Forecast Discussion

Space Launch Delta 45

Intermittent cloudiness today will give way to mostly cloudy skies with isolated showers on Saturday as the boundary waves back over the Spaceport. The primary launch weather concern for a Saturday evening attempt will be Flight Through Precipitation, the Cumulus Cloud Rule, and the Thick Cloud Layer Rule. During the back-up launch window Sunday evening, most of the shower activity is expected to be displaced across the interior and western portions of the peninsula, but a few showers and mid-level clouds may persist locally. The main concerns for Sunday evening attempt will be Flight Through Precipitation and the Cumulus Cloud Rule. On Monday evening, the stagnant pattern remains, therefore the primary launch weather concerns remain Flight Through Precipitation and the Cumulus Cloud Rule.
