Tracking "Bubba"
This naming of winter storms has gotten out of hand.
Nemo.
A creative product placement from Disney? There's a reason why NOAA
names hurricanes: when there are multiple storms in play assigning a
name cuts down on public confusion.Today's storm reminds me a little of a
college buddy: since this system is also big, slow, sloppy -
approaching from the south - let's call it "Bubba".
I promise not to make this a habit, but we can do better than Nemo.
A surge of warm air aloft will spark a little
freezing rain this morning (glaze ice possible, especially outside the
metro). A burst of wet snow may spark 2-4 inches of metro slush, but dry
air sweeping in by evening should cause any mix to taper. Deeper into
the cold air a foot of snow may fall from Pierre to Moorhead, maybe 6"
at St. Cloud.
Travel during this almost March-like storm gets
worse the farther north/west you drive away from the metro area today -
blowing and drifting an issue over western Minnesota by tonight. Skies
clear by late Monday; a quiet week on tap. Another clipper pulls more
frosty air arrives by late week, but not nearly as cold as a few weeks
ago.
The maps look chilly - no early spring this year.

showing a sloppy storm centered near Omaha, tracking northeast.
Predicted Snowfall: NAM. Expect a sharp gradient
across the metro, maybe an inch southern suburbs, to 3" far northern and
western suburbs. The St. Cloud area may pick up 4-6" with some 10-12"
amounts closer to Detroit Lakes and Moorhead. Well over a foot of snow
may pile up over the eastern Dakotas.
Predicted Snowfall: RPM. WSI's 12 km. RPM model
shows only 2" of snow for much of the metro (which I tend to agree
with), some 5-6" amounts near St. Cloud, maybe 8" for Duluth and 16"
over west central Minnesota, near Breckenridge and Wheaton. The farther
north/west you drive up I-94 or I-35 today the worse travel conditions
will become.
Winter Storm Warning. I expect a mish-mash of ice,
rain and snow in the metro today, possibly a burst of 2" of slushy snow,
maybe 3" far northern and western suburbs. By the time it's cold enough
aloft for all-snow a surge of dry air aloft (the dreaded "dry tongue")
will cause precipitation to taper off. Map above courtesy of NOAA. For

On The Edge. Deep into the cold air, where
precipitation will fall as all snow, over a foot of accumulation is
likely across much of the Dakotas, maybe 5-10" for far western
Minnesota, whipped up by 30-40 mph winds, creating white-out conditions
by tonight. Map: NOAA.
31.9" snow at Portland, Maine. This breaks the old
record of 27.1" set on January 17-18, 1979. This makes it the greatest
snowstorm on record at Portland, Maine. Source: Gray, Maine office of
the National Weather Service.

My Car's In There Somewhere. Seeing is believing; over 25" of snow in Boston. This photo was taken in South Boston by @Casieg.
Blizzard Paralyzes Connecticut. The Associated Press has an eye-opening
YouTube clip showing what happens when you mix 24-36" and 55 mph winds. Serious drifts.
Thunder-Snow? When the air is rising violently, in a
thunderstorm (or a blizzard) it's possible to get lightning and
thunder. In winter it means snow is usually falling at the rate of
2-4"/hour. Such was the case Friday night in Middle Island, New York,

YouTube and Christine Heeren.
Snowbound. Stephanie from Hyannis, Massachusetts
shared this photo of a small tree down on their minivan, after 18-24"
snow and 60 mph. wind gusts. She explained that her family had to crawl
out of a window to get outside - there was too much snow blocking the
front door!
Mixed Bag. At times today's weather may look like
something out of early March, with wet snow spiked with rain, even sleet
(ice pellets). A period of light rain may freeze on cold surfaces this
morning (freezing rain). The predicted sounding for 9 am (above) shows
temperatures above 32 F. about 2,000 to 3,000 feet above the ground. A
change back to wet snow is likely later today.
Climate Stories...
Climate Change And The Blizzard: Nor'easters More Fierce With Global Warming, Scientists Say.
Did warmer sea surface temperatures (and thus the availability of more
water vapor) turbocharge the blizzard? Professional climate science
deniers scoff at the idea, but there's sound science to back up the
claim. Here's an excerpt from
Huffington Post: "
Climate change may or may not have helped generate the nor'easter lashing the East Coast
this weekend. Such storms happen with some regularity, after all. But
the amount of snow the storm called "Nemo" ultimately dumps, and the
extent of flood damage it leaves in its wake, may well have ties to
global warming, climate scientists suggested. Michael Mann,
a climatologist who directs the Earth System Science Center at
Pennsylvania State University, compared a major storm like Nemo -- or
Hurricane Irene or Superstorm Sandy,
for that matter -- to a basketball slam-dunk with a lower net. "If you
take the basketball court and raise it a foot, you're going to see more
slam-dunks," Mann said. "Not every dunk is due to raising the floor,
but you'll start seeing them happen more often then they ought to..."
Climate Change Is Serving Up Doses Of Extreme Weather. Even In Winter.
It's basic physics: warmer air holds more water vapor, more potential
fuel for major rainstorms (and snowstorms). If we reach the point where
it's too warm for midwinter snows from Minnesota to New England it's
game over; we're truly living on a different planet, and no amount of
technology, clean energy or political decrees will help. We're not there
yet. Here's another perspective from
The Daily Climate: "
As
the Northeast digs out from under a mammoth blizzard, it might seem
easy for climate change skeptics to point to such intense storms as
evidence that global warming isn't real. They would be wrong. "Climate
change contrarians and deniers love to cherry-pick individual events to
argue that they are somehow inconsistent with global warming, when
they are not," said Michael Mann, director of the Earth System Science
Center at Pennsylvania State University. "As long as it's cold enough
to snow – which it will be in the winter – you potentially will get
greater snowfalls...."

Study: Global Warming Causes Most Monthly Heat Records Today. Here's a clip from a story at
Think Progress and Skeptical Science: "
A new paper published in Climatic Change
by Coumou, Robinson, and Rahmstorf (CRR13) examines the increased
frequency of record-breaking monthly temperature records over the past
130 years, finding that these records are now five times more likely to
occur due to global warming, with much more to come“..worldwide, the
number of local record-breaking monthly temperature extremes is now on
average five times larger than expected in a climate with no
long-term warming. This implies that on average there is an 80% chance
that a new monthly heat record is due to climatic change … Under a
medium global warming scenario, by the 2040s we predict the number of
monthly heat records globally to be more than 12 times as high as in a
climate with no long-term warming...”

increase in the number of heat records compared to those expected in a
world without global warming) for monthly heat records as it changes
over time (thin red line is annual data, thick red line smoothed with
half-width 5 years). This is compared with predictions from a simple
stochastic model based only on the global mean temperature evolution
(blue line with uncertainty band directly comparable to the smoothed
red curve)"
Global Warming Brings Severe Rainstorms. No, when it does rain, it's not falling as gently as it did for our grandparents. Here's an excerpt from
tgdaily.com: "
Extreme
rainfall events are becoming more and more commmon across the globe as
climate change brings higher temperatures, researchers say. The
University of Adelaide team looked at extreme rainfall and atmospheric
temperatures at more than 8,000 weather gauging stations around the
world between 1900 and 2009. "The results are that rainfall extremes are
increasing on average globally. They show that there is a seven
percent increase in extreme rainfall intensity for every degree
increase in global atmospheric temperature," says Dr Seth Westra.
"Assuming an increase in global average temperature by three to five
degrees Celsius by the end of the 21st century, this could mean very
substantial increases in rainfall intensity as a result of climate
change..."

The movie
comes out next month (no, Al Gore has nothing to do with this one). The
thrust of the movie: the Koch brothers and other key fossil fuel
companies have trillions of dollars on the line - so there is incentive
to push back on climate science, and do (or say) anything to create
doubt and confusion about what's really going on. I'm keeping an open
mind - but right now it appears that the uptick in severe storms, more
persistent droughts and rising sea levels is probably a symptom of
greenhouse gas levels approaching 400 ppm (parts per million) in the
atmosphere, a byproduct of burning fossil fuels. A natural cycle? Over
the eons greenhouse levels have fluctuated between 180 and 280 ppm. No.
This is not a natural cycle.
Climate Change Means More Fires, Insects In Forests, USDA Warns. Here's a clip from
registerguard.com: "
Big
changes are in store for the nation’s forests as global climate change
increases wildfires and insect infestations, and generates more
frequent floods and droughts, the U.S. Department of Agriculture warns
in a report released Tuesday. The compilation of more than 1,000
scientific studies is part of the National Climate Assessment and will
serve as a roadmap for managing national forests across the country in
coming years. It says the area burned by wildfires is expected to at
least double over the next 25 years, and insect infestations often will
affect more land per year than fires..." (file photo courtesy of the Grand Junction, CO office of the National Weather Service).
