Forecast Discussion

Space Launch Delta 45

A foggy start along the Space Coast today should give way to partly cloudy skies with afternoon temperatures in the 80s. Elsewhere, a low pressure area will move into the North Atlantic, dragging a front along the Eastern Seaboard and into North Florida. This front will push into the Central Florida on Saturday, bringing clouds and isolated showers to the area as well as cooler air. The front will be south of the Spaceport by Sunday, as high pressure builds back into the region. The primary concerns for a Sunday morning launch are Liftoff Winds and the Cumulus Cloud Rule associated with the onshore flow and isolated coastal showers. On Monday, another low pressure system will develop in the Great Plains region, but high pressure will continue to dominate Central Florida, keeping favorable launch conditions at the Spaceport. The primary weather concern Monday remains the Cumulus Cloud Rule, associated with very isolated showers along the periphery of the high pressure area.
