Forecast Discussion

Space Launch Delta 45

High pressure centered across the northern gulf coast will shift northeast into the Deep South, reaching the western Atlantic on Wednesday. While the weather will remain pleasant overall, mid-level vorticity in the Gulf of Mexico will create a weak shortwave trough south of the ridge. This will bring increased mid and upper-level cloud cover through the Florida Peninsula Wednesday, along with breezy winds out of the northeast. As a result, the main concerns for the primary launch window will be for Liftoff Winds and the Thick Cloud Layers Rule. On Thursday, high pressure continues drifting northeast, but elongates across the western Atlantic as mid-level vorticity persists across the peninsula. The Space Coast will remain on the southern flank of the ridge. The tightening pressure gradient will likely increase winds out of the east as mid and upper-level cloud lingers across the state. The main concern for the backup launch window will again be for Liftoff Winds and the Thick Cloud Layers Rule.
