weather
Interesting recently-observed phenomenon. Where I live, the temperature is very very cold in the mornings though warm in the evenings. Since I live 70-75 miles north of New York City, this makes getting dressed for work a kind of tricky business what with a long commute and all. So I decided to see if there was any reality behind my sense of things. I put weather.com's banners on the bottom of this blog, one for NYC and one for Dutchess County. What to my wondering eyes should appear but the fact that temperatures are 10-20 degrees apart in the mornings, 5-15 degrees apart in the late evening with Dutchess the colder by far but that from around noon until evening, the temperatures are identical with Dutchess County often warmer. The Hudson Valley is a valley so I assume some of the explanation has to do with trapped sunlight and all that. But it used to be consistently colder than in Manhattan even in the summer when the Hudson's waters would presumably have tempered things. By the way, one of my commuting pals lives 20-25 miles north of me and the temperature there is consistently 5-10 degrees warmer than where I live. Pretty wild, eh? Now to find us a geologist and/or a weather student to explain all this.

Comparing weather/climate of localities can be intriguing. Out of curiosity, several years ago, I compared my hometown of Knoxville, TN to Cincinnati, OH where I now work.

Cincinnati is about 250 miles due north of Knoxville but Knoxville has a greater record snowfall. The record lows are the same (-24 F, brr). Cinci gets a little more snow on average but not much. I had always thought Cinci would have been much colder and gotten a lot more snow but not so.

My guess on the snow is that Knoxville is up against the mountains which slow down the weather fronts some while the area around Cinci is flat and weather patterns blow right by.
