So far as I know, wind chill is pretty much irrelevant when it comes to plants 
and other life forms that are not warm-blooded creatures.  Wind-chilll provides 
an estimate of how we perceive the cold, but the measured temperature on the 
thermometer is still  the temperature experienced by trees.  Winds can affect 
plants by increasing desiccation, especially if winds persist over long periods 
of time, but I don’t think a single night of very low wind chills will have 
much impact on dormant trees.  With very cold nights and high winds, I suppose 
there could eventually be some freeze-drying effects, but I don’t think I’ve 
ever heard much about that kind of damage on trees?

Does anyone have a handle on how wind chill relates to fruit bud critical 
temps.  We are expecting -11F tonight with a wind chill effect of around -30 F.
