Forecast Discussion

Space Launch Delta 45

A weak frontal boundary will move into North Florida later today before stalling out across Central Florida. An area of low pressure will develop along this boundary over the Gulf of Mexico on Thursday, strengthening as it crosses the Florida peninsula Friday and Saturday. Stormy and windy conditions will accompany the low passage across Florida, with the low center expected to be northeast of the Cape by the primary launch window late Saturday night. Scattered showers wrapping around the backside of the low into the Spaceport will be the main concern for this launch window, along with liftoff winds with the rapidly deepening low center nearby. The low will move up the southeastern US coast on Sunday, wrapping dry air into the state and bringing cool and breezy conditions for the backup launch windows. The main concerns for both a Sunday night and Monday night attempt will be a few Cumulus Clouds.
