Forecast Discussion

Space Launch Delta 45

Pleasant weather will continue across Central Florida as high pressure dominates the region. Warm afternoons with partly cloudy skies and very isolated showers will persist for the next few days. High temperatures will be in the mid to upper 80s along the Space Coast and over 90F inland. A slight chance for showers is also possible over the Spaceport each day, mostly in the mornings as the sea breeze pushes inland. On Wednesday, similar conditions are expected with only a very slight chance of a cumulus cloud moving into the flight path at launch time. On Thursday, the high pressure ridge will begin to weaken, but remain strong enough to suppress convection though the launch window. The primary launch weather concern remains a low chance of a Cumulus Cloud Rule violation.
