Forecast Discussion
Space Launch Delta 45
A rather benign weather regime will remain in place across the Space Coast through the remainder of the weekend into the middle of next week. Surface high pressure is expected to develop over the western Gulf of Mexico and will extend into the southeastern U.S. As a result, there will be light winds during the launch window and limited low-level moisture. The primary concern for a Wednesday evening launch is a few Cumulus Clouds with the onshore flow. In the event of a 24-hour delay, identical weather conditions are expected and the primary launch weather concern remains Cumulus Clouds.
