While the early groups faced some rain on Thursday morning, most of the field for the 146th Open Championships had conditions not usually associated with the season's third major. Sunny skies paired with low scores and by the end of the day the course that saw Padraig Harrington win at 3-over par in 2008 had 39 under-par scores on the leaderboard with Jordan Spieth, Brooks Koepka and Matt Kuchar at the top after shooting 65. 

"I thought today's round was extremely important, as they all are, but given the forecast coming in, I thought you really needed to be in the red today," Spieth told reporters after the round. "You can certainly make up ground, in a round like tomorrow, and we'll see it happen, but being able to kind of play with shots or play a little more conservative, you make a bogey, because you don't try to do too much on a day like tomorrow, that's nice and very helpful."

That forecast, as Spieth mentioned looks much more similar to what most golf fans think of for The Open. There's a better than 50 percent chance of rain in the forecast for all three remaining rounds with penalizing winds coming Friday.
