I went out to feed this morning (4 AM) and saw a pretty heavy frost on the truck.
Came back inside and checked the temperature. Both my unit by the door and my Davis weather station showed about 40. The Davis chart showed that it had stayed above 40 all night.
Maybe I've not been paying attention, but I'm wondering how there could be frost at 40 degree temps on a black truck. My thinking is that the truck should have had some residual heat from the day which should keep it frost free down to below 30.
So, how could the truck have frost on it if the temperature never got down to freezing?
(Maybe, it has something to do with same statistics as covid-19?)
