      I was thinking the same thing, but here’s my guess:

      -Cold, foggy night/morning = frost forming

      -Cloudy until early-morning so the sun doesn’t warm the shingles

      -Clouds clear up a bit by mid-morning, and the sun rapidly warms up the shingles, leading to the frost evaporating quickly relative to the shadow’s motion

        That’s what NASA wants you to believe, so you don’t investigate the fridge they put in your attic where they store your precious bodily fluids.

        But sure, water sticks to a spinning ball.
