Just so you are aware, the reason for postponement during bad weather is for instrumentation and publicity photographs, not because the system will not work. The intercept was in outer space, no weather there, and the missiles fly quickly through ground weather. Just so you know.
Huh? The instrumentation radars that record the details of the exo-atmospheric hit certainly will perform better when the weather's good, but I don't think publicity photos of a night launch in Kwaj would be a consideration. With the survival of the BMD program and a (well deserved) half billion dollar bonus on the line... getting a good photo for the press release was surely the last of among about 5000 things to be considered.
