Forecast Discussion

Space Launch Delta 45

Moisture plume lifting north in combination with the sea breeze collision is triggering showers across interior Florida this evening. While most of this activity is expected to remain west of the Spaceport, a few light showers may drift towards the area late this evening as prevailing flow becomes more southwesterly. Monday will be another warmer than normal day across Central Florida with breezy southwesterly flow ahead of a weakening frontal boundary sliding into the state. The prevailing flow should result in a stronger Gulf sea breeze, pushing towards the east coast late into the evening hours and interacting with the Atlantic breeze. The late day sea breeze collision is expected to drive shower development along the coast through the early portion of the launch window. In addition, the approaching front will drive an increase in mid and upper level cloud cover. The primary weather concerns for a launch attempt Monday evening will be thick clouds associated with the boundary and cumulus clouds associated with sea breeze showers.
