CRS-27 - L-1 Day

A strong cold front is moving into North Florida this morning accompanied by showers and storms. This activity will continue to move into the Spaceport through the afternoon, with a chance for a few stronger storms into the late afternoon. Behind the front, high pressure spilling out of the Midwest will be the dominant surface feature, but an upper- level disturbance moving across the Gulf of Mexico will bring enhanced mid and upper-level cloud cover Tuesday afternoon and evening. This will pose a Thick Cloud Layer Rule concern for the primary launch window Tuesday evening. The upper-level feature will move east of the area on Wednesday, clearing skies as the surface high center moves into the eastern US. No significant weather is expected, with favorable weather for the backup window Wednesday evening. The Spaceport will be on the western end of high pressure by Friday evening, with the next front still well to the west. The increasing pressure gradient ahead of this system however will bring gusty southeasterly winds that will pose a Liftoff Wind concern for a 72-hour delay.
