17° for my ride into work this morning, with a 17 mph south wind dropping the windchill down to 3°.
fortunately, roughly 75% of my morning route is due north, so that was a nice ripping tailwind for me.
unfortunately, part of the bike path through Skokie had been plowed but not salted, so it was an icy mess.
with the late start i got + the icy mess slowing me down, i was 20 minutes late for work....... whoops.
