Forecast Discussion
Space Launch Delta 45
Surface high pressure situated across the central Atlantic will provide dry weather today into tonight. A frontal boundary is forecast to approach from the northwest Saturday, with the onshore component to the wind becoming increasingly moist and unstable over the weekend. Therefore the primary weather concern for launch day is cumulus clouds potentially associated with showers in advance of this front. For the delay day, the front is expected to stall nearby, allowing additional moisture convergence and a greater potential for showers and layered thick clouds.
