Forecast Discussion

Space Launch Delta 45

A wave will push north over the Space Coast today, increasing cloud coverage and rain chances. The unsettled weather is pulled away early Thursday as the low pressure system moves north along the Atlantic Coast. The primary weather concern for a Thursday launch attempt is the Cumulus Cloud Rule. On Friday, high pressure will build into the area behind the front, creating gusty northerly winds at the Spaceport. The primary weather concerns for a Friday attempt remain the Cumulus Cloud Rule with the addition of Liftoff Winds.
