Forecast Discussion

Space Launch Delta 45

Remnants of a weak surface boundary will move from the Atlantic coastal waters across the state today with our highest chances of showers and isolated thunderstorms by late-morning through early afternoon. The activity will continue to progress westward with help from the sea breeze allowing for clearing conditions along the coast by the evening hours. Overnight and into tomorrow, high pressure will build in from the north bringing drier conditions across the Space Coast. Onshore flow will persist through the overnight hours with only a slight concern for the Cumulus Cloud Rule during the launch window. For the backup day, moisture begins to return as high pressure moves eastward over the Atlantic, so chances of onshore showers will slowly increase.
