Hey, don't put the kibosh on the Crazy 8 Ball. Yes, it's the one that has predicted that Tiger will never again win a major with his current swing.
However, as to it's weather predictions, there were hellish downpours at Oakmont in '73, in '83, and in '94. The Crazy 8 Ball, notes a trend here. The 8 Ball also notes a trend of high temps of +90* that accompany the U.S. Open at Oakmont. With those temps, on that plateau, atmospheric stabilization is iffy at best. Those temps and accommpaning window shaking electrical storms are currently here today (Friday,) and will likely be hovering over Oakmont next week at this time.
However, to the delight of golf fans everywhere, the Crazy 8 Ball does see a precip clear weekend with rain most likely in the early rounds. It's best conjuring says Friday and into Saturday morning. So look for the lowest scores of the Open on Saturday, and somewhat drier conditions on Sunday.
The 8 Ball also reminds you to not go looking way over the watermark of "God Almighty Par" for a final score. In fact, if conditions become benign due to moisture, one or two under might be the number.
Remember, you heard it from the Crazy 8 Ball first.
Oh, check out the story on the hotel prices.
