Cold today, -18C/0F with a -30C/-22F windchill. After yesterday's high of 0C/32F during which there was some melting (if only because the salt had its chance to do its work), today, the sidewalks and paths had long stretches of frozen puddles along which I hopped off the bike and walked (no studs). This afternoon won't be much milder than this morning and tomorrow morning will be a lower air temperature but less forecasted wind so the wind chill won't be so severe. At least I'm back on the bike again, for at least part of the ride.
