Snow is an insulator. It is a poor conductor of heat due to its low density and the great amount of trapped air in between the snow crystals. ... Distilled water is not a good conductor. Since snow is relatively pure water, and coupled with its low density and great deal of air, 
it is a poor electrical conductor.
