Springlike Weekend in the East, Rare Heavy Snow in the Middle East

Ask Paul. Weather-related Q&A:

Paul, the weather guy,



I have seen in the news paper the degree heating and cooling days on a yearly basis.  Has anyone done a ten year moving average of the degree heating and cooling days?  This is a very common thing in the stock market to see how a stock is behaving over a particular period.  It would seem to provide a way to see long term changes in our climate.





I asked Pete Boulay, at the Minnesota Climatology Working Group, for his perspective and here is an excerpt of what he wrote:



We usually prefer a 7-year moving average to look at recent trends. Here is a graph of seasonal HDD (heating degree data) values for the Twin Cities from 1891-92 to 2011-12 (the last time we have a complete season). Yes, I believe we have saved a lot of money (heating our homes and businesses) in recent winters.”



Tracking The Trends. The graph above, from the Minnesota State Climatology Office and the MN DNR, shows heating degree days since 1891-92. To calculate the heating degree data for any given data determine the average temperature (high and low) and subtract from 65. So an average of 10 degrees F. would equate to 55 heating degree days, and then add them up over time. The black solid line above shows a smoothed trend line, showing a drop in HDD since the early 70s as Minnesota winters have warmed over time. It’s hardly breaking news: our winters are trending milder over time.

Hi Paul,



I live in Inver Grove Heights, MN and Robins are here already. This is the earliest I’ve seen them that I can recall. What is your take on this?


Best regards,



Jerry Wussow



Jerry – those are brave robins, that’s all I can say. By Saturday they will probably regret their decision to stay (or migrate) to Inver Grove Heights. I suspect it’s a fluke – I can’t say I see any sign (yet) of an early spring, nothing like what we experienced last “winter”. Thanks for passing this along.



Coldest Nighttime Lows at MSP Since 1963. Here is another interesting way to look at the data, a graph showing the coldest nighttime low (for every winter) going back nearly 60 years. The black line is the trend line over time, showing the same gradual warming trend. It’s not getting as cold, for as long, as it did back in the 60s and 70s. Again, if you’ve been paying attention, this hardly comes as breaking news. Thanks to Jack Falker, an accomplished rose grower from Edina, for passing this along. Jack has compelling evidence that the Twin Cities metro is already in USDA Zone #5 (warming from Zone #4 in recent years). He suspects we may be close to entering Climate Zone #6 before long. Jack Falker writes:

Twin Cities in USDA Zone 5


With our very warm 2012, and much warmer than normal winter-to-date in 2013, it becomes more and more obvious to me as a rose gardener that the Twin Cities have moved firmly into USDA Zone 5, where the extreme minimum temperature (EMT) is expected to be between -10 and -20 degrees, rather than our previous EMT expectation in Zone 4 of -20 to -30 degrees. 



Notice how the upward slope of the 50 year graph I developed using Minnesota Climatology (NOAA) statistics, takes us right out of USDA Zone 4 into Zone 5.  And following that upward slope, it looks like we could be headed higher yet toward Zone 6 (EMT -0 to -10).  Last fall and winter-to-date in 2013 certainly bear that out.  Our EMT thus far in January was -5 on January 1st  and, looking at the models in your weather blog on Thursday, January 10th, it looks like we might not get much colder than that, which would be our first zone 6 winter, with the highest EMT on my 50 year graph and perhaps in history.”




Global Weather Whiplash. Here’s the latest installment of my (daily) climate headlines, available at YouTube: “Unprecedented Heat in Australia, Snow in the Middle East. In today’s climate segment, Meteorologist Paul Douglas looks at some of the weather extremes around the world.”





84 Hour Snowfall Forecast. Here’s the latest NAM outlook, showing a couple inches from near Fargo/Moorhead into the Red River Valley, a major snowfall for the Dakotas, Wyoming and Montana.


NAEFS Extended Outlook. Experimental long-range guidance from NOAA’s NAEFS model keeps the worst of the cold wave near Hudson Bay between January 18-24. Confidence level: low.



Climate Headlines. Here’s one YouTube link that has all the 2:30 climate headlines I’m creating for WeatherNation TV and our other media partners – a chronological list of segments highlighting some of the biggest weather and climate stories that made me do a double-take.

January Golf? My father lives in Lancaster county, Pennsylvania, about 80-90 minutes west of Philadelphia. With unseasonable warmth in the forecast the local golf course has decided to open up next weekend. No tee times are required. Sounds like a good plan to me.

Grandparents Save Five Kids From “Tornadoes Of Fire” in Australia. I’ve never ever seen anything quite like this – an excerpt of a harrowing, life and death story at Get Energy Smart Now! “Breathtaking images: “Grandfather Tim Holmes took these harrowing photos of his five grandkids escaping the wildfires because he feared their parents ‘would never see them again.’…..Mr Holmes told how he sent his wife, their grandchildren and pet dog Polly to the nearby sea jetty when he saw smoke from the looming wildfire rise from a nearby ridge.’For the next two-and-a-half hours, we huddled under the jetty as the fire intensified and produced a plume of smoke, ash and debris that left us with very little oxygen…”

Australia Braces For More Blistering Heat After Record Bursting Spell. Meteorologist Jason Samenow has more details at The Washington Post’s always-informative Capital Weather Gang; here’s an excerpt: “Four of Australia’s hottest 10 days on record have occurred this young calendar year and another punishing round of heat is on the way. On Monday, Australia’s average high temperature reached a scorching 40.33 C or 104.5 F, the hottest day on record. David Jones, manager of climate monitoring for Australia’s Bureau of Meteorology told the Associated Press that the extent, duration and intensity of this summer’s heat wave is “arguably the most significant in Australia’s history.”

Too Hot: Australia’s Big Heat-Breaking Records. Here’s an excerpt of a story on the historic levels of heat gripping Australia from New Zealand’s Hot Topic: “…NASA’s Earth Observatory provides this overview of the fires in Tasmania over the weekend that caused chaos and destruction in the normally cool state — Hobart hit an all time high temperature of 41.8ºC, a full degree above its previous record. Fire danger in parts of New South Wales has been classified as catastrophic, and this NASA Worldview image for Jan 8th appears to show smoke from fires in southern NSW streaming out to the east and over the sea towards New Zealand…”

Deadly Storms Blanket Parts of Mideast In Snow. The BBC reports; here’s an excerpt: “The worst storms to hit the Middle East in a decade have claimed several lives and left large parts of Israel and Jordan blanketed in snow. Across the region, many schools are shut and thousands of homes are without power. Heavy snow in Jerusalem on Thursday brought transport to a standstill. The freezing conditions have brought misery for thousands of Syrians living in refugee camps in northern Jordan, Turkey and Lebanon. Two weather-related deaths were reported in Lebanon including that of a baby swept away in a flash flood...” (Photo credit: Reuters).

9 Worst Things About Being Over 50? Yes, I can relate. In my head I’m still 24. My body, however, disagrees (loudly) some mornings. Here’s an excerpt of an article at PBS’s Next Avenue that caught my eye: “On the upside, growing older means you’ve accumulated a good deal of experience and wisdom as well as an abundance of instructive and entertaining stories. But there’s a sharp downside, too. Take action now to make sure that the challenges below don’t end up defining your second and third acts.

1. You’re closer to the end. Planning for the end of life — your own and that of your elder loved ones — is more urgent than ever before. Not doing so may mean enduring costly medical measures that prolong life without sustaining its quality and burdening others with agonizing decisions based on guesswork.

Solution: Have end-of-life conversations with family members soon, fill out the legal documents that make your medical wishes and estate management affairs clear and analyze long-term care insurance options.…”

3-D HDTV – Without The Glasses? This article at caught my eye; here’s an excerpt: “In addition to a 110″ Ultra-HD LED TV, Hisense also revealed its latest take on glasses-free 3D technology at CES with the GF60XT980 television concept. The new 60-inch TV uses an Ultra High Definition (UHD) panel to provide a clear, 3D picture from almost any angle, so multiple viewers can enjoy the 3D effect without needing multiple pairs of glasses...”

Old Fashioned “Windshield Wiper”. Not sure where this is from, but I’m feeling better about the wipers on my car.


January Broomball – In The Rain? Thanks to meteorologist Todd Nelson, who shared this photo last night. Todd can’t remember a time he was broomballing in the rain. Odd.

Climate Stories…

“There are two ways to be fooled. One is to believe what isn’t true; the other is to refuse to believe what is true”.

– Soren Kierkegaard (1813-1855)

Climate Change In The Age Of Truthiness. Here’s a clip of an article at The Energy Collective that resonated with me. Lately it seems truth (at least about climate change and the scientific method) has entered a slippery slope: “Does reality shape our beliefs, or do our beliefs shape “reality”? A fascinating paper by “Did the Arctic Ice Recover? Demographics of True and False Climate Facts” by Lawrence Hamilton examined this question using polling data on people’s beliefs about climate change and their knowledge of several key climate facts, including that the Arctic sea ice is decreasing. Hamilton finds that existing beliefs about climate change influence acceptance of the facts, or, better put, which “facts” one chooses to accept. In the study, 80% of people who believe climate change is happening and is caused by human activity know that sea ice is declining. Of those who do not believe climate change is happening or who do not think it is caused by human activity, however, only 60% think the Arctic sea ice has been in decline…”

Has Global Warming Ground To A Halt? The short answer is no, but there are a lot of persistent denialists out there who would have you believe otherwise. Details in this excerpt from NewScientist: “The UK’s Met Office has downgraded its forecast for warming at the Earth’s surface over the next five years. Headlines this week announced that global warming is “at a standstill”. Climate sceptics crowed. But the Met Office said the outlook for later in the century remains unchanged. New Scientist looks at the facts.

Has global warming stopped, or hasn’t it?

Atmospheric warming has certainly slowed greatly in the past decade. The Met Office says this appears to be due to natural cycles that are counteracting the warming effect of greenhouse gases. After incorporating new analysis of natural cycles into its latest model of atmospheric and ocean circulation,
it has concluded that we are in for a few more years of little change. Having calculated annual global temperatures for the next five years, its best guess is that they will be, on average, 0.43 °C higher than the average for 1970 to 2000. That’s down from its previous prediction of a 0.54 °C rise. If the new prediction proves right, then 2017 will barely be warmer than most years in the past decade…”


16 (More) Years Of Global Warming. One of the denialist memes going around now is “there hasn’t been any warming since 1998.” Really? The last 9 consecutive 12 month periods over the USA “conus” have been the warmest ever observed. We’ve gone 28 years in a row with global temperatures consistently warmer than the 20th century average. If you strip away volcanic and solar activity, as well as biases brought on by El Nino and El Nina, there is no scientific evidence that the rate of global warming has slowed…or peaked…or dropped. None. Skeptical Science takes a look at the latest scientific conspiracy theory: “Human greenhouse gas emissions have continued to warm the planet over the past 16 years. However, a persistent myth has emerged in the mainstream media challenging this.  Denial of this fact may have been the favorite climate contrarian myth of 2012, first invented by David Rose at The Mail on Sunday with an assist from Georgia Tech’s Judith Curry, both of whom later doubled-down on the myth after we debunkedit.  Despite these repeated debunkings, the myth spread throughout the media in various opinioneditorials and stunts throughout 2012. The latest incarnations include this article at the Daily Mail, and a misleadingly headlined piece at the Telegraph. As a simple illustration of where the myth goes wrong, the following video clarifies how the interplay of natural and human factors have affected the short-term temperature trends, and demonstrates that underneath the short-term noise, the long-term human-caused global warming trend remains as strong as ever…”

What Nightly News Shows Can Learn From PBS’s Climate Coverage. Here’s an excerpt of a report from Media Matters: “A Media Matters analysis found that the nightly news programs on ABC, CBS and NBC largely ignored climate change in 2012, despite record-breaking temperatures and a series of extremeweatherevents in the U.S. By contrast, PBS NewsHour devoted almost twice as many segments to climate change as the other networks combined. When the National Climatic Data Center announced Tuesday that 2012 was the hottest year in recorded history for the contiguous U.S., broadcast networks admirably devotedsegmentsconnecting the announcement to climate change. But for most of the year they turned a blind eye to climate change, even while reporting on its consequences. Together, the nightly news programs on ABC, CBS and NBC devoted only 12 segments to climate change in 2012. PBS’ coverage stood out, with its nightly news program dedicating 23 segments to the issue…”

NASA Chases Climate Change Clues Into The Stratosphere. Here’s a clip from a recent article from NASA: “Starting this month, NASA will send a remotely piloted research aircraft as high as 65,000 feet over the tropical Pacific Ocean to probe unexplored regions of the upper atmosphere for answers to how a warming climate is changing Earth. The first flights of the Airborne Tropical Tropopause Experiment (ATTREX), a multi-year airborne science campaign with a heavily instrumented Global Hawk aircraft, will take off from and be operated by NASA’s Dryden Flight Research Center at Edwards Air Force Base in California. The Global Hawk is able to make 30-hour flights. Water vapor and ozone in the stratosphere can have a large impact on Earth’s climate. The processes that drive the rise and fall of these compounds, especially water vapor, are not well understood. This limits scientists’ ability to predict how these changes will influence global climate in the future. ATTREX will study moisture and chemical composition in the upper regions of the troposphere, the lowest layer of Earth’s atmosphere. The tropopause layer between the troposphere and stratosphere, 8 miles to 11 miles above Earth’s surface, is the point where water vapor, ozone and other gases enter the stratosphere….”

The Market And Mother Nature. Here’s the intro to an Op-Ed in the New York Times from St. Louis Park’s Thomas Friedman: “Whenever I hear the word “cliff,” I am reminded of something that President Obama’s science adviser, John Holdren, used to say about how we need to respond to climate change because no one can predict when it might take a disruptive, nonlinear turn. “We are driving toward a cliff in a fog,” said Holdren about the climate, and that’s always a good time “to start tapping on the brakes.” Indeed, when you think about how much financial debt we’ve built up in the market and how much carbon debt we’ve built up in the atmosphere, the wisest thing we could do as a country today is to start tapping on the brakes by both emitting less carbon to bend the emissions curve down and racking up less debt to bend our debt-to-G.D.P. curve down. Unfortunately, we are still doing neither...” (satellite image above: NASA).

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
