Forecast Discussion

Space Launch Delta 45

Forecast Discussion: A cold front pushed through the area this morning and will stall out across southern Florida throughthe weekend. The highest chances for precipitation will be along the front itself, with coverage likely peaking tonight into tomorrow morning, alongside east-northeast gale conditions. For tomorrow, models show the boundary and highest rain coverage settling just to the south of the Spaceport. Even with the front’s position, there will be enough low level moisture for isolated onshore-moving Atlantic showers during the primary window Sunday afternoon and evening. The elevated winds are expected to gradually decrease throughout the day tomorrow and will likely be close but just below liftoff constraints by the launch window.Though winds continue to diminish Monday as the post-frontal high settles south and the gradient relaxes, the general pattern will remain the same but with slightly higher shower coverage and deeper moisture. Thus, the threat for onshore moving Atlantic showers will continue into the backup window Monday afternoon and evening.
