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.
