As "Chicagoans gaze out at a cover of snow for the 21st consecutive day" today, I'm once again in Raleigh, where snow fell once a few weeks ago but decided not to stay the night. It's already 9°C, going up to a predicted 16°C this afternoon. I plan to walk as far as my legs will take me (or Parker's will take him) later on.
That's the problem, of course: in Chicago, we get maybe three days like this between November and March, so I'm a little giddy about it. On the other hand, Chicagoans do get a lot of work done in the winter. Probably because we have no opportunities to play.
Apparently I got back to Chicago just in time for a heat wave:
Arctic air's grip on Chicago's weather enters its 19th day Tuesday. But far-reaching changes in critical upper level steering winds taking place on a continental scale are to undermine the frigid air's dominance. The break in arctic-level temperatures may span much of the coming two weeks. Not until month's end may bitter winds of arctic origin return brutally cold air to the metro area.
Coming days will offer winter weary Chicago area residents a noticeable respite from the bitter air at the heart of January's 13.9-degrees average temperature to date--a reading more than 5°C below normal. But the "warming" predicted which is to include the city's first above freezing afternoon readings since Christmas (Dec. 25), may occur a bit more slowly than many might hope.
Today the temperature at one reporting station (Waukegan) did, in fact, go all the way up to 0.6°C, but alas the city's official high today looks like 0°C on the nose.
Bonus: A propos of nothing, here's a set of outtakes from ABC's Better Off Ted (NSFW). Worth a chuckle.
Via several sites, a NASA photo of Great Britain from Thursday noontime:
The U.K. doesn't usually get a snow cover at all, let alone one this thorough. The U.K. Met Office has an explanation:
In most winters, and certainly those in the last 20 years or so, our winds normally come from the south-west. This means air travels over the relatively warm Atlantic and we get mild conditions in the UK. However, over the past three weeks the Atlantic air has been ‘blocked’ and cold air has been flowing down from the Arctic or the cold winter landmass of Europe.
But not this:
The Chicago area was bracing for a long, hazardous evening rush hour as it continued to be socked by a major snowstorm that has canceled more than 500 flights, closed more than 150 schools and caused numerous spin-out accidents on expressways.
The Illinois State Police is warning of "extreme travel times" for the rush hour.
Tonight also will turn bitterly cold with wind chill values as low as -17°C to -24°C.
Today's high temperatures are expected to be [around -5°C].
At the peak of the morning rush hour, travel times on some expressways were well over an hour above the norm. Travel conditions are expected to be worse this evening as winds pick up and snow begins to drift across roadways.
Like I said yesterday, Chicago weather builds character—but I have enough for now, thanks.
It turns out, Raleigh isn't that cold. All my life I've just accepted that Chicago winters build character. But I'm not sure anymore, especially after three sunny, 5°C days here while temperatures back home have skulked around -12°C. Then, today, this:
A winter storm warning will be in effect across the Chicago area from this evening through Friday morning.
By the end of that warning, anywhere from 15 to 30 cm of a fairly fluffy snow will have come down, according to the National Weather Service. The heaviest snows are expected near the lakefront.
... The heaviest snowfall will occur between noon and 6 p.m. Thursday, with snow falling at about an inch an hour, [said Charles Mott, a meteorologist with the National Weather Service].
Forecasters predict snow in Raleigh tonight, too: about 1 cm or so. Of course, that amount could halt all commerce in North Carolina, so we'll be stocking up on bottled water later.
Seriously, though, Raleigh averages 19 cm of snow annually; Chicago, 98 cm. Then there are the normal temperatures of both cities. I'll say nothing else right now except that the average January daily high temperature in Chicago is the average January daily low temperature in Raleigh.
Let's see how I like Raliegh in July. But today, it's fine.
Since I'm spending so much time here, I thought I should do a
Raleigh sunrise chart to complement the one
for Chicago. (You can get one for your own location at
http://www.wx-now.com/Sunrise/SunriseChart.aspx.)
An interesting note about 2010: the sunset on November 6th will be the latest sunrise
for most places in the U.S. (7:43 am in Raliegh) until 2021.

...could be today, depending on which competing definition you use:
A blue moon is a full moon that is not timed to the regular monthly pattern. Most years have twelve full moons which occur approximately monthly, but in addition to those twelve full lunar cycles, each solar calendar year contains an excess of roughly eleven days compared to the lunar year. The extra days accumulate, so that every two or three years (7 times in the 19-year Metonic cycle), there is an extra full moon. The extra moon is called a "blue moon." Different definitions place the "extra" moon at different times.
- In calculating the dates for Lent and Easter, the Clergy identify the Lent Moon. It is thought that historically when the moon's timing was too early, they named an earlier moon as a "betrayer moon" (belewe moon), thus the Lent moon came at its expected time.
- Folklore gave each moon a name according to its time of year. A moon which came too early had no folk name – and was called a blue moon – bringing the correct seasonal timings for future moons.
- The Farmers' Almanac defined blue moon as an extra full moon that occurred in a season; one season was normally three full moons. If a season had four full moons, then the third full moon was named a blue moon.
- Recent popular usage defined a blue moon as the second full moon in a calendar month, stemming from an interpretation error made in 1946 that was discovered in 1999. For example, December 31, 2009 would be a blue moon according to this usage.
So, it's possible today's full moon is a blue moon. Or it's possible the next blue moon will occur November 21st. Or after some volcanic eruption which hasn't happened yet.
Regardless, enjoy it if you can. It only happens...infrequently.
It's time for 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.)
An interesting note about 2010: the sunset on November 6th will be the latest sunrise in Chicago (7:30am) until 2021—and that, only within 4 seconds of precision.

I'm leaving this:
For this:
THE NATIONAL WEATHER SERVICE IN CHICAGO HAS ISSUED A WINTER
WEATHER ADVISORY FOR SNOW...WHICH IS IN EFFECT UNTIL 9 PM CST
THIS EVENING.
At least I'll get there earlier than planned. I tried to get on the 11:30, but because the 7:30 had left at 9:30, and the 9:45 was delayed, they put me on the 9:45 which actually leaves (we hope) at 11. So instead of 7 hours at home before traveling again tomorrow, I get 9. I hope.
Update: Well, the 9:45 actually now leaves at 1pm, in theory, leaving me almost exactly no better off than the original plan. We'll see.
