There's a credible ear witness account that would support your theory I saw on Live Leak earlier. The witness mentions the area's "micro climate" and previous history of cloud settling in the bowl of the crash site.
If you go to LL and search "Witness Describes What He Heard Before Kobe Bryant Helicopter Crash". I can't post the link because I'm a noob.
