Forecast Discussion

Space Launch Delta 45

Forecast Discussion: A cold front, that is currently bringing severe weather to the Central United States, will move over the Florida Panhandle by Thursday morning. Although any storms associated with that front will be well to the northwest of the Spaceport during the primary window, cirrus clouds from that system will likely be overhead. There is a low chance these cirrus clouds violate the Thick Cloud Layers Rule, but if they do, it may be for an extended period. Additionally, there is a small chance for flight-through Cumulus Cloud Rule violations on the primary day. By Thursday evening, the cold front is expected to bring isolated showers and thunderstorms, some of which may produce strong winds and small hail, to the local area. As the front passes, windspeed will increase, possibly above liftoff constraint, but are expected to start gradually decreasing early Friday morning. Additionally, wind direction will become onshore after frontal passage, bringing a risk of occasional flight-through Cumulus Cloud Rule violations. Notably, the cold front will also bring poor weather to the booster recovery area Thursday night and Friday morning.
