Weekend Thaw - "Post Traumatic Weather Disorder"Relatives
out east are frantic. "Are we going to get another Snowzilla?" After a
2-3 foot blizzard they're all paranoid. And just because you're paranoid
doesn't mean they're not out to get you.
Back in 1998 my wife and
kids were driving to the dentist, when they got caught in a massive
hailstorm. My wife handled it well, gripping the steering wheel, yelling
"We're going to die!" For months after that scare my boys would call me
every day. "Is there going to be severe weather? Is it going to be bad?
Do we have to drive with mom?"
Anyone who's been through a flood,
blizzard, tornado or hurricane describes an almost PTSD-like trauma,
complete with anxiety, depression and sleepless nights. You never watch a
weather report quite the same way. Suddenly it's personal.
Then
again most TV meteorologists were traumatized by the weather at a tender
age, incentive to learn more about meteorology and try to reconcile
what happened to them. For me it was a tropical storm (Agnes, in 1972).
Who knows how many careers exceptionally bad weather has launched.
A welcome weekend thaw gives way to a couple inches of new powder
Sunday night and
Monday as much colder air drills southward. Blowing and drifting could make for rough travel outside the metro by early
Monday. Expect 1 or 2 subzero nights next week, but temperatures blip back up to average by next week.
Oh, how I long for "average weather".
Blizzard Watch Western Minnesota on Sunday.
The combination of a couple inches of new snow, plus strong winds
whipping up snow already on the ground may exceed blizzard criteria,
especially late afternoon Sunday into Sunday night, when winds could
exceed 50 mph.
Super-Sized Sunday Clipper.
NAM guidance still shows a couple inches of snow Sunday PM into Monday
AM; more over the Red River Valley and far western Minnesota, where this
could be a plowable snow event. The bigger concern is high winds
whipping up snow already on the ground, creating a potential for
blizzard conditions, especially Sunday night. 84-hour accumulated
snowfall: NOAA and AerisWeather.
Winds Peak Monday Morning.
Models still show sustained winds of 25-30 mph with higher gusts, which
will be more of a factor in open areas outside the metro area. Winds
ease by the middle of next week as colder air settles in. Graphic: Aeris
Enterprise.
Minor Canadian Occupation.
As is (always) the case the cold air comes in waves, like slowly
cresting swells on the beach. This beach faces due north, and the waves
of numbing air will be a poignant reminder that a low sun angle coupled
with long, snow-covered nights across Canada is still brewing up chilly
air. A couple inches of snow Sunday night heralds the arrival of cold
front #1; a colder cold front sparks a smear of snow Friday, coupled by a
better chance of negative numbers next weekend. Enjoy the thaw!
Colder Next Week - Nothing Too Forbidding.
It won't be as cold as 3 weeks ago, but temperatures may hold in single
digits and low teens by the middle of next week with a subzero wind
chill at times, one or two nights below zero next weekend, followed by a
slight rebound next week.
Moderately Cold.
This is a shift from previous trends in the 2-week GFS predicted winds
at 500 mb, suggesting a lingering Canadian flows for the northern tier
states, milder Pacific winds pushed south of Minnesota. We'll see if
this is a fluke or a real trend, but if this verifies we won't see any
extended thaws anytime soon.
Drought Update.
Mark Seeley takes a wider look at El Nino and the status of (historic)
drought in the western USA in this week's installment of
Minnesota WeatherTalk; here's an excerpt: "...
From
Brad Rippey at the USDA in his weekly USA drought briefing: Since
mid-October 2015, stormy weather in many parts of the country in part
driven by a strong El Niño has significantly reduced U.S. drought
coverage from 34.78 to 15.48%a drop of 19.30 percentage points. Where
drought remains, mostly in the Far West, there has been incremental
improvement. Although long-term concerns still include below-average
reservoir storage, groundwater shortages, and tree mortality, winter
precipitation has boosted spring and summer runoff prospects; improved
rangeland and pasture conditions; cut irrigation demands; and reduced
the need for supplemental feeding of livestock. California’s intrastate
reservoirs held just 54% of their normal water volume on December 31,
and that number may not appreciably improve until high-elevation snow
begins to melt in the spring..." (Graphic credit:

A Healthy Snowfall Offers Variety of Environmental Benefits. Today's weather blurb was, in part, inspired by a 2011 post at
The University of Delaware that reminded me of the many advantages of a significant snowfall: "...
This
blanket effect makes snow an excellent insulator for gardens and
landscapes, protecting these natural areas and their animal inhabitants
against frigid temperatures and damaging winds. Snow also lessens -- to
some extent -- the extremes of temperature fluctuation to which the soil
is subjected, says Hansen. This can be critical for some plants,
including evergreens. Even in mid-winter, if air temperature within the
canopy of these plants rises during the day, the plants will try to take
moisture from the soil. If the soil is frozen, the plants can actually
die of thirst. The extent to which snow insulates depends on its depth.
Generally, temperatures underneath a layer of snow increase about 2
degrees Fahrenheit for each inch of accumulation..."
January Hits New Record Low in Arctic. Here's an excerpt from
The National Snow and Ice Data Center: "
Arctic
sea ice extent during January averaged 13.53 million square kilometers
(5.2 million square miles), which is 1.04 million square kilometers
(402,000 square miles) below the 1981 to 2010 average. This was the
lowest January extent in the satellite record, 90,000 square kilometers
(35,000 million square miles) below the previous record January low that
occurred in 2011. This was largely driven by unusually low ice coverage
in the Barents Sea, Kara Sea, and the East Greenland Sea on the
Atlantic side, and below average conditions in the Bering Sea and Sea of
Okhotsk..."

The Southwest May Have Entered a "Drier Climate State". Here's an excerpt from
Climate Central: "...
We see a very intense trend in the Southwest,” Andreas Prein, a postdoctoral researcher at the National Center for Atmospheric Research, said. “
The Southwest might already have drifted into a drier climate state.” Prein, who led the research published on Thursday in Geophysical Research Letters,
looked at weather patterns rather than average trends in precipitation.
The team identified 12 major patterns, only three of which are
favorable for rain in the Southwest. In
an ominous finding for the region, they found that over the past 30
years, those three rainy patterns are becoming less frequent and the
rains and mountain snow that come with them are drying up..."

GOES-R: A Weather Superhero With Lightning Vision.
I am really looking forward to GOES-R going online with up to 1 minute
satellite updates and a real-time lightning mapper; here's a preview of
capabilities from
Lockheed Martin: "
Sure
it's bright, loud and sometimes scary, but if you watch lightning from
space, you can learn a lot about storms. The GOES-R satellite has a new
instrument called the Geostationary Lightning Mapper that can take
hundreds of images every second of all types of lightning. Think of it
as a weather superhero with 'lightning vision.' When it sees an increase
of lightning flashes, it can help weather forecasters predict a severe
storm or tornado, and give us more warning to go to a safe place."

Car Fumes Are Killing Us. So Why Isn't Anyone Telling Us Not To Drive? This study focuses on the UK, but the results and implications are more sweeping; here's an excerpt at
The Guardian: "...
Because air pollution – in the memorable phrase of Prof Chris Griffiths, who shared the preliminary findings of a study with Channel 4’s The Great Car Con last week – causes children growing up in polluted areas (of which my London borough is one) to develop “smaller, stunted lungs”. It also causes people to die from heart attacks, strokes and lung cancer, and exacerbates other lung diseases and asthma. Usually it’s not the only cause, but air pollution is a factor in at least 30,000 deaths each year in the UK, although scientists are struggling to disentangle the damage
caused by nitrogen dioxide from that caused by particulates, or soot.
By way of comparison, in the UK there are up to 100,000 smoking-related
deaths each year, nearly 9,000 alcohol-related ones and about 1,800
people killed in car crashes..."
Koch Network Frustrated by Trump. Here's an excerpt from

like a liberal. Of Bernie Sanders' crusade against the power of
corporations, he said, “a lot of what he says is true. The
businesspeople who are successful haven’t become successful because they
helped others improve their lives. It's because they helped rig the

practical things all the way to the real, extreme, worst-case
scenarios,” Bedford says. “The stuff that isn’t even that unthinkable
anymore.” Stuff like a massive electromagnetic pulse. Or an earthquake,
or a tidal wave, or a complete unraveling of the fabric of society —
stuff that would make for a second Great Depression. Not the end of the

Will
you ever be happy? The answer, it seems, is yes. Likely when you’re a

Climate Stories...
Climate Change Implicated in a Specific Extreme Weather Event. Severe
weather attribution is emerging science, but the link between warmer
air/oceans and an increase in flooding events is increasing. Here's an
excerpt from
National Geographic: "...
In an article
published in Nature Climate Change, the team said that their climate
model simulations showed that anthropogenic warming not only increased
the amount of moisture the atmosphere can hold but also caused a small
but significant increase in the number of January days with westerly
flow, both of which increased extreme precipitation. The authors
explained that climate change “amplified” the violent storms that led to the area’s wettest January in more than a century and that it has likely increased
the number of properties at risk and raised the costs of a flooding
event. Based on more than 130,000 simulations of what the weather would
have been like with and without human influence on the climate, the
study finds that man-made greenhouse gas emissions have raised the
possibility of extreme flooding by 43 percent..."
Did ExxonMobile Lie to Investors About Climate Change? Here's an excerpt from an article at
The Nation: "...
Telling
the truth is not only crucial; it’s the law. American firms must
regularly disclose to investors and the public all material risks that
could affect corporate operations and profitability. That will be a
challenging if not self-defeating exercise for fossil-fuel companies in
the post-Paris era. Telling the truth about Paris only figures to
further spook already-nervous investors. “There’s now a very clear
message that fossil-fuel use must be quickly and dramatically reduced,”
said an official involved with Schneiderman’s investigation. “Companies
must acknowledge that. If they disagree, they need to state why and
explain in clear, practical terms what the implementation of the Paris
Agreement means for their business and its future...”

actually do anything. It's a "sense of the Senate," which means the
amendment just serves to express an opinion to get Congress on record as
supporting or opposing an issue. The amendment calls out the tobacco,

tweaked. Even as the weather outside goes haywire, plants farmed indoors
can live out an optimized version of the weather that they coevolved
with — the weather of the past. The best weather of the past. Or, as
