Eastern Range Operation Forecast Op Number: F2342 Issued: 30 May
2002/2100 EDT Valid: 31 May 2002 45 Weather Squadron web site:

Vehicle/Payload: STS-111 (Endeavour)/ISS UF-2

Location: CX 39A

Launch Weather Officer: Kathy Winters

Synoptic Discussion: KSC will again have a sea breeze by late morning
generating an easterly flow. With plenty of moisture available in the
atmosphere, the low-level convergence caused by the interaction of the
Florida sea breezes will generate thunderstorms in the center portion of the
state. These storms will move towards the east after development causing
concerns for launch. Additionally, upper level wind flow will be stronger
tomorrow increasing the threat from anvil clouds from the thunderstorms that
form inland.
