Forecast Discussion

Space Launch Delta 45

High pressure will build at the surface over central Florida through Saturday. This will keep us dry for MLP Roll day today with light winds and near average temperatures. The surface high retreats into the Atlantic Ocean slightly Sunday into Monday, bringing light winds Sunday becoming from the south on Monday, and a slight chance for isolated low topped showers near the coast, especially on Monday. Therefore, the primary concerns for both launch day and backup day are the Cumulus Cloud Rule.
