Forecast Discussion

Space Launch Delta 45

A brisk day along the Space Coast will transition to a clear evening with winds slowly diminishing after sunset. On Tuesday, high pressure will settle overhead, making for another chilly morning with low temperatures near 45°F at the Spaceport. Skies will continue to be mostly cloud-free and with winds becoming light and variable, making excellent weather conditions for a Tuesday evening launch attempt. On Wednesday, the high pressure area will slide east over the western Atlantic, shifting winds along the Space Coast southeasterly. This wind flow can bring low-topped, brief showers over the Spaceport. The primary weather concern for a Wednesday evening launch attempt is cumulus clouds associated with these showers.
