r/SpaceX Launch Weather Review
(15:10 UTC)
Weather-wise, so far everything looks pretty good, with showers, storms and cloud debris well away from the zone around the pad.
However, on days like these where the main threats are primarily diurnal convection which evolves quickly and unpredictably, we'll only really get a better idea within an hour or two from launch, at least beyond the 45th's mesoscale forecast and 70% GO.
(17:00 UTC)
With less than two hours to go until launch, the weather is still looking pretty good around the pad, better than yesterday so far, with showers and storm cells still keeping generally well clear of the 10 nmi/19 km zone around the pad, and like yesterday, cirrus blowoff from storm anvils to the west causing high-level cloudiness but seemingly well removed from their source such that they should not preculde launch.
(18:30 UTC)
Looks like there's just one modest cell that's the problem, that looks to pass directly over the pad. It should be on track to clear the area by the new scheduled launch time, but there are a few others downstream that may intrude on the party.
