The neighbor across the street is getting his Fiat X/I/9/ out of the garage and taking it for a ride. Sure sign of solid warm weather. The old Annotated Thermometer joke was too optimistic about Italian cars!
Sidenote: This version of the Annotated Thermometer is unfamiliar. The version I’d seen before had a roughly equal range above and below freezing. This one seems to have been written by physics types, with lots of detail WAY down low, finishing off at Absolute Zero, -465F. “All motion impossible, molecules cease to exist, Minnesotans admit it might be a bit nippy.”
