Forecast Discussion

Space Launch Delta 45

A surface low is tracking offshore the northeastern Florida coast this morning, with its associated front on the doorstep of the Spaceport. Most of the frontal rainfall has pushed south of the area, but the front itself will arrive in a few hours as it pushes through the remainder of the Florida peninsula through the afternoon. As the low pulls further out into the Atlantic, it will bring a secondary boundary through late this evening. Breezy northerly wind shift with this feature will usher in low-topped stratocumulus and a few sprinkles after midnight. The primary weather concerns for an early Thursday morning launch attempt will be a small threat for cumulus cloud violations. High pressure over the Gulf of Mexico behind the front will be quickly reinforced by a stronger high moving south across the Midwest and eastern seaboard on Thursday. Onshore flow will moderate temperatures, but expect a seasonably cool and sunny day across the Spaceport that will translate into a mostly clear night. The primary weather concerns for an early Friday morning launch attempt will be a small threat for cumulus cloud violations with any Atlantic clouds.
