Forecast Discussion

Space Launch Delta 45

Expect continued hot and humid conditions with daily afternoon and evening thunderstorms across Central Florida through Thursday. The thunderstorms will favor the Atlantic side of Florida as the subtropical ridge axis remains south of the Space Coast. Luckily, the launch window extends past the typical life span of the convection, creating good chances weather will clear by the end of the window. The primary launch weather concerns for are the Anvil and Cumulus Cloud Rules associated with the day’s storms, which will diminish through the window. On Friday, the subtropical ridge axis will begin to shift northward, slightly decreasing the storm coverage near the Spaceport. However, the primary launch weather concerns remain the Anvil and Cumulus Cloud Rules.
