Launch Mission Execution Forecast
Vehicle: STS-114 Return To Flight
Issued: 12 July 2005/1100Z (0700 EDT)
Valid: 13 July 2005
Launch Weather Team: (321) 853-8484
Synoptic Discussion: High pressure is building in over the Western
Atlantic. On launch day, the high pressure ridge will remain north
of KSC causing southeasterly flow over the area. Morning coastal
showers are expected, and possibly thunderstorm activity over KSC
as the sea breeze develops during the late morning/early afternoon,
but the sea breeze should migrate inland by launch time. Still,
there is a threat the storms associated with the sea breeze will
be within 20NM of the Shuttle Landing Facility at launch time,
causing a concern for Return to Launch Site (RTLS) weather.
Additionally, upper level winds from the north-northwest have
increased our concern for anvils from thunderstorms migrating into
the area; therefore, the probability of KSC weather prohibiting
launch increased to 40%.
