The 125th U.S. Open outside of Pittsburgh at Oakmont Country Club is facing a more unsettled weather pattern this weekend that will bring an increased risk of showers and thunderstorms.

Fast Facts

• Oakmont Country Club is hosting the tournament for a record 10th time this year, with the last one in 2016 when Dustin Johnson won.
• 156 players will take part in the four-day event from Thursday through Sunday, with a cut that reduces the field after Friday.
• The challenging course is known for its iconic "church pews" bunker, as seen in the bottom-middle of the photo above between holes 3 and 4.

Forecast

• Sunday: The final round will have a lingering threat of showers and thunderstorms. A few showers will be possible in the morning before hit-or-miss showers and storms develop once again during the afternoon. Localized heavy rain and lightning are both possibilities, which means there could be interruptions to play. Attendees will want to take a poncho and/or umbrella just in case.
