The weather at Southern Hills Country Club has already played its part this week at the PGA Championship, with significant Open-style good/bad sides of the draw.
The early-late starters had it best, after windy conditions on Thursday afternoon and Friday morning for those on the much more difficult late-early side.
So, how is it looking for the weekend?
Temperatures on Saturday and Sunday are set to be around 20F degrees lower than those on Thursday and Friday, and Saturday is looking to be wet and windy.
Saturday
The weekend is set to bring cooler weather, with highs of 21C (70F) on Saturday, a big drop compared to the opening two days. There is a 60% chance of rain with scattered showers predicted, and the thunderstorms will still be about too. The wind switches on the weekend significantly, so the course will be playing completely differently.
Sunday
The final day should be more settled, with just a 12% chance of rain and intervals of cloud and sunshine predicted. Temperatures will be around 68F (20C) and the wind should drop a little too, down to 10 to 15MPH, meaning the weather should have little impact on who goes on to win this year's PGA Championship
