Koreasat-6A - L-1 Day

High pressure off the eastern seaboard will bring breezy onshore winds and a slight chance for showers today. By Monday that high will have moved well into the Atlantic Ocean and a trailing ridge axis should be just north of the spaceport. This pattern is expected to open the door for a trough to move out of the tropics and into the local area, bringing a chance for showers and isolated thunderstorms during the primary launch window. By Tuesday, an offshore cold front is expected to pull much of the moisture away from the Cape. For both launch windows, the Cumulus Cloud Rule is the most likely weather constraint concern, with the potential for a violation considerably higher on Monday.
