Launch weather forecast
Posted: July 30, 2004

 Forecast for Monday, August 2

Issued: Friday, July 30
Launch Weather Officer: Joel Tumbiolo, 45th Weather Squadron

Synoptic Discussion: "Drier and breezy southeast flow today will lead to early sea breeze development and quick inland penetration. Hence thunderstorm activity Fri-Sat will be widely scattered, and mainly over inland and western Florida. The overall drier conditions will be temporary, as moisture levels are expected to again increase by Sunday. Surface winds will turn more south-southwest on Sunday which will result in a later, slower moving sea breeze. This also favors thunderstorm activity on the eastern side of Florida.

"On launch day, the main concern will be the conditions at the time of MST Rollback. During the launch window, any activity should be over the Gulf Stream, will a chance of a shower or thunderstorm approaching from the south-southwest."
