Launch weather forecast
Posted: June 13, 2007

 Forecast for Thursday, June 14

Issued: Wednesday, June 13
Launch Weather Officer: 45th Weather Squadron

Synoptic Discussion: "A surface boundary is over Central Florida with an upper level trough to our West. The boundary is expected to slowly migrate South through the next 24 hours. Expect the seabreeze to develop near the coastline by late morning with showers and thunderstorms developing along the seabreeze boundary. The seabreeze will slowly push inland by early afternoon. The upper level trough and surface boundary coupled with afternoon heating will enhance showers and thunderstorms with the potential for severe thunderstorms. Steering level winds will transport thunderstorms back toward the East coast by mid afternoon.

"On launch day, the boundary is to our south 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, similar conditions persist with a continued drying trend and Easterly surface winds. The primary concern for a 24 hour delay are cumulus clouds, disturbed weather, and isolated thunderstorms."
