Issued: Monday, June 11
Launch Weather Officer: 45th Weather Squadron
Synoptic Discussion: "A weak cold front/boundary is in North Florida and will gradually migrate South and off into the Atlantic over the next 36 hours. The seabreeze will develop by late morning with isolated showers and thunderstorms forming along the seabreeze. High pressure remains suppressed to the South through the week with Southerly to Southwesterly surface winds in the morning becoming Southeasterly by late morning with the development of the seabreeze. Steering level winds transition on Monday and become Westerly with afternoon and evening thunderstorms favoring the East coast.
"For (mobile launch platform) roll, an upper level disturbance is expected over the peninsula enhancing the likelihood of late morning thunderstorms coupled with the seabreeze development. Showers and thunderstorms developing along the sea breeze will favor the East coast during the afternoon and evening.
"On launch day, high pressure remains suppressed to the South with Southwesterly surface winds. Expect winds gusting to 20 knots (230 feet). Steering winds and anvil level winds remain form the West acting to transport showers and thunderstorm toward the East coast. Expect showers and thunderstorms to develop by late morning along the seabreeze.
"The primary concerns for launch day are cumulus clouds, disturbed weather, and isolated thunderstorms.
"In the event of a 24 hour delay, similar conditions prevail with Southwesterly surface, steering level, and anvil level winds."
