Launch weather forecast
Posted: July 28, 2004

 Forecast for Monday, August 2

Issued: Wednesday, July 28
Launch Weather Officer: Joel Tumbiolo, 45th Weather Squadron

Synoptic Discussion: "Deep tropical moisture which is fully entrenched over Florida will lead to widespread showers and thunderstorms over the next few days. Southeast flow will lead to early sea breeze development. Expect late morning/early afternoon activity over the coast, with slow migration inland during the afternoon/evening hours.

"Over the weekend expect the same general pattern, although slightly drier conditions may warrant an overall decrease in area coverage.

"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-Southeast."
