Forecast Discussion

Space Launch Delta 45

Forecast Discussion: Another stormy afternoon is likely across the Spaceport with isolated severe weather possible as westerly flow aloft remains in place. Late tonight into Wednesday morning, a late season ‘cool’ front will move southward across the Florida peninsula, unfortunately making weather conditions tricky for launch. Scattered marine showers will likely scrape the East-Central Florida coastline during the launch window, and plentiful mid-level cloud decks will create concerns for both the Cumulus Cloud and Thick Cloud Layers Rules, with Surface Electric Fields Rule being a distant third should any of the showers move ashore. Latest hi-resolution guidance has provided a more pessimistic view of the shower and mid-level cloud coverage during the launch window; thus we have increased POV. Recovery weather will also be a watch item with elevated wave heights and fresh breezes along the eastern Atlantic. For the backup launch window Thursday morning, weather conditions improve with dry air filtering into the Spaceport behind the front. Marine showers may still exist but will be few and far between with fresh winds out of the east-northeast. Mid to upper-level clouds will persist but will most likely be too high to pose an LLCC concern.
