Forecast Discussion

Space Launch Delta 45

Forecast Discussion: A surface ridge axis just south of the Spaceport will remain nearly stationary today into tomorrow before getting shunted farther south early next week in response to developing low pressure off the Carolina coast. Flow aloft will be weak and variable, supporting daily storm motions that will be seabreeze and outflow dependent. This erratic nature of storm motion is more evident in today’s model runs, suggesting a higher risk of storms lingering closer to the coast later into the night. However, remnant storms and clouds should slowly diminish as the night wears on during both the primary and backup launch opportunities.
