Forecast Discussion
High pressure is beginning to build back across the area in the wake of the weekend front. The associated low will continue to move up the eastern seaboard as it weakens. As this happens, winds have weakened over the Space Coast area, and will begin diminishing over the recovery area. Onshore winds will develop as we approach launch day and this will begin to increase low level moisture across the area. These winds are expected to be in the 5 to 10 mph range during the launch window. The primary concern will be the Cumulus Cloud Rule. In the event of a 24-hour delay, winds begin to increase as low pressure develops over the Central US and begins to move into the Ohio Valley. With the increased winds, moisture will likewise increase over the area. This will help to support broken cloud conditions, and it is possible that there could be a thick cloud concern. Southerly to southeasterly low level winds are expected to be in the 12 to 17 mph range with the possibility of isolated gusts into the lower 20s mph. The primary concern for the backup day is from the Thick Cloud Layer Rule and for Liftoff Winds.
