it was about 15 below (wind chill)
Our weather warmed up considerably this afternoon for the first time in several days, so I washed my car; it was really awful-looking, with dirt and salt sprayed all over it. My hands did get a little cold. When I finished and came indoors, I found out it was exactly freezing. No wonder some of the water droplets turned to ice before I could dry them... I have since been officially declared unable to function in normal society.
