Yes it was either rain or some other wet phenomenon...All of the railings and deck were snow covered last night, when I woke up they were slush, and it was misting out.
Edit: It's hard to see from this pic, but that railing had snow on it last night, now it is just an inch of slush. Slush on the deck as well, and the table was all snow, and now slush. I don't know if being on the lake has anything to do with it, but I will drive away about a mile from the lake and there will be a clear difference in temperature and increased snow amounts after some storms.
