Forecast Discussion

Space Launch Delta 45

Forecast Discussion: The upper-level ridge and surface high which have provided dry conditions and warmer temperatures this week will move offshore this weekend. On Saturday, a low will strengthen over Alabama/Georgia and then push off into the Atlantic by Sunday, dragging a cold front through the Space Coast on Sunday afternoon. For the primary launch window, favorable conditions are expected due to subsidence and dry air aloft from the departing high. Minimal cloud cover and light, southwesterly winds are expected throughout the window. For the backup day, conditions become less favorable as strong northerly winds behind the afternoon frontal passage may violate user wind constraints. Wind speeds will trend upward throughout the backup window, causing increased probability of violation. Frontal showers and thunderstorms will be well off into southern Florida by the launch window, making elevated winds the primary concern.
