The Foehn influence don’t usually develop rain, snow or even thick clouds about the upwind aspect. When there isn't any precipitation to the upwind aspect, Which if any clouds they may have evaporated, then the temperature among the two sides with the mountain vary are the exact same for a similar altitude.
