It has to be 32 degrees for ice to form. Frost is ice. Here, if it snows before the ground freezes, and the snow cover stays, the ground will remain unfrozen even in sub zero temps. So the snow insulates the ground from the colder temps. I would bet that, in the winter, the ceiling temperature and the floor temperature in my house can vary as much as 20 degrees. Probably more.

Yes. Yes it is.
Thanks Dennis. So are we saying that due to air currents, height and possible retained ground heat that my temperature readings are not representative of the actual temperature where the frost is occurring?
Jtrux, I'm still trying to wrap my brain around your theory. I think it my still be too early for that much science...
