Forecast Discussion
Surface cold front that is moving across the Space Coast this morning will continue southward across Florida through the day on Friday. Behind the boundary, high pressure will work its way across all of Florida bringing slightly cooler temperatures and onshore winds. Skies are expected to clear with perhaps only a few stray cumulus clouds across the area…and most of those will likely remain out over the coastal waters. The primary weather concern for launch day is the Cumulus Clouds Rule. In the event of delay, the weather doesn’t change very much across the Space Coast region. High pressure remains in control across the area but the surface pressure gradient tightens slightly producing a bit stronger winds. Clouds are not expected to be very widespread over the area but there will be a slight increase from Sunday morning. Winds are expected to increase over the Space Coast region as well as the recovery area. The primary concerns are the Cumulus Clouds Rule and Liftoff Winds.
