Launch Weather Officer: 45th Weather Squadron
Synoptic Discussion: "High pressure is suppressed to the South with low pressure to the North resulting in continued Southwesterly surface winds. The seabreeze will develop by late morning with showers and thunderstorms focused along the seabreeze. Upper level Westerly steering winds will bring thunderstorms over the peninsula back to the East coast by mid afternoon. This pattern persists through the week favoring the East coast of Florida for afternoon and evening thunderstorms.
"For MLP roll, an upper level trough and surface low pressure are over the peninsula that will enhance morning showers and thunderstorms. Thunderstorms are also expected along the seabreeze by late morning. The trough coupled with afternoon heating is expected to produce strong and potentially severe thunderstorms that will track toward the East coast by mid afternoon.
"On launch day, low pressure is off shore with a drying trend and Northeasterly winds. Steering winds and anvil level winds remain from the West acting to transport afternoon showers and thunderstorms toward the East coast.
"The primary concerns for launch day are cumulus clouds, disturbed weather, and isolated thunderstorms.
"In the event of a 24 hour delay, high pressure moves in with a continued drying trend and Northeasterly surface winds. The primary concern for a 24 hour delay are cumulus clouds."
