Forecast Discussion
Space Launch Delta 45
A pattern shift will take place tomorrow across Central Florida as a weak surface boundary is expected to arrive, bringing clouds, isolated rain showers, and gusty winds. This pattern will remain in place over the Space Coast for several days. The primary launch weather concern for the initial launch attempt will be isolated showers and gusty winds associated with the stalled boundary. On both back up days, the base of the upper-level clouds will lower beneath the -20°C level, adding a thick cloud concern to the isolated showers. The ascent corridor weather will also deteriorate over the weekend, with precipitation and unfavorable winds continuing for several days.
