Forecast Discussion
Space Launch Delta 45
Forecast Discussion: High pressure will linger over the Western Atlantic through the weekend, bringing onshore, easterly flow to Central Florida through the period. Light showers could move over the Spaceport at times this weekend, with the best chance being in the late morning and early afternoon there is a small chance of Cumulus Cloud Rule violations for the primary and back-up launch opportunities.
