Lewis, who attended the University of Arkansas in nearby Fayetteville, collected her 11th career victory and third of the season with a 12-under-par 201 in the 54-hole event.
She also won the North Texas LPGA Shootout and ShopRite LPGA Classic, but she admitted this one was tougher.
"It's so hard to play here," said Lewis, who was the focus of exuberant support from the crowd. "I can tell you I was more nervous today than I was at the US Open last week. That's just how much this place means to me."
New Zealand teenager Lydia Ko also fired a final-round 65 to jump into a share of second place with US veteran Cristie Kerr (67) and American Angela Stanford (67) on 202.
South Korea's Ryu So-Yeon closed with a 69 for 203, one stroke in front of Chella Choi, of South Korea, and Norway's Suzann Pettersen.
American Michelle Wie, who was coming off her first major title at the US Women's Open at Pinehurst, held a two-stroke lead going into the final round but tripped to a two-over 73 to fall into a share of eighth place on eight-under 205.
Seventy-two players had to complete the second round on Sunday morning after storms halted play on Saturday, although Wie was already in the clubhouse with the lead on Saturday night.
