STS-117 Launch Weather Forecast
Vehicle: STS-117, Atlantis
Issued: 6 June 2007/ 1100Z (0700EDT)
Valid: 8 June 2007/ 2332 - 2343Z (1932 - 1943EDT)
Launch Weather Team: 45th Space Wing, Patrick AFB, FL
Synoptic Discussion:
A high pressure ridge over South Florida is migrating north. Due to the
lighter southwest winds over Central Florida, a sea breeze will develop this
afternoon along the coast. Also, moisture is increasing in the atmosphere
over Central Florida; therefore, afternoon thunderstorms, including the
potential for severe weather, are forecast for Kennedy Space Center today.
As the ridge continues to move northward through Friday, Central Florida
will continue to have afternoon thunderstorms each day. By Friday, the high
pressure ridge will be over the Central Florida area, allowing the sea
breeze with associated weather to push inland away from the coast by the
late afternoon and evening. Upper level winds will be from the east Friday,
so anvils from inland thunderstorms should remain inland by launch time.
Our primary concern for launch day is thunderstorms with associated anvils.
