Forecast Discussion

Space Launch Delta 45

The weather outlook for today will play out like yesterday as the front across North Florida this morning continues to sag southward. There will be two main opportunities for storms at the Spaceport today, the first will be with the development of the slow-moving east coast sea breeze early this afternoon. The second, and higher chances, will be as ongoing storms over the eastern Gulf of Mexico and western Florida push east across the peninsula and collide with the east coast sea breeze late afternoon and early evening. While activity is expected to be winding down and moving offshore going into this evening’s launch window, convective debris and anvils from earlier activity will likely linger. The main weather concerns will be the anvil cloud rules and the debris cloud rule with the leftover activity. The front will wash out across the area mid-week, but remaining energy will continue to drive the unsettled pattern. Models are a little more bullish on pushing the front just south of the Spaceport on Wednesday, allowing a northeasterly wind shift, but with the front still close enough to provide additional support for numerous afternoon storms. Showers and storms will likely be on the wane by start of the backup launch window Wednesday evening as they favor areas to the west, but similar to the primary day convective debris and anvils will linger. The main weather concerns for the backup window will remain the anvil cloud rules and the debris cloud rule.
