In Like a Yak?
"If March comes in like a lamb it will go out as a lion?" How predictably pedestrian.
Sadly,
lions are endangered and lambs have hired lawyers. I was raised (by
wolves) to believe that, when March comes in like a yak, it will go out
like an emu. Or is it tortoise and aardvark? I'm just not good with
animals.
I apologize for any confusion.
Welcome to March, a
baffling month of slush, puddles and a wild freeze-thaw cycle, where the
only thing guaranteed is crater-size potholes. By the end of this month
the average high is close to 50F, but temperatures can range from
subzero to 80s.
With an average of 10.3 inches, March, once the snowiest month of the year, is now second only to January.
A
few inches of snow may fall on Tuesday, maybe 6 inches for southeast
Minnesota. A rapidly thawing atmosphere will push the storm track north
in the coming weeks, increasing the potential for moisture here. But by
the latter half of next week temperatures aloft should be warm enough
for rain. I see persistent 30s and 40s by the second week of March. It
still looks like the wicked winds of winter, a winter that hasn't been
that bad, will subside within 2 weeks.
Very yak-like, don't you think?
Potentially Plowable.
I'm not yet convinced the metro area is picking up 6" on Tuesday, but a
plowable, 2-3"+ slush-fest is possible, slowing down your commute a
bit, maybe enough to shovel, plow (and lead the news).
An Early Taste of Spring Fever?
One more cold front with subzero implications arrives Wednesday; 2 more
nights below zero later this week. No travel problems today or Monday
but Tuesday may be a mess with a few inches of snow, with could be
catastrophic, conisdering we're all forgotten how to drive on "snow". A
Pacific warm front arrives Friday; 40s may be commonplace next week with
a chance of "rain". So many new terms in the weather blog.
The (Mild) Ides of March.
500 mb winds (18,000 feet) are forecast to be zonal, blowing in from
the Pacific Northwest by mid-month. That should mean 40s, even a chance
of a few 50s within 2 weeks or so, temperatures aloft warm enough for
rain. I don't think March 2015 will in any way resemble March, 2014.
Too Early To Celebrate.
The (new) GFS model hints at 60F in roughly 2 weeks. Not sure I'm
buying that, at least not yet. We have a trace of snow on the ground and
even if we pick up a few more inches Tuesday most of that will be gone
by next weekend. If the sun comes out temperatures may surge into the
50s in about 12-14 days. Source: Ham Weather's Aeris Enterprise.
Alerts Broadcaster Briefing: Issued Saturday night, February 28, 2015.
*
Major icing event
possible Sunday afternoon, evening and early nighttime hours as rain
falls on ground temperatures colder than 32F. I-95 may be wet and
slushy, but many state and local roads from Baltimore to Philadelphia to
New York City will become icy during the late afternoon and evening
hours.
* Potential for major travel disruptions on land, and from BWI to PHL, JFK, EWR and LGA.
* Power outages possible as ice accumulates on power lines and transformers. Risk appears to be greatest in the Delaware Valley.
Major Ice Storm Potential.
Internal Alerts Broadcaster algorithms focus the greatest risk of
moderate to severe glaze icing from Baltimore and Wilmington to
Lancaster, Philadelphia and south Jersey late afternoon and evening
hours on Sunday. Graphic: Alerts Broadcaster.
Cities We're Tracking.

Why We're Concerned.
Model guidance shows the 32-degree isotherm staying south of Baltimore,
Philadelphia and New York City at 4 PM Sunday, increasing the risk of
significant accumulations of ice. Models print out .50 to .80" of rain,
and a significant percentage of that rain may freeze into glaze,
especially at the onset of precipitation Sunday afternoon. 4 PM NAM:

2015 Boston Blizzard Takes It's Toll On Region's Buildings. I found a story at
Architecture Magazine interesting - here's an excerpt and link: "
This winter has been a particularly tough one for those in the Boston area, which has experienced 31 days and counting of heavy snow, ice, and deep freezes. The severe winter weather has not only claimed several lives, but also a number of the region’s buildings—44 in a two-day span.
In particular, the unanticipated and extreme snow and ice loads have
taken their toll on the region’s roofs, causing them to sag, leak, and
collapse. The damage to municipal buildings can be seen through the
city’s drone footage..."

Doppler on your watch? People raised eyebrows when we (first) put
Doppler radar on cell phones back in 2001. Why on Earth would you ever
want that? Maybe in a few years (most) weather enthusiasts won't think
twice about checking their watches to see if rain or lightning (or any
threat) is lurking nearby. For now Aeris Wear is available for
Android phones only, and the basic version is free. A version for iOS and Apple is coming soon.

Who Is Hacking Whom?
Ham Weather uber-programmer and weather model specialist, Patrick
Francis, wrote a recent story that made me do a triple-take. Here's an
excerpt from
aplus.com: "
Modern
Media will "Hype" times that a massive hack occurs, such as Sony
Corporation, but does that tell the real story? For the last two months I
have tracked every attempted breach of my systems, stored the IP of the
attacker, and researched information about his or her country of
origin, city, company and so forth. The heck of it is, there's not a lot
that can be done with this information, because there is no one to
share it with who can do anything about it! :) Still, some people might
be interested to know a little bit about who is hacking who..."

Now
Americans have fewer children. Both parents often work and no longer
have time to linger over a serving of Apple Jacks and the local
newspaper. Many people grab something on the way to work and devour it
in their cars or at their desks while checking e-mail. “For a while,
breakfast cereal was convenience food,” says Abigail Carroll, author
of Three Squares: The Invention of the American Meal. “But convenience
is relative. It’s more convenient to grab a breakfast bar, yogurt, a

Climate Stories...
Is The Environment a Moral Cause? Here's a clip from a
New York Times Op-Ed: "...
People
think quite differently, however, when they are morally engaged with an
issue. In such cases people are more likely to eschew a sober
cost-benefit analysis, opting instead to take action because it is the
right thing to do. Put simply, we’re more likely to contribute to a
cause when we feel ethically compelled to. Still, why do liberals
moralize environmental issues, while conservatives do not? The answer is
complex, owing in part to the specific history of the American
environmental movement..."
Greenpeace Probe of Climate Naysayer Implicates Exxon Mobil.
BuzzFeed News takes a look at more implications of the Willie Soon sage; here's an excerpt: "...
The records
released Friday show that Exxon’s support of Soon came despite a 2007
pledge to quit funding climate naysayer groups, according to
Greenpeace’s Jesse Coleman, who started the Soon records search using
public records laws. “Exxon told us that they would stop funding climate
denial front groups,” Coleman told BuzzFeed News. “Years later, they
were still funding Willie Soon...”
Climate Oscillations and the Global Warming Faux Pause. Here's an excerpt of a story written by Penn State climate scientist Michael Mann at
Huffington Post: "..
.It
is true that Earth's surface warmed a bit less than models predicted it
to over the past decade-and-a-half or so. This doesn't mean that the
models are flawed. Instead, it points to a discrepancy that likely arose
from a combination of three main factors (see the discussion my piece
last year in Scientific American).
These factors include the likely underestimation of the actual warming
that has occurred, due to gaps in the observational data. Secondly,
scientists have failed to include in model simulations some natural
factors (low-level but persistent volcanic eruptions and a small dip in
solar output) that had a slight cooling influence on Earth's climate.
Finally, there is the possibility that internal, natural oscillations in
temperature may have masked some surface warming in recent decades,
much as an outbreak of Arctic air can mask the seasonal warming of
spring during a late season cold snap. One could call it a global
warming "speed bump." In fact, I have..."

Climate Change Might Be Causing These Huge Craters in Siberia.
VICE News has the story - here's the introduction: "
Reports
of new methane-eruption craters in the Siberian permafrost have piqued
the interest of scientists around the higher latitudes who see it as a
new sign of a warming climate. The first craters were identified in
summer 2014 in the natural gas-rich Yamal Peninsula, which juts into the
frigid Kara Sea more than 2,000 miles northeast of Moscow. They're
suspected to have been caused by eruptions of methane from beneath the
region's permafrost soil, which has been thawing during recent summers..."
