The temperature here at Inner Drive Technology World Headquarters peaked at -5°C, the warmest we've had since 2:30pm on Thursday. Next Thursday it'll hit 10°C, which is 32°C (57°F) warmer than Saturday's overnight low. Welcome to Chicago in the era of rapid climate change.
I hope we don't get any more really horrific cold snaps this winter, but I expect we will. For now, though, I'm going to take Cassie on the longest walk she's had in almost a week.
