Shuttle launch weather forecast for Wednesday, June 5

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.
