RG is correct in that rising air cools and condenses and is the reason you'll see mountain areas that just seem to "grow" clouds as if they are not coming from anywhere. However, I've witnessed countless times on my winter weekly trek through Franconia Notch the temperature increase 8-10 degrees when a south wind in blowing up the notch. Believe me, I've watched this for 30+ years of driving through FN every winter weekend.
