Forecasters predicted a 70 percent chance of stormy weather triggering a launch delay tomorrow, though the forecast improves slightly to 60 percent ‘no go’ Saturday and then to 40 percent on Sunday.

"As you can see outside, the clouds have rolled in, we're starting to see some showers. We even had a thunderstorm show up this morning. So we are expecting more of this for the next couple of days."
