Another perfect day in Chicago

I've spent the morning on the Weather Now tasks generated by last month's architecture review and this past week's component updates. It looks like I'll get the next Weather Now release out on Wednesday, depending on how much the weather distracts me.

Today it's going to distract me from about half an hour from now until the late evening. It's 24°C and sunny with lower humidity (dew point 15°C) than we've had in weeks. And the forecast for the the week ahead fails to suck:

Today: Mostly sunny, with a high near 23. North wind 15 to 20 km/h, with gusts as high as 30 km/h.
Tonight: Mostly clear, with a low around 17. Northwest wind around 10 km/h.
Monday: Sunny, with a high near 23. West wind 10 to 15 km/h becoming northeast in the afternoon.
Monday Night: Mostly clear, with a low around 17. East northeast wind 5 to 10 km/h becoming southwest after midnight.
Tuesday: Mostly sunny, with a high near 26. Southwest wind around 10 km/h becoming south southeast in the afternoon.
Tuesday Night: Partly cloudy, with a low around 19.
Wednesday: A 40 percent chance of showers and thunderstorms after 1pm. Mostly sunny, with a high near 28.
Wednesday Night: A chance of showers before 1am. Partly cloudy, with a low around 20.
Thursday: Sunny, with a high near 26.
Thursday Night: Mostly clear, with a low around 20.
Friday: Mostly sunny, with a high near 24.
Friday Night: Partly cloudy, with a low around 19.

I mean, really? OK, Wednesday doesn't look perfect, but it does look like a good day for a software release.

Cassie seems to have recovered from yesterday's 8 km walk. I have no doubt she's up for a pair of 4 km walks this afternoon. We're about to find out.

I also wanted to flag an historical anniversary: On this day 170 years ago, Eunice Foote published the first paper on human-caused global warming based on her observations of carbon dioxide and water vapor in controlled atmospheric conditions. She made the correct inferance that burning coal and oil would lead directly to increased global temperatures. Good thing people listened to her, else we'd be seeing all kinds of problems today.
