Forecast Discussion

Space Launch Delta 45

A developing low pressure system will make its way into the Tennessee Valley today, while high pressure remains in control across Central Florida. By Friday, the low pressure area will move into the North Atlantic, dragging a front along the Eastern Seaboard and into North Florida. The front will push through the Space Coast on Saturday, bringing clouds and isolated showers to the area as well as cooler air. The front should push 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.
