No confirmation yet, but judging from countdown clocks at nearby KSC, SpaceX is now targeting midnight (0400 UTC) for #Falcon9 liftoff from CCAFS.

Weather radar from KSC.  Non-professional opinion: sketchy.

A lightning advisory has been issued at the Kennedy Space Center after several storm cells popped up in the last few minutes over Cape Canaveral. The countdown clock continues ticking toward launch time of 12 a.m. EDT (0400 GMT).

T-minus 70 minutes and counting. SpaceX is holding off fueling at this time as foul weather impacts Cape Canaveral.
