Actually, the humidity in Phoenix is almost never that high with those high temperatures. During the monsoon, the dew point rises to the mid 50's but the humidity stays quite low. What happens many times during the monsoon season is that the dew point rises and moisture in the atmosphere causes precipitation but tends to evaporate, "virga", because the humidity is much to low to sustain moisture. During the monsoon season, when the humidity rises relatively high in Phoenix, usually around 34%, the temperature drops into the low 90's. However, most monsoon storms occur at temps between 100-108 and relatively low humidity, in the teens and 20's. Furthermore, after the formation of the thunderheads, the passing of the dust storm, "haboob" in arabic, then the temperature drops dramatically and the humidity rises causing heavy rains and flash flooding that is infamous in Phoenix. Last August late during the month, I remember because this was the time I moved to Phoenix, I was swimming in my parents pool with friends and it was hot, 110 at noon I believe. We saw to the east cloud formations and about 30 minutes later ran into the house as the dust storm engulfed the city. It was awesome and my friends from the NE loved it and took so many pictures.
They were so intrigued that they turned on the weather channel,LOL! The temps dropped from 110+ to the 90's, then into the 80's with 40% humidity or more a few hours after the monsoon storm began. It was very cool and I loved the dramatic change, that doesn't happen anywhere in the U.S. on a regular basis, only in Phoenix! OK, have to go my neighbors and my dog are yelling and yelping at me. :-)
