Forecast Discussion

Space Launch Delta 45

With the high pressure ridge anchored across the Florida Straits, a frontal system draped across North Florida has slowed. This boundary will bring some added mid and upper-level clouds across Central Florida today, but begin to erode as it tries to push south into the strong ridge. On Saturday, the frontal system will likely be over the Space Coast, bringing isolated showers to the Spaceport while further enhancing the mid-level cloudiness. The primary launch weather concerns Saturday morning are the Thick Cloud Layer Rule associated with the frontal cloudiness and the Cumulus Cloud Rule associated with the showers. On Sunday, the boundary will continue to erode overhead as high pressure builds in from the north. This will begin to decrease the cloudiness and shower coverage through the day. The primary weather concerns Sunday remain the Cumulus Cloud Rule and the Thick Cloud Layer Rule associated with the lingering frontal effects.
