Forecast Discussion

Space Launch Delta 45

As the front moves further northeast, high pressure will begin to build in over the Spaceport today, causing drier conditions and lighter winds from the north to northeast with upper level winds dropping off as well. A few cumulus clouds could develop over the coast Tuesday morning, which could move over the Spaceport during the launch window. The Cumulus Cloud Rule will be the primary concern for a Tuesday launch attempt. High pressure continues to dominate the area on Wednesday. Winds will continue to be light shifting to the northwest and upper-level winds begin to increase slightly as the jet dips further into the southeastern states. Moisture slightly increases over the Spaceport Wednesday morning increasing the potential for low-topped cumulus clouds to develop. This will cause the primary concern to remain the Cumulus Cloud Rule for a Wednesday launch attempt.
