The Daily Parker

At least the sun is out:

We had days last year close to -17°C, but it was last this cold on 5 February 2009. Parker is bored, but even he didn't seem to want to stay outside this morning.

As an aside, because of the radiator in my living room the Inner Drive Technology Worldwide Data Center that I can't turn off, I have two windows open right now and it's still 24°C—3°C above normal—over by the server rack.

Should they go to year-round Daylight Saving Time? Scotland says no:

Britain currently sets its clocks at Greenwich Mean Time in fall and an hour ahead of that in spring. (New York is generally five hours behind Britain; Western Europe is an hour ahead).

The problem is that while a clock change might bring afternoon joy to London, it would condemn Inverness in the far reaches of Scotland — in relative terms, about 700 miles north of Montreal — to long, dark winter mornings with sunrises as late as 10 a.m.

Even worse, many Scots feel, it would mean giving in to English politicians. Though the devolution of British politics has given Scotland its own legislature and responsibility for many of its own affairs, the clock is still controlled by Parliament in London.

(You can see what sunrises and sunsets would look like up there at Weather Now.)

Daylight Saving Time has generated controversy for almost a century now, with good and bad arguments on both sides. I'm almost indifferent, though I do get annoyed waking up in the dark at the beginning of November.

Forecasters predict Chicago will get down to its coldest temperature so far this winter, -19°C, overnight:

What arrives Thursday night and Friday morning on gusty northwest winds is but a lobe of cold air off that vast wintry reservoir of air. If there's one piece of good news which accompanies the cold blast, it's that the chill is to hit hard for a day and a half then back off, giving way to a more moderate brand of cold air this weekend. But, while its stay here is to be comparatively brief, the near -18°C low temperature predicted at O'Hare is to be accompanied by 24-32 km/h sustained winds likely to generate dangerous wind chills under 20-below---and potentially as low as 30-below in a few of colder locations north and northwest of the city.

But on this day in 1985 we experienced -33°C, the coldest temperature recorded in Chicago. If I recall correctly that was one of only two days in my four years of high school when they closed the school for weather—because they couldn't start the buses.

At least the snowstorm pounding the central U.S. will miss us.

This time of year Chicago residents can easily forget the planet orbits an actual star that gives off actual heat and light. This month hasn't helped a bit:

If you're susceptible to SAD---Season Affective Disorder---a form of depression brought on by winter's short days and lack of sunlight, the past 9 days (since Tuesday, January 11) have no doubt been especially rough. The period has logged only 10 percent of its possible sunshine, we're told by veteran National Weather Service observer Frank Wachowski---a total of just 7.9 hours.

Under the best circumstances, a typical January is not one of Chicago's sunnier months. But this month's abysmal 10 percent tally falls far short January's average of 43 percent of its possible sun. That means Chicago area residents have seen less than a quarter of January's typical sunshine.

But good news! We'll have a couple of sunny days later this week. Yes, once that cold front passes and that pile of cold, dry air pushes on through, we'll have plenty of sun—and -16°C temperatures.

Sigh.

Update, 13:56 CT: Look! Up in the sky! It's...it's...the sun!

It turns out, December was a lot colder (relatively) than the rest of 2010:

So after nine months of above-average temperatures, including three in the top-10 warmest in recorded history, we got December, in the top decile of coldest months. I'm happy about the last two days when we had a brief, spring-like spell of 10°C temperatures, but wow, what a tease.

Happy new year, Chicago; winter's back:

Welcome to the semi-annual update of the Chicago sunrise chart. (You can get one for your own location at http://www.wx-now.com/Sunrise/SunriseChart.aspx.)

Reader MB sent some art from Murphy, N.C.:

She writes:

[I] saw your request for winter wonderland pictures on Facebook and thought you may be interested to see what Murphy, N.C., looked like during the past few days. We were supposed to get a max of 8 cm on the 25th according to initial reports, but I think the total was closer to 40 cm as of 10am [Monday] morning when the sun finally decided to show its face.

Meanwhile, the rest of the East Coast continues to dig out. Today's snow pack map from NOAA's snow center still shows pretty heavy coverage from Maine to the Carolinas:

I've just pushed out an interim build of the Inner Drive Technology demonstration project, Weather Now. In addition to fixing a couple of annoying bugs, I added a significant new feature. The weather lists on the home page now can show whatever text I want for the weather station names. Before, it could only show their official designations, which made the lists harder to use.

You can see how useful this is immediately. The list of NFL football games now shows you what game the weather goes with. Also, I added arbitrary sort ordering and station begin/end times, so the lists you see today may not be the same as the lists you see tomorrow.

These features take the site a half-step closer to the next major release, due at the end of January, that will allow you—yes, you—to set up your own lists. That feature set will take a while to develop, which explains why I wanted to get this half-point release out first.

Yesterday's storm, which right now has parked itself over Cape Cod, dumped 80 cm of snow on parts of New Jersey and pretty much shut down New York:

Morning commuters faced the daunting prospect of cutting fresh tracks in over a foot of snow along roads and sidewalks that looked more like Colorado than the urban north. In New York City, a badly crippled subway system hobbled along, but Long Island Rail Road service remained suspended early on Monday, as did some New Jersey Transit and Metro-North Railroad lines.

The storm’s timing was diabolical — too late for a white Christmas, but just in time to disrupt the plans of thousands of people trying to get home after the holiday, return unwanted gifts or take advantage of post-holiday bargains at stores. Public schools were not in session, much to the dismay of many children.

By 7 a.m. Monday, 50 cm covered Central Park, according to the National Weather Service. The deepest snow was recorded in Elizabeth, N.J., where 80 cm fell. By sunrise, the storm had largely moved on from New York City, heading northeast out past Long Island and up over Nantucket, gradually weakening, the weather service said.

I'm hoping friends out East will send photos. Meanwhile, here's one from the New Year's Eve storm 10 years ago, on 30 December 2000:

I know this will incite some regular Daily Parker readers, but we should get used to storms like this more often. They're a predicted consequence of climate change.
