November 21 in Minnesota Weather History:
1996:
Heavy snowfall accumulated over the same areas that were hit two days
earlier. Four to seven inches of snowfall were reported across the area.
Heavier snowfall occurred during the daylight hours of the 23rd.
Snowfall totals of six inches were reported in the Twin Cities,
Chanhassen, Stewart, St. James and Redwood Falls.
1970: Gale driven snow across Minnesota. 45 mph winds over Rochester and Duluth.
Winter Whispers
Life
is random; our future ultimately unknowable. Maybe that's why we take
some small comfort in the weather forecast. It's one of the few things
we can anticipate with any level of skill.
Perfect? Not by a long
shot. The 24-hour forecast accuracy, nationwide, is 88 percent. It's
human nature to remember the 12 percent of the time we blow it. Day 3-7
accuracy is improving about 1 percent every year, and new technology has
made "surprise" tornadoes, floods & blizzards more unlikely.
Predicting the future is hard. Ask any stock broker or economist. How's your fantasy football team doing? Welcome to my world.
NOAA
is predicting a slight cool bias for the Red River Valley into
February; no clear trend toward wetter or drier weather for the Upper
Midwest. The 90-day outlook is interesting to ponder, but confidence
levels are very low, especially this winter. I still think we'll wind up
slightly milder; an earlier spring in 2014 than we had this year.
Expect
colder than average temperatures into Thanksgiving week but no major
storms close to home. A soaking rain may slow things down out east
Tuesday & Wednesday; long-range guidance now hinting at a warming
trend by the first week of December.
Fresh Air.
ECMWF guidance suggests temperatures will struggle just to reach 20F in
the MSP metro area Saturday, a slow warming trend kicking in Sunday and
Monday before another cool-down by the middle of next week. No big
storms are brewing next week, a clipper-like system may spark a dusting
or coating of light snow next Thursday night. Graph: Weatherspark.
Ski Texas.
The 12km NAM model shows some (very) plowable amounts of snow over
northern Texas and southern Oklahoma. Skiers will be happy over southern
Colorado - lake effect snows piling up as deep as 4-8" into Sunday
night. Map: NOAA and Ham Weather.
Blue Norther.
That's what they call vigorous Canadian cold fronts racing across
Texas, capable of dropping temperatures 40F or more in the span of a few
hours, sometimes under blue skies. The 32F isotherm pushes as far south
as Mexico, helping to whip up significant snow and ice across Texas. A
frost/freeze is possible from Huntsville to Atlanta by Sunday morning.

Coldest Weather Into Early December: New England.
The winds aloft will be "modified Pacific" for much of the central and
western USA into the first week of December, the coldest winds of Canada
brushing New England over the next 1-2 weeks. Map: NOAA.
Extended Temperatures Outlook.
The map above shows NAEFS guidance between November 29 and December 5, a
chilly bias for much of the south and east, while temperatures begin to
moderate over the rest of the USA. Map: NOAA.
A Wintry Sting.
The coldest air of the winter season is draining south, sparking heavy
snow over the southern Plains by Sunday, a noticeable wind chill east of
the Rockies. In today's
Climate Matters we track the chill, define a "Blue Norther" and take a look at Thanksgiving weather for a few select cities across the USA: "
WeatherNationTV
Chief Meteorologist Paul Douglas shows the newly released NOAA Winter
outlook which gives 50/50 chances for much of the US. The Thanksgiving
forecast is looking a bit chilly, especially depending on where you
live. And Finally, just what is a Blue Norther? And why can it cause a
60° temp drop in a few hours?"
Winter Temperature Outlook. NOAA just released their
latest prediction
for December through February. Their Climate Prediction Center shows a
cool bias for the Dakotas and Red River Valley, considerably warmer than
average temperatures expected over the southern USA and portions of New
England, as well as western Alaska. Interesting fodder for casual
conversations about the weather, but (as always) don't bet the farm
based on (any) long range forecast.
NOAA's Winter Precipitation Outlook.
This is something of a head-scratcher, a slight dry bias for portions
of the Southwest and Southeast, wetter/snowier than average for the
northern Rockies, otherwise go ahead and flip a coin - most of America
forecast to see winter precipitation very close to average.

Super Bowl 2014 Forecast: 50 Years Of Weather Stats Hint At Mother Nature's Playbook.
Speaking of vague, nebulous long-range forecasts. When in doubt, which
is much of the time, come to think of it, go with the long-term weather
averages. Here's an excerpt of a good story about Super Bowl 2014
weather predictions for New Jersey from The Star Ledger at
nj.com: "
Throw
out the Farmer’s Almanac. The forecast for kickoff time at Super Bowl
XLVIII at MetLife Stadium: Partly cloudy with temperatures in the mid-
to upper-30s. Obviously, pinning down the exact forecast for the big
game three months out is impossible, but statistically, based on
historical records provided by the state’s climatologist, that is the
most likely scenario when the nation’s most prominent sporting event
comes to New Jersey. Could it be 65 degrees and clear? Sure. Could it be
20 with blizzard conditions? It’s not out of the question..."

Judah Cohen's Winter Outlook: A Downer For East Coast Winter Weather Lovers.
Cohen specializes in long range forecasting, and his recent track
record is impressive. He has perfected the art of linking snowcover in
Sibera with weather downwind over North America, but this year he sees
conflicting signals. Here's a clip from an interview conducted with
The Capital Weather Gang: "...
I
have to admit that I am struggling with how to interpret the
conflicting predictions based on Siberian snow cover. . . . Based on
what I have seen so far the hemispheric circulation of the atmosphere
has evolved more consistently as if the Siberian snow cover was below
normal or closer to the prediction derived from the SAI. Therefore, this
favors an overall positive winter AO. However I do see signs, based on
the large-scale energy propagation of the atmosphere, that favor
building of high pressure in the mid-high latitudes in the near term and
that should help to support colder temperatures and even a negative AO
right at the start of winter. Eventually I would expect atmospheric
conditions to favor a more positive AO but that is no guarantee..."

from much of the Midwest into the Southwest. Drought conditions are
forecast to develop over the Southeast, from Mobile to Atlanta,
Jacksonville and the Carolinas.

Losses From Extreme Weather Rise To $200 Billion A Year Over Past Decade.
Reuters has the story; here's an excerpt: "
Global
economic losses caused by extreme weather events have risen to nearly
$200 billion a year over the last decade and look set to increase
further as climate change worsens, a report by the World Bank showed on
Monday. A United Nations' panel of
scientists has warned that floods, droughts and storms are likely to
become more severe over the next century as greenhouse gas emissions
warm the world's climate. "Economic losses
are rising - from $50 billion each year in the 1980s to just under $200
billion each year in the last decade and about three quarters of those
losses are a result of extreme weather," said Rachel Kyte, World Bank

One, that the country is undergoing an unprecedented level of economic

Just 90 Companies Caused Two-Thirds Of Man-Made Global Warming Emissions. Details from
The Guardian: "
The
climate crisis of the 21st century has been caused largely by just 90
companies, which between them produced nearly two-thirds of the
greenhouse gas emissions generated since the dawning of the industrial
age, new research suggests. The companies range from investor-owned
firms – household names such as Chevron, Exxon and BP – to state-owned and government-run firms. The analysis, which was welcomed by the former vice-president Al Gore as a "crucial step forward" found that the vast majority of the firms were in the business of producing oil, gas or coal, found the analysis, which has been accepted for publication in the journal Climatic Change..."

Canadian
environmental scientist David Keith wants to change the world's climate
by creating a type of sun filter in the sky to halt global warming. In
an interview, he argues the technology is effective and inexpensive, but
critics liken it to a nuclear bomb. While delegates meeting in Warsaw

Globe's Unbroken Warm Streak Approaches 29 Years. Details from
Climate Central; here's the introduction to the article: "
The
globe’s unbroken hot streak is inching closer to 29 years, with new
data showing that October was the 344th consecutive month with global
average surface temperatures above the 20th century average. According
to data from the National Oceanic and Atmospheric Administration released
on Monday, the global average surface temperature for the month
of October was 1.13°F above the 20th century average (1961-1990) for the
month. That’s enough to make this the seventh-warmest October on record
in what is also likely to be the seventh-warmest year on record,
according to a recent report from the World Meteorological Organization.
The last time the globe had a cooler-than-average month was February
1985, and the last cooler-than-average October occurred in 1976, shortly
before Jimmy Carter beat Gerald Ford in that year's presidential
election..."

Africa, which is already highly vulnerable to climate variability.
Further volatility could be ruinous. Two-thirds of the continent is
desert or drylands, and three-quarters of its agricultural drylands are
significantly degraded. The Sahara Desert is expanding: Lake Chad, for
example, is now one-tenth of its size a half-century ago. The worst
conditions are in the Horn of Africa and the Sahel, where drought and
famine have left more than one million children at risk of severe
malnutrition. Africa emits a mere 4 percent of the world’s CO2, but it
suffers most from its ill effects. That said, Africans bear some of the
blame, too: for example, four million hectares of African forest
disappear annually – twice the global rate of deforestation..."
