Ill be curious to see the revised forecast for friday in the morning. Over at TWC, the latest hour by hour forecast has improved since earlier in the day, and shows clearer skies and lighter winds.<br /><br />I've also been looking at TAF's, but they don't cover the launch window yet (they go to Dec 8 0000 UTC, about 2.5hr before thursdays launch).<br /><br />Don't anybody get your hopes up though, Im not a forecaster (but I am a pilot, so I know a bit about interpreting forecasts), so I wouldn't read anything into this until we hear an actual new forecast from NASA. But I'm at least keeping my fingers crossed.<br /><br />Can someone verify this: My understanding from the press conference slides, was that for Shuttle flights the ceiling is interpreted in the same way that traditional flight ceilings are, with the lowest BRK(5/8) or greater deck, and that SKT (4/8) and below are ok below that, as long as clouds are not thicker then 500ft? I read over some of the constraint rules I could find, and that was the gist I came away with. <br /><br />EDIT: To clarify, Im saying that ceiling is traditionally BRK or worse. The 500 ft thing is what I read in the rules I could find. <div class="Discussion_UserSignature"> </div>
