ARDMORE, Pa. – In a golf season that so far has been dominated by weather, it is little surprise that a few thunderstorms could disrupt the final round of the 113th U.S. Open.
There is a 40 percent chance of scattered showers and thunderstorms at Merion between 8 a.m. and 2 p.m. Sunday, with the likelihood increasing to 60 percent between 2 and 8 p.m.
The high temperature will top out at 85 degrees, and the wind will intensify throughout the day as well, with gusts over 15 mph in the afternoon.
The forecast is problematic, of course, with the final group of Phil Mickelson and Hunter Mahan set to tee off at 3:20 p.m. ET. It is unclear why the USGA opted to send the final groups out so late, given the threat of inclement weather. Sunset is approximately 8:32 p.m.
If final-round action is extended into Monday, players will be greeted by warmer and muggier conditions, with a high temperature of 89 degrees but only a 20 percent chance of precipitation.
