Forecast Discussion

Space Launch Delta 45

The remnant low pressure across Florida responsible for recent showery weather will subside late today into tomorrow leading to improving weather conditions Thursday into Friday. High pressure across the central Atlantic will maintain an onshore component to the wind, becoming increasingly moist yet again over the weekend as a frontal boundary approaches from the northwest. Thus the primary weather concern for launch day is cumulus clouds potentially associated with showers. For the delay day, the front is expected to settle nearby, allowing additional moisture convergence and a greater potential for showers and layered thick clouds.
