The status report shows a 60% change of weather not permitting a launch
on saturday and similar stats for sunday.

As I recall, the decision is usually made during the t-9 minutes hold.

Are there rules/procedures that cause NASA to decide on a no-go much
earlier ? For instance, if the weather service predicts a 90% chance of
weather prohibiting launch, would NASA still go ahead with the filling
of the ET (a rather expensive endeavour and one which is stressful to
the aluminium and foam) ?

I've seen NASA scrub a launch at the tanking meeting.
