Forecast Discussion
Space Launch Delta 45
Surface high pressure will remain in control of the weather from the eastern Gulf of Mexico, the southeast US and the adjacent Atlantic waters. Low level moisture will continue to be rather limited so any cumulus clouds that are able to develop will be very isolated. The primary concern for launch day will be the Cumulus Cloud Rule. In the event of a 24-hour delay, conditions are not expected to change. The surface ridge remains firmly entrenched over the northeastern Gulf of Mexico. Once again, expect meager moisture available for cloud development. The primary concern for the back up day will be the Cumulus Cloud Rule.
