"Wind chill" has nothing to do with evaporation, however. There is
very little water on the surface of the skin in the Winter (my dry
skin is evidence ;-). OTOH, any evaporation won't just make it feel
colder it will *make* it colder.

Only to a point though. Wind chill is commonly reported to be 20 degrees
colder than ambient this time of year. Evaporation is not going to lower
temperatures that much when the air is this cold. Cold air does not hold
moisture like warm air does, so evaporation is not the same factor that it
can be in warmer air.
