climate scientists? What is the probability of that?…”

Has Global Warming Stalled? Noted climate scientist Kevin Trenberth has some answers in a post at The Royal Meteorological Society; here’s an excerpt: “Has global warming stalled? This question is increasingly being asked because of impressions about local weather being cool and wet, or because of impressions that the global mean temperature is not increasing at its earlier rate or the long-term rate expected from climate model projections. The answer depends a lot on what one means by “global warming”.  For some it is equated to the “global mean temperature”.  That quantity keeps going up but also has ups and downs from year to year.  More on that shortly. Why should it go up?  Well, because the planet is warming from human activities. With increasing carbon dioxide and other heat-trapping greenhouse gases in the atmosphere, there is an imbalance in energy flows in and out of the top-of-atmosphere: the greenhouse gases increasingly trap more radiation and hence create warming.   “Warming” really means heating, and so it can be manifested in many ways.  Rising surface temperatures are just one manifestation.  Melting Arctic sea ice is another.  So is melting of glaciers and other land ice that contribute to rising sea levels. Increasing the water cycle and invigorating storms is yet another.  However, most (over 90%) of the energy imbalance goes into the ocean, and several analyses have now shown this…”

Hot In My Backyard. This compilation of radio reports is worth a listen; here’s an overview of the series from This American Life: “After years of being stuck, the national conversation on climate change finally started to shift — just a little — last year, the hottest year on record in the U.S., with Hurricane Sandy flooding the New York subway, drought devastating Midwest farms, and California and Colorado on fire. Lots of people were wondering if global warming had finally arrived, here at home. This week, stories about this new reality….”

Heat-Related Deaths May Increase With Climate Change. Here’s an excerpt of a story from LiveScience and Fox News: “Heat-related deaths in New York City’s borough of Manhattan may rise about 20 percent over the next decade, according to a new study. Researchers at Columbia University in New York analyzed the relationship between daily temperatures and temperature-related deaths across all seasons between 1982 and 1999 in Manhattan, which comprises the most densely populated county in the United States. The findings were published online May 19 in the journal Nature Climate Change…”



Tornadoes And Climate Change: Huge Stakes, Huge Unknowns. In light of the Moore, Oklahoma tornado disaster people are asking “is there a link to a warmer, more energetic atmosphere?” Here’s an excerpt of a timely Jeff Masters post at Wunderblog: “… Is climate change already affecting these storms? These are hugely important questions, but ones we don’t have good answers for. Climate change is significantly impacting the environment that storms form in, giving them more moisture and energy to draw upon, and altering large-scale jet stream patterns. We should expect that this will potentially cause major changes in tornadoes and severe thunderstorms. Unfortunately, tornadoes and severe thunderstorms are the extreme weather phenomena we have the least understanding on with respect to climate change. We don’t have a good enough database to determine how tornadoes may have changed in recent decades, and our computer models are currently not able to tell us if tornadoes are more likely to increase or decrease in a future warmer climate…”

With damage estimated at $2.2 billion, the Tuscaloosa tornado was the 2nd most expensive tornado in world history, behind the 2011 Joplin, Missouri tornado. Fast forward to minute four to see the worst of the storm.” Source: Weather Underground.


Tornadoes And Global Warming: Is There A Connection? Here’s a good summary of the uncertainty involved in connecting the dots with climate change and tornadoes from National Geographic: “…Linking any particular weather event to climate change is always tricky, because weather is inherently random. But weather patterns can speak to a warming planet. Scientists can detect that extreme rain events, for instance, are already happening more often than they used to, and that a warmer atmosphere with more water vapor in it is making such events more likely. Tornadoes are different. Global warming may well end up making them more frequent or intense, as our intuition would tell us. But it might also actually suppress them—the science just isn’t clear yet. Neither is the historical record…”

Making Sense Of The Moore Tornado In A Climate Context. Climate Central meteorologist Andrew Freedman does a good job connecting the dots; here’s an excerpt: “…Tornado data does not reveal any clear trends in tornado occurrence or deaths that would suggest a clear tie to global warming, at least not yet. A recent paper published in the Bulletin of the American Meteorological Society found that the occurrence of EF-1 and stronger tornadoes on the Enhanced Fujita Scale has shown no trend since 1954, which was the first year of near real-time data collection. Instead, an increase in tornado counts of EF-0 or stronger tornadoes has been attributed to an uptick in observations of very weak tornadoes. The Enhanced Fujita Scale measures tornado strength based on the extent and type of damage that they cause (no surface weather station has ever survived a direct tornado strike to take wind measurements from inside a twister)…”

CBO: Carbon Tax An Option To Avoid “Catastrophic” Outcomes. Here’s an excerpt of a story at The Hill: “The Congressional Budget Office (CBO) noted Wednesday that a carbon tax could generate “significant” revenues for the United States and avert “catastrophic” effects of climate change. CBO said in a new report that there are many uncertainties about how to design and implement a carbon tax, but waiting too long to curb greenhouse gas emissions would have clear results. “[D]elays would increase the expected damage from climate change by increasing the risk of very costly, potentially even catastrophic, outcomes. … In general, the risk of costly damage is higher as the extent of warming increases and as the pace of warming picks up; thus, failing to limit emissions soon increases that risk,” the report said.…”


Seeking Clarity On Terrible Tornadoes In A Changing Climate. Here’s an excerpt of an Andy Revkin article at The New York Times: “The vulnerability is almost entirely the result of fast-paced, cost-cutting development patterns in tornado hot zones, and even if there were a greenhouse-tornado connection, actions that constrain greenhouse-gas emissions, while wise in the long run would not have a substantial influence on climate patterns because of intertia in the climate system. Some climate scientists see compelling arguments for accumulating heat and added water vapor fueling the kinds of turbulent storms that spawn tornadoes. But a half century of observations in the United States show no change in tornado frequency and a declining frequency of strong tornadoes…”

Why Rational People Buy Into Conspiracy Theories. I thought this was interesting – here’s a clip from a New York Times story: “…While psychologists can’t know exactly what goes on inside our heads, they have, through surveys and laboratory studies, come up with a set of traits that correlate well with conspiracy belief. In 2010, Swami and a co-author summarized this research in The Psychologist, a scientific journal. They found, perhaps surprisingly, that believers are more likely to be cynical about the world in general and politics in particular. Conspiracy theories also seem to be more compelling to those with low self-worth, especially with regard to their sense of agency in the world at large. Conspiracy theories appear to be a way of reacting to uncertainty and powerlessness…”

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 And if you’re on Twitter, you’ll find me @pdouglasweather
