Forecast Discussion

Space Launch Delta 45

An area of low pressure off the coast of the Carolinas will slowly move northeast through the day as a weak wave located in the Gulf of Mexico will move eastward across the central and southern portions of the state, bringing some spotty showers overnight and into Thursday morning. Much of the upper-level moisture associated with the wave will move off the coast by midday, leaving only low topped showers along the front to the west by the launch window. Therefore, the primary launch weather concern is the Cumulus Cloud Rule associated with any showers that may develop ahead and along the front. Expect much drier, cooler conditions Friday as high pressure builds in, so the sole launch weather concern for the backup attempt will be Liftoff Winds.
