While I don't know if seeing conditions can be predicted, I do firmly believe that the likelihood of good seeing is inversely proportional to the cost and/or desire to use your most recently purchased astronomy item. Ie: the higher the cost or the greater the desire the longer it will be before conditions stablize. That is of course after the clouds clear.
This is bought about by the generation of negative ions from excessive anxiety/twitchiness over how long before these "damn clouds disappear". In other words its the planets way of telling us to "Chill out. You'll get to use it when I'm good and ready to let you use it"
Mother nature is never cruel but she does have a certain implacability about her
