People don't realize the power of wind and direct sunlight. Temps don't have to reach 32 for the ice to melt. The asphalt and concrete absorb heat and will melt the ice. Then the dry air helps it evaporate.

I can hear it melting and dripping off the roof right now and it's in the 20s. The roof is absorbing heat like the road.

Roads in cenla this morning were as dry and clear as they could be. Was really surprised because they were still wet yesterday afternoon. I did not have to cross any bridges, so can't comment on that.

Could one get frostbite or frost nip from a single digit wind chill, or does it have to be like -15 or colder wind chill to be dangerous to exposed skin? Saw several people outside without hats or ski caps protecting their ears.
