Weather update:  Currently evaluating one constraint on lightning energy dissipation.  Expecting an update at T-20min.  Will know whether to continue or scrub at that time.

"Unless you can give us another 10 minutes, I don't think we can get there by the weather rules today.  We'd be clear by 1645 local, but not by this T-0 today."

Will inform the crew of a call at T-17 minutes.  Clocks still ticking.
NO SCRUB AS OF YET.

Nice venting. Weather might have been good 10 minutes later than the scheduled time.
