That's what's confusing. Everything I've read about frost says it's commonly confused with meaning 'freeze' when in fact it needs to freeze for frost to occur.

That's just what I've read. Me I've never had any problems with a frost, only with freezes. 33 degrees and my bananas are fine. 32, eh, not so good. 31, bye bye fronds.

So I don't know. I always thought frost was in low areas that act as pockets, trapping descending colder air, similar to an area that is low, like a delta, compared to hillsides because the cold air sinks.

But then getting frost on a wind shield without a freeze happening...so obviously something gets colder than other things.
