Starlink 6-3 - L-1 Day

A late-season boundary is approaching northern Florida today, increasing the moisture and instability over the peninsula. This will create increased shower and thunderstorm chances along the Space Coast during the afternoon and evening. A similar set up is expected tomorrow with the addition of a weak circulation center forming along the boundary stalled across Central Florida. This will cause the convection to linger into the overnight hours Thursday into Friday, producing possible Anvil, Debris and Cumulus Cloud Rule violations at the Spaceport. Most guidance indicates the circulation center will move north through the day Friday, allowing any afternoon convection to dissipate by the back-up opportunity’s launch window overnight Friday into Saturday. The primary launch weather concerns are the Anvil and Cumulus Cloud Rules that may be slow to dissipate overnight.
