<<...OLE_Obj...>> Eastern Range Operation Forecast Op Number: F2342
Issued: 4 June 0730 AM EDT Valid: 5 June
Vehicle/Payload: STS-111 (Endeavour)/ISS UF-2
Location: Pad 39-A
Launch Weather Officer: Kathy Wintersl
Synoptic Discussion: A significant amount of cloud cover has moved into
Florida from the southwest. The heaviest cloud cover is at approximately
25,000 feet, and the thickness and temperature level of the clouds is a
concern for launch. Additionally, thunderstorms off the southwest coast of
Florida and flow from the west-southwest aloft still raises a concern for
anvils as well. Finally, 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 be strong
enough to cause a concern for crosswinds.
