Inspiration-4 - L-1 Day

Easterly flow along the southern periphery of the Bermuda ridge will keep the Space Coast free of convection by early afternoon. Onshore low-level flow allows the east coast sea breeze to move inland rapidly, keeping most afternoon/evening convection on the western half of the peninsula. On Wednesday, the Spaceport will be sandwiched between two tropical systems with Nicholas over Louisiana and a weak circulation northeast of the Bahamas. This will weaken the low-level flow along the Space Coast, but liftoff weather continues to look favorable. Depending on how far north the Bahama system’s influence extends, the ascent corridor could see elevated winds and precipitation. The primary launch weather concerns are Flight Through Precipitation with coastal showers and the Anvil Cloud Rule associated with inland storms. On Thursday, the Atlantic tropical system will likely move east of South Carolina as the remnants of Nicholas approach the Florida Panhandle. This will change the overall wind pattern across Central Florida, making it southwesterly with convection closer to the east side of the peninsula. The ascent corridor remains a threat for elevated winds and precipitation with the tropical system in the vicinity. The primary weather concerns for a Thursday launch attempt are Flight Through Precipitation and the Debris Cloud Rule from the afternoon’s convection.
