This boundary willbring pre-frontal weather into the Atlantic and nudgethe subtropical ridge axis overthe Spaceport. This will impede the inland progression of the east coast sea breezeand, coupled with the westerlysteering flow, push inland convection towards the Space Coast. The morning sounding shows instability in the moderate range, meaning the convection may hold off until after T-0. The primary concerns are flight through precipitation, as well as the anvil and cumulus cloud rules fromthe convection.On Sunday, the late season frontal boundary will provide some added cloudiness over the Spaceportearly, but will likely push just south of the area by T-0. The primary weather concerns for launch are flight through precipitation, the thick cloud layer rule, and the cumulus cloud rule, associated withthefrontal boundary.Monday and Tuesday will bring a noticeable change to Central Florida, with limited convection and strong onshore winds. The primary concerns for launch are cumulus clouds and flight through precipitation with coastal showers.
