Forecast Discussion

Space Launch Delta 45

A frontal boundary is over Central Florida creating significant cloud cover and isolated rain showers. On Sunday, the front will continue to erode over the Spaceport as high pressure builds in from the north. This will decrease the cloudiness and shower coverage through the day. The primary weather concerns Sunday are Cumulus Cloud Rule and the Thick Cloud Layer Rule associated with the lingering frontal effects. On Monday, the high pressure area will become more of an influence across the Space Coast, further diminishing the strength of the frontal boundary and pushing much of the cloud cover off to the east. The primary weather concern Monday morning is the Cumulus Cloud Rule.
