When I looked outside this morning, it was about 32°F outside and raining. There was a thin layer of ice on the sidewalk, despite the fact that I'd thrown salt out last night. I tossed out some more salt and went back inside.
When I checked again around 1 PM, the temperature had climbed to 50°F and there wasn't a trace of ice anywhere. Even the deck, which I hadn't salted, was completely clear.
It's now 11:20, and the temp is still above freezing, 37°F.
Some ice storm.
