Forecast for Thursday, June 14

Issued: Tuesday, June 12 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." Clouds: Cumulus scattered at 2,500 feet with tops at 15,000 feet; and Cirrus broken at 24,000 feet with tops at 30,000 feet Visibility: 7 miles Launch Pad Winds: Northeasterly from 030 degrees at 14 to 20 knots Temperature: 78-80 degrees F Relative Humidity: 70 percent Weather: Isolated showers and thunderstorms Solar Activity: Low Probability of Violating Weather Constraints: 30 percent Concerns: Thick clouds, disturbed weather and isolated thunderstorms
