There's a 60 percent chance that weather will be acceptable for launch of Endeavour today or a 40 percent chance conditions will again cause a scrub, according to the briefing given to mission managers this morning.

The forecast for the 6:03 p.m. EDT liftoff time includes showers and thunderstorms inland, a few clouds at 3,000 feet, scattered clouds at 8,000 feet and 25,000 feet, visibility of 7 miles, launch pad winds from the southeast at 8 peaking to 12 knots and a temperature of 83 degrees F.

Liquid hydrogen loading to 100 percent has been completed. The tank will be replenished through the rest of the countdown to replace the supercold propellant that naturally boils away.
