SpaceX scrubs third Dragon flight due to weather, will try again Thursday

6:30pm ET Wednesday Update: SpaceX took the countdown down to T-30 seconds, but at that time the company had to scrub the launch of its Falcon 9 rocket due to poor weather conditions. Inconveniently, a fairly large thunderstorm complex moved over the launch site just as the clock was counting down.

The company will now try to launch again on Thursday, at 6:01pm ET (22:01 UTC). However, the forecast for Thursday is not particularly great either.

Original post: The rocket is ready. The Dragon spacecraft is ready for its supply run to the International Space Station. But Mother Nature may not be ready for the launch of a Falcon 9 booster on Wednesday evening from Florida.
