Forecast Discussion

Space Launch Delta 45

The low pressure system that developed off the east coast of Florida yesterday has already moved well up the eastern US coast and pulled a strong cold front through the state this morning. Brisk northwesterly winds will continue, bringing clear, dry, and cold conditions to the Spaceport. The Arctic high in the system’s wake will settle into the Gulf of Mexico by late today, before sliding into the central Gulf on Sunday. Winds will quickly diminish late this evening and into the launch window Sunday afternoon. Only a few low topped cumulus clouds are expected to be present, though these may be cold enough for a Cumulus Cloud threat during the window. Weather continues to be favorable into Monday as the high center slides east across the Florida peninsula. Dry conditions remain into the launch window Monday afternoon, with a few more cumulus clouds as light low level flow turns east off of the Atlantic. There will only be a small concern for Cumulus Clouds during the backup launch window.
