Reception of HDTV is driven by a combination of factors. Signal to noise, ghosting and interference are major ones. A windy day can make for rapidly changing ghost conditions, and the ghost cancelling system in the receiver might not be able to keep up. The transmitter tower bouncing around in the wind, trees swaying and so on. Movement can be a substantial fraction of the carrier wavelength up in the UHF TV band.
