Good observation by the Times today that the Biography billboard and the digital thermometer a block away tend to show different temperatures. I've been under the impression that the Biography billboard takes its reading directly from Central Park. However, this morning it showed a temperature of 35 when the latest hourly observation from Central Park was 31. So while the other display looks too cold, the Biography sign seems to have a wrinkle also.

Speaking of temperature data, I downloaded a piece of Mac freeware to report the latest Central Park temperature right on my desktop. I set it to update every 2 minutes--not because a new reading is available that often, but because I wanted to be sure it caught the hourly update (at every 51-after-the-hour) quickly.

At 12:12 p.m., this display said 32, the same temperature as at 11 a.m. But the 11:51 a.m. reading at Central Park was 33. That was the dealbreaker right there. What's the point of setting it to update every 2 minutes if it misses the new observation? I've disabled this "Weather Grok" freeware for now.
