Update: Play is scheduled to resume at 5:35 p.m. ET.
The first round of the 2013 PGA Championship is currently in a weather delay with some inclement weather approaching Oak Hill Country Club.
The horn sounded at 4:25 p.m. ET with roughly half the field still on the course. Some overnight rain hit Wednesday and there have been reports of thunder during the latter part of the first round. Based on the forecast, it appears a significant thunderstorm is on its way.
It doesn't, however, appear the delay will keep players from getting back on the course on Thursday. Kerry Haigh, the PGA's chief championship officer, said it looks like the poor weather will continue until roughly 5:30 p.m. and officials are hopeful play will resume. Haigh said sunset is 8:22 p.m. and they could play until that time after players are given time to warmup.
Significant rain could give the players still playing an advantage as the greens will get even softer and more responsive. Haigh said weather could also be a factor on Friday, but the forecast for the weekend looks promising.
Phil Mickelson, Adam Scott, Justin Rose and Rory McIlroy are among the notable names still on the course. Mickelson, Scott and Rose are on the tee at No. 11 while McIlroy is on No. 12.
