Forecast Discussion

Space Launch Delta 45

Northwesterly winds behind the cold front centered over the Bahamas has brought dry conditions and much cooler temperatures to the Space Coast. This regime should persist as a sharp upper-level trough lingers in the Atlantic through Thursday morning. Conditions for the primary launch window look very favorable, with low relative humidity values and a weak chance for a Cumulus Cloud Rule violation. The upper levels remain very dry as high pressure settles in today and tomorrow. Any cumulus clouds will be low-topped and only a concern if they linger directly over the pad. For the backup day, similar conditions are expected. Low-level winds will shift more northerly, providing onshore flow and slightly increased moisture near the surface. There remains a small chance for a Cumulus Cloud Rule violation.
