Transporter-2 - L-2 Days

The subtropical ridge axis remains south of Central Florida, creating southwesterly flow hindering the inland progression of the east coast sea breeze each day. This creates higher chances for storms developing near the Spaceport, as well as driving inland storms eastward each afternoon and evening. Elsewhere a boundary in North Florida will gradually erode as the associated low pressure area pulls northward. As this boundary erodes, the subtropical ridge axis will begin to move north of the Space Coast. There is uncertainty on the timing of this transition, but most of the models have it north of the Spaceport on Friday. This will mean less storm coverage as the east coast sea breeze moves rapidly inland and drives any storms westward. The primary launch weather concerns Friday afternoon are the Cumulus Cloud Rule and the Thick Layer Cloud Rule associated with the lingering boundary. On Saturday, models agree the subtropical ridge axis will be well north of the Spaceport and only scant remnants of the lingering boundary will remain. The primary weather concerns for a Saturday afternoon launch attempt are the Cumulus Cloud Rule and the Anvil Cloud Rules from storms developing inland.
