For anyone who is interested, here is the http for a personal weather station (from weather underground) located on Park Point, half way between the two favored launch sites. It gives almost realtime and graphed historical wind data. This weather station tends to be more reliable than Sky Harbor as it has a clear shot from all directions. - You may need to delete part of tail of the address to make it work.
