Forecast Discussion
Space Launch Delta 45
A surface front stalled north of the Spaceport will increase easterly flow today, helping the sea-breeze to develop and move more inland this afternoon. Heavy rainfall is possible in storms through today, then drier air will move across the region mid-week. The front to the north may begin to dissipate Tuesday into Wednesday, however there is the possibility of showers and an isolated thunderstorm near or just off the Spaceport coast in the mornings Tuesday and Wednesday. The Cumulus Cloud Rule and Anvil Cloud Rules are the concerns for the primary launch window and Cumulus Cloud Rule is the concern for the backup launch window.
