If you went to bed after Paul McCartney's triumphant Friday night set at the Austin City Limits Music Festival planning to head back to Zilker Park on Saturday, you probably were prepared for rain, as forecasts called for a 70 percent chance of thunderstorms right around the 11 a.m. gate-opening time.

Texas weather changes on a dime, of course. Some precipitation fell earlier in the morning, but by the time the traditional "Star Wars" theme blasted out across the grounds to signal the mad dash of early arrivers, clouds were mostly giving way to sun, and rain chances were down to 15 percent for most of the day.


....aaaand they’re off! Early arrivers at #ACLFest on Saturday sprint for prime spots on the headliner stages. #Metallica and #Justice have the honors tonight. Stay tuned to @austin360 online for news & reviews from the fest throughout the weekend. pic.twitter.com/BEo0OMQpkG

That's good news for fans of both Metallica, Saturday night's headliner, and the Texas Longhorns, who play Baylor at 2:30 p.m. across town Saturday afternoon. Lots of Metallica and UT shirts were spotted among the first wave of festgoers, with Longhorn fans likely planning to watch the game in the ACL Fest beer hall while bands play afternoon sets all around them.

The fortuitous turn in the weather also was good news for bands playing in early slots whose sets might have been canceled had there been a delay. Last weekend, Saturday, gates opened about an hour late, which affected attendance at a few noontime shows but didn't result in any cancellations.
