The 125th U.S. Open outside of Pittsburgh at Oakmont Country Club will see a more unsettled weather pattern as we head into the 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

• Friday: The high temperature will be right around average for Pittsburgh this time of year, topping out in the low 80s. We are also watching a cold front coming into Pennsylvania that will eventually stall. This front will increase cloud cover and it could produce hit-or-miss afternoon showers or thunderstorms.
• Saturday: The threat of rain increases as surging moisture out of the west-southwest combines with a front lingering nearby. This could be from a combination of rain showers ongoing in the morning followed by possible scattered thunderstorms in 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.
• Sunday: The final round will have a lingering threat of showers and thunderstorms. The morning is likely to be dry, but the afternoon could have some hit-or-miss scattered showers and storms. You can use this link to see the Oakmont local forecast.
