StarlinkV1.0-L17 - L-1 Day

High pressure stretching across the western Atlantic into Florida peninsula will bring another warm and dry day to the Spaceport. Expect a steady increase in prevailing southeasterly flow, especially with a diffuse sea breeze passage in the afternoon. Not too much change in the pattern as Sunday arrives, with just enough moisture for an increase in afternoon cumulus clouds enhanced by the sea breeze. The primary weather concerns for the Sunday evening launch attempt will be these cumulus clouds along with liftoff winds in the increased southeasterly flow. Uncertainty lingers for a Monday evening launch attempt as some differences remain regarding the speed of the next frontal boundary. While there is agreement that the weakening boundary will be moving through Central Florida Monday evening, there is still disagreement on how quickly. A conservative approach has the boundary on the doorstep of the Cape not too long after the launch window, so still expecting a small threat for showers along with increasing cloud cover. The primary weather concerns for a backup launch attempt Monday evening will be thick clouds and cumulus clouds associated with the boundary.
