NASA'S SPACE SHUTTLE DISCOVERY LAUNCH RESET FOR SUNDAY

Erm, are there no windows in the morning then this time?
That is correct. The ISS orbit plane regresses westward so that the in-
plane time moves an average of 24 minutes earlier per day. So a particular
period that allows daylight launch and lit ET separation will always start
with a late afternoon launch, shifting gradually to a morning launch.
Seems to me
that in the afternoon at this time of the year, you are going to get
thunderstorms in the same sort of places later in the day.
Also correct. Can't be helped until NASA has validated its alternatives
(ground-based radar, wing-leading edge sensors) to return to night launch
ops.
