Here's more info about the Anvil Rule for launches and why it causes a NO-GO: http://weather.about.com/od/thunderstormsandlightning/f/anvi...
The launch is a no-go because an anvil cloud (thunderstorm) entered the 10 mile radius around the launch site. Prior to the scrub there were a few comments about a cloud being close to the exclusion zone but not yet in it.
