Forecast Discussion

Space Launch Delta 45

Forecast Discussion: The subtropical ridge axis will be south of the Spaceport by Friday. For the next several days, an influx of moisture and westerly-to-southwesterly low-level winds will bring prime conditions for afternoon showers and thunderstorms along the east coast of Florida. For both the primary and backup launch days, there is high likelihood of weather violations. Almost every rule will have a chance to violate but the Cumulus Cloud Rule, Anvil Cloud Rules, and Surface Electric Fields Rule are the most likely.
