Still, the biggest impression left on Federer — who won the Australian Open last month in 40 C (104 F) summer temperatures — might have been the below-freezing temperatures.
"I'm finding it cold," Federer quipped in an interview with the French-language Swiss state broadcaster. "It's not usual for me, especially sitting here in the cold."
Federer, who has a mountain home close to nearby Lenzerheide, said he felt lucky seeing both downhills — the first time in 10 years the prestigious races ran back-to-back at worlds. Fog on Saturday had forced the scheduled men's start to be postponed.
At 32, Vonn set a world championships record as the oldest ever women's medalist.
"I'm old and I'm proud!" joked Vonn, who has four career medals in worlds downhills, though only one gold to add to her 2010 Olympic title.
It is now eight years and four races since Vonn was world champion in her specialist event, yet a medal here had often seemed unlikely.
She suffered yet another season-ending knee injury last February, and broke her right upper arm in November. That sidelined her until mid-January and left lingering problems with her right hand.
"The bronze feels to me like gold. I felt unprepared coming in but I did the best I could," said Vonn, who ceded status as pre-race favorite to Stuhec. "I was not as confident as her and she outperformed me. She definitely deserved the gold medal."
Stuhec was 0.40 seconds ahead of surprise runner-up Stephanie Venier of Austria, whose previous career-best downhill result was seventh.
Vonn was 0.45 behind Stuhec, who led at all but one time check and clocked the fastest speed of 125.6 kph (78 mph).
The 26-year-old Stuhec had no career top-3 finishes entering the World Cup season, yet took advantage of Vonn's absence to win the first three downhills.
Victory was a shared triumph for the Stuhec family. Her mother, Darja, is the technician preparing her skis.
"I can't describe it," said Stuhec, whose mother joined her after several knee injuries cost her funding from Slovenia's ski federation. "It's amazing where we have come since then."
Stuhec kept the world title in Slovenia as she succeeded the 2015 downhill gold medalist, Tina Maze, now retired though working course-side Sunday.
