36 F. average high on November 25.
24 F. high on November 25, 2014.
8.9 F. November in the Twin Cities is running nearly 9 degrees warmer than average, to date.
November 26, 2001:
A strong low pressure system develops in Colorado on the 25th, reached
eastern Iowa during the evening of the 26th, then moved into eastern
Wisconsin late on the 27th. It produced a wide swath of heavy snow
across much of central Minnesota into West Central Wisconsin. Storm
total snowfall of 8 inches or more was common, with a large area
exceeding 20 inches. Specifically, Willmar picked up 30.4 inches, New
London saw 28.5 inches, Collegeville had 23.4 inches, Litchfield and
Granite Falls received 22 inches, and Milan had 20 inches. A convective
snow band set up across this area on the 27th and remained nearly
stationary for over 12 hours, resulting in the extreme storm totals.
From 8 am on the 26th to 8 am on the 27th, Willmar received 21 of its
30.4 inches, setting a record for most snowfall in Willmar in a 24 hour
period. The heavy wet snow downed numerous power lines, and at one
point, at least 20,000 customers were without power in the
Minneapolis-St. Paul metropolitan area. Over one thousand traffic
accidents were noted across the entire area. Most were minor, but one
accident claimed two lives when a car spun out and collided with a semi
near Mora.
November 26, 1995:
A narrow band of five to eight inches of snow falls from west central
Minnesota around Canby and Granite Falls to east central Minnesota. This
included much of the Twin Cities metro area.
November 26, 1965: A snowstorm develops across northern Minnesota. 14.7 inches of snow fell at Duluth, along with 13.6 inches at Grand Rapids.
November 26, 1896:
A severe Thanksgiving day ice storm develops over southwest and central
Minnesota. 1.42 inches of freezing rain falls at Bird Island, and 1.20
inches of freezing rain falls at Montevideo. The ice causes a great deal
of damage to trees and shrubs. Source for historical weather data:

A Thanksgiving Brush With Slush; Sloppy Coating to 1" "If the only prayer you said in your whole life was "thank you" that would suffice" wrote Meister Eckhart.
My
wife and I just returned from the Middle East: Israel, the West Bank,
Jordan and Dubai, which is a blend of Las Vegas, New York and
Disneyworld. We saw Syrian refugee settlements in Amman, Jordan and
heard some heartbreaking stories. After a trip like that you return with
new eyes, and a heightened sense of gratitude.
In what may be an
omen of a "stunted winter" to come today's storm (it hardly fits the
definition) tracks south of MSP. A couple inches of slush may fall on
Mankato and Rochester, a coating to an inch for the metro, with most
roads staying wet. No. Big. Deal.
El Nino winters tend to be
milder, with a majority of the biggest storms tracking south of
Minnesota. We'll see snow and cold, but probably not in the volume we're
all accustomed to.
Expect dry roads and chilled sunshine
Friday and
Saturday; the next chance of light flurries late
Sunday. Long range models show a relatively mild, Pacific wind flow returning by mid-December.
The
WMO says 2011-2015 was the warmest 5 year period on record, worldwide.
Details below. A happy and safe Thanksgiving to you and yours.
Nuisance Snow.
Based on the latest guidance I'm thinking a coating to 1" in the metro
(best chance of an inch from Shakopee to Eagan, maybe a couple inches
from Northfield to Hastings. With daytime temperatures near freezing
major roads and freeways should be mostly-wet, but early morning and
evening conditions may be slippery, especially south and east of the
Twin Cities. Map source: Twin Cities National Weather Service.
Narrow Stripe of Accumulating Snow.
NAM guidance shows an inch or two of slushy snow from Fairmont and
Albert Lea to Owatonna and Red Wing, maybe as much as 3" of sloppy snow
in a few spots, the best chance of accumulating snow late afternoon and
evening as we lose daylight and meager radiational heating. Source: NOAA
and AerisWeather.
More Snow South of MSP.
Models print out just under an inch for Maple Grove and northern
suburbs, closer to 2" or more near Northfield, enough to temporarily
cover up those unnaturally green lawns. Graph: Aeris Enterprise.
Thanksgiving Slush.
Models show the best chance of 2-3" of snow from near Albert Lea to Red
Wing and Eau Claire; amounts dropping off rapidly as you head north and
west of the Twin Cities.
Risk of an Inch.
At the rate we're going an inch of slush may be a big deal, especially
at rush hour, especially with temperatures colder than 20F. Our internal
models suggest an inch of slush at MSP by 6 PM this evening. Source:
Aeris Enterprise Mobile.
Winter Weather Advisory.
Roads may be slushy and icy, especially south and east of Minneapolis
and St. Paul, with a mix of wet snow and freezing drizzle. Details from
the Twin Cities Weather Service:
A WINTER WEATHER ADVISORY HAS BEEN ISSUED FOR PARTS OF SOUTH
CENTRAL AND SOUTHEAST MINNESOTA...AS WELL AS WEST CENTRAL
WISCONSIN FROM 6 AM TO 9 PM THANKSGIVING DAY. THIS ADVISORY IS
MAINLY SOUTHEAST OF A LINE FROM FAIRMONT TO RED WIND
MINNESOTA...TO MENOMONIE AND LADYSMITH WISCONSIN. A MIXTURE OF
SLEET...FREEZING DRIZZLE OR FREEZING RAIN WILL DEVELOP THURSDAY
MORNING...BEFORE MIXING AND CHANGING OVER TO SNOW BY THE
AFTERNOON. THERE COULD BE A PERIOD OF MODERATE SNOWFALL DURING THE
AFTERNOON ONCE THE PRECIPITATION CHANGES OVER TO ALL SNOW. A QUICK
1 TO 3 INCHES WILL OCCUR IN THE ADVISORY AREA WITH A LIGHT COATING
OF ICE...BUT THIS SHOULD BE CONFINED TO ELEVATED OBJECTS...BRIDGES
AND OVERPASSES.
Zonal Flow Lingers into Mid-December.
Despite a cooling trend into the weekend and early next week the flow
aloft is predominately west to east, with very little cold air available
to tap across Canada into the second week of December. We may see a
series of nuisance snows, but no big dumpings are imminent.
One of the 3 Warmest Novembers in Recorded Minnesota History? That's according to climate guru Mark Seeley; here's an excerpt from this week's edition of
Minnesota WeatherTalk: "
Through
the first 25 days of November temperatures have been averaging well
above normal. It is likely that this month will conclude in a manner
that will rank it among the top three warmest Novembers in Minnesota
history, likely falling short of the warmest ever which occurred in
2001. Over 40 communities reported at least one day this month with an
afternoon temperature of 70°F or higher. In all 33 new daily maximum
temperature records were set within the National Weather Service
Cooperative Observer Network in Minnesota, and 145 daily warm minimum
temperature records were set, a remarkably large number. No low
temperature records were set anywhere in the state this month..."
Bizarre Thanksgiving Weekend: Ice Storm and a Hurricane. Here's an excerpt from
The Weather Channel that caught my eye: "...
There have been only three other eastern Pacific storms of record dating to 1949 that formed later in the season than Sandra did
on November 24. Sandra is the latest storm in the eastern Pacific since
Hurricane Winnie was a December oddball in 1983. El Niño seasons such
as the one we're currently in typically feature lower wind shear over
the eastern Pacific basin, which otherwise rips developing or active
tropical cyclones apart. Sandra formed in a relatively small window of
lower wind shear, and also capitalized on water temperatures from 1 to
1.5 degrees Celsius above average to fuel its convection..."

2015: Hottest Year Worldwide Since Records Started in 1880.
Unless another "polar vortex" sets up in the coming weeks (unlikely)
2015 will be even warmer than the previous record: 2014. 14 of the 15
warmest years, worldwide, have occurred since 2000. Here's an excerpt
from
US News: "...
Scientists
at the U.S. National Oceanic and Atmospheric Administration and
elsewhere already were saying that 2015 likely would be the hottest. The
U.N. agency, NOAA, NASA and Japan's weather agency all say 2014 is the
current record hot year with a global temperature of 14.57 degrees
Celsius, 58.23 degrees F. "I would call it certain," NOAA's chief
climate monitor, Deke Arndt, said on Tuesday. "Something game-changing
massive would have to happen for it not to be a record." Records go back
to 1880. Jarraud also said it is likely that the world has now warmed
by 1 degree Celsius, or 1.8 degrees Fahrenheit, over pre-industrial
times. That's a symbolic milestone: International leaders have set a
goal of keeping global warming within 2 degrees C, 3.6 F, of
pre-industrial times..."
World Meteorological Organization: 2015 Like to be Warmest on Record; 2011-2015 Warmest Five-Year Period. Here's an excerpt from a
WMO press release: "
The
global average surface temperature in 2015 is likely to be the warmest
on record and to reach the symbolic and significant milestone of 1°
Celsius above the pre-industrial era. This is due to a combination of a
strong El Niño and human-induced global warming, according to the World
Meteorological Organization (WMO). The years 2011-2015 have been the
warmest five-year period on record, with many extreme weather events -
especially heatwaves - influenced by climate change, according to a WMO five-year analysis..."
U.N. Study: Natural Disasters Caused 600,000 Deaths Over 20 Years. Three guesses which nation has experienced the most weather-related natural disasters? Here's an excerpt from
TIME: "...
The
extreme weather-related calamities also caused nearly $2 trillion in
economic losses. The figures were released ahead of a landmark climate
change conference set to take place in France. Roughly 335
weather-related catastrophes were recorded each year between 2005 and
2014, the report said. The five countries hit the hardest were the
United States, China, India, Philippines and Indonesia, according to the
report. The U.N. found that floods made up half of the recorded
disasters, resulting in 157,000 deaths. Storms killed 242,000 people,
mostly in poor countries, while heat waves accounted for 148,000 deaths..."

More Severe Storms Are Throwing Off Bird Migration.
Atlas Obscura has an interesting symptom of changing weather patterns; here's an excerpt: "
...If it wasn’t already enough to fly thousands of miles—44,000 round trip, if you’re the Arctic tern—birds
of all shapes, sizes, and flying styles are now facing increasing
obstacles to migration. Warmer weather is shepherding in shorter winters
and angrier storms, and there's recently been an upsurge in the
frequency and intensity of hurricanes. With shrinking winters affecting birds’ migration schedules, which start as early as June or as late as December, many birds find themselves awing during peak Atlantic hurricane season..."

New Urban Heat Island Study Shows Surprising Variations in Air Temperatures Across the Twin Cities.
Meteorologists have been tracking this effect for a long time, and in
certain cases it can make the difference between rain, slush or snow.

ScienceDaily: "...
Recording
surface air temperatures every 15 minutes from August 2011 through
August 2014 across nearly 2,000 square miles and using U.S. Geological
Survey data to fine-tune differences at the neighborhood level, the

Supercomputers, Tornadoes, and the Biggest Unsolved Mystery in Weather Technology?
Tornado warnings or "alerts" hours in advance? I wouldn't rule it out
in our lifetime, certainly our kid's lifetimes. Here's an excerpt of an
interesting article at
The Atlantic: "...
There
are some technologies that can help. A specific radar signature called a
“debris ball,” for example, suggests that there is debris in the air
from a tornado having wrecked something. Some researchers believe
improvements in radar could eventually mean reliable tornado warnings up to an hour
ahead of time. Vaccaro says he can imagine even longer lead-time, given
enough observational data and the processing power from supercomputers
to analyze it. Computers already process trillions of weather-related
data points per second, which is a large part of why long-term
forecasting accuracy, in general, is so much better today than it was
even a decade ago..."

10 Things Everyone Should Know About Seasonal Affective Disorder.
"SAD" is very real for many people; the dark days of winter can take a
mental and physical toll. Here's a snippet of a helpful article at
Huffington Post: "...
In
most cases, SAD is just a seasonal component of clinical depression or
bipolar disorder, according to Michelle Riba, a professor of psychiatry

Center. "For people who see a regular pattern every year of getting sad,
anxious or a cycling of moods, the first thing they need to do is to
see someone to get an overall diagnosis," she said. "They need to treat

A Car Dealers Won't Sell: It's Electric.
The reasons many car dealers aren't more enthusiastic? Hard to say, but
when in doubt follow the money. And yes, that's a RAM 1500 truck in my
garage (which I love). The day Dodge, Ford or Tesla makes an
all-electric pick-up truck with a 300-500 mile range I'll be one of the
first to put down a deposit. Here's an excerpt from an article at
The New York Times: "...
Industry
insiders and those who follow the business closely say that dealers may
also be worrying about their bottom lines. They assert that electric
vehicles do not offer dealers the same profits as gas-powered cars. They
take more time to sell because of the explaining required, which hurts
overall sales and commissions. Electric vehicles also may require less
maintenance, undermining the biggest source of dealer profits — their
service departments..."

Climate Stories...
Study Drives a Nail into the Global Warming "Pause" Myth. Here's the introduction to a recap at
The Guardian: "
Despite
the organization and funding behind groups which try to cast doubt
about the causes and implications of climate change, the facts have
spoken. The world continues to warm and their favorite myths have died.
We know that human-emitted heat-trapping gases warm the planet. In fact,
this has been known for well over a century. With modern instruments
(like ocean thermometers and satellites among others) we are now
measuring the change. With advanced climate models, we can predict the
changes. The measurements and the predictions are in excellent agreement, despite what cable news and second-rate skeptical scientists say..."

New Study Finds No "Substantive Evidence" of a Global Warming "Pause".
Chris Mooney reports on a new study that confirms there never was a
warming hiatus - the warming is uneven but NASA data confirms NOAA's
recent findings; here's an excerpt of his story at
The Washington Post: "
Even as Lamar Smith (R-Tx.), chairman of the House Committee on Science, Space, and Technology, continues to investigate a high profile study from federal scientists debunking the idea of a global warming slowdown or “pause,” a new study reaches
the same conclusion — in a different yet complementary way. “There
is no substantive evidence for a ‘pause’ or ‘hiatus’ in warming,” write Stephan
Lewandowsky, a professor at the University of Bristol in the UK, and
two colleagues in Tuesday’s Nature Scientific Reports. “We suggest that
the use of those terms is therefore inaccurate...”

Lamar Smith is Hot and Bothered about Climate Science.
US News
explains the probe of NOAA data and studies on the alleged "pause" and
how it's become just the latest political football in Washington D.C.
Here's an excerpt: "...
Some see a bit of a parallel between the
Soviet-style intimidation and a recent campaign in the House Science,
Space and Technology Committee, where Chairman Lamar Smith has pressed
forward with a probe questioning the processes and findings of a federal
scientific agency – one that has led critics to accuse the Texas
Republican of abusing his power and to warn of a chilling effect on
further scientific research. Smith has demanded via subpoena, public
pronouncements and heated letters that the National Oceanic and
Atmospheric Administration turn over internal emails on global warming
research. The Texas Republican also has sought to bring agency staffers
and NOAA Administrator Kathryn Sullivan into closed-door,
deposition-like interviews..."

The Growing Republican Rift over Climate Change.
As a moderate Republican (remember those?) science-denial makes me
crazy and prone to moments of despair, but I sense the ship is turning
on climate science, however slowly. Here's the intro to a story at
desmogblog: "
As the world gears up for the climate negotiations kicking off in Paris next week, Republicans in the United States are doing everything in their power
to make sure that no climate deal takes place without their approval
(which will never happen.) But there are a few Republicans in leadership
positions in Washington that have had enough of being labeled the
“anti-science” party, and they are hoping to turn the GOP
onto the idea that climate change is very real. Republican Senators
Kelly Ayotte, Lamar Alexander, Lindsey Graham, and Mark Kirk have created a new committee that will meet periodically to talk about environment and energy issues..."
Exxon Made Deep Cuts in Climate Research Budget in the 1980s. Following up their 6-part series,
InsideClimate News
has the latest installment on Exxon's climate science research and the
mixed messages they were sending at the time; here's an excerpt: "...
But
several documents uncovered by ICN show that the budget cuts during the
1980s were steep and sudden. The cuts reversed the course that the
company followed in the late 1970s, when top company scientists warned
Exxon's management for the first time of the risks of climate change,
and launched internal research programs unparalleled among its oil
industry peers. ICN provided an Exxon spokesman copies of the documents
being published today and requested any additional information about
climate research spending during the 1980s, the period closely examined
in ICN's series, "Exxon: The Road Not Taken." The spokesman, Alan Jeffers, declined to provide any additional budget numbers..."

Energy Companies Risk $2.2 Trillion as Climate Goals Cut Demand. Here's more perspective on carbon-related risk from
Bloomberg Business: "
Oil,
natural gas and coal producers are risking $2.2 trillion by investing
in projects for which there will be no demand if the world meets a
United Nations target of limiting the rise in temperature to less than 2
degrees Celsius, a non-profit think tank said. No new coal mines are
needed, oil demand will peak around 2020 and growth in gas will
disappoint industry expectations, Carbon Tracker Initiative said
Wednesday in a report. The U.S. has the greatest exposure with $412
billion of projects at risk up to 2025, followed by Canada with $220
billion, China $179 billion, Russia $147 billion and Australia $103
billion, according to the think tank..."
