Update x2 (4:54 p.m. ET) -- The rain continues in New York. The USTA had hoped to start at 1:30 and then 2:30 and then 3:30 and then 4:30. Officials continue to insist that there will be a window in which to play tonight, but the forecast suggests otherwise. If play does resume today, all three matches will be played at the same time on Ashe, Armstrong and Grandstand courts.
Update (1:28 p.m. ET) -- A steady rain has delayed the start of the Serena Williams-Kim Clijsters match.
It was going to be like Super Saturday, in reverse. Two great women's matches and a men's match were on the U.S. Open schedule today after rain forced the postponement of last night's quarterfinal between Rafael Nadal and Fernando Gonzalez to this afternoon. But don't expect to see much, if any, tennis today.
The weather report for New York is good only for poncho salesman. Rain features heavily in the forecast through the afternoon, which has caused the USTA to already make contigency plans should no tennis get played.
exercises in guessing obviously tough to predict, so there's still a chance that we may see Serena and Rafa and Kim today. Don't count on it, though.
