Forecast Discussion

Space Launch Delta 45

Forecast Discussion: The subtropical ridge axis will move south of the Spaceport by Friday, leading to an influx of tropical moisture. Westerly-to-southwesterly low-level winds will bring prime conditions for afternoon showers and thunderstorms along the east coast of Florida for several days, some of which could develop in the morning hours. For both the primary and backup launch windows, isolated showers and thunderstorms could develop towards the end of the windows, with possibly lingering anvil clouds towards the beginning of the windows.
