Today's wind-chill RealFeelTm low: -5F.
Tomorrow: about the same, except windier.
Number of layers I had to wear outside today: way too many.
Joint motion lost at shoulders and elbows: most of it.
Expected duration of cold snap: through Sunday.
Stuff I left in the car: significant.
Chance I'm going back for it tonight: none.
Additional insult: my thermostat needs servicing. I have heat, but I have to turn it up to over 75 before anything kicks in.
