PEBBLE BEACH, Calif. -- The rain began about 10 p.m. PT on Thursday night and continued intermittently into Friday morning.

A little over three-tenths of an inch of precipitation fell before the clouds parted and abundant sunshine returned around 9:30 a.m. PT as the final groups were teeing off in the second round of the AT&T Pebble Beach National Pro-Am. Some small hail also fell before competition began.

The threat of rain persists until mid-afternoon, though, and -- as if on cue -- clouds are returning to the sky. The temperature will top out around 52 but the winds will be in the 10-20 mph-range.

The weekend will bring more of the same cool conditions but the weather should be dry with more moderate winds. There is a chance of patchy frost on Sunday morning.

PEBBLE BEACH, Calif. -- Scott Langley and his amateur partner, Doug Mackenzie, combined for an 11-under 59 at Monterey Peninsula to lead the pro-am portion after the first round of the AT&T Pebble Beach National Pro-Am.

Mackenzie, who plays to a 3 handicap, is a business executive who sits on the Monterey Peninsula Foundation board of directors.

One shot behind is the team of Brandt Snedeker and amateur Toby Wilt, who plays to a 7 handicap. That duo shot 60, also at Monterey Peninsula.

The Langley and Snedeker teams will each play Spyglass Hill in Friday's second round.

Among the large group tied for third: Jason Day and his partner, San Francisco 49ers coach Jim Harbaugh; Dustin Johnson and his partner, hockey legend Wayne Gretzky; Patrick Cantley and his partner, surfer Kelly Slater; and Jeff Maggert and his partner, country singer Clay Walker.

POST-SUPER BOWL: According to the San Francisco Chronicle, Harbaugh had a relaxing day on the course.

Asked if he was competitive on the course, Harbaugh told the newspaper: "No, I'm not good enough to get upset about it."

CONDOLEEZZA'S ROUND: Former Secretary of State Condoleezza Rice, among the newest members at Augusta National, beaned a spectator on the sixth hole.

Rice started strong but was clearly rattled after she hit a woman in the head on an errant approach shot on the sixth hole. She faded before the turn and combined with pro Jason Bohn for a 2-under 70.

"Somebody asked me, 'How did it compare to diplomacy?'" Rice said while walking off the 18th green. "And I said, 'Well, I know how to do diplomacy, I'm not so sure about the golf course.'"

PEBBLE BEACH, Calif. -- The rain that was in the forecast for the Monterey Peninsula on Thursday never materialized. In fact, Mother Nature opted for ample sunshine for the bulk of the first round of the AT&T Pebble National Pro-Am.

"I think the most interesting thing was we had perfect weather when it was supposed to rain at noon," said Hunter Mahan, who shares the lead at 6 udner with Russell Know. "We were all expecting rain; the bag probably weighs a hundred pounds right now, can't fit anything more in it. The weather was fantastic."

Friday may not bring such spectacular conditions to these scenic courses, though. The forecast calls for another cold front to arrive overnight and bring a 50 percent chance of rain for most of Friday.

In fact, there could be isolated thunderstorms and small hail during the second round. The temperatures will be in the low 50s with winds from the northeast at 10-20 mph making it seem much cooler.

PEBBLE BEACH, Calif. -- Wednesday night at a reception hosted by CBS, Scott Langley showed he had the gift of gab as he sparred with Jim Nantz and Nick Faldo in an informal Q&A session designed to spotlight some of the PGA TOUR's best young players.

And in Thursday's first round of the AT&T Pebble Beach National Pro-Am, Langley put those physical talents on full display as he shot a 65 on the Shore Course at Monterey Peninsula Country Club that left him one stroke off the lead.
 
"Golf is such a funny game," the 23-year-old said. "I didn't have a ton of expectations coming into today. But I just got out there and got off to kind of a slow start to be honest but kind of picked it up really quickly."

Indeed. The PGA TOUR rookie bogeyed the second hole from a "funky stance" beside the fairway bunker but righted the ship and made seven birdies in his next 14 holes to briefly share the lead. He chose the wrong club at the 17th hole, though, opting for a 4-wood instead of the 7-wood or driver he feels most comfortable with there, found the rough and had to punch out on the way to a closing bogey.

"But I had a lot of good and that's what I take from today, seven birdies," Langley said. "I putted very well. I just, you know, besides the two mistakes, hit the ball very well for the most part."

Langley may be a rookie but he is well-acquainted with these scenic courses on the California coast. He's been here so much he even has a favorite restaurant over on the Monterey wharf where the owner, who is an avid golfer, greets him with a bag of red tees.

Langley's love affair with golf on the Monterey Peninsula essentially began when he teamed with Dana Quigley to win the pro-junior division of The First Tee Open in 2006 when he was 17 and Pebble Beach and Del Monte Country Club were in the rotation. He returned to tie for 16th at the 2010 U.S. Open. 

Langley then became the first former participant of The First Tee to earn his TOUR card last year when he tied for 17th at q-school. He played in last year's AT&T Pebble Beach National Pro-Am on a sponsor's exemption and missed the cut -- but Langley appears to be making up for lost time this week.

"I came here when I was young and I was so amazed at how beautiful this place is," Langley said. "You get distracted a little bit by the views. I remember when I was younger, I came here and played and I was so nervous on 7 and 17, these iconic holes of Pebble Beach. 

"And I feel differently now. I feel more comfortable here, more at ease. I've had good results here so maybe that helps my confidence a little bit."

PEBBLE BEACH, Calif. -- Brandt Snedeker couldn't have asked for a better pairing in the first three rounds of the AT&T Pebble Beach National Pro-Am.

The red-hot Snedeker is playing with fellow Vanderbilt alumn, Luke List, who is a PGA TOUR rookie this season. Not to mention, Snedeker's pro-am partner is investor Toby Wilt, who played football at Vandy and makes his home in Nashville, Tenn., as Snedeker does.

And as it that's not enough of a bond both Snedeker and  List, who is partnered with NBA International president Heidi Ueberroth, attended Vanderbilt on the  Toby S. Wilt Athletic Scholarship.

"We are thick as thieves," Snedeker said. "When we get together, we like to have a good time and it's worked out well that we can play together. We had a lot of fun out there today."

Snedeker probably had more fun than anybody after shooting a 66 at Monterey Peninsula's Shore Course that left him two strokes off the lead. Snedeker made three birdies on the front nine to turn in 31, then added another trio on the back but also dropped two strokes to par.

Not that Snedeker's solid play should come as any surprise. He leads the FedExCup after finishing second the last two weeks and opening the year with a solo third on Maui. Snedeker is the eighth player since 1990 to post runner-up finishes in back-to-back weeks.

"I played really, really solid teed to green," said Snedeker, who hit 10 fairways and 14 greens in regulation. "Made a few putts early to get the momentum going but tough to make a lot of putts over here today. Golf course is in great shape. Greens are a little bumpy but rolled really fast and hard to make a lot of putts on.
 
"All in all it's good start to the week. Got two more days, don't know where you stand so tough Saturday afternoon, so good start.'

PEBBLE BEACH, Calif. --  A week ago, Phil Mickelson flirted with a 59 in the first round on the way to a record-setting victory at the Waste Management Phoenix Open.

On Thursday at the AT&T Pebble Beach National Pro-Am, he battled to break 70 but still found himself in red numbers at the end of the first round. Mickelson's round of 69 came on the Shore Course at Monterey Peninsula, which plays to a par of 70.

Tee to green, Mickelson was solid -- hitting 10 of 13 fairways and all but five greens in regulation. The defending champ couldn't get his putter untracked, though, using a total of 30 in shooting 1 under.

"I played comparable to how I played last week but the differences on the greens, it's a lot more challenging to make a lot of putts up here than it is in Phoenix," Mickelson said.

Mickelson actually played his first 10 holes in 3 under, which would have put him three strokes off the overnight lead. But he couldn't coax it home, closing with two bogeys for the 69.

"I played okay today, and I was 3 under for a while, so it's disappointing to give a couple shots back coming down the stretch," Mickelson said. "I'll have to go out tomorrow at Spy and see if I can get a hot hand."
 
Mickelson is looking to execute back-to-back wins for the third time in his PGA TOUR career. He also seeks to join Mark O'Meara as the only five-time winners at Pebble Beach.

An earlier tee time on Friday will be a positive, and you can expect Mickelson to be aggressive on the par 5s.

"One of the things I've learned over the years here is you need to be patient," Mickelson said. "There's plenty of birdie holes throughout the three courses throughout the first three days. Hopefully I'll get a good run tomorrow and try to shoot myself up into contention. ...

"If I play just a good, solid 18 holes, I should be hopefully be able to shoot something in the mid-60s."

Mickelson also confirmed he will not be playing in the World Golf Championships-Accenture Match Play Championship in two weeks. Next week's Northern Trust Open will be Mickelson's fifth straight start, and it happens to coincide with a school holiday for his kids.

"I am by no means making a statement about the tournament," Mickelson said. "I love the tournament. It's one of my favorite of the year. I love being in Tucson. It's where I won my first PGA TOUR event but my kids are out of school that week and we are taking a family trip."

PEBBLE BEACH, Calif. -- It's always difficult to tell who really leads at the AT&T Pebble Beach National Pro-Am. For the first three days you have the field split among three different courses. Monterey Peninsula is considered the most score-able; Spyglass Hill the most difficult; and Pebble Beach the most exposed to the elements.

Is Hunter Mahan's 6 under at Pebble Beach better than Russell Knox's 6 under at Monterey Peninsula? Seung-Yul Noh's 67 at Spyglass Hill might actually be the best round of the day. With bad weather predicted for the second round, we won't know who truly has the lead until Saturday night when the entire field has played all three courses.

Long John: John Daly had a bad day, shooting 5 over. But he did have a very memorable hole. He reached the 582-yard 14^th hole in two shots. Daly's drive on the par 5 traveled 300 yards, followed by a 282-yard 3-wood that held the middle of the green. Players can reach that green in two, but very few ever hold the putting surface. Daly converted a two-putt birdie for a small victory in a day of disappointment.

Eagles: Heath Slocum had a pair of eagles in the opening round and a numerical oddity. He eagled the sixth hole and the 18^th and both times the putts measured 7 feet, 2 inches. Slocum had  just four eagles in all of 2012 and now has two in the opening round, with both coming from the same distance.

Short game: Lee Westwood knows his game and knows what needs to be improved. He ranked 191^st in scrambling last year and 175^th in strokes gained-putting. Westwood is serious enough about improving that he relocated his entire family to Florida, saying the weather and practice facilities will improve his entire game. In his first PGA TOUR round of the season Westwood hit 16 of 18 greens.

Pace of play: The opening round averaged nearly 5 hours, 30 minutes for each foursome. John Maginnes of PGA TOUR Radio had an interesting observation, saying that slow pace of play is one reason why so many veterans play well in this tournament. The inexperienced golfer grows tired and loses concentration when rounds exceed 4 1/2 hours.

Conditions: This tournament is noted for soft fairways and greens, but not this week. The fairways have some speed and it takes a well-struck golf shot to hold the greens. It is a welcome change. In the past, balls hit the green and you could hear a “splat” and frequently drives in the fairways picked up splotches of mud. It would be wonderful if the dry conditions persisted, but rain is in the forecast for Friday.
