Eastern Range Operation Forecast Op Number:  F2342 Issued:   3 June 2002/0700 EDT Valid:     5 June 2002      	

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

Location: CX 39A

Launch Weather Officer: Kathy Winters

Synoptic Discussion: Weather conditions are improving at KSC. With a high-pressure ridge building into North Florida on Wednesday, winds associated with the pressure gradient will shift to the southeast near the surface and east through the mid-levels. With this type of flow, the sea breeze that begins late in the morning will push well inland. With plenty of moisture still evident in the atmosphere, thunderstorms will again be generated by low-level convergence associated with the sea breeze, but storms will continue to move west, away from KSC, after forming. Still, winds at 35,000 to 45,000 feet will be from the west resulting in a threat from anvil clouds generated by these inland thunderstorms.
