The tarp was unfurled at 7:25 p.m. ET, jeopardizing the scheduled 7:57 p.m. start time. As of 7 p.m., Weather.com was forecasting a 25 percent chance of showers at 8 p.m., with temperatures around 65 degrees. Though there was a 55 percent chance of precipitation at 9 p.m., the probabilities lowered from then until midnight.
The National Weather Service called for rain on Saturday, mainly before 11 p.m., with a low around 51 degrees and a west wind around 11 mph. The chance of precipitation had dropped to 80 percent, with new rainfall amounts between a quarter of an inch and a half-inch possible.
AccuWeather.com was reporting that there would be a 40 percent probability of precipitation between 7 p.m. and 10 p.m. in Philadelphia, with temperatures around 63 degrees for the scheduled first pitch. Showers could continue off and on trough the middle innings.
"The best chance of heavier rain will not begin until the later innings," wrote Accuweather.com's Eric Reese. "Any extra innings that may need to be played could end up being pretty soggy."
The forecast was to improve for Sunday's scheduled Game 4 -- a matchup of the Yankees' CC Sabathia and the Phillies' Joe Blanton -- with showers from the current system ceasing early in the morning and allowing for partly cloudy skies toward game time, AccuWeather reported.
Of course, the idea of a wet World Series contest should not be foreign to anyone who paid attention to the Phillies' 2008 postseason run.
Game 3 of the 2008 World Series between the Phillies and Rays was delayed for one hour and 31 minutes due to rain. The deciding Game 5 was started on Oct. 27 but suspended in the sixth inning, making it the first game in World Series history not to be played through to completion or declared a tie.
Last year's Game 5 was resumed on Oct. 29, when the Phillies defeated the Rays, 4-3, and celebrated their first championship since the 1980 season.
