Forecast Discussion

Space Launch Delta 45

Southerly winds will keep temperatures elevated in Central Florida and allow daily sea breeze interactions to produce isolated showers and thunderstorms. The tail end of a weakening frontal boundary has stalled northeast of the Space Coast so should have little impact on Spaceport weather. The primary launch weather concerns for a Wednesday morning attempt are the Cumulus and Anvil Cloud Rules associated with any lingering convection. High pressure will begin to build back into Central Florida on Thursday, continuing to the daily cycle of sea breeze interactions. The primary weather concern for Thursday morning is the Cumulus Cloud Rule.
