"I like to play in difficult weather," said Ewart Shadoff.
"Wind or rain is fine – but both can be a bit of a challenge, so I'm glad we had the wind on Friday and the rain on Saturday."
World number four Kang, who won the Women's PGA Championship in 2017, started the second round as an outright leader, but had three consecutive bogeys from the 13th hole.
"It was a very different challenge," said Kang, who scored a 66 in the opening round. "It was a different golf course. Suddenly it is cold, it was raining, everything is wet."
Boutier was one of only nine players to score an underpowered round with her 71 including three birdies.
