I didn't have a thermometer but it was bloody cold.
Back roads have compressed snow, but it's not a big problem because it hasn't thawed and refrozen into ice, just stayed as compressed snow, which is actually quite grippy.
Main roads are a bit slushy in places, but salted and mostly cleared.
I also had trouble with my bike. My tourer has treaded tyres, so I fixed our new helmet camera thingy to that, and then found its gears and chain were frozen solid from Saturday's outing. Ten minutes later, I had one working gear...
I would have taken my fixie, but its slicks are a bit slippy and I didn't want to have to switch the camera over.
