Brrr!


Merriam-Webster doesn't address this term we so often employ at this time of year. But the Internet seems to think three R's is appropriate, so I'm going with that.

Well, it’s been cold here in Chicago – again! But that's no surprise.






When we moved here in 1983-1984, a friend in who grew up in Sterling, Ill., warned us that it was a lot like Pittsburgh only more severe. He was right.

The hot, muggy summers are a lot more so, as are the bone-chilling cold winters. So, this year’s polar vortex, for which one local TV station noted Chicago was the vortex, came as no surprise. Cold as can be and lovin’ it (more or less).

It all brings back memories of our earliest Chicago winters, when we had just moved here from the more temperate climate of Pittsburgh.

During the winter of 1983-1984, and the year after as well, I was making the 75-mile commute each day from Palatine to Braidwood with Jay Johnson. We would leave early in the morning to arrive at Braidwood by 7 a.m., then set out on our return about 4 or 4:30 in the afternoon. Working in a warehouse temporarily converted into office space, there were days we never saw the sun in that bleak midwinter.

Because of the extreme cold of 1984 and 1985, whoever’s turn it was to drive also ended up going out to start the car at lunch time, letting it run long enough to warm up and make sure things didn’t freeze up on us in the course of the day.

And so we revel, once again, in extremes, and anxiously await the spring thaw. Enough is enough; come on, spring!

This is a good week to sleep in

The 2018 winter solstice (the shortest day of the year) is now safely behind us. But strangely enough, sunrise continues to occur later and later for a few days beyond the solstice. It's at its latest7:21 am–this week, from January 1 through 6, and only then does it turn the corner and begin coming earlier each day.

However, even before the solstice, sunset also began to move later in the day (the earliest sunsets were from Dec. 6 through 12 at 4:20 pm). And next week, when sunrise and sunset both again are diverging, we may begin to sense that spring is coming.

These times and dates are specific for Palatine, Illinois, varying slightly for even nearby towns and villages, and more for places further away. But the pattern is similar (at least in the northern hemisphere.)

Tables of sunrise and sunset times are available by city and state (and international locations, too) on the U.S. Naval Observatory website at https://aa.usno.navy.mil/data/docs/RS_OneYear.php.

See the full-size table for Palatine here.

By the way, the USNO folks offer a much more complete explanation of this phenomenonthree explanations, actuallyat https://aa.usno.navy.mil/faq/docs/rs_solstices.php. It's worth a look.
