Forecast Discussion

Space Launch Delta 45

A ridge is expected to settle in over North Central Florida by Monday and remain in place for several days. This ridge should bring southeasterly winds and cause any precipitation and thunderstorm development from the afternoon sea breeze to form well inland of the Spaceport. Any convection that does develop should remain west of Interstate 95 and have decayed away by the launch window. Although unlikely, there is a slight chance of a stray cumulus cloud posing a flight through concern, but the risk appears to be quite low. By the backup day, the setup should be a bit drier but similar otherwise. Currently, there are no specific weather constraint concerns for the backup day. For the second backup day, a detailed forecast is not included below but guidance suggests the potential for a bit more unsettled weather as the ridge axis slips further south and the tail end of a frontal boundary is likely to be working its way into north Florida around that time. Between the location of the front and the southwesterly low-level winds, there would likely be a higher chance for a weather constraint violation if the second backup day were necessary.
